ered the issue as to whether the Pennsylvania presumption of due care extends to one who has died subsequent to an accident from causes unrelated to it.
That being so, “it is incumbent on us to make our own determination of what the Pennsylvania Supreme Court would probably rule in a similar case.” Gerr v. Emrick, 283 F.2d 293, 294 (3 Cir. 1960).
We are of the opinion that the Pennsylvania Supreme Court would hold that the presumption of due care does not enure to the benefit of one who dies, or is bereft of his memory, from causes unrelated to the accident on which a suit is based. We are compelled to that conclusion by the rationale of the Pennsylvania cases which is the premise of the Pennsylvania presumption. The rationale is explicitly stated in Morin viz. “there is a presumption arising from the general knowledge of the strength of the instinct of self-preservation and the natural desire to avoid pain and injury to oneself that the deceased at the time of the accident was exercising due care,” and in the recent case of Kmetz v. Lochiatto, 421 Pa. 363, at pages 366-367, 219 A.2d 588, at pages 589-590 (decided May 24, 1966) where it was said:
“Where a plaintiff is rendered incompetent as a result of injuries he sustained, a presumption of due care follows: ‘Where a plaintiff’s mind is a blank as to an accident and all its incidents, the presumption is that he did all that the law required him to do and was not guilty of contributory negligence.’ Auel v. White, 389 Pa. 208, 214, 132 A.2d 350.” (Emphasis supplied.)
It is pertinent to note that the District Court for the Western District of Pennsylvania recently ruled that the Pennsylvania presumption of due care only extends where one involved in an accident “die as a result of said accident.” Brain v. Elliott-Spicher Motors, Inc., 249 F.Supp. 695 (1966).
We come now to the plaintiff’s second point, viz. that the trial court erred in excluding the testimony of Jason A. Martin, with reference to the accident here involved, in the course of the state criminal proceeding earlier referred to. We agree with the plaintiff’s contention that the trial court erred in excluding this testimony.
Martin testified in the state proceeding as to his role in the accident here involved. Under the settled law in Pennsylvania, which is in accord with the general view, what he said in his testimony is an admission against interest and as. such was admissible in the instant proceeding. In Muzychuk, to Use and Benefit of Burns v. Yellow Cab Company, 343 Pa. 335, 341, 22 A.2d 670, 673 (1941) the Court said:
“ ‘A party’s testimony, if voluntarily given * may be used against him as admissions, not only in the particular case, but in any subsequent proceedings in which they are relevant •»’. Henry, Pennsylvania Trial Evidence, 3d Ed., section 65. See also Truby v. Seybert, 12 Pa. 101, 103; Charles v. Arrington, 110 Pa.Super. 173, 177, 167 A. 428.”
To the same effect see Heyman v. Hanauer, 302 Pa. 56, 61, 152 A. 910, 911-912 (1930).
Martin’s testimony was clearly relevant to the issue involved in the instant case, viz., whether he was negligent. In it he said that he first saw the Stalcup car while it “was turning into, towards the motel” when he was more than 300 feet away; there was then no traffic between his car and the Stalcup car; he was then proceeding at a speed of 50 miles an hour; he didn’t apply his brakes until he was “about 15 feet” away, and the front end of his car struck the right rear of the Stalcup car.
The fact that Jason A. Martin has died does not affect the admissibility of his testimony since the Administrator is his successor in interest and as such the admission is admissible against him. See Hughes v. The President, Managers and Company of the Delaware & Hudson Canal Co., 176 Pa. 254, 35 A. 190 (1896).
