Texas Industries, Inc., the defendant in a civil antitrust action, appeals the dismissal of its third-party complaint impleading its alleged coconspirators and seeking contribution. The sole issue is whether a right of contribution is available to an antitrust defendant under the federal antitrust laws. We hold that there is no such right of contribution.

This action was instituted on September 8, 1975, by Wilson P. Abraham Construction Corp., not a party to this appeal, against Texas Industries, Inc.1 for damages arising out of an alleged price-fixing scheme. Abraham's complaint asserts that Texas Industries and certain unnamed coconspirators engaged in an unlawful combination and conspiracy to raise and stabilize the price of ready-mix concrete in the New Orleans area in violation of Section 1 of the Sherman Act, 15 U.S.C. § 1.2 Abraham seeks to recover treble damages under 15 U.S.C. § 15.

Discovery instituted by Texas Industries revealed that the unnamed alleged coconspirators were Radcliff Materials, Inc., Jimco, Inc., and OKC Dredging, Inc. Texas Industries then filed a third-party complaint against these parties seeking contribution from them should it be found liable to Abraham in the main demand. The third-party defendants filed motions to dismiss the third-party complaint pursuant to Rule 12(b)(6) for failure to state a claim upon which relief could be granted.

On October 4, 1977, the district court entered a Minute Entry granting the motions to dismiss the third-party complaint with prejudice on the ground that no right of contribution exists among antitrust coconspirators under federal law. Although persuaded by Texas Industries' arguments in favor of allowing contribution, the court deferred to what it considered the "weight of authority"3 denying such a right to an antitrust defendant. On March 29, 1978, the court determined that there was no just reason for delay and directed that the Minute Entry be entered as a final judgment. Texas Industries appealed.

In their briefs and at oral argument the third-party defendants correctly asserted that no federal court had ever recognized a right of contribution among antitrust coconspirators. See Olson Farms, Inc. v. Safeway Stores, Inc., (1977-2) Trade Reg.Rep. (CCH) P 61,698 (D.Utah 1977), Argued and submitted, No. 77-2068 (10 Cir. March 16, 1979); El Camino Glass v. Sunglo Glass Co., (1977-1) Trade Reg.Rep. (CCH) P 61,533 (N.D.Cal.1976); Sabre Shipping Corp. v. American President Lines, Ltd., 298 F. Supp. 1339 (S.D.N.Y.1969).4 Unfortunately for the third-party defendants, however, the most recent, and only appellate, court to specifically consider this issue abruptly jettisoned the limited precedent and adopted the very position previously rejected by the district courts. In Professional Beauty Supply, Inc. v. National Beauty Supply, Inc., 594 F.2d 1179 (8 Cir. 1979), an Eighth Circuit panel, with one judge dissenting, held that an antitrust defendant should, at least under certain circumstances, be entitled to contribution from those "joint tortfeasors"5 not sued by the plaintiff in the main demand. Although we have carefully considered the arguments set forth in the majority's opinion, we are unable to agree that a right of contribution should be allowed among violators of the antitrust laws.

There is no statutory right of contribution provided for under either the Sherman Act, 15 U.S.C. § 1 et seq., or the Clayton Act, 15 U.S.C. § 12 et seq. We do not, however, interpret this omission as evidence that Congress necessarily intended to deny contribution under the antitrust laws. But see Sabre Shipping, supra, 298 F.Supp. at 1345. It is more likely that this narrow question, although a matter of some importance, never occurred to the drafters of the legislation. Our task, therefore, is to guess what Congress "would have intended on a point not present to its mind, if the point had been present."6 We agree with the case law that this issue must be resolved by reference to federal common law.7

