THE PEOPLE, Plaintiff and Appellant, v. RAYMOND LAWRENCE FRAZER, Defendant and Respondent, 21 Cal. 4th 737

Opinion BAXTER, J. For many years, the Penal Code has contained statutes of limitation allowing prosecution of alleged child molesters within a fixed number of years after the crime was committed. (See, e.g., § 800.) Recently, the Legislature added

section 803, subdivision (g) (section 803(g)), to the statutory scheme to permit prosecution of such crimes for an additional period—within one year of the time the victim reports an independently corroborated crime to law enforcement officials. By its own terms, the new one-year limitations period applies whether the crime occurred before or after

section 803(

g) became effective. The new law also applies without regard to whether the fixed statute of limitations for the crime has already expired, and had already expired, when

section 803(

g) took effect. Pursuant to

section 803(g), defendant was charged with violating

section 288, prohibiting lewd conduct against children, within one year after the victim reported the crime to the police. The fixed limitations period in existence when the crime occurred had run before the complaint was filed, and before

section 803(

g) became effective. Defendant demurred on grounds

section 803(

g) constituted an impermissible ex post facto law under the United States and California Constitutions, and unfairly deprived him of a statute of limitations defense under the due process clauses of the United States Constitution. No argument was made that a law increasing the time for filing charges can never target defendants who committed their crimes before the new longer statute of limitations was enacted. Rather, defendant challenged the postcrime statutory change only insofar as it affected individuals who, like him, were accused of crimes already time-barred under prior law.

The trial court sustained the demurrer and dismissed the case. The Court of Appeal affirmed. The People sought review of the judgment in this court. For reasons we explain, defendant’s challenge to

section 803(

g) cannot prevail under the formula prescribed in Collins v. Youngblood (1990) 497 U.S. 37 [110 S.Ct. 2715, 111 L.Ed.2d 30] (Collins) for determining when penal legislation triggers ex post facto protection. With respect to defendant’s due process claim, there is no authority specifically authorizing statutes like

section 803(

g) in criminal cases. However, the United States Supreme Court has rejected analogous attempts to retain the benefit of an expired statute of limitations as a matter of substantive due process. The high court has also indicated that any procedural due process inquiries concerning the timing of a criminal indictment are inherently factual in nature. Based on these principles,

section 803(

g) is not unconstitutional per se. We will therefore reverse the judgment. I. Statutory Background California’s criminal statutes of limitation were first enacted in 1851 and codified in 1872. The entire scheme, which currently appears in sections 799 through 805.5, was overhauled in 1984. (Stats. 1984, ch. 1270, §§ 1, 2, pp. 4335-4337.) At that time, the Legislature determined that piecemeal amendment over the years had produced a scheme that was confusing, inconsistent, and lacking in cohesive rationale.

The 1984 revisions sought to balance the state’s interest in barring stale claims against the need to pursue and punish criminal offenders, particularly in serious cases. (Recommendation Relating to Statutes of Limitation for Felonies (Jan. 1984) 17 Cal. Law Revision Com.

Rep. (1984) pp. 307-313 (Statutes of Limitation); see generally, Uelmen, Making Sense out of the California Criminal Statute of Limitations (1983) 15 Pacific L.J. 35.) There is no statute of limitations for murder, embezzlement of public funds, and certain other offenses punishable by life imprisonment. (§ 799.) Otherwise, felony cases, including those involving sex crimes against children, are generally governed by the limitation periods set forth in sections 800 and 801.

Basically, a felony prosecution must be “commenced” either three years (§ 801) or six years (§ 800) “after commission of the offense,” depending upon the term of imprisonment statutorily available as punishment for the crime.

Section 804 describes the circumstances under which prosecution is “commenced” to include the time at which a criminal complaint, indictment, or information “is filed.” (Id., subds. (a) & (b).)

Section 805 makes clear that the “maximum punishment prescribed by statute” determines the applicable limitations period, and also defines the quoted phrase. (Id., subd. (a).) Exceptions to sections 800 and 801 are contained in

section 803. According to subdivision (a),

section 803 sets forth the exclusive circumstances under which such statutory periods may be “extended” or “tolled.” As enacted in 1984, and continuing through the present time,

section 803 suspends the running of the statutory period while another prosecution based on the same conduct is pending against the defendant in state court (id., subd. (b)), delays commencement of the statutory period for certain offenses involving fraud, theft, and breach of fiduciary duty until the crime is discovered (id., subd. (c)), and suspends, within certain limits, the running of the statutory period while defendant is absent from the state (id., subd. (d)). (See also id., subd. (e), added by Stats. 1985, ch. 357, § 1, p. 1509 [delaying start of statutory period until certain Water Code and Health and Safety Code violations are discovered].) Beginning in the late 1980’s, lawmakers across the country became increasingly aware that young victims often delay reporting sexual abuse because they are easily manipulated by offenders in positions of authority and trust, and because children have difficulty remembering the crime or facing the trauma it can cause.

Hence, states which traditionally limited the time for prosecuting child molestation in a manner similar to sections 800 and 801 have started to substantially increase the time in which criminal charges can be filed after the assault occurred. Although they operate in a variety of ways, these new statutes generally apply to crimes committed both before and after their enactment. The new longer statutes of limitation are based on the apparent premise that both past and future sex crimes against children would otherwise go largely unpunished. The California Legislature took similar steps when it added subdivision (

g) to

section 803, effective January 1, 1994. (Stats. 1993, ch. 390, § 1 (the 1994 law).) As originally enacted,

section 803(

g) stated that where certain serious sex offenses were allegedly committed against a victim who was under age 18 at the time, and where the “limitation period specified in

Section 800 or 801 has expired,” a criminal complaint is nonetheless timely if it is filed “within one year of the date of a report to a law enforcement agency” by the victim about the crime. Under the literal terms of the 1994 law, the victim could be “any age” at the time the report was made and the extended period in

section 803(

g) began to run. However, the 1994 statute required “independent evidence that clearly and convincingly corroborates the victim’s allegation,” and circumscribed the manner in which this standard could be met. (Former § 803(g)(2).) Prosecutors promptly invoked the foregoing provisions to file child molestation charges based on the time at which the victim reported the crime, regardless of when the crime occurred or when the statute of limitations otherwise expired. Some lower courts found no statutory or constitutional bar to applying

section 803(

g) even where the limitations period set forth in

section 800 or 801 had expired before January 1, 1994. However, in opinions that were originally published in 1995 and 1996, several Courts of Appeal held that

section 803(g), as first enacted, did not apply where prosecution of the crime was otherwise time-barred as of the statute’s effective date. This line of cases invoked the general rule disfavoring “retroactive” application of statutes in the absence of a clear contrary intent. These decisions relied primarily on the absence of explicit language in the 1994 law stating that it “revived” the state’s ability to prosecute defendants against whom the fixed statute of limitations had run before 1994. Some of these Court of Appeal decisions assumed a contrary

interpretation would violate ex post facto principles. Judicial reluctance to apply

section 803(

g) in older child molestation cases did not go unnoticed by the Legislature. Through an amendment that became operative January 1, 1997, the statute identified in greater detail the cases that could be prosecuted despite delayed reporting of the crime. (Stats. 1996, ch. 130, § 1 (the 1996 amendment or version).) First, the 1996 version retained, without substantive change, all language that had been part of the 1994 law. Thus, according to

section 803(g)(1), as amended in 1996, a criminal complaint is timely if it is filed no more than “one year” after a victim of “any age” reports to a law enforcement agency that he or she, “while under the age of 18 years,” was sexually abused by the defendant. Like its predecessor, the 1996 version applied where the “limitation period specified in

Section 800 or 801 has expired.” (Former § 803(g)(2)(A).) “independent evidence” substantiating the victim’ sallegation was also still required, and was defined no differently than before. (Former § 803(g)(2)(B).) Second, the 1996 amendment added provisions that had not previously appeared in the statute. Critical here is new language which, as explained later in the opinion, targeted the line of Court of Appeal cases declining to apply

section 803(

g) in molestation cases that were time-barred before the law came into existence. Specifically, the 1996 version made clear that the one-year limitations period set forth in

section 803(g) “applies to a cause of action arising before, on, or after January 1, 1994, the effective date of this subdivision.” (Former § 803(g)(3)(A) & (3)(B).) The 1996 amendment also made explicit the Legislature’s intent to “revive any cause of action barred by

