However, there is no default procedure specifically for multi-party arbitrations. 4.3 Court Intervention The court intervenes in the selection of arbitrators and may act as the appointing authority at the request of a party in the following circumstances: • if a party fails or refuses to appoint an arbitrator, the parties fail to agree on the sole arbitrator or the two designated arbitrators fail to agree on the third arbitrator; and • where the arbitration institution fails or is unable to perform its duty as an appointing authority within a reasonable time, upon receiving a request for appointment. In an ad hoc arbitration, the court may intervene in the following circumstances. • The parties failed to provide a method for appoint - ing or replacing an arbitrator or substitute arbitra - tor, or the method agreed upon is ineffective. • The national president of the IBP fails or refuses to act within: (a) such period as may be allowed under the perti - nent rules of the IBP; (b) such period as may be agreed upon by the parties; or (c) 30 days from receiving such request for appointment. 4.4 Challenge and Removal of Arbitrators An arbitrator may be challenged on any of the grounds provided for in the ADR Act and its IRR, Republic Act No 876 or the UNCITRAL Model Law.

Arbitrators must disclose any circumstances likely to give rise to justifiable doubts as to their impartiality or independence. From the time of their appointment and throughout the arbitration proceedings, an arbi - trator must disclose any such circumstances to the parties without delay unless they have already been informed of these circumstances by the arbitrator. An arbitral tribunal has the first opportunity or compe - tence to rule on whether it has jurisdiction to decide a dispute submitted to it, including any objections that a party may have concerning: • the existence or validity of the arbitration agree - ment; or • the fulfilment of any condition precedent before filing a request for arbitration.
