Defendant appeals from a “decision and order” of the Civil Court of the City of New York, New York County (Sabrina B. Kraus, J.), entered November 25, 2019, after a nonjury trial, in favor of plaintiff and awarding her damages in the principal sum of $8,500. Per Curiam Appeal from “decision and order” (Sabrina B. Kraus, J.), entered November 25, 2019, deemed an appeal from the ensuing judgment (same court and Judge), entered December 17, 2019, and so considered (see CPLR 5520[c]), judgment reversed and a new trial ordered, without costs. Plaintiff commenced this action by summons with endorsed complaint for “breach of contract — services unrendered” on February 20, 2013, seeking to recover a $10,000 expert witness fee paid to defendant, an otolaryngologist. Although the evidence showed that the breach of contract claim was time-barred (see CPLR 213[2]), the trial court, in effect, conformed the pleadings to the proof, and awarded judgment to plaintiff based on unjust enrichment and quantum meruit. The court did so after determining that the parties’ oral contract included defendant’s obligation to testify at trial but the contract did not address the contingency encountered by the parties: that plaintiff’s prior action would be dismissed prior to trial such that defendant did not need to provide expert trial testimony. While trial and appellate courts have the power to conform pleadings to the proof even in the absence of a motion by the parties, provided there is no significant prejudice or surprise to the opposing party (see Matter of Allstate Ins. Co. v. Joseph, 35 AD3d 730, 731 [2006]; Cartwright Van Lines v. Barclays Bank of N.Y., 120 AD2d 478, 479 [1986], lv denied 68 NY2d 608 [1986]), it cannot be said that defendant was not prejudiced by the Court’s consideration of the new theories of liability in this case. In the circumstances, and given the potential merit of the quasi contract claims, and the prejudice to defendant in the prior adjudication of such claims without notice, we deem it appropriate to permit plaintiff to amend her complaint to add the new claims and to order a new trial (see Yantic Grain & Prods. Co. v. Bullet Hole Farms, 29 AD2d 764 [1968]). “There are many cases where a new trial should be granted because of complexity, confusion, the possibility of other proof, error, misconception on the part of the Trial Judge as to the burden of proof or for other appropriate reasons…Also certain cases peculiarly lend themselves to a reconsideration of the facts by a trial court. The selection of the method of disposition remains in the discretion of the appellate court” (Victor Catering Co. v. Nasca, 8 AD2d 5, 9 [1959]; see Weinstein Korn Miller, N.Y. Civil Practice CPLR §5522.05). We note that the trial court correctly concluded that the quasi-contract causes of action accrued upon the occurrence of the wrongful act giving rise to the duty to make restitution, which act occurred on March 15, 2007, and, therefore, the quasi-contract causes of action are not time-barred (see generally Kaufman v. Cohen, 307 AD2d 113, 127 [1st Dept 2003]). All concur THIS CONSTITUTES THE DECISION AND ORDER OF THE COURT Dated: January 22, 2021
