In a negligence action to recover damages for personal injury, the defendants appeal from a judgment of the Supreme Court, Queens County, entered December 10, 1963 after trial, upon a jury's verdict of $25,000 in favor of the plaintiff. Judgment reversed on the law and the facts, and a new trial granted, with costs to abide the event. We find that the gravamen of the complaint, as particularized by the bill of particulars, was common-law negligence and not a violation of section 167 Lab. of the Labor Law. In view of the pleadings and the proof, the injection of that statute into the case by plaintiff, after he had rested, constituted surprise to the defendants. Under the circumstances, the denial of defendants' application to reopen their case for the purpose of presenting evidence as to the nonapplicability of said statute (Labor Law, § 167) constituted an improvident exercise of discretion. In our opinion a new trial is required in the interests of justice. Beldock, P.J., Ughetta, Christ, Hill and Rabin, JJ., concur.
