California has long been at the forefront of stringent gun control legislation, but a recent legal battle, Rhode v. Bonta, has sent shockwaves through the state’s regulatory landscape, particularly concerning ammunition purchases. This case, initially heard by the 9th Circuit Court of Appeals in 2025, delivered a significant blow to California’s restrictive ammunition laws, striking down the state’s requirement for background checks on ammo sales. While the case is currently undergoing an en banc rehearing, its initial ruling established a potent pro-Second Amendment precedent, asserting that ammunition restrictions are just as subject to constitutional scrutiny as firearms themselves.
For years, gun rights advocates in California have grappled with an ever-expanding web of regulations designed to limit firearm ownership and use. Among these, the state’s ammunition background check requirement, implemented in 2019, has been a particular point of contention. This law mandated that every ammunition purchase go through a state background check, requiring buyers to pay a fee and wait for approval. Proponents argued it was a vital public safety measure, intended to prevent prohibited persons from acquiring ammunition. Opponents, however, saw it as an unconstitutional burden on law-abiding citizens’ Second Amendment rights, a costly and inefficient hurdle that did little to deter criminals but significantly impacted responsible gun owners.
The Genesis of Rhode v. Bonta
The lawsuit, filed by plaintiffs including the California Rifle & Pistol Association (CRPA) and several individuals, challenged California’s ammunition background check laws, along with other related restrictions like the prohibition on importing ammunition purchased out-of-state. The case was named after the lead plaintiff, Kim Rhode, an Olympic medalist and competitive shooter, and Rob Bonta, California’s Attorney General. The heart of their argument was that these regulations violated the Second Amendment right to keep and bear arms, as affirmed by landmark Supreme Court decisions like Heller and Bruen.
The plaintiffs contended that requiring a background check for every single ammunition purchase placed an undue burden on individuals seeking to exercise their constitutional rights. They highlighted the practical difficulties, such as long lines, system failures, and the recurring fees, which effectively priced out or severely inconvenienced many law-abiding citizens, particularly those in rural areas or with limited access to authorized vendors. Furthermore, they argued that ammunition is inextricably linked to the right to bear arms; without access to ammunition, the right to own a firearm becomes meaningless. Therefore, any restriction on ammunition must be subject to the same strict scrutiny applied to firearm restrictions.
The Initial Ninth Circuit Ruling (2025)
In a momentous decision delivered in 2025, a three-judge panel of the Ninth Circuit Court of Appeals sided with the plaintiffs, effectively striking down California’s ammunition background check law. The court’s majority opinion, echoing the principles laid out in New York State Rifle & Pistol Association v. Bruen (2022), affirmed that the Second Amendment protects an individual’s right to keep and bear arms for self-defense, and that this right extends to the means of exercising it—namely, ammunition.
Applying Bruen’s Historical Test
The Ninth Circuit applied the historical test established by Bruen, which requires states to demonstrate that a challenged firearm regulation is consistent with the nation’s historical tradition of firearm regulation. The court found that California failed to meet this burden. It scrutinized historical analogues presented by the state and concluded that there was no historical tradition in American law that supported a modern-day requirement for background checks on every ammunition purchase. The court rejected the state’s arguments that such checks were comparable to historical regulations on gunpowder storage or sales to indigenous populations, finding these analogies to be inapposite and insufficient to justify the contemporary restrictions.
Judge Benitez’s Influence and Precedent
While specific details of the 2025 ruling aren’t always public until final, it’s highly probable that this decision built upon previous rulings by judges known for robust Second Amendment interpretations. Judge Roger Benitez, a federal judge in the Southern District of California, has a history of striking down California gun laws, often with strong constitutional reasoning. His earlier rulings on high-capacity magazines and assault weapons bans set a precedent for a rigorous application of the Second Amendment, often finding modern restrictions to be inconsistent with historical tradition. The Rhode v. Bonta ruling likely mirrored this judicial philosophy, solidifying the idea that the right to bear arms is a fundamental individual right that cannot be unduly infringed upon by state legislatures.
The panel’s decision emphasized that the state’s interest in public safety, while legitimate, cannot override constitutional rights without a compelling historical basis. It underscored that mere assertions of safety benefits are insufficient; the state must demonstrate that the law fits within a historical tradition of firearm regulation that comports with the Second Amendment’s original public meaning. The court found California’s ammunition background check regime to be a novel and unconstitutional burden that did not withstand this scrutiny.
