County of Riverside v. McLaughlin

Riverside County's (defendant's) policy combined probable-cause determinations with arraignments within 48 hours of a warrantless arrest, excluding weekends and holidays, meaning some arrestees could wait well over 48 hours; McLaughlin and a certified class of detainees (plaintiffs) obtained a preliminary injunction from the district court requiring determinations within 36 hours, which the Ninth Circuit affirmed as necessary to satisfy Gerstein v. Pugh's requirement of a "prompt" probable-cause determination.
