Whether the Fourteenth Amendment permits a witness to be secretly tried, convicted, and jailed for contempt during a one-man grand-jury investigation.
Holding
No. A person may not be sentenced to imprisonment after a wholly secret contempt trial; such secrecy violates the Due Process Clause of the Fourteenth Amendment.
Reasoning
The Court distinguished a grand jury’s investigative role from a court’s punitive role. Grand juries may generally conduct investigations in secret, but they do not try defendants, enter judgments, or impose prison sentences. Once the judge-grand juror charged Oliver with contempt and sentenced him to jail, Oliver was no longer merely a witness in a confidential investigation; he was an accused person entitled to the procedural protections governing criminal punishment.
Public criminal proceedings are a deeply rooted Anglo-American safeguard against arbitrary government action. Public access helps ensure that judges exercise their authority fairly, permits public scrutiny of the administration of justice, and protects accused persons from persecution. Although courts have differed over limited exclusions from trials, the Court found no American practice allowing an accused to be tried, convicted, and imprisoned while everyone, including counsel, relatives, and friends, is excluded.
Michigan’s procedure was especially troubling because secrecy continued at every stage. Oliver was accused, convicted, and removed to jail without any public proceeding, and his lawyer was allegedly denied access to him even after incarceration. The state supreme court then upheld the commitment without reviewing a complete record. In light of the historic prohibition on secret criminal trials, this process fell below the minimum demanded by due process.
