Where in a dispute between an employer and a union over changes to a pension-contribution program the district court vacated an arbitration award in favor of the union, the arbitrator lacked the authority to decide the issue of the formation of the contract, so the court did not err in vacating the award, but the court erred in granting summary judgment to the employer and rescinding the provision that outlined the program since the employer’s mistake in failing to notice that the final draft of the agreement omitted a cap on hours was due to its own inattention in arm’s length negotiations between sophisticated parties.
Judgment is affirmed in part; reversed in part; remanded.