Texas Industries advances a number of arguments for implication of a right of contribution. First, it argues that the deterrent effect of treble damages is dissipated by the possibility that only one of a number of conspirators would actually be liable for the injury. We conclude, consistent with prevailing economic theory,8 however, that that very possibility of imposition of sole liability has an enhanced deterrent effect. The chance that a participant may be faced with a full judgment is more likely to discourage anticompetitive conduct than would ensuring that each participant pays only some fair share. Allowance of contribution in effect ensures that the burden upon a particular defendant would be ameliorated by a division of liability. See Sabre Shipping Corp. v. American President Lines, Ltd., 298 F. Supp. 1339 (S.D.N.Y.1969); El Camino Glass v. Sunglo Glass Co., 1977-1 Trade Cases P 61,533 (N.D.Cal.1976). Even assuming, however, that the arguments concerning the relative deterrent effects are inconclusive, See Professional Beauty Supply, Inc. v. National Beauty Supply, Inc., 594 F.2d 1179 (8 Cir. 1979) (Hanson, J., dissenting in part), this inconclusiveness would hardly be a compelling reason upon which to base a rule allowing contribution. Id. at 1189.

Second, Texas Industries suggests that a rule prohibiting contribution would encourage collusion by the plaintiff with one or more of the potential defendants to the action. Similarly, the Eighth Circuit expressed concern that under a no-contribution rule a large or powerful wrongdoer would have sufficient economic influence to coerce a plaintiff into excluding it as a defendant. Although the possibility of collusion or coercion has always existed under a no-contribution rule, the courts and legislatures have not deemed this threat sufficient to counterbalance the advantages derived from denying contribution to wrongdoers. Texas Industries has not suggested that there has been collusion or coercion in this case, and we are unwilling to assume that the plaintiff engaged in or yielded to these tactics. Should a defendant establish that it is the victim of such maneuvering, it may well have an independent cause of action, at least as against its coconspirators.

Third, Texas Industries contends that a rule denying contribution is inconsistent with the Supreme Court's rejection of In pari delicto as a defense to an antitrust action in Perma Life Mufflers, Inc. v. International Parts Corp., 392 U.S. 134, 88 S. Ct. 1981, 30 L. Ed. 2d 982 (1968). Texas Industries reasons that if a participant in an unlawful scheme is not precluded from recovering treble damages from the other participants, no possible rationale can justify the denial of his right to seek contribution from his fellow wrongdoers.

As an initial matter, we are unable to agree with Texas Industries' assessment of the Court's decision in Perma Life. Notwithstanding the language in Justice Black's principal opinion,9 the decision does not endorse a wholesale rejection of the In pari delicto doctrine in an antitrust treble damages action. First, the Court made clear that the culpable plaintiff in that case was economically less powerful than the defendant and was not in any meaningful sense a voluntary participant in the illegal scheme. Id. at 139, 88 S. Ct. 1981. Consequently, the Court had no opportunity to decide whether a plaintiff might, wholly apart from In pari delicto, be precluded from recovery because of his "complete involvement" in the illegal scheme. Id. at 140, 88 S. Ct. 1981.

More important, five members of the Perma Life court emphasized their belief that some aspects of the In pari delicto doctrine should be retained under the antitrust laws. Id. at 146, 88 S. Ct. 1981 (White, J., concurring) (plaintiff barred where he and defendant bear "substantially equal responsibility" for injury); Id. at 147, 88 S. Ct. 1981, 1989 (Fortas, J., concurring in the result) (plaintiff barred where "the fault of the parties is reasonably within the same scale"); Id. at 149, 88 S.Ct. at 1989 (Marshall, J., concurring in the result) (plaintiff barred where he "actively participated in the formation and implementation of an illegal scheme"); Id. at 154, 88 S. Ct. 1981 (Harland, J., and Stewart, J., concurring in part and dissenting in part) (plaintiff barred who violated the law "in cooperation with defendant"). Subsequent lower court opinions have concluded that Perma Life refuses an In pari delicto defense only to those "plaintiffs who do not bear equal responsibility for creating and establishing an illegal scheme, or who are required by economic pressures to accept such an agreement." Premier Electrical Constr. Co. v. Miller Davis Co., 422 F.2d 1132, 1138 (7 Cir.), Cert. denied, 400 U.S. 828, 91 S. Ct. 56, 27 L. Ed. 2d 58 (1970). See Bernstein v. Universal Pictures, Inc., 517 F.2d 976 (2d Cir. 1975); Columbia Nitrogen Corp. v. Royster Co., 451 F.2d 3, 15-16 (4 Cir. 1971); See also Javeline Corp. v. Uniroyal, Inc., 546 F.2d 276, 278-79 (9 Cir. 1976); Dreibus v. Wilson, 529 F.2d 170, 174 (9 Cir. 1975); ABA Antitrust Law Developments 297-99 (2d ed. 1975).10

