Judge Roger T. Benitez permanently enjoined California’s ban on standard capacity magazines.

From the Volokh Conspiracy:

The 86-page opinion is the most thorough judicial analysis thus far of the magazine ban question. The opinion is founded on a careful analysis of the record, and thus provides an excellent basis for future appellate review on the merits, perhaps one day by the U.S. Supreme Court.

Covering all bases, the opinion analyzes the confiscation law under a variety of standards of review. First is the standard favored by Judge Benitez, what he calls “The Supreme Court’s Simple Heller Test.” In short, magazines over 10 rounds are plainly “in common use” “for lawful purposes like self-defense.” Ergo, they may not be confiscated. The analysis is similar to then-Judge Kavanaugh’s dissenting opinion in the 2011 Heller II case in the D.C. Circuit.

I’ve heard the terms scathing and comprehensive being thrown around for the judge’s opinion

I don’t doubt we still have a tough Raif with the rest of the 9th Circuit, but it’s a win.
