Firestone Deference Extends to LMRA § 301 Trust-Agreement Interpretation; MPPAA § 1401 Bars Pre-Arbitration Withdrawal-Date Declaratory Claims

1. Introduction

This appeal sits at the intersection of (i) a multiemployer pension plan’s power to police “adverse selection” behavior by participating employers and (ii) Congress’s insistence that withdrawal-liability disputes proceed first through arbitration. Penske Truck Leasing, L.P. (“Penske”) participated in the Central States, Southeast and Southwest Areas Pension Plan (the “Plan”) for multiple bargaining units, including Teamsters Local No. 745 (Dallas, Texas). Central States became concerned that Penske was attempting to align expiration dates across ten collective-bargaining agreements to convert what could be multiple withdrawal events (partial then complete withdrawal) into a single complete withdrawal, potentially reducing liability by “tens of millions of dollars.”

During negotiations, Central States threatened to terminate Local 745’s participation unless Penske agreed that a 2022 withdrawal of Local 745 would be treated as a 2021 withdrawal. Penske sued, obtained a temporary restraining order (later vacated), and ultimately lost on summary judgment. Central States counterclaimed seeking a declaration fixing Local 745’s effective withdrawal date, but the district court dismissed that counterclaim as premature under 29 U.S.C. § 1401’s mandatory arbitration requirement.

The Seventh Circuit affirmed on all issues, using the case to clarify two doctrinal points of broad practical significance: (1) when a trust agreement grants trustees discretionary and final interpretive authority, courts apply Firestone-style deference even in an LMRA § 301 contract action and not only in benefits-denial litigation; and (2) MPPAA § 1401 bars federal-court adjudication of withdrawal-date disputes until the statutory arbitration pathway has been followed.

2. Summary of the Opinion

3. Analysis

3.1 Precedents Cited

The opinion is unusually precedent-dense, drawing on Supreme Court guidance on multiemployer withdrawal liability, ERISA trust-law deference, and statutory exhaustion, as well as circuit precedent on § 1401 arbitration.

A. Multiemployer plans and the rationale for withdrawal liability

• Concrete Pipe & Products of California, Inc. v. Construction Laborers Pension Trust for Southern California: used for foundational description of multiemployer plan mechanics and portability of pension credit; also referenced later to note abrogation “on other grounds” regarding earlier § 1394(b) discussion in other circuits. The Seventh Circuit uses it as the conceptual baseline for why multiemployer plans exist and why withdrawal liability matters.
• Milwaukee Brewery Workers' Pension Plan v. Joseph Schlitz Brewing Co.: supplies the “death spiral” policy narrative (withdrawals → increased costs → more withdrawals) and the key statutory rule that liability is generally measured as of “the last day of the plan year preceding the year during which the employer withdrew.”
• Artistic Carton Co. v. Paper Industry Union-Management Pension Fund: cited for the withdrawal-liability framework and, later, for the standard of judicial review after arbitration under § 1401(b)(2).
• Chicago Truck Drivers, Helpers & Warehouse Workers Union (Independent) Pension Fund v. CPC Logistics, Inc. and Supervalu, Inc. v. United Food & Commercial Workers Unions & Employers Midwest Pension Fund: cited to explain employers’ incentives to minimize liability and plans’ incentives to protect funding; they contextualize Central States’ concern about “manipulating” withdrawal timing.
• M & K Employee Solutions, LLC v. Trustees of the IAM Nat'l Pension Fund: used to illustrate the complexity of actuarial assumptions and measurement rules and to reinforce that withdrawal-liability calculation is a specialized statutory domain.

