    In the Matter of the Arbitration between Safeco Insurance Company, Respondent, and Commercial Union Assurance Companies, Appellant.
   In a proceeding pursuant to CPLR 7511 to vacate an arbitration award, the appeal is from a judgment of the Supreme Court, Nassau County (Becker, J.), dated January 10, 1983, which granted the application. 11 Judgment affirmed, with costs. 11 The arbitration award was properly vacated since there was no rational basis for it on this record (see Dahn v Lucks, 92 AD2d 537; Matter of Shand [Aetna Ins. Co.], 74 AD2d 442). Lazer, J. P., Mangano, Gibbons and Niehoff, JJ., concur.
