Definition
A civil officer is any person who holds an appointment under the national government and exercises governmental functions — whether executive or judicial, at any level of federal authority — with the explicit exclusion of officers of the army and navy. The term is principally a constitutional term of art, appearing in Article II, Section 4 of the United States Constitution, which provides that the President, Vice President, and all civil officers of the United States shall be removed from office on impeachment for, and conviction of, treason, bribery, or other high crimes and misdemeanors.
The definition is deliberately broad in scope: grade, department, and the specific nature of duties are not limiting factors. A low-ranking customs official and a federal judge both fall within the category. The decisive question is whether the person holds an appointment under the national government and performs governmental duties in a civil — as opposed to military — capacity.

Common Confusion
Civil officer is frequently confused with the broader category of public officer or government employee. The distinction matters constitutionally: not every person on the federal payroll is a civil officer subject to Senate confirmation under the Appointments Clause or liable to impeachment under Article II. The Supreme Court has drawn a line between officers — who exercise significant authority pursuant to the laws of the United States — and mere employees or agents who perform ministerial or subordinate tasks. A federal contractor or a low-level administrative clerk is not a civil officer in the constitutional sense, even though they work for the federal government.
The term should also be distinguished from civil servant, which is an administrative and statutory category, not a constitutional one, and carries no specific impeachment or appointment consequences.

Core Elements
Three elements define a civil officer within the constitutional framework:
1. Appointment under the national government. The person must derive authority from federal appointment, not from state commission or private contract.
2. Civil capacity. The person must not be an officer of the army or navy. Military officers are excluded from this category by the consistent reading of the constitutional text and all major commentators.
3. Exercise of governmental authority. The person must hold an office — a continuing position with defined duties — rather than merely serve as a temporary agent, employee, or contractor.

Why It Matters in Research
The term does the most significant constitutional work in two contexts: impeachment and the Appointments Clause. Researchers working in either area must track how courts and commentators have defined the outer boundary of the category.
Impeachment research: The scope of who qualifies as a civil officer determines who is subject to congressional impeachment. Historical debates have touched on whether former officers, members of Congress, and territorial officials fall within the term. Territorial organic acts applied the language differently, and researchers examining early Wisconsin territorial materials (as flagged by Rapalje & Lawrence) will find the category treated with some variation in that context.
Appointments Clause research: The constitutional requirement that principal officers be appointed by the President with Senate advice and consent, and that Congress may vest appointment of inferior officers elsewhere, turns on the threshold question of whether someone is an officer at all. Researchers should trace the evolution from the broad 19th-century formulation — essentially anyone appointed under the national government — toward the modern functional test that distinguishes officers from employees based on the exercise of significant authority.
Historical trap: Sources from the 18th and 19th centuries use civil officer expansively, often without the refinement that later Appointments Clause jurisprudence introduced. A researcher reading Rawle or Story for background will encounter a definition that treats any federal appointee as a civil officer, which is broader than the category as modern constitutional doctrine applies it. Do not assume the historical sources map cleanly onto modern distinctions between principal officers, inferior officers, and employees.
Corpus connections: The most productive research path leads from this entry to the Appointments Clause framework. The three-tier distinction among principal officers, inferior officers, and employees — now central to separation of powers litigation — grows directly out of the foundational question of who is a civil officer. The Law Mind Constitutional Law Encyclopedia entry on the Appointment Power elaborates this structure in detail.

Historical Dictionary Support
All three shelf sources — Black's, Bouvier's, and Rapalje & Lawrence — converge on the same core definition: a civil officer is any officer appointed under the national government, whatever the grade or nature of powers, except officers of the army and navy. The unanimity here is striking and reflects that the definition was settled early by reference to the constitutional text and a small cluster of respected commentators, particularly Rawle's Constitution and Story's Commentaries on the Constitution.
Bouvier and Rapalje both cite Rawle's Constitution and Story's Commentaries directly, and these remain the primary interpretive authorities the historical sources rest on. Story's treatment at sections 790–793 of the Commentaries is the most thorough, discussing the scope of the impeachment clause and the logic of excluding military officers from civil officer status.
What the historical dictionaries do not address: the modern Appointments Clause problem of distinguishing officers from employees. That refinement postdates the primary period of these dictionaries' composition. The historical entries assume the category is defined by military/civil contrast and federal/state contrast; they do not engage with whether a federal employee performing ministerial duties qualifies. Researchers should treat the historical definitions as authoritative on the military exclusion and the broad inclusiveness of grade and department, while looking elsewhere for guidance on the officer/employee line.

Jurisdictional Note
Civil officer as a constitutional term applies exclusively to the federal government. States have parallel concepts in their own constitutions — typically defining who is subject to state impeachment and who must be appointed under the state appointments process — but those state definitions operate independently and may diverge significantly from the federal meaning. Researchers working on state impeachment questions should consult state constitutional texts and state-specific commentary rather than extrapolating from the federal definition.
