We render this opinion not only to decide the case before us, but also to resolve an intra-circuit conflict on an important and recurring issue implicating removal from and remand to state court. For the reasons set *3forth below, we hold that a covered employee’s claims and the claims of those asserting rights through the employee against the employer’s workers’ compensation insurance carrier for breach of the duty of good faith and fair dealing are not immunized against removal to federal court by the provisions of 28 U.S.C. § 1445(c). We conclude that such a claim is not a civil action “arising under” the state workers’ compensation law; rather, such a claim — basically an insurance malpractice tort — -is separate from and independent of a claim for statutory workers’ compensation benefits, regardless of the fact that such a tort claim is “related to” a compensation benefits claim and to the workers’ compensation insurance coverage of the claimant’s employer.

FACTS AND PROCEEDINGS
Plaintiff-Appellant Jimmy Charles Patín, Sr. sustained a work-related injury on October 2, 1990, while employed by Defendant Allied-Signal, Inc. (Allied). He continued to work for Allied without loss of time or compensation until he was discharged on November 2, 1990. As Allied’s workers’ compensation insurance carrier, Defendant-Appellee Travelers Indemnity Company of Rhode Island (Travelers) paid medical bills for Patin’s treatment but never initiated payment of weekly workers’ compensation benefits because (1) Patín had lost no time as a result of his work-related injury, and (2) he had a preexisting physical limitation in his shoulder.
On March 21, 1991, Patín filed a workers’ compensation claim with the Texas Industrial Accidents Board (IAB), which awarded Patín $42,091.02 in connection with the October 1990 accident. Both parties to that administrative proceeding appealed in a suit de novo filed in state district court. At the completion of the jury trial that ensued, Patin’s award was increased to $75,021.88 for permanent partial disability; his claim for total temporary disability was rejected.
In another action, Patín sued Allied in federal court for age discrimination and wrongful discharge, claiming that Allied had retaliated against him for filing the workers’ compensation claim for the October 1990 accident. In that case, a federal jury rendered a verdict in favor of Allied, producing a take-nothing judgment adverse to Patín.
Yet a third lawsuit implicating Patin’s October 1990 accident — the suit from which this appeal arises — was filed by Patín and his wife, Margaret (collectively, the Patins), on July 23, 1993, in the 128th Judicial District Court, Orange County, Texas. It included, among others, a claim against Travelers for breach of the duty of good faith and fair dealing. Travelers removed the case to federal district court on the basis of diversity of citizenship. The Patins timely filed a motion to remand this case to state court, contending that (1) as an insurance company conducting business in Texas, Travelers is a de facto citizen of that state, and thus removal is not proper; and (2) no proof existed that the required $50,000 minimum jurisdictional amount was met. In addition, the Patins’ motion made mention, in connection with the de facto citizenship argument, of the fact that Travelers does business under the Texas Workers’ Compensation Act (TWCA). The Patins concluded their remand motion with the statement that “[t]he cause should be remanded because the outcome depends entirely on claims under the Texas Workers’ Compensation Act, and there are not [sic] federal questions.” After a full hearing in October 1993, the district court denied the Patins’ motion to remand.
In February 1994, Travelers filed a motion for summary judgment, insisting that the Patins’ claims were barred by both the statute of limitations and the doctrine of res judicata. In August 1994, subsequent to a full merits hearing on that motion, the district court granted summary judgment in favor of Travelers. The following month the Patins timely filed a motion for reconsideration, but it too was denied by the district court.1
*4The Patins timely filed their notice of appeal from the district court’s denial of that post-judgment motion. On appeal the Patins insist that 28 U.S.C. § 1445(c) mandates remand to state court because their claims against Travelers arise under the TWCA.2 Predictably, the Patins also assert that neither the doctrine of res judicata nor the applicable state statute of limitations bars their claims.

ANALYSIS
A. Standard of Review
We review the district court’s grant of a motion for summary judgment de novo, applying the same standard as the district court applied.3 Questions of law are decided just as they are outside of the summary judgment context: de novo.4
B. Remand to State Court
1. Jurisdictional Amount and De Facto Citizenship
In the district court the Patins, citizens of Louisiana, contended that subject matter jurisdiction was wanting in federal district court for the following reasons: (1) the summary judgment evidence was insufficient to demonstrate that the amount in controversy was equal to or exceeded $50,000, and (2) Travelers was a de facto citizen of Texas by virtue of the way it does business there.5 We agree with the district court’s determination that the requirements for diversity jurisdiction under 28 U.S.C. § 1332 were present and that 28 U.S.C. § 1441(b) does not prevent removal. Presumably the Patins do too, as they do not challenge these holdings on appeal.
