International Centre for Settlement of Investment Disputes (ICSID) Tribunal published its decision confirming that the Government of Mexico violated international law through its arbitrary and unfair treatment of Vulcan Materials Company ("Vulcan" or the "Company") and its investments in Quintana Roo. The decision directly contradicts Mexico's attempts to portray its actions as legitimate environmental enforcement. The Tribunal 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.
