The Supreme Court of the United States rejects Sacyr's appeal against the Panama Canal arbitration. The judges validate the ruling of the arbitration court that condemned the GUPC consortium to pay 272 million dollars to the Canal Authority.

GUPC's challenge to the arbitrators was based on their alleged bias as a result of professional interactions between them or between them and persons representing the ACP. “We refuse to grant an annulment simply because these people worked together elsewhere. The record does not reveal any evidence of actual bias in the Panama 1 Arbitration," said the ruling.
