MR. JUSTICE MORAN
delivered the opinion of the court:
These two cases, consolidated for appeal, present a question which arises solely from the pleadings. In each, plaintiff’s complaint included a count based on the doctrine of comparative negligence, which count was dismissed by the trial court on motion by the defendants. In Alvis v. Ribar, the appellate court affirmed summarily, stating, “*** it is not for this court to attempt to reverse the many cases and opinions of the Illinois Supreme Court in this area.” (78 Ill. App. 3d 1117, 1119.) This court allowed leave to appeal. In Krohn v. Abbott Laboratories, Inc., we granted a motion for direct appeal under Rule 302(b) (73 Ill. 2d 302(b)).
Plaintiffs ask this court to abolish the doctrine of contributory negligence and to adopt in its place the doctrine of comparative negligence as the law in Illinois.
In Alvis v. Ribar, a motor vehicle operated by defendant Ribar skidded out of control and collided with a metal barrel which anchored an official intersection stop sign. The sign had been temporarily placed at the intersection while construction work on the intersecting road was being done by the defendant contractor, Milburn Brothers, Inc., under the supervision of defendant Cook County. Plaintiff Alvis, who was a passenger in defendant Ribar’s vehicle, sustained injuries as a result of the collision. He filed a multicount personal injury complaint seeking damages from all three defendants.
In Krohn v. Abbott Laboratories, Inc., a tractor trailer operated by defendant Sweetwood and owned by defendant Abbott Laboratories, Inc., was traveling west when it collided with an eastbound vehicle operated by decedent, Klaus D. Krohn. The collision occurred in the eastbound lane. As a result of the collision, Klaus D. Krohn sustained fatal injuries. Plaintiff, Karin D. Krohn, as administrator of the estate of Klaus D. Krohn, brought a wrongful death action in the circuit court of Lake County against both defendants.
I
THE HISTORY OF CONTRIBUTORY NEGLIGENCE
Generally, under the doctrine of contributory negligence, a plaintiff is barred from recovering compensation for his injuries if his negligence contributed to the accident. The origin of the doctrine can be traced to the case of Butterfield v. Forrester (1809), 11 East 60, 103 Eng. Rep. 926. There defendant had placed a pole across part of a public road. Plaintiff, riding his horse too fast to see the obstruction, rode into the pole and was injured. The concept of contributory negligence was created by the words of Chief Justice Lord Ellenborough:
“Two things must concur to support this action, an obstruction in the road by the fault of the defendant, and no want of ordinary care to avoid it on the part of the plaintiff.” Butterfield v. Forrester (1809), 11 East 60, 61, 103 Eng. Rep. 926, 927.
The doctrine was swiftly adopted in American jurisprudence, commencing with the case of Smith v. Smith (1824), 19 Mass. (2 Pick.) 621, 13 Am. Dec. 464. (See H. Woods, The Negligence Case: Comparative Fault 7 (1978); Turk, Comparative Negligence on the March, 28 Chi.-Kent L. Rev. 189, 198 (1950).) Legal scholars attribute the swift and universal acceptance of the doctrine to newly formed industry’s need for protection “against the ravages which might have been wrought by over-sympathetic juries.” (Turk, Comparative Negligence on the March, 28 Chi.-Kent L. Rev. 189, 201 (1950); H. Woods, The Negligence Case: Comparative Fault 8 (1978). Also see Scott v. Rizzo (1981), 96 N.M. 682, 685, 634 P.2d 1234, 1237; Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 437.) Judicial concern was particularly evident in the area of personal injury suits brought by railroad employees against the railroads. The courts realized that, in the pervading public view that saw railroads as “harmful entities with deep pockets” (H. Woods, The Negligence Case: Comparative Fault 9 (1978)), juries’ sympathies toward plaintiffs could wreak financial disaster upon the burgeoning industry.
Case law developed the doctrine of contributory negligence in Illinois. In Aurora Branch R.R. Co. v. Grimes (1852), 13 Ill. 585, 587-88, this court followed the Butter-field case and added the requirement that the burden of proof is upon the plaintiff to show not only negligence on the part of the defendant, but also that plaintiff himself exercised proper care and circumspection. In the next few years the decisions involving “last clear chance” (Moore v. Moss (1852), 14 Ill. 106, 110 (later discussed)), degrees of negligence (Chicago & Mississippi R.R. Co. v. Patchin (1854), 16 Ill. 198, 203), and proximate cause (Joliet & Northern Indiana R.R. Co. v. Jones (1858), 20 Ill. 221, 227) created confusion. Mr. Justice Breese reviewed these decisions in Galena & Chicago Union R.R. Co. v. Jacobs (1858), 20 Ill. 478, a case which involved a 414-year-old boy who had been run over by a railroad locomotive. There the court ultimately disagreed with the Butterfield holding and adopted a form of comparative negligence in its place.
