ON APPEAL FROM THE 

UNITED STATES DISTRICT 

COURT FOR THE EASTERN 

DISTRICT OF MICHIGAN

BEFORE: ROGERS, SUTTON, and STRANCH, Circuit Judges.

ROGERS, Circuit Judge. This cross-appeal concerns whether attorney’s fees were 

properly awarded to plaintiffs in a collective bargaining dispute subjected to arbitration. PlaintiffsAppellees, retirees and a labor union representing former automotive manufacturing workers,

brought suit in federal district court under a previously negotiated collective bargaining agreement 

alleging breach of contract, breach of fiduciary duty, and violations of the Employee Retirement 

Income Security Act. Per the terms of the CBA, the district court entered an order requiring 

plaintiffs to arbitrate all of their claims. The neutral arbitrator rendered a favorable decision for 

plaintiffs on the contractual claim but declined to award attorney’s fees pursuant to a fee waiver

provision in the agreement. On a subsequent motion to recover attorney’s fees before the district 

court, the district court reopened the case, granted judgment in favor of plaintiffs on the ERISA 

claim, denied attorney’s fees for costs incurred through the date of the arbitrator’s award, but 

awarded attorney’s fees incurred after the date of arbitration. Because all of plaintiffs’ claims were

2

subject to mandatory arbitration, and the arbitrator is the only entity empowered to conduct 

factfinding and fashion a proper remedy for arbitrable labor claims, the district court had no 

authority to enter summary judgment on the ERISA claims or to award plaintiffs post-arbitration 

ERISA fees. 

This is the second time that the attorney’s fees issue in this case has been before us. In the 

earlier appeal, we lacked appellate jurisdiction to review the district court’s order determining that 

TRW Automotive U.S. LLC (“TRW”) is liable for the UAW and retired plaintiff employees’ 

attorney’s fees under the Employee Retirement Income Security Act (“ERISA”) because the 

district court had not yet determined the amount to be awarded. The issue is now ripe for review, 

as the district court has awarded UAW $183,300.91 in attorney’s fees and costs. 

TRW operated an automotive plant in Sterling Heights, Michigan, which closed in 2006. 

TRW entered into a series of collective bargaining agreements (“CBA”) with the International 

Union, United Automobile, Aerospace, and Agricultural Implement Workers of America 

(“UAW”) and its then Local 247, the collective bargaining representatives of some of TRW’s 

Sterling Heights employees. The last CBA was negotiated in 2002. After TRW announced that it 

planned to close the Sterling Heights plant in 2005, TRW and the UAW were unable to negotiate 

a closing agreement. Instead, they agreed to extend the 2002 CBA, which remains in effect. 

The 2002 CBA provides health insurance coverage for active and retired employees. 

Originally, the 2002 CBA provided health insurance coverage under Blue Cross Blue Shield. In 

2007, TRW changed the default health insurance carrier to Humana. Because Humana did not 

offer a plan that perfectly corresponded to the 2002 CBA’s requirements, TRW voluntarily 

provided its employees with coverage that exceeded the CBA’s requirements to account for the 

differences in the health plans. Subsequently, in 2011, TRW notified its former employees that it 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

3

planned to replace the Humana health care coverage with Health Reimbursement Accounts 

(“HRA”) that TRW would fund at its discretion. 

In response, the UAW and several retirees filed suit in October 2011. Plaintiffs alleged 

that the proposed HRA arrangement “material[ly] reduc[ed]” their health care benefits and that 

TRW therefore breached the 2002 CBA, violated ERISA (29 U.S.C. § 1132(a)(1)(B) and (a)(3)), 

and breached its fiduciary duty. Plaintiffs brought their breach of contract claim pursuant to § 301 

of the Labor Management Relations Act (“LMRA”), 29 U.S.C. § 185. Plaintiffs requested various 

forms of relief, including attorney’s fees, which are at issue here.

In January 2012, TRW filed a motion to compel arbitration of plaintiffs’ claims pursuant 

to the 2002 CBA. TRW argued that the parties had agreed to arbitrate all disputes regarding 

TRW’s compliance with the CBA. The 2002 CBA states:

4.1 Exclusive Remedy: The Union and the employees agree that the grievance and 

arbitration procedures provided herein are adequate to provide a fair and final 

determination of all grievances which may arise out of the employment relationship 

during the term of this Agreement and that such procedures shall be the exclusive 

remedy for the enforcement by them of any claim against the Company.

The following section of the CBA defines the term “grievance”: 

4.1.1 Grievance Defined. A grievance is any complaint, dispute or controversy in 

which an employee or the Union claims that the Company has failed to carry out a 

provision of the Agreement and which involves a question concerning the 

interpretation or application of or compliance with this Agreement, including any 

question relating to the rates of pay, hours of work and other conditions of 

employment of any employee.

Further, Section 4.4 of the CBA confines the scope of the arbitrator’s authority and requires each 

party to bear their own attorney’s fees in the event of arbitration. The 2002 CBA declares:

4.4. Step III, Arbitration . . . The impartial arbitrator shall not have authority to alter 

or modify this agreement. Each party shall bear the expense of its own 

representatives; and all other expenses of the arbitration, if any, shall be shared 

equally by the parties. The award of the impartial arbitrator shall be final and 

binding upon the parties and upon all employees and persons affected, all of whom 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

4

agree to abide by his award. The expenses of the impartial arbitrator, if any, shall 

be shared and paid equally by the parties.

