From The Truth About Guns:

These “extreme risk protection orders” or “gun violence restraining orders” — whatever they may be called in your state — while grossly unconstitutional, are temporary. Every state where this is law has a specified hearing date, usually about ten to fourteen days after confiscation. At that hearing, the gun owner who’s been temporarily stripped of his or her gun rights has an opportunity to contest the initial complaint in front of a judge. If the judge adjudicates the complaint as unfounded, your rights are restored and you’ll soon get your guns back.
