Defendant-appellee Travelers Insurance Company (“Travelers”) removed this action to the federal district court despite the provision in 28 U.S.C. § 1445(e) forbidding removal of cases arising under state workers’ compensation laws. ' Plaintiff-appellant Clyde Ar-mistead unsuccessfully resisted the removal on jurisdictional grounds, but overlooked the bar of section 1445(c). The district court granted summary judgment in Travelers’ favor. On appeal, Armistead for the first time invokes section 1445(c). We hold that the district court lacked subject matter jurisdic *45 tion in this ease. Accordingly, we vacate the judgment below and direct that the case be remanded to state court.
I
Armistead, a citizen and resident of Maine, worked as a truck driver for C -& M Transport, Inc. (“C & M”), a Maine corporation. He was injured on May 7,1987, while driving a C & M truck in Maryland. Appellee Travelers, a Connecticut corporation, was at one time C &.M’s workers’ compensation insurer.
Armistead filed a petition for benefits under the Maine Workers’ Compensation Act, 39 M.R.S.A §§ 1-195 (repealed), 1 in October, 1987. The Workers’ Compensation Commission issued a benefits award in February, 1988 (after C & M defaulted), but no compensation payments were made. The Commission’s award indicates “no record of insurance,” and as for C & M, it filed for Chapter 7 protection, was adjudicated bankrupt, and ceased doing business. According to the record before us, Travelers had notified the Commission that it had canceled C & M’s coverage for nonpayment of premiums, effective some three weeks before the date of .injury.
In July of 1992, Armistead resumed his quest for benefits by seeking a Commission determination that Travelers was liable on the award because it had failed to send a prior notice of the cancellation to C & M, as required by state law. See 39 M.R.S.A. § 23(1) (1987) (repealed); see also 39-A M.R.S.A. § 403(1) (1992). After informal proceedings failed to resolve the claim, Armi-stead filed a formal motion for enforcement of the award. Travelers denied liability and cross-moved for a review of Armistead’s alleged disability. The statute contemplates an evidentiary hearing before a Commissioner on such motions, subject to appellate review in the Commission and a discretionary appeal to Maine’s highest court. See 39 M.R.S.A. §§ 94-B, 98-99,103-A, 103-B, 103-C.
While these motions were pending before the Commission, Armistead also filed, a complaint in the state superior court for enforcement of the Commission’s original award. The complaint alleged a right to relief by virtue of the superior court’s equitable power to enforce Commission orders under the Workers’ Compensation Act, 39 M.R.S.A. § 103-E. Count 1 sought enforcement of the award against C & M; count 2 sought a declaration that Travelers afforded coverage to C & M under the Act on the date of injury, and also sought enforcement of the Commission’s award against Travelers .and C & M jointly.
Travelers promptly removed the action to federal district court, claiming diversity of citizenship between Travelers and Armi-stead, and describing the action as one for “breach of contract.” Seven months later, Armistead moved for a remand to the state court, arguing that'C & M’s Maine citizenship destroyed complete diversity between the parties. But there was a rub; C & M had not been served with process, and its very existence was dubious.

The district judge dismissed the claim against C & M and, applying the holding of
White v. United States Fidelity & Guar. Co.,
On appeal, Armistead ádds for the first time the argument that the removal violated 28 U.S.C. § 1445(c). Travelers urges that section 1445(c) is inapplicable because Armi-stead’s suit does not “arise under” Maine’s workers’ compensation law, and, alternatively, that Armistead waived the argument.
II
Section 1445(c) renders nonremovable suits “arising under” the workers’ compensation laws of the state in which the federal court sits. The statute reflects a congressional concern for the states’ interest in administering their own workers’ compensation schemes, the burdens on injured claimants of maintaining a federal court suit, and the incidence of federal court congestion.