B. Deference to trustees’ interpretation of trust instruments

• Firestone Tire & Rubber Co. v. Bruch: provides the canonical rule: if plan documents confer discretionary authority to construe disputed terms, courts review for reasonableness rather than de novo. The Seventh Circuit treats this as the controlling standard despite the LMRA § 301 procedural vehicle.
• Conkright v. Frommert: reinforces Firestone’s trust-law grounding and the deference owed where discretionary interpretive power is granted.
• Schneider Moving & Storage Co. v. Robbins and Central States, Southeast & Southwest Areas Pension Fund v. Central Transport, Inc.: crucial for extending trustee-interpretation deference beyond benefits-denial settings; both involved Central States and audits, and both deferred to trustees under the same (or materially similar) trust language.
• Seventh Circuit and sister-circuit Central States cases—Manny v. Central States, Southeast & Southwest Areas Pension & Health & Welfare Funds, Exbom v. Central States, Southeast & Southwest Areas Health & Welfare Fund, Oldenburger v. Central States Southeast & Southwest Areas Teamster Pension Fund, Bagsby v. Central States, Southeast & Southwest Areas Pension Fund—are marshaled to show that deference is an established feature of this plan’s governance.
• Borntrager v. Central States Southeast & Southwest Areas Pension Fund: especially influential because it upheld Central States’ expulsion authority under a similar “adverse selection” rule and gave the trustees’ construction “significant weight.” The Seventh Circuit uses it as a close analogue to expulsion in response to employer practices that reduce contribution flows.
• Central States, Southeast & Southwest Areas Pension Fund v. Waste Management of Michigan, Inc. and Neuma, Inc. v. AMP, Inc.: invoked by Penske to argue that ambiguity must be found before deference is applied. The court distinguishes them as not addressing discretionary-interpretation clauses and, in Waste Management, as involving an interpretation so unreasonable it failed under either standard.
• Turkiye Halk Bankasi A.S. v. United States and Illinois v. Lidster: cited for a method point—broad language in prior opinions must be read in context—used to neutralize Penske’s reliance on generalized statements about ambiguity analysis.
• Trust-law authorities (Bogert; Restatement (Third) of Trusts): used to justify deference as a trust-law default when a settlor grants interpretive discretion, underscoring Firestone’s trust-law analogy.

C. “Arbitrary and capricious” review and limits of importing ERISA benefits-denial proceduralism

• Van Boxel v. Journal Co. Employees' Pension Trust: used to describe the general posture of arbitrary-and-capricious review—courts uphold reasonable decisions even if they would have decided differently.
• Cerentano v. UMWA Health & Retirement Funds and Speciale v. Blue Cross & Blue Shield Ass'n (and their embedded citations): appear primarily as examples of benefits-denial standards that the court cautions against importing wholesale into an employer-expulsion dispute.
• Halpin v. W.W. Grainger, Inc.: cited to highlight statutory/regulatory “full and fair review” requirements for benefits determinations—requirements absent here.
• Board of Trustees of Watsonville Frozen Food Welfare Trust Fund v. California Cooperative Creamery and In re Marchiando: used to explain why Central States owes fiduciary duties to participants/beneficiaries, not to contributing employers, weakening Penske’s attempt to impose heightened diligence duties.
• Original Great American Chocolate Chip Cookie Co. v. River Valley Cookies, Ltd.: a contract-law reminder that parties are not required to act “altruistically” absent fiduciary duty—supporting the court’s acceptance of Central States acting in its own interests.
• Malin v. Hospira, Inc.: cited to caution litigants against misrepresenting the record, linked to the panel’s admonition about loosely accusing opposing counsel of dishonesty.
• Model Rules of Professional Conduct r. 3.3: not a case, but employed to underscore that alleging a knowing misrepresentation to a court is a grave accusation requiring a solid basis.

D. NLRA “status quo” and impasse

• General Service Employees Union, Local No. 73 v. NLRB, NLRB v. Emsing's Supermarket, Inc., NLRB v. Katz: supply the rule that employers must maintain the status quo after contract expiration until agreement or impasse, relevant to Penske’s argument that expulsion would force NLRA violations.
• RiverStone Group v. Midwest Operating Engineers Fringe Benefit Funds and Laborers Health & Welfare Trust Fund for Northern Calif. v. Advanced Lightweight Concrete Co.: used to define “impasse” and to note NLRB primacy on unfair labor practice determinations. The Seventh Circuit uses these to reject the claim that plan expulsion necessarily causes unlawful unilateral change.
• Staffco of Brooklyn, LLC & New York State Nurses Ass'n: distinguished as factually different because it involved assumptions about whether the plan would accept contributions and a finding of no impasse.

