*1057
negligence statute, section 13-21-111, C.R. S.1973 & 1982 Supp., and the Uniform Contribution Among Tortfeasors Act, sections 13-50.5-101 to 106, C.R.S.1973 (1982 Supp.). In
National Farmers Union Property & Casualty Co. v. Frackelton,
I.
In 1976, William Frackelton and Robert Kerr suffered severe electrical burns while working at a job site near Telluride, Colorado. Frackelton and Kerr, who worked for different employers, were inserting a cable into a conduit attached to a power pole. A cap had been removed from the end of the conduit. As the two men pushed the cable up the conduit it came into contact with the power lines on top because of the absence of the cap, causing electroshock injuries. San Miguel Power Association (San Miguel) was responsible for maintaining the power poles and lines and was also in charge of supervising the work in which Kerr and Frackel-ton were engaged.
Frackelton and Kerr individually asserted claims for negligence against San Miguel for the injuries which they suffered. The district court consolidated both claims for trial, C.R.C.P. 42, because of the similarity of factual and legal issues. Frackelton, however, was never joined as a party in the Kerr case and Kerr was not a party in the Frackelton case. San Miguel, which originally filed a counterclaim alleging that Frackelton was responsible for Kerr’s injuries, dropped the counterclaim before trial.
During the trial, Frackelton presented his case as a plaintiff seeking damages in negligence from a sole defendant. In neither case did San Miguel or Kerr assert that Frackelton was jointly responsible for Kerr’s injuries, and San Miguel did not seek contribution from Frackelton as a joint tortfeasor. Nevertheless, the trial court, on its own motion, instructed the jury to make a comparison of Frackelton’s and San Miguel’s negligence in the Kerr suit.
The jury returned a verdict in the Kerr suit finding Kerr 10% negligent, Frackelton 35% negligent, and San Miguel 55% negligent in causing Kerr’s injuries. The jury awarded $690,000 in damages to Kerr, which was reduced by 10% to $621,000. In the Frackelton suit, the jury found Frackel-ton 38% negligent and San Miguel 62% negligent, and awarded Frackelton $475,000, which was reduced by 38% to $294,500. The only issues to be resolved in the Frackelton ease were damages for the injuries suffered by Frackelton and the comparative fault of the parties.
The petitioner, National Farmers Union Property and Casualty Co. (NFU), was San Miguel’s liability insurer. NFU paid Kerr’s judgment in full and then commenced a declaratory judgment action seeking contribution from Frackelton. In the declaratory judgment action, NFU sought a reduction in the amount it owed Frackelton. NFU asked for a set-off against the amount it owed Frackelton by the amount paid Kerr above its pro rata share of negligence determined in the prior action. NFU based its action on the jury’s findings of relative fault in the Kerr suit among Kerr, Frackel-ton, and San Miguel.
The district court entered summary judgment in the declaratory judgment action in favor of NFU, finding that Frackelton was bound by the jury’s allocation of fault in the Kerr lawsuit. Thus, the court ordered Frackelton to offset $293,800 1 (the amount Frackelton would have owed Kerr) against *1058 the $294,500 judgment (sixty-two percent of $475,000) he had obtained from San Miguel.
The court of appeals reversed the summary judgment. The court held that Frackel-ton was not bound by the jury’s finding of liability in the
Kerr v. San Miguel
lawsuit because Frackelton was not a “party” to that claim for relief. Since no judgment was entered against Frackelton vis-a-vis Kerr, the court reasoned 'that the issue of comparative negligence was not settled among Frackelton, Kerr, and San Miguel. The court of appeals, interpreting the contribution act, also held that contribution “applies only to parties against whom a judgment of liability has been entered, but not necessarily recovered”; and that “the judgment of liability of the several defendants must be entered before it is binding among such defendants in determining their right to contribution.”
II.
A. Multiple Parties
There is no doubt that multiple party issues under the comparative negligence statute and the contribution act are extremely complex legal issues. The confusing interrelationships among issues of joint negligence, settlement, indemnification, and contribution cast some doubts on the efficacy of legislation designed to resolve fairly issues of relative fault and liability. See McNichols, Judicial Elimination of Joint and Several Liability Because of Comparative Negligence — A Puzzling Choice, 32 Okla.L.Rev. 1, 37-38 (1979).
The comparative negligence statute, section 13-21-111, C.R.S.1973 & 1982 Supp., was intended to ameliorate the harsh common law rule which barred a contributorily negligent plaintiff from any recovery.
Mountain Mobile Mix v. Gifford,
The much-needed torts legislation, however, left many unanswered questions. The first and most fundamental question is: To whom do the statutes apply?
The court of appeals held that Frackelton was not a “party” to Kerr’s lawsuit against San Miguel in the determination of comparative negligence for the purpose of resolving companion issues of contribution. The court found that Frackelton had never been joined as a co-plaintiff or co-defendant in Kerr’s lawsuit nor had any claims or counterclaims been asserted against Frackelton by the original parties. The court reasoned that language in the comparative negligence statute 2 “contemplates that the comparison of negligence be made only between parties [of record] to the tort action.” 650 *1059 P.2d at 572. Similarly, the court read the contribution act to apply only to “parties against whom a judgment of liability has been entered, but not necessarily recovered.” Id. (emphasis added). 3 We agree in part with the court of appeals’ conclusions.