Furthermore, the partial rejection of the In pari delicto defense in Perma Life does not require that we recognize a right of contribution among antitrust coconspirators. There is an obvious and fundamental difference between a rule that bars suit by a plaintiff who in any way participated in the antitrust violation and a rule that forbids a defendant from obtaining contribution from his fellow wrongdoers. A rule barring any culpable plaintiff diminishes the deterrent effect of the antitrust laws by reducing the pool of potential private attorneys general who can instigate costly and uncertain antitrust litigation. However, as we previously noted, a rule prohibiting contribution among antitrust coconspirators not only does not frustrate deterrence but may very well enhance the statutes' deterrent effect by preventing a defendant from cutting its losses.11

Fourth, Texas Industries asserts that the denial of contribution in an antitrust context is inconsistent with the allowance of contribution under other federal statutes. A number of cases have recognized a right of contribution under certain provisions of the federal securities laws that do not expressly provide for such a right. Gould v. American Hawaiian Steamship Co., 387 F. Supp. 163 (D.Del.1974), Vacated on other grounds, 535 F.2d 761 (3d Cir. 1976); Alexander & Baldwin, Inc. v. Peat, Marwick, Mitchell & Co., 385 F. Supp. 230 (S.D.N.Y.1970), Aff'd per curiam, 442 F.2d 1376 (2d Cir. 1971); De Haas v. Empire Petroleum Co., 286 F. Supp. 809 (D.Colo.1968), Modified on other grounds, 435 F.2d 1223 (10 Cir. 1970). As these cases have recognized, however, both the Securities Act of 1933 and the Exchange Act of 1934 make express statutory provision for contribution,12 and the allowance of contribution in these cases can be explained under the general principle that the securities laws are to be administered In pari materia. Globus, Inc. v. Law Research Service, Inc., 318 F. Supp. 955, 958 (S.D.N.Y.1970), Aff'd per curiam, 442 F.2d 1376 (2d Cir. 1971); Fisher, Contribution in 10b-5 Actions, 33 Bus.Lawyer 1821, 1826 (1973); Note, Supra, 63 Cornell L.Rev. at 698 n. 85. Since there is no express provision for contribution under the antitrust laws, we are unable to use cases decided under the securities laws as authority for implying such a right in this case.

As further evidence of a judicial trend toward contribution in other areas of federal law, Texas Industries cites both FELA cases13 and sex discrimination cases decided under the Civil Rights Act.14 The FELA cases were negligence actions in which contribution was allowed on the basis of state law and, therefore, do not support Texas Industries' argument that a federal right of contribution should be extended to an antitrust defendant. The cases decided under the Civil Rights Act do not even discuss the rationales for allowing contribution. We decline to discard an established rule of law by relying on cases that offer no reasons.

Finally, Texas Industries proffers that denying contribution amounts to a taking of property without due process and equal protection of the laws as guaranteed by the Fifth Amendment. This constitutional violation is premised on the supposed unfairness which results when an antitrust defendant is forced to bear a disproportionate share of the damages caused by the conspiracy to which he was a party. Although we realize that the denial of contribution among wrongdoers, together with a plaintiff's right to sue and collect from only one defendant,15 can saddle a defendant with a substantial financial burden, we do not think the imposition of this burden offends constitutional principles.

