Whether inadequate medical care for a prisoner can constitute cruel and unusual punishment under the Eighth Amendment.
Holding
Yes. Deliberate indifference to a prisoner's serious medical needs constitutes cruel and unusual punishment and is actionable under § 1983.
Reasoning
The Eighth Amendment reaches more than historically barbaric punishments. It reflects contemporary standards of dignity, humanity, and decency, and it prohibits the unnecessary and wanton infliction of pain. Those principles apply to the conditions under which the State carries out incarceration.
Because prisoners cannot independently obtain medical care, the government has an affirmative obligation to address their serious medical needs. A failure to provide necessary care can cause needless pain, suffering, permanent injury, or death without any legitimate penological purpose.
Deliberate indifference may be shown by prison doctors' response to serious medical needs, by guards' intentional denial or delay of access to medical care, or by intentional interference with prescribed treatment. The constitutional concern is the knowing disregard of a serious illness or injury, not simply imperfect medical outcomes.
