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

This briefing analyzes an August 5, 2002, interim ruling by a NAFTA Chapter 11 Tribunal in the case of Methanex vs. the United States of America. The Tribunal ruled that it lacked jurisdiction over Methanex's original claims because the California environmental measures banning MTBE did not have a "legally significant connection" to Methanex, which supplied a component (methanol) rather than the regulated product (MTBE). The Tribunal left open a narrow path for jurisdiction if Methanex can prove a specific discriminatory intent to harm the company, giving the claimant 90 days to provide evidence for this argument.

• The Tribunal ruled that it lacked jurisdiction over Methanex's initial claims because there was no "legally significant connection" between the investor and the California measures banning MTBE. The ruling established that since Methanex supplied a component (methanol) for MTBE rather than producing MTBE itself, the connection was too indirect to grant jurisdiction under Article 1101 of NAFTA.
• The Tribunal rejected two extreme interpretations of Article 1101: it declined to use a restrictive test requiring a measure to be "primarily aimed at" a foreign investor, but it also rejected the claim that any measure affecting an investor is automatically "related to" that investor.
• Jurisdiction may still be established if Methanex can prove the "intent issue"—specifically, that the measures were intended to discriminate against Methanex to favor a domestic competitor, Archer-Daniels-Midland (AD), due to campaign contributions to California Governor Gary Davis.
• The ruling confirms that environmental, human health, and social welfare measures of general application can be challenged under NAFTA Chapter 11, provided there is a legally significant connection to the investor. While it reduces the number of potential claimants by excluding those with only incidental economic impacts, it does not limit the types of public welfare measures subject to challenge.
• The Tribunal did not rule on the substantive merits of the case, including interpretations of Article 1102 (national treatment), Article 1105 (minimum international standards), or Article 1110 (expropriation). Specifically, it did not address US arguments regarding whether market share constitutes an expropriable asset.
• The Tribunal expressed support for transparency in trade and investment litigation by noting its satisfaction that the case's extensive legal submissions had become available in the public domain via various websites.