Section 800 or 801” where the complaint is filed within one year of the time the victim reported the crime to law enforcement officials, as otherwise required by the statute. (Former § 803(g)(3)(A) & (3)(B)(i).) An overview of

section 803(

g) would not be complete without mentioning that the statute was amended a second time, effective June 30, 1997. (Stats. 1997, ch. 29, § 1 (the 1997 amendment).) The 1997 amendment gave rise to the version of

section 803(

g) which exists at the present time, and which will be cited throughout the opinion. In brief, the 1997 amendment did not disturb core provisions authorizing commencement of a prosecution within “one year” of the date of a report to a law enforcement agency by a person of “any age” claiming that he or she was the victim of an enumerated sex crime “while under the age of 18 years.” (§ 803(g)(1).) The one-year period continues to apply where the “limitation period specified in

Section 800 or 801 has expired,” and where “independent evidence” of a clear, convincing, and specified nature supports the victim’s claim. (§ 803(g)(2)(A) & (2)(B).) However, the 1997 amendment used a new word—“California”—to describe the “law enforcement agency” to which the requisite report must be made. (§ 803(g)(1).) The 1997 amendment also left unchanged language that first appeared in the 1996 version of the statute concerning the state’s ability to file criminal charges in cases that were time-barred before 1994.

Hence, with respect to any complaint or indictment filed within the one-year period provided therein, the statute “applies to a cause of action arising before, on, or after January 1, 1994, the effective date of this subdivision, and it shall revive any cause of action barred by

Section 800 or 801.” (§ 803(g)(3)(A).) In all other respects, the 1997 amendment made changes not directly applicable here concerning cases in which the victim reported the crime after January 1, 1994, and in which a complaint or indictment is filed only after the one-year period in

section 803(

g) has expired, or in which a complaint or indictment filed within one year of the report is dismissed and later refiled. (§ 803(g)(3)(A)(iii) & (iv), (3)(B)(i)-(iii).) Of particular interest in these provisions, however, is language concerning the timeliness of prosecutions instituted, or reinstituted, within a certain time after an opinion of this court, or the United States Supreme Court, finally decides whether “retroactive application” of the statute “is constitutional.” (§ 803(g)(3)(A)(iii) & (iv), (3)(B)(ii), italics added.) II.

Procedural History On October 21, 1996, the district attorney filed a complaint in Mendocino County Municipal Court charging defendant with one count of lewd conduct upon a child under age fourteen in violation of

section 288, subdivision (a) (section 288(a)), a felony. The crime allegedly occurred 12 years earlier, between October 1, 1984, and December 31, 1984. The underage victim was identified as Jessica F. In addition, the complaint alleged that prosecution of the crime was authorized under

section 803(g), which was described as an “exception” to the six-year statute of limitations in

section 800. Defendant demurred on the ground the action was time-barred under

section 800, which “expired as to this charge no later than December 31, 1990.” According to defendant, the complaint could not be considered timely under

section 803(

g) even assuming law enforcement officials received the victim’s report no more than one year earlier. First, defendant asserted, as a matter of statutory

interpretation, that the additional one-year limitations period in

section 803(

g) does not apply where, as here, the six-year period in

section 800 had expired before

section 803(

g) became effective on January 1, 1994. In the alternative, defendant urged that a contrary construction of

section 803(

g) would violate the ex post facto clauses of the United States and California Constitutions, and the due process clauses of the United States Constitution. On February 10, 1997, the municipal court sustained the demurrer and ordered the case dismissed. In a written statement of decision, the court reasoned that

section 803(

g) should be construed in defendant’s favor because, as first enacted in 1994, it did not clearly govern actions that were time-barred before its effective date. However, the court apparently did not consider the 1996 amendment to

section 803(g), which became effective 40 days before the ruling on the demurrer, and which added language bearing on the applicability of the statute in cases such as defendant’s. Having resolved the matter in favor of defendant on statutory grounds, the municipal court did not reach the constitutional questions he had raised. The People promptly moved in superior court to reinstate the complaint.

They argued that the 1996 amendment eliminated any ambiguity in the statutory language, and authorized the filing of molestation charges where the statute of limitations had otherwise expired before 1994, and where the victim reported the crime under the requisite circumstances. The People also urged the court to find no constitutional bar to use of

section 803(

g) in the present case. In opposing the motion, defendant simply renewed all statutory and constitutional arguments previously set forth in the demurrer. The superior court issued a written ruling adopting the People’s construction of the statute. However, the court found that “the clear legislative intent to revive causes of action already barred by statutes of limitation violates the ex post facto clauses of the United States and/or California Constitutions by changing the legal consequences of a defendant’s past conduct.” The motion to reinstate the complaint was denied. The People appealed.

The Court of Appeal affirmed the judgment in a brief opinion that accepted the reasoning used by the superior court in denying reinstatement of the complaint. The Court of Appeal observed that two other appellate courts had invalidated

section 803(

g) on ex post facto grounds insofar as it applied, on its face, to cases that were time-barred before the law was passed. (People v. Bunn (1997) 53 Cal.App.4th 227, 232-239 [61 Cal.Rptr.2d 734] (Bunn); Lynch, supra, 33 Cal.App.4th 1223, 1226-1228.) Like Bunn and Lynch, the court in this case also relied on language in Falter v. United States (2d Cir. 1928) 23 F.2d 420, 425-426 (Falter), which is discussed later in the opinion. We granted the People’s petition for review to address the constitutionality of the statute. III. Application of Statute As a threshold matter, the parties assume here, as on appeal, that

section 803(

g) applies in the present case as a matter of statutory construction. Under this reading of the statute, a felony prosecution which otherwise complies with the requirements of

section 803(

g) is timely whether or not the crime occurred before January 1, 1994, and whether or not the statutory period otherwise applicable under

section 800 or 801 expired before January 1, 1994. Based on the “express language” of the statute, and “extrinsic” evidence in the legislative record, we have no doubt the statute operates in this manner. (Evangelatos v. Superior Court, supra, 44 Cal.3d 1188, 1209.) At no point has

section 803(

g) restricted the amount of time that may pass between commission of the crime and commencement of the prosecution. Nor does the statute place any limits on the age of the victim either at the time a report sufficient to trigger the statute is made, or at the time criminal charges based on such a report are filed. Rather, a felony prosecution commenced within one year of a qualifying report is timely under the literal terms of

section 803(g)(2)(

A) even, indeed only, if the limitations period otherwise applicable under

section 800 or 801 “has expired.” The quoted phrase obviously ensures that the one-year period in

section 803(g)(1) does not override or otherwise conflict with sections 800 and 801 where the victim reports the crime to a qualifying law enforcement agency before the three-year or six-year period set forth in the latter provisions “has expired.” In this way, the limitations period in

section 803(g)—like other “tolling” and “extension” provisions in the same statute—serves to prolong, rather than shorten, the time in which a felony child molestation prosecution may be commenced. However, nothing in

section 803(

g) provides that the crime must be committed, or that the limitations period in

section 800 or 801 must expire, after January 1, 1994, in order for the extended one-year period to apply. The 1996 amendment left no doubt that

section 803(

g) applies even where the existing statute of limitations expired before January 1, 1994. As we have seen, certain Court of Appeal opinions of which the Legislature was presumably aware refused to apply

section 803(

g) in such cases even where criminal charges were filed within one year of the time the victim reported the underlying crime to law enforcement officials. (Ante, fn. 6.) This once-published line of authority reasoned that the 1994 law was at least ambiguous insofar as it reflected a legislative intent to “revive” prosecutions that were time-barred under sections 800 and 801 by the time

section 803(

g) was enacted. Based on the language of the 1996 amendment, the Legislature obviously sought to fill this perceived gap by providing that compliance with the one-year limitations period “revive[s]” the state’s ability to file felony charges in “any” action “barred by

