delivered the opinion of the court:
Clifford M. Jasper died as a result of injuries sustained on January 24, 1978, whñe operating a hydraulic aerial work platform manufactured by defendant, J. L. G. Industries, Inc. Plaintiff, Jack A. Coney, administrator of Jasper’s estate, filed a two-count complaint in the circuit court of Peoria County under the wrongful death and survival acts (Ill. Rev. Stat. 1977, ch. 70, par. 1 et seq., ch.1 IIOV2, par. 27 — 6) based on a strict products liability theory. Defendant filed two affirmative defenses. The first asserted that Jasper was guilty of comparative negligence or fault in his operation of the platform. The second contended that Jasper’s employer, V. Jobst & Sons, Inc., was also guilty of comparative negligence in failing to instruct and train Jasper on the operation of the platform and by failing to provide a “groundman.” In these defenses, defendant requested that its fault, if any, be compared to the total fault of all parties and any judgment against defendant reflect only its percentage of the overall liability, i.e., that defendant not be held jointly and severally liable.
On plaintiff’s motion, the trial court struck the defenses, but it certified three questions for appeal pursuant to Supreme Court Rule 308 (73 Ill. 2d R. 308). In an unpublished order, the appellate court denied defendant’s application for leave to appeal, indicating the short record supplied did not provide sufficient facts to allow proper consideration of the policy questions involved. We allowed defendant leave to appeal.
The three certified questions are:
“Whether the doctrine of comparative negligence or fault is applicable to actions or claims seeking recovery-under products liability or strict liability in tort theories?
Whether the doctrine of comparative negligence or fault eliminates joint and several liability?
Whether the retention of joint and several liability in a system of comparative negligence or fault denies defendants equal protection of the laws in violation of U.S. Const. Amend. XIV, §1 and Ill. Const. 1970, §2 as to causes of action arising on or after [sic] March 1, 1978. (Ill. Rev. Stat. 1979, ch.70, §301 et seq.)T’

COMPARATIVE FAULT AND STRICT LIABILITY
In Suvada v. White Motor Co. (1965),
“(1) One who sells any product in a defective condition unreasonably dangerous to the user or consumer or to his property is subject to liability for physical harm thereby caused to the ultimate user or consumer, or to his property, if
(a) the seller is engaged in the business of selling such a product, and
(b) it is expected to and does reach the user or consumer without substantial change in the condition in which it is sold.
(2) The rule stated in Subsection (1) applies although
(a) the seller has exercised all possible care in the preparation and sale of his product, and
(b) the user or consumer has not bought the product from or entered into any contractual relation with the seller.”
In adopting strict liability in tort, this court said:
“[P]ublic interest in human life and health, the invitations and solicitations to purchase the product and the justice of imposing the loss on the one creating the risk and reaping the profit are present and as compelling in cases involving motor vehicles and other products, where the defective condition makes them unreasonably dangerous to the user, as they are in food cases.”32 Ill. 2d 612 , 619.
But imposition of strict liability was not meant to make the manufacturer an absolute insurer. (Liberty Mutual Insurance Co. v. Williams Machine & Tool Co. (1975),
Traditionally in negligence actions, however, any contributory negligence by the plaintiff was an absolute defense which barred recovery. (Mueller v. Sangamo Construction Co. (1975),
In the instant case, defendant argues that Alvis requires the adoption of a comparative fault system in strict products liability cases. Defendant maintains “total justice” can only be achieved where the relative fault of all the parties is considered in apportioning damages. To illustrate its argument, defendant points to the anomalous situation where, in a single case with alternate counts of negligence and strict liability, the identical conduct by the plaintiff which amounts to an assumption of the risk will completely bar recovery in the strict liability count, yet, as a result of Alvis, will only reduce his award under the negligence count. Moreover, if the plaintiff is only contributorily negligent, he recovers all his damages under strict liability, but his recovery is diminished under the negligence count. Defendant argues that common sense mandates an approach which is consistent in its treatment of all the parties to an action, whether founded on common law negligence or strict liability.
We are not the first to consider the impact of comparative negligence upon strict liability. Some jurisdictions have declined to apply comparative negligence or fault principles in strict liability actions:
Colorado Kinard v. Coats Co. (1976),
Nebraska Melia v. Ford Motor Co. (8th Cir. 1976),
Oklahoma Kirkland v. General Motors Corp. (Okla. 1974),
Rhode Island Roy v. Star Chopper Co. (1st Cir. 1978),
South Dakota Smith v. Smith (S.D. 1979),
The vast majority, though, have found comparative negligence theory applicable in strict liability cases.