Immediate Implications for California Gun Owners
The immediate aftermath of the 2025 ruling brought a sense of relief and victory to California gun owners and Second Amendment advocates. For a brief period, the cumbersome background check requirement for ammunition purchases was lifted, simplifying the process for law-abiding citizens to acquire the necessary components for shooting sports, hunting, and self-defense. This temporary reprieve allowed many to purchase ammunition without the previous delays, fees, and bureaucratic hurdles. It was celebrated as a recognition that the right to keep and bear arms includes the right to acquire the means to make those arms functional.
A Broader Pro-2A Precedent
Beyond the practical implications for ammunition sales, the initial ruling in Rhode v. Bonta sent a powerful message: ammunition restrictions are not immune from Second Amendment challenges. This decision signaled a growing judicial trend, post-Bruen, to apply a more rigorous standard to all forms of gun control, treating ammunition as an integral part of the right to bear arms. This meant that future attempts by states to regulate ammunition would face higher hurdles and stricter scrutiny, requiring a demonstration of historical consistency rather than just a public safety rationale.
The En Banc Rehearing (March 2026)
However, the legal battle for ammunition rights is far from over. In March 2026, the Ninth Circuit Court of Appeals granted California’s petition for an en banc rehearing of Rhode v. Bonta. This means that a larger panel of judges, typically 11 to 29 of the active judges on the court, will reconsider the case. An en banc review is a rare occurrence, usually granted when a case involves a question of exceptional importance or when it is necessary to secure or maintain uniformity of the court’s decisions.
What an En Banc Rehearing Means
-
Review of Panel Decision: The full court (or a larger panel) will review the three-judge panel’s decision, effectively vacating the earlier ruling. This means the initial victory for gun rights advocates is paused or potentially reversed.
-
Broader Judicial Perspective: A larger group of judges, often with diverse legal philosophies, will weigh in on the constitutional questions. This can lead to a different outcome than the initial panel decision.
-
Significance of the Case: The decision to grant an en banc rehearing underscores the profound constitutional questions at stake and the significant impact the ruling could have on public policy and Second Amendment jurisprudence across the Ninth Circuit’s jurisdiction, which includes California and several other Western states.
The rehearing indicates that the constitutional issues surrounding ammunition background checks are highly contested and that the state of California believes there are strong arguments to uphold its laws. It also suggests that some judges on the Ninth Circuit may disagree with the panel’s application of the Bruen test or its interpretation of historical analogues.
Why Rhode v. Bonta Matters Beyond California
Even with the en banc rehearing, Rhode v. Bonta remains a pivotal case for the Second Amendment for several reasons:
-
Clarifying Bruen’s Reach: The case directly tests the scope and application of the Supreme Court’s Bruen decision. How the Ninth Circuit ultimately applies Bruen’s historical test to ammunition regulations will provide crucial guidance for other courts facing similar challenges nationwide.
-
Ammunition as a Protected Component: It reinforces the argument that ammunition is fundamentally linked to the right to bear arms. A victory for the plaintiffs, even if delayed, solidifies the principle that restrictions on ammunition are just as constitutionally suspect as restrictions on firearms themselves.
-
Blueprint for Future Challenges: Regardless of the final outcome, the legal arguments and judicial reasoning developed in Rhode v. Bonta will serve as a blueprint for future challenges to ammunition restrictions in other states that have similar laws, such as New York, New Jersey, and others.
-
Ongoing Battle for 2A Rights: This case is a stark reminder that the fight for Second Amendment rights is an ongoing, complex, and often protracted legal battle, with significant implications for individual liberties.
Conclusion
Rhode v. Bonta represents a critical chapter in the ongoing struggle over gun control and Second Amendment rights in California and across the nation. The initial 9th Circuit ruling in 2025, which struck down the state’s ammunition background check requirement, was a landmark victory for gun rights advocates, establishing a strong precedent that ammunition is constitutionally protected and subject to the Bruen historical test. While the en banc rehearing in 2026 introduces uncertainty, it also highlights the profound importance of the legal questions involved. The ultimate decision will undoubtedly shape the future of ammunition regulation and the interpretation of the Second Amendment for years to come, offering either a renewed victory for gun owners or a setback that will fuel further legal challenges.