Section 800 or 801,” regardless of whether the crime occurred “before, on, or after January 1, 1994,” the initial effective date of the statute. (§ 803(g)(3)(A), italics added.) Because it explicitly applies in prosecutions of all enumerated sex crimes which occurred at any time “before” January 1, 1994, including “any” crime otherwise “barred” by the statute of limitations,

section 803(

g) necessarily applies where, as here, the six-year period otherwise applicable under

section 800 had expired before January 1, 1994. In order to reach a contrary conclusion, we would have to read

section 803(

g) as applying to all covered sex-abuse crimes, regardless of when they occurred, except in cases in which the limitations period in

section 800 or 801 had expired before January 1, 1994. We decline such a tortured construction. The legislative history of the 1996 amendment confirms this view. Indeed, the Legislature was highly familiar with the various Court of Appeal opinions filed in 1995 and 1996 that declined to apply

section 803(

g) where “the previously applicable statute of limitations had expired prior to January 1, 1994 (the effective date of

Section 803(g)).” (Assem. Floor Analysis, Assem. Bill No. 2014 (1995-1996 Reg. Sess.) June 21, 1996, p. 1.) The legislative record identified these Court of Appeal decisions by name and original published citation, and summarized the statutory and constitutional analysis each used to reach this conclusion. (Id., pp. 1-2; Sen. Com. on Crim. Procedure, Analysis of Assem. Bill No. 2014 (1995-1996 Reg. Sess.) June 3, 1996, pp. 7-9.) According to the legislative record, the primary reason for amending

section 803(

g) in 1996 was to repudiate these Court of Appeal decisions insofar as they had construed the statute in such a restrictive manner. The 1996 amendment sought to “clarify,” through express “retroactivity” and “revival” provisions, that

section 803(

g) permitted charges to be filed within one year of the victim’s report, even where prosecution of the crime was otherwise time-barred before January 1, 1994. (Sen. Com. on Crim. Procedure, Analysis of Assem. Bill No. 2014 (1995-1996 Reg. Sess.) June 3, 1996, pp. 5-7; Sen. Floor Analysis, Assem. Bill No. 2014 (1995-1996 Reg. Sess.) June 3, 1996, pp. 2-4.) Finally, the Legislature considered and rejected the ex post facto concerns cited by some of the targeted Court of Appeal cases as a basis for not applying

section 803(

g) in a manner consistent with its underlying intent. Legislative analysts opined that a postcrime increase in the statute of limitations was not the type of criminal legislation prohibited under Collins, supra, 497 U.S. 37, even where the limitations period in existence at the time of the crime had already expired. (Assem. Floor Analysis, Assem. Bill No. 2014 (1995-1996 Reg. Sess.) June 21,1996, pp. 2-3; Assem. Com. on Public Safety, Analysis of Assem. Bill No. 2014 (1995-1996 Reg. Sess.) April 8, 1996, pp. 2-3.) Thus, consistent with allegations in the complaint,

section 803(

g) serves as an exception to

section 800 in the present case. We next consider the parties’ arguments concerning the constitutionality of this result. IV. Ex Post Facto Claim The People do not dispute an assumption made by defendant and the Court of Appeal that

section 803(

g) operates retroactively because it withdraws a basis for demurrer—expiration of the statute of limitations under

section 800—which defendant was entitled to assert before

section 803(

g) was enacted. (See Weaver v. Graham (1981) 450 U.S. 24, 31 [101 S.Ct. 960, 965, 67 L.Ed.2d 17] [defining retroactive law as “chang[ing] the legal consequences of acts completed before its effective date”]; Tapia v. Superior Court (1991) 53 Cal.3d 282, 288 [279 Cal.Rptr. 592, 807 P.2d 434] [same].) The People argue, however, that defendant and the Court of Appeal are mistaken to the extent they maintain that statutes of limitation are a form of penal legislation subject to ex post facto protection even where retroactive expansion of the statutory period occurs. We agree.

The ban on ex post facto legislation stems from the excesses of colonial rulers in using retrospective legislation as a means of political warfare and retribution. (Calder v. Bull (1798) 3 U.S. (3 Dall.) 386, 388-389 [1 L.Ed. 648, 649-650] (opn. of Chase, J.) (Calder); see Fellman, The Defendant’s Rights Today (1976) p. 99.) It ensures the citizenry has “fair warning” of the conduct proscribed by law and of the penalties imposed for violating those proscriptions. (Weaver v. Graham, supra, 450 U.S. 24, 28 [101 S.Ct. 960, 963-964]; Marks v.

United States (1977) 430 U.S. 188, 191 [97 S.Ct. 990, 992-993, 51 L.Ed.2d 260].) In this way, individuals are free to act in reliance on the law without fear that their conduct will be made punishable in a “vindictive” or “arbitrary” fashion after it has occurred. (Weaver v.

Graham, supra, 450 U.S. at p. 29 [101 S.Ct. at pp. 963-964].) Early in the nation’s history, the United States Supreme Court decided that the ex post facto clause applies only to criminal legislation as opposed to statutes which retroactively affect property, contract, or other interests protected in civil proceedings. (Calder, supra, 3 U.S. (3 Dall.) 386, 390-392 [1 L.Ed. 648, 650-651] (opn. of Chase, J.); 396-397 [1 L.Ed. at pp. 652-653] (opn. of Paterson, J.), 399-400 [1 L.Ed. at pp. 653-654] (opn. of Iredell, J.).) Moreover, in keeping with the original purpose of the framers of the Constitution, only certain criminal legislation is subject to ex post facto protection. (Beazell v.

Ohio (1925) 269 U.S. 167, 169-171 [46 S.Ct. 68, 68-69, 70 L.Ed. 216] (Beazell); Calder, supra, 3 U.S. (3 Dall.) at p. 390 [1 L.Ed. at p. 650] (opn. of Chase, J.).) According to Beazell, which summarized Justice Chase’s definition of ex post facto laws in Calder, “any statute which punishes as a crime

an act previously committed, which was innocent when done; which makes more burdensome the punishment for a crime, after its commission, or which deprives one charged with crime of any defense available according to law at the time when the act was committed, is prohibited as ex post facto. The constitutional prohibition and the judicial

interpretation of it rest upon the notion that laws, whatever their form, which purport to make innocent acts criminal after the event, or to aggravate an offense, are harsh and oppressive, and that the criminal quality attributable to

an act, either by the legal definition of the offense or by the nature or amount of the punishment imposed for its commission, should not be altered by legislative enactment, after the fact, to the disadvantage of the accused.” (Beazell, supra, 269 U.S. 167, 169-170 [46 S.Ct. 68, 68-69], italics added.) More recently, in Collins, supra, 497 U.S. 37, 39-40 [110 S.Ct. 2715, 2717-2718], a convicted sex offender challenged, as ex post facto, postcrime legislation that allowed a state court to summarily correct an unauthorized sentence on review of the judgment in his case, even though he would have been entitled to a new jury trial under the law in existence at the time of his crime.

In rejecting the claim, the United States Supreme Court subjected its ex post facto jurisprudence to close scrutiny, reviewing formulations of the principle from Calder, supra, 3 U.S. (3 Dall.) 386, through Beazell, supra, 269 U.S. 167, and into the late 20th century.

This review resulted in wholesale endorsement of “[t]he Beazell formulation [as] faithful to our best knowledge of the original understanding of the Ex Post Facto Clause.” (Collins, supra, 497 U.S. at p. 43 [110 S.Ct. at p. 2719].) The “Beazell formulation” was then distilled into a concise two-part test for use in Collins and future cases: “Legislatures may not retroactively alter the definition of crimes or increase the punishment for criminal acts.” (Ibid., italics added.) After articulating the controlling standard for resolving ex post facto challenges under the federal Constitution, Collins made clear that the two categories of impermissible retroactive legislation—redefining criminal conduct and increasing punishment—are exclusive.

This critical point was communicated in several different ways.

