What is the test for a federal court to hear a pro se pleading in a civil case brought by a prisoner seeking damages from a governmental entity or officer or employee?

Federal courts must engage in a preliminary screening of cases in which prisoners seek redress from a governmental entity or officer or employee of a governmental entity. 28 U.S.C. 1915A(a). In its review, the court must identify any cognizable claims, and dismiss any claims that are frivolous, malicious, fail to state a claim upon which relief may be granted, or seek monetary relief from a defendant who is immune from such relief. Id. at 1915A(b)(1),(2). Pro se pleadings must be liberally construed. Balistreri v. Pacifica Police Dep't, 901 F.2d 696, 699 (9th Cir. 1990).
