Assembly passes 'Second Amendment sanctuary' bill that would bar enforcement of federal gun restrictions Molly Beck, Milwaukee Journal Sentinel MADISON - Wisconsin gun owners would not be subject to federal firearm laws under legislation up passed by Republicans and one Democrat in the state Assembly on Wednesday. But the idea has been deemed unconstitutional in the past in other states because state law cannot override conflicting federal law under the U.S. Constitution. Rep. Tip McGuire, D-Kenosha, said the legislation is inferior to the Second Amendment and "in fact undermines the Constitution that we all swore an oath to uphold."
