Definition
Resisting an officer is a criminal offense consisting of obstructing, opposing, or endeavoring to prevent a peace officer from performing a lawful duty — including making an arrest, executing legal process, or otherwise enforcing the peace. The offense may be committed with or without actual physical force; interference by words, flight, or passive non-compliance can satisfy the conduct element in many jurisdictions, depending on how the statute is written.
The offense is closely associated with, but distinct from, resisting arrest specifically. Resisting an officer is the broader category: it covers interference with an officer acting in any official capacity, not merely during an arrest. A person who physically blocks an officer from serving a writ, for example, may be guilty of resisting an officer even though no arrest was being attempted.
Two elements are universally required: (1) the officer must have been acting in the lawful discharge of duty at the time of the resistance, and (2) the defendant must have known, or reasonably should have known, that the person being resisted was a peace officer. An unlawful arrest or an officer acting outside the scope of authority traditionally negated the offense at common law — though this common law rule has been substantially modified by statute in many states.

Common Language
Modern common usage (Wiktionary): "Resisting an officer" or "resisting arrest" is understood in ordinary speech as physically struggling against or fleeing from police.
Historical common usage (Webster's 1913): "Resist" — to strive against; to exert force in opposition; to counteract or withstand.
The gap matters here. Ordinary usage implies physical struggle. Legally, the offense is far broader: verbal interference, passive non-compliance, and in some jurisdictions merely providing false identification, can constitute resisting an officer. Researchers working with historical sources should be cautious — the physical/non-physical boundary has shifted considerably across time and jurisdiction, and early cases often required actual force where modern statutes do not.

Common Confusion
RESISTING AN OFFICER vs. RESISTING ARREST: Resisting arrest is a narrower offense limited to interference during an arrest. Resisting an officer covers interference with any lawful exercise of official duty — service of process, execution of a warrant, crowd control, and similar functions. Many modern statutes have collapsed the distinction, using "obstruction" or "interference" language broad enough to cover both. Historical sources frequently use the two terms interchangeably, which can mislead.
RESISTING AN OFFICER vs. ASSAULT ON AN OFFICER: These are separate offenses, though conduct may satisfy both. Assault on an officer involves an intentional harmful or offensive contact (or apprehension thereof) directed at the officer. Resisting an officer focuses on the act of opposition to the official function, not the physical contact itself. A defendant may be charged with both arising from the same incident.
RESISTING AN OFFICER vs. OBSTRUCTION OF JUSTICE: Obstruction of justice is a broader and often federally charged offense covering interference with judicial or investigative proceedings. Resisting an officer is a street-level, real-time offense; obstruction reaches further into tampering with evidence, witnesses, and process. They share conceptual overlap but occupy different doctrinal spaces.

Core Elements
The elements most courts and statutes require:
1. LAWFUL OFFICIAL DUTY: The officer must have been acting within the scope of lawful authority. An officer exceeding authority or making an unlawful arrest traditionally gave the defendant the right to resist at common law. This element is where most modern legal evolution has occurred.
2. KNOWLEDGE OF OFFICER STATUS: The defendant must have known, or circumstances must have made it reasonably apparent, that the person was a peace officer. Plain-clothes officers present recurring issues in the case law.
3. RESISTANCE, OPPOSITION, OR OBSTRUCTION: The defendant's conduct must have amounted to resistance, opposition, or obstruction. The threshold — physical force only, or any interference — varies by jurisdiction and statute.
4. INTENT: Most jurisdictions require that the resistance be willful or knowing. Accidental interference generally does not satisfy the offense.

Why It Matters in Research
The lawful arrest rule is the critical research trap. At common law, a person had the right to resist an unlawful arrest, even with force. This rule was widely accepted through the 19th century and is reflected in older case law and historical dictionary sources. Through the mid-to-late 20th century, the majority of states abrogated this common law right by statute, holding that the proper remedy for an unlawful arrest is judicial, not physical resistance. Researchers reading older cases — particularly those cited in historical dictionaries — must account for whether the jurisdiction has modified this rule before treating early holdings as current law.
The offense has expanded significantly in the modern era. Early statutes and cases, including those cited in Black's 2nd Edition, required active, physical opposition. Contemporary statutes in many states reach passive resistance, flight, and verbal interference. This makes historical sources systematically underinclusive when researching current doctrine.
The corpus connection to constitutional law is real and significant: Fourth Amendment excessive force doctrine intersects directly with resisting officer cases. When an underlying stop or arrest is unlawful, the constitutional question and the criminal defense question converge. Researchers should not treat the criminal law materials as self-contained.
Jurisdictional variation is unusually high for this offense. Whether non-physical conduct suffices, whether the common law right to resist unlawful arrest survives, and what mental state is required all differ substantially across states. Treat any general statement about the law of this offense with caution.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) Supplemental defines the offense as "obstructing, opposing, and endeavoring to prevent (with or without actual force) a peace officer, in the execution of a writ or in the lawful discharge of his duty while making an arrest or otherwise enforcing the peace." The parenthetical "with or without actual force" is notable — Black's recognized even in the early period that physical force was not strictly required, contra the popular understanding of the offense.
The three cases Black's cites — Davis v. State (Ga.), Woodworth v. State (Ohio), and Jones v. State (Ala.) — reflect 19th-century state court treatment of the offense and collectively illustrate both the common law framework and the centrality of the lawful duty requirement. The Woodworth decision in particular addressed the Ohio formulation of the offense in the context of writ execution.
What historical dictionary sources miss almost entirely is the evolution of the right to resist unlawful arrest. Black's 2nd Edition does not flag the doctrinal tension that would come to define 20th-century treatment of this offense. Researchers should not infer from the historical sources that the common law rule remains intact — in most jurisdictions, it does not.

Jurisdictional Note
The majority of U.S. states have abolished or significantly limited the common law right to resist even an unlawful arrest by statute. A minority of states retain some form of the right under defined conditions. Federal law does not recognize a general right to resist. Any research on this offense must begin with the controlling jurisdiction's current statute, not the common law baseline.
