MCI TELECOMMUNICATIONS CORPORATION, Plaintiff,
v.
UNITED SHOWCASE, INC., Defendant.
Civ. A. No. 3:92-CV-2124-D.
United States District Court, N.D. Texas, Dallas Division.
April 1, 1994.
John C. Meinrath, Sen. Atty., Office of Gen. Counsel, MCI Tel. Corp., Richardson, Tex., for plaintiff.
No appearance for defendant.
FITZWATER, District Judge:
In this action to recover unpaid charges for interstate telecommunications services provided under the terms and conditions of a tariff filed pursuant to the Communications Act of 1934, 47 U.S.C. §§ 151-613 (the "Communications Act"), the court must decide whether the Fifth Circuit's recent opinion in MCI Tel. Corp. v. Credit Builders of Am., Inc., 980 F.2d 1021 (5th Cir.), vacated, ___ U.S. ___, 113 S.Ct. 2925, 124 L.Ed.2d 676, prior opinion reinstated, 2 F.3d 103 (5th Cir.), cert. denied, ___ U.S. ___, 114 S.Ct. 472, 126 L.Ed.2d 424 (1993), deprives it of subject matter jurisdiction. For the reasons set out, the court holds that an earlier Fifth Circuit panel opinion is binding precedent, *511 and that the court has subject matter jurisdiction.

I
Plaintiff MCI Telecommunications Corporation ("MCI") sues defendant United Showcase, Inc. ("United") to recover $18,116.50 in charges allegedly due for interstate telecommunications services provided to United. MCI contends this court has subject matter jurisdiction pursuant to 28 U.S.C. §§ 1331[1] and 1337[2] and the Communications Act. MCI sues as a provider of interstate telecommunications services, seeking to recover from defendant United for services rendered from April through August 1992 under the terms and conditions of MCI Tariff F.C.C. No. 1. This tariff is filed and maintained with the Federal Communications Commission ("FCC").
MCI initiated the present case in October 1992. It obtained service of process on defendant United by serving the Secretary of State of the State of Texas. Thereafter, on January 12, 1993 the Fifth Circuit filed its opinion in MCI, 980 F.2d 1021. Recognizing the effect of the decision on this lawsuit, MCI moved this court to stay the action, or transfer it to the inactive docket, pending the outcome of its petition for a writ of certiorari to the Supreme Court in the MCI case. The court granted this relief.
Thereafter, the Supreme Court granted MCI's petition and vacated the MCI panel's judgment. ___ U.S. ___, 113 S.Ct. 2925. MCI moved this court to reinstate this case on the active docket, which the court did. Following this, the MCI panel reinstated its opinion. 2 F.3d 103. MCI again moved this court to stay the instant case, or transfer it to the inactive docket, pending resolution of its petition for a writ of certiorari. The court granted the motion. Thereafter, the Supreme Court denied MCI's petition. ___ U.S. ___, 114 S.Ct. 472.
MCI moves this court to lift the stay currently in place, and to rule that the court has subject matter jurisdiction. Defendant United has neither appeared nor responded to MCI's motion. The matter is ripe for decision.

II
MCI's request to lift the stay is granted. There is no reason to defer the prosecution of this case, and it is now appropriate to reach the issue of the court's subject matter jurisdiction.

III
The dispositive question presented by MCI's motion for a ruling on subject matter jurisdiction is whether the MCI panel opinion is binding precedent. If it is, MCI concedes the decision unquestionably precludes a finding of subject matter jurisdiction.[3] MCI argues, however, that a prior panel opinion provides there is subject matter jurisdiction and that the earlier ruling is binding in this circuit.


*512 A
It is axiomatic in the Fifth Circuit that in the case of conflicting panel opinions, the earlier one controls, because one panel of the Fifth Circuit may not overrule another. In re Dyke, 943 F.2d 1435, 1442 (5th Cir. 1991). A subsequent panel "may not ignore the decision of a prior panel absent an intervening Supreme Court ruling, legislation, or a decision by this court sitting en banc." United States v. Gonzalez-Balderas, 11 F.3d 1218, 1222 (5th Cir.1994). "It has long been established that a legally indistinguishable decision of [the Fifth Circuit] must be followed by ... district courts unless overruled en banc or by the United States Supreme Court." Campbell v. Sonat Offshore Drilling, Inc., 979 F.2d 1115, 1121 n. 8 (5th Cir. 1992).

