The decision to participate in the legal process depends in part upon the ideologies of the potential participants. The ideology that has dominated the rights movement during the past two decades is what Stuart Scheingold describes as the myth of rights. But participation in litigation, including rights evolution litigation, has also been colored by other and sometimes conflicting ideologies. Thus the mobilization of legal resources can be seen as the ways participants in litigation cope with multiple ideologies.This paper looks at the mental patient liberation movement in this way. That movement has been very much affected by a myth of rights ideology, as well as by a liberation ideology that is quite contradictory to the tenets of the myth of rights. The paper documents these ideologies, looks at the way the movement has tried to reconcile them, and shows how this problematic reconciliation affects the nature of mental health rights litigation.