The district court granted TRW’s motion to compel arbitration in September 2012. In light 

of TRW’s successful motion to compel arbitration, the court dismissed the case without prejudice 

and permitted any party to file a motion to reopen the case after arbitration. 

Plaintiffs appealed the district court’s order compelling arbitration. While the appeal was 

pending, the arbitrator ruled in April 2013 in plaintiffs’ favor on the question of whether TRW 

breached its contractual duties under the CBA. Plaintiffs then moved for voluntary dismissal of 

their appeal of the district court’s order compelling arbitration, and we granted the motion.

After the district court compelled arbitration, plaintiffs requested a broad array of relief 

from the arbitrator. They asked the arbitrator to declare that TRW’s substitution of retirement 

health insurance coverage with HRAs breached the CBA, violated ERISA, and breached TRW’s 

fiduciary duties. Plaintiffs also requested that the arbitrator “[d]irect TRW to cease its CBA 

breaches and ERISA violations” and 

[d]irect TRW to pay the costs and expenses and attorney fees of UAW, class 

counsel, and the retirees and their dependents and surviving spouses encompassed 

by this arbitration, incurred in connection with the litigation and arbitration 

proceeding, under 29 U.S.C. § 1132(g)(1) and otherwise, and to pay such other

costs, expenses, fees, compensatory, and exemplary amounts as may be 

warranted[.]

Prior to the arbitration hearing, the parties had stipulated that “[t]he [cross-motions for summary 

judgment submitted to the Arbitrator] will be limited to the issues of contract interpretation and 

breach.” However, the stipulation also stated that “[t]he parties each reserve the right to present 

further evidence to address issues unresolved by the Arbitrator’s decision on the motions, 

including any factual disputes; ERISA issues; etc.” The arbitrator accordingly described the issue 

before him as “whether the adoption of the HRA structure as implemented by TRW constitutes a 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

5

breach of contract.” The arbitrator issued his decision in April 2013, determining that TRW 

breached the 2002 CBA when it transferred the retirees from their Humana health care coverage 

to the HRAs.

The arbitrator ordered TRW to restore the retirees’ health care coverage back to the 

Humana coverage to remedy its breach of the CBA. However, the arbitrator declined to grant 

plaintiffs’ request for attorney’s fees pursuant to Section 4.4 of the CBA, which provides that each 

party must bear the cost of its own representatives.

TRW filed a separate action in May 2013 to partially vacate the arbitration award. TRW 

argued in a motion for summary judgment filed in September 2013 that the arbitrator exceeded his 

authority because the arbitration award required TRW to provide a level of benefits that exceeded 

what was required under the CBA. The district court denied TRW’s motion and affirmed the 

arbitrator’s award in January 2018. The court determined that the arbitrator’s award was 

appropriate because it was reasonable for the arbitrator “to conclude that the parties had agreed to 

modify the CBA to have the Humana plan replace the Blue Cross Blue Shield plan.” TRW 

appealed. 

Plaintiffs, on the other hand, did not ask the arbitrator to make any additional findings and 

did not move the district court to vacate any portion of the arbitrator’s decision. In October 2013, 

plaintiffs filed a motion for attorney’s fees and expenses under ERISA. Plaintiffs also filed a 

renewed motion for summary judgment later that same month, arguing that TRW’s breach of the 

CBA constituted a violation of health benefits vested under ERISA (the “ERISA vesting claim”). 

In response, TRW opposed the motion for attorney’s fees and filed a motion to strike plaintiffs’

renewed motion for summary judgment. TRW argued in part that the motions were actually an 

untimely challenge to the arbitrator’s decision denying plaintiffs’ request for attorney’s fees and 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

6

that the district court lacked subject matter jurisdiction over the renewed motion for summary 

judgment. 

The district court granted plaintiffs’ renewed motion for summary judgment and denied 

TRW’s motion to strike in January 2018. The district court determined that the arbitrator ruled 

only that TRW breached the CBA and did not address plaintiffs’ ERISA vesting claim. The court 

concluded that plaintiffs’ renewed motion for summary judgment was therefore not a challenge to 

the arbitration award subject to the three-month limitations period and was accordingly not time 

barred. The court granted plaintiffs’ renewed motion for summary judgment, reasoning that

TRW’s violation of the CBA also constituted a violation of ERISA. But the court dismissed 

plaintiffs’ motion for attorney’s fees without prejudice because it was premature, as it was filed 

before the court had decided plaintiffs’ ERISA claim. Plaintiffs then filed a second motion for 

attorney’s fees, which TRW again opposed. 

TRW appealed the district court’s grant of plaintiffs’ renewed motion for summary 

judgment. In its appeal, TRW again argued that the renewed motion for summary judgment was 

untimely and that the district court lacked jurisdiction to decide plaintiffs’ ERISA claim.

