Background and Key Players

In 2021, the Mexican government, led by then-Secretary of Foreign Affairs Marcelo Ebrard, initiated a lawsuit against eight U.S. firearm manufacturers. The aim was to hold these companies accountable for the illegal use of their products in Mexico, which has been grappling with a severe gun trafficking issue.

Ebrard presented the lawsuit as a “bold and innovative act,” but critics argued it was more of a political maneuver than a genuine attempt to address the problem. The case was based on the Protection of Lawful Commerce in Arms Act (PLCAA), a U.S. law enacted in 2005 that shields firearm manufacturers from liability when their products are used illegally.

The Legal Battle and Supreme Court Decision

A federal judge dismissed the case in October 2022, stating that the lawsuit lacked legal standing. The Supreme Court unanimously upheld this decision, refusing to review the case’s merits. The judge emphasized that although he sympathized with Mexico’s struggle against illegal gun trafficking, he was obligated to apply the law.

The Gun Trafficking Problem in Mexico

According to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) in the U.S., about 74% of traced firearms in Mexico originate from the U.S., primarily from Texas, Arizona, and California. Each year, around 200,000 firearms illegally enter Mexico from the U.S., with Mexican authorities recovering only about 20,000 of them annually.

Since the start of Mexico’s “war on drugs” in December 2006, approximately 464,000 intentional homicides have occurred in Mexico, with 73% of these crimes involving firearms. The gravity of the issue is undeniable, despite recent reports of decreased homicides under President Claudia Sheinbaum’s administration.

Financial and Practical Implications of the Lawsuit

The legal battle against U.S. gun manufacturers incurred substantial costs in legal fees, court expenses, translations, travel expenses, and diplomatic personnel. These resources could have been allocated to strengthening border controls, enhancing intelligence efforts, or improving internal gun control measures.

Instead of investing in practical solutions, the Mexican government opted for a symbolic legal campaign, designed to garner public support rather than achieve success in court.