Arkansas Ark. Stat. Ann. secs. 27—1763 to 27—1765 (1979).

Wisconsin Dippel v. Sciano (1967),
In the case at bar, plaintiff argues that applying comparative fault principles in strict liability actions would raise the conduct of the product user to a position equal to that of the manufacturer in regard to the prevention of injury; and that it would thereby give undue advantage to the manufacturer. The Illinois Trial Lawyers Association, in their amicus curiae brief, assert that comparative fault applied in this instance would undermine the policy basis that led to the imposition of strict liability. Further, they argue that reducing a plaintiff’s recovery according to his fault would lessen the manufacturer’s incentive to design and market a defect-free, safe product. As authority for their position, plaintiff and amicus curiae rely primarily on Smith v. Smith (S.D. 1979),
In Smith v. Smith (S.D. 1979),
In Kinard v. Coats Co. (1976),
Similarly, the court in Seay v. Chrysler Corp. (1980),
We believe that application of comparative fault principles in strict products liability actions would not frustrate this court’s fundamental reasons for adopting strict products liability as set out in Suvada. The plaintiff will still be relieved of the proof problems associated with negligence and warranty actions. Privity and a manufacturer’s negligence continue to be irrelevant. Nor would comparative fault lessen the manufacturer’s duty to produce reasonably safe products. The manufacturer’s liability remains strict; only its responsibility for damages is lessened by the extent the trier of fact finds the consumer’s conduct contributed to the injuries. Daly v. General Motors Corp. (1978),
Further, the risk associated with the product defect is still spread among all consumers. Only that portion due to plaintiff’s own conduct or fault is borne by the plaintiff. Where the allocation of losses properly can be apportioned, we see no reason to spread the cost of the loss resulting from plaintiff’s own fault on to the consuming public. See Daly v. General Motors Corp. (1978),
Plaintiff and amicus curiae next argue that the comparison of the plaintiff’s fault with the defendant’s defective product is a comparison of noncomparables, an attempt to compare “apples and oranges,” and that this comparison cannot be applied logically and consistently in strict products liability cases. See Daly v. General Motors Corp. (1978),
Although it appears theoretically difficult to balance the defendant’s strict liability against the user’s negligence, other courts and their juries have been able to do so. In this regard, Professor Schwartz said:
“It is true that the jury might have some difficulty in making the calculation required under comparative negligence when defendant’s responsibility is based on strict liability. Nevertheless, this obstacle is more conceptual than practical. The jury should always be capable, when the plaintiff has been objectively at fault, of taking into account how much bearing that fault had on the amount of damage suffered and of adjusting and reducing the award accordingly. Triers of fact are apparently able to do this, and the benefits from the approach suggest that it be applied in all comparative negligence jurisdictions.” V. Schwartz, Comparative Negligence sec. 12.7, at 208-09 (1974).
A manufacturer is under a nondelegable duty to produce a product which is reasonably safe. (Anderson v. Hyster Co. (1979),
The court in Murray v. Fairbanks Morse (3d Cir. 1979),
In Skinner v. Reed-Prentice Division Package Machinery Co. (1977),
Similarly, we believe that equitable principles require that the total damages for plaintiff’s injuries be apportioned on the basis of the relative degree to which the defective product and plaintiff’s conduct proximately caused them. Accordingly, we hold that the defense of comparative fault is applicable to strict liability cases.
Amicus curiae argues that, if comparative fault is to be applied in strict products liability cases, we should not reduce a plaintiff’s award if he merely fails to “inspect,” “discover,” or “guard against” a defective product. Butaud v. Suburban Marine & Sporting Goods, Inc. (Alaska 1976),
Following the Restatement, this court, in Williams v. Brown Manufacturing Co. (1970),
However, the defenses of misuse and assumption of the risk will no longer bar recovery. Instead, such misconduct will be compared in the apportionment of damages. Specifically, we hold: Once defendant’s liability is established, and where both the defective product and plaintiff’s misconduct contribute to cause the damages, the comparative fault principle will operate to reduce plaintiff’s recovery by that amount which the trier of fact finds him at fault.
