Can a prison official be held liable for deliberate indifference in a common law negligence claim?

To act with deliberate indifference, a prison official must both be aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference. Farmer v. Brennan, 511 U.S. 825, 837 (1994). Thus, a defendant is liable if he knows that plaintiff faces "a substantial risk of serious harm and disregards that risk by failing to take reasonable measures to abate it." Id. at 847.

It is important to differentiate common law negligence claims of malpractice from claims predicated on violations of the Eighth Amendment's prohibition of cruel and unusual punishment. In asserting the latter, "[m]ere 'indifference,' 'negligence,' or 'medical malpractice' will not support this cause of action." Broughton v. Cutter Laboratories, 622 F.2d 458, 460 (9th Cir. 1980) (citing Estelle, 429 U.S. at 105-06; see also Toguchi v. Chung, 391 F.3d 1051, 1057 (9th Cir. 2004).
