The Supreme Court on June 18 narrowed how the federal government may apply the firearms ban covering “unlawful users” of controlled substances, rejecting a broader theory that could have swept in a wide range of gun owners, including some marijuana users. The ruling is likely to become a significant reference point in Second Amendment litigation because it addresses how closely firearm restrictions must fit the government’s asserted public-safety rationale.

At issue was the federal statute that bars certain drug users from possessing firearms.

The U.S. Supreme Court closed out a closely watched cross-border liability fight this week by unanimously rejecting Mexico’s effort to hold American gun manufacturers responsible for firearm trafficking and cartel violence south of the border.

The Southern District of New York has unsealed multiple criminal indictments highlighting two enforcement priorities that continue to draw sustained federal attention: firearms trafficking with cross-border implications and bias-motivated violence. Among the newly announced cases are charges against Malik Bromfield, Faizan Ali, and Kamal Salman tied to the transport of dozens of firearms allegedly intended for attempted smuggling into Canada, as well as a separate hate-crime indictment against Shorai Moore.

While these matters are unlikely to reshape doctrine in the way a major appellate ruling might, they are still significant for practitioners because they reflect where federal investigators and prosecutors are investing resources.
