Does plaintiff's claim under Section 1983 confer federal subject matter jurisdiction?

Nor do plaintiff's state law claims confer federal subject matter jurisdiction. See Galen v. County of Los Angeles, 477 F.3d 652, 662 (9th Cir. 2007) ("Section 1983 requires [plaintiff ] to demonstrate a violation of federal law, not state law."). In the absence of a cognizable federal claim, and because violations of state law are not cognizable under Section 1983, this court cannot exercise supplement jurisdiction over plaintiff's putative state law claims.² Cf. Ove v. Gwinn, 264 F.3d 817, 826 (9th Cir. 2001) (district court has discretion to decline to exercise supplemental jurisdiction over state law claims upon dismissal of all claims over which it has original jurisdiction).