B. Absent Tortfeasors
Before we discuss Frackelton’s status in NFU’s declaratory judgment action, we must determine whether the district court was correct in submitting the issue of Frackelton’s negligence for the jury’s consideration. We conclude that the comparative negligence statute precludes consideration of the negligence of absent tortfeasors by the trier of fact. In determining factual issues only the negligence of the parties to the lawsuit who participate in the trial should be considered in resolving liability under the comparative negligence statute.
The purpose of comparative negligence is to apportion negligence among those who caused the harm. Mountain Mobile Mix v. Gifford, supra. Ideally, the plaintiff and defendant will seek to join every potentially culpable party, either to increase the number of tortfeasors from whom damages can be recovered or to spread liability among multiple tortfeasors. Rules of joint and several liability insure that plaintiffs will recover fully, while the contribution act insures that defendants will pay only their percentage share of liability.
The problem of how to deal with those potentially culpable persons who cannot be brought into a lawsuit is difficult to resolve. Often, through no fault of either the plaintiff or the defendant, jurisdiction over a tortfeasor cannot be obtained, or a statutory or common law immunity may preclude joinder of some potentially culpable individuals. Were we developing a common law of comparative negligence we might reach a different result; our reading of existing statutes and case law, however, convinces us that the negligence of absent tortfeasors should not be considered by the trier of fact.
Policy considerations do not weigh heavily in favor of either position on the absent tortfeasor issue. The most compelling reason to consider the negligence of absent tortfeasors is that a more accurate allocation of negligence will result.
See Pierringer v. Hoger,
A second argument supporting consideration of absent tortfeasors is that it would tend to insure that all claims will be determined in one lawsuit. A full comparison in the original suit encourages plaintiffs to *1060 join all potential tortfeasors in a single lawsuit. Paul v. N.L. Industries, Inc., supra. Similarly, joint and several liability and contribution encourage the defendant to join all potential joint tortfeasors. Many issues in multiple party suits can thereby be resolved in a single forum, thus avoiding unnecessary litigation.
Full comparison may also tend to encourage settlement before trial. Plaintiffs and defendants may not wish to litigate because of the effect on the jury of the unknown factor of absent tortfeasors. Defendants in particular may not wish to risk joint and several liability for the plaintiff’s losses with slight hopes of recovering contribution from difficult-to-locate joint tortfeasors. Paul v. N.L. Industries, Inc., supra.
These considerations, however, must be balanced against competing policy arguments. First, a comparison of the negligence of absent tortfeasors may work to defeat any recovery by a deserving plaintiff. Under our comparative negligence statute, the plaintiff may satisfy the judgment awarded only from those tortfeasors whose combined negligence is greater than the plaintiffs and “against whom recovery is sought.” Section 13-21-111, C.R.S.1973. The persons against whom recovery is sought are defendant-tortfeasors and any third party defendant who participate in the trial. A defendant who has settled with the plaintiff is not a person “against whom recovery is sought.” Likewise, the plaintiff’s claim against tortfeasors named as defendants should not be compromised in cases where the identity of an absent tort-feasors is unknown, such as the “phantom” in a three car hit-and-run accident. By requiring the jury to apportion 100 percent of the negligence among the parties, the burden of persuading the factfinder to resolve the comparative negligence equation is shared equally between the plaintiffs and the tortfeasors who participate in the trial.
Second, it is unfair to saddle the plaintiff with the burden of litigating liability issues of a non-party or to try the absent tort-feasor
in absentia
under conditions which could not bind that person under principles of res judicata or collateral estoppel.
See Shanley v. Callanan Industries, Inc.,
Third, the contribution among tortfeasors act preserves the right of the named defendants to sue other joint tortfeasors to correct overpayments to the plaintiff. A plaintiff has every incentive to join all potential tortfeasors because of our joint and several liability and combined comparison rules; however, it is preferable to place the burden of finding and suing absent tort-feasors on those who caused plaintiff to suffer damages.
These competing arguments create difficult policy choices, none of which is clearly superior to the other. Our reading of the language in the comparative negligence statute, however, convinces us that comparison of the negligence of named parties who participate in the trial is the choice made by the General Assembly.
Section 13-21-111(1) directs the trier of fact to reduce the recovery of contributorily negligent plaintiffs by their percentage of negligence. The comparison is made against the person or persons “against whom recovery is sought.” 4 See Mountain Mobile Mix v. Gifford, supra (the negligence of all party defendants is combined in *1061 comparison to plaintiff’s negligence). Section 13-21-lll(2)(b) instructs the trier of fact to return a special verdict stating the “degree of negligence of each party,” Section 13-21-111(4) requires the trial court to instruct the jury on the effect of a determination of comparative negligence on “each party” and that the “attorneys for each party” may argue the effect of comparative negligence before the jury.
