In this second appeal generated by an antitrust class action against baby-formula manufacturers, appellants renew their argument that the district court’s exercise of diversity jurisdiction was improper because their claims did not satisfy the amount in controversy requirement of 28 U.S.C. § 1332 (1993). They alternatively contend that the district court erred in ruling that Louisiana antitrust law denied them standing due to their status as indirect purchasers. Since the precise issue of jurisdiction was decided by this court before, the law of the case prevents its being reconsidered. In addition, we have determined that the indirect purchaser question and the interstate/intrastate conspiracy question must be certified to the Louisiana Supreme Court because they represent important state antitrust law policy decisions for which no controlling precedent exists. Notwithstanding the certification, we affirm the district court’s dismissal of the Frees’ other claims.
*272 PROCEDURAL HISTORY
Appellants filed their class action petition against appellees Abbott Laboratories, Bristol-Myers Squibb Company, and Mead Johnson & Company (collectively “Abbott Labs”) in Louisiana state court alleging a price-fixing conspiracy. Appellees removed the case to federal district court. The Frees objected to the removal, arguing that the federal court lacked jurisdiction because they sought only $20,000 in damages and thus did not satisfy the $50,000 amount in controversy requirement then prescribed by 28 U.S.C. § 1332. The district court ruled that since Louisiana law provided for attorneys’ fees to be awarded to the named plaintiffs and not the attorneys, the amount recoverable by the plaintiffs exceeded the $50,000 threshold. However, the court applied the Colorado River abstention doctrine and tried to remand the case back to state court.
On appeal, this court agreed with the district court’s conclusion that diversity jurisdiction existed.
See In re Abbott Lab.,
Back in the federal district court, the Frees were unable to persuade the court that Louisiana antitrust law, unlike its federal counterpart, granted standing to indirect purchasers. The district court dismissed both the state law antitrust claims and the other state claims asserted by appellants.
DISCUSSION
A. Jurisdiction
Undeterred by this court’s previous decision, appellants again contend that the federal courts’ exercise of diversity jurisdiction was improper because them claims did not satisfy the amount in controversy requirement of 28 U.S.C. § 1332. The prior panel allegedly erred, according to the Frees, by crediting to them the class attorneys’ fees for purposes of calculating the amount in controversy and by applying Louisiana’s “procedural” attorneys’ fee law (Art. 595) in a federal diversity case. Although appellants’ argument bears on federal courts’ jurisdiction, this is not an issue that we will reconsider.
Once a panel of this court has decided an issue of law or fact, the decision continues to govern all subsequent stages of the same case.
See United States v. Becerra,
The Frees dispute application of the law of the case doctrine on two grounds. First, based on a recent
en banc
decision of this court, they urge that federal courts must constantly examine each ease for subject matter jurisdiction, and if it does not exist, must remand the case to state court.
See Marathon Oil Co. v. Ruhrgas,
The Frees’ second argument emphasizes that in a lawsuit removed from state court, as this was, “[if] at any time before final judgment it appears that the District Court lacks subject matter jurisdiction, the case shall be remanded.” 28 U.S.C. § 1447(c). And, reinforcing this language, the Supreme Court has observed that, “[d]e-spite a federal trial court’s threshold denial of a motion to remand, if, at the end of the day and case, a
jurisdictional
defect remains uncured, the judgment must be vacated.”
Caterpillar, Inc. v. Lewis,
The only ground of re-examination urged by the Frees, other than their complaint that the prior panel got it wrong on jurisdiction, is the Louisiana appellate court’s decision in
In re Gas Wafer Heater Prods. Liab. Litig.,
The issue of subject matter jurisdiction may not, for all of these reasons, be reconsidered in this appeal.
B. Other State Law Claims
Appellants argue that the district court erroneously dismissed their claims alleging violations of Louisiana’s general tort statute, La. Civ.Códe Ann. art. 2315 (West 1997), and fraud statute, La. Civ.Code Ann. art. 1953 (West 1997). The appellants’ arguments are unpersuasive.
The Frees rely on
Loew’s, Inc. v. Don George, Inc.,
Appellants next contend that they have stated a valid cause of action for fraud under Article 1953. However, “[t]o recover under Article 1953, [the Frees] must demonstrate the existence of a contract.”
Newport Ltd. v. Sears, Roebuck & Co.,
C. Motion to Certify Louisiana Antitrust Questions
The appellants have moved this court to certify the remaining two issues to the Louisiana Supreme Court. Specifically, they request certification concerning whether Louisiana antitrust law affords a cause of action to indirect purchasers of infant formula and whether Louisiana law prohibiting conspiracies “in restraint of trade or commerce in this state” applies to alleged interstate conspiracies.
“As a general proposition we are chary about certifying questions of law absent a compelling reason to do so; the availability of certification is such an important resource to this court that we will not risk its continued availability by going to that well too often.”
Jefferson v. Lead Indus. Assoc. Inc.,
1. Indirect Purchaser Rule
Appellants argue that the district court erred in concluding that Louisiana antitrust law denies standing to consumers of infant formula who are indirect purchasers from the defendant manufacturers. Louisiana antitrust law permits “any person who is injured” by an antitrust violation to sue the offender for treble damages, costs, and attorneys’ fees.
See
La. Rev. St. Ann. § 51:137 (West 1987).
4
Section 137 is nearly identical
*275
to the federal enforcement provision, § 4 of the Clayton Act,
5
which the United States Supreme Court has interpreted to deny standing to indirect purchasers.
