in its so-called “arrêt Garnier” dated 14 February 2024, the French Cour de Cassation upheld the Paris Court of Appeal’s decision to reject a claim for damages against an arbitrator who had belatedly rendered an award thereby leading to its annulment.

In a nutshell: the claimant prevailed in domestic arbitration proceedings and the respondent was ordered to pay a certain amount of damages to the claimant. Since, however, the award was issued belatedly, the respondent prevailed in set aside proceedings before the French courts and the latter ruled upon the merits of the dispute. At this juncture, however, the claimant only obtained a much lower sum of damages than that which it had obtained in the arbitration proceedings.

The aggrieved claimant then sued the arbitrator and its insurer, claiming damages amounting to, at least, the difference between those obtained in the arbitration and those obtained before the national court, framing this head of losses as a loss of opportunity (perte de chance). Its request was, however, rejected both on appeals and by the French supreme court. Both courts decided that, even though the arbitrator committed a contractual breach by issuing the award late, the claim could not prevail because there was no compensable loss nor a causal link between the breach and the alleged loss.

This was because the concept of loss of opportunity only allows a claim for a fraction of the damages suffered, whereas in this case the claimant was in reality seeking full compensation. And, in any event, because the reduction in damages resulted not from the arbitrators’ fault, but from the decision of the national court before which the claimant was able to assert its rights.

Overall, this decision provides interesting teachings for all arbitration practitioners and parties which have recourse to it, as it sheds further light on the conditions under which arbitrators can be held liable, and the monetary exposure (if any) which they face when failing to discharge their duties in accordance with their contractual mandate.