We consolidated TRW’s appeals in the separate cases of: (1) the district court’s order 

granting plaintiffs’ renewed motion for summary judgment, which determined that TRW’s breach 

of the CBA also amounted to an ERISA violation, and permitting plaintiffs to resubmit their 

motion for attorney’s fees; and (2) the district court’s order in the separate action determining that 

the arbitrator did not exceed his authority when he ordered TRW to reinstate the enhanced health 

care benefits that it provided between 2007 and 2012. In March 2019, we concluded that we did 

not have appellate jurisdiction over the ERISA attorney’s fees issue because “[a] mere 

determination of liability under ERISA, without further decision about entitlement to relief, does 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

7

not constitute . . . a final judgment.” UAW Int’l v. TRW Auto. U.S. LLC, 766 F. App’x 186, 194 

(6th Cir. 2019). The district court’s decision would be final only when the court determined the 

amount of attorney’s fees to be awarded, which had not occurred yet. Id. But we did have appellate 

jurisdiction over the district court’s order denying TRW’s motion to partially vacate the arbitration 

award. We determined that “the arbitrator did not arguably construe or apply the 2002 CBA when 

he ordered TRW to reinstate the enhanced healthcare coverage that it began providing in 2007, 

and he exceeded his authority by determining that the parties modified the terms of the 2002 CBA.” 

Id. at 197. Accordingly, the district court erred in enforcing this part of the award and the case 

was remanded back to the district court for further proceedings. 

On remand, in April 2019, plaintiffs filed a supplemental motion for additional attorney’s 

fees. As with the earlier motions for attorney’s fees, TRW also opposed this motion. The district 

court referred the two pending motions for attorney’s fees to a magistrate judge. In August 2019, 

the magistrate judge issued a report and recommendation recommending that the requests be 

denied. The magistrate reasoned that plaintiffs’ contention that the arbitrator determined the CBA 

issues without addressing the ERISA attorney’s fees issue was a “distinction [that] evaporates 

under scrutiny” because the CBA claim encompassed the ERISA claim. The magistrate 

recommended that the district court conclude that plaintiffs are therefore “bound by the arbitrator’s 

determination that each side will bear its own fees through the date of the arbitration award.” The 

magistrate also recommended denying plaintiffs’ request for attorney’s fees incurred since 

arbitration concluded. The magistrate reasoned that plaintiffs reopened the case to relitigate the 

attorney’s fees issue that the arbitrator had already decided, plaintiffs could have raised the ERISA 

issues with the arbitrator but elected not to, and plaintiffs at most had achieved “trivial success on 

the merits” or a “purely procedural victor[y]” when the district court granted their renewed motion 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

8

for summary judgment because TRW conceded it violated ERISA and opposed the motion on only 

procedural grounds.

The district court in September 2019 declined to fully follow the magistrate judge’s 

recommendation and instead granted in part plaintiffs’ motions for attorney’s fees. The court 

declined to award any ERISA attorney’s fees and costs incurred through the date of the arbitration 

award because “the ERISA claim was not addressed prior to or at arbitration.” The court further 

reasoned that plaintiffs: “(1) did not move to vacate the arbitrator’s decision denying attorney fees; 

(2) voluntarily dismissed their appeal of th[e] [c]ourt’s order compelling arbitration . . . ; and 

(3) did not otherwise challenge the denial of an award of attorney fees and costs for Plaintiffs’ 

expenses related to the arbitration.” But the court granted plaintiffs’ request for attorney’s fees 

and costs related to their ERISA claim incurred after the arbitration award. The court referred to 

its January 2018 conclusion that the arbitration award did not address plaintiffs’ ERISA vesting

claim and that they could therefore seek attorney’s fees under § 1132(g) at the district court. 

Finally, the court concluded that plaintiffs were entitled to attorney’s fees not just for the efforts 

related to filing the renewed motion for summary judgment but also for an array of other activity 

since the arbitration award was issued in April 2013, including the filings in the previous appeal 

before us. Although the court acknowledged that some of the entries did not contain detail relating 

to the issue of whether TRW violated ERISA, the court found that all of the billed hours had some 

bearing on “[p]laintiffs’ efforts to pursue relief caused by those ERISA violations.” The court 

awarded plaintiffs a total of $183,300.91. 

TRW and plaintiffs both appeal the district court’s decision. TRW appeals the district 

court’s grant of summary judgment on the ERISA vesting claim and the grant of ERISA attorney’s

9

fees under § 1132(g) incurred after the date of the arbitration, while plaintiffs appeal the district 

court’s denial of attorney’s fees incurred through the date of the arbitration. 

The district court’s summary judgment and attorney’s fee orders were beyond its power. 

The district court lacked the authority to rule on those matters because the ERISA vesting claim 

and ERISA attorney’s fee claim under 29 U.S.C. § 1132(g) were both subject to mandatory 

arbitration under the CBA, allowing only limited court review for issues of legality or enforcement. 

Once the district court ordered all claims subject to mandatory arbitration, the arbitrator had sole 

authority to determine the merits and issue a remedy, and the district court had no power to secondguess the arbitrator’s decision. 

The 2002 CBA mandated arbitration of both the ERISA vesting claim and ERISA statutory 

attorney’s fees claim, for the following reasons. 

