What is the test for finding a supervisor to be liable for deprivation of a plaintiff's constitutional rights?

his or her personal involvement in the constitutional deprivation, or (2) a sufficient causal connection between the supervisor's wrongful conduct and the constitutional violation.'" Starr v. Baca, 652 F.3d 1202, 1207 (9th Cir. 2011) (quoting Hansen v. Black, 885 F.2d 642, 646 (9th Cir.1989)). In this case, it does not appear from the allegations of plaintiff's amended complaint that the supervisory defendants were personally involved in the alleged deprivation of his constitutional rights. If plaintiff wishes to proceed against any supervisory defendants, he will need to allege facts in his second amended complaint clarifying the causal connection between the defendants and his alleged constitutional deprivations.