“This, and all the cases subsequent, to which we have referred, have one common basis, and that is found in the old law maxim that ‘no man shall take advantage of his own wrong or negligence’ in his prosecution or defense against another.” (Galena & Chicago Union R.R. Co. v. Jacobs (1858), 20 Ill. 478, 490-91.)
The court concluded that liability does not depend absolutely on the absence of all negligence on the part of the plaintiff but upon the relative degrees of care or want of care manifested by both parties.
“ [A] 11 care or negligence is at best but relative, the absence of the highest possible degree of care showing the presence of some negligence, slight as it may be. The true doctrine, therefore, we think is, that in proportion to the negligence of the defendant, should be measured the degree of care required of the plaintiff — -that is to say, the more gross the negligence manifested by the defendant, the less degree of care will be required of the plaintiff to enable him to recover. Although these cases do not distinctly avow this doctrine in terms, there is a vein of it very perceptible, running through very many of them, as, where there are faults on both sides, the plaintiff shall recover, his fault being to be measured by the defendant’s negligence, the plaintiff need not be wholly without fault ***.
We say, then, that in this, as in all like cases, the degrees of negligence must be measured and considered, and wherever it shall appear that the plaintiff’s negligence is comparatively slight, and that of the defendant gross, he shall not be deprived of his action.” (Galena & Chicago Union R.R. Co. v. Jacobs (1858), 20 Ill. 478, 497.)
Thus, in 1858, Illinois became a State which followed the doctrine of comparative negligence.
In 1870, in the case of Illinois Central R.R. Co. v. Baches (1870), 55 Ill. 379, 389-90, the court held:
“The seventh of appellee’s instructions is not accurate, as it nowhere limits or defines the duty of deceased. Under this instruction, the jury were required to find for the plaintiff, although deceased might have been guilty of negligence equal to that of appellants. Such has never been recognized as the rule of law in this class of cases. *** [W] e are not inclined to extend the rule, as there is no warrant in the common law for allowing the plaintiff any greater latitude. He should use prudence and care, but failing to do so, and is guilty of negligence, he can not recover, unless the negligence of the defendant clearly and largely exceeds his. This instruction should have been refused, or modified so as to announce the rule of comparative negligence before it was given.”
In the case of Illinois Central R.R. Co. v. Hammer (1874), 72 Ill. 347, 351, the court attempted to clarify the definition of comparative negligence. “The rule on this subject, it may be, has not at all times been accurately stated by this court. By inadvertence, it has been loosely and indefinitely stated in some of the cases, but what the court has held, and still holds, is, that a plaintiff free from all negligence may recover from a defendant who has failed to use such care as ordinarily prudent men generally employ; or, a plaintiff who is even guilty of slight negligence may recover of a defendant who has been grossly negligent, or whose conduct has been wanton or wilful. Hence the doctrine of comparative negligence.”
In 1878, in the case of Indianapolis & St. Louis R.R. Co. v. Evans (1878), 88 Ill. 63, 65, the court adhered to the principles of Baches.
“ Tt is the duty of a railroad company to take all reasonable precaution for the protection of life and limb from injuries by their cars; and if such precautions are not taken, a person injured in consequence thereof *** has a just cause of complaint, and is entitled to recover damages for any injury sustained by reason of the omission of the company to adopt all reasonable guards against liability to injury, unless such injury is caused by the negligence of the party injured equal to or greater than that of the party committing the injury.’
This seventh instruction, in substance, says, that plaintiff’s action can not be defeated by his own negligence, unless such negligence be at least equal to that of defendant. This is not the law. The true rule on this subject is laid down in Illinois Central Railroad Co. v. Baches, Admr. 55 Ill. 379, and need not be further discussed here.”
Thus developed the doctrine that the negligence of the plaintiff would not bar his recovery if it was “slight,” in the sense of a “degree of negligence less than a failure to exercise ordinary care,” while the negligence of the defendant was “gross” in comparison. (Wabash, St. Louis & Pacific Ry. Co. v. Moran (1883), 13 Ill. App. 72, 76.) No attempt was made to divide the damages under this “comparative negligence” rule, and where it was applied the effect was full recovery by the plaintiff. The injured person was required to show not only that his negligence was slight and that the defendant’s negligence was gross, but also that they were so when compared with each other, since the element of comparison was the essence of the doctrine. Chicago, Milwaukee & St. Paul Ry. Co. v. Mason (1888), 27 Ill. App. 450, 453, 454.
