Birmingham, Ala. – September 15, 2026 -- The International Centre for Settlement of Investment Disputes (ICSID) Tribunal has published a decision confirming that the Government of Mexico violated international law through its treatment of Vulcan Materials Company and its investments in Quintana Roo, contradicting Mexico's claims that its actions constituted legitimate environmental enforcement.
Tribunal rejects Mexico's environmental counterclaims as inadmissible
The ICSID panel declared Mexico's counterclaims of environmental harm inadmissible and found that Mexican environmental authorities improperly used regulatory powers to target Vulcan, shut down its lawful operations, and prevent the company from meaningfully defending itself in Mexican proceedings.