First, the two-part definition of ex post facto legislation was repeated throughout Collins in almost talismanic form. (497 U.S. at pp. 44 [110 S.Ct. at p. 2723] [the challenged statute “does not alter the definition of the crime of aggravated sexual abuse, of which [the defendant] was convicted, nor does it increase the punishment for which he is eligible as a result of that conviction”], 49 [110 S.Ct. at p. 2723] [approving a case that defined ex post facto laws solely in terms of “altering the definition of an offense or increasing a punishment”], 50 [110 S.Ct. at p. 2723] [disapproving a case that did not define ex post facto laws solely in terms of “alterations in ‘the legal definition of the offense’ or ‘the nature or amount of the punishment imposed for its commission’ ”].) Second, the high court criticized language in some of its own decisions defining the ex post facto prohibition more expansively to include any “procedural change” which deprives the defendant of “ ‘substantial protections’ ” or “ ‘substantial personal rights’ ” existing at the time of the crime. (Collins, supra, 497 U.S. at p. 45 [110 S.Ct. at pp. 2720-2721].) Collins explained that such language was misleading because, whether a retroactive criminal statute is deemed procedural or substantive, it contravenes the ex post facto clause only if it redefines criminal conduct or aggravates punishment. (Id., at pp. 45-46 [110 S.Ct. at pp. 2720-2721].) Collins also expressly overruled two prior decisions that used the ex post facto clause to invalidate state statutes which “ ‘ “alter[ed] the situation of a party to his disadvantage” ’ ” (id., at p. 47 [110 S.Ct. at pp. 2721]), but which fell into neither of the two prohibited categories. (Id. at pp. 47-52 [110 S.Ct. at pp. 2721-2724], overruling Kring v.

Missouri (1883) 107 U.S. 221 [2 S.Ct. 443, 27 L.Ed. 506] [postcrime change in law prevented capital defendant from asserting on retrial that he had been acquitted of first degree murder based on prior guilty plea to lesser offense of second degree murder]; Thompson v.

Utah (1898) 170 U.S. 343 [18 S.Ct. 620, 42 L.Ed. 1061] [postcrime reduction in the size of criminal juries].) Finally, Collins, supra, 497 U.S. 37, clarified that language in Beazell, supra, 269 U.S. 167, 169 [46 S.Ct. 68, 68], prohibiting postcrime deprivations of “any defense available according to law at the time when the act was committed,” should not be misread as creating a separate or third category of impermissible ex post facto legislation.

According to Collins, supra, 497 U.S. at page 50 [110 S.Ct. at page 2723], the quoted phrase “was linked [in Beazell, supra, 269 U.S. at pages 169-170 [46 S.Ct. at pages 68-69]] to the prohibition on alterations in ‘the legal definition of the offense’ or ‘the nature or amount of the punishment imposed for its commission.’ ” In other words, the only “defense[s]” that cannot be restricted or withdrawn for ex post facto purposes are those bearing on the “definition” or “elements” of the charged crime, or involving “an excuse or justification for the conduct underlying such a charge.” (Collins, supra, 497 U.S. at p. 50 [110 S.Ct. at p. 2723].) A statutory change in the legal effect of the postcrime passage of time does not implicate criminal conduct or punishment as required by Collins, supra, 497 U.S. 37.

As explained more fully in conjunction with defendant’s due process claim, post, statutes of limitation are an optional form of “legislative grace,” reflecting a pragmatic determination that the interests of the state are best served by forgoing prosecution in some cases. Such laws, including California’s criminal statutes of limitation, generally seek to protect both the judicial system and the defendant from the burden of litigating claims after a specified time has passed, and after relevant evidence is presumably less reliable or no longer available.

As indicated by the authorities cited in footnotes 19 and 20, ante, the statute of limitations is often said to work in an “arbitrary” or “mechanical” fashion to insulate from prosecution even those individuals whose conduct otherwise satisfied all elements of a penal statute, and who were otherwise subject to criminal punishment, at the time the conduct occurred. Here, for instance, the definition of the charged crime has not changed over time. No material revision in the language of

section 288(

a) has occurred between 1984, when the crime allegedly took place, and the present time. Indeed,

section 288 was enacted in 1901, and the elements defining criminal conduct under what is now subdivision (

a) have remained the same for decades. (People v. Martinez (1995) 11 Cal.4th 434, 442-446 & fns. 5, 7, 8 [45 Cal.Rptr.2d 905, 903 P.2d 1037] (Martinez); People v. Scott (1994) 9 Cal.4th 331, 342-343 & fn. 5 [36 Cal.Rptr.2d 627, 885 P.2d 1040].) The crime has long involved “ ‘any touching’ of an underage child accomplished with the intent of arousing the sexual desires of either the perpetrator or-the child.” (Martinez, supra, 11 Cal.4th at p. 452.) There also has been no relevant change in the punishment prescribed by

section 288(a). Now, as in 1984, a base term of imprisonment of “three, six, or eight years” may be imposed where conviction under the statute occurs. (Ibid.) Given the unchanged nature of

section 288(

a) since the time defendant allegedly molested Jessica F., we see no basis on which to conclude that the limitations period in

section 803(g) “alter[s] the definition of the [charged] crime” or “increase[s] the [applicable] punishment.” (Collins, supra, 497 U.S. 37, 44 [110 S.Ct. 2715, 2720-2721].) Nevertheless, defendant insists

section 803(

g) impermissibly deprives him of a “ ‘defense available according to law at the time when the act was committed.’” (Collins, supra, 497 U.S. 37, 42 [110 S.Ct. 2715, 2719], quoting Beazell, supra, 269 U.S. 167, 169 [46 S.Ct. 68, 68].) Defendant observes that when the crime allegedly occurred,

section 800 provided immunity from prosecution in the event prosecution did not commence within six years of the charged crime. Alluding to reasoning used by the instant Court of Appeal and other state court cases on which it relied, defendant insists expiration of the limitations period in

section 800 provided him with a complete defense to criminal liability and punishment which could not later be withdrawn under

section 803(

g) consistent with ex post facto guarantees. (See Bunn, supra, 53 Cal.App.4th 227, 232-239; Lynch, supra, 33 Cal.App.4th 1223, 1226-1228.) We disagree. As we have explained, the ex post facto clause is concerned exclusively with “the criminal quality attributable to

an act’ as evidenced “either by the legal definition of the offense or by the nature or amount of the punishment” at the time it occurs. (Beazell, supra, 269 U.S. 167, 170 [46 S.Ct. 68, 68-69], italics added.) The primary purpose of the constitutional guarantee is to ensure that the consequences of a particular course of conduct can be meaningfully assessed in advance, without fear that the rules of criminality and punishment will later change. (Weaver v. Graham, supra, 450 U.S. 24, 28-29 [101 S.Ct. 960, 963-964]; Marks v.

United States, supra, 430 U.S. 188, 191 [97 S.Ct. 990, 992-993].) For this reason, Collins made clear that ex post facto protection extends only to “defense[s]” bearing on the “definition” and “elements” of proscribed conduct, or involving “excuse or justification” for its commission. (497 U.S. 37, 50 [110 S.Ct. 2715, 2723].) Application of

section 803(

g) to defendant’s case in no way violates these principles. The

section makes no change in the' act or intent elements which the prosecution must prove beyond a reasonable doubt to obtain a conviction under

section 288(a), the circumstances which can be used by the defendant to show no lewd touching of an underage child occurred under

section 288(a), or the range of state prison sentences available as punishment under

section 288(a).

Section 803(

g) simply provides that where the victim has waited to report a violation of

section 288(

a) or other enumerated sex crime to a law enforcement agency, and where the limitations period has otherwise expired, there is an additional one-year period in which a criminal complaint may be filed after a qualifying report is made.

Section 803(

g) regulates the time at which child sexual abuse defined and punished elsewhere in the Penal Code may be charged, but it does not impermissibly withdraw a “defense” as that term of art is used for ex post facto purposes in Collins, supra, 497 U.S. 37, 50 [110 S.Ct. 2715, 2723].

In a related vein, defendant argues that even if the state can file charges based on a postcrime “extension” of the statutory period that takes effect before the statute of limitations in existence at the time of the crime expires, ex post facto principles do not permit postcrime “revivals” of criminal prosecutions that were time-barred before the new longer statute of limitations was enacted. Under this view, since the six-year period set by

section 800 had ostensibly run before

section 803(

g) was enacted and before a complaint charging lewd conduct was filed against defendant, the People could not subsequently use

section 803(

g) to prosecute defendant in a timely fashion consistent with ex post facto guarantees. Like the Court of Appeal in this case, defendant insists such a conclusion is dictated by Falter, supra, 23 F.2d 420, and its progeny. We disagree. In Falter, three defendants were jointly indicted, tried, and convicted for conspiracy to defraud the United States by means of a protracted scheme to buy surplus military goods at fraudulently induced, below-market prices.