During the next 27 years, the rule stated in Jacobs was followed and then abandoned by this court in Calumet Iron & Steel Co. v. Martin (1885), 115 Ill. 358, 368-69, and City of Lanark v. Dougherty (1894), 153 Ill. 163, 165-66, where it unequivocally made any contributory negligence on the part of the plaintiff a complete bar to recovery. Dean Green summarized the reasons for abandonment: the formula was not complete in that the “degrees of negligence” did not mitigate the damages which the plaintiff could recover; the “degrees of negligence” resulted in doctrinal conflict and confusion; and the Jacobs case had not overruled the Grimes case, so that, during the lifetime of the Jacobs decision, courts of appeal could still rely upon the failure of the plaintiff to prove that he had exercised ordinary care in his own behalf before allowing recovery on a comparative negligence basis. Green, Illinois Negligence Law, 39 Ill. L. Rev. 36, 47-51 (1944).
Other jurisdictions found problems in the doctrine of contributory negligence. Criticism of the harshness of the doctrine came as swiftly as did its acceptance into the law, and courts found exceptions to soften that harshness.
The first exception formulated to the rule of contributory negligence was that the negligence of the plaintiff was no defense when the defendant’s conduct was “wilful,” “wanton,” or “reckless.” (Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 5 (1953); Bradley v. Appalachian Power Co. (W. Va. 1979), 256 S.E.2d 879, 882; Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 437; Kirby v. Larson (1977), 400 Mich. 585, 616, 256 N.W.2d 400, 415.) This rule, however, was found to be cumbersome and difficult to apply. Historically, it is of limited importance.
The second exception that developed was limited to cases involving a defendant’s violation of a statute designed to protect the plaintiff even against his own improvident acts. Since only a minute number of cases involved such statutes, the exception did little to alleviate the plight of the negligent plaintiff. Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 5-6 (1953).
Greater relief was found in the creation of a third exception — “last clear chance” — which originated in the 1842 case of Davies v. Mann (1842), 10 M. & W. 546, 152 Eng. Rep. 588. In Davies, the defendant negligently ran into plaintiff’s donkey, which plaintiff had left fettered in the highway. The court ruled that plaintiff’s negligence in leaving the donkey in the road did not bar his claim for damages against defendant, since defendant had the “last clear chance” to avoid the accident. The basic concept resembles the effect of a superseding event nullifying the negligence of a plaintiff. Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 6-7 (1953).
The application of the third exception has by no means been uniform. Dean Prosser suggested that “ [t] he real explanation would appear to be nothing more than a dislike for the defense of contributory negligence, and a rebellion against its application in a group of cases where its hardship is most apparent.” (Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 7 (1953).) Illinois courts have expressly found the doctrine of “last clear chance” not to be the law of the State. (Specht v. Chicago City Ry. Co. (1924), 233 Ill. App. 384. Contra, Moore v. Moss (1852), 14 Ill. 106.) Dean Prosser has stated that although the doctrine has been repudiated in this State, it is nonetheless employed without labeling. Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 8 (1953). See Walldren Express & Van Co. v. Krug (1920), 291 Ill. 472, 477, employing the phrase “conscious indifference to consequences.”
Comparative negligence made its first permanent entry into American law in 1908 in the form of the Federal Employers’ Liability Act (45 U.S.C. sec. 53). The Act applied to all negligence cases for injuries sustained by railroad employees engaged in interstate commerce, whether such cases were brought in a State or a Federal court. The concept of comparative negligence provided that the contributory negligence of the employee would not act as a bar to recovery, but that recovery would be diminished in proportion to the amount of negligence attributable to him. (Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 11-12 (1953); V. Schwartz, Comparative Negligence 11 (1974); H. Woods, The Negligence Case: Comparative Fault 24, 29 (1978).) The introduction of the Federal Employers’ Liability Act was the catalyst for a flood of State statutes which established a comparative negligence standard for injuries to laborers, and, especially, for railroad employees. Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 12-13 (1953).
In 1920, Congress adopted comparative negligence for cases arising under the Jones Act (Act of June 5, 1920, ch. 250, sec. 33, 41 Stat. 1007, 46 U.S.C. sec. 688) and under the Death on the High Seas Act (Act of March 30, 1920, ch. Ill, sec. 6, 41 Stat. 537, 46 U.S.C. sec. 766). See Prosser, Comparative Negligence, 41 Cal L. Rev. 1, 12 (1953); V. Schwartz, Comparative Negligence 11, (1974); H. Woods, The Negligence Case: Comparative Fault 52 (1978); Kaatz v. State (Alaska 1975), 540 P.2d 1037, 1047.
In 1910, Mississippi became the first State to adopt a comparative negligence statute applicable to negligence cases generally. (Miss. Code Ann. sec. 11 — 7—15 (1972).) The statute adopted the “pure” form of comparative negligence under which each responsible party would pay for the injuries sustained according to the relative percentage of his fault. Another form of comparative negligence was enacted by Wisconsin in 1931. (Wis. Stat. Ann. sec. 895.045 (West 1966).) This “modified” form allowed a negligent plaintiff to recover for his injuries only if his negligence was “not as great as that of the defendant.”
