If Congress so provides, violations of valid administrative regulations may be punished as crimes.[79] But the penalties must be provided in the statute itself; additional punishment cannot be imposed by administrative action.[80] In an early case, the Court held that a section prescribing penalties for any violation of a statute did not warrant a prosecution for wilful disobedience of regulations authorized by, and lawfully issued pursuant to, the act.[81] Without disavowing this general proposition, the Court, in 1944, upheld a suspension order issued by the OPA whereby a dealer in fuel oil who had violated rationing regulations was forbidden to receive or deal on that commodity.[82] Although such an order was not explicitly authorized by statute, it was sustained as being a reasonable measure for effecting a fair allocation of fuel oil, rather than as a means of punishment for an offender. In another OPA case, the Court ruled that in a criminal prosecution, a price regulation was subject to the same rule of strict construction as a statute, and that omissions from, or indefiniteness in, such a regulation, could not be cured by the Administrator's interpretation thereof.[83] Congressional Investigations INVESTIGATIONS IN AID OF LEGISLATION No provision of the Constitution expressly authorized either house of Congress to make investigations and exact testimony to the end that it may exercise its legislative function effectively and advisedly. But such a power had been frequently exercised by the British Parliament and by the Assemblies of the American Colonies prior to the adoption of the Constitution.[84] It was asserted by the House of Representatives as early as 1792 when it appointed a committee to investigate the disaster to General St. Clair and his army in the Northwest and empowered it to "call for such persons, papers, and records, as may be necessary to assist their inquiries."[85] CONDUCT OF EXECUTIVE DEPARTMENT
