Superintendent, Mass. Correctional Institution at Walpole v. Hill

Background

Two Massachusetts inmates were disciplined after a guard found a beaten inmate and saw three other inmates, including the two respondents, running away. A prison board found them guilty of involvement, took away 100 days of “good time” credit and ordered isolation. The Massachusetts trial court and state supreme court ruled the record contained no evidence sufficient under the Constitution to support the board’s finding, and the state restored the lost credits.

Reasoning

The Supreme Court addressed whether the Constitution allows revocation of good-time credits when the board’s decision is not supported by any evidence. Assuming that good-time credits are a protected liberty interest, the Court held that due process requires “some evidence” in the record to support a revocation. That standard means a court need only ask whether any evidence exists that could support the board’s conclusion; courts should not reweigh credibility or examine the whole record. Applying that rule, the Court found the guard’s testimony and written report met the “some evidence” standard and reversed the state court’s judgment.

Real world impact

The ruling requires prison disciplinary boards to record and rely on at least some factual basis before taking away good-time credits. Courts reviewing such punishments will look only for minimal evidentiary support, not reassess witness credibility or substitute their judgment. In this case, the disciplinary decision was reinstated because the record contained enough evidence under the constitutional standard.

Dissents or concurrances

Justice Stevens (joined by Justices Brennan and Marshall) agreed with Parts I–III but dissented from the Court’s reversal of the state judgment, criticizing the Court’s de novo review and the State’s handling of state-law review issues.