Writing for a unanimous panel of the Second Circuit Court of Appeals, Judge Learned Hand addressed the defendants’ main claim on appeal at length, and found sufficient evidence of fraudulent activity within the meaning of the federal statute under which charges had been filed. (23 F.2d at pp. 423-425.) Towards the end of the opinion, a series of other legal attacks on the judgment were rejected in relatively succinct terms.

Pertinent here is the defendants’ claim in Falter that prosecution of their conspiracy was barred under the applicable statute of limitations and the ex post facto clause of the federal Constitution. On the latter issue, the Falter court observed that at the time the fraudulent scheme occurred, in late 1919 through early 1920, the applicable statute of limitations permitted commencement of the prosecution within three years of the crime.

In November 1921, before the three-year period expired with respect to defendants’ crime, the statute of limitations was amended to allow prosecution within a six-year period. (Falter, supra, 23 F.2d at p. 425.) Without describing the precise nature of the constitutional claim, Falter rejected defendants’ suggestion that any adverse “change [in the statute of limitations] after the commission of the crime, and while the [original] time [period] is running,” constitutes a violation of the ex post facto clause. (Falter, supra, 23 F.2d p. 425.) The court cited language in Beazell, supra, 269 U.S. 167, 170 [46 S.Ct. 68, 68-69], indicating that the ex post facto clause only protects against unfavorable retroactive changes in the

definitions of crime and punishment, and found nothing “ ‘harsh and oppressive’ ” in allowing the state to benefit from a postcrime increase in the applicable statutory period. (Falter, supra, at p. 425.) Falter noted that a 19th century New Jersey court had reached a different result where the statute of limitations existing at the time of the crime “had once run” before an amendment expanding the period was enacted. (Ibid., citing Moore v.

State (E. & A. 1881) 43 N.J.L. 203.) As emphasized by defendant in the present case, Falter then purported to distinguish, in colorful terms, between permissible postcrime “extensions” of a criminal statute of limitations and impermissible postcrime “revivals.” Defendant recognizes that no decision of the United States Supreme Court or this court has used the foregoing passage from Falter to decide an ex post facto question of the sort raised here. Hence, we are not compelled by Falter to find a constitutional violation insofar as

section 803(

g) applies, on its face, to child molestation cases in which

section 800 or 801 had expired and no criminal charges were filed before January 1, 1994. On the other hand, defendant asks that we embrace the principles expressed by Falter in footnote 23, ante, and adopt such reasoning as our own. Defendant correctly notes that many federal and state courts have cited the relevant passage with approval over the years, as discussed further below. However, Falter, supra, 23 F.2d 420, and its progeny are not persuasive authority for invalidating

section 803(

g) on ex post facto grounds. Preliminarily, the distinction drawn in Falter between permissible and impermissible postcrime expansions in the statute of limitations was unnecessary to the decision in that case.

There was no question in Falter that the three-year limitations period in existence at the time of the conspiracy “had not run” at the time the statute was amended and the new six-year period took effect. (23 F.2d at p. 425.) At most, the defendants could be understood as raising an ex post facto challenge based on a postcrime statutory change that increased the time for filing conspiracy charges “while the [three-year] time [period] is running.” (Ibid.) The Falter court' correctly rejected such a constitutional challenge based on principles set forth in Beazell, supra, 269 U.S. 167.

Any question whether the result might have been different if the original limitations period “had once run” prior to amendment of the statute was not pending before the court in Falter, supra, 23 F.2d at page 425. However, the primary reason we find no ex post facto violation here based on dictum in Falter, or on any case cited therein, is that such a result would be inconsistent with Beazell, supra, 269 U.S. 167, 169-170 [46 S.Ct. 68, 68-69], and its modem counterpart, Collins, supra, 497 U.S. 37, 43 [110 S.Ct. 2715, 2719-2720].

Statutes regulating the time at which a future criminal prosecution may be filed do not implicate the manner in which criminal conduct is defined and punished at the time it occurs—the sole concern of the ex post facto clause.

Thus, contrary to what Falter, supra, 23 F.2d 420, 425, suggested, it makes no difference for ex post facto purposes whether a postcrime change in the statute of limitations “revive[s] a prosecution already dead” or “give[s] it a longer lease of life.” In neither case does the new expanded statute of limitations “retroactively alter the definition of crimes or increase the punishment for criminal acts” within the meaning of Collins, supra, 497 U.S. 37, 43 [110 S.Ct. 2715, 2719]. (See Retroactivity and Childhood Sexual Abuse, supra, 28 Pacific L.J. 796, 802 [section 803(

g) survives ex post facto challenge where prosecution was time-barred before statute was enacted]; Time’s No Bar to Revival, supra, 22 Ind. L.Rev. 989, 1009-1017 [same general conclusion regarding retroactive expansion of criminal statutes of limitation].) We recognize that Falter, supra, 23 F.2d 420, 425-426, has been cited with approval by courts in other jurisdictions and in this state, often in cases involving statutes increasing the time for prosecuting child sexual abuse based on acts committed before the statutory change.

As noted by the People, however, the vast majority of these decisions reject an ex post facto claim under circumstances similar to those at issue in Falter—unfavorable postcrime change in the statute of limitations involving defendants against whom the limitations period existing at the time of the crime had not run when the amendment took effect. The conclusion reached by the cases cited in footnote 25, ante, is not inconsistent with our view that application of

section 803(

g) to defendants whose prosecutions were time-barred before January 1, 1994, does not offend ex post facto guarantees. Not surprisingly, one of the more recent and thoughtful cases in this group seems to depart from Falter, supra, 23 F.2d 420, 425-426, and questions whether any retroactive change in the statute of limitations implicates criminal conduct and punishment under Collins, supra, 497 U.S. 37.

It appears that few courts have relied on the reasoning of Falter, supra, 23 F.2d 420, 425-426, to decide the precise question raised by defendant here, namely, whether federal ex post facto principles bar the Legislature from increasing the time for filing criminal charges where the defendant achieved statutory repose before the limitations period was so changed. Our research discloses that courts in no fewer than five states have found a constitutional violation under such circumstances.

In particular, this result has been reached in at least nine opinions—five from other states, and four from California, including two cases involving

section 803(

g) and followed by the Court of Appeal here. However, most of these decisions predate Collins, supra, 497 U.S. 37, while others do not follow Collins insofar as it extends ex post facto protection only to laws which retroactively redefine crimes or increase punishment. Because the cases cited in footnotes 27 and 28, ante, are based on an impermissibly broad understanding of ex post facto principles, they provide no meaningful support for defendant’s claim. We conclude that

section 803(

g) is not an ex post facto law insofar as it applies, on its face, to the instant case. The following decisions are disapproved to the extent they are inconsistent with this view: Bunn, supra, 53 Cal.App.4th 227; Lynch, supra, 33 Cal.App.4th 1223; People v. Gordon, supra, 165 Cal.App.3d 839; Sobiek v. Superior Court, supra, 28 Cal.App.3d 846. V. Due Process Claim Defendant argues here, as below, that once the six-year period in

section 800 had expired as to the charged crime, he could not be prosecuted under

section 803(g), as thereafter adopted, consistent with federal due process guarantees. (U.S. Const., 5th & 14th Amends.) He alludes to substantive due process principles applied in civil cases to ensure that “vested” property rights are not retroactively impaired in an irrational or arbitrary manner. (See generally, In re Marriage of Bouquet (1976) 16 Cal.3d 583, 591-592 [128 Cal.Rptr. 427, 546 P.2d 1371].) In defendant’s view,

section 803(

g) deprives criminal defendants who had achieved statutory repose before January 1, 1994, of an analogous, constitutionally protected interest. The People vigorously disagree. They observe that the United States Supreme Court has never acknowledged a criminal defendant’s fundamental interest, protected by the due process clauses, in retaining the benefit of an already expired statute of limitations against subsequent attempts to amend the time at which charges may be filed. According to the People, no decision of any court supports defendant’s contrary view. We agree with the People that defendant is essentially asking this court to invalidate

section 803(

g) by recognizing a new federal constitutional right based on the assumption that criminal defendants have a fundamental “right to repose,” once such repose is achieved under the statute of limitations then in effect. For reasons we explain, the high court all but rejected this view in Chase, supra, 325 U.S. 304. Though defendant virtually ignores this significant case, it supports our decision to reject his claim.