Today, a total of 36 States have adopted comparative negligence. The following is a list of States which have adopted the doctrine, indicating its source and form.

(Note: Missouri adopted comparative “fault” in third-party noncontractual indemnity actions by judicial decision in Missouri Pacific R.R. Co. v. Whitehead & Kales Co. (Mo. 1978), 566 S.W.2d 466.)
Twenty-three States have adopted the Wisconsin “modified” approach. Ten States have adopted the Mississippi “pure” comparative negligence approach. Two States, Nebraska and South Dakota, have a system which allows the plaintiff to recover only if his negligence is “slight” and that of defendant’s is “gross.” Georgia has its own unique system. It is important to note that 29 of these 36 States have adopted comparative negligence in the last 12 years.
In England, the birthplace of Butterfield v. Forrester, the concept of contributory negligence was long ago abandoned and replaced by a system of comparative negligence. (Maki v. Frelk (1967), 85 Ill. App. 2d 439, 448, rev’d on other grounds (1968), 40 Ill. 2d 193.) Similarly, in many jurisdictions outside the United States the rule of contributory negligence has been abandoned in favor of comparative negligence. (Canada, the Canal Zone, Switzerland, Spain, Portugal, Austria, Germany, France, the Philippines, Japan, Russia, New Zealand, West Australia, Poland, and Turkey. See H. Woods, The Negligence Case: Comparative Fault 17 (1978); Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 2 (1953); Turk, Comparative Negligence on the March, 28 Chi.-Kent L. Rev. 189, 238-45 (1950).) In light of these changes the Supreme Court of Michigan, in Placek v. City of Sterling Heights (1979), 405 Mich. 638, 653, 275 N.W.2d 511, 515, stated:
“This precedent is so compelling that the question before remaining courts and legislatures is not whether but when, how and in what form to follow this lead.”
II
CONTRIBUTORY NEGLIGENCE v. COMPARATIVE NEGLIGENCE
The contributory negligence defense has been subject to attack because of its failure to apportion damages according to the fault of the parties. Under a comparative negligence standard, the parties are allowed to recover the proportion of damages not attributable to their own fault. The basic logic and fairness of such apportionment is difficult to dispute.
The defendants herein claim that no change of circumstances has been shown which would call for a change from the established doctrine of contributory negligence. The Illinois Defense Counsel, in its amicus curiae brief, relies on the words of Mr. Justice Powell for the proposition that change is not demanded by the public.
“[T]here is little evidence that the public generally is concerned. If indeed the present rule is as ‘archaic’ and ‘unjust’ as is contended, one would normally expect much greater support for the organized efforts being made to abolish it.” Powell, Contributory Negligence: A Necessary Check on the American Jury, 43 A.B.A.J. 1005, 1008 (1957).
It must be noted, however, that at the time of Mr. Justice Powell’s quoted assessment, only six States had adopted the doctrine of comparative negligence. That 30 additional States have since adopted the doctrine evidences that the basis for the assessment has changed and that today there is, indeed, a compelling public demand to abolish the old rule. Certainly, the concern which prompted the adoption of the rule can no longer support its retention. There is no longer any justification for providing the protective barrier of the contributory negligence rule for industries of the nation at the expense of deserving litigants. (Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 437.) It must be pointed out that today most cases against industrial defendants are brought under the Worker’s Compensation Act, under which plaintiff’s negligence is not an issue. (Ill. Rev. Stat. 1979, ch. 48, par. 138.1 et seq.; Maki v. Frelk (1967), 85 Ill. App. 2d 439, 441, rev’d on other grounds (1968), 40 Ill. 2d 193.) The United States Supreme Court recognized the obsolescence of the rule in relation to present-day needs in one sphere of the law:
“The harsh rule of the common law under which contributory negligence wholly barred an injured person from recovery is completely incompatible with modem admiralty policy and practice.” (Pope & Talbot v. Hawn (1953), 346 U.S. 406, 408-09, 98 L. Ed. 143, 150, 74 S. Ct. 202, 204.)
We believe that the concept of comparative negligence which produces a more just and socially desirable distribution of loss is demanded by today’s society.
Defendants contend that the apportionment of relative fault by a jury cannot be scientifically done, as such precise measurement is impossible. The simple and obvious answer to this contention is that in 36 jurisdictions of the United States such apportionment is being accomplished by juries. The Supreme Court of California, in responding to a similar contention, stated:
“These inherent difficulties are not, however, insurmountable. Guidelines might be provided the jury which will assist it in keeping focussed upon the true inquiry [citation], and the utilization of special verdicts or jury interrogatories can be of invaluable assistance in assuring that the jury has approached its sensitive and often complex task with proper standards and appropriate reverence.” (Li v. Yellow Cab Co. (1975), 13 Cal. 3d 804, 824, 532 P.2d 1226, 1240, 119 Cal. Rptr. 858, 872.)
