The author recalls that the international arbitration community sat up and took notice when a recent decision issued by Judge Alvin K. Hellerstein from the Southern District of New York in the Pemex case ordered that an arbitration award that had been set aside by the Mexican courts could be enforced in the United States. The case was particularly noteworthy because there is only one other reported case in the United States— Chromalloy from 1996—which ordered the same result, albeit for different legal reasons. While the court in Pemex did not rely on the specific reasoning in Chromalloy, it did remark that Chromalloy remains alive. The author concludes that this case will unlikely open the floodgates in the United States to enforcement of awards that have been set aside abroad. The facts in this case distinguish it from many of its predecessors. Nevertheless, it would be difficult to fathom how the court could or should have reached a different result under these circumstances. And it also gives a nod to a case that many thought had been dismissed as an outlier, and reminds us that parties remain captive to the courts at the seat of arbitration when it comes to nullification of international arbitration awards.
