627. A party may ask for an arbitrator’s recusation by notifying a document stating its reasons to the other party, to the arbitrator concerned and, if applicable, to the other arbitrators, within 15 days after becoming aware of the appointment or appointments or of the cause for recusation.
A party may only ask for the recusation of an arbitrator it appointed for a cause which arose or was discovered after the appointment was made.
The arbitrator or arbitrators are required to rule on the recusation request without delay, unless the arbitrator concerned withdraws or, the other party supporting the request, is compelled to withdraw.
If the recusation cannot be so obtained, a party may, within 30 days after being advised of it, ask the court to rule on the recusation. The arbitrator concerned and, if there are more than one, the other arbitrators, may nonetheless continue the arbitration proceedings and make an award for so long as the court has not made its ruling.