We agree that such guidelines can assist a jury in making apportionment decisions and view the necessary subtle calculations no more difficult or sophisticated for jury determination than others in a jury’s purview, such as compensation for pain and suffering. Although it is admitted that percentage allocations of fault are only approximations, the results are far superior to the “all or nothing” results of the contributory negligence rule. “Small imperfections can be disregarded, small inequities tolerated, if the final result is generally satisfactory.” Turk, Comparative Negligence on the March, 28 Chi.-Kent L. Rev. 189, 341-42 (1950).
Defendants assert that the contributory negligence rule should be retained in that the comparative negligence doctrine rewards carelessness and ignores the value of requiring prudent behavior. The fallacy of this premise was underscored by Dean Prosser:
“[T]he assumption that the speeding motorist is, or should be meditating on the possible failure of a lawsuit for his possible injuries lacks all reality, and it is quite as reasonable to say that the rule promotes accidents by encouraging the negligent defendant.” (Prosser, Comparative Negligence, 41 Cal. L. Rev. 1,4 (1953).)
(See Li v. Yellow Cab Co. (1975), 13 Cal. 3d 804, 811 n.4, 532 P.2d 1226, 1231 n.4, 119 Cal. Rptr. 858, 863 n.4; Kaatz v. State (Alaska 1975), 540 P.2d 1037, 1048; Kirby v. Larson (1977), 400 Mich. 585, 619 n.29, 256 N.W.2d 400, 416 n.29.) Contrary to defendants’ assertion, we believe that the need to deter negligent parties supports the adoption of the comparative negligence doctrine in which each party would be liable for damages in direct proportion to his degree of carelessness.
Defendants claim that the change to comparative negligence will cause administrative difficulties due to an increase in claims, a decrease in settlements, and a resulting overcrowded docket. An Arkansas study showed that, there, the adoption of comparative negligence prompted no drastic change in court burden; that the change increased potential litigation but promoted more pretrial settlements. The report concluded that concern over court congestion should not be a factor in a State’s decision to adopt comparative negligence. Rosenberg, Comparative Negligence in Arkansas; A “Before and After” Survey, 13 Ark. L. Rev. 89, 108 (1959). See Also Note, Comparative Negligence — A Survey of the Arkansas Experience, 22 Ark. L. Rev. 692 (1969).
In United States v. Reliable Transfer Co. (1975), 421 U.S. 397, 44 L. Ed. 2d 251, 95 S. Ct. 1708, wherein the court adopted apportionment of damages over the previous rule of divided damages in admiralty, the court addressed an argument similar to that posited by defendants herein.
“[Defendants ask] us to continue the operation of an archaic rule because its facile application out of court yields quick, though inequitable, settlements, and relieves the courts of some litigation. Congestion in the courts cannot justify a legal rule that produces unjust results in litigation simply to encourage speedy out-of-court accommodations.” (United States v. Reliable Transfer Co. (1975), 421 U.S. 397, 408, 44 L. Ed. 2d 251, 261, 95 S. Ct. 1708, 1714.)
We believe that the defendants’ fears concerning the judicial administrative problems attendant upon the adoption of comparative negligence are exaggerated. (Kaatz v. State (Alaska 1975), 540 P.2d 1037, 1048; Scott v. Rizzo (1981), 96 N.M. 682, 687, 634 P.2d 1234, 1239.) But were defendants’ fears well founded, we could nevertheless not allow the contributory negligence rule to remain the law of this State in the face of overwhelming evidence of its harsh and unjust results.
Defendants’ claim that the adoption of comparative negligence would escalate insurance rates to an unbearable level. This has not been found to be the case. Effects, in fact, have been found to be minimal. Rosenberg, Comparative Negligence in Arkansas: A “Before and After” Survey, 13 Ark. L. Rev. 89, 108 (1959). See V. Schwartz, Comparative Negligence 338 (1974); Fleming, Foreword: Comparative Negligence at Last — By Judicial Choice, 64 Cal. L. Rev. 239, 243-44 (1976).
The amicus curiae brief submitted by the Illinois Defense Counsel suggests that, under the contributory negligence rule, the jury has sufficient flexibility to do substantial justice and that this flexibility negates the necessity for the adoption of comparative negligence. In essence, the Illinois Defense Counsel alludes to the oft-observed phenomenon that, once inside the jury room, juries often ignore the harshness of the contributory negligence rule and, instead, dole out justice by a common sense approach according to the relative culpability of the litigants. We agree that such may be the case and, in fact, find the proclivity of juries to ignore the law to be a compelling reason for the abolition of that law. The Supreme Court of Florida addressed this concern.
“[T]here is something basically wrong with a rule of law that is so contrary to the settled convictions of the lay community that laymen will almost always refuse to enforce it, even when solemnly told to do so by a judge whose instructions they have sworn to follow.
