From the NRA:
In one of the strongest judicial statements in favor of the Second Amendment to date, Judge Roger T. Benitez of the U.S. District Court for the Southern District of California determined on Friday that California’s ban on commonly possessed firearm magazines violates the Second Amendment.
The case is Duncan v. Becerra.
The NRA-supported case had already been up to the U.S. Court of Appeals for the Ninth Circuit on the question of whether the law’s enforcement should be suspended during proceedings on its constitutionality. Last July, a three judge panel of the Ninth Circuit upheld Judge Benitez’s suspension of enforcement and sent the case back to him for further proceedings on the merits of the law itself.
Judge Benitez rendered his opinion late Friday afternoon and handed Second Amendment supporters a sweeping victory by completely invalidating California’s 10-round limit on magazine capacity. “Individual liberty and freedom are not outmoded concepts,” he declared.
In a scholarly and comprehensive opinion, Judge Benitez subjected the ban both to the constitutional analysis he argued was required by the U.S. Supreme Court in District of Columbia v. Heller and a more complicated and flexible test the Ninth Circuit has applied in prior Second Amendment cases.
