“… it seems to me that an expert arbitrator should not in effect give evidence to himself without disclosing the evidence on which he relies to the parties, or if only one to that party. He should not act on his private opinion without disclosing it. It is undoubtedly true that an expert arbitrator can use his own expert knowledge. But a distinction is made in the cases between general expert knowledge and knowledge of special facts relevant to the particular case.”
“My experience … confirms … [in effect that the Winnersh units are comparable].”