Thus, the defendant remains strictly hable for the harm caused by its defective product, except for that part caused by the consumer’s own misconduct.
n
JOINT AND SEVERAL LIABILITY
The common law doctrine of joint and several liability holds joint tortfeasors responsible for the plaintiff’s entire injury, allowing plaintiff to pursue all, some, or one of the tortfeasors responsible for his injury for the full amount of the damages. Paul Harris Furniture Co. v. Morse (1956),
Defendant asserts joint and several liability is a corollary of the contributory negligence doctrine. Prior to Alvis, a plaintiff who was guilty of even slight contributory negligence was barred from recovery. Defendant maintains that joint and several liability balanced this inequity by permitting a faultless plaintiff to collect his entire judgment from any defendant who was guilty of even slight negligence. With the adoption of comparative negligence where dam,ages are apportioned according to each party’s fault, defendant argues it is no longer rational to hold a defendant liable beyond his share of the total damages. Defendant relies primarily on a line of cases where joint and several liability was abolished or limited in the course of construing a statutory scheme of liability. Brown v. Keill (1978),
The vast majority of jurisdictions, however, which have adopted comparative negligence have retained joint and several liability as a part of their comparative negligence doctrine:
Alaska Arctic Structures, Inc. v. Wedmore (Alaska 1979),
Arkansas Ark. Stat. Ann. secs. 34—1001 to 34—1009 (1981).
California American Motorcycle Association v. Superior Court (1978),
Colorado Colo. Rev. Stat. sec. 13—50.5—103 (1977).
Connecticut Conn. Gen. Stat. Ann. sec. 52—572o (Supp. 1982).
Florida Lincenberg v. Issen (Fla. 1975),
Georgia Gazaway v. Nicholson (1940),
Idaho Tucker v. Union Oil Co. (1979),
Maine Me. Rev. Stat. tit. 14, sec. 156 (1965).
Michigan Conkright v. Ballantyne of Omaha, Inc. (W.D. Mich. 1980),
Minnesota Maday v. Yellow Taxi Co. (Minn. 1981),
Nebraska Royal Indemnity Co. v. Aetna Casualty & Surety Co. (1975),
New Jersey N.J. Stat. Ann. sec. 2A: 15—5.1 (Supp. 1982).
New York Kelly v. Long Island Lighting Co. (1972),
North Dakota N.D. Cent. Code sec. 9—10—07 (1973).
Washington Wash. Rev. Code Ann. sec. 4.22.030 (Supp. 1982).
Wisconsin Wisconsin Natural Gas Co. v. Ford, Bacon & Davis Construction Corp. (1980),
Generally, four reasons have been advanced for retaining joint and several liability:
(1) The feasibility of apportioning fault on a comparative basis does not render an indivisible injury “divisible” for purposes of the joint and several liability rule. A concurrent tortfeasor is liable for the whole of an indivisible injury when his negligence is a proximate cause of that damage. In many instances, the negligence of a concurrent tortfeasor may be sufficient by itself to cause the entire loss. The mere fact that it may be possible to assign some percentage figure to the relative culpability of one negligent defendant as compared to another does not in any way suggest that each defendant’s negligence is not a proximate cause of the entire indivisible injury.
(2) In those instances where the plaintiff is not guilty of negligence, he would be forced to bear a portion of the loss should one of the tortfeasors prove financially unable to satisfy his share of the damages.
(3) Even in cases where a plaintiff is partially at fault, his culpability is not equivalent to that of a defendant. The plaintiff’s negligence relates only to a lack of due care for his own safety while the defendant’s negligence relates to a lack of due care for the safety of others; the latter is tortious, but the former is not.
(4) Elimination of joint and several liability would work a serious and unwarranted deleterious effect on the ability of an injured plaintiff to obtain adequate compensation for his injuries. American Motorcycle Association v. Superior Court (1978),20 Cal. 3d 578 ,578 P.2d 899 ,146 Cal. Rptr. 182 . See Arctic Structures, Inc. v. Wedmore (Alaska 1979),605 P.2d 426 ; Tucker v. Union Oil Co. (1979),100 Idaho 590 ,603 P.2d 156 ; Seattle First National Bank v. Shoreline Concrete Co. (1978),91 Wash. 2d 230 ,588 P.2d 1308 . See also Wisconsin Natural Gas Co. v. Ford, Bacon & Davis Construction Corp. (1980),96 Wis. 2d 314 ,291 N.W.2d 825 .