The disrespect for law engendered by putting our citizens in a position in which they feel it is necessary to deliberately violate the law is not something to be lightly brushed aside; and it comes ill from the mouths of lawyers, who as officers of the courts have sworn to uphold the law, to defend the present system by arguing that it works because jurors can be trusted to disregard that very law.” (Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 437.)
There is something inherently wrong with a rule of law so repulsive to a jury’s common sense of justice that veniremen feel compelled to ignore the law. Scott v. Rizzo (1981), 96 N.M. 682, 689, 634 P.2d 1234, 1241; Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 437; Li v. Yellow Cab Co. (1975), 13 Cal. 3d 804, 811, 532 P.2d 1226, 1231, 119 Cal. Rptr. 858, 863; Fleming, Foreword: Comparative Negligence at Last — By Judicial Choice, 64 Cal. L. Rev. 239, 242-43 (1976); Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 4 (1953).
HI
JUDICIAL v. LEGISLATIVE CHANGE
It is urged by defendants that the decision to replace the doctrine of contributory negligence with the doctrine of comparative negligence must be made by the legislature, not by this court. In each of the States that have judicially adopted comparative negligence, the court addressed the propriety of judicial versus legislative adoption. In each, the court found that contributory negligence is a judicially created doctrine which can be altered or totally replaced by the court which created it. (Scott v. Rizzo (1981), 96 N.M. 682, 686-87, 634 P.2d 1234, 1238-39; Placek v. City of Sterling Heights (1979), 405 Mich. 638, 657, 275 N.W.2d 511, 517, Bradley v. Appalachian Power Co. (W. Va. 1979), 256 S.E.2d 879, 881; Li v. Yellow Cab Co. (1975), 13 Cal. 3d 804, 813-14, 532 P.2d 1226, 1232-33, 119 Cal. Rptr. 858, 864-65; Kaatz v. State (Alaska 1975), 540 P.2d 1037, 1049; Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 434. See Skinner v. Reed-Prentice Division Package Machinery Co. (1978), 70 Ill. 2d 1, 13-14.) Indeed, the United States Supreme Court deemed it appropriate to “ ‘adopt the proportional fault doctrine without Congressional action.’ ” United States v. Reliable Transfer Co. (1975), 421 U.S. 397, 410, 44 L. Ed. 2d 251, 261, 95 S. Ct. 1708, 1715.
The Illinois Defense Counsel has, in its brief, urged that the legislature is better equipped to enact comparative negligence, asserting that “the legislative process *** involves a broad examination of the entire problem without emphasis on a particular fact situation.” The Defense Counsel and defendants claim that judicial adoption of comparative negligence would result in a piecemeal approach that would leave for future cases many ancillary questions. They claim that the law would be left in confusion and turmoil.
An examination of the States from which comparative negligence statutes have emerged reveals that such statutes are very general and brief and do not address collateral issues. Rather, the legislators apparently deemed it wise to leave the solution of collateral issues to the courts. Placek v. City of Sterling Heights (1979), 405 Mich. 638, 658, 275 N.W.2d 511, 518; Kirby v. Larson (1977), 400 Mich. 585, 630, 256 N.W.2d 400, 422; Fleming, Foreword: Comparative Negligence at Last — By Judicial Choice, 64 Cal. L. Rev. 239, 281 (1976); V. Schwartz, Comparative Negligence 360-61 (1974).
Defendants point out that, since 1976, six bills were introduced in the Illinois legislature to abolish the doctrine of contributory negligence (Senate Bill 1674 on April 6, 1976, referred to committee; House Bill 1093, introduced March 29, 1977; House Bill 1368, introduced March 31, 1977; House Bill 1614, introduced April 1, 1977; House Bill 542, introduced February 21, 1979; House Bill 784, introduced March 8, 1979). They interpret the failure of each bill to pass as a sign of the General Assembly’s desire to retain the present status of the rule. Another conclusion may be drawn, however, as pointed out by Mr. Justice Ward in his dissenting opinion in Maki v. Frelk (1968), 40 Ill. 2d 193, 203: See Scott v. Rizzo (1981), 96 N.M. 682, 686-87, 634 P.2d 1234, 1238-39; Kirby v. Larson (1977), 400 Mich. 585, 627-28, 256 N.W.2d 400, 420; Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 438; Fleming, Foreword: Comparative Negligence at Last — By Judicial Choice, 64 Cal. L. Rev. 239, 277 (1976).
“It can be argued that the legislature’s inaction in this area is attributable to its feeling that it is more appropriate, considering the history of the question in Illinois, for the judiciary to act.”
