Plaintiff-appellant Federal Express Corporation appeals the judgment of the district court dismissing on grounds of abstention its action seeking a declaration that the Tennessee Motor Carrier Act, Tennessee Code Annotated § 65-15-101
et seq.,
is expressly preempted by the Airline Deregulation Act of 1978, 49 U.S.C.App. § 1305, and impliedly preempted by the commerce clause,

Federal Express is a recognized leader in the overnight delivery business. “Approximately 90 percent of all packages transported by Federal Express are sorted at its Superhub in Memphis, Tennessee, the corporation’s principal place of business.”
Federal Express Corp. v. Tennessee Public Serv. Comm’n,
On July 2, 1986, the Tennessee Public Service Commission (TPSC) directed Federal Express to show cause why it was not subject to the Tennessee Motor Carrier Act, Tenn.Code Ann. § 65-15-102. A hearing was held before an administrative law judge (AU) who ruled that Federal Express was a motor carrier under Tennessee law and was therefore required to apply for a certificate of convenience and necessity from the TPSC. The TPSC reviewed the AU’s decision and following oral argument, the TPSC issued an order on June 9, 1987, ordering Federal Express to apply for a certificate of convenience and necessity to operate as an intrastate motor carrier. “The TPSC gave Federal Express 30 days to comply with its order, later extending that deadline to August 25, 1987.”
Federal Express,
On July 9, 1987, Federal Express filed with the Tennessee Court of Appeals a petition for review of the TPSC’s order and an application for an immediate stay of the order. On August 6, 1987, the Tennessee Court of Appeals denied the application for a stay of the TPSC’s order. In its one-page order, the court stated that the application for a stay was denied “on condition that compliance with said order of the Public Service Commission will not prejudice the prosecution of the present proceeding for review of said order.” J.A. at 653.
On August 7,1987, Federal Express filed the present action in the district court seeking declaratory and injunctive relief against the TPSC. 1 Federal Express argued that the Tennessee Motor Carrier Act was expressly preempted by the Airline Deregulation Act of 1978, 49 U.S.C.App. § 1305, and impliedly preempted by the commerce clause. Federal Express filed a motion for a temporary restraining order which the district court granted on August 10, 1987. The district court stated in its order that there was a substantial risk of irreparable injury to Federal Express “because submission to the jurisdiction of the Public Service Commission by filing an application may render moot the plaintiff’s constitutional and federal statutory claims, and unduly interfere with and harm the *965 plaintiff’s alleged integrated transportation system developed under federal authorization.” J.A. at 135-36.
On September 9, 1987, prior to the district court’s hearing arguments on the motion for a preliminary injunction, Federal Express filed a motion to voluntarily dismiss its petition for review in the Tennessee Court of Appeals, which the court granted on September 11, 1987. Pursuant to a motion by the TPSC, the district court consolidated the hearing on the motion for a preliminary injunction with a bench trial on the merits, and the consolidated proceeding was conducted on September 11 and 12, 1987.
On June 16, 1988, the district court issued an opinion and order dismissing the case for lack of federal subject matter jurisdiction.
See Federal Express Corp. v. Tennessee Public Serv. Comm’n,
Federal Express appealed the dismissal of its action and a panel of this court initially affirmed the judgment of the district court.
Federal Express Corp. v. Tennessee Public Serv. Comm’n,
On remand, the parties briefed the abstention issue, and following a hearing, the district court entered an order on April 23, 1990, dismissing the action on the basis of the abstention doctrine of
Younger v. Harris,
The principal issue on appeal is whether the district court erred by applying the Younger abstention doctrine.
II.
A. Waiver
Before reviewing the district court’s application of the
Younger
abstention doctrine, we must address Federal Express’ contention that the TPSC has waived the abstention argument. Federal Express argues that the TPSC waived any abstention argument because it did not plead abstention in its answer, it did not file a motion for abstention, it urged the district court to hold a hearing on the merits of the case, and at the hearing, counsel for TPSC stated that abstention was no longer an issue in the ease since the state court appeal had been dismissed. Federal Express asserts that the TPSC raised the
Younger
abstention argument for the first time two months after the bench trial when the district court asked the parties to brief the issue of res judicata. Thus, Federal Express contends that the TPSC waived the abstention argument by not actively pursuing the issue.
