[p. 573] CHARLES ALVIN JONES, Chief Justice.

  The appellant was found guilty of involuntary manslaughter for the death of his competitor in the course of an automobile race between them on a highway. The trial court overruled the defendant's demurrer to the Commonwealth's evidence and, after verdict, denied his motion in arrest of judgment.  On appeal from the judgment of sentence entered on the jury's verdict, the Superior Court affirmed.  We granted allocatur because of the important question present as to whether the defendant's unlawful and reckless conduct was a sufficiently direct cause of the death to warrant his being charged with criminal homicide.

  The testimony, which is uncontradicted in material part, discloses that, on the night of the fatal accident, the defendant accepted the deceased's challenge to engage in an automobile race; that the racing took place on a rural 3-lane highway; that the night was clear and dry, and traffic light; that the speed limit on the highway was 50 miles per hour; that, immediately prior to the accident, the two automobiles were being operated at varying speeds of from 70 to 90 miles per hour; that the accident occurred in a no-passing zone on the approach to a bridge where the highway narrowed to two directionally- opposite lanes; that, at the time of the accident, the defendant was in the lead and was proceeding in his right hand lane of travel; that the deceased, in an attempt to pass the defendant's automobile, when a truck was closely approaching from the opposite direction, swerved his car to the left, crossed the highway's white dividing line and drove his automobile on the wrong side of the highway head-on into the oncoming truck with resultant fatal effect to himself.

  This evidence would of course amply support a conviction of the defendant for speeding, reckless driving [p. 574] and, perhaps, other violations of The Vehicle Code of May 1, 1929, P.L. 905, as amended.  In fact, it may be noted, in passing, that the Act of January 8, 1960, P.L. (1959) 2118, Sec. 3, 75 P.S. § 1041, amending The Vehicle Code of April 29, 1959, P.L. 58, 75 P.S. § 101 et seq., makes automobile racing on a highway an independent crime punishable by fine or imprisonment or both up to $500 and three years in jail. As the highway racing in the instant case occurred prior to the enactment of the Act of 1960, cit. supra, that statute is, of course, not presently applicable. In any event, unlawful or reckless conduct is only one ingredient of the crime of involuntary manslaughter.  Another essential and distinctly separate element of the crime is that the unlawful or reckless conduct charged to the defendant was the direct cause of the death in issue.  The first ingredient is obviously present in this case but, just as plainly, the second is not.

  While precedent is to be found for application of the tort law concept of  'proximate cause' in fixing responsibility for criminal homicide, the want of any rational basis for its use in determining criminal liability can no longer be properly disregarded.  When proximate cause was first borrowed from the field of tort law and applied to homicide prosecutions in Pennsylvania, the concept connoted a much more direct causal relation in producing the alleged culpable result than it does today.  Proximate cause, as an essential element of a tort founded in negligence, has undergone in recent times, and is still undergoing, a marked extension.  More specifically, this area of civil law has been progressively liberalized in favor of claims for damages for personal injuries to which careless conduct of others can in some way be associated.  To persist in applying the tort liability concept of proximate cause to prosecutions for criminal homicide after the marked expansion of civil liability of defendants in tort actions [p. 575] for negligence would be to extend possible criminal liability to persons chargeable with unlawful or reckless conduct in circumstances not generally considered to present the likelihood of a resultant death.

* * *

  The instant case is one of first impression in this State; and our research has not disclosed a single instance where a district attorney has ever before attempted to prosecute for involuntary manslaughter on facts similar to those established by the record now before us.  The closest case, factually, would seem to be Commonwealth v. Levin, 1957, 184 Pa.Super. 436, 135 A.2d 764, which affirmed the defendant's [p. 576] conviction of involuntary manslaughter.  In the Levin case two cars were racing on the streets of Philadelphia at speeds estimated at from 85 to 95 miles per hour.  The defendant's car, in the left hand lane, was racing alongside of the car in which the deceased was a passenger when the defendant turned his automobile sharply to the right in front of the other car thereby causing the driver of the latter car to lose control and smash into a tree, the passenger being thrown to the road and killed as a result of the impact.  It is readily apparent that the elements of causation in the Levin case were fundamentally different from those in the present case.  Levin's act of cutting his automobile sharply in front of the car in which the deceased was riding directly forced that car off of the road and into the tree.  The defendant's reckless and unlawful maneuver was the direct cause of the crucial fatality. In the instant case, the defendant's conduct was not even remotely comparable. Here, the action of the deceased driver in recklessly and suicidally swerving his car to the left lane of a 2-lane highway into the path of an oncoming truck was not forced upon him by any act of the defendant; it was done by the deceased and by him alone, who thus directly brought about his own demise. The Levin case was properly decided but it cannot, by any ratiocination, be utilized to justify a conviction in the present case.

