Starr v. County of Los Angeles, 659 F.3d 850

Starr, an inmate in Los Angeles County Jail, sues Sheriff Baca in his individual capacity under 42 U.S.C. §1983 for unconstitutional conditions of confinement based on deliberate indifference.
On January 27, 2006, Starr was attacked by inmates after a deputy opened his cell; Starr was stabbed multiple times and beaten, with a racially charged taunt and further injury when deputies failed to protect him.
The district court dismissed Starr's supervisory liability claim as to Baca under Rule 12(b)(6) for lack of causal connection; Starr appeals.
The Ninth Circuit reviews de novo a Rule 12(b)(6) dismissal; the court addresses Iqbal’s impact on supervisory liability and analyzes whether Starr’s complaint satisfies Rule 8(a).
The court reverses the district court, holds supervisory liability for deliberate indifference remains viable post-Iqbal, and remands for further proceedings.
Dissent by Judge Trott argues Starr failed to plead personal involvement and causal link; would affirm dismissal in part.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Iqbal's effect on supervisory liability	Iqbal does not bar supervisor liability for deliberate indifference.	Iqbal eliminates supervisory liability claims.	Iqbal does not alter supervisory liability in confinement cases.
Adequacy of Rule 8(a) pleading post-Iqbal	Complaint contains detailed, non-conclusory facts showing deliberate indifference by Baca.	Complaint relies on mere conclusory assertions.	Complaint sufficiently pleads supervisory liability under Rule 8(a).
Causation and knowledge as basis for liability	Baca knew of subordinates' unconstitutional conduct and acquiesced.	Knowledge alone is insufficient without personal involvement or explicit policy.	Sufficient causal connection and acquiescence shown to state a claim.
