The Second Department explained the criteria for vacation of an arbitration award:
A party seeking to overturn an arbitration award on one or more grounds stated in CPLR 7511(b)(1) bears a “heavy burden” … , and must establish a ground for vacatur by clear and convincing evidence … . An arbitration award must be vacated if a party’s rights were impaired by an arbitrator who “exceeded his [or her] power or so imperfectly executed it that a final and definite award upon the subject matter submitted was not made” (CPLR 7511[b][1][iii]). An arbitrator exceeds his or her power where the “award violates a strong public policy, is irrational or clearly exceeds a specifically enumerated limitation on the arbitrator’s power” … . An award will be vacated as indefinite only if it leaves the parties unable to determine their rights and obligations, if it does not resolve the controversy submitted, or if it creates a new controversy … .