In Chase, the plaintiff filed suit in Minnesota state court in 1937 to recover the cost of unregistered securities that had allegedly been sold in 1929 in violation of Minnesota statutory and common law. The defendant, a corporation, argued in the trial court that the action was time-barred, and apparently asserted, among other things, the six-year statute of limitations generally applicable to actions founded upon liabilities created by statute.

The plaintiff disagreed, claiming that the defendant had withdrawn from the state in 1931 and that the running of the statutory period had been suspended during its absence. The trial court rejected the statute of limitations claim on the ground urged by the plaintiff, found an illegal sale of securities under the regulatory scheme, and did not rule on the common law claims. Judgment was entered in the plaintiff’s favor. On appeal, the Minnesota Supreme Court determined that the statute of limitations had not been tolled due to the defendant’s absence from the state.

The judgment was reversed and, in January 1941, the case was remanded for further proceedings not inconsistent with the latter decision. (Chase, supra, 325 U.S. at p. 306 [65 S.Ct. at pp. 1138-1139].) While the case was pending in the trial court, the Minnesota Legislature amended the regulatory scheme and included, for the first time, a specific statute of limitations applicable to actions arising thereunder.

The effect of the statutory change, which became operative July 1941, was “to abolish any defense that [the defendant] might otherwise have made under the [more generalized] statutes of limitation” which had previously governed the challenged sale or which had been applied in its favor in the case. (Chase, supra, 325 U.S. at p. 308 [65 S.Ct. at p. 1139].) On remand in the trial court, the defendant argued, among other things, that the new statute of limitations did not apply and that the plaintiff’s action was time-barred under prior law.

The defendant argued alternatively that to the extent amendment of the regulatory scheme had retroactively expanded the applicable limitations period or withdrawn a statute of limitations bar it had previously been entitled to assert on its behalf, the defendant was deprived of its property in violation of the due process clause of the Fourteenth Amendment. The foregoing claims were rejected by the trial court, which again entered judgment in the plaintiff’s favor.

The Minnesota Supreme Court affirmed. (Chase, supra, 325 U.S. at pp. 308-309 [65 S.Ct. at pp. 1139-1140].) The defendant renewed its due process attack on the new statute of limitations in the United States Supreme Court. After noting that “substantial federal questions” had been raised, the court rejected the claim. (Chase, supra, 325 U.S. at p. 311 [65 S.Ct. at pp. 1140-1141].) Chase began by summarizing the holding of Campbell v.

Holt (1885) 115 U.S. 620 [6 S.Ct. 209, 29 L.Ed. 483] (Campbell), the decision on which the Minnesota Supreme Court had relied in rejecting the defendant’s federal constitutional claim. “In [Campbell], this Court held that where lapse of time has not invested a party with title to real or personal property, a state legislature, consistently with the Fourteenth Amendment, may repeal or extend a statute of limitations, even after right of action is barred thereby, restore to the plaintiff his remedy, and divest the defendant of the statutory bar.” (Chase, supra, 325 U.S. 304, 311-312 [65 S.Ct. 1137, 1141].) The Chase court recognized that “some state courts have not followed [the foregoing rule] in construing provisions of their constitutions similar to the due process clause.” (Id., at p. 312 [65 S.Ct. at p. 1141].) Chase also acknowledged “some criticisms” of Campbell, supra, 115 U.S. 620, “in legal literature.” (325 U.S. at p. 313 [65 S.Ct. at p. 1142].) Nevertheless, the court refused to overrule Campbell, supra, 115 U.S. 620, or otherwise depart from its “essential holding” that federal due process principles do not preclude the Legislature from making retroactive changes in the applicable limitations period detrimental to the defense. (Chase, supra, 325 U.S. 304, 315 [65 S.Ct. 1137, 1143].) In so doing, the court declined to reexamine or “settle” the ancient debate underlying Campbell as to whether limitation periods are prescriptive in nature such that their expiration destroys the attendant legal “right,” or whether they merely affect the “remedy” for enforcing such a right. (Chase, supra, at p. 313 [65 S.Ct. at p. 1142] .) Instead, Chase relied on a more pragmatic view of the statute of limitations that had evolved since Campbell was decided, namely, that such laws are instruments of “public policy” existing at the will of the legislature, and that their shelter has never been viewed as a “ ‘fundamental’ right.” (Id., at p. 314 [65 S.Ct. at p. 1142].) Chase then denied relief to the defendant under the United States Constitution for the following reasons: “The Fourteenth Amendment does not make

an act of state legislation void merely because it has some retrospective operation. What it does forbid is taking of life, liberty or property without due process of law. Some rules of law probably could not be changed retroactively without hardship and oppression, and this whether wise or unwise in their origin.

Assuming that statutes of limitation, like other types of legislation, could be so manipulated that their retroactive effects would offend the Constitution, certainly it cannot be said that lifting the bar of a statute of limitation so as to restore a remedy lost through mere lapse of time is per se an offense against the Fourteenth Amendment. Nor has the [defendant] pointed out special hardships or oppressive effects which result from lifting the bar in this class of cases with retrospective force.

This is not a case where [the defendant’s] conduct would have been different if the present rule had been known and the change foreseen. [The defendant] does not say, and could hardly say, that it sold unregistered stock depending upon a statute of limitation for shelter from liability. The nature of the defenses shows that no course of action was undertaken by [the defendant] on the assumption that the old rule would be continued.

When the action was commenced, [the defendant] no doubt expected to be able to defend by invoking Minnesota public policy that lapse of time had closed the courts to the case, and its legitimate hopes have been disappointed. But the existence of the policy at the time the action was commenced did not, under the circumstances, give the [defendant] a constitutional right against change of policy before final adjudication.

Whatever grievance [the defendant] may have at the change of policy to its disadvantage, it had acquired no immunity from this suit that has become a federal constitutional right.” (Chase, supra, 325 U.S. at pp. 315-316 [65 S.Ct. at p. 1143] .) The holding of Chase—that no constitutionally protected interest arises once a statute of limitations has run, and that such protection can be retroactively withdrawn consistent with due process—has been reaffirmed by the high court in subsequent cases. (See Plaut v.

Spendthrift Farm, Inc. (1995) 514 U.S. 211, 229 [115 S.Ct. 1447, 1458, 131 L.Ed.2d 328] [noting that statutes of limitation “can be extended, without violating the Due Process Clause, after the cause of the action arose and even after the statute itself has expired”]; Electrical Workers v.

Robbins & Myers, Inc. (1976) 429 U.S. 229, 243 [97 S.Ct. 441, 450, 50 L.Ed.2d 427] [rejecting claim that “Congress was without constitutional power to revive, by enactment, an action which, when filed, is already barred by the running of a limitations period”].) We see no meaningful basis on which to distinguish the six-year period in

section 800 from the statute of limitations discussed in Chase, supra, 325 U.S. 304. That this case involves a criminal, rather than a civil, statute of limitations is not such a persuasive distinction. No provision of the United States Constitution explicitly confers upon criminal defendants a “right to repose” by virtue of the length of time between commission of the crime and commencement of the prosecution. (See Doggett v.

United States (1992) 505 U.S. 647, 667-669 [112 S.Ct. 2686, 2699, 120 L.Ed.2d 520] (dis. opn. of Thomas, J.) (Doggett) [discussing Sixth Amendment right to speedy trial].) Nor does the federal Constitution itself prescribe a fixed or certain time in which indictment must occur after the crime. (See Adlestein, Conflict of the Criminal Statute of Limitations With Lesser Offenses at Trial (1995) 37 Wm. & Mary L.Rev. 199, 250 & fn. 224 (The Criminal Statute of Limitations).) It is well settled that, aside from procedural due process concerns arising under the Fifth Amendment and involving claims of actual prejudice at trial (see discussion, post), “the applicable statute of limitations ... is . . . the primary guarantee against bringing overly stale criminal charges.” (United States v.

Ewell (1966) 383 U.S. 116, 122 [86 S.Ct. 773, 777, 15 L.Ed.2d 627]; accord, United States v. Lovasco (1977) 431 U.S. 783, 789 [97 S.Ct. 2044, 2048, 52 L.Ed.2d 752] (Lovasco); see United States v. Gouveia (1984) 467 U.S. 180, 192 [104 S.Ct. 2292, 2299-2300, 81 L.Ed.2d 146]; United States v.

