Appropriation is the constitutional mechanism by which a legislature grants the executive legal authority to draw money from the public treasury and spend it on stated objects. It rests on the foundational principle that no money may leave the consolidated fund of a state without prior legislative sanction. In the United States this is anchored in the Appropriations Clause, Article I, Section 9, Clause 7 of the Constitution: "No Money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law." In the Indian system the parallel rule is Article 114, which requires an Appropriation Act before any sum is withdrawn from the Consolidated Fund of India, and Article 266, which establishes that fund. The doctrine traces to the 1689 English Bill of Rights and the older principle that the Crown could not levy or spend without Parliament — the historical root of the legislature's "power of the purse."
Operationally, appropriation distinguishes the authority to spend from the act of taxation (which raises revenue) and from authorization legislation (which creates a program or agency). A program may be authorized in law yet receive no money until an appropriation is enacted; conversely funds appropriated must be spent only on the purpose specified and within the fiscal year or period stated, after which they typically lapse. In the U.S. federal process, after the President submits a budget, the House and Senate Appropriations Committees draft twelve regular appropriations bills covering discretionary spending; mandatory spending (entitlements like Social Security) flows from permanent appropriations and is not subject to the annual cycle. The Antideficiency Act prohibits officials from obligating funds in excess of or in advance of appropriations, and its violation is the legal basis for a government shutdown when appropriations lapse. In India, the Comptroller and Auditor-General audits whether expenditure conformed to the appropriation, reporting excesses to the Public Accounts Committee.
Named instances illustrate the stakes. The U.S. government shutdowns of 2013 (16 days) and December 2018–January 2019 (35 days, the longest in history) occurred because Congress failed to pass appropriations or a continuing resolution, triggering the Antideficiency Act. The Impoundment Control Act of 1974 limits a President's ability to refuse to spend appropriated funds, a power President Nixon had asserted; this statute returned in 2025 debate over executive impoundment claims. India's "guillotine" procedure, the Vote on Account under Article 116, and the demands for grants debated each March remain live mechanisms in 2026 budget sessions.
For the FSOT Job Knowledge component, appropriation is tested as part of U.S. government structure, the budget and federal funding process, and the separation-of-powers checks Congress exercises over the executive. Expect questions distinguishing appropriations from authorizations, identifying the Appropriations Clause, explaining continuing resolutions and shutdowns, and naming the Antideficiency Act. UPSC and CSS aspirants encounter the cognate concept through Articles 112–117 (the Annual Financial Statement, demands for grants, and Appropriation Bills) and the CAG's audit role under Article 148.
Example
In December 2018, the U.S. federal government entered a 35-day shutdown — the longest in history — when Congress and President Trump failed to enact appropriations for several departments, leaving them without legal authority to spend.
Frequently asked questions
