PER CURIAM. Robert Philpott appeals the district court’s adverse grant of
summary judgment in his 42 U.S.C. § 1983 action, in which he claimed violations of his Fourth Amendment rights based on his warrant-less arrest and the search and seizure of his vehicle, and claimed defamation and other state-law violations. Upon careful de novo review, see Veatch v. Bartels Lutheran Home, 627 F.3d 1254, 1257 (8th Cir.2010), we conclude that the district court properly granted
summary judgment on Philpott’s Fourth Amendment claims, see Brodnicki v. City of Omaha, 75 F.3d 1261, 1264-66 (8th Cir.1996) (discussing probable-cause standard for warrantless arrest); see also United States v. Kimhong Thi Le, 474 F.3d 511, 514-15 (8th Cir.2007) (discussing constitutional standards for im-poundment of vehicle, and inventory search of vehicle, without warrant). Furthermore, we agree that Philpott’s defamation claim failed as a matter of law to state a claim under
section 1983, see Paul v. Davis, 424 U.S. 693, 710-12, 96 S.Ct. 1155, 47 L.Ed.2d 405 (1976) (injury to reputation alone cannot support claim for deprivation of liberty interest without accompanying alteration of legal status or right), and we conclude that the district court did not abuse its discretion in declining to exercise supplemental jurisdiction over Philpott’s state-law claims, see 28 U.S.C. § 1367(c)(3) (court may decline to exercise supplemental jurisdiction over claim if it has dismissed all claims over which it had original jurisdiction); Gibson v.
Weber, 433 F.3d 642, 647 (8th Cir.2006) (standard of review). Accordingly, we affirm. See 8th Cir. R. 47B. . The Honorable Robert T. Dawson, United States District Judge for the Western District of Arkansas, adopting the report and recommendations of the Honorable James R. Mar-schewski, United States Magistrate Judge for the Western District of Arkansas.
