Why it matters
Tecmed v. Mexico is a landmark investment treaty case that established the 'sole effects' doctrine for indirect expropriation, focusing on the impact of the measure on the investment rather than the intent of the state. It also set a high standard for fair and equitable treatment, requiring stability and predictability in the regulatory framework. The award is frequently cited in subsequent investment disputes.
Summary
Tecmed, a Spanish company, invested in a hazardous waste landfill in Hermosillo, Mexico, through its Mexican subsidiary Cytrar. The landfill had an operating permit that was initially indefinite but later changed to annual renewals. After a change in local government and community opposition, the Mexican environmental authority (INE) denied renewal of the permit in November 1998, effectively forcing the landfill to close. Tecmed claimed this amounted to expropriation without compensation and violated the fair and equitable treatment standard under the Spain-Mexico BIT. The Tribunal, applying the BIT and international law, held that the denial of the permit was an indirect expropriation because it deprived Tecmed of the value of its investment. It also found a breach of fair and equitable treatment because the regulatory framework was not stable and predictable, and the investor's legitimate expectations were frustrated. The Tribunal awarded compensation based on the market value of the investment as of the date of expropriation, plus compound interest. The case is notable for its articulation of the 'sole effects' test for expropriation and its emphasis on the investor's legitimate expectations in fair and equitable treatment analysis.