See generally Horton v. Liberty Mut. Ins. Co.,
Travelers does not directly assert a right to remove the proceedings pending before the Commission, but focuses solely on the subsequent superior court complaint. While the complaint was a separate filing, however, it did not comprise independent litigation based on a separate common law right to relief. Rather, the complaint sought statutory compensation under a provision of the workers’ compensation law vesting in the superior court equitable powers to enforce Commission orders and to issue
pro forma
decisions enforcing Commission benefit awards.

As an integral part of the administrative enforcement scheme, the superior court action was merely supplementary to the Commission proceeding, and both proceedings obviously arose under the workers’ compensation law within the meaning of 28 U.S.C. § 1445(c).
Cf. Spearman v. Exxon Coal USA,
Removal of the case thus was doubly barred, once under section 1445(e), and again because the supplementary superior court proceeding does not independently qualify as a removable “civil action” under 28 U.S.C. § 1441(a).
See Barrow v. Hunton,
Ill
Under 28 U.S.C. § 1447(c), a motion challenging subject matter jurisdiction may .be *47 made at any time, but objections based on a “defect in removal procedure” must be made within thirty days of the removal. Travelers argues that Armistead waived any objection to the lack of removal jurisdiction by failing to move for a remand within this period.
In
Williams v. AC Spark Plugs Div. of Gen. Motors Corp.,
The Eighth Circuit, however, has taken the view that where Congress expressly restricts removal jurisdiction over a particular class of cases, wrongful removal should not be treated as a “mere procedural irregularity” waivable by the parties, but as a violation of the court’s limited subject matter jurisdiction.
The fact that [plaintiff] could have invoked the original jurisdiction of the federal court initially is irrelevant.... The jurisdiction of the lower federal courts, both original and removal is entirely a creature of stat-ute_ If one of the statutory requirements is not. met, the district court has no jurisdiction.
Hurt v. Dow Ch
em.
Co.,
We need not choose between these contradictory views because in this case there was neither removal jurisdiction nor original diversity jurisdiction. Unlike the Texas statute at issue in
Williams,
Maine’s compensation scheme does not permit a
,de novo
state court action for workers’ compensation benefits.
See Dorey v. Forster Mfg. Co.,
Moreover, the limited supplementary and appellate authority exercised by the Maine courts over Commission proceedings finds no analog in federal diversity jurisdiction. As courts of
original
jurisdiction, federal district courts sitting in diversity jurisdiction do not have appellate power, nor the right, to exercise supplementary equitable control over original proceedings in the state’s administrative tribunals.
See Rooker v. Fidelity Trust Co.,
We need go no further. In the absence of federal subject matter jurisdiction, we cannot proceed to the merits of this appeal, and the case must be remanded to the state court.
See Halleran v. Hoffman,
Accordingly, the judgment is vacated and this case is remanded to the district court which shall immediately remand the action to the state court. All parties shall bear their own costs.
Notes
. The legislature retrofitted the Act with neoteric provisions which took effect on January 1, 1993.
See
39-A M.R.S.A. §§ 101-409. The new law alters benefits and replaces the Workers’ Compensation Commission with an administrative board.
See
39-A M.R.S.A. §§ 151, 152. Transitional provisions preserve benefits under the former law for 'injuries sustained before January 1, 1993, and continue the Commission’s authority overpending claims for a limited period.
See generally Clark v. International Paper Co.,
. Armistead renews here the claim that C
&
M retains its corporate existence under Maine's corporation laws, and is a “necessary” party to this suit. The argument was not fully developed below, and we deem it waived.
See Ryan v. Royal Ins. Co.,
. Commission orders are enforceable only by petition to the superior court, which may issue “any suitable process” in aid of Commission proceedings.
See
39 M.R.S.A. §§ 93; 103-E. The Commission itself has no general equity powers.
See Clark v. International Paper Co.,
. Any claim in this case not covered by the foregoing principles would be subject to dismissal under the related doctrine of
Burford-type
abstention. The state has signalled its interest in regulatory coherency by concentrating all claims in an exclusive administrative process, and parallel federal suits could "in a very real sense ... disrupt the regulatory scheme.”
