New York justification law distinguishes physical force from deadly physical force. A defensive response must satisfy the conditions in Penal Law Article 35. A person does not gain authority to use any level of force merely because the person subjectively feels threatened. The belief and the degree of force must satisfy the statute.[1]
Physical Force
Section 35.15 generally permits physical force when a person reasonably believes it is necessary to defend against another person's use or imminent use of unlawful physical force. The statute also lists circumstances in which this justification is unavailable or limited, including provocation and initial-aggressor rules.[1]
Deadly Physical Force
Deadly physical force means force readily capable of causing death or another serious physical injury. It is not justified merely because some physical force would be justified. Section 35.15 permits deadly physical force only when a listed predicate applies, including a reasonable belief that the other person is using or about to use deadly physical force or is committing or attempting specified crimes such as kidnapping, specified first-degree sexual offenses, or robbery. Section 35.20 separately governs force involving burglary and premises.[2][1][3]
Retreat Still Matters
When a person relies on the predicate that another is using or about to use deadly physical force, the actor may not use deadly physical force if the actor knows complete personal safety can be achieved by retreating. The statute contains exceptions, including a person in the person's dwelling who was not the initial aggressor and specified police or peace officer circumstances. Other listed deadly-force predicates have their own statutory treatment.[1]
Why Proportionality Is Not a Simple Formula
Deadly force in response to an ordinary non-deadly threat is generally outside the deadly-force predicates, but the analysis cannot stop with that slogan. The statute separately addresses kidnapping, specified sexual offenses, robbery, burglary, retreat, dwelling, provocation, and initial-aggressor questions. A genuine deadly-force threat also does not erase the retreat limitation when that limitation applies.
Practical Rule
- Identify the force or crime the actor reasonably perceived.
- Identify whether the response was physical force or deadly physical force.
- Apply the exact Article 35 predicate, retreat rule, and exception.
- Do not assume that a weapon's presence alone answers whether deadly force was justified.
