The U.S. Supreme Court has continued to reshape firearms law since its 2022 Bruen ruling set a stricter constitutional test for gun regulations. That debate now extends to disputes involving gun sales and regulation across state lines, where advocates are urging the justices to take up another case. The issue has implications beyond Washington because federal rules on interstate gun transfers affect how states enforce their own firearms laws.
Gun rights groups press for more Supreme Court review
Gun rights advocates intensified that effort on June 26, when Reuters reported that the justices were considering additional Second Amendment appeals for their next term after issuing two rulings that further expanded gun rights. According to Reuters, those pending matters included challenges to assault-style rifle restrictions and a federal ban on licensed dealers selling handguns to adults under 21. The court’s 6-3 conservative majority had just struck down part of a Hawaii handgun law and, days earlier, limited the reach of a federal gun-possession ban tied to certain drug users.
The push for broader review has come from multiple organizations and litigants, not from one single cross-state case alone. Supreme Court docket records show that in United States v. Hemani, No. 24-1234, the court received a large stack of amicus filings in January 2026 from groups including the National Association for Gun Rights, Gun Owners of America, the National Rifle Association and the Firearms Policy Coalition before arguments were heard on March 2. The docket shows the court issued its judgment on June 18, 2026.
What is confirmed is that the justices are being asked to take additional gun cases that could further define the reach of the Second Amendment. What is not yet known is which, if any, cross-state firearms dispute the court may ultimately agree to hear in the coming term. The Supreme Court had not announced a new grant in a dedicated interstate-sales case as of the latest publicly available docket activity reviewed for this report.
For Maryland and other states with detailed firearms regulations, interstate gun rules are tied directly to enforcement and record-keeping. In an August 14, 2024, news release, Maryland Attorney General Anthony Brown said he had joined a 22-attorney-general coalition backing state and federal laws regulating gun sales, including rules on transport across state lines. According to that filing summary, the coalition argued that federal regulation of cross-state gun transfers protects public safety and strengthens state gun laws.
Maryland’s release said 17 states, including Maryland, require licensed firearms dealers to keep detailed inventory and sales records that can assist law enforcement investigations. State officials said those systems help address theft, straw purchases and illegal sales by preserving information about firearm movement and ownership. That is the practical state-level concern behind these interstate disputes: whether firearms purchased or transferred beyond a state’s borders can still be tracked and regulated in ways local law requires.
What remains unclear is whether any future Supreme Court ruling would invalidate only a narrow federal restriction or unsettle a wider range of state practices connected to out-of-state purchases and transfers. Maryland has not identified a new, state-specific list of laws that would immediately change if the justices hear such a case. But state officials have made clear in court filings and public statements that they view federal interstate-transfer rules as a backstop for local enforcement.
The broader reason this issue keeps returning to the justices is the Supreme Court’s Bruen framework, which requires modern gun restrictions to fit the nation’s historical tradition of firearm regulation. Reuters reported on June 26 that legal observers viewed the court’s latest decisions as reinforcing an already demanding standard for governments defending firearms laws. Pepperdine law professor Jacob Charles told Reuters the rulings reflected what he described as the court’s “extreme skepticism” of many newer gun regulations.
At the same time, cross-state firearms disputes often raise a second constitutional question beyond the Second Amendment: how far Congress can go when it relies on its authority over interstate commerce. That issue surfaced in lower-court and petition-stage litigation involving federal gun restrictions tied to whether a firearm crossed state lines at some point in commerce. Those arguments matter because many federal firearms laws are built on that interstate nexus.
For residents, the practical takeaway is that no immediate nationwide rule change has been announced in a new cross-state gun rights case. What is clear is that the justices are still being pressed to clarify both gun-rights doctrine and the limits of federal authority, and recent Supreme Court decisions suggest the court remains deeply engaged with that debate as its next term approaches.