We begin with background principles. The Supreme Court has held that a CBA may be 

read to compel arbitration of certain statutory claims only if the agreement is clear and 

unmistakable. See 14 Penn Plaza LLC v. Pyett, 556 U.S. 247, 274 (2009). As to ERISA, our 

precedent specifies that “ERISA claims can be the subject of arbitration pursuant to a CBA, even 

without an express listing of ‘ERISA claims’ in the arbitration provision, because the genesis of 

the claim is the agreement, not a statute.” VanPamel v. TRW Vehicle Safety Sys., Inc., 723 F.3d

664, 669 (6th Cir. 2013). In such cases, the ERISA claim is “derived, at least in part, on the rights 

a plaintiff may have under a collective bargaining agreement.” Id.

First, the language of the CBA reveals that the parties intended for all claims, including 

ERISA claims, to be subject to mandatory arbitration because the ERISA claims required 

interpretation of the CBA. Section 4.1 of the CBA declares that the “arbitration procedures 

provided herein are adequate to provide fair and final determination of all grievances which may 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

10

arise out of the employment relationship during the term of this Agreement” and that arbitration 

“shall be the exclusive remedy for the enforcement by them of any claim against the Company.” 

The CBA defines the term “grievance” as any dispute over “claims that the company has failed to 

carry out a provision of the Agreement and which involves a question concerning the interpretation 

or application of or compliance with this Agreement . . . .” The parties thus agreed that arbitration 

would be the exclusive remedy for any dispute requiring interpretation or application of the CBA. 

Also, plaintiffs’ ERISA vesting claim alleges that the CBA contains an “employee welfare benefit” 

plan, whose breach by TRW violated ERISA.

The district court determined that plaintiffs were attempting to enforce benefits allegedly 

provided under the CBA. Therefore, plaintiffs’ claims required interpretation and application of 

the CBA, and were required to be arbitrated. This included the ERISA claims, because the court 

determined that plaintiffs were “essentially seeking rights that arise out of the CBA and not an 

independent ERISA plan.” The court noted that if the “ERISA claims did not require interpretation 

of the CBA, the Court would be inclined to stay litigation on those claims until the arbitrable 

claims are resolved.” But, plaintiffs presented no claims that were independent of the CBA, so the 

court did not issue a stay. Accordingly, plaintiffs were required to arbitrate the ERISA claims.

Additionally, the ERISA statutory claim under § 1132(g)(1) 1seeking attorney’s fees was 

subject to mandatory arbitration alongside the ERISA vesting claim, because the statutory claim 

also arose out of the CBA. To obtain attorney’s fees under the statute, plaintiffs needed to achieve 

“some degree of success on the merits” of the underlying ERISA vesting claim. Hardt v. Reliance 

1 29 U.S.C. § 1132(g)(1) provides: 

(g) Attorney’s fees and costs; awards in actions involving delinquent contributions

(1) In any action under this subchapter (other than an action described in paragraph (2)) by a 

participant, beneficiary, or fiduciary, the court in its discretion may allow a reasonable attorney’s

fee and costs of action to either party. 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

11

Standard Life Ins. Co., 560 U.S. 242, 254 (2010) (quotation omitted). Demonstrating success on 

the merits did not mean plaintiffs were automatically entitled to attorney’s fees, however, because 

the attorney’s fee provision is discretionary.

2

 See id. Nevertheless, to achieve some success on 

the merits, plaintiffs had to show that TRW committed an ERISA violation by breaching the CBA. 

The attorney’s fee claim is “derived, at least in part” on plaintiffs rights under the CBA, and its

“genesis” is accordingly the CBA. See VanPamel, 723 F.3d at 669–70.

Moreover, plaintiffs waived any objection to mandatory arbitration of their ERISA claims 

because they voluntarily dismissed their appeal of the district court’s order to compel arbitration. 

In their appeal before this Court, plaintiffs specifically objected to being required to arbitrate their 

ERISA claims, arguing that because arbitrators rarely award fees, plaintiffs are unlikely to recover 

attorney’s fees under § 1132(g) of the ERISA statute at arbitration. However, plaintiffs chose

voluntary dismissal of their appeal after receiving a favorable outcome from the arbitrator. The 

dismissal marked plaintiffs’ consent to have all claims resolved by the arbitrator, who had sole 

authority under the CBA to decide the merits and issue a remedy. 

Second, the LMRA claim alleging breach of contract and the ERISA vesting claim at issue 

here were subject to mandatory arbitration because the genesis of the ERISA claim was the 

agreement. Prior to the arbitration hearing, both parties agreed to have the arbitrator first determine 

whether TRW breached the CBA when it attempted to replace the employees’ health insurance 

coverage with HRAs. Plaintiffs contend that because the parties stipulated that the arbitrator would 

2

In this Circuit, courts deciding whether to award ERISA attorney’s fees also consider (1) the degree of the opposing 

party’s culpability or bad faith; (2) the opposing party’s ability to satisfy an award of attorney’s fees; (3) the deterrent 

effect of an award on other persons under similar circumstances; (4) whether the party requesting fees sought to confer 

a common benefit on all participants and beneficiaries of an ERISA plan or resolve significant legal questions 

regarding ERISA; and (5) the relative merits of the parties’ positions. Sec’y of Dep’t of Labor v. King, 775 F.2d 666, 

669 (6th Cir. 1985); Wallace v. Oakwood Healthcare, Inc., 954 F.3d 879, 899 (6th Cir. 2020) (affirming the viability 

of the King factors after the decision in Hardt). As a result, unlike the ERISA vesting claim, the attorney’s fee inquiry 

may not always rise and fall with the underlying contractual claim.
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

12

decide issues of “contract interpretation and breach,” the arbitrator therefore did not decide the 

ERISA claims. However, because plaintiffs’ LMRA and ERISA vesting claims turned on the 

CBA provisions guaranteeing certain health insurance benefits, a finding that TRW breached those 

provisions necessarily resolved those claims. We have previously held that violations of health 

insurance benefits provided in a collective bargaining agreement also qualify as violations of 

welfare benefit plans under ERISA. Armistead v. Vernitron Corp., 944 F.2d 1287, 1298 (6th Cir. 

