Good law. Still followed. Later cases may have narrowed it — see Scope. Binds every court in the country on the federal question it decides.

What happened

Kansas required an incarcerated man to join a sex offender treatment program in which participants had to disclose their offense history, including uncharged conduct, with no immunity. Refusing meant losing privileges and being moved to a more restrictive unit.

What the court decided

The Court held that these consequences did not amount to unconstitutional compulsion under the Fifth Amendment’s privilege against self-incrimination. The judgment rests on a four-justice plurality and a concurrence by Justice O’Connor, who agreed on the result under a narrower test.

Why it matters to the Registry

This is why treatment programs — in prison, and often as a condition of probation or parole — can require disclosure of past conduct. The fight in later cases is over where the penalty for refusing becomes coercive: added prison time or revoked supervision can be treated differently from lost privileges.

What it did not decide

It did not approve harsher penalties for refusing, such as a longer prison term or revoked parole or supervised release; Justice O’Connor, whose narrower concurrence controls, suggested added prison time would be compulsion.
