Parliament gives statutory authority for the government to draw funds from the Consolidated Fund by Acts of Parliament known as Appropriation Acts and Consolidated Fund Acts. Funds are made available under the Acts only for a specified financial year, a concept known as "annuality", although an individual Act can cover more than one financial year, listing separate amounts for each. Often a two-year period is covered by a Consolidated Fund Act, and roughly two or three are passed in each parliamentary year.
