A federal appeals court Tuesday ruled to keep an Illinois state-wide "assault weapons" ban in effect, denying a request from a business owner who claims the ban is unconstitutional.

The 7th U.S. Circuit Court of Appeals decided to uphold a lower ruling by U.S. District Judge Virginia Kendall, who found the ban to be "constitutionally sound," despite the request for an injunction, the Chicago Sun-Times reported.

Robert Bevis, a firearms store owner in Naperville, is appealing the gun ban signed into law by Gov. J.B. Pritzker on Jan. 10. He contends it fails to meet a legal standard on what guns can and cannot be banned previously set by the U.S. Supreme Court.

Bevis requested the appeals court to block the ban for himself and other business owners affected by the law so that they can resume the sale of the impacted firearms.

GUN RIGHTS GROUP FILES LAWSUIT OVER ILLINOIS ASSAULT WEAPONS BAN

The legislation was introduced in January, six months after a shooting at the Highland Park Fourth of July parade left seven victims dead and wound more than 48 others injured.

The ban includes penalties for anyone who "Carries or possesses… Manufactures, sells, delivers, imports, or purchases any assault weapon or .50 caliber rifle." Anyone who legally possessed such a weapon was required to register it with state police.

It also includes penalties for anyone who "sells, manufactures, delivers, imports, possesses, or purchases any assault weapon attachment or .50 caliber cartridge." It also bans any kit or tools used to increase the rate of fire of a semiautomatic firearm.

The legislation also capped the purchase of certain magazines for several weapons.

Gov. Pritzker, a billionaire Democrat, signed the controversial bill shortly after.

The attorneys who are representing Bevis, who owns and operates Law Weapons & Supply in Naperville, Illinois, argue their client has suffered because of the ban and that he may have to close his business.

In the lower court ruling, Judge Kendall ruled that "because assault weapons are particularly dangerous weapons ... their regulation accords with history and tradition," the Chicago Sun-Times reported.

Bevis’s lawyers dispute this interpretation and instead argue earlier Supreme Court rulings clarify weapons must be found to be "dangerous and unusual" to be banned, per the report.

Because certain rifles are "commonly possessed by law-abiding citizens for lawful purposes," they do meet the legal definition of "not unusual," and thus cannot be banned, they argued, according to the Chicago Sun-Times.

Several legal challenges remain underway against the state’s ban.
