Grounds for Challenge

COL412014 CH. 42A GUAM INTERNATIONAL ARBITRATION

(a)When a person is approached in connection with his or her possible appointment as an arbitrator, he or she shall disclose any circumstances reasonably likely to give rise to material justifiable doubts as to his or her impartiality or independence. An arbitrator, from the time of his or her appointment and throughout the arbitral proceedings, shall without delay disclose any such circumstances to the parties unless they have already been informed of them by him or her.

(b)An arbitrator may be challenged only if circumstances exist that give rise to material justifiable doubts as to his or her impartiality or independence, or if he or she does not possess qualifications agreed to by the parties. A party may challenge an arbitrator appointed by him or her, or in whose appointment he or she has participated, only for reasons of which he or she becomes aware after the appointment has been made.
