Definition
To authorize is to grant legal power, permission, or authority to a person or entity to perform a specified act. Authorization is both the act of conferring that power and the resulting condition of being empowered. In legal usage, the term carries two closely related but distinct functions:
1. Conferring authority on an agent or official. To authorize another is to invest them with the legal capacity to act on behalf of the authorizing party or institution — binding that party by the acts performed within the scope of the authorization. This is the core meaning in agency, corporate, and administrative law.
2. Giving legal sanction to an act. To authorize a transaction, instrument, or course of conduct is to render it lawful — removing any legal defect that would otherwise exist. A legislature authorizes expenditures; a court authorizes a settlement; a principal authorizes a contract.
Authorization is distinct from mere permission in degree: authorization typically carries legal effect and accountability, while permission may be informal or revocable without consequence.
Common Language
Modern common usage (Wiktionary): To grant someone the permission or power necessary to do something; to permit, sanction, or consent to.
Historical common usage (Webster's 1913): To clothe with authority, warrant, or legal power; to give a right to act; to empower. Also, to make legal; to give legal sanction to; to legalize.
The common and legal meanings are closely aligned, but the legal sense imposes a structural consequence the everyday sense does not: legal authorization creates enforceable rights, duties, and liabilities. When a manager casually "authorizes" an employee to make a purchase, ordinary usage is satisfied. When a corporate officer authorizes the same purchase, agency law may bind the corporation to third parties and expose it to liability — regardless of the officer's internal intent. The stakes embedded in the legal meaning are invisible in the common one.
Common Confusion
AUTHORIZE vs. RATIFY: Authorization precedes the act — authority is granted before the agent acts. Ratification follows an unauthorized act and retroactively supplies the authority that was missing. A researcher encountering either term in historical documents about agency relationships should confirm which temporal sequence the source describes.
AUTHORIZE vs. EMPOWER: Often used interchangeably, but "empower" more commonly appears in constitutional and statutory grants of legislative or administrative power ("Congress is empowered to..."), while "authorize" more commonly appears in transactional and agency contexts. In regulatory sources, the distinction in drafting convention can signal the source and scope of the power being described.
Why It Matters in Research
Authorization is a load-bearing term across nearly every legal domain, and its meaning shifts depending on context. Researchers should keep three research traps in mind.
First, scope questions dominate historical disputes. Whether an act was within the scope of authorization — not merely whether authorization existed — is the recurring litigation issue in agency, corporate, and governmental contexts. Historical case law often turns on implied versus express authorization, and older sources may use the terms loosely or interchangeably. Anderson's citation to Atwill v. Ferrett (1846) and Kent's Commentaries reflects the 19th-century preoccupation with defining the outer edges of delegated authority.
Second, constitutional authorization operates on a different register. When authorization appears in constitutional materials — particularly in separation-of-powers disputes, war powers contexts, or delegation doctrine — it signals structural legal questions about which branch or level of government possesses the power to act at all. The encyclopedia entry on Commander-in-Chief Power is directly relevant here: presidential military action often turns on whether Congress has authorized it, whether that authorization is express or implied, and whether the absence of authorization is itself legally significant.
Third, statutory authorization in administrative law connects to the nondelegation doctrine and Chevron-era deference questions. Whether an agency was "authorized" to act by its enabling statute is the first-order question in administrative review. Researchers working with post-2020 administrative law materials should be alert to the major questions doctrine, which requires clear congressional authorization for rules of significant economic or political consequence — a standard that sharpens what "authorized" must mean in statutory text.
Historical Dictionary Support
Anderson's definition — "to confer power upon; to invest with lawful authority" — captures the transactional core of the term as it functioned in 19th-century agency and property law. The citation to Atwill v. Ferrett and Kent's Commentaries reflects the period's concern with distinguishing valid delegations of authority from acts performed in excess of them. Webster's 1913 adds the sanctioning function explicitly ("to make legal; to give legal sanction to"), which Anderson gestures at but does not separately enumerate.
Neither historical source engages with the constitutional or administrative dimensions of authorization — understandably, given the administrative state's limited development at the time. Researchers using Anderson or Kent-era sources to understand modern statutory authorization questions should treat those sources as background on the private-law structure of the concept, not as guides to its public-law applications.
Jurisdictional Note
Authorization doctrine is generally consistent in structure across U.S. jurisdictions, but the formalities required — particularly in corporate and real property contexts — vary by state statute. Some states require board resolutions or written authorization for specific transactions; others permit implied authorization more readily. Researchers working on historical real estate or corporate records should verify the applicable state's requirements for the relevant period.
