Executive summary
Federal courts in Oregon have split legal terrain since 2023: U.S. District Judge Karin Immergut ruled Measure 114’s ban on magazines over 10 rounds and its permit‑to‑purchase regime are constitutional under the U.S. Constitution [1] and that decision was appealed to the Ninth Circuit [2]. Parallel state‑court litigation produced a contrary ruling below that blocked the law from taking effect and raised Oregon‑constitutional issues, setting up a years‑long fight with overlapping federal and state appeals [3] and an Oregon Court of Appeals decision in March 2025 finding the measure facially constitutional under the state constitution [4] [3].
1. A federal bench found Measure 114 fits the Second Amendment framework
In July 2023 U.S. District Judge Karin Immergut issued a detailed 122‑page opinion upholding Measure 114 — which bans sale or manufacture of magazines holding more than 10 rounds and requires permits to purchase firearms — ruling those provisions are consistent with the Second Amendment’s “historical tradition” test set by the U.S. Supreme Court’s Bruen decision [5] [6]. Immergut concluded large‑capacity magazines are “not commonly used for self‑defense” and that permit‑to‑purchase requirements do not facially violate the Second Amendment [7] [2].
2. The federal ruling did not end the legal fight — appeal followed immediately
Gun store owners and gun‑rights groups appealed Immergut’s July 2023 decision to the Ninth Circuit, meaning enforcement in Portland remained unsettled while the federal appeal proceeded [2]. Reporting at the time and subsequent coverage noted the federal ruling was expected to be challenged up the appeals ladder, potentially to the U.S. Supreme Court [6] [8].
3. State courts mounted a parallel and at times conflicting legal track
While Immergut addressed the U.S. Constitution, a Harney County circuit judge examined Measure 114 under the Oregon Constitution and in November 2023 ruled the measure violated state constitutional protections, blocking it from taking effect [9] [3]. That split — federal approval, state invalidation — left practical enforcement in Portland frozen for years as litigants pursued appeals in both systems [9] [10].
4. The appeals phase shifted the balance again in 2025
The Oregon Court of Appeals in March 2025 reversed the Harney County ruling, declaring Measure 114 facially constitutional under the state constitution and restoring the state‑law pathway for the measure [4] [3]. Coverage notes the appeals court found the lower judge applied an incorrect legal framework and that the state ruling cleared another major obstacle facing Measure 114 [4] [3].
5. Enforcement in Portland remained conditioned on court outcomes and implementation logistics
Even after the federal decision, Judge Immergut allowed some administrative delays — notably postponing permit implementation until systems were ready — and the Oregon Supreme Court’s early procedural rulings left Measure 114 blocked from immediate effect in practice [10] [11]. Multiple sources emphasize that for Measure 114 to be fully implemented the state needed simultaneous victories in federal and state courts and administrative readiness from state agencies [8] [11].
6. How courts framed the legal question — historical tradition vs. state constitutional text
Federal analysis followed the Supreme Court’s Bruen test, focusing on historical analogues for weapons regulation and whether modern restrictions are consistent with that history [5] [6]. State litigation turned on Oregon’s own constitutional language and history; the Harney County judge and later the Court of Appeals applied different interpretive frameworks, producing divergent outcomes until the appeals court ruling in 2025 [9] [4].
7. What this means for Portland law enforcement and public policy
Because federal and state rulings conflicted at times, Portland’s ability to enforce Measure 114 — seize prohibited magazines, deny or require permits at point of sale — depended not just on federal precedent but on the state‑court timeline and state administrative readiness [11] [10]. Local enforcement agencies continued traditional gun‑violence strategies (Ceasefire, focused policing) while courts sorted constitutional questions [12] [13]. Available sources do not mention specific day‑to‑day enforcement changes in Portland immediately following the 2023 federal ruling beyond the litigation and administrative delays noted (not found in current reporting).
Limitations and competing viewpoints: reporting shows federal courts framed the issue through Bruen’s historical test and found Measure 114 constitutional [6] [1], while state‑court challengers argued Oregon’s constitution yielded a different result and won in trial court [9]. Advocates for the law said it protects public safety; opponents called it an erosion of gun rights and appealed adverse rulings [1] [3]. My account relies solely on contemporaneous reporting cited above and does not attempt to resolve unsettled appeals or administrative decisions after March 2025 — those developments are beyond the sources provided (not found in current reporting).
