Correction, 9/11/2013: An earlier version of this article incorrectly referred to a "second-place tie" between Shearman & Sterling and Curtis Mallet-Prevost, Colt & Mosle, for most entries in the 2013 Arbitration Scorecard. Due to a data processing error, we failed to give Shearman credit for one entry in the survey. In our corrected rankings, Shearman is in second place with 35 arbitrations and Curtis Mallet-Prevost is in third with 34 arbitrations. We regret the error.

Ten years ago—ignoring the prominent "PRIVATE, KEEP OUT" sign—we cracked open the door that led to the hidden world of arbitration. In the summer 2003 issue of Focus Europe, we gave unsanitized accounts of 40 large international arbitrations. At an International Bar Association panel the next year, the secretary-general of the ICC Court of International Arbitration criticized our endeavor to publicly track this private-sector, traditionally secret system of justice. But with every biennial survey, the door kept opening wider.