1991) (abrogated on other grounds). This is confirmed by plaintiffs’ own demand for remedies 

before the arbitrator, where they argued that TRW’s same action (replacing Humana coverage with

HRAs) was both a breach of “the governing CBAs” and “violated ERISA.” The arbitrator’s 

decision that TRW breached the CBA meant that TRW also violated rights vested under ERISA. 

TRW even acknowledged the arbitrator’s determination that it violated ERISA by not presenting 

any substantive opposition to plaintiffs’ renewed motion for summary judgment on the ERISA 

vesting claim. The district court, agreeing with the magistrate judge, similarly concluded that the 

arbitrator’s decision resolved the ERISA vesting claim “because a breach of the CBA with respect 

to insurance benefits also constitutes a violation of ERISA.”

Once the arbitrator finds a merits violation, the parties are responsible for raising any 

remedy issues in their remedy demands during arbitration. Plaintiffs argue that the attorney’s fee 

issue is not subject to arbitration because the dispute was not yet ripe at the time of the district 

court order mandating arbitration. This argument is without merit. The CBA provides that the 

arbitration procedures will be the exclusive remedy for any claims against TRW. The arbitrator 

was therefore authorized to decide the merits of the claims and fashion an appropriate remedy 

based on that decision. Remedy issues directly stem from the merits of the dispute and it would 

be anomalous for the arbitrator not to address those issues after making a merits determination. 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

13

The Supreme Court has expressed a strong preference that arbitrators be the ones to determine 

remedy issues, particularly in the context of labor-management disputes. United Steelworkers v. 

Enter. Wheel & Car Corp., 363 U.S. 593, 596-97 (1960). The parties do not have to return to the 

district court once a merits violation is found just to seek permission to present “ripe” remedy 

issues to the arbitrator. Plaintiffs’ position, presented without any supporting legal authority,

would lead to an untenable result where the arbitrator performs factfinding but the district court 

issues the remedy. Not only would this contradict the CBA’s declaration that arbitration is the 

exclusive remedy for any dispute, but it would also defeat the purpose of arbitration if the parties 

still have to litigate remedy issues in federal court. 

In addition, plaintiffs sought ERISA attorney’s fees in their federal complaint; the district 

court then compelled the entire “dispute” to arbitration and dismissed the case without prejudice. 

Plaintiffs then subjected their § 1132(g) ERISA claim for attorney’s fees to binding arbitration by 

raising it in their remedy demand. Plaintiffs’ argument in passing at the arbitration hearing that 

they were not seeking ERISA attorney’s fees from the arbitrator, and instead would seek them in 

federal court, is unavailing. Once plaintiffs presented the fee request to the arbitrator in the 

“remedies sought” portion of the arbitration demand, they consented to the arbitrator’s authority 

to determine whether or not to award attorney’s fees. Plaintiffs requested that if they received a 

favorable outcome at summary judgment, the arbitrator should “[d]irect TRW to pay the costs and 

expenses and attorney’s fees of UAW, class counsel, and the retirees . . . incurred in connection 

with the litigation and the arbitration proceedings, under 29 U.S.C. § 1132(g)(1) . . . .” Plaintiffs 

cannot claim they did not want the arbitrator to award attorney’s fees while also requesting relief 

under the ERISA attorney’s fee provision. The arbitrator declined to award fees under the statute, 

and plaintiffs are bound by that determination. By consenting to arbitrating the claim, plaintiffs 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

14

waived any objection to the arbitrator’s authority to issue a final decision on the merits. See 

Nationwide Mut. Ins. Co. v. Home Ins. Co., 330 F.3d 843, 846 (6th Cir. 2003). Plaintiffs cannot 

thereafter go to the district court for a second bite at the apple simply because they disagree with 

the outcome.

Finally, the parties’ stipulations prior to the arbitration hearing reveal their acceptance of 

the arbitrator’s authority to decide both the ERISA vesting claim and § 1132(g) attorney’s fee 

claim. The parties did not, as plaintiffs argue, limit the arbitrator’s decision to only contractual 

issues. The parties’ pre-hearing stipulation was that they would submit cross motions of summary 

judgment to the arbitrator limited to the issues of “contract interpretation and breach.” The narrow 

scope of the summary judgment motions did not prevent the arbitrator from deciding other issues. 

