From the Ninth Circuit today in Serra v. Lappin:

Current and former federal prisoners allege that the low wages they were paid for work performed in prison violated their rights under the Fifth Amendment and various sources of international law. Plaintiffs sued officials of the Bureau of Prisons for damages and injunctive and declaratory relief. We conclude that prisoners have no enforceable right to be paid for their work under the Constitution or international law, and we affirm the district court's dismissal of the action.

Perpetual pain in the rear J. Tony Serra et al. had the misfortune to draw a USCA9 panel with an unusually high sense quotient for that court: Kozinski, Wallace, and Clifton. So look for a petition for rehearing en banc.
