Marvin Roy Feldman Karpa v. United Mexican States
ICSID · Investment (ICSID and treaty) · Mexico · 16 Dec 2002
Why it matters
This is a landmark NAFTA investment arbitration case that clarified the scope of national treatment under Article 1102, particularly regarding de facto discrimination against foreign investors. It established that differential treatment based on nationality, even if not explicitly stated, can violate NAFTA. The case also addressed the burden of proof in showing 'like circumstances' and the limits of expropriation claims for regulatory measures.
Summary
Marvin Feldman, a US citizen, owned CEMSA, a Mexican company that exported cigarettes. Mexico imposed an excise tax (IEPS) on cigarettes but allowed rebates for exports. Initially, only producers could get rebates, excluding resellers like CEMSA. After a Mexican Supreme Court ruling in 1993, the law was changed to allow all exporters rebates, but CEMSA still faced obstacles because it could not provide invoices showing the tax separately (as it bought from retailers). From 1996-1997, CEMSA received rebates, but in December 1997, Mexico stopped paying and later amended the law to again exclude resellers. Feldman claimed this violated NAFTA Articles 1102 (national treatment), 1105 (fair and equitable treatment), and 1110 (expropriation). The Tribunal found no expropriation because the measures did not deprive Feldman of all economic use of his investment. However, it found a violation of national treatment: Mexico treated CEMSA less favorably than domestic cigarette producers in like circumstances, as the rebate denial was effectively based on nationality (since only foreign-owned resellers were affected). The Tribunal awarded damages for unpaid rebates from October-November 1997, totaling about 9.46 million Mexican pesos plus interest. The decision is significant for establishing that differential treatment of foreign investors can be proven by circumstantial evidence and that the 'like circumstances' test requires comparing investors in the same business sector.