In fact, the parties stipulated that each “reserve[d] the right to present further evidence to address 

issues unresolved by the Arbitrator’s decision on the motions, including factual disputes; ERISA 

issues; etc.” This reveals that the parties contemplated having the arbitrator decide any ERISA 

issues that were not resolved by the summary judgment motions. It cannot be read to reserve a 

right to present issues before the district court. Because all of plaintiffs’ claims were subject to 

mandatory arbitration, including the ERISA claims, this means the ERISA claims were either 

resolved by the arbitrator at summary judgment or should have been presented to the arbitrator 

under this stipulation. If plaintiffs believed there were outstanding ERISA issues, they should 

have presented them to the arbitrator after the summary judgment determination. That they had 

the opportunity to raise the issue and chose not to suggests that plaintiffs believed that the 

arbitrator’s decision resolved all of the claims in their favor. When they did not get the remedy 

they desired, they raised these motions to overturn the arbitrator’s judgment. 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

15

Because the CBA mandated arbitration of plaintiffs’ ERISA and attorney fee claims, and 

the district court accordingly compelled arbitration, the court lacked the authority to subsequently 

rule on these issues, apart from the limited power to vacate and the power to resolve issues of 

compliance with the arbitrator’s award. 

The Supreme Court has cautioned that courts have no authority to second-guess an 

arbitrator’s decision, particularly with respect to labor-management disputes. Enter. Wheel, 363 

U.S. at 596-97. The Court has firmly rejected judicial interference with the arbitrator’s award, 

writing that “courts . . . have no business weighing the merits of the grievance . . . .” United 

Steelworkers v. Am. Mfg. Co., 363 U.S. 564, 568 (1960). “When the judiciary undertakes to 

determine the merits of a grievance under the guise of interpreting the grievance procedure of 

collective bargaining agreements, it usurps a function which under that regime is entrusted to the 

arbitration tribunal.” Id. at 569.

We have reinforced these instructions with our own precedent, holding that “where a labor 

agreement mandates arbitration, courts must order [a] resort to private settlement mechanisms 

without dealing with the merits of the dispute.” Armco Employees Independent Federation, Inc. 

v. Armco Steel Co. L.P., 65 F.3d 492, 496 (6th Cir. 1995) (quotation omitted). “[D]istrict courts 

are not empowered to perform factfinding or second-guessing,” particularly with respect to labormanagement conflicts. Id. The arbitrator has sole authority to conduct factfinding and “is the only 

entity empowered to fashion a proper remedy.” Id. at 497, 498. We reiterated this principle more 

recently, noting that “[t]he ‘proper approach,’ therefore, is for courts to refuse to review the merits 

of an arbitration award.” Brotherhood of Locomotive Eng’rs v. United Transp. Union, 700 F.3d 

891, 900 (6th Cir. 2012) (quoting Enter. Wheel, 363 U.S. at 596). Once the factfinding is complete 

and a violation is found, “an arbitrator, not a court, can then decide whether the Union’s attorney’s
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

16

fees should be paid by [the employer].” Armco, 65 F.3d at 497-98. While a court does have 

authority to review an arbitrator’s decision “to determine whether an arbitrator’s award exceed the 

limits of his contractual authority . . . , it may not review the merits of an arbitration award.” 

Timken Co. v. Local Union No. 1123, United Steelworkers, 482 F.2d 1012, 1014 (6th Cir. 1973). 

Plaintiffs’ attempts to distinguish Armco are unconvincing. In Armco, we affirmed 

dismissal because the district court lacked the authority to decide the merits of the plaintiffs’ 

arbitrable claims where additional factfinding by the arbitrator was required. Armco, 65 F.3d at 

497-98. The arbitrator had issued an award in favor of the employees requiring the defendant to

maintain proper levels of staffing under certain circumstances. Id. at 494-95. A dispute arose 

post-arbitration as to whether the company violated the arbitrator’s award because it was 

ambiguous whether certain types of job listings satisfied the arbitrator’s award. Id. at 495, 498. 

We held that additional factfinding was necessary to determine whether the company actually did 

violate the award. Id. at 497-98. Only the arbitrator had the authority to conduct that factfinding 

and decide the merits of plaintiffs’ claim because it required interpretation of the parties’ CBA. 

Id. Moreover, because the parties’ CBA provided for arbitration as the exclusive remedy for any 

dispute, the district court had no authority to adjudicate the merits or craft any sort of remedy. Id. 

at 498. Here, plaintiffs contend that they are not suing to enforce an arbitral award or for breach 

of contract, so Armco does not apply. This argument is without merit. Just as in Armco, the 

arbitrator in this case had sole authority to decide the merits of the ERISA vesting and statutory

claims because the claims required interpretation of CBA’s benefit provisions. That was the basis

for the district court’s order compelling the LMRA and ERISA claims to arbitration in the first 

place. Thus, only the arbitrator could issue a final determination as to whether TRW violated 

rights vested under ERISA by breaching the CBA.
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

17

Additionally, because the CBA here declared that arbitration was to be the exclusive 

remedy for any dispute between the parties arising from the agreement, the arbitrator was the only 

entity empowered to craft a remedy, just as in Armco. 65 F.3d at 498. This is consistent with the 

Supreme Court’s instruction that “where it is contemplated that the arbitrator will determine 

remedies for contract violations that he finds, courts have no authority to disagree with his honest 

judgment in that respect.” United Paperworkers Int’l Union v. Misco, Inc., 484 U.S. 29, 38 (1987). 

Courts “are not authorized to reconsider the merits of an [arbitration] award.” Id. at 36. 

