California’s “One-Gun-a-Month” Law Struck Down: What This Means for Gun Owners

California has long been known for having some of the nation’s strictest gun laws, but a recent federal court decision has dealt a significant blow to one of the state’s key firearm regulations. The Ninth Circuit Court of Appeals recently affirmed a lower court’s decision striking down California’s “one-gun-a-month” law, ruling that it violates the Second Amendment to the U.S. Constitution. This landmark decision has far-reaching implications for gun owners throughout California and sets an important precedent for future Second Amendment challenges.

Understanding California’s One-Gun-a-Month Law

California’s contested law prohibited most individuals from purchasing more than one firearm within any 30-day period. The regulation was designed as a public safety measure, with lawmakers arguing it would help reduce gun trafficking and limit the rapid accumulation of firearms by potentially dangerous individuals. However, this restriction placed significant limitations on citizens’ ability to exercise their Second Amendment rights.

The law contained certain exceptions, but for the vast majority of Californians, purchasing multiple firearms within a month was prohibited regardless of their background, training, or legitimate need for additional weapons. This blanket restriction applied to all types of firearms covered under the law’s definition.

The court’s decision was heavily influenced by the Supreme Court’s landmark ruling in N.Y. State Rifle & Pistol Ass’n v. Bruen, decided in 2022. The Bruen decision fundamentally changed how courts must analyze Second Amendment challenges, establishing a new framework that has proven more protective of gun rights.

Under the Bruen standard, courts evaluating Second Amendment challenges must follow a two-step analysis:

Step One: Plain Text Coverage Courts must first determine whether the Second Amendment’s “plain text” covers the regulated conduct. If the challenged law regulates conduct that falls within the scope of the Second Amendment’s protections, the Constitution creates a presumption that such conduct is protected.

Step Two: Historical Tradition If the conduct is covered by the Second Amendment’s plain text, the law can only be upheld if the government can demonstrate that the regulation is consistent with the nation’s “historical tradition of firearm regulation.” This requires showing historical precedent from before, during, and after the founding era that supports comparable restrictions.

This framework represents a significant departure from previous approaches that allowed courts to balance Second Amendment rights against government interests using intermediate scrutiny. The Bruen standard places a much heavier burden on the government to justify firearm restrictions through historical precedent rather than policy arguments.

Real World Example: Nguyen v. Bonta

In this case, individual plaintiffs who desired to purchase more than one firearm per month challenged California’s restriction in federal court. The plaintiffs argued that the one-gun-a-month law facially violated the Second Amendment – meaning that no set of circumstances existed under which the law could be constitutionally applied.

The federal district court agreed with the plaintiffs and granted summary judgment in their favor, finding that California’s law violated the Second Amendment under the Bruen framework. California appealed this decision to the Ninth Circuit Court of Appeals, hoping to reverse the lower court’s ruling.

The Ninth Circuit’s Analysis

The Ninth Circuit applied the Bruen framework and reached several key conclusions:

Plain Text Coverage: The court determined that purchasing multiple firearms within a 30-day period fell within the Second Amendment’s protection because the right to acquire arms is an “ancillary right necessary to the core right” to keep and bear arms. Without the ability to acquire firearms, the core Second Amendment right would be meaningless.

Meaningful Constraint: The court found that California’s 30-day restriction constituted a “meaningful constraint” on Second Amendment rights, not merely a minor inconvenience or administrative requirement.

Historical Analysis: Most importantly, the Ninth Circuit concluded that California failed to demonstrate a historical tradition supporting such broad purchase restrictions. While the state pointed to some historical examples of regulations targeting specific groups or requiring dealer registration and sales tax tracking, these precedents were found insufficient.

The court noted that early American laws did restrict certain “dangerous” individuals from possessing firearms, but these were targeted restrictions based on individual circumstances, not blanket prohibitions on all citizens. California’s cited examples of dealer regulations were also distinguished because they primarily burdened dealers rather than purchasers and were much more limited in scope.

Implications for Gun Owners and California Law

California can no longer enforce its one-gun-a-month restriction, allowing law-abiding citizens to purchase multiple firearms within a 30-day period, subject to all other applicable regulations and background check requirements.

The decision strengthens Second Amendment protections in the Ninth Circuit, which covers California and several other western states. It demonstrates courts’ willingness to strictly apply the Bruen standard to strike down gun regulations lacking historical support.

Other Considerations for Gun Owners

While this decision removes one restriction, California gun owners must still comply with numerous other state and federal requirements, including:

  • Universal background checks
  • Waiting periods
  • Assault weapon restrictions
  • High-capacity magazine bans
  • Safe storage requirements
  • Various licensing and registration obligations

Gun owners should remain informed about applicable laws and ensure full compliance with all remaining regulations.
