Torts: defenses; immunity; provide for individual reacting to a riot. Amends 1961 PA 236 (MCL 600.101 - 600.9947) by adding sec. 2922d.

SB 500 amends Michigan's civil procedure law to create a defense for individuals who cause property damage or personal injury (including death) while acting in self-defense against conduct that constitutes a riot. It directly affects people who might face civil lawsuits after reacting to riotous behavior, such as breaking a window to stop a rioter. The bill states that individuals cannot be held liable in civil court if their actions arose from another person's riot conduct, as defined by Michigan law (MCL 752.541). This provision applies specifically to civil lawsuits over property damage or injury, not criminal charges. The bill does not change criminal penalties or create new obligations for law enforcement.