Furthermore, as we noted in Armco, this authority to decide the merits and fashion a remedy means 

that the arbitrator, not the district court, is the one who decides whether the defendant should pay 

the plaintiffs’ attorney’s fees. 65 F.3d at 498. It is immaterial that the attorney’s fee issue here

arose under the ERISA statute, while the fee request in Armco was based on an allegation of bad 

faith, because both fee requests turned on the merits of the underlying claim (here the vesting 

claim) and only the arbitrator had authority to decide the merits. Id. at 495. 

The district court could not “reserve” authority for itself by dismissing the claims without 

prejudice in its order compelling arbitration. The court’s declaration that any party could file a 

motion to reopen the case after arbitration does not alter the district court’s circumscribed authority 

where a labor agreement mandates arbitration. No caselaw supports plaintiffs’ position that a 

district court can reserve authority to review an arbitrator’s award simply by dismissing claims 

without prejudice. If this were the law, any party that was unhappy with the arbitrator’s award 

could seek a better outcome at the district court, so long as the claims were dismissed without 

prejudice. This would contradict the Supreme Court’s strongly stated preference that labormanagement disputes be resolved by arbitrators, not courts. See Enterprise Wheel, 363 U.S. at 

596-98. Arbitrators are able to “settle disputes at the plant level” that require “knowledge of the 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

18

custom and practices of a particular factory or of a particular industry as reflected in particular 

agreements.” Id. at 596.

 Of course, the district court could have entertained a timely motion to vacate or modify 

the award, on the very limited grounds applicable to such motions. But plaintiffs did not bring a 

timely motion to vacate or modify the award. In their post-arbitration briefing on the attorney’s 

fee request before the district court, plaintiffs admitted that they were not seeking to vacate or 

modify the arbitrator’s award. The arbitrator’s award decided the ERISA attorney’s fees issue, so 

the only way to obtain attorney’s fees would be for plaintiffs to challenge the award itself. If 

plaintiffs were unhappy with the award of no attorney’s fees, they should have filed a motion to

vacate or modify the award. Absent such a motion, the district court had no authority to alter the 

arbitrator’s award. Armco, 65 F.3d at 496. A party may file a motion to vacate or modify an 

arbitrator’s award under Section 301 of LMRA, 29 U.S.C. § 185, which authorizes courts to 

enforce or vacate labor arbitration awards. See, e.g., Champion Int’l Corp. v. United Paperworkers 

Int’l Union, 779 F.2d 328, 329, 332 (6th Cir. 1985). Courts are authorized to vacate arbitration 

awards where the award does not “draw[] its essence from the collective bargaining agreement.” 

Enter. Wheel, 363 U.S. at 597. An arbitrator’s award “fails to derive its essence from the 

agreement when (1) it conflicts with express terms of the agreement; (2) it imposes additional 

requirements not expressly provided for in the agreement; (3) it is not rationally supported by or 

derived from the agreement; or (4) it is based on general considerations of fairness and equity 

instead of the exact terms of the agreement.” Dallas & Mavis Forwarding Co. v. Gen. Drivers, 

Local Union No. 89, 972 F.2d 129, 134 (6th Cir. 1992) (internal quotation marks omitted) (citation 

omitted). Plaintiffs did not move to vacate or modify the award, so the district court had no basis 

to review the award.
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

19

Even if we treat the motions for summary judgment and attorney’s fees as a challenge to

the award under the LMRA, the district court still lacked authority to hear the dispute because the 

challenge was not timely made. In a LMRA § 301 challenge, timeliness “is to be determined, as 

a matter of federal law, by reference to the appropriate state statute of limitations.” UAW Int’l v. 

Hoosier Cardinal Corp., 383 U.S. 696, 704–05 (1966). With respect to Michigan law, Michigan’s 

Uniform Arbitration Act, which went into effect in 2013, is closely analogous to a § 301 action 

involving a dispute over a labor CBA. See Mich. Comp. Laws § 691.1703. Based on this statute, 

challenges to an arbitration award brought pursuant to § 301 of the LMRA in Michigan are 

therefore subject to a 90-day limitations period. See id. § 691.1703(2). Plaintiffs filed their 

renewed motion for summary judgment and first motion for attorney’s fees approximately six 

months after the arbitration award was issued. It makes no difference that plaintiffs filed their 

motions for summary judgment and attorney’s fees fourteen days after voluntarily dismissing their 

appeal of the motion to compel arbitration, because under the Michigan statute the limitations 

period runs starting from the date the “moving party receives notice of the award.” Id. Thus, 

plaintiffs’ motions were an untimely challenge to the arbitration award.

Furthermore, the district court had no authority to grant plaintiffs’ motions because the 

reopened issues did not relate to enforcement of the arbitrator’s award. Parties may seek judicial 

review to confirm or enforce arbitration awards. Enter. Wheel, 363 U.S. at 597. Courts can enforce 

compliance with arbitration awards but cannot go beyond the award to decide issues that the 

arbitrator did not decide. Cleveland Paper Handlers v. E.W. Scripps Co., 681 F.2d 457, 459-60 

(6th Cir. 1982) (citing Enter. Wheel, 363 U.S. at 599). Here, the ERISA dispute was not related 

to enforcement of the arbitrator’s award, because the arbitrator had determined that TRW had 

breached the CBA but did not award plaintiffs attorney’s fees under § 1132(g). At best, plaintiffs’
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

20

request for attorney’s fees was a challenge to the award, not a request enforce compliance with the 

award.

