duty to retreat or avert a violent encounter, or by even granting a blanket rebuttable presumption of required killing in defense of life. Where principles are statutized in a penal code, a homicide may be excused criminally, but be a wrongful death civilly. In a strict sense, simple justifiable homicide in self-defense which happens to occur inside one's home is actually distinct as a matter of law from castle doctrine's no duty to retreat in defense of one's domicile. Self-defense protects life while castle doctrine defends estate. While most American states forbid the use of force in the recovery of possession of land, a minority of jurisdictions do invoke pure castle doctrine which unconditionally authorizes violent self-help in protection of one's domicile. States with weak or no specific castle law These states uphold castle doctrine in general, but may rely on case law instead of specific legislation, may enforce a duty to retreat, and may impose specific restrictions on the use of deadly force: District of Columbia Nebraska - a bill was introduced in January 2012 that allowed deadly force against a person who broke into a house or occupied vehicle or who tried to kidnap someone from a house or vehicle; however, the bill was revised to include only an affirmative defense from lawsuits pertaining to justifiable use of force. New Mexico - Limited Castle Doctrine for self-defense inside one's home established by court precedence in State v. Couch (1946). No civil immunity from potential lawsuits by the aggressor or surviving relatives. In 2011, two bills (House Bill 228 and Senate Bill 29) would have granted civil immunity to individuals who lawfully use lethal force in self-defense, both bills died in their respective chambers of the New Mexico Legislature. Vermont Situation in U.S. territories Outside the United States Australia Australian states have differing self-defence laws. Under South Australian law, the general defence appears in s15(1) Criminal Law Consolidation Act 1935 (SA) for defending a person's life, and s15A(1) for defending property, subject to a hybrid test, i.e. the defendant honestly believed the threat to be imminent and made an objectively reasonable and proportionate response to the circumstances as the accused subjectively perceived them. In July 2003, South Australia's Rann Government introduced laws allowing householders to use "whatever force they deem necessary" when confronted with a home invader. Householders who kill or injure a home invader escape prosecution provided they