In support of their view that the legislature intends to retain the rule, defendants point to various statutes which have incorporated the contributory negligence defense (Ill. Rev. Stat. 1979, ch. 24, par. 1 — 4—4 (regarding liability for injuries caused by firemen); Ill. Rev. Stat. 1979, ch. 24, pars. 1 — 4—5, 1 — 4—6 (indemnification for injuries caused by policemen); Ill. Rev. Stat. 1979, ch. 34, par. 301.1 (indemnity of sheriff or deputy); Ill. Rev. Stat. 1979, ch. 121, pars. 385, 386 (tort liability of county superintendent of highways); and Ill. Rev. Stat. 1979, ch. 1271/2, par. 46 (liability of firemen for injuries to person or property)). They claim that these statutes act as a legislative ratification of the doctrine of contributory negligence. We do not agree. We believe that in enacting such statutes the legislature did not focus on the merits of the contributory negligence rule, but, rather, conformed the statutes to the then-existing law as announced by the court.
We believe that the proper relationship between the legislature and the court is one of cooperation and assistance in examining and changing the common law to conform with the ever-changing demands of the community. There are, however, times when there exists a mutual state of inaction in which the court awaits action by the legislature and the legislature awaits guidance from the court. Such a stalemate is a manifest injustice to the public. When such a stalemate exists and the legislature has, for whatever reason, failed to act to remedy a gap in the common law that results in injustice, it is the imperative duty of the court to repair that injustice and reform the law to be responsive to the demands of society.
IV
STARE DECISIS
Defendants urge us to abide by the doctrine of stare decisis and follow the holding in Maki v. Frelk (1968), 40 Ill. 2d 193. They contend that it is crucial to the due administration of justice, especially in a court of last resort, that a question once deliberately examined and decided be closed to further scrutiny. It must first be pointed out that the Maki decision, filed 13 years ago, did not, as claimed by defendants, address the merits of the case. On the contrary, the court avoided the merits by holding that the problem was one for the legislature.
It is interesting to observe that if Illinois courts had, in fact, rigidly adhered to the stare decisis rule throughout this State’s legal history, the comparative standard could not have been adopted in Galena & Chicago Union R.R. Co. v. Jacobs (1858), 20 Ill. 478. Similarly, the comparative rule could not have been later discarded in Calumet Iron & Steel Co. v. Martin (1885), 115 Ill. 358, and City of Lanark v. Dougherty (1894), 153 Ill. 163.
The tenets of stare decisis cannot be so rigid as to incapacitate a court in its duty to develop the law. (Molitor v. Kaneland Community Unit District No. 302 (1959), 18 Ill. 2d 11, 26.) Clearly, the need for stability in law must not be allowed to obscure the changing needs of society or to veil the injustice resulting from a doctrine in need of reevaluation. This court can no longer ignore the fact that Illinois is currently out of step with the majority of States and with the common law countries of the world. We cannot continue to ignore the plight of plaintiffs who, because of some negligence on their part, are forced to bear the entire burden of their injuries. Neither can we condone the policy of allowing defendants to totally escape liability for injuries arising from their own negligence on the pretext that another party’s negligence has contributed to such injuries. We therefore hold that in cases involving negligence the common law doctrine of contributory negligence is no longer the law in the State of Illinois, and in those instances where applicable it is replaced by the doctrine of comparative negligence.
V
THE “PURE” VERSUS THE “MODIFIED” FORM OF COMPARATIVE NEGLIGENCE
There remains the question of the form of comparative negligence to be adopted. Under a “pure” form, the plaintiff’s damages are simply reduced by the percentage of fault attributable to him. Under a “modified” form, a negligent plaintiff may recover so long as the percentage of his fault does not exceed 50% of the total.
Defendants argue that should this court decide to adopt comparative negligence, the modified approach should be selected. They point to the basic unfairness of the “pure” system by example: A plaintiff who is 90% negligent has suffered $100,000 in damages. A defendant who is only 10% negligent has suffered only $10,000 in damages. Defendants here point out the basic unfairness of requiring the 10% negligent defendant to pay $10,000 to a plaintiff who was 90% at fault. The United States Supreme Court answered a similar claim concerning liability under admiralty law.
“That a vessel is primarily negligent does not justify its shouldering all responsibility, nor excuse the slightly negligent vessel from bearing any liability at all.” (United States v. Reliable Transfer Co. (1975), 421 U.S. 397, 406, 44 L. Ed. 2d 251, 259, 95 S. Ct. 1708, 1713.)
The liability of a defendant should not depend upon what- damages he sustained but should be determined by the relationship of his fault to the ultimate damages. In a suit under a “pure” form of comparative negligence in which the defendant counterclaims for his own damages, each party must bear the burden of the percentage of damages of all parties in direct proportion to his fault. In the example above, the 90% negligent plaintiff will bear 90% of his own damages as well as 90% of defendant’s. On the other hand, the 10% negligent defendant will be made to bear 10% of his own damages as well as 10% of plaintiff’s. Neither party is unjustly enriched. Neither party escapes liability resulting from his negligent acts or omissions. It is difficult to see unfairness in such a distribution of liability. See Hoffman v. Jones (Fla. 1973), 280 So. 2d 431, 439; Scott v. Rizzo (1981), 96 N.M. 682, 689-90, 634 P.2d 1234, 1241-42; V. Schwartz, Comparative Negligence 345 (1974).