We believe that the plain and natural meaning of the statutory language precludes us from expanding the statute to include consideration of absent tortfeasors. The word “party” has been previously interpreted by this court to mean a person who has appeared in the litigation and who is described in the record as a plaintiff or defendant.
See, e.g., Wise v. Turner,
Our conclusion is bolstered by the General Assembly’s recent legislation applying comparative negligence to products liability cases. In section 13-21-406, C.R.S.1973 (1982 Supp.), the General Assembly explicitly stated that in products liability cases comparative fault should be considered only among all “parties to the action.” In our view, section 13-21-111 should be interpreted consistent with that language. Further modifications of the comparative negligence act to include consideration of absent tort-feasors should be left to the General Assembly. Accordingly, we affirm the holding of the court of appeals on this issue.
C. Subsequent Action for Contribution
The district court ruled in the subsequent declaratory judgment action for contribution by NFU against Frackelton that the jury’s findings of percentage fault were binding on Frackelton. The court then entered summary judgment for NFU with a corresponding set-off of the amount which NFU paid Kerr above its pro rata share of 55% in the original negligence action (to which Frackelton was never a named party) where fault was allocated among Kerr (10%), Frackelton (35%), and San Miguel (55%). We cannot agree with the district court that Frackelton was bound in a separate declaratory judgment action by the jury’s determination of negligence in a suit to which he was never joined as a party.
As the court of appeals pointed out, the trial court’s discretionary order of consolidation does not merge the consolidated suits into a single cause of action.
It is axiomatic that a person must have notice that a claim is being asserted against him. Frackelton’s litigative approach to the Kerr lawsuit might have changed drastically if he knew that he was considered a party for the purposes of a subsequent contribution action. First, Frackelton believed he was suing only San Miguel and defending only against the defense of contributory negligence. Since Kerr had not sued Frackelton, nor had San Miguel impleaded him, Frackelton had no reason to contest Kerr’s contributory negligence in hopes of reducing Kerr’s recovery and enhancing his own. Second, Frackelton may have considered settling with Kerr if he knew that the jury’s findings in the Kerr suit would be binding. Third, because Frackelton and Kerr were represented by the same attorneys, a conflict of interest arises if the plaintiffs are considered opposing parties in the same action because both parties would want to place a higher degree of fault on the other party. See, e.g., Code of Professional Responsibility D.R. 5-105 (1973). In our view, these considerations weigh heavily against considering Frackelton bound by the jury’s findings.
Issues of res judicata and collateral estoppel are also raised by the trial court’s ruling. The declaratory judgment, in effect, enforces a judgment against someone not a party to the previous suit. Collateral estoppel cannot be applied to the disadvantage of a person who has not litigated the issue in question:
“Some litigants — those who have never appeared in a prior action — may not be collaterally estopped without litigating the issue. They have never had the chance to present their evidence and arguments on the claim. Due process prohibits estopping them despite one or more existing adjudications of the identical issue which stand squarely against their position.”
Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation,
*1063
It was error for the trial court to bind Frackelton in a declaratory judgment action to the jury’s findings of relative fault in the prior action to which he was not a party.
See Eurich v. Alkire,
D. Contribution From a Non-Party
The court of appeals held that an insurer of a tortfeasor found liable in a prior action could not recover contribution from a non-party to that prior action. We disagree.
An important aspect of the contribution act is that contribution can be sought from tortfeasors not joined in the prior action. It is only necessary that “two or more persons become jointly or severally
liable in tort
for the same injury to person or property .... even though judgment has not been recovered against all or any of them.” Section 13-50.5-102(1) (emphasis added). Thus, a person “liable in tort,” but not a party to the original suit may still be liable for contribution. The language “liable in tort” in section 13-50.5-102(1) refers to a person’s exposure to a civil action
6
and not to the existence of final judgment in tort.
See Tamashiro v. DeGama,
Furthermore, section 13-50.5-102(5) expressly allows insurers to seek contribution. 7 Almost by necessity, an insurer will not be able to assert its contribution claim until after the “prior action” has concluded. The court of appeals’ reading of the statute would make the line-up of parties in the initial lawsuit almost conclusive for the purposes of later contribution actions.
The court of appeals also held that an entry of judgment is necessary before the right of contribution accrues. As stated above, the statute only requires that a person become “liable in tort” before the right of contribution arises. The right to collect contribution, of course, depends on a binding and final determination of fault among joint tortfeasors. That judgment may be obtained in the initial lawsuit by asserting a claim of contribution or in a separate action. Sections 13-50.5-104(1) & (2).
*1064 III.
The interrelationship between comparative negligence and contribution among tortfeasors raises many difficult issues, especially when the number of parties involved in a suit increases. Fortunately, most theoretical multiple party problems can be resolved simply by joinder of potential tortfeasors and resolution of contribution issues in the initial cause of action. For example, in this case San Miguel could have prevented the ensuing controversy by impleading Frackelton as a third-party defendant.
For the reasons discussed above, we affirm the judgment of the court of appeals. The district court’s summary judgment is reversed and on remand the petitioner should be permitted to amend its complaint to bring an action for contribution consistent with section II, D of this opinion.
