1A, 365 Mass. 731 [1974]), the plaintiff also moved for a new trial and for judgments against the companies notwithstanding the verdict. The judge denied these motions, and the plaintiff subsequently appealed to the Appeals Court. The defendant companies cross-appealed from the judge’s order that negative answers be substituted for the special verdicts returned by the jury on the estoppel and contributory negligence questions. The Appeals Court ordered the special verdict in response to jury question 1 to be set aside, ordered the entry of judgment against the defendant companies, and dismissed the plaintiff’s appeal from the order denying its motion for a new trial. New England Acceptance Corp. v. American Mfrs. Mut. Ins. Co., 4 Mass. App. Ct. 172 (1976). We granted the defendant companies’ application for further appellate review.
Massachusetts Rule of Civil Procedure 50 (b) is patterned after the Federal Rule of Civil Procedure 50 (b) on judgments notwithstanding the verdict. J.W. Smith & H.B. Zobel, Rules Practice § 50.19 (1977). While we have the power under this rule to order the entry of judgment n.o.v. and need not remand for a new trial,

United States, 112 F.2d 488, 492 (1st Cir.), cert, denied,
311 U.S. 697 (1940), we do so cautiously; Our great respect for the jury’s contribution of common sense and a sense of fairness to the judicial process requires us to view circumspectly any encroachment of the jury’s function. Furthermore, particular care must be exercised where, as in the case at bar, a judgment notwithstanding the verdict is to be granted in favor of the party having the burden of proof. See
Posttape Assoc. v. Eastman Kodak Co., 68 F.R.D. 323, 331 (E.D. Pa. 1975), rev’d on other grounds, 537 F.2d 751 (3d Cir. 1976). Cf.

An auditor initially heard this case prior to July 1,1974 (see Mass. R. Civ. P. 1A, par. 5), and found for the plaintiff against the companies and the Ducotts. At the trial, the auditor’s report, the testimony of two witnesses, and
