An inmate’s right to challenge what he calls deplorable conditions of confinement at the federal prison at Ray Brook, N.Y., has been restored by the U.S. Court of Appeals for the Second Circuit.

The circuit said that Ellis Walker, who claims he was jammed into a 174-square-foot cell with five other inmates for almost 28 months, can pursue a claim of cruel and unusual punishment under the U.S. Constitution’s Eighth Amendment.
