REVIEW OF THE DECISION ON JURISDICTION OF THE METHANEX TRIBUNAL, AUGUST 5, 2002

On August 5, 2002, a NAFTA Chapter 11 tribunal issued an interim ruling in the Methanex vs. United States case, determining that it lacked jurisdiction over the original claims because there was no "legally significant connection" between California's MTBE ban and Methanex, which only supplied a component (methanol) for the regulated product. The tribunal rejected the notion that indirect economic impacts are sufficient to establish jurisdiction under Article 1101. However, it left open a narrow path for jurisdiction if Methanex can prove a specific "intent" to discriminate against the company in favor of a domestic competitor. The author notes that while the ruling does not exempt public welfare measures from challenge, it limits the range of potential claimants by excluding those only indirectly affected.

• The Tribunal ruled that it lacked jurisdiction over Methanex's original claims because the measures adopted by California to ban MTBE did not have a "legally significant connection" to the investor or investment.
• The Tribunal rejected the argument that any government measure causing an indirect economic impact is "related to" an investor under Article 1101 of NAFTA, stating that accepting such a broad scope would allow Chapter 11 to address every type of indirect economic impact.
• Jurisdiction may still be established if Methanex can provide evidence that the measures were specifically intended to discriminate against the company in favor of a domestic ethanol producer, such as Archer-Daniels-Midland.
• The ruling confirms that environmental, human health, and social welfare measures of general application remain subject to challenge under Chapter 11, provided there is a legally significant connection to the investor.
• The Tribunal explicitly expressed satisfaction that the legal arguments and submissions of the parties had become available in the public domain via various websites, which the author suggests supports greater transparency in future investment litigation.
• The Tribunal did not rule on the substantive merits of the case, such as whether market share constitutes an expropriable asset or the specific interpretations of Articles 1102, 1105, or 1110.
