Maine Castle Doctrine and Stand Your Ground Laws

Castle Doctrine & Stand Your Ground Laws in Maine

Maine's use-of-force laws are codified in Title 17-A, Chapter 5 of the Maine Revised Statutes. Maine has a strong Castle Doctrine and a qualified duty to retreat outside the dwelling — deadly force outside the home is not justified if the person knows they can retreat with complete safety.

Use of Non-Deadly Force in Self-Defense (17-A M.R.S. § 108(1))

A person is justified in using reasonable non-deadly force to defend themselves or a third person from the imminent use of unlawful, non-deadly force, to the degree they reasonably believe necessary.

Non-deadly force is NOT justified if:

• The person provoked the other's use of unlawful non-deadly force with the purpose to cause physical harm (§ 108(1)(A))
• The person was the initial aggressor, unless they withdrew and effectively communicated that withdrawal, but the other person continued (§ 108(1)(B))
• The force was the product of combat by agreement not authorized by law (§ 108(1)(C))

Use of Non-Deadly Force Against Law Enforcement (17-A M.R.S. § 108(1-A))

A person is not justified in using non-deadly force against a law enforcement officer the person knows or reasonably should know is attempting to effect an arrest or detention, regardless of whether the arrest or detention is legal. However, a person may use non-deadly force they reasonably believe necessary to defend against a law enforcement officer who uses non-deadly force not justified under § 107(1).

(Added by PL 1997, c. 351, § 1)

Use of Deadly Force in Self-Defense (17-A M.R.S. § 108(2))

A person is justified in using deadly force when they reasonably believe it necessary and reasonably believe the other person is:

1. About to use unlawful, deadly force against the person or a third person (§ 108(2)(A)(1)); or
2. Committing or about to commit a kidnapping, robbery, or gross sexual assault (violation of § 253(1)(A)) against the person or a third person (§ 108(2)(A)(2))

Deadly force is also justified in a dwelling place when the person reasonably believes:

• The other person has entered, is attempting to enter, or has surreptitiously remained without license or privilege; and
• Deadly force is necessary to prevent the infliction of bodily injury upon the person or a third person present in the dwelling (§ 108(2)(B))

Duty to Retreat — Qualified (17-A M.R.S. § 108(2)(C)(3))

Maine is not a full Stand Your Ground state. Deadly force under § 108(2)(A) is not justified if the person knows they or the third person can, with complete safety:

• Retreat from the encounter — except that there is no duty to retreat if the person is in their dwelling place and was not the initial aggressor (§ 108(2)(C)(3)(a))
• Surrender property to a person asserting a colorable claim of right (§ 108(2)(C)(3)(b))
• Comply with a demand to abstain from an act the person is not obliged to perform (§ 108(2)(C)(3)(c))

Practical effect: The "complete safety" standard is high. A person must retreat only if they know retreat is possible with complete safety. Inside the dwelling, there is no duty to retreat at all (provided the person was not the initial aggressor). This makes Maine a strong Castle Doctrine state with a limited retreat obligation outside the home.

Provocateur Exceptions (17-A M.R.S. § 108(2)(C)(1)–(2))

Deadly force is not justified if:

• The person provoked the other to use unlawful deadly force with the intent to cause physical harm (§ 108(2)(C)(1))
• The person knows the person against whom deadly force is directed intentionally and unlawfully provoked it (§ 108(2)(C)(2))

Prohibition on "Panic" Defense (17-A M.R.S. § 108(3))

A person is not justified in using force against another based solely on the discovery of, knowledge about, or potential disclosure of the victim's actual or perceived gender, gender identity, gender expression, or sexual orientation — including where the victim made an unwanted nonforcible romantic or sexual advance, or where the parties dated or had a relationship.

(Added by PL 2019, c. 462, § 2)

Castle Doctrine — Defense of Premises (17-A M.R.S. § 104)

Non-deadly force (§ 104(1)): A person in possession or control of premises, or licensed/privileged to be there, may use non-deadly force to the extent reasonably believed necessary to prevent or terminate a criminal trespass.

Deadly force — arson (§ 104(2)): Deadly force is justified to the extent reasonably believed necessary to prevent an attempt to commit arson on the premises.

Deadly force — dwelling place (§ 104(3)): A person in possession or control of a dwelling place (or licensed/privileged to be therein) may use deadly force when:

• The circumstances in § 108 apply (§ 104(3)(A)); or
• The person reasonably believes deadly force is necessary to prevent or terminate a criminal trespass where the other person:
  1. Has entered, is attempting to enter, or has surreptitiously remained in the dwelling without license or privilege; and
  2. Is committing or is likely to commit some other crime within the dwelling (§ 104(3)(B))

Demand requirement (§ 104(4)): Before using deadly force under § 104(3)(B), the person must first demand that the trespasser leave and the trespasser must fail to immediately comply — unless the person reasonably believes making the demand would be dangerous to themselves or a third person.

Defense of Property (17-A M.R.S. § 105)

A person may use non-deadly force when reasonably believed necessary to prevent unlawful taking of property, criminal mischief, or to retake property immediately following its taking. Deadly force is not justified solely in defense of property.
