The law raised the minimum age to purchase rifles and other long guns from 18 to 21, and the NRA challenged it. Some GOP lawmakers in the Florida House are pushing to repeal the law this spring.

The 8-4 ruling by the 11th U.S. Circuit Court of Appeals came after seven years of legal wrangling in the National Rifle Association’s challenge to a 2018 law passed after a mass shooting at Parkland’s Marjory Stoneman Douglas High School that killed 17 students and faculty members.

Florida House Republicans back a proposal that would repeal part of a law that prevents people under the age of 21 from buying rifles and shotguns.
