West Virginia and 25 other states have asked the Supreme Court to strike down the District’s ban on magazines that hold more than 10 rounds of ammunition, saying it’s an unlawful ban on firearms.

Led by West Virginia Attorney General John B. McCuskey, the states said Tuesday in an amicus brief that the restriction infringes on the right to bear arms.

“Until the Supreme Court weighs in, cities will continue passing these far-reaching bans on guns and ammo — knowing that certain lower courts will continue to push the agenda to limit our Second Amendment rights,” Mr. McCuskey said in a press release. “This must be stopped and we are asking the Supreme Court to once and for all declare the legality of firearm magazines protected under the Second Amendment.”

The case, Andrew Hanson v. District of Columbia, asks the justices to decide if banning large capacity magazines runs afoul of the Second Amendment.

Joining West Virginia in the amicus brief: Arkansas, Alabama, Alaska, Idaho, Florida, Georgia, Iowa, Indiana, Kentucky, Kansas, Mississippi, Louisiana, Missouri, Nebraska, Montana, North Dakota, New Hampshire, Oklahoma, Ohio, South Dakota, South Carolina, Utah, Virginia, Texas and Wyoming.

According to court documents, Americans have “hundreds of millions of magazines that can hold more than ten rounds of ammunition.”

Four of the five best-selling pistols have magazines that hold more than 10 rounds, according to the challenger’s petition.

The U.S. Court of Appeals for the D.C. Circuit ruled against the challenger, reasoning that magazines with more than 10 rounds are “particularly dangerous” and can be banned under the Second Amendment.

Possession of magazines that hold more than 10 rounds of ammunition is a felony in the District.
