Summary
Background
M. S. Daugherty, a bank president and brother of Attorney General Harry M. Daugherty, was subpoenaed by a Senate committee investigating the Justice Department. He failed to obey two subpoenas, and the Senate ordered a warrant directing the Sergeant at Arms to bring him before the Senate. The Sergeant at Arms authorized his deputy, John J. McGrain, who arrested Daugherty in Cincinnati. Daugherty sought habeas relief in federal district court and was discharged, prompting the Government’s direct appeal to this Court.
Reasoning
The Court addressed whether either house of Congress may, as part of its lawmaking role, compel private witnesses to appear and testify. Reviewing long-standing legislative practice, statutes (including acts of 1798 and 1857), and precedent, the Court held that the power to inquire and use process to enforce testimony is an appropriate and necessary auxiliary to the power to legislate. It also found (1) the Senate’s standing rule authorized deputies and the deputy’s execution of the warrant was valid, (2) a committee report made under senators’ oaths satisfied the Fourth Amendment’s support requirement for the warrant, and (3) the investigation’s subject — the administration of the Department of Justice — was properly within the Senate’s legislative concern. The Court concluded the district court erred in discharging the witness.
Real world impact
The decision confirms that Congress can enforce subpoenas and use attachments to obtain testimony for legislative investigations, including from private bank officers and other witnesses. It also recognizes judicial oversight where a committee exceeds its proper bounds. The Court held the case was not moot and reversed the discharge so the investigation could proceed.
