Republican legislators are rallying behind nullification legislation that would void unconstitutional infringements on the right to keep and bear arms, even providing prison time for any federal agents who may try to enforce Washington, D.C., gun control in the state. Lawmakers expect it to pass.

The new bill, H.B. 0104 or the “Firearms Protection Act,” would nullify any new federal infringements on the constitutionally protected gun rights of state residents — who enjoy some of the lowest crime rates while being among the most heavily armed people in America. Unconstitutional federal gun registration schemes, as well as restrictions on semi-automatic guns or standard-capacity magazines, would also be nullified under the legislation.

There are teeth in the proposed law too: Any federal official attempting to enforce unconstitutional statutes or decrees infringing on gun rights passed after January 1 of this year would be charged with a felony. If convicted, criminal officials would be punished by up to five years in state prison and a $5,000 fine. The legislation also authorizes the state attorney general to defend citizens of Wyoming if federal authorities seek prosecutions under unconstitutional gun control rules.
