Opinion for the Court filed by Senior Circuit Judge SWYGERT.
This appeal arises out of an antitrust action brought by Southern Pacific Communications Company and Transportation Microwave Corporation (“SPCC”) against American Telephone and Telegraph Company and the local Bell Operating Companies (“AT & T”). Following a bench trial, the district court entered judgment for AT
&
T and this court affirmed.
SPCC v. AT & T,
I
The facts of the antitrust action underlying this appeal are fully set forth in
SPCC v. AT & T,
1. SPCC’s Rule 60(b) Motion
The district court issued a Memorandum Opinion and Order entering judgment for AT & T and dismissing the case with prejudice on December 21, 1982. In February 1983 SPCC moved the district court, pursuant to Fed.R.Civ.P. 60(b)(6), to vacate the judgment in light of judgments in two other antitrust actions against AT & T,
MCI Communications Corp. v. AT & T,
No. 74-C-633 (N.D.Ill.1980),
aff'd in part and rev’d in part,
SPCC claims that the jury verdict in the MCI case precludes relitigation by AT & T of five factual issues. 2 The first issue is the definition of the relevant market. 3 The other four issues are whether AT & T willfully maintained its monopoly power by: (1) negotiating interconnection contracts in bad faith and then abandoning the contract process in bad faith to file tariffs with state regulatory commissions; 4 (2) improperly denying FX and CCSA interconnections; 5 (3) providing inappropriate or ineffective equipment and procedures for interconnection; 6 and (4) refusing to *1015 provide interconnections outside strictly-limited geographical areas.
SPCC also claims that the judgment in
United States v. AT & T, supra,
A final judgment or decree ... rendered in any ... proceeding brought by ... the United States under the antitrust laws to the effect that a defendant has violated said laws shall be prima facie evidence against such defendant in any action or proceeding brought by any other party against such defendant under said laws as to all matters respecting which said judgment or decree would be an estoppel as between the parties thereto: Provided, That this section shall not apply to consent judgments or decrees entered before any testimony has been taken. Nothing contained in this section shall be construed to impose any limitation on the application of collateral estoppel____
15 U.S.C. § 16(a) (1982).
2. The MCI Case
In 1974 MCI filed a complaint against AT & T in the United States District Court for the Northern District of Illinois under section 4 of the Clayton Act, 15 U.S.C. § 15 (1982), alleging monopolization and conspiracy in restraint of trade. The case was tried to a jury between February and June 1980. Fifteen of MCI’s monopolization charges were ultimately submitted to the jury which was instructed to make a separate finding of liability as to each charge but permitted to award damages in a lump sum. The jury found in favor of MCI on ten of the fifteen charges and awarded MCI $600 million in damages. After losing various posttrial motions, AT & T filed notice of appeal in August 1980. In September 1980 MCI filed notice of cross-appeal. On January 12, 1983 the United States Court of Appeals for the Seventh Circuit issued its opinion sustaining in part and reversing in part the jury verdict and remanding the case for a new trial on the issue of damages.
MCI v. AT & T,
SPCC filed its complaint against AT & T on March 27, 1978. In February 1982 SPCC made a motion in limine for an order defining legal issues under section 2 of the Sherman Act. In one of its briefs filed in connection with the motion, SPCC argued that the jury verdict in the MCI ease precluded AT & T from relitigating the issue of the relevant market. Plaintiffs’ Reply Memorandum on Section 2 of the Sherman Act, at 2-3 (filed Feb. 17, 1982). This issue, among others, was referred to two Special Masters. On April 22, 1982 the Special Masters ruled:
[I]n MCI v. AT & T a finding of fact was made by the jury as to the relevant market. The finding was in response to a charge to the jury reciting that MCI contended the relevant market was "intercity business and data communication services in the United States during the period from 1969 through mid-1974,” consisting of “private line services, and other services which can be used instead of private line services, such as WATS and business long distance.” That finding is the basis of a judgment now on appeal. *1016 If that finding is not reversed on appeal, it may be relied on by SPCC.
The issue is obviously substantially the same, and should be treated as such unless AT & T can suggest some reason why it should not be regarded as the same issue. On the premise that it is the same issue, the finding is preclusive against AT & T, Parklane Hosiery Co. v. Shore,439 U.S. 322 [99 S.Ct. 645 ,58 L.Ed.2d 552 ] (1979), unless AT & T can show “compelling circumstances” permitting it to relitigate this issue____ If the finding in MCI v. AT & T is reversed, or compelling reasons are shown why the finding should not be preclusive here, then the definition of the market in this case is a question of fact to be determined afresh according to accepted antitrust legal standards.
