Robert MITCHELL, Plaintiff-Appellant, v. c/o GILBERT, Ini McNeil Island Correction Center; et al., Defendants-Appellees, 465 F. App'x 594

MEMORANDUM Robert Mitchell, a Washington state prisoner, appeals pro se from the district court’s

summary judgment in his 42 U.S.C. § 1983 action alleging that defendants violated his constitutional rights. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Jones v. Blanas, 393 F.3d 918, 926 (9th Cir.2004), and we affirm. The district court properly granted

summary judgment on the interference with mail and access to court claims because Mitchell failed to raise a genuine dispute of material fact as to whether defendants interfered with Mitchell’s communications with his attorney, or whether a restriction, other than mail that violated the stop contact order, was placed on his incoming or outgoing mail. See Taylor v. List, 880 F.2d 1040, 1045 (9th Cir.1989) (party opposing

summary judgment may not rest on conclusory allegations or mere assertions). The district court properly granted

summary judgment on Mitchell’s claim for restoration of and/or proper calculation of good time credit because resolution of the claim would necessarily implicate the length of Mitchell’s confinement. See Edwards v. Balisok, 520 U.S. 641, 645, 117 S.Ct. 1584, 137 L.Ed.2d 906 (1997) (challenge to loss of good-time credits not cognizable under § 1983); Heck v. Humphrey, 512 U.S. 477, 486-87, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994) (§ 1983 claims that necessarily challenge the fact or duration of confinement are barred).

Mitchell’s contention that the district court should have granted him a continuance so that he could conduct additional discovery fails because Mitchell did not move the court for additional discovery as required by Federal Rule of Civil Procedure 56(d). See Barona Grp. of the Capitan Grande Band of Mission Indians v. Am. Mgmt. & Amusement, Inc., 840 F.2d 1394, 1400 (9th Cir.1987) (reference to a need for discovery in memoranda and declarations insufficient to satisfy requirements for Rule 56 motion for additional discovery). We decline to consider Mitchell’s challenge to the lawfulness of the stop contact order.

See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir.1999) (court of appeals will not consider issues not properly raised before the district court). Mitchell’s remaining contentions are unpersuasive. AFFIRMED. This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3.