2. Remand under 28 U.S.C. § 14.4.5(c)
Before us, the Patins rely solely on § 1445(c) as justification for remand. They contend that all of their claims against Travelers “aris[e] under Workmen’s Compensation laws” of Texas; as such, the removal of this case from state court was void, and the case therefore must be remanded to state court. In response, Travelers offers two theories on which it urges us to affirm the district court’s denial of remand and retention of jurisdiction: (1) The Patins have waived their right to insist on remand; and (2) the Patins’ common law claim that Travelers breached the duty of good faith and fair dealing, their Texas Insurance Code claim, and their claim of civil conspiracy, were all “separate and independent claims” from the claims for statutory workers’ compensation benefits that they advanced in their IAB/ state court litigation, confirming that the Pa-tins’ action cannot come within the purview of the non-removability provisions of § 1445(e). We address Travelers’ two theories in sequence.
a. Waiver
If Travelers is correct that the Pa-tins have waived their right to claim improper removal, our remand inquiry is at an end, and we need not consider non-removability under § 1445(c). Travelers insists that the Patins neither cited nor relied on § 1445(c) in their Motion to Remand or in their argument to the district court at the hearing on that motion. Rather, states Travelers, remand based on § 1445(c) was raised for the first time in the Patins’ motion for a new trial (reconsideration), thereby failing to comply with the requirement of § 1447(c) that “[a] motion to remand the case on the basis of *5any defect in removal procedure must be made within 30 days after the filing of the notice of removal under section 1446(a).”6 Travelers notes correctly that in this circuit the wrongful removal of a civil action arising under a state’s workers’ compensation law is a procedural defect that is waivable under § 1447(c).7 Patín no longer disputes that diversity is complete, so the instant claim clearly could have been brought originally in federal court. As such, the following rule of this circuit applies:
If a plaintiff initially could have filed his action in federal court, yet chose to file in state court, even if a statutory provision prohibits the defendant from removing the action and the defendant removes despite a statutory proscription against such removal, the plaintiff must object to the improper removal within thirty days after the removal, or he waives his objection.8
Although Travelers correctly recites the applicable law when it asserts that the Patins’ removal complaint is procedural in nature and thus waivable, the facts eschew waiver. True, § 1445(c) was neither quoted nor cited by section number in the Patins’ removal motion or in their argument to the district court at the hearing on that motion. Nevertheless, the substantive concept embodied in § 1445(c) — non-removability of claims arising under state workmen’s compensation laws — was adverted to in the motion and was discussed, however briefly, in the hearing. Moreover, in contesting removal Travelers apparently addressed briefly the issue of non-removability and referred to § 1445(e) by number, thereby eliminating any question whether that ground for remand was before the district court. Thus, we reject Travelers’ contention that the Pa-tins waived their right to insist on remand to state court.