  Legal theory which makes guilt or innocence of criminal homicide depend upon such accidental and fortuitous circumstances as are now embraced by modern tort law's encompassing concept of proximate cause is too harsh to be just.  A few illustrations should suffice to so demonstrate.

  In Mautino v. Piercedale Supply Co., 1940, 338 Pa. 435, 12 A.2d 51,--a civil action for damages--we held that where a man sold a cartridge to a person under 16 years of age in violation of a State statute and [p. 577] the recipient subsequently procured a gun from which he fired the cartridge injuring someone, the injury was proximately caused by the act of the man who sold the cartridge to the underage person. If proximate cause were the test for criminal liability and the injury to the plaintiff in the Mautino case had been fatal, the man who sold the bullet to the underage person (even though the boy had the appearance of an adult) would have been guilty of involuntary manslaughter, for his unlawful act would, according to the tort law standard, have been the proximate cause of the death.

  In Schelin v. Goldberg, 1958, 188 Pa.Super. 341, 146 A.2d 648, it was held that the plaintiff, who was injured in a fight, could recover in tort against the defendants, the owners of a taproom who prior to the fight had unlawfully served the plaintiff drinks while he was in a visibly intoxicated condition, the unlawful action of the defendants being held to be the proximate cause of the plaintiff's injuries.  Here, again, if proximate cause were the test for criminal liability and the plaintiff had been fatally injured in the fight, the taproom owners would have been guilty of involuntary manslaughter, for their unlawful act would have been no less the proximate cause of death.

  In Marchl v. Dowling & Company, 1945, 157 Pa.Super. 91, 41 A.2d 427, it was held that where a truck driver had double parked his truck and the minor plaintiff was struck by a passing car when she walked around the double parked truck, the truck driver's employer was held liable in tort for the plaintiff's injuries on the ground that the truck driver's act of double parking, which violated both a State statute and a city ordinance, was the proximate cause of the plaintiff's injuries. Here, also, if proximate cause were the test for criminal liability and the plaintiff's injuries had been fatal, the truck driver would have been guilty of involuntary manslaughter since his unlawful act [p. 578] would have been the proximate cause of the death for which his employer was held liable in damages under respondeat superior.  To be guilty of involuntary manslaughter for double parking would, of course, be unthinkable, yet if proximate cause were to determine criminal liability, such a result would indeed be a possibility.

  Even if the tort liability concept of proximate cause were to be deemed applicable, the defendant's conviction of involuntary manslaughter in the instant case could not be sustained under the evidence.  The operative effect of a supervening cause would have to be taken into consideration. Commonwealth v. Redline, supra, 391 Pa. at page 505, 137 A.2d at page 481. But, the trial judge refused the defendant's point for charge to such effect and erroneously instructed the jury that 'negligence or want of care on the part of [the deceased] is no defense to the criminal responsibility of the defendant * * *.'

* * *

 Under the uncontradicted evidence in this case, the conduct of the defendant was not the proximate cause of the decedent's death as a matter of law.  In Kline v. Moyer and Albert, 1937, 325 Pa. 357, 364, 191 A. 43, 46, 111 A.L.R. 406, the rule is stated as follows: 'Where a second actor has become aware of the existence of a potential danger created by the negligence of an original tort-feasor, and thereafter, by an independent act of negligence, brings about an accident, the first tort-feasor is relieved of liability, because the condition created by him was merely a circumstance of the accident and not its proximate cause.'  See, in accord, DeLuca v. Manchester Laundry & Dry Cleaning Company, Inc., 1955, 380 Pa. 484, 491, 112 A.2d 372; Jeloszewski v. Sloan, 1953, 375 Pa. 360, 365, 100 A.2d 480; Johnson [p. 580] v. Angretti, 1950, 364 Pa. 602, 606-607, 73 A.2d 666.

  In the case last above cited, while Angretti was driving his truck eastward along a highway, a bus, traveling in the same direction in front of him, stopped to take on a passenger.  Angretti swerved his truck to the left into the lane of oncoming traffic in an attempt to pass the bus but collided with a tractor-trailer driven by the plaintiff's decedent, who was killed as a result of the collision.  In affirming the entry of judgment n. o. v. in favor of the defendant bus company, we held that any negligence on the part of the bus driver, in suddenly bringing his bus to a halt in order to pick up a passenger, was not a proximate cause of the death of the plaintiff's decedent since the accident 'was due entirely to the intervening and superseding negligence of Angretti in allowing his truck to pass over into the pathway of the westbound tractortrailer * * *.'

