On review of submissions pursuant to rule 500.2 (b) of the Rules of the Court of Appeals (22 N.Y.CRR 500.2 [b]), order reversed, with costs, the petition to stay arbitration granted and the cross petition to compel arbitration dismissed. Our reading of the collective bargaining agreement as a whole establishes the parties' plain and unambiguous intent to limit the right to demand step 3 grievance arbitration to the college and the union. Accordingly, respondent faculty member's arbitration demand was without legal effect (cf. Matter of Horseheads Cent. School Dist. [ Horsehead Teachers' Assn.], 55 N.Y.2d 949).
Concur: Chief Judge COOKE and Judges JASEN, GABRIELLI, JONES, WACHTLER, FUCHSBERG and MEYER.