b. “Arising Under” the Texas Workers’ Compensation Act
The intra-circuit conflict alluded to in the introductory portion of this opinion was created by diametrically opposed jurisprudential answers to the question whether an employee’s claim against his employer’s workers’ compensation insurance carrier for the breach of its duty of good faith and fair dealing “arises under” the workers’ compensation laws of the state. Federal district courts of this circuit are split on the issue.9
We begin by reiterating a basic rule of this circuit that the “arising under” standard expressed in § 1445(c) should be interpreted broadly and in a manner consistent with our interpretation of that standard under § 1331, which governs federal question jurisdiction.10 We see that admonition followed by the district court in Almanza v. Transcontinental Ins. Co., a ease relied on by the Patins, at least by analogy.11 The Almanza court reasoned that, inasmuch as *6proof of a viable workers’ compensation claim is an essential element of a claim against the compensation insurance carrier for breach of the duty of good faith and fair dealing, the workers’ compensation statute creates the cause of action and the claim arises under that law.12 The district court reasoned further that placing good faith and fair dealing claims within the scope of § 1445(c) serves the important policy function of allowing courts of the states to vindicate the policies embodied in their workers’ compensation schemes.13
Travelers distinguishes the situation in Jones v. Roadway Express, Inc.14 from the circumstances in the good faith and fair dealing cases that relied — erroneously, according to Travelers — on Jones. Travelers correctly observes that the cause of action underlying the retaliatory discharge claim at issue in Jones was created not by Texas common law but by statute, with specific reference to workers’ compensation claims.15
Historically, workers injured in Texas could not recover more than the statutory remedies contained in the compensation statute.16 In 1988, however, the Texas Supreme Court recognized an employee’s common law cause of action in tort for the breach — by an employer’s workers’ compensation insurance carrier- — of the duty of good faith and fair dealing in the mishandling of the employee’s compensation benefits claim.17 Nevertheless, the Texas Supreme Court in Aranda made clear, as have the state appellate courts in the cases that have followed, that good faith and fair dealing claims arise under common law, not under the compensation statute.18 This is consistent with the fact that damages for breach of good faith and fair dealing are not measured by reference to the exclusive remedy provisions of the TWCA.19
Even if we were inclined to stop at this point, though, our inquiry could not be deemed complete. For, although state law may create the cause of action and define the claim, federal law governs whenever our consideration involves construction of a removal statute.20 Those of our federal district courts that have held that bad faith claims do not arise under the state statute have, like the state courts, relied on the independent tort nature of such claims, i.e., that the duty to deal fairly and in good faith is created by the common law, not by the compensation statute.21 For example, in Warner v. Crum & Forster Commercial Insurance Co.,22 the most recent federal ease holding that claims for breach of that duty are removable because they do not arise under the TWCA, the district court speculated that “[i]f the Texas legislature were to codify the duty of good faith and fair dealing, its codification un*7doubtedly would be with laws pertaining to the obligations of insurers generally, not with worker’s compensation laws.”23 Given the general nature of the duty and the broad spectrum of relationships to which it can apply, the Warner court concluded that good faith and fair dealing claims are only “incidentally related” to the workers’ compensation statute and the underlying contract providing compensation benefits.24
Walker v. Health Benefit Management Cost Containment, Inc.,25 is the only published post-Almanza opinion from a district court of this circuit to hold that bad faith claims are not removable. The Walker court construed § 1445(c) as reflecting a strong Congressional policy to defer to the states in the area of workers’ compensation.26 In Walker the district court placed great weight on what it characterized as the “almost laughable anomaly” that would be created if the bad faith claim were removable while the claim for benefits, on which it depends, were not.27 We’re not laughing: Perhaps on deeper analysis the Walker court too would have perceived the situation to be more serious and less amusing; for, in actuality, these claims are quite often severed at the state level.
Indeed, as most states have enacted expedient and less expensive administrative procedures for adjudicating claims of injured workers,28 we interpret the policy underlying § 1445(c) somewhat differently than did the Walker court. Section 1445(c) was passed to encourage the use of just such administrative procedures and to prevent the undue burden that is placed on the worker when an action is removed to federal court, where such procedures generally do not apply. That underlying policy does not appertain, though, when the cause of action at issue is independent of the administrative procedures applicable to a state workers’ compensation claim — as are claims for breach of the duty of good faith and fair dealing.
' Given (1) the cogent analysis of the Texas Supreme Court that claims against insurers “arise under” the common law, not under the TWCA, (2) the foregoing analysis of the purpose of § 1445(c), and (3) the burgeoning administrative treatment of workers’ compensation claims in the several states, we conclude that claims for the breach of the duty of good faith and fair dealing do not “arise under” the state workers’ compensation statutes but are, at most, “related to” those statutes and thus do not come within the ambit of the non-removability provision of § 1445(c).29 We therefore affirm the ruling of the district court rejecting the Patins’ motion to remove and their more recent motion to reconsider. As this holding confirms the diversity jurisdiction of the district court and sustains the district court’s rejection of the removal and remand challenge mounted by the Patins, we turn now to consider the next hurdle that the Patins must clear to prevail, res judicata.
C. Res Judicata
• Recall that Patín initiated three lawsuits in the wake of his work-related accident and employment termination by Allied. In addition to the instant suit against Travelers and to the employment discrimination suit against Allied, the Patins also filed a lawsuit in the state district court in Orange County, Texas, arising out of the Patins’ successful (but, in his opinion, undercompensated) claim with the LAB. In the Orange County suit, Patín successfully increased his benefit award against Travelers from $45,091.02 to $75,021.88.
