Stand Your Ground

A stand-your-ground law states that a person may use force in self-defense when there is reasonable belief of a threat, without an obligation to retreat first. In some cases, a person may use deadly force in public areas without a duty to retreat. Under these legal concepts, a person is justified in using deadly force in certain situations and the "stand your ground" law would be a defense or immunity to criminal charges and civil suit. The difference between immunity and a defense is that an immunity bars suit, charges, detention and arrest. A defense permits a plaintiff or the state to seek civil damages or a criminal conviction. More than half of the states in the United States have adopted the Castle doctrine, stating that a person has no duty to retreat when their home is attacked. Some states go a step further, removing the duty of retreat from any location. "Stand Your Ground", "Line In The Sand" or "No Duty To Retreat" laws thus state that a person has no duty or other requirement to abandon a place in which he has a right to be, or to give up ground to an assailant. Under such laws, there is no duty to retreat from anywhere the defender may legally be. Other restrictions may still exist; when in public, a person must be carrying the firearm in a legal manner, whether concealed or openly.

"Stand your ground" governs U.S. federal case law in which self-defense is asserted against a charge of criminal homicide. The Supreme Court ruled in Beard v. U.S. (158 U.S. 550 (1895)) that a man who was "on his premises" when he came under attack and "...did not provoke the assault, and had at the time reasonable grounds to believe, and in good faith believed, that the deceased intended to take his life, or do him great bodily harm...was not obliged to retreat, nor to consider whether he could safely retreat, but was entitled to stand his ground."

United States

Many states have some form of Castle Doctrine or Stand Your Ground law. Alabama, Alaska, Arizona, California, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Michigan, Mississippi, Missouri, Montana, New Hampshire, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia, Wisconsin and Wyoming have adopted Castle Doctrine statutes, and other states (Iowa, Nebraska, Virginia, and Washington) are currently considering "Stand Your Ground" laws of their own.

Some of the states that have passed or are considering "stand your ground" laws already implement "stand your ground" principles in their case law. Indiana and Georgia, among other states, already had "stand your ground" case law and passed "stand your ground" statutes due to possible concerns of the case law being replaced by "duty to retreat" in later court rulings. Other states, including Washington, have "stand your ground" in their case law but have not adopted statutes; West Virginia had a long tradition of "stand your ground" in its case law before codifying it as a statute in 2008. These states did not have civil immunity for self defense in their previous self defense statutes.
