United States House of Representatives - Wikipedia, the free encyclopedia
Most bills may be introduced in either House of Congress. However, the Constitution provides that
"All bills for raising Revenue shall originate in the House of Representatives." As a result, the Senate does not have the power to initiate bills imposing taxes.
Furthermore, the House of Representatives holds that the Senate does not have the power to originate appropriation bills, or bills authorizing the expenditure of federal funds. Historically, the Senate has disputed the interpretation advocated by the House. However, whenever the Senate originates an appropriations bill, the House simply refuses to consider it, thereby settling the dispute in practice. The constitutional provision barring the Senate from introducing revenue bills is based on the practice of the British Parliament, in which only the House of Commons may originate such measures.
Although it cannot originate revenue bills, the Senate retains the power to amend or reject them. As Woodrow Wilson wrote:
[T]he Senate's right to amend [revenue bills] has been allowed the widest possible scope. The upper house may add to them what it pleases; may go altogether outside of their original provisions and tack to them entirely new features of legislation, altering not only the amounts but even the objects of expenditure, and making out of the materials sent them by the popular chamber measures of an almost totally new character.
The approval of both the Senate and the House of Representatives is required for any bill, including a revenue bill, to become law. Both Houses must pass the exact same version of the bill; if there are differences, they may be resolved by a conference committee, which includes members of both bodies. For the stages through which bills pass in the Senate, see Act of Congress.
