Sources: 3. Developments: 2. Delaware is experiencing conflicting legal developments regarding firearm regulations. A federal judge, U.S. District Judge Maryellen Noreika, struck down state bans on the private manufacturing of firearms and the possession of unserialized ‘ghost guns’, ruling these provisions violate the Second Amendment. However, the judge upheld prohibitions on the distribution of unfinished firearm frames or receivers and the ban on disseminating computer-aided design (CAD) files used for 3D printing gun parts. In a separate ruling, the Delaware Supreme Court voted 4-1 to reinstate House Bill 451. This law restricts the purchase and possession of most firearms to individuals aged 21 and older, reversing a previous Delaware Superior Court decision that had found the age limit unconstitutional. Attorney General Kathy Jennings described the reinstatement as a victory for gun safety intended to reduce violence and accidents among young adults. ## Timeline ### 2026-09-09: Delaware courts issue split rulings on firearm regulations Delaware courts have issued conflicting rulings on gun laws: a federal judge struck down bans on ghost guns and home manufacturing, while the state Supreme Court upheld age limits for firearm ownership. 2 sources. https://clstr.news/cluster/delaware-courts-issue-split-rulings-on-firearm-regulations ### 2026-09-08: Delaware courts uphold absentee voting and campaign finance laws Delaware courts have upheld the state’s permanent absentee voting law and rejected an appeal to overturn campaign finance disclosure rules for third-party advertisers. 2 sources. https://clstr.news/cluster/delaware-courts-uphold-absentee-voting-and-campaign-finance-laws --- Cite as: Delaware firearm regulation legal rulings.
