A federal lawsuit in Buffalo on Tuesday asks the court to block the Erie County district attorney and head of New York State Police from enforcing the state’s conceal carry provisions that went into effect earlier this month.

The plaintiffs, the Firearms Policy Coalition of Las Vegas, Nevada, the Second Amendment Foundation of Washington state, and the two New Yorkers who are licensed firearms carriers assert that the new law deprives them of their civil rights to keep and bear arms under the U.S. Constitution’s 2nd and 14th Amendments.
