(a) When a person is approached in connection with his possible appointment as an arbitrator, he shall disclose any circumstances likely to give rise, in the eyes of the parties, to justifiable doubts as to his impartiality or independence.
(b) An arbitrator, from the time of his 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.
(c) An arbitrator who has made a disclosure considers himself or herself to be impartial and independent of the parties despite the disclosed facts and therefore capable of performing his or her duties as arbitrator. Therefore, disclosure does not, in and of itself, demonstrate grounds sufficient to disqualify the arbitrator.
(d) Non-disclosure by an arbitrator of certain facts or circumstances alone does not constitute a ground for challenge. Only the facts or circumstances that he did not disclose can do so.