Opinion of the Special Masters at 5-6 (filed Apr. 22, 1982) (hereinafter “Special Masters’ April 22 opinion”).
AT & T appealed the Special Masters’ April 22 Opinion and, in response, SPCC filed a motion to adopt the Opinion with modifications, Plaintiffs’ Motion to Adopt, with Modifications, the Special Masters’ April 22 Opinion, at 7-9 (filed May 3, 1982). The district court deferred consideration of the appeal pending trial. Order Holding in Abeyance Special Masters’ 4-22-82 Opinion (May 6, 1982). Trial in the case commenced on May 10, 1982 and lasted for more than thirty days. In July 1982 SPCC filed proposed conclusions of law, in which SPCC proposed that AT & T be estopped from challenging the definition of the relevant market adopted by the jury in the
MCI
case. Plaintiffs’ Proposed Findings of Fact and Conclusions of Law, at 355 (filed July 21, 1982). On December 21, 1982 the district court issued a Memorandum Opinion and Order entering judgment for AT & T. Without reference to the Special Masters’ April 22 Opinion, the court defined the relevant market as interstate, intercity private line services to customers other than the federal government.
SPCC v. AT & T, supra,
3. The Government Case, United States v. AT&T
In 1949 the United States filed an antitrust action against Western Electric Company and AT & T in the United States District Court for the District of New Jersey.
United States v. Western Electric Co.,
The MFJ as modified by the court required the defendants to divest themselves of their local operating companies.
Id.
at 226-27. The MFJ provides: “Neither this Modification of Final Judgment nor any of its terms or provisions shall constitute any evidence against, an admission by, or an estoppel against any party or BOC.”
Id.
at 228. In its opinion approving the MFJ, the court discussed the applicability of section 5(a) of the Clayton Act, 15 U.S.C. § 16(a) (1982): “[T]he statute establishes a presumption usable in private litigation only on the basis of a judgment ‘to the effect that a defendant has violated the antitrust laws.’ ”
4. The District Court Decision
In a written opinion and order issued on July 7, 1983 the district court denied SPCC’s Rule 60(b) motion.
SPCC v. AT & T, supra,
II
Fed.R.Civ.P. 60(b)(6) provides a district court discretion to grant relief from a judgment for any reason justifying relief.
See SEC v. Clifton,
*1018 III
1. Waiver
The district court found that SPCC waived its collateral estoppel claims with respect to the
MCI
case.
SPCC v. AT & T, supra,
SPCC claims that it felt constrained by the Special Masters’ April 22 Opinion to wait for the Seventh Circuit’s decision to issue before seeking to preclude relitigation of the MCI jury findings. The Opinion stated that SPCC could rely on the jury finding as to the relevant market “[i]f that finding is not reversed on appeal____” We note that the federal rule and the rule in this circuit is that collateral estoppel may be applied to a trial court finding even while the judgment is pending on appeal.
See Huron Holding Corp. v. Lincoln Mine Operating Co.,
First, the discussion of collateral estoppel in the Special Masters’ Opinion is ambiguous. The reference to the pending appeal of the MCI jury verdict could be interpreted to mean that the appellate court’s decision would be considered only if and when it issued; if the district court issued its decision on SPCC’s complaint before the Seventh Circuit issued its decision in the MCI case, the district court would be required to give collateral estoppel effect to the jury verdict provided the propriety of giving such effect was established by SPCC; if, however, the Seventh Circuit issued its decision before the district court issued its decision, the district court obviously would be required to give collateral estoppel effect only to those findings upheld by the Seventh Circuit. Under this interpretation of the Special Masters’ April 22 Opinion, an interpretation which comports with the federal rule, see 1B J. Moore, Federal Practice, supra, ¶ .416[3], SPCC remained free to pursue its collateral estoppel claims at trial.
The foregoing approach to collateral estoppel presents a potential dilemma for every litigant seeking to preclude litigation of certain issues on the basis of a prior judgment that is pending on appeal. If a litigant relies on the trial court judgment for proof of a contested issue and the judgment on that issue is reversed on appeal before judgment is rendered in the litigant’s case, the litigant has no remaining proof on the issue. The remedy for this problem, however, is to permit the litigants to reopen their case after a reversal to present their evidence on the issue, or to
*1019
permit the litigants to submit independent proof on the issue at the same time they argue for the application of collateral estoppel. The remedy is not to refrain from raising collateral estoppel claims until the prior judgment has been affirmed on appeal.
