Self Defense And The Castle Doctrine
Idaho Code § 19-202A and Idaho Code § 18-4009 — no duty to retreat, and a presumption at home, at work and in the car
No duty to retreat. A person need not retreat from any place the person has a right to be, and may stand their ground and defend themselves or another with all force and means that would appear necessary to a reasonable person in a similar situation, without the benefit of hindsight.
A person defending themselves or another need not wait to learn whether the danger is real, and may act on appearances as a reasonable person would. In a prosecution for the use of force, the prosecution must prove beyond a reasonable doubt that it was not justifiable.
The presumption. A person using force in defense of a home, a place of business or employment, or an occupied vehicle is presumed to have acted reasonably against someone whose entry is unlawful and made by force, violently, by stealth, or to commit a felony.
Homicide is justifiable when resisting an attempt to murder, to commit a felony or to do great bodily injury, and in defense of the home, workplace or occupied vehicle against one who intends a felony by violence or surprise. A person who started the fight must in good faith have tried to decline further struggle.
The legislature has said these sections carry the castle doctrine and stand your ground rules from Idaho's case law and jury instructions. Whether force was justified in a particular case is a question for a jury and a licensed Idaho attorney.
