Appropriation Bill(redirected from Supply Bill)
Also found in: Dictionary, Thesaurus, Wikipedia.
Legislation that authorizes the government to spend money from the public treasury for a certain purpose. For example, an appropriation bill may enable the defense ministry to fund the military's activities for the year. If the amount authorized in all appropriation bills in a year exceeds the revenue the government collects, then the government goes into deficit. In many countries, appropriation bills must originate in the lower house of the legislature.
