Sinclair v. United States

Background

Harry F. Sinclair, president of the Mammoth Oil Company, was called to testify before the Senate Committee on Public Lands and Surveys about leases and contracts involving naval oil reserves. The Government had made leases and contracts for portions of those reserves and the Senate adopted resolutions to investigate possible fraud and to protect the public interest. Sinclair appeared several times, produced papers, and on one later appearance gave a statement saying he would reserve further testimony for the courts and would not answer certain questions. He was later indicted for willfully refusing to answer a committee question about a contract tied to the Teapot Dome area.

Reasoning

The Court examined whether the Senate committee had authority to investigate and whether the committee’s question was properly related to that inquiry. The Court held the committee was authorized to investigate public land leases affecting the United States as owner and that the question about the contract was relevant to that investigation. The Court also ruled that whether a question is pertinent is for the judge to decide as a matter of law, not for the jury, and that a witness’s good-faith reliance on counsel about the law does not excuse a deliberate refusal to answer when the question is legally pertinent.

Real world impact

The ruling affirms that Congress may require answers about government land deals and that witnesses can be criminally punished for refusing pertinent questions. It makes clear judges, not juries, decide whether committee questions are tied to a legitimate inquiry, and that claiming mistaken legal advice is not a defense to deliberate refusal to testify.
