Abe Fortas,
Commonwealth Coatings Corp. v. Continental Casualty Company…
“ It uses this singularly inappropriate case to announce a per se rule that in my judgment has no basis in the applicable statute or jurisprudential principles: that, regardless of the agreement between the parties, if an arbitrator has any prior business relationship with one of the parties of which he fails to inform the other party, however innocently, the arbitration award is always subject to being set aside. This is so even where the award is unanimous; where there is no suggestion that the nondisclosure indicates partiality or bias ”
