<P> For this purpose, the expression "Public Bill" does not include any Bill for confirming a Provisional Order . </P> <P> Bradley and Ewing said that the statutory definition of Money Bill is "strictly interpreted". Most annual Finance Bills have not been certified to be Money Bills . </P> <P> While the United States of America is not a parliamentary democracy, the Origination Clause of the U.S. Constitution requires that all bills raising revenue originate in the House of Representatives, consistent with British constitutional practice; by convention, appropriation bills (bills that spend money) also originate in the House . Unlike in most Westminster systems, there are no limits on the Senate's ability to amend revenue bills or any requirement for the Senate to approve such bills within a certain timeframe . Both appropriations and revenue bills are often referred to as money bills to contrast them with authorization bills . The U.S. Supreme Court in United States v. Munoz - Flores (1990) held that: "A law passed in violation of the Origination Clause would thus be no more immune from judicial scrutiny because it was passed by both Houses and signed by the President than would be a law passed in violation of the First Amendment". </P>
