3. On January 20, 2009, the Tribunal and the Parties held a first session in Paris, France. On April 17, 2009, the Tribunal held a hearing on provisional measures in Washington D.C. On January 22, 2010, the Tribunal held a hearing on jurisdiction in Paris, issuing its Decision on Jurisdiction on June 2, 2010. A dissenting opinion by Professor Orrego Vicuña was attached to the Decision on Jurisdiction. The Tribunal then held a hearing on liability in Paris from March 8 through 11, 2011, issuing a Decision on Liability on December 14, 2012. A dissenting opinion by Professor Orrego Vicuña was attached to the Decision on Liability. 

4. On July 8, 2013, Dechert (Paris) LLP (“Dechert”), counsel representing Ecuador, sent an unsigned letter (the “July 8 letter”) to Professor Orrego Vicuña regarding news reports stating that he had been appointed as arbitrator multiple times (“repeat appointments”) by Freshfields.

Ecuador also asked for disclosure of the compensation paid in these proceedings.
