The United States Supreme Court will not decide until at least Monday whether or not to hear the case of Arie Friedman vs. the City of Highland Park , a challenge to the city's ban on assault weapons, the Chicago Tribune reports.

Arie Friedman, a Lincolnshire pediatrician, sued the city after an ordinance passed banning semi-automatic "assault weapons" that carry more than 10 rounds. A federal appeals court upheld the city ordinance on a 2-1 vote.

"Assault weapons with large-capacity magazines can fire more shots, faster, and thus can be more dangerous in aggregate," the appeals court's majority opinion read. "Why else are they the weapons of choice in mass shootings?"
