In criminal cases alleging the use of force a defendant may seek immunity from prosecution. Today, this is called Stand Your Ground, but it has always been true that self-defense is a viable defense to any use of force case. A person seeking immunity has the burden to put forth evidence that the use of force alleged was reasonable against another's imminent use of unlawful force.
Though the Stand Your Ground law was enacted a few years ago, the burden of proof had never been ultimately decided by the Florida Supreme Court. The procedure in a Motion to Dismiss based upon immunity had been established.