See City of Paducah v. Investment Entertainment,
Younger
abstention is “designed to allow the State an opportunity to ‘set its own house in order’ when the federal issue is already before a state tribunal.”
Ohio Bureau of Employment Services v. Hodory,
In the present case, the abstention issue was first raised by the district court during a status conference on August 20, 1987. Although the TPSC did not plead abstention in its answer, Federal Express has cited no case requiring abstention to be raised in the pleadings. Indeed, the Supreme Court has indicated that “abstention may be raised by the court
s'ua sponte.” Bellotti v. Baird,
After the district court raised the abstention issue, the TPSC filed a supplemental trial brief on September 2, 1987, arguing for abstention. However, in its brief, the TPSC argued for Burford-type
3
abstention rather than
Younger
abstention. At the outset of the consolidated hearing and trial before the district court on September 11-12, 1987, the district judge directed the parties to address the abstention issue. The TPSC urged the district court to abstain, arguing that abstention is appropriate where “there is an ongoing State proceeding where the Federal plaintiff has a chance to raise his constitutional is-sue_” J.A. at 366. The TPSC cited
Ohio Civil Rights Comm’n v. Dayton Christian Schools,
After receiving evidence and testimony on the merits, the court heard arguments from the parties on September 12, 1987, during which counsel for TPSC conceded that abstention was no longer an issue in the case because there was no pending state court action. However, counsel for intervenor Purolator Courier argued that under the Younger doctrine the abstention issue remained alive until the Tennessee Court of Appeals acted on Federal Express’ motion to dismiss its appeal. The court invited the parties to submit supplemental briefs, and on November 12, 1987, the TPSC filed a supplemental brief retracting counsel’s concession at the hearing that abstention was no longer an issue in the case. The TPSC stated that further research had revealed that Younger abstention, rather than the Burford-type, was *967 applicable to this case, and that the abstention issue was not mooted by Federal Express’ dismissal of its state court appeal.
Our review of the proceedings in the district court reveals that the TPSC did not waive the abstention argument. As noted earlier, the TPSC was not required to raise abstention in the pleadings. When the district court raised the issue sua sponte, the TPSC argued for abstention. With the exception of the concession made by the TPSC at the hearing on September 12, 1987, which was retracted by its supplemental brief, the TPSC has persistently argued for abstention. Moreover, we view the TPSC’s motion to consolidate the preliminary injunction hearing with a trial on the merits as a means of avoiding duplica-tive proceedings rather than a request for the court to reach the merits of the constitutional issue. Furthermore, it should be noted that on October 6, 1989, this court remanded this case to the district court for further proceedings including consideration of the question of abstention. Accordingly, we conclude that the TPSC did not waive the abstention argument.
B. Abstention
We conduct a
de novo
review of a district court’s abstention decision.
Litteral v. Bach,
[FJirst, do [the relevant state proceedings] ... constitute an ongoing state judicial proceeding; second, do the proceedings implicate important state interests; and third, is there an adequate opportunity in the state proceedings to raise constitutional challenges.
Middlesex County Ethics Comm. v. Garden State Bar Ass’n,
In
CSXT, Inc. v. Pitz,
whether the state court has concurrent judicial jurisdiction to decide the preemption question, and, if the answer to that question is “Yes,” whether a federal court should abstain in favor of ongoing state proceedings originating in the state regulatory agency.
Id. at 473-74.
Federal Express attempts to distinguish CSXT by arguing that the preemption language in the Airline Deregulation Act, 49 U.S.C.App. § 1305, “absolutely prohibits economic regulation by state agencies of the activities of a certificated air carrier.” Appellant’s Brief at 20. The statutory language relied on by Federal Express states:
Except as provided in paragraph (2) of this subsection, no State or political subdivision thereof ... shall enact or enforce any law, rule, regulation, standard, or other provision having the force and effect of law relating to rates, routes, or services of any air carrier having authority under subchapter IV of this chapter to provide air transportation.
49 U.S.C.App. § 1305(a)(1). The key phrase is “relating to rates, routes, or services of an air carrier.”
Id.
Federal Express relies on three recent decisions holding that state regulation of an air carrier’s rates, routes, or services was preempted by section 1305(a).
