There is an inter-State arbitration pending between Ecuador and the United States under the Bilateral Investment Treaty (BIT) between those two countries (Treaty between United States of America and the Republic of Ecuador Concerning the Encouragement and Reciprocal Protection of Investment, 27 August 1993). The Ecuador v. US case , which was initiated in June 2011, is, as far as I am aware, a very very rare instance of inter-State arbitral proceedings under a BIT. As is well known, one of the main purposes of BITs is to give investors the right to bring claims against the host state of investment. This feature of BITs, and the vast number of such treaties, has meant that investor-State arbitrations under BITs have replaced diplomatic protection as the primary means of settling investment disputes. There have been hundreds of investor-State proceedings before arbitral tribunals. However, BITs also contain compromissory clauses by which disputes concerning the interpretation or application of disputes under these treaties can be brought before arbitral tribunals established under the BIT. The only other inter-State BIT cases that I am aware of are the recent Italy and Cuba cases which were discussed in the April 2012 issue of the American Journal of International Law. In general, States leave it to the investor to protect its rights under the BIT.
The present proceedings brought by Ecuador are particularly interesting for a couple of reasons: one specific to investment law, the other relating to general international law. First of all, as the case arises out of Ecuador’s dissatisfaction with the interpretation given by an earlier investor-State arbitral tribunal (Chevron and Texaco Petroleum Company v. Republic of Ecuador, Partial Award, 30 March 2010) to a particular provision of the Ecuador – US BIT, the case may be construed as a way by which Ecuador is trying to use the inter-State procedure as a way of appealing the results of a case brought under the investor-State procedure. There have been concerns by many that there is no appellate procedure in the investment treaty system and this case seems to be an attempt to create one.
Secondly, Ecuador’s case raises a general question about how one interprets the standard compromissory clause to be found in treaties where jurisdiction is granted to an international tribunal over disputes between the parties “concerning the interpretation or application of the treaty”. Ecuador is of the view that the US has a different interpretation from it of a provision of the BIT. However, Ecuador does not argue that the US has violated the BIT, it only seeks to resolve a question about how the BIT should be interpreted. So, does the tribunal have jurisdiction over a case where the parties disagree about how a treaty should be interpreted but where there is no allegation that the respondent party has actually misapplied the treaty or done any act which constitutes a violation of the treaty. The question is whether this standard formulation of a compromisory clause means that international tribunals can only deal with concrete disputes about violations of treaties or whether they can play a general advisory function with respect to the meaning of the treaty. In short, what is a dispute about “interpretation”of a treaty? Read the rest of this entry…
