    Robert W. Newton et al., Appellants, v Peter D. Booras et al., Respondents.
   — In an arbitration proceeding, petitioners appeal from an order of the Supreme Court, Orange County, dated November 10, 1980, which denied their motion to disqualify respondents’ arbitrator on the ground of bias. Order affirmed, with $50 costs and disbursements. Petitioners had knowledge of the arbitrator’s alleged bias and their failure to initially object constituted a waiver. Mollen, P.J., Cohalan, Margett and O’Connor, JJ., concur.
