(1) An individual who has not or is not engaged in the commission of a crime at the time he or she uses deadly
force may use deadly force against another individual anywhere he or she has the legal right to be with no duty to retreat if either of the following applies:
It does, but remember that what we refer to as "the 'Castle Doctrine' law" is composed of five different Public Acts, each providing for some aspect of the protection afforded those who defend themselves :
PA 311 provides a “rebuttable presumption” in a civil or criminal case that a person who defends himself believes that criminal attack is threatened if (1) he is in a dwelling or business, or (2) the criminal is attempting to remove someone from a dwelling, business, or vehicle. This does not apply if the alleged criminal has a legal right to be in the dwelling or business, or if the person defending himself is committing a crime, or if the person entering is a law enforcement officer in the course of his duties.
PA 310 states that a prosecutor may still charge a person who has defended himself if the prosecutor can present to the court evidence that the person did not believe he was threatened with criminal attack. This represents a substantial change from the prior law which puts the burden of proof on the person defending himself to show that he did believe he was subject to criminal attack.
PA 309 says that if a person is anywhere he has a legal right to be, he has no duty to retreat if he believe he is threatened by criminal attack. Note that this differs from the home/business situation where it is presumed that he believes he is subject to criminal attack.
PA 313 is subtle: “Sec. 21c. (1) In cases in which section 2 of the self-defense act does not apply, the common law of this state applies except that the duty to retreat before using deadly force is not required if an individual is in his or her own dwelling or within the curtilage of that dwelling.”
PA 314 states that a person who defends himself (or in defense of another individual) with deadly force or less than deadly force anywhere he has a right to be is immune from civil liability for damages.
PA 312 provides attorney fees to a defendant if a civil suit is filed and the court determines that the defendant is immune from civil liability under PA 314.
