In yet another major win for smart gun laws, the Seventh Circuit ruled this week that an ordinance adopted by Highland Park, Illinois, prohibiting assault weapons and large capacity ammunition magazines (LCAMs) does not violate the Second Amendment.

We were proud to file an amicus brief in the case, Friedman v. City of Highland Park, with the help of Katten Muchin Rosenman LLP, this year’s recipient of the Law Center’s Richard W. Odgers Pro Bono Partner Award. Highlighting the devastating role that assault weapons and large capacity magazines play in mass shootings and other gun crimes, the brief argued that the city’s prohibition on these military-style weapons is consistent with the Second Amendment.

The Law Center was founded in the wake of an assault weapon rampage, where the shooter also used large capacity magazines to kill nine and injure six at a law firm at 101 California Street in San Francisco in 1993. These weapons make it significantly easier for people to shoot more rounds more quickly, increasing the number of victims. Large capacity ammunition magazines are used disproportionately in mass shootings like those in Newtown, Aurora, Tucson, and Virginia Tech.

In a 2–1 decision authored by the prolific appellate judge, Frank Easterbrook, the Seventh Circuit agreed with the Law Center’s assessment of the case. “That laws similar to Highland Park’s reduce the share of gun crimes involving assault weapons is established by data,” Judge Easterbrook wrote. “A ban on assault weapons and large capacity magazines… may reduce the carnage if a mass shooting occurs.”

Also of great importance to the court was the ordinance’s minimal impact on self-defense. “Unlike the District of Columbia’s ban on handguns [at issue in the landmark Heller case], Highland Park’s ordinance leaves residents with many self-defense options.” As a result, the court concluded that the city’s prohibition on assault weapons and large capacity ammunition magazines does not violate the Second Amendment.

This victory yet again demonstrates the unprecedented momentum across the country for common-sense gun laws. The ruling is the second so far this year regarding prohibitions on military-style weapons, following the Ninth Circuit’s recent ruling upholding a Sunnyvale, CA, ban on possessing large capacity magazines. Several similar cases are currently pending in federal appellate courts across the country, including the Second, Fourth, and Tenth Circuits. The Law Center filed amicus briefs in each of these cases as part of our commitment to fight for smart gun laws that will save countless lives. We expect positive outcomes in these cases–stand with us in the fight for safer communities for everyone and become a member today.
