Civil Contempt in the Senate.

As an alternative to both the inherent contempt power of each House and the criminal contempt statutes, in 1978 Congress enacted a civil contempt procedure, which is applicable only to the Senate. The statute gives the U.S. District Court for the District of Columbia jurisdiction over a civil action to enforce, secure a declaratory judgment concerning the validity of, or to prevent a threatened failure or refusal to comply with, any subpoena or order issued by the Senate or a committee or subcommittee. Generally such a suit will be brought by the Senate Legal Counsel, on behalf of the Senate or a Senate committee or subcommittee.

Civil contempt, however, has limitations. Most notable is that the statute granting jurisdiction to the courts to hear such cases is, by its terms, inapplicable in the case of a subpoena issued to an officer or employee of the federal government acting in their official capacity.

During the course of the debates regarding this legislation, the executive branch strongly opposed conferring jurisdiction upon the federal courts to decide such sensitive issues between Congress and the executive branch. Testifying before a subcommittee of the Senate Committee on Governmental Operations, then-Assistant Attorney General Antonin Scalia argued that weighing the legislature’s need for information against the executive’s need for confidentiality is “the very type of ‘political question’ from which ... the courts [should] abstain.” In response, Congress amended the proposed legislation excluding from its scope federal officers and employees acting in their official capacity. However, as noted in a report from the House Judiciary Committee in 1988, the exclusion was to apply only in cases in which the President had directed the recipient of the subpoena not to comply with its terms.