The district court in the instant case concluded that, even though the Patins did not *8assert the good faith and fair dealing claim against Travelers in their state court suit for compensation benefits, they could have and should have done so. We agree.
In federal court, the preclusive effect of a prior state court judgment is governed by state law.30 Under Texas law, a prior judgment “precludes a second action by the parties and their privies not only on matters actually litigated, but also on causes of action or defenses which arise out of the same subject matter and which might have been litigated in the first suit.”31
The Patins dispute neither that rule nor its applicability in federal court; instead, they insist that Patin’s attempt to amend his pleadings in the employment discrimination suit against Allied immunizes the Patins’ claims against Travelers in the instant suit from the doctrine of res judicata. In advancing this theory, the Patins rely on Turner v. Richardson I.S.D.32 In Turner a state district court held that res judicata did not bar litigation of pendent state law claims over which a federal district court had previously refused to exercise supplemental jurisdiction.33
We find Turner inapposite, affording no support for Patin’s contention. Regardless of Patin’s failed efforts to include the instant good faith and fair dealing claim in his erstwhile discrimination suit against Allied, the Patins clearly made no attempt, either originally or subsequently, to include the breach of good faith and fair dealing claim against Travelers in the state court compensation benefit suit against that insurer; neither is there any showing that the state trial judge denied the Patins the opportunity to bring or add such claims.34
In that state court compensation suit against Travelers, the Patins could have included or added claims for breach of that insurer’s duty of good faith and fair dealing—a cause of action that arose from the same subject matter as did their benefits claims, i.e., Travelers’ failure or refusal to pay compensation to Patín following his work-related October 1990 accident.35 Thus, the district court’s dismissal of the instant suit as barred by the doctrine of res judicata was correct and is hereby affirmed. As a result, we need not, and therefore do not, reach the question whether the Patins’ claims against Travelers are time barred as well.
Ill
CONCLUSION
The Patins could have brought their claim against Travelers for its alleged breach of the duty of good faith and fair dealing by filing suit in federal district court in the first place. It follows, then, that the Patins’ objection that the removal of their state court suit violated § 1445(e) implicates a procedural defect in that removal. As such, their objection was waivable. Nevertheless, the record on appeal demonstrates that the Pa-tins’ timely—if inartfully—placed non-remov-ability under § 1445(c) before the district court in their Motion to Remand and again in their argument at the hearing on that motion. Thus, they did not waive their right to contest removal on grounds of a violation of § 1445(c).
We hold, however, that the breach of the duty of good faith and fair dealing by a carrier of workers’ compensation insurance is *9an independent tort created by — and thus “arising under” — the common law, and is at most “related to” the workers’ compensation laws that create the basic benefit rights of the covered employee and those claiming through him.36 Consequently, the non-re-movability provisions of § 1445(c) are inapplicable to claims grounded in a breach of that duty. The district court’s denial of remand in the instant case was correct. Also correct was the district court’s determination that res judicata bars the Patins’ claims based on Travelers’ alleged breach of the duty of good faith and fair dealing.
As we affirm the rulings of the district court on both removal and res judicata, we affirm that court’s dismissal of the Patins’ claims against Travelers.

Marino dealt with a cause of action that arose post-judgment and thus could not have been asserted in the prior case, clearly distinguishable from the Patins' situation.
. Non-retroactive amendments to the Texas Workers’ Compensation Statute post-dated the accrual of the Patins' cause of action and thus could not affect the § 1445(c) issue in this case. See Acts 1989, 71st Leg., 2nd C.S., ch. 1, § 10.41 (repealed and codified at Tex.Lab.Code Ann. § 416.001) (providing that certain actions taken by the carrier in reliance on the Commission or the benefit review officer are not actionable for breach of the duty of good faith and fair dealing); and § 416.002 (placing a cap on the quantum of damages recoverable from á compensation carrier on a claim for breach of the duty of good faith and fair dealing). Even if these amendments had been in effect when the Patins' cause of action accrued, they would not change our con■clusion that a cause of action for breach of that duty “arises under" the common law; these statutory amendments at most "relate to” that common law cause of action, and therefore do not affect the § 1445(c) question.
