Everytown Law Files Amicus Brief in Support of California’s Prohibition on Large-Capacity Magazines (Duncan v. Becerra)

July 23, 2019

SAN DIEGO, Calif. – Everytown filed this amicus brief in the United States Court of Appeals for the Ninth Circuit in defense of California’s prohibition on large-capacity magazines. This brief details the long history of regulating especially dangerous weapons, including a century of restrictions on semiautomatic firearms capable of firing a large number of rounds without reloading. It also demonstrates the circularity and illogic of the “common use” test argued for by plaintiffs, based upon nationwide sales and manufacturing figures, which cannot be reconciled with either the Supreme Court’s decision in District of Columbia v. Heller or common sense, and is inconsistent with core principles of federalism. And, relying on Everytown’s own research, this brief further explains the substantial relationship between regulating large-capacity magazines and California’s undeniably important interest in preventing and mitigating both mass shootings and day-to-day gun violence.
