The Second Amendment Foundation’s amicus brief in Darius Duvall v. State of Maryland is more than a procedural filing—it’s a direct challenge to the notion that a law-abiding citizen’s right to bear arms evaporates the moment he crosses an invisible state line. Maryland’s refusal to honor valid out-of-state permits creates a patchwork of “rights” that only exist inside certain borders, turning the Second Amendment into a privilege granted by geography rather than a constitutional guarantee. By urging the state’s highest court to take the case, SAF is forcing Maryland to confront whether its non-recognition policy can survive the post-Bruen landscape, where historical tradition—not modern policy preferences—must justify restrictions on the right to carry.

For the broader 2A community, the stakes extend far beyond Duvall’s individual permit. A ruling that Maryland must respect sister-state licenses would chip away at the remaining non-reciprocal holdouts and reinforce the principle that the right to self-defense doesn’t require a permission slip from the destination state. Conversely, if the court declines review or upholds the status quo, it would signal that states can continue to nullify lawfully issued carry permits simply by drawing a line on a map—an outcome that would embolden other anti-carry jurisdictions and complicate travel for millions of permit holders. Either way, the Maryland Supreme Court’s decision will serve as an early indicator of how aggressively state courts intend to apply Bruen’s history-and-tradition test to interstate carry, setting the tone for similar challenges nationwide.