E. Mandatory arbitration under 29 U.S.C. § 1401 and limited exceptions

• Banner Industries, Inc. v. Central States, Southeast & Southwest Areas Pension Fund and Robbins v. Admiral Merchants Motor Freight, Inc.: characterize § 1401 as mandatory exhaustion (not jurisdictional, but still required).
• Ross v. Blake: provides the modern constraint: courts may not create equitable exceptions to a statutory exhaustion requirement unless Congress authorizes them. This is pivotal to the court’s refusal to entertain Central States’ efficiency/equity arguments.
• Older exception cases—Central States, Southeast & Southwest Areas Pension Fund v. Slotky, I.A.M. Nat'l Pension Fund Benefit Plan C v. Stockton Tri Industries, Republic Industries, Inc. v. Central Pennsylvania Teamsters Pension Fund—are acknowledged as pre-Ross-era pathways some courts used, but the opinion treats them as narrowed post-Ross.
• RTI Restoration Technologies, Inc. v. Int'l Painters & Allied Trades Industry Pension Fund: cited to show at least one circuit continues to recognize only “rare” exceptions, consistent with Ross’s narrowing.
• On withdrawal-date arbitrability specifically: Central States, Southeast & Southwest Areas Pension Fund v. Bomar Nat'l, Inc., Robbins v. Lady Baltimore Foods, Inc., Warner-Lambert Co. v. United Retail & Wholesale Employee's Teamster Local No. 115 Pension Plan: collectively establish that “withdrawal date” disputes are quintessential § 1401 arbitration issues.
• Central States, Southeast & Southwest Areas Pension Fund v. Rail Terminal Services LLC: persuasive district court authority supporting the conclusion that relabeling the dispute as something else (e.g., contributions/credits) does not avoid § 1401 where the substance is a withdrawal-date determination.
• Central States, Southeast & Southwest Areas Pension Fund v. Safeway, Inc.: provides the “pay now, dispute later” backdrop—employer must pay demanded installments pending arbitration (§ 1401(d)).

3.2 Legal Reasoning

A. Interpreting the Trust Agreement: deference first, not ambiguity first

The opinion’s most clarifying move is methodological. Penske urged a two-step approach: decide ambiguity de novo, then defer only if ambiguous. The Seventh Circuit rejected that framing where the governing instrument explicitly grants interpretive discretion and final authority (Trust Agreement, art. IV, § 17). Under Firestone Tire & Rubber Co. v. Bruch and Conkright v. Frommert, the court’s inquiry becomes whether the trustees’ interpretation is reasonable, not whether the judges can craft a better reading.

This matters because the dispute arose under LMRA § 301 (a contract-based claim), not a benefits denial under ERISA § 502. The court nonetheless extended Firestone-style deference, grounding that extension in (i) Firestone’s reliance on trust-law principles, (ii) trust-law sources recognizing the settlor’s ability to grant binding interpretive authority, and (iii) Central States-specific Supreme Court precedent (Schneider Moving & Storage Co. v. Robbins; Central States, Southeast & Southwest Areas Pension Fund v. Central Transport, Inc.) applying deference outside benefits-denial contexts.

B. Scope of expulsion authority: single bargaining unit expulsion is reasonable

Applying that deference, the court upheld the trustees’ reading of the Expulsion Provision (Trust Agreement, art. IV, § 20) as allowing termination of participation for “one or more” of an employer’s “groups” without affecting other groups. The text expressly states that “rejection/termination of one or more of the Employer’s groups” does not affect the continued participation of other groups. The court acknowledged drafting ambiguity (e.g., references to terminating “an Employer”), but under deferential review ambiguity does not defeat a reasonable trustee interpretation.

C. Uniformity and NLRA arguments rejected

Penske’s § 1394(b) “uniformity” argument failed because the court read § 1394(b) as confined to “plan rules and amendments” concerning the calculation of withdrawal liability (29 U.S.C. §§ 1381–1405), whereas the dispute was about participation termination authority. The court also rejected the notion that “uniform operation” requires identical practical consequences across differently situated employers.

Penske’s NLRA theory—that expulsion would force an unlawful failure to maintain the status quo—was rejected on the premise that expulsion reflected a collapse in negotiations consistent with “impasse” concepts, and because the NLRB retains exclusive authority over unfair labor practice determinations. The court treated Penske’s feared NLRA violation as speculative on this record.

D. “Arbitrary and capricious”: limited procedural demands, no employer-fiduciary duty

Even assuming arbitrary-and-capricious review applied, Penske’s challenges were characterized as “minor quibbles” that tried to import benefits-denial procedural expectations (detailed explanations, structured investigative steps, “full and fair review” analogues) into a contractual expulsion power. The court emphasized that ERISA’s benefits-denial notice-and-review protections (29 U.S.C. § 1133; 29 C.F.R. § 2560.503-1(g)) do not govern this expulsion context.

The court’s fiduciary-duty discussion is practically important: Central States may owe fiduciary duties to participants and beneficiaries, but it owes no fiduciary duty to a participating employer as such. That undercut any attempt to demand employer-protective diligence beyond what the Trust Agreement requires. In contract terms, the plan and the employer are counterparties, each permitted to act in self-interest.