The Fifth Amendment commands that the federal government refrain from depriving a person of his property "without due process of law." Due process has both a procedural and a substantive aspect. Procedural due process ensures the observance of certain procedural safeguards designed to afford protection against arbitrary governmental deprivation. Under this analysis, property may not be taken without providing the minimal protections of notice and an opportunity to be heard. Texas Industries does not, and cannot, claim a procedural due process infringement. The judicial proceeding required before the treble damages penalty can be imposed goes far beyond the threshold requirement of procedural due process.

Substantive due process requires that all legislation be rationally related to the furtherance of a legitimate governmental objective. Since the close of "the Lochner era"16 in the late 1930's judicial scrutiny of economic or social legislation has been virtually nonexistent. Instead, especially in the realm of economic regulation, the courts have exhibited great deference to legislative judgment and have upheld legislation if there is Any rational basis for enacting a particular economic measure. See, e. g., United States v. Carolene Products Co., 304 U.S. 144, 58 S. Ct. 778, 82 L. Ed. 1234 (1938). Indeed, the courts have even been willing to hypothesize legislative objectives and possible reasons for the law's enactment. See, e. g., Williamson v. Lee Optical Co., 348 U.S. 483, 75 S. Ct. 461, 99 L. Ed. 563 (1955).

Texas Industries' substantive due process argument cannot survive in such a harsh climate. We have no difficulty in concluding that a rule denying contribution to antitrust coconspirators comports with the "mere rationality" test utilized by the courts to scrutinize economic legislation. Although denying contribution may create a more severe penalty under the treble damages provision of the antitrust laws than exists at common law, the powerful deterrent effect provided by such a penalty is certainly a rational basis for a no-contribution rule.

Texas Industries' equal protection argument is equally unacceptable. The equal protection guarantee of the Fifth Amendment's due process clause17 requires that all governmental classifications rationally relate to a legitimate governmental purpose. The essence of the requirement is that the government treat all those similarly situated similarly. See Tussman & tenBroech, The Equal Protection of the Laws, 37 Calif.L.Rev. 341 (1949). In applying the equal protection rationality requirement, the courts have utilized various standards of review depending on the type of legislation being scrutinized. In reviewing economic regulation the courts have exhibited the same deference to legislative judgment accorded under a due process analysis. The test generally applied in such cases is whether there is any "conceivable basis" justifying the governmental classification.18 Under this analysis, denying contribution does not deprive Texas Industries of equal protection of the law. The purpose of the antitrust laws is to preserve and promote the public interest in competition by ensuring the existence of an open and free market. We cannot say that a no-contribution rule, because of its deterrent effect, is not rationally related to the achievement of this purpose.

Throughout this opinion we have treated all antitrust defendants as equally culpable, and, therefore, equally undeserving of contribution. An argument could be made, however, that a distinction should be drawn between intentional and unintentional violators. The crux of this argument rests upon the conclusion that an antitrust defendant whose liability is premised solely upon the illegal effects of its actions should not be treated as harshly as a defendant whose culpability arises from a determination of an illegal purpose. Even assuming that inequity may occur in a particular case, however, we believe that creating a contribution right for an unintentional violator may inimically affect the implementation of the antitrust laws. The possible detriments that can be envisioned make this an inappropriate case for the exercise of our power to shape the federal common law even to this limited extent.

First, allowing a right of contribution for an unintentional violator may diminish the deterrent function of trebled damages. As an initial matter, deterrence in reference to an unwitting price-fixer may appear to be irrelevant. We believe it reasonable to assume, however, that even businesses of the purest motives necessarily steer wide of any conduct the effects of which may violate the law, in the knowledge that full, trebled damages possibly await even an unintentional transgression. Allowing contribution may diminish this prophylactic, chilling effect by reducing the threatening specter of sole liability. Businesses may be encouraged to risk anticompetitive conduct secure in the knowledge that proof of illegal purpose is often impossible and that liability for illegal effects will be dissipated.

