Homeless plaintiffs and advocates have successfully challenged laws or practices that punish homeless people for sleeping or conducting other life-sustaining activities in public. In a recent case from the Ninth Circuit, homeless plaintiffs successfully challenged the enforcement of a Los Angeles ordinance that makes it a crime to sit, sleep, or lie down in public spaces throughout the entire city (Jones v. City of Los Angeles, 444 F.3d 1118 (9th Cir. 2006)(vacated by Jones v. City of Los Angeles, 505 F.3d 1006 (9th Cir. 2007))).
