context
The Mexican Supreme Court of Justice of the Nation (SCJN) issued its final ruling on the constitutionality of the lithium nationalization law on Tuesday, March 24, 2026.
The decision was the result of a long-standing constitutional challenge (Acción de Inconstitucionalidad 78/2022) filed by a minority group of legislators against the 2022 reforms.
Key Details of the Ruling
Validation of State Monopoly: The Court upheld Articles 1, 5 BIS, and 10 of the Mining Law. This officially confirms that lithium is a "strategic mineral" and its exploration, exploitation, and processing are the exclusive right of the Mexican State.
Dismissal of Challenges: The Court rejected arguments that the law violated "legal certainty" for existing concession holders. It also ruled that a specific "indigenous consultation" was not required for this general change to the mining framework.
The "Constitutional Shield": A major factor in the 2026 decision was a further constitutional amendment passed on October 31, 2024, which explicitly added lithium to the list of "strategic areas" in the Mexican Constitution (Articles 25, 27, and 28). The Court ruled that because the Constitution now explicitly forbids lithium concessions, the 2022 law is fully aligned with the nation's highest law.
How This Affects the Cadence/Ganfeng Case
Ironically, while this ruling is a "win" for the Mexican government domestically, it serves as the "smoking gun" for the international arbitration at ICSID:
Proof of Permanent Expropriation: In international law, an expropriation is often hard to prove if the government says it is "temporary" or "under review." By having the Supreme Court declare the ban on private concessions final and constitutional, Mexico has provided the ICSID Tribunal with definitive proof that the investors' rights have been permanently extinguished.
Exhaustion of Local Remedies: One of Mexico's favorite defenses is to argue that investors should have fought in Mexican courts first. Now that the Mexican Supreme Court has ruled, Cadence and Ganfeng can prove there is no remaining legal path in Mexico, making the international arbitration the only venue left for justice.
The Shift to Damages: Since the legality of the act is now "settled" in Mexico, the ICSID case will focus almost entirely on the valuation of the loss. The question is no longer "Did Mexico take it?" but rather "How many hundreds of millions of dollars must Mexico pay for taking it?"