MacDonald, supra, 456 U.S. 1, 7-8 [102 S.Ct. 1497, 1501-1502]; Marion, supra, 404 U.S. 307, 322 [92 S.Ct. 455, 464].) Such statutes provide a measure of predictability “by specifying a limit beyond which there is an irrebuttable presumption that a defendant’s right to a fair trial would be prejudiced.” (Marion, supra, 404 U.S. at p. 322 [92 S.Ct. at p. 464], fn. omitted.) However, criminal statutes of limitation are no less

an act of “policy” or “grace” than their counterparts in civil cases. (Chase, supra, 325 U.S. 304, 314 [65 S.Ct. 1137, 1142].) The high court has made clear that such laws reflect “legislative assessments of relative interests of the State and the defendant in administering and receiving justice.” (Marion, supra, 404 U.S. 307, 322 [92 S.Ct. 455, 464].) As in civil cases, such interests include both societal repose and the protection of individuals whose means of defense might be impaired by the passage of time. (Ibid.; see Cowan v.

Superior Court, supra, 14 Cal.4th 367, 374-375 [identifying the “policy considerations” underlying California’s criminal statutes of limitation and finding none to “prevent a defendant from waiving the statute of limitations in this situation”].) Some states have traditionally provided no statutes of limitation in criminal cases, while many states, including California, do not limit the time for prosecuting certain crimes. (E.g., § 799; see The Criminal Statute of Limitations, supra, 37 Wm. & Mary L.Rev. 199, 250, fn. 223; A Model for Reform, supra, 65 Wash.

L.Rev. 189, 191 & fns. 13, 14; A Time for Reform, supra, 80 J. Crim. L. & Criminology 842, 845-846.) Criminal statutes of limitation appear no more rooted in the Constitution or the traditions underlying the American legal system than their civil counterparts. It follows that “[w]hatever grievance [the defense in a criminal case] may have at the change of policy to its disadvantage, it had acquired no immunity from [prosecution] that has become a federal constitutional right.” (Chase, supra, 325 U.S. 304, 316 [65 S.Ct. 1137, 1143].) Under no existing

interpretation of substantive due process principles is the Legislature without power to limit or deny a statute of limitations claim in a criminal case after it has been acquired. In light of Chase, supra, 325 U.S. 304, a contrary conclusion is foreclosed. (See State v. Cookman, supra, 920 P.2d 1086, 1095-1097 (conc. & dis. opn. of Gillette, J.) [amendment increasing time to file child molestation charges does not offend due process insofar as it applies to defendants who achieved repose before statutory period was changed]; Retroactivity and Childhood Sexual Abuse, supra, 28 Pacific L.J. 796, 802-804 [section 803(

g) does not offend substantive due process guarantees]; Time’s No Bar to Revival, supra, 22 Ind. L.Rev. 989, 1014-1019 [same general conclusion regarding retroactive expansion of criminal statutes of limitation].) The sole authority cited in support of defendant’s federal due process theory are cases resolving analogous claims under the ex post facto clause, as discussed earlier in the opinion. We note that in defendant’s brief on the merits in this court, the claim that

section 803(

g) impairs a “vested” right in violation of substantive due process guarantees is inextricably intertwined with his ex post facto claim. Both arguments share the same headings and textual discussion, and are accompanied by the same case citations. However, as we have previously explained, the reasoning underlying Falter, supra, 23 F.2d 420, and other cases on which defendant relies is flawed.

They rest on an expansive view of the ex post facto clause which was disapproved in Collins, supra, 497 U.S. 37, 45-52 [110 S.Ct. 2715, 2720-2724], Under Collins, the legislative branch is not prohibited from retroactively expanding a criminal statute of limitations, because neither the definition of criminal conduct nor an increase in punishment is involved. Statutes governing the time at which a future criminal action may be filed are not enactments on which defendants may reasonably rely in deciding whether to commit

an act otherwise defined as criminal and subject to punishment under the law in existence at the time. While defendant focuses for due process purposes on the time at which the limitations period in

section 800 or 801 expires, nothing compels or authorizes this court to find that he acquired a “vested” or “fundamental” right under the United States Constitution with which

section 803(

g) impermissibly interferes. We decline to invalidate

section 803(

g) based on a new constitutional right which, under Chase, supra, 325 U.S. 304, the high court has itself refused to embrace. Of course, substantive due process principles preclude arbitrary and capricious legislation even where no fundamental right or liberty interest is at stake. (See Reno v. Flores, supra, 507 U.S. 292, 305 [113 S.Ct. 1439, 1448-1449] [“The impairment of a lesser interest . . . demands no more than a ‘reasonable fit’ between governmental purpose . . . and the means chosen to advance that purpose”].) Contrary to what defendant claims,

section 803(

g) is not unconstitutional under this deferential standard insofar as the statute “revives” previously time-barred prosecutions. Indeed, as the legislative history suggests, the statute is based on the assumption that past and future sex crimes against children, even though subject to corroboration by independent evidence, would otherwise go unpunished given the difficulty young victims experience remembering and reporting such events, and their emotional vulnerability at the hands of adult perpetrators, including those in positions of trust.

The means chosen by the Legislature—allowing prosecution within one year of the official report, inserting express retroactivity and revival provisions, and requiring independent corroboration— seem particularly well suited to addressing the serious concerns underlying

section 803(g). For all the foregoing reasons, we reject defendant’s substantive due process challenge. Finally, defendant suggests that use of

section 803(

g) to provide an additional one-year period in which to file child molestation charges where the six-year period in

section 800 had expired before January 1, 1994, violates his right to a fair trial under the Fifth Amendment of the United States Constitution. The implication seems to be that, by allowing indictment based on acts committed before January 1, 1988,

section 803(

g) creates an unacceptable risk that the ability to contest the charge will be impaired by the passage of time. According to defendant, such a result is “fundamentally unfair” and offends procedural due process guarantees. (Lovasco, supra, 431 U.S. 783, 796 [97 S.Ct. 2044, 2051-2052]; see Medina v. California (1992) 505 U.S. 437, 443 [112 S.Ct. 2572, 2576, 120 L.Ed.2d 353].) In Lovasco, the defendant was charged in federal court with possessing and selling firearms that had been stolen from the United States mails about 18 months earlier.

Although the charges were evidently not time-barred as a statutory matter, the defendant moved to dismiss the indictment on grounds of unreasonable prejudicial delay. At the ensuing hearing, the defense presented evidence that the prosecution had acquired most of its information in the case by the time a postal inspector’s report was prepared one month after the crime. The defendant also established that two witnesses who could have been called on his behalf at trial had since died.

On rebuttal, the prosecution explained that the investigation continued even after the postal report was prepared in order to determine whether the weapons had been supplied by defendant’s son, who handled mail at the location from which they had apparently been stolen. Based on evidence adduced at the hearing, the district court granted the motion to dismiss. The Eighth Circuit Court of Appeals affirmed. The court did not question the prosecution’s stated reason for deferring indictment, namely, to await additional investigation and to determine whether other participants could be linked to the crime.

Nevertheless, the ensuing delay was deemed unreasonable since it resulted in the loss of testimony favorable to the defense. In reaching this conclusion, the appellate court basically adopted the defendant’s view that “due process bars prosecution whenever a defendant suffers prejudice as a result of preindictment delay.” (Lovasco, supra, 431 U.S. at p. 789 [97 S.Ct. at p. 2048].) The United States Supreme Court reversed.

Lovasco began by reaffirming the basic principle that due process plays “a limited role” in protecting against “oppressive” preaccusation delay even where no statute of limitations has run. (431 U.S. at p. 789 [97 S.Ct. at p. 2048].) The high court confirmed that “proof of actual prejudice” to the defense is necessary to prevail on such a constitutional claim. (Ibid.) However, the lower courts erred in Lovasco insofar as they assumed that a showing of prejudice was sufficient in this context.

