SZYMBORSKI
v.
SLATINA
No. 22 June Term 1971, Docket No. 53,058.
Supreme Court of Michigan.
Decided December 21, 1971.
*340 Sanford N. Lakin, for plaintiffs.
Sugar, Schwartz, Silver, Schwartz & Tyler, for defendants.
T.E. BRENNAN, J.
This rear-end collision case resulted in a jury verdict of no cause for action.
Motion for new trial was made alleging that the verdict was against the great weight of the evidence; that the court erred in its charge to the jury by failing to instruct them that the statutory presumption of negligence arising from a rear-end collision could only be overcome by clear, positive and credible evidence, and by failing to instruct the jury that the defendant had the burden of proof upon the question of "sudden emergency."
The motion for new trial was denied and the Court of Appeals affirmed.
We agree. The Court of Appeals correctly disposed of the two issues as follows:
On the statutory presumption[*]:
"Where, however, we are dealing with the rearend presumption, it appears that the standard urged by the plaintiff is pertinent only to the issue of whether the presumption has been rebutted as a matter of law. Petrosky v. Dziurman (1962), 367 Mich 539, 547. This standard is one for the judge. *341 If the evidence is less than clear, positive and credible, `the question whether such presumption has been overcome should be settled  on proper instruction of course  in the jury room.' Petrosky v. Dziurman, supra, 544, 545, citing Garrigan v. LaSalle Coca-Cola Bottling Co. (1961), 362 Mich 262. The trial court did not err in refusing to instruct that the jury could find that the presumption was rebutted only upon clear, positive and credible evidence."
On sudden emergency:
"`The doctrine of sudden emergency is a "logical extension of the `reasonably prudent person' rule," and as such is not an affirmative defense. Baker v. Alt (1965), 374 Mich 492, 496. As it was said in Baker, at p 496, the "test to be applied is what that hypothetical, reasonably prudent person would have done under all the circumstances of the accident, whatever they were."' (Emphasis supplied.) Since the `sudden emergency' rule is not an affirmative defense, it was not incumbent upon the defendant to establish by a preponderance of the evidence that an emergency existed nor was it error for the judge to refuse to so charge.'"
Affirmed. Costs to appellees.
ADAMS, T.G. KAVANAGH, SWAINSON and WILLIAMS, JJ., concurred with T.E. BRENNAN, J.
T.M. KAVANAGH, C.J., and BLACK, J., concurred in the result.
WILLIAMS, J. (concurring).
I concur with my Brother T.E. BRENNAN and believe the Court of Appeals should be affirmed. However, I think it would be useful for the bench and bar to have the *342 pertinent part of the charges given by the trial court on record. The pertinent part is as follows:
"Now, I will read that statute again. The statute says in any action in any court in this state, when it is shown by competent evidence that a vehicle traveling in a certain direction overtook and struck the rear end of another vehicle proceeding in the same direction or lawfully standing on the highway, the driver or operator of such first mentioned vehicle shall be deemed prima facie guilty of negligence.
"Therefore, if you find that the defendant violated this statute before or at the time of the occurrence, then the law presumes that he was negligent. However, if you find that the defendant was confronted with a sudden emergency, not of his own making, and if you find that he used ordinary care and was still unable to avoid the occurrence because of such emergency, then this presumption of negligence is overcome.
"In deciding whether the presumption is overcome, you must weigh the presumption with all the evidence of claim of sudden emergency. If, after so weighing, you are unable to decide that the presumption has been overcome, then you must find that the defendant was negligent. If you find that the defendant was negligent, you must then decide whether such negligence was a proximate cause of the accident.
"So, the law on negligence, basically, failure to act as a reasonably prudent person under the circumstances at the time of the accident.
"In addition to that, we have, as I state, a statute that says whenever a vehicle is struck from the rear there is a prima facie evidence of the negligence on the part of the driver of the vehicle that strikes the other vehicle in the rear.
"And there is also law, as I pointed out to you, that says that if the defendant was confronted with a sudden emergency not of his own making, and he used ordinary care and was still unable to avoid *343 the occurrence because of the emergency, then the presumption is overcome.
"Then, finally, in deciding whether the presumption of negligence is overcome, you must weigh the presumption with all the evidence of claim of sudden emergency. And, if, after so weighing, you are unable to decide that the presumption has been overcome, then you must find that the defendant is negligent."
T.G. KAVANAGH, J. concurred with WILLIAMS, J.