Second, the overall effects upon plaintiff's case of allowing contribution even for an unintentional violation are problematic. In Professional Beauty Supply, Inc. v. National Beauty Supply, Inc., 594 F.2d 1179 (8 Cir. 1979), the court, in allowing contribution for all antitrust defendants, dismissed this concern by pointing out that district courts have considerable discretion in managing complex cases to diminish any adverse effects upon plaintiffs. However, as Judge Hanson, a district judge sitting by designation, noted in his partial dissent, private plaintiffs may derive cold comfort from "the mere possibility of the favorable uses of district court discretion." Id. at 1190.

Aware that litigation may spiral out of their control, it is foreseeable that some plaintiffs will decide to forego a legitimate cause of action. Though district courts have the power to superintend complex litigation, the multiplication of issues and parties remains to be grappled with, and the chilling effect on the incentive to bring or pursue a lawsuit is unlikely to be diminished by the mere possibility of the favorable uses of district court discretion.

Id. at 1190. (Hanson, Jr., dissenting in part).

Similarly, a district judge in this circuit has rejected implication of third-party claims based upon his determination that such claim would be unmanageable. See In re Corrugated Container Antitrust Litigation, --- F.Supp. ---- (S.D.Tex.1979). These concerns expressed by district judges buttress our conclusion that allowance of third-party claims may open a Pandora's box of procedural problems, against which district court discretion may prove a palliation.

Third, there appears to be no reason for drawing a distinction between intentional and unintentional violators other than to ensure equity in a particular case. There may well be antitrust violators who are entirely unwitting, but we refuse to distort the antitrust laws in order to remedy a problematic inequity. Moreover, any contribution may well amount to a windfall of sorts for a defendant because of the fortuity of plaintiff's proof.

Our decision in this case is certainly subject to reasonable contrary arguments. In this area of interstitial lawmaking, however, to forge a new rule with questionable benefits and such possible detriments is a bad practice. Those aggrieved by this decision always have recourse to Congress, a forum better suited to evaluation of the competing interests and policies involved. In the absence of more compelling arguments in favor of contribution, this court is reluctant to create such a right as a matter of federal common law.

Affirmed.

LEWIS R. MORGAN, Circuit Judge, concurring in part and dissenting in part:

I concur in the majority opinion insofar as it denies a right of contribution to defendants who have intentionally violated the antitrust laws. I dissent, however, from the determination that an unintentional violator1 should be absolutely barred from seeking contribution from his fellow wrongdoers.

Historically, no right of contribution has been available among intentional tortfeasors. The courts have reasoned that limited judicial resources should not be wasted on a party whose cause of action is founded upon his own deliberate wrong. Restatement (Second) of Torts § 836A, Comment a (1979); Restatement of Restitution, Introductory Note to Ch. 3, Title C at 386 (1937). As noted in the majority opinion, Texas Industries has offered no convincing reason for departing from the common law no-contribution rule in the context of an intentional violation of the antitrust laws. What the majority fails to note is the modern trend toward recognizing a right of contribution among unintentional tortfeasors. Three fourths of the American jurisdictions2 now agree with Dean Prosser's observation that

(t)here is obvious lack of sense and justice in a rule which permits the entire burden of a loss, for which two defendants were equally, unintentionally responsible, to be shouldered onto one alone.

Prosser, Law of Torts § 50 at 307. Absent proof that the purposes of the antitrust laws would be frustrated under a limited contribution rule, I would, in the interest of fairness, award contribution to a defendant whose liability is based solely on an unintentional violation of the antitrust laws.

The majority suggests that awarding contribution to unintentional violators could undermine the antitrust law's effectiveness in discouraging anticompetitive behavior. According to the court's analysis, two problems arise even under a limited contribution rule: (1) the deterrent effect of the private damage action may be diminished if defendants are allowed to distribute the financial burden of a treble damages judgment and (2) the lawsuit will be made more complex and difficult to manage, thereby dissuading plaintiffs from bringing such actions. Neither argument is persuasive.

