The Republican-controlled Missouri legislature is expected to enact a statute next month nullifying all federal gun laws in the state and making it a crime for federal agents to enforce them there. A Missourian arrested under a federal firearms statute would even be able to sue the arresting officer, The New York Times reports.

The measure was vetoed last month by Gov. Jay Nixon (D) as unconstitutional. But the legislature will seek to override the veto when it gathers again Sept. 11. Most experts, however, say the courts will strike down the measure.

The movement, called “nullification,” has bloomed in recent years over a host of other issues, including medical marijuana and the new health care law.