B
MCI urges that American Tel. & Tel. Co. v. Florida-Texas Freight, Inc. ("AT & T"), 357 F.Supp. 977 (S.D.Fla.), aff'd per curiam, 485 F.2d 1390 (5th Cir.1973), represents the law of the circuit and that it holds that a district court has subject matter jurisdiction in cases like the present one.
In AT & T a common carrier engaged in interstate communication by wire brought suit on an account for private line network telephone services provided to its customer. 357 F.Supp. at 978. The carrier and customer disputed the amount of a credit for service interruptions that the customer claimed should have been applied to the amount it owed for a particular month of service. Id. at 978-79. FCC Tariff No. 260 controlled the charges and credits for interstate private line service, and one provision of the tariff specifically provided for the manner of calculating credit allowances for service interruptions. Id. at 979.
The district court held that a tariff that is required by law to be filed constitutes the law and is not merely a contract. Id. (citing cases). It noted that tariffs validly filed in accordance with 47 U.S.C. § 203[4] operate *513 conclusively and exclusively to control the rights and liabilities between the parties. Id. (citing cases). Insofar as relevant to subject matter jurisdiction, the district court held that it possessed such jurisdiction "pursuant to 28 U.S.C. § 1337 in conjunction with 47 U.S.C. § 203." Id. at 978. The Fifth Circuit affirmed the district court "For reasons cogently expressed in the district court opinion." 485 F.2d at 1390.
This court holds that AT & T controls and that MCI must yield to it. The district court in AT & T expressly addressed the issue of subject matter jurisdiction and the Fifth Circuit affirmed for the "reasons cogently expressed in the district court opinion." Id. Even if the circuit panel had not spoken with unmistakable clarity regarding the extent of its affirmance  adopting both the result and reasoning of the lower court  the panel was obligated, sua sponte if necessary, to examine the district court's subject matter jurisdiction. Giannakos v. M/V Bravo Trader, 762 F.2d 1295, 1297 (5th Cir.1985) (per curiam). The AT & T panel did not find such jurisdiction to be lacking.
The MCI panel did not address AT & T and therefore did not attempt to distinguish it or to hold that it had been abrogated as binding precedent pursuant to intervening legislation, a ruling of the Supreme Court, or the en banc Fifth Circuit.[5] The panel instead acknowledged its preference "to take a more cautious approach with respect to the recognition of federal common law," citing two 1981 Supreme Court decisions that had emphasized the narrow reach of federal common law. See 980 F.2d at 1022. Although the MCI panel did not cite either Supreme Court opinion as being intervening authority that excused it from adhering to the holding of AT & T, this court will examine the decisions for that purpose because both opinions post-date AT & T.
The court concludes that neither City of Milwaukee v. Illinois, 451 U.S. 304, 101 S.Ct. 1784, 68 L.Ed.2d 114 (1981), nor Texas Indus., Inc. v. Radcliff Materials, Inc., 451 U.S. 630, 101 S.Ct. 2061, 68 L.Ed.2d 500 (1981), abrogates the precedential value of AT & T in this circuit. City of Milwaukee involved the question whether the Federal Water Pollution Control Act Amendments of 1972 affected a previously-recognized federal common law action to abate a nuisance caused by interstate water pollution. See 451 U.S. at 307-308, 101 S.Ct. at 1787. The Court held that Congress supplanted a federal common law remedy through enactment of the amendments. See id. at 332, 101 S.Ct. at 1800. Texas Indus. addressed whether a federal antitrust defendant had a right of contribution from other participants in an unlawful conspiracy. Id. 451 U.S. at 639, 101 S.Ct. at 2066. The Court held that if any such right existed, its source must be federal common law. Id. at 640, 101 S.Ct. at 2066. The Court observed the narrow areas in which federal common law existed, see id. at 642, 101 S.Ct. at 2067, and declined to adopt a common law right of contribution. See id.
Moreover, subsequent to both decisions, the Supreme Court held in Thurston Motor Lines, Inc. v. Jordan K. Rand, Ltd., 460 U.S. 533, 535, 103 S.Ct. 1343, 1344, 75 L.Ed.2d 260 (1983) (per curiam), that the district court had federal question jurisdiction in an action brought by a motor common carrier to collect freight charges pursuant to tariffs filed in accordance with the Interstate Commerce Act. The Court held the "carrier's claim is, of necessity, predicated on the tariff  not on an understanding with the shipper." Id. This decision is persuasive on the same issue under the Communications Act because of the common genesis, provisions, and objectives of these statutes. MCI Tel. Corp. v. Garden State Inv. Corp., 981 F.2d 385, 387 (8th Cir.1992).
*514 Nor is the AT & T panel opinion inconsistent with the rule in other circuits that recently have reached the same conclusion regarding subject matter jurisdiction under 28 U.S.C. § 1337. See MCI Tel. Corp. v. Graham, 7 F.3d 477, 478-79 (6th Cir.1993); MCI Tel. Corp., 981 F.2d at 388; Richman Bros. Records v. U.S. Sprint Communications Co., 953 F.2d 1431, 1438 (3d Cir.1991), cert. denied, ___ U.S. ___, 112 S.Ct. 3056, 120 L.Ed.2d 921 (1992). In fact, the Eighth Circuit in MCI Tel. Corp. cited AT & T for the proposition "that federal tariffs are the law, not mere contracts." 981 F.2d at 387 (citing AT & T and holding, "Although a user's refusal to pay charges fixed by a tariff will often arise in the context of a broken contract, the carrier's claim for payment is necessarily based on the filed tariff."). This court thinks the correct rule, recognized at least implicitly in AT & T, is that subject matter jurisdiction exists pursuant to 28 U.S.C. § 1337, in conjunction with 47 U.S.C. § 203, because the carrier's claim for payment is based on the filed tariff. See AT & T, 357 F.Supp. at 978-79.
In this court's view, there is nothing in congressional action, a Supreme Court decision, or an en banc Fifth Circuit opinion to undercut the jurisdictional holding of AT & T. Therefore, under settled Fifth Circuit law, the MCI panel opinion must give way to the binding effect of AT & T, and this court must respectfully decline to follow MCI.

MCI's motion to lift stay is granted. For the reasons stated, the court holds that it has subject matter jurisdiction in this case.
SO ORDERED.

[5]  It is possible that MCI did not argue for jurisdiction on the basis of the AT & T decision. See MCI, 980 F.2d at 1022 (noting bases for MCI's arguments but not citing AT & T opinion).