The deterrence argument has been relied on by courts as a reason both for denying and for awarding contribution in an antitrust case. Compare El Camino Glass v. Sunglo Glass Co. with Professional Beauty Supply, Inc., 594 F.2d 1179 (8th Cir. 1979). The majority opinion favors the position adopted by the district court in El Camino Glass that denying contribution Enhances the deterrent effect of the antitrust laws by preventing defendants from distributing the financial burden of a treble damages judgment. However, as the Professional Beauty Supply court noted, the argument can also be made that denying contribution Diminishes the law's deterrent effect by allowing some participants to avoid all responsibility for their wrongdoing. I agree with Judge Hanson's assessment that the arguments on either side of the deterrence question are at best inconclusive. Professional Beauty Supply, Inc., supra, 594 F.2d at 1189 (Hanson, J., dissenting in part). The deterrence argument, therefore, is an inadequate reason for rejecting a rule designed to achieve fairness among parties guilty of no conscious wrongdoing.

Furthermore, even if one accepts the premise that a no-contribution rule has an increased deterrent effect on those contemplating anticompetitive activity, this is no reason for denying contribution to unintentional violators. As Assistant Attorney General Shenefield recently observed in testimony before a Senate subcommittee considering a proposed bill allowing contribution in price-fixing cases,3 "(c)ontribution is most compelling where the tortious conduct is unintentional; In such situations a lack of contribution would have no deterrent effect."4 This position makes more sense than the court's conclusion that businesses will somehow "steer wide" of illegal activity which they never realized was illegal in the first place. Clearly, deterrence is a valid reason for denying contribution only among those who Intentionally violate the antitrust laws.

The court is also concerned that some businesses "may be encouraged to risk anticompetitive conduct secure in the knowledge that proof of illegal purpose is often impossible and that liability for illegal effects will be dissipated." Majority opinion at 905. The assumption that intentional violators will be able to pass themselves off as unwitting transgressors is inconsistent with the realities of the proposed contribution action. Any party seeking contribution will invariably be opposed by contribution defendants who have a vested interest in establishing that the contribution plaintiff was an intentional violator of the antitrust laws. Moreover, these contribution defendants, unlike many antitrust plaintiffs, will be in an excellent position to know whether the party was, in fact, an intentional wrongdoer. Under these circumstances few, if any, intentional tortfeasors will succeed in presenting themselves as unwitting transgressors.

In its second argument the court expresses concern that allowing contribution will make the lawsuit more complex and difficult to manage, thereby dissuading some plaintiffs from pursuing a legitimate cause of action. Although the authorities considering the question unanimously agree that permitting contribution does threaten the plaintiff's ability to control the size and scope of his lawsuit,5 they disagree as to the trial court's ability to recognize and eliminate that threat. It is clear the Fed.R.Civ.P. 42(b) authorizes trial judges to order separate trials whenever a plaintiff is inconvenienced or prejudiced by a defendant's expansion of his suit. Relying on language from Judge Hanson's dissent in Professional Beauty Supply, the majority warns that the discretionary nature of the separation remedy may nevertheless dampen some plaintiff's enthusiasm about initiating an antitrust action.

I simply cannot believe that the discretionary nature of the Rule 42(b) separate trials provision would discourage an antitrust plaintiff from seeking treble damages should the court recognize a right of contribution among unintentional violators. The district courts are certainly aware of the antitrust plaintiff's status as a private attorney general and of the important role played by the private damage action in enforcing the objectives of the antitrust laws. The special solicitude accorded these plaintiffs necessarily requires a liberal exercise of the separate trials provision. Realizing his favored position, the antitrust plaintiff is not likely to assume that the trial judge would deny separation and allow defendant to complicate the lawsuit or otherwise add to the private litigant's burden. Hence, the incentive to sue provided by the treble damages action is not jeopardized if contribution is allowed.

Although some unfairness to unintentional violators must be tolerated if antitrust law policy is thwarted by allowing contribution, I do not believe that the dangers envisioned by the majority withstand close scrutiny. Absent more convincing proof that a limited contribution rule would compromise the effectiveness of the antitrust laws, I would not force a defendant guilty of no conscious wrongdoing to bear total responsibility for the sins of many.
