On 27 October 2017, the Swiss Federal Supreme Court (the "Court") published on its website a new decision in the field of international arbitration (the "Decision").1 The Decision was rendered by all five members of the First Civil Chamber and, in addition, it will be included in Court's publication of leading cases, thereby adding particular weight to this case.

In the Decision, the Court summarizes the requirements to validly waive the right to challenge an award with the Court and addresses the question whether a party can despite such a waiver still request a revision.

On 1 February 2017, Croatia filed an action for annulment with the Court and, subsidiary, a request for a revision3 of the award. Croatia alleged, inter alia, that its arbitrator, law professor Jakaa Barbić, should have recused himself as arbitrator given that he had been designated by INA as arbitrator in another arbitration around 3 October 2013, at a time when INA was already under the control of MOL. These circumstances should have been disclosed to the parties as they would raise justifiable doubts as to the independence and impartiality of the Croatian law professor.
