Definition
The execution of power refers to the lawful exercise or carrying into effect of an authority that has been granted by law, instrument, or office. The term operates across several distinct legal contexts, each with its own doctrinal content.
1. In the law of powers (property and trusts): The act by which a donee of a power performs the steps necessary to give legal effect to that power. A power of appointment, for example, is not self-executing — it requires some affirmative act by the donee, typically in the form required by the instrument creating the power (e.g., a will, deed, or written instrument), to appoint the property. The execution is the donee's formal exercise of the authority conferred. An attempted execution that fails to meet formal requirements may be void, wholly ineffective, or subject to equitable correction depending on jurisdiction and doctrine.
2. In constitutional and public law: The carrying out of governmental authority vested in an executive branch, officer, or agency. Article II of the U.S. Constitution vests executive power in the President, who is charged with taking care that laws be faithfully executed. The "execution" of this power encompasses enforcement of statutes, direction of administrative agencies, conduct of foreign relations, and deployment of law enforcement authority. The limits on how executive power may be exercised — and who may execute it — lie at the heart of separation-of-powers doctrine.
3. In historical usage: Courts of equity and early English courts recognized the "execution of statutes" as a specific function — meaning the enforcement or giving effect to parliamentary acts by judicial or prerogative authority. The Court of Star Chamber was historically described as existing for, among other purposes, the execution of statutes.

Common Confusion
Researchers should distinguish execution of power from execution as a remedy (the enforcement of a court judgment through writ of execution) and from execution of an instrument (signing and delivering a deed or contract). All three senses of "execution" appear in proximity in legal sources, and historical dictionaries often treat them under a single heading. In the law of powers specifically, "execution of a power" is sometimes confused with "exercise of a power" — the terms are often used interchangeably, but strict usage reserves "execution" for the formal act and "exercise" for the broader decision to deploy the power at all.

Core Elements
For execution of a power in the property/trust context, courts have traditionally examined:
Capacity: Whether the donee is legally capable of executing the power at the relevant time.
Mode and Form: Whether the instrument or act used to execute the power conforms to the requirements specified in the creating instrument (e.g., must be by will, must be by deed, must refer explicitly to the power).
Scope: Whether the appointment falls within the objects and range authorized by the power — an appointment beyond the scope of the power is void as a fraud on the power.
Completeness: Whether the donee has done everything required to make the execution operative, or whether steps remain that could cause the execution to fail or lapse.

Why It Matters in Research
Researchers face two largely separate bodies of doctrine depending on which sense of the term they are pursuing.
For property and trusts research, the execution of a power is a technical act with significant formal requirements that vary by the type of power (general, special, or hybrid), the governing instrument, and the jurisdiction. Historical sources — including equity treatises through the nineteenth century — contain extensive doctrine on defective execution, illusory appointments, and equitable correction. The modern Restatement (Third) of Property: Wills and Other Donative Transfers consolidates much of this, but researchers using older case law or secondary sources should be alert to doctrinal evolution. The distinction between a power well executed, a defectively executed power that equity might save, and a void attempt is not always drawn consistently across sources.
For constitutional and administrative law research, "execution of power" as a phrase appears less often as a term of art than as a descriptive phrase. The operative doctrinal vocabulary shifts to "executive power," "executive authority," "delegation," and "faithful execution." Researchers pursuing questions about limits on executive action, the removal power, or agency authority should use those more specific terms to locate relevant encyclopedia and case material rather than the phrase "execution of power" alone.
In historical sources, watch for the conflation of execution-of-power doctrine with execution-of-statutes doctrine. The Star Chamber reference in Rapalje & Lawrence illustrates how "execution" in early English legal writing could mean judicial enforcement of parliamentary commands — a usage with no close modern analog but which appears in early treatises discussing prerogative courts.

Historical Dictionary Support
Rapalje & Lawrence's entry is fragmentary on this term. The editors gesture toward "execution of statutes" as a recognized historical category tied to the Court of Star Chamber under the statute 3 Hen. VII, c. 1, and refer readers elsewhere for substantive treatment. The entry for "execution, quasi" — citing 3 Ves. & B. 105, 107 — suggests that equity courts recognized intermediate or analogous forms of execution, though the context (likely trusts or powers) is not spelled out in the surviving excerpt.
What historical dictionaries largely omit is a systematic account of the formal requirements for executing a private power — that treatment lived primarily in equity treatises (Sugden on Powers being the foundational English text) rather than in legal dictionaries. Researchers relying solely on dictionary sources for this doctrine will find them pointing outward to case reporters and treatises rather than synthesizing the substantive rules.

Jurisdictional Note
In the property context, the formal requirements for executing a power are governed by state law in the United States, and they vary. Some states have modernized their rules to reduce hypertechnical failures of execution; others retain older requirements. Where a power must be executed by will, the Wills Act formalities of the relevant jurisdiction apply. Researchers should not assume that equitable doctrines saving defective executions recognized in one jurisdiction will be available in another.
