nullification

Amendment 5, a proposed Missouri constitutional amendment on the Aug. 5 ballot, seeks to protect further the right to bear arms.

"It's going to strengthen the protection that the right to keep and bear arms under the Missouri constitution," said Allen Rostron, a constitutional law professor at the University of Missouri-Kansas City. "Everybody is familiar with the Second Amendment of the U.S. Constitution, of course, but there's also a provision in the Missouri state Constitution that guarantees a right to keep and bear arms, and this is designed to strengthen that right."

The National Rifle Association is taking some heat from two Missouri state senators over legislation to nullify federal gun control laws within the state.

Missouri Attorney General Chris Koster is raising concerns about legislation attempting to nullify some federal gun-control laws.

Koster sent a letter Tuesday (.pdf) to lawmakers warning that the bill contains "flawed public policy."

The Republican-led Legislature is to meet Sept. 11 to consider overriding Democratic Gov. Jay Nixon's veto of the legislation.