Although the district court did have authority to review plaintiffs’ subsequent timely 

motions to enforce the arbitrator’s award, the resolution of those matters did not give the court the 

authority to determine the merits of the ERISA claims and alter the award. After the arbitrator 

issued the award ordering TRW to make plaintiffs whole, a dispute arose between the parties as to

the appropriate relief for nine of the retirees. The parties raised the dispute before the district court, 

which had authority to enforce the award under Section 301 of the LMRA, and the court found in 

favor of plaintiffs. The resolution of this dispute could not serve as a basis for the court’s later 

award of attorney’s fees to plaintiffs, because a prevailing party on a motion to enforce an 

arbitration award is not entitled to attorney’s fees absent an authorizing statute, contractual 

provision, or a showing of bad faith. See Monroe Auto Equip. Co. v. UAW, 981 F.2d 261, 269-70 

(6th Cir. 1992). Indeed, the district court did not even cite plaintiffs’ successful motion to enforce 

the arbitration award as a basis for the fee award at issue. TRW’s agreement to litigate these 

discrete enforcement issues before the court did not mean TRW consented to the court’s attempt 

to second-guess the arbitrator. Such consent would be ineffective regardless, because the court 

had no authority to review the ERISA claims in the first place. Additionally, TRW consistently 

opposed plaintiffs’ motions to reopen the ERISA claims on the grounds that the district court 

lacked “jurisdiction” to do so because the issues could only be resolved by the arbitrator. Finally, 

there is no evidence indicating that “TRW continued to violate ERISA” after the arbitration, as 

plaintiffs allege on appeal; therefore this argument does not provide the court a valid basis to 

review the ERISA claims. Thus, none of these enforcement issues authorized the district court to 

decide the ERISA claims and award fees.
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

21

Finally, in any event, the arbitrator did decide the ERISA vesting claim and § 1132 claim 

for attorney’s fees in his award. The district court’s primary justification for issuing the summary 

judgment and attorney’s fees orders in plaintiffs’ favor was that the arbitrator did not decide the 

ERISA claims. However, this conclusion collapses in light of our reasoning above. The 

relationship between the ERISA and LMRA claims and the parties’ arguments during arbitration 

reveals that the arbitrator did in fact decide the ERISA claims. His decision that TRW breached 

the CBA meant that TRW also committed an ERISA violation, as the district court itself 

recognized and TRW admitted by not presenting any substantive opposition to plaintiffs’ renewed 

motion for summary judgment. The arbitrator also declined to award attorney’s fees under § 

1132(g) after plaintiffs specifically asked him to do so. Once the arbitrator determined that TRW 

violated the CBA, he necessarily resolved the merits of both ERISA claims. “Arbitrators have no 

obligation to the court to give their reasons for an award.” Enter. Wheel, 363 U.S. at 598. After 

deciding that TRW breached the CBA, the arbitrator was simply required to fashion an appropriate 

remedy. Armco, 65 F.3d at 498. He had no obligation to disclose whether or not the award was 

granted in part because TRW’s breach constituted a violation of ERISA. Enter. Wheel, 363 U.S. 

at 598. The ERISA claim was submitted to and decided by the arbitrator, leaving no room for any 

district court review on the merits. If the parties felt that there were unresolved ERISA issues, 

they should have presented those to the arbitrator consistent with their pre-hearing stipulations. 

The district court’s disagreement with the arbitrator’s decision did not confer authority for it to 

second-guess the arbitrator. Armco, 65 F.3d at 496. Plaintiffs cannot recover the post-arbitration 

attorney’s fees they request because the arbitrator already determined that they were not entitled 

to recover on claims arising out of the CBA. The arbitrator had sole authority to fashion a remedy, 
Case Nos. 19-2252/2262, UAW Int’l v. TRW Automotive

22

and absent a timely motion to vacate or modify the award, the court could not alter the award to 

grant plaintiffs’ request for attorney’s fees. Id. 

However, even if plaintiffs are correct that the arbitrator’s award did not address the ERISA 

claims, it makes no difference because the district court still had no authority to decide those 

claims. The district court properly ordered all claims, including the ERISA claims, subject to 

mandatory arbitration. Plaintiffs waived any objection to that order when they dropped their 

previous appeal before this Court. The district court could not go back and decide the merits of 

the claims once arbitration of those claims was compelled. See Enter. Wheel, 363 U.S. at 599.

Once those issues were delegated to the arbitrator, the court had no authority to adjudicate issues 

that the arbitrator did not reach. Cleveland Paper Handlers, 681 F.2d at 460. The arbitrator had 

sole authority to conduct factfinding, adjudicate the merits, and issue a remedy, if any, on the basis 

of the ERISA vesting claim and associated request for attorney’s fees. Thus, regardless of whether 

the arbitrator decided the ERISA issue, the court still lacked the authority to grant plaintiffs’

motions for renewed summary judgment and attorney’s fees. 

Accordingly, because the district court lacked the authority to award fees, the award is 

reversed, and we do not reach any issues about the proper scope of fees if the district court did 

have the authority to grant them. 

For the foregoing reasons, we reverse the judgment of the district court.