  In the case now before us, the deceased was aware of the dangerous condition created by the defendant's reckless conduct in driving his automobile at an excessive rate of speed along the highway but, despite such knowledge, he recklessly chose to swerve his car to the left and into the path of an oncoming truck, thereby bringing about the head-on collision which caused his own death.

 To summarize, the tort liability concept of proximate cause has no proper place in prosecutions for criminal homicide and more direct causal connection is required for conviction.  Commonwealth v. Redline, supra, 391 Pa. at pages 504-505, 137 A.2d at page 480.  In the instant case, the defendant's reckless conduct was not a sufficiently direct cause of the competing driver's death to make him criminally liable therefor.

  The judgment of sentence is reversed and the defendant's motion in arrest of judgment granted.

  [p. 581] BELL, Justice (concurring).

  I concur in the result reached by the majority opinion.  I also agree that in recent years the doctrine of tort liability in civil cases has been extended and stretched to such an extent that it should no longer be applied in criminal cases.  This is especially necessary because the tests for involuntary manslaughter, particularly in cases arising out of automobile accidents, have been different and varying in the Superior Court and in the lower Courts, with no clear standard.  This was due to an attempt by these Courts to apply a proper test to the different circumstances of each particular case.  For example the following tests have been applied by the Superior Court:  Rash or reckless conduct; proximate cause; legal cause; substantial factor; natural and probable consequence such as should have been foreseen; efficient cause; concurring cause; must be more than remote cause--substantial factor; natural result or probable consequence.

  What is involuntary manslaughter?  Involuntary manslaughter is a misdemeanor and is very different from murder and from voluntary manslaughter.  The prime difference between murder, voluntary manslaughter, and involuntary manslaughter may be thus summarized: Murder is an unlawful killing of another person with malice aforethought, expressed or implied.  Commonwealth v. Nelson, 396 Pa. 359, 152 A.2d 913; Commonwealth v. Buzard, 365 Pa. 511, 76 A.2d 394, 22 A.L.R.2d 846; Commonwealth v. Bolish, 381 Pa. 500, 113 A.2d 464.

  Voluntary manslaughter is the intentional killing of another person which is committed under the influence of passion. Commonwealth v. Nelson, 396 Pa. 359, 152 A.2d 913, supra; Commonwealth v. Donough, 377 Pa. 46, 103 A.2d 694; Commonwealth v. Palermo, 368 Pa. 28, 81 A.2d 540.

  Involuntary manslaughter is an unintentional and nonfelonious killing of another person without malice or passion,1 which results from conduct by defendant which is so unlawful as to be outrageous, provided such conduct is a direct cause of the killing.

  [p. 583] The unlawful racing by this defendant was not only unlawful, it was outrageous, [n. 3] but it was not a direct cause, i. e., one of the direct causes, of the killing.
 

3.  For this reprehensible conduct defendant can and should be punished.

  EAGEN, Justice (dissenting).

  The opinion of the learned Chief Justice admits, under the uncontradicted facts, that the defendant, at the time of the fatal accident involved, was engaged in an unlawful and reckless course of conduct.  Racing an automobile at 90 miles per hour, trying to prevent another automobile going in the same direction from passing him, in a no-passing zone on a two-lane public highway, is certainly all of that.  Admittedly also, there can be more than one direct cause of an unlawful death.  To me, this is selfevident.  But, says the majority opinion, the defendant's recklessness was not a direct cause of the death.  With this, I cannot agree.

  If the defendant did not engage in the unlawful race and so operate his automobile in such a reckless manner, this accident would never have occurred.  He helped create the dangerous event. He was a vital part of it.  The victim's acts were a natural reaction to the stimulus of the situation.  The race, the attempt to pass the other car and forge ahead, the reckless speed, all of these factors the defendant himself helped create.  He was part and parcel of them. That the victim's response was normal under the circumstances, that his reaction should have been expected and was clearly foreseeable, is to me beyond argument.  That the defendant's recklessness was a substantial factor is obvious.  All of this, in my opinion, makes his unlawful conduct a direct cause of the resulting collision.

