the burden of proving such contributory negligence shall rest upon the defendant. The provisions of this section shall not apply when the person or persons charged with the negligence shall die as a result of said act or acts.” This statute, enacted in 1931, was undoubtedly the result of our decision in Kotler v. Lalley, 112 Conn. 86, 151 Atl. 435, decided in 1930, in which we held that under the common law of this State, where death was claimed to be due to negligence and there was no direct testimony as to the decedent’s conduct, no inference or presumption that he was in the exercise of due care would arise from a natural instinct of self-preservation and avoidance of bodily harm; and where we stated that we had no statutory provision to enforce the “obviously just requirement” that the burden of proof in such a case should be upon the defendant. Both the history of the statute and its terms leave no doubt that in a case where it is applicable the burden to establish contributory negligence rests upon the defendant and unless the defendant does establish that defense by a fair preponderance of the evidence, the issue must be found in favor of the plaintiff. Zint v. Wheeler, 117 Conn. 484, 485, 169 Atl. 52; O'Dea v. Amodeo, 118 Conn. 58, 64, 170 Atl. 486; Breed v. Philgas Co., 118 Conn. 128, 136, 171 Atl. 14. In submitting a case to the jury where this statute applies, a trial court need not specifically refer to it or charge in terms that there is a presumption that the deceased was in the exercise of due care, if it makes clear that the effect of the statute is that which we have stated. LeCount v. Farrand, 118 Conn. 210, 212, 171 Atl. 623; Piascik v. Railway Express Agency, Inc., 119 Conn. 277, 278, 175 Atl. 919.
Early in the charge the trial court briefly and correctly stated that in such a case as this the burden was upon the defendant to prove contributory negligence
