The decision is important because it provides guidance on the disclosures that parties should expect from an arbitrator when circumstances exist which might give rise to justifiable doubts as to his or her impartiality. In providing this guidance, the Supreme Court discussed the interaction between an arbitrator’s duties of impartiality, disclosure, and confidentiality, which are not easily reconciled.
