In what circumstances will a plaintiff bring a claim alleging that he was the victim of a conspiracy to deprive him of a constitutional right?

in the right place, and plaintiff is entitled to relief if plaintiff's allegations are true. It must contain a request for particular relief. Plaintiff must identify as a defendant only persons who personally participated in a substantial way in depriving plaintiff of a federal constitutional right. Johnson v. Duffy, 588 F.2d 740, 743 (9th Cir. 1978) (a person subjects another to the deprivation of a constitutional right if he does an act, participates in another's act or omits to perform an act he is legally required to do that causes the alleged deprivation). If plaintiff contends he was the victim of a conspiracy, he must identify the participants and allege their agreement to deprive him of a specific federal constitutional right.
