The Florida Supreme Court Wednesday granted the National Rifle Association Freedom Action Foundation permission to weigh in on a closely watched case involving the retroactive application of a controversial change to Florida’s “Stand Your Ground” law.

The case appeared to have caught the attention of the NRA nonprofit because it hinges on which party should shoulder the burden of proof in use-of-force cases, and whether a change in the law in 2017 could retroactively apply to older proceedings.