The high court made clear that the due process inquiry contemplated by Lovasco, and the cases on which it relied, also requires consideration of “the reasons for the delay.” (Id., at p. 790 [97 S.Ct. at p. 2049].) Lovasco explained that the latter requirement is not satisfied where indictment is postponed after “probable cause” of defendant’s involvement in a crime appears, or even after evidence sufficient to prove his guilt “beyond a reasonable doubt” is obtained. (431 U.S. at pp. 791-792 [97 S.Ct. at pp. 2049-2050].) Rather, the court held that prejudicial preaccusation delay offends “the Due Process Clause of the Fifth Amendment” when undertaken “solely ‘to gain tactical advantage over the accused.’ ” (Id., at p. 795 [97 S.Ct. at p. 2051], citing Marion, supra, 404 U.S. 307, 324 [92 S.Ct. 455, 465].) For numerous reasons that need not be repeated here, the court explained that a contrary rule could hamper legitimate criminal investigations and unduly interfere with nuanced charging decisions beneficial to both the accused and the administration of justice.

Lovasco declined to describe “in the abstract the circumstances in which preaccusation delay would require dismissing prosecutions,” noting that the constitutional rule adopted therein could not be applied outside “the particular circumstances of individual cases.” (431 U.S. at pp. 796-797 [97 S.Ct. at p. 2052].) However, based on the factual record that had been developed in Lovasco, the court concluded that it was not “fundamentally unfair” to require the defendant to stand trial. (Id., at p. 796 [97 S.Ct. at p. 2052].) Notwithstanding any loss of evidence the defense may have sustained, the record showed only that the government engaged in legitimate efforts to discern the full scope of the criminal enterprise during the 18-month period before charges were filed.

Contrary to what defendant seems to imply, nothing in Lovasco or the due process principles on which it relied warrants wholesale invalidation of

section 803(g), regardless of when the charged crime occurred or when the statutory period in

section 800 or 801 otherwise expires. As we have seen, prosecutors have wide latitude in conducting criminal investigations and determining whether and when indictments should be filed. Such discretionary decisions offend the United States Constitution only where unfair tactics or improper motives are involved, and where the defendant’s ability to refute the charge is materially damaged as a result.

As Lovasco recognized, no court can make such a determination “in the abstract,” without considering “the particular circumstances of [the] individual case[ ].” (431 U.S. 783, 796-797 [97 S.Ct. 2044, 2052].) Because the claim is not “ripe for adjudication” in the present case, we express no opinion on whether, by analogy to principles set forth in Lovasco, defendant’s procedural due process rights have been violated by the 12-year lapse between commission of the alleged crime and the filing of the complaint. (431 U.S. at p. 789 [97 S.Ct. at p. 2048].) We hold only that, under existing

interpretations of the Fifth Amendment, there is no basis on which to facially invalidate

section 803(g), either on the ground its one-year limitations period leads to excessive charging delays, or on the ground.

section 803(

g) applies even where the six-year period in

section 800 “has expired.” VI. Disposition

Section 803(

g) is not unconstitutional on any ground asserted by defendant. The judgment of the Court of Appeal is reversed. George, C. J., Werdegar, J., and Chin, J., concurred. All further statutory references are to the Penal Code except as otherwise stated.

Section 800 states: “Except as provided in

Section 799, prosecution for an offense punishable by imprisonment in the state prison for eight years or more shall be commenced within six years after commission of the offense.”

Section 801 states: “Except as provided in Sections 799 and 800, prosecution for an offense punishable by imprisonment in the state prison shall be commenced within three years after commission of the offense.” Increases by other states in the statutory time for filing criminal charges in child sexual abuse cases, as well as the policies underlying such changes, are well documented in recent legal writings.

section 803(

g) which took effect January 1, 1994, read in full as follows: “Notwithstanding any other limitation of time described in [section 799 et seq.], a criminal complaint may be filed within one year of the date of a report to a law enforcement agency by a person of any age alleging that he or she, while under the age of 18 years, was the victim of a crime described in

Section 261 [rape], 286 [sodomy], 288 [lewd conduct], 288a [oral copulation], 288.5 [continuous sexual abuse], 289 [sexual penetration by foreign object], or 289.5 [fleeing sex offender]. This subdivision shall apply only if both of the following occur: “

(1) The limitation period specified in

Section 800 or 801 has expired. “

(2) The crime involved substantial sexual conduct, as described in subdivision (

b) of

Section 1203.066, excluding masturbation which is not mutual, and there is independent evidence that clearly and convincingly conoborates the victim’s allegation. No evidence may be used to corroborate the victim’s allegation which would otherwise be inadmissible during trial. Independent evidence shall not include the opinions of mental health professionals.” (Stats. 1993, ch. 390, § 1.) (People v.

section 803(g); Lynch, supra, 33 Cal.App.4th 1223.) (See § 3 [stating no provision of the Penal Code “is retroactive, unless expressly so declared”]; People v. Hayes (1989) 49 Cal.3d 1260, 1274 [265 Cal.Rptr. 132, 783 P.2d 719] [stating basic rule of statutory construction that new statutes are “generally presumed to operate prospectively absent an express declaration of retroactivity or a clear and compelling implication that the Legislature intended otherwise"]; Evangelatos v.

(People v. Regules (Cal.App.), review granted November 16, 1995, on April 24, 1997, review dismissed in light of intervening amendments to

section 803(g).) As a result of the 1996 amendment, language imported wholesale from the original version of

section 803(

g) was reorganized into newly configured subsections (1) and (2), as follows: “

(1) Notwithstanding any other limitation of time described in [section 799 et seq.], a criminal complaint may be filed within one year of the date of a report to a law enforcement agency by a person of any age alleging that he or she, while under the age of 18 years, was the victim of a crime described in

Section 261, 286, 288, 288a, 288.5, 289, or 289.5. “

(2) This subdivision applies only if both of the following occur: “(

A) The limitation period specified in

Section 800 or 801 has expired. “(

B) The crime involved substantial sexual conduct, as described in subdivision (

b) of

Section 1203.066, excluding masturbation that is not mutual, and there is independent evidence that clearly and convincingly corroborates the victim’s allegation. No evidence may be used to corroborate the victim’s allegation that otherwise would be inadmissible during trial. Independent evidence does not include the opinions of mental health professionals.” (Stats. 1996, ch. 130, § 1.) Language included for the first time in

section 803(

g) as a result of the 1996 amendment was placed in subsection (3), as follows: “(3)(

A) Effective July 1, 1997, this subdivision applies to a cause of action arising before, on, or after January 1, 1994, the effective date of this subdivision, and if the complaint is filed within the time period specified in this subdivision, it shall revive any cause of action barred by

Section 800 or 801. “(

B) Effective January 1, 1997, through June 30, 1997, this subdivision applies to a cause of action arising before, on, or after January 1, 1994, the effective date of this subdivision, and it shall revive any cause of action barred by

Section 800 or 801 if either of the following occurs: “(

i) The complaint is filed within the time period-specified in this subdivision!, or] “(ii) The victim made the report required by this subdivision to a law enforcement agency between January 1, 1994, and January 1, 1997, and a complaint was not filed within the time period specified in this subdivision or was filed within the time period but was dismissed, but a complaint is filed or refiled on or before June 30, 1997.” (Stats. 1996, ch. 130, § 1.) We note that the 1996 amendment also inserted a special savings clause, appearing in former

section 803(g)(3)(B)(ii), and quoted in full in the preceding footnote. This provision gave prosecutors until June 30, 1997, to timely “file” or “refile” a complaint in any child molestation case in which the victim reported the crime to a law enforcement agency between January 1, 1994, and January 1,1997, and in which the complaint either “was not filed within the [one-year] time period specified in [the statute] or was filed within the time period but was dismissed.” (Ibid.) By its own terms, the special savings provision that appeared in former

section 803(g)(3)(B)(ii) as a result of the 1996 amendment applied regardless of when the crime occurred (i.e., “before, on, or after January 1, 1994”), and even where the effect was to “revive” a prosecution that was otherwise time-barred. (Former § 803(g)(3)(B).)

Section 803(

g) currently provides in Ml as Mlows: “

(1) Notwithstanding any other limitation of time described in [section 799 et seq.], a criminal complaint may be filed within one year of the date of a report to a California law enforcement agency by a person of any age alleging that he or she, while under the age of 18 years, was the victim of a crime described in

Section 261, 286, 288, 288a, 288.5, 289, or 289.5. “

(2) This subdivision applies only if both of the following occur: “(
