Actual conditions of prisoner's solitary confinement present a genuine issue of material fact for trial.
State statute imposing conditions for the incarceration of prisoners whose death sentences have been commuted, passed after the legislative elimination of the death penalty and prior to the judicial determination that those already sentenced to death should have their sentences commuted, was an unconstitutional Bill of Attainder, imposing specific punishments on implicitly designated specific persons without the benefit of trial.
Classification of prisoner as a higher security threat than others similarly situated had no rational basis, and violated Equal Protection.

Eighth Amendment claims of mistreatment of prisoners require an element of subjective intent.
