Facts

On April 14, 2011, a sole arbitrator sitting in London rendered an arbitral award in a contractual dispute between B. and C., as claimants, and a third company and A., as defendants. The award declared that A. was a party to the disputed contract and ordered the defendants to pay the claimants the sum of $5,000,000, reimburse their legal fees and costs amounting to $136,195, and pay interest.

The Federal Tribunal considered that a foreign "non-Lugano" judgment constitutes a title for definitive release of attachment within the meaning of Art. 271(1)(6) of the DEBA. It also ruled that it was not arbitrary to hold that the attachment judge can rule incidentally on the enforceability of the "non-Lugano" foreign decision, following a summary…