In adopting comparative negligence, this court eliminated the total bar to recovery which a plaintiff had faced under contributory negligence. In return for allowing a negligent plaintiff to recover, this court said fairness requires that a plaintiff’s damages be “reduced by the percentage of fault attributable to him.” (Emphasis added.) (Alvis v. Ribar (1981),
Further support for retaining joint and several liability is found in “An Act in relation to contribution among joint tortfeasors” (Act) (Ill. Rev. Stat. 1979, ch. 70, par. 301 et seq.). Although the instant case accrued prior to its effective date, the Act expresses the intent of our legislature concerning joint and several liability:
“Sec. 4. Rights of Plaintiff Unaffected. A plaintiff’s right to recover the' full amount of his judgment from any one or more defendants subject to liability in tort for the same injury to person or property, or for wrongful death, is not affected by the provisions of this Act.” Ill. Rev. Stat. 1979, ch. 70, par. 304.
Moreover, under the Act, it is the defendant or defendants who must bear the burden of the insolvent or immune defendant:
“Sec. 3. Amount of Contribution. The pro rata share of each tortfeasor shall be determined in accordance with his relative culpability. However, no person shall be required to contribute to one seeking contribution an amount greater than his pro rata share unless the obligation of one or more of the joint tortfeasors is uncollectible. In that event, the remaining tortfeasors shall share the unpaid portions of the uncollectible obligation in accordance with their pro rata liability.
If equity requires, the collective liability of some as a group shall constitute a single share.” 111. Rev. Stat. 1979, ch. 70, par. 303.
Defendant concedes that where the plaintiff is free from fault each defendant should still be held jointly and severally liable. It also admits in its reply brief that the Act leaves unaffected the common law doctrine of joint and several liability. Defendant points out, however, that it was subsequent to the enactment of the Act that this court adopted comparative negligence. Now, under Alvis, damages are allocated according to fault. As such, defendant argues, Alvis mandates that a tortfeasor should be liable only to the extent that his negligent acts or omissions produced the damages.
We find nothing in Alvis which mandates either a shift in who shall bear the risk of the insolvent defendant or the elimination of joint and several liability. Defendant has not cited nor have we found persuasive judicial authority for the proposition that comparative negligence compels the abolition of joint and several liability. On the contrary, most jurisdictions which have adopted comparative negligence have retained the doctrine. Therefore, we hold that our adoption of comparative negligence in Alvis does not change the long-standing doctrine of joint and several liability.
ill
EQUAL PROTECTION
Initially, defendant notes that contribution in strict liability actions may be sought from joint tortfeasors only for causes of action arising out of occurrences on or after March 1, 1978 (Ill. Rev. Stat. 1979, ch. 70, par. 301; Skinner v. Reed-Prentice Division Package Machinery Co. (1977),
Basically, defendant’s argument is directed toward the prospective application of Skinner, wherein the court set forth a new rule of law in strict liability cases. Since the rule was not applied retroactively, so as to include the instant case, defendant reasons it was denied equal protection under the law. Based upon this premise, it argues joint and several liability should be abrogated in cases where comparative fault principles control. We find defendant’s argument to be without merit.
Prospective application of a new doctrine or rule of law does not violate the equal protection of laws under either the Federal or Illinois constitution. (See Great Northern Ry. Co. v. Sunburst Oil & Refining Co. (1932),
Further, we question defendant’s standing to raise its constitutional objections in the instant case, where it seeks to apply the holding in Skinner. There, the court had before it a third-party complaint by the manufacturer against the employer setting forth a cause of action for contribution. Here, however, defendant has not filed a third-party complaint. Instead, by way of defense, it attempts to classify the employer as a joint tortfeasor and have the employer’s negligence compared even though it was not joined as a party. In this manner, defendant attempts to circumvent the prospective rule established in Skinner which was codified in “An Act in relation to contribution among joint tortfeasors.” This it cannot do. See Buehler v. Whalen (1977),
The doctrine of joint and several liability like contribution, operates only where two or more persons are subject to liability in tort arising out of the same injury to a plaintiff. (See Ill. Rev. Stat. 1979, ch. 70, par. 302; Paul Harris Furniture Co. v. Morse (1956),
Therefore, in response to the questions posed, we conclude that (1) comparative fault is applicable to strict products liability actions; (2) comparative fault does not eliminate joint and several liability; and (3) retention of joint and several liability does not deny defendants equal protection of the laws.
The order of the circuit court striking the affirmative defenses is affirmed, and the cause is remanded to the circuit court of Peoria County with directions to allow defendant to amend his first defense so as to be consistent with the views expressed herein.
Affirmed and remanded, with directions.