* * *

  The majority opinion states, 'Legal theory which makes guilt or innocence of criminal homicide depend upon such accidental and fortuitous circumstances as are now embraced by modern tort law's encompassing concept * * * is too harsh to be just.'  If the resulting death had been dependent upon 'accidental and fortuitous circumstances' or, as the majority also say, 'in circumstances not generally considered to present the likelihood of a resultant death,' we would agree that [p. 587] the defendant is not criminally responsible.  However, acts should be judged by their tendency under the known circumstances, not by the actual intent which accompanies their performance.  Every day of the year, we read that some teen-agers, or young adults, somewhere in this country, have been killed or have killed others, while racing their automobiles.  Hair- raising, death-defying, law-breaking rides, which encompass 'racing' are the rule rather than the exception, and endanger not only the participants, but also every motorist and passenger on the road.  To call such resulting accidents 'accidental and fortuitous,' or unlikely to result in death, is to ignore the cold and harsh reality of everyday occurrences.  Root's actions were as direct a cause of Hall's death as those in the 'shield' cases. Root's shield was his high speed and any approaching traffic in his quest to prevent Hall from passing, which he knew Hall would undertake to do, the first time he thought he had the least opportunity.

  1 Wharton, Criminal Law And Procedure § 68 (1957), speaking of causal connections, says:  'A person is only criminally liable for what he has caused, that is, there must be a causal relationship between his act and harm sustained for which he is prosecuted.  It is not essential to the existence of a causal relationship that the ultimate harm which has resulted was foreseen or intended by the actor.  It is sufficient that the ultimate harm is one which a reasonable man would foresee as being reasonably related to the acts of the defendant.'  Section 295, in speaking about manslaughter, says:  'When homicide is predicated upon the negligence of the defendant, it must be shown that his negligence was the proximate cause or a contributing cause of the victim's death.  It must appear that the death was not the result of misadventure, but the natural and probable result of a reckless or culpably negligent act.  To render a person criminally liable for negligent [p. 588] homicide, the duty omitted or improperly performed must have been his personal duty, and the negligent act from which death resulted must have been his personal act, and not the act of another.  But he is not excused because the negligence of someone else contributed to the result, when his act was the primary or proximate cause and the negligence of the other did not intervene between his act and the result.'

  Professor Joseph Beale, late renowned member of the Harvard Law School faculty, in an article entitled, The Proximate Consequence of an Act, 33 Harv.L.Rev. 633, 646, said, 'Though there is an active force intervening after defendant's act, the result will nevertheless be proximate if the defendant's act actually caused the intervening force.  In such a case the defendant's force is really continuing in active operation by means of the force it stimulated into activity.'  Professor Beale, at 658, sums up the requirements of proximity of result in this manner:  '1.  The defendant must have acted (or failed to act in violation of a duty).  2.  The force thus created must (a) have remained active itself or created another force which remained active until it directly caused the result; or (b) have created a new active risk of being acted upon by the active force that caused the result.'  2 Bishop, New Criminal Law § 424 (1913), says:  'He whose act causes in any way, directly or indirectly, the death of another, kills him, within the meaning of felonious homicide.  It is a rule of both reason and the law that whenever one's will contributes to impel a physical force, whether another's, his own, or a combined force, proceeding from whatever different sources, he is responsible for the result, the same as though his hand, unaided, had produced it.'

  But, says the majority opinion, these are principles of tort law and should not in these days be applied to the criminal law.  But such has been the case since the [p. 589] time of Blackstone.  These same principles have always been germane to both crimes and tort.  See, Beale, Recovery for Consequence of an Act, 9 Harv.L.Rev. 80; Greene, Rationale of Proximate Cause, 132-133 (1927); Frederick C. Moesel, Jr., A Survey of Felony Murder, 28 Temp.L.Q. 453, 459- 466.  They have been repeatedly so applied throughout the years and were employed in a criminal case in Pennsylvania as long as one hundred and seventeen years ago. See, Commonwealth v. Hare, 1844, 2 Clark 467.  In that case, two separate bands of men were fighting each other with firearms in a public street and, as a result, an innocent citizen was shot and killed.  The person firing the fatal shot could not be ascertained.  Hare, one of the rioters, was convicted of homicide and the judgment was affirmed. Can anyone question the logic or correctness of this decision? Under the rationale of the majority opinion, what would be the result in the Hare case?  Certainly, under its reasoning, if the truck driver met death under the circumstances the case at hand presents, the defendant would not be legally responsible.  Again with this conclusion, I cannot agree.

  While the victim's foolhardiness in this case contributed to his own death, he was not the only one responsible and it is not he alone with whom we are concerned.  It is the people of the Commonwealth who are harmed by the kind of conduct the defendant pursued.  Their interests must be kept in mind.

  I, therefore, dissent and would accordingly affirm the judgment of conviction.