See Illinois Brick Co. v. Illinois,
The Frees — and the Louisiana Attorney General as
amicus curiae
— urge that the Louisiana Supreme Court would decline to follow the federal indirect purchaser rale. The decisions of Louisiana courts have provided mixed signals on how to interpret state antitrust statutes when a corresponding federal rule exists. For example, in
Louisiana Power and Light Co. v. United Gas Pipe Line Co.,
[A]ny person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws may sue therefor in any district court of the United States ... and shall recover threefold the damages by him sustained, and the cost of suit, including a reasonable attorney’s fee.
2. Interstate/Intrastate Conspiracy
Louisiana antitrust law prohibits every “conspiracy, in restraint of trade or commerce in this state.... ” La. Rev. Stat. Ann. § 51:122 (West 1987). The parties disagree on the meaning of the term “in this state.” The Frees contend that it creates a cause of action for alleged interstate conspiracies that have the effect of restraining trade in Louisiana. Abbott Labs, on the other hand, argues that the statute covers only those conspiracies that are wholly intrastate. Because neither the language of the statute nor Louisiana caselaw resolves this important antitrust issue, we certify it to the Louisiana Supreme Court.
Each party supports its respective argument by referring to the plain language of the statute and to the canons of statutory construction. The Frees cite the “last antecedent” canon,
7
arguing that the qualifying
*276
phrase “in this state” applies to the immediately preceding phrase “trade or commerce.” Therefore, the statute should be read to prohibit any price-fixing conspiracy that' restrains trade in Louisiana. Abbott Labs counters with a canon of its own: “the act as a whole ought to be interpreted so that no clause, sentence, or word shall be superfluous, or meaningless, if that result can be avoided.”
Dore v. Tugwell,
In spite of these statutory arguments, the language of § 122 does not resolve the interstate/intrastate conspiracy issue. Neither do the decisions of the Louisiana courts. Each party cites
HMC Management Corp. v. New Orleans Basketball Club,
Finally, appellants refer to Judge Posner’s reasoning in
In re Brand Name Prescription Drugs Antitrust Litig.,
CERTIFICATION
Because these antitrust issues are matters of Louisiana law that will determine the outcome of this case and because there are no clear’ controlling precedents in the decisions of the Louisiana Supreme Court, we hereby *277 invoke the certification privilege granted by Louisiana Supreme Court Rule XII. 10
We certify the following questions to the Louisiana Supreme Court:
1) Does the Louisiana antitrust enforcement provision, La. Rev. St. Ann. § 51:137 (West 1987), follow the federal rule as outlined in Illinois Brick v. Illinois,431 U.S. 720 ,97 S.Ct. 2061 ,52 L.Ed.2d 707 (1977), and deny standing to indirect purchasers of products whose prices have been illegally fixed in an alleged conspiracy violative of the statute?
2) Does La. Rev. St. Ann. § 51:122 (West 1987), apply to an alleged interstate conspiracy to fix the wholesale price of infant formula that has the effect of restraining trade in Louisiana?
If the Louisiana Supreme Court accepts this certificate, the answers provided will determine the outcome of this appeal. We disclaim any intent that the Louisiana Supreme Court confine its reply to the precise form or scope of the legal questions certified. We retain cognizance of this case while pending before the Louisiana Supreme Court and transfer the record and appellate briefs with our certification to the Supreme Court of Louisiana.
Appellants’ motion to certify the indirect purchaser question and the interstate conspiracy question to the Louisiana Supreme Court is GRANTED.
Notes
. Although the Third Circuit disagreed with the Ninth and D.C. Circuits, its decision is not inconsistent with our present decision because it limits re-examination of prior decisions to "extraordinary circumstances [that] warrant such reconsideration.” ‘
Public Interest Research Group v. Magnesium Elektron, Inc.,
. Appellant’s argument is even more incongruous with Art. 2315, considering that the Civil Code provision is expressly addressed to negligent conduct. Antitrust price-fixing is hardly negligent.
. Since 1990, this court has certified only nine cases to the Louisiana Supreme Court.
See Hodgen v. Forest Oil Corp.,
.Section 51:137 reads:
Any person who is injured in his business or property by any person by reason of any act or *275 thing forbidden by this Part may sue in any court of competent jurisdiction and shall recover threefold the damages sustained by him, the cost of suit, and a reasonable attorney’s fee.
. 15 U.S.C. § 15 (1997). Section 4 of the Clayton Act reads in part:
. Several state courts have interpreted their own antitrust laws, which also mirror § 4 of the Clayton Act, to deny standing to indirect purchasers.
See Blewett v. Abbott Labs., Inc.,
.Under the "last antecedent” canon of statutory construction, a qualifying phrase in a statute "usually is construed to apply to the provision or clause immediately preceding it.”
In re RLV,
. The appellees also rely on
Al Copeland Enters. v. Jamplis,
. Our conclusion that the Louisiana Supreme Court should resolve this issue is reinforced by the subsequent events surrounding the
Prescription Dmgs
case. One year after die Seventh Circuit’s decision, the Alabama Supreme Court rejected
Prescription Dmgs
and held that its antitrust laws are limited to intrastate conduct.
See Abbott Labs. v. Durrett,
. Louisiana Supreme Court Rule XII, section 1 reads:
When it appears to the Supreme Court of the United States, or to any circuit court of appeal of the United States, that there are involved in any proceedings before it questions or propositions of law of this state which are determinative of said cause independently of any other questions involved in said case and that there are no clear controlling precedents in the decisions of the supreme court of this state, such federal court before rendering a decision may certify such questions or propositions of law of this state to the Supreme Court of Louisiana for rendition of a judgment or opinion concerning such questions or propositions of Louisiana law. This court may, in its discretion, decline to answer the questions certified to it.