See Grantham v. McGraw-Edison Co., supra,
Collateral estoppel serves three main purposes. It protects litigants from the burden of relitigating an issue which the other party has already litigated and lost.
See Parklane Hosiery, supra,
Finally, we are concerned, as was the district court,
see SPCC v. AT & T, supra,
2. Definition of the Relevant Market
We are unable to conclude, however, that SPCC waived its collateral estoppel claim regarding the MCI jury finding on the relevant market. SPCC filed a motion in limine to preclude relitigation of the relevant market issue, filed a motion to adopt the opinion of the Special Masters which found collateral estoppel applicable to the MCI jury finding on the relevant market, and filed a proposed conclusion of law that AT & T be estopped from relitigating the relevant market issue.
We find, however, that error, if any, committed by the district court in failing to adopt the
MCI
jury verdict with respect to the definition of the relevant market is harmless. The definition of the relevant market has no independent significance under the Sherman Act. It relates only to the determination of whether a defendant possesses monopoly power.
See United States v. E.I. duPont De Nemours & Co., supra,
IV
Waiver has not been raised with respect to SPCC’s collateral estoppel claims based upon the judgment entered in the government’s suit against AT & T. The MFJ was approved by the district court in August 1982.
United States v. AT & T, supra,
SPCC appears to try to root a collateral estoppel argument in the 1980 amendment to section 5(a) of the Clayton Act, 15 U.S.C. § 16(a).
See
Appellant’s Opening Brief, No. 83-1864, at 42-43. The amendment provides: “Nothing in this section shall be construed to impose any limitation on the application of collateral estoppel____” Act of Sept. 12, 1980, Pub.L. 96-349, § 5(a), 94 Stat. 1157. We believe that the correct approach is to analyze collateral estoppel and section 5(a) separately. Collateral estoppel, under which a prior judgment operates as an absolute bar to relitigation of the issues estopped, is governed by common law principles.
See, Parklane Hosiery Co. v. Shore, supra,
1. Collateral Estoppel
Some courts have given collateral estoppel effect to consent judgments.
But see Seaboard Air Line R.R. v. George F. McCourt Trucking, Inc.,
The district court’s refusal to allow the use of collateral estoppel is further supported on the ground that it would be unfair to AT & T to give estopping effect to the MFJ. The MFJ settled a complicated antitrust action involving a fast-changing communications market. We will not pretend to be able to understand the various, complex considerations of the parties to the settlement. We recognize only that AT & T could have agreed to the settlement for a variety of reasons and not necessarily because AT & T was convinced that the government could establish an antitrust violation.
Cf. United States v. AT & T, supra,
2. Section 5(a)
Section 5(a) of the Clayton Act, by its terms, applies to consent judgments entered after testimony has been taken.
See United States v. National Ass’n of Broadcasters,
The MFJ contains no liability findings. The only mention of liability is the nonliability clause. Although the district court which approved the MFJ considered the evidence of an antitrust violation, the court expressly stated that its observations were based on incomplete evidence and were not intended to be a final determination on the liability of AT & T.
United States v. AT & T, supra,
Because we conclude that the district court did not err in denying SPCC’s request to apply section 5(a) to the MFJ, we need not address the question whether AT & T successfully rebutted any prima facie effect of the MFJ.
V
We sustain the district court’s denial of SPCC’s Rule 60(b)(6) motion on the ground that any error involving the definition of the relevant market was harmless. SPCC waived its other estoppel claims with respect to the MCI case, and the MFJ entered in the government’s case was entitled to neither collateral estoppel nor prima facie effect. The judgment is AFFIRMED.
Notes
. Fed.R.Civ.P. 60(b)(6) provides:
On motion and upon such terms as are just, the court may relieve a party or his legal representative from a final judgment, order, or proceeding for ... any ... reason justifying relief from the operation of the judgment.
. In
Parklane Hosiery Co. v. Shore,
. The relevant market is the market in which an entity’s power is measured to determine whether the entity is a monopolist for antitrust law purposes. The relevant market is generally defined in both geographic and product terms.
