Do you know the citation? "in any court" would suggest that "indictment" would include a state charge. Nonetheless, I think this law would likely be found unconstitutional. First, it eliminates a constitutional right without due process. Second, it does so whether or not the indictment relates in any way to firearms and/or it lacks any procedure for determining whether say injunctive relief or a restraining order would be appropriate (think of a red flag law where a person actually threatened another person with a gun and a court determines that the perp should be prohibited from possessing guns while out on bail). I think it exceeds the scope of New York State Rifle & Pistol Association v. Bruen for that reason alone.
