Legal Action
The company has defied legal resolutions against its operation by arranging economically with the Mexican ecological authority, the Secretariat of the Environment and Natural Resources (Secretaría de Medio Ambiente y Recursos Naturales, Semarnat), pushing them to disregard ecological research done by some independent institutions and to instead accept most other independent as well as company-funded and government required studies. Continuous internal and external monitoring of mining activities has not produced any evidence of contamination to date.
On 5 February 2007, Pro San Luis Ecológico, A.C., filed a submission before the Commission for Environmental Cooperation under Article 14(1) of the North American Agreement on Environmental Cooperation. The submitter asserted that Mexico was failing to effectively enforce its environmental laws with respect to the authorization of the Cerro de San Pedro project in San San Luis Potos. In submission SEM-07-001 (Minera San Xavier)[link removed], the submitter asserted that in April 2006 Semarnat violated a Mexican court ruling by authorizing Minera San Xavier project for a second time. On 15 July 2009, the CEC Secretariat decided not to recommend the development of a factual investigation.