Opponents of the “pure” form of comparative negligence claim that the “modified” form is superior in that it will increase the likelihood of settlement and will keep down insurance costs. However, studies done comparing the effects of the “pure” versus the “modified” forms show the differences in insurance rates to be inconsequential. (V. Schwartz, Comparative Negligence 346 (1974).) Fears as to the likelihood of settlement are not supported in fact or logic. It is argued that the negligent plaintiff will refuse to settle knowing that, under the “pure” system he will be able to recover “something” in court. The converse can as easily apply: the defendant may be encouraged to settle knowing that he cannot rely on the “modified” 50% cut-off point to relieve him of liability. A comparison of results under both the “pure” and “modified” forms showed that in Arkansas there was only a slight decrease in number of settlements when the State changed from “pure” to “modified.” Rosenberg, Comparative Negligence in Arkansas: A “Before and After” Survey, 13 Ark. L. Rev. 89 (1959).
Wisconsin’s “modified” system has been criticized because a large number of cases appealed focused on the narrow question of whether plaintiff’s negligence amounted to 50% or less of the aggregate. (Prosser, Comparative Negligence, 41 Cal. L. Rev. 1, 23 (1953).) This, in fact, caused the Wisconsin Supreme Court to examine the question of whether the “modified” system should be replaced with the “pure” form of comparative negligence. (Vincent v. Pabst Brewing Co. (1970), 47 Wis. 2d 120, 177 N.W.2d 513.) There, as in Maki v. Frelk (1968), 40 Ill. 2d 193, the merits of the case were not addressed, for the majority of the court ruled that the determination should be left to the legislature, which had originally adopted the “modified” form by statute. One dissenting and three concurring justices, however, expressed their intent to judicially adopt the “pure” form if the legislature failed to do so. See Li v. Yellow Cab Co. (1975), 13 Cal. 3d 804, 829, 532 P.2d 1226, 1243, 119 Cal. Rptr. 858, 875; Placek v. City of Sterling Heights (1979), 405 Mich. 638, 660-61, 375 N.W.2d 511, 519; Kirby v. Larson (1977), 400 Mich. 585, 642-44, 256 N.W.2d 400, 428.
The “pure” form of comparative negligence is the only system which truly apportions damages according to the relative fault of the parties and, thus, achieves total justice. We agree with the Li court that “the ‘50 percent’ system simply shifts the lottery aspect of the contributory negligence rule to a different ground.” (Li v. Yellow Cab Co. (1975), 13 Cal. 3d 804, 827, 532 P.2d 1226, 1242, 119 Cal. Rptr. 858, 874.) There is no better justification for allowing a defendant who is 49% at fault to completely escape liability than there is to allow a defendant who is 99% at fault under the old rule to escape liability.
Mindful of the facts stated and that the vast majority of legal scholars who have studied the area recommend the “pure” approach, we are persuaded that the “pure” form of comparative negligence is preferable, and we therefore adopt it as the law of Illinois.
The collateral issue of contribution among joint tortfeasors has already been resolved under the principles of comparative negligence in Skinner v. Reed-Prentice Division Package Machinery Co. (1978), 70 Ill. 2d 1, 14, wherein this court found that “governing equitable principles require that ultimate liability for plaintiff’s injuries be apportioned on the basis of the relative degree to which [each defendant’s] conduct proximately caused them.” (See also Ill. Rev. Stat. 1979, ch. 70, par. 301 et seq.) We have already noted that the doctrine of “last clear chance” was created to escape the harshness of the contributory negligence rule. As the need for it disappears in the face of this decision, the vestiges of the doctrine of “last clear chance” are hereby abolished.
We believe that the use of special verdicts and special interrogatories will serve as a guide to assist the jury in its deliberations. We leave the resolution of other collateral issues to future cases.
VI
APPLICATION
Finally, we address the question of the applicability of the rule here announced. We hold that this opinion shall be applied to the parties before us on appeal and to all cases in which trial commences on or after June 8, 1981, the date on which the mandate in this case shall issue. This opinion shall not be applicable to any case in which trial commenced before that date — except that if any judgment be reversed on appeal for other reasons, this opinion shall be applicable to any retrial.
For the reasons stated, we hereby abolish the common law doctrine of contributory negligence and adopt in its place the doctrine of comparative negligence in its pure form. The judgments of the appellate court and circuit courts are reversed and the causes are remanded to the respective circuit courts for further proceedings in accordance with the views expressed herein.
Reversed and remanded.
