US Supreme Court: Judgment in Smith & Wesson Brands, Inc. et al. v. Estados Unidos Mexicanos (Mexico) – A few takeaways
Written by Mayela Celis, Maastricht University
In June 2025, the US Supreme Court delivered its opinion in Smith & Wesson Brands, Inc. et al. v. Estados Unidos Mexicanos (Mexico) 605 U.S. 280 (2025). The Opinion is available here. We have previously reported on this case here, here and here (on the hearing).
As previously indicated, this is a much-politicized case brought by Mexico against US gun manufacturers, alleging inter alia negligence, public nuisance and defective condition. The basic theory laid out was that defendants failed to exercise reasonable care to prevent the trafficking of guns to Mexico causing harm and grievances to this country. In this regard, the complaint focuses on aiding and abetting of gun manufacturers (rather than of independent commission).
In a brilliant judgment written by Justice Kagan, the Court ruled that PLCAA bars the lawsuit filed by Mexico. Accordingly, PLCAAS’s predicate exception did not apply to this case. Read more
French Supreme Court upholds asymmetric jurisdiction clauses in Lastre follow-up
by Jean-Charles Jais, Guillaume Croisant, Canelle Etchegorry, and Alexia Kaztaridou (all Linklaters)
On 17 September 2025, the French Cour de cassation handed down its decision on the Lastre case. This followed a landmark preliminary ruling of February 2025 from the CJEU, which laid out the conditions for a valid asymmetric jurisdiction clause under article 25 of the Brussels I recast regulation.
Asymmetric jurisdiction clauses allow one party to initiate proceedings in multiple courts or any competent court, while the other party has fewer options or is restricted to a specific jurisdiction. Such clauses are common in financial agreements (read more in our previous blog post here).
In the latest development of the Lastre case in France, the French Supreme Court opted for a pro-contractual autonomy stance, favouring the validity of asymmetric jurisdiction clauses.
Using Foreign Choice-of-Law Clauses to Avoid U.S. Law
Can private actors utilize choice-of-law clauses selecting the laws of a foreign country to avoid laws enacted by the United States? In this post, I argue that the answer is a qualified yes. I first examine situations where the U.S. laws in question are not mandatory. I then consider scenarios where these laws are mandatory. Finally, the post looks at whether private parties may rely on foreign forum selection clauses and foreign choice-of-law clauses—operating in tandem—to avoid U.S. law altogether.
