Practically every power of the National Government has been expanded in some degree by the coefficient clause. Under its authority Congress has adopted measures requisite to discharge the treaty obligations of the nation;[1395] it has organized the federal judicial system and has enacted a large body of law defining and punishing crimes. Effective control of the national economy has been made possible by the authority to regulate the internal commerce of a State to the extent necessary to protect and promote interstate commerce.[1396] Likewise the right of Congress to utilize all known and appropriate means for collecting the revenue, including the distraint of property for Federal taxes,[1397] and its power to acquire property needed for the operation of the government by the exercise of the power of eminent domain,[1398] have greatly extended the range of national power. But the widest application of the necessary and proper clause has occurred in the field of monetary and fiscal controls. Inasmuch as the various specific powers granted by article I, section 8, do not add up to a general legislative power over such matters, the Court has relied heavily upon this clause in sustaining the comprehensive control which Congress has asserted over this subject.[1399] DEFINITION AND PUNISHMENT OF CRIMES Although the only crimes which Congress is expressly authorized to punish are piracies, felonies on the high seas, offenses against the law of nations, treason and counterfeiting of the securities and current coin of the United States, its power to create, define and punish crimes and offenses whenever necessary to effectuate the objects of the Federal Government is universally conceded.[1400] Illustrative of the offenses which have been punished under this power are the alteration of registered bonds;[1401] the bringing of counterfeit bonds into the country;[1402] conspiracy to injure prisoners in custody of a United States marshal;[1403] impersonation of a federal officer with intent to defraud;[1404] conspiracy to injure a citizen in the free exercise or enjoyment of any right or privilege secured by the Constitution or laws of the United States;[1405] the receipt by government officials of contributions from government employees for political purposes;[1406] advocating, etc., the overthrow of the Government by force.[1407] Part I of Title 18 of the United States Code comprises more than 500 sections defining penal offenses against the United States.
