I know this is a state forum and the title is US Constitution, but the question I have is directed more at the state level in regards to reciprocity issues. Is anyone aware of any case involving the following Section from the US Constitution: "Article IV Section 1. Full faith and credit shall be given in each state to the public acts, records, and judicial proceedings of every other state. And the Congress may by general laws prescribe the manner in which such acts, records, and proceedings shall be proved, and the effect thereof." Just wondering if this angle has already been used. For example, if someone with a GFL were in any other state, would this section mean that the other state would have to honor the GFL just as they would a driverâ€™s license or marriage license? Is there some law I am missing that would disqualify a firearms license/permit/etc. from being covered under this?
