Can a majority of the Court of Appeal reverse a district court's decision to dismiss an unarticulated state law claim?

In any event, an unarticulated state law claim could not give the majority a basis for reversing the district court. When the district court, which had original jurisdiction only over the Fourth Amendment claim, dismissed that claim for lack of personal jurisdiction, it was well within its discretion to decline to exercise supplemental jurisdiction over any implicitly lurking state law claim. See 28 U.S.C. 1367(c)(3); Bryant v. Adventist Health Sys./W., 289 F.3d 1162, 1165 (9th Cir.2002) (district court's decision to decline supplemental jurisdiction reviewed for abuse of discretion).
