which house of congress has the power to introduce appropriation bills
Appropriation bill According to the Origination Clause of the United States Constitution, all bills for raising revenue, generally tax bills, must originate in the House of Representatives, similar to the Westminster system requirement that all money bills originate in the lower house. Traditionally, though, appropriation bills also originate in the House of Representatives.[8][9] House appropriations bills begin with "H.R.", meaning "House of Representatives". In reference to revenue bills, the Constitution also states that the "Senate may propose or concur with Amendments as on other Bills." As with revenue bills, the Senate and House each drafts and considers its own appropriation bill. The Senate then "cuts-and-pastes," substituting the language of its version of a particular appropriation bill for the language of the House bill, then agrees to the bill as amended.
United States Congress Article I of the Constitution creates and sets forth the structure and most of the powers of Congress. Sections One through Six describe how Congress is elected and gives each House the power to create its own structure. Section Seven lays out the process for creating laws, and Section Eight enumerates numerous powers. Section Nine is a list of powers Congress does not have, and Section Ten enumerates powers of the state, some of which may only be granted by Congress.[63] Constitutional amendments have granted Congress additional powers. Congress also has implied powers derived from the Constitution's Necessary and Proper Clause.
