In a 40-page order issued March 9, the U.S. Court of Appeals for the 11th Circuit denounced the “disturbing regularity” of mass shootings in nationwide schools and upheld a Florida law prohibiting those under 21 from purchasing a firearm.

Following the shooting at Marjory Stoneman Douglas High School in Parkland in 2018 that killed 17, the Florida Legislature drafted a public safety act named after the school, which banned the sale of firearms to 18-20 year-olds. The NRA swiftly challenged the law in court, claiming it violated the Second and Fourteenth Amendments.