See Trans World Airlines, Inc. v. Mattox,
In Mattox the court observed:
An examination of the preemption language in § 1305(a)(1) and its legislative history leads to the conclusion that Congress did intend to preempt so completely the particular area of state laws “relating to rates, routes, or services” as to preclude state court actions. Congress preempted this area to maintain uniformity and to avoid the confusion and burdens that would result if interstate and international airlines were required to respond to standards of individual states. We agree with the First Circuit that Congress “did not intend to leave a vacuum to be filled by the Balkanizing forces of state and local regulation.” New England Legal Foundation,883 F.2d at 173 . Congress made this clear by including the express preemption provision in the Deregulation Act.
Mattox,
Federal Express argues that since preemption under section 1305 is clear, the district court erred by abstaining from ruling on the merits. Federal Express attempts to distinguish
CSXT
by arguing that “the nature of the regulation in
CSXT
was so intertwined between state and federal governments that there was no clear argument that tensions cut in favor of federal rather than state action.” Appellant’s Brief at 19. Finally, Federal Express asserts that “prosecution of the state proceedings, particularly in the absence of a stay pending full appellate review ‘threatens impairment of federal rights,’
CSXT,
We reject Federal Express’ argument against abstention on the basis of federal preemption.
5
In our view, Federal Express has failed to distinguish our ruling in
CSXT.
In
CSXT,
we held that the presence of a preemption issue would not modify the classic abstention analysis so long as the state court has concurrent judicial jurisdiction to decide the preemption question. “State courts normally have concurrent jurisdiction of federal issues unless such jurisdiction is withdrawn by federal statute.”
CSXT,
Before applying the three-part
Younger
analysis, we briefly address the implications of the Supreme Court’s decision in
New Orleans Public Serv., Inc. v. Council of New Orleans,
The first inquiry under the
Younger
analysis is whether the state proceedings constitute an ongoing state judicial proceeding. The district court applied the day-of-filing rule to conclude that the underlying state proceedings were ongoing. Federal Express contends that there was no ongoing state proceeding which it sought to enjoin. Federal Express argues, “Deference to a state proceeding is not due when the ‘administrative proceedings have ended,’ and where ‘no state trial has taken place and no injunction against a pending state proceeding is sought.’ ” Appellant’s Brief at 29 (quoting
Thomas v. Texas State Bd. of Medical Examiners,
In
Zalman v. Armstrong,
The second inquiry under the Younger analysis is whether the state proceedings implicate important state interests. The district court held that this element of Younger was satisfied because Tennessee has an important interest in regulating intrastate trucking. Federal Express does not challenge the district court’s ruling on this point. Accordingly, the second prong of the three-part test is satisfied.
The final inquiry is whether there was an adequate opportunity in the state proceedings to raise constitutional issues. The district court concluded that this element was satisfied because Federal Express’ constitutional claims could have been raised in the pending state proceedings. Federal Express argues that it did not have an adequate opportunity to protect its federal statutory and constitutional claims because the state court refused to grant a *970 stay of the licensing process. Federal Express contends that without a stay it would have to file an application for a certificate of public convenience and necessity with the TPSC, and it asserts that voluntary submission to the TPSC’s jurisdiction would threaten to moot its federal constitutional and statutory claims.
Federal Express’ argument misconceives the nature of the inquiry, The “pertinent inquiry is whether the state proceedings afford an adequate opportunity to raise the constitutional claims_”
Moore v. Sims,
In
Watts v. Burkhart,
III.
For the foregoing reasons, the judgment of the district court is AFFIRMED.
Notes
. "Purolator Courier, a competitor with Federal Express that has complied with the Tennessee Motor Carrier Act, was permitted to intervene as a defendant.”
Federal Express,
. Federal Express' reliance on Judge Wellford's concurring opinion in City of Paducah is misplaced because in that case Judge Wellford concluded that the abstention issue had been abandoned on appeal, not waived by failure to raise it in the district court. Moreover, a concurring opinion has no binding authority.
.
Burford v. Sun Oil Co.,
. The only court to address this specific issue reached the opposite conclusion. In
Federal Express Corp. v. California Public Util. Comm'n,
. The TPSC asserts that Federal Express did not raise this preemption argument in the proceedings before the district court on remand. However, we conclude that the preemption argument was adequately presented to the district court and we address the merits of the issue.
. We note that the Tennessee Court of Appeals denied Federal Express’ request for a stay on condition that compliance with the TPSC's order would not prejudice judicial review of the order.
