Wintershall Aktiengesellschaft v. Argentine Republic
ICSID · Investment (ICSID and treaty) · Argentina · 8 Dec 2008
Why it matters
This award is a landmark decision on the scope of most-favoured-nation (MFN) clauses in bilateral investment treaties. The tribunal held that an MFN clause does not automatically extend to dispute resolution provisions unless the contracting parties clearly intended it. It distinguished between substantive treatment and procedural/jurisdictional requirements, reinforcing that investors must comply with pre-arbitration conditions like local litigation periods. The decision contributed to the ongoing debate on whether MFN clauses can import more favorable arbitration provisions from other treaties.
Summary
Wintershall, a German company, invested in Argentina through a local subsidiary in the oil and gas sector. Following Argentina's economic crisis and regulatory changes, Wintershall claimed that Argentina violated the Argentina-Germany BIT by imposing export restrictions and other measures that harmed its investment. Instead of first submitting the dispute to Argentine courts for 18 months as required by Article 10(2) of the BIT, Wintershall directly initiated ICSID arbitration. Argentina objected to jurisdiction, arguing that Wintershall had failed to comply with the mandatory precondition of litigating in local courts. Wintershall countered that the MFN clause in Article 3 of the BIT allowed it to invoke the more favorable dispute resolution provisions of the Argentina-US BIT, which permitted direct access to arbitration without prior local litigation. The tribunal, after a detailed analysis of treaty interpretation principles and the ejusdem generis rule, rejected Wintershall's argument. It found that Article 10(2) was a jurisdictional requirement, not merely procedural, and that the MFN clause did not extend to dispute resolution because the contracting parties did not intend it to cover such matters. The tribunal emphasized that MFN clauses apply only to the same subject matter (ejusdem generis) and that dispute resolution is a distinct category. It also noted that ICSID awards have no binding precedential effect. Consequently, the tribunal upheld Argentina's objection and declined jurisdiction. The decision is significant for its strict interpretation of MFN clauses and its clarification that pre-arbitration requirements like local litigation periods are jurisdictional conditions that cannot be bypassed via MFN clauses unless the treaty explicitly allows it.
The detail
Parties: Wintershall Aktiengesellschaft v. Argentine Republic

Outcome: The Tribunal upheld Argentina's first preliminary objection to jurisdiction, finding that Wintershall had not complied with Article 10(2) of the Argentina-Germany BIT (requiring submission to local courts for 18 months) and that the MFN clause in Article 3 did not allow it to bypass that requirement. The dispute was held not within ICSID jurisdiction.
Applicable law: Argentina-Germany Bilateral Investment Treaty (BIT), ICSID Convention, ICSID Arbitration Rules
Issues in play: The case involved the interpretation of the MFN clause in Article 3 of the Argentina-Germany BIT and whether it could extend to the dispute resolution clause (Article 10) to allow direct access to ICSID arbitration without first litigating in local courts for 18 months.