Finally, the panel admonished Penske’s insinuation that Central States’ counsel lied in open court, treating such accusations as serious professional-conduct charges that should not be advanced without evidentiary support.

E. Withdrawal-date declaratory relief must await § 1401 arbitration

On the cross-appeal, the court held Central States’ attempt to obtain a judicial declaration fixing the withdrawal date ran headlong into 29 U.S.C. § 1401(a): “Any dispute … concerning a determination made under sections 1381 through 1399 shall be resolved through arbitration.” Seventh Circuit precedent squarely treats withdrawal-date disputes as arbitrable (e.g., Robbins v. Lady Baltimore Foods, Inc.; Central States, Southeast & Southwest Areas Pension Fund v. Bomar Nat'l, Inc.).

The opinion’s key move is to reject a proposed workaround: Central States argued § 1401 was not triggered because no withdrawal-liability “determination” had yet been made. The court refused to read § 1401 so narrowly, reasoning that it would “hollow out” arbitration by incentivizing strategic races to the courthouse (employers to enjoin assessments; plans to delay assessments). Central States also could not avoid § 1401 by characterizing the dispute as about contributions or pension credit; the court treated the “real question” as when the contribution obligation ended, which is the statutory touchstone of withdrawal concepts (see 29 U.S.C. § 1385(a)(2)).

Although Central States argued the district court was better positioned to interpret its own TRO, the court treated § 1401 exhaustion as controlling, especially in light of Ross v. Blake’s insistence that courts may not craft extra-statutory exceptions to congressionally mandated exhaustion.

3.3 Impact

• Broader reach of Firestone deference: The decision fortifies a plan-drafting strategy: explicit discretionary-and-final interpretive clauses (like Trust Agreement art. IV, § 17) can secure deferential review even when the dispute is framed as a contract claim under LMRA § 301 rather than as an ERISA benefits suit. Practically, this reduces the value of semantic repositioning by employers who hope to obtain de novo review.
• Strengthened plan tools against “withdrawal timing” strategies: By upholding unit-by-unit expulsion as a reasonable reading of the Expulsion Provision, the court preserves a potent deterrent against employers’ attempts to restructure bargaining-unit arrangements in ways perceived to threaten plan funding. The opinion does not decide that Penske acted improperly; it holds the plan may act to protect itself within the Trust Agreement’s bounds.
• Reinforced arbitration gatekeeping under § 1401: The opinion warns both plans and employers against end-runs around the MPPAA’s “arbitrate first” architecture. Courts are likely to scrutinize the substance of claims (withdrawal date, contribution obligation end date) rather than their labels (credits, contribution handling, declaratory relief).
• Litigation conduct signal: The panel’s discussion of unsupported accusations of attorney dishonesty is a cautionary note for litigants in high-stakes ERISA/LMRA disputes, where rhetoric can outpace proof.

4. Complex Concepts Simplified

• Multiemployer pension plan: A single pension fund supported by many employers (often in the same industry). Workers can change employers without losing accrued pension credit.
• Withdrawal liability: If an employer stops contributing, it may owe a statutory charge designed to cover its share of unfunded vested benefits so remaining employers/participants are not left short.
• Partial vs. complete withdrawal: A complete withdrawal occurs when the employer permanently stops having an obligation to contribute (29 U.S.C. § 1383(a)). A partial withdrawal can occur when the obligation partially ceases (29 U.S.C. § 1385(a)).
• Measurement date rule (simplified): Withdrawal liability is commonly measured as of the last day of the plan year before the year of withdrawal (Milwaukee Brewery Workers' Pension Plan v. Joseph Schlitz Brewing Co.), meaning the actual calendar date of withdrawal within the year may matter less than which year it falls in.
• Firestone deference: If a plan document gives trustees discretion to interpret it, a court generally asks only whether the trustees’ interpretation is reasonable—not what the court thinks is “best.”
• Arbitrary and capricious review (general idea): A highly deferential review standard; the decision stands if it is rational and supported, even if another decision could also have been reasonable.
• MPPAA § 1401 arbitration (“exhaustion”): Congress required most withdrawal-liability disputes to go to arbitration first. Courts generally cannot decide withdrawal-liability issues until that process is used.
• “Pay now, dispute later”: Even if the employer disputes the bill, it typically must pay installments demanded by the plan pending arbitration (29 U.S.C. § 1401(d)).

5. Conclusion

The Seventh Circuit’s decision delivers two practical rules. First, where a trust agreement grants trustees discretionary and final interpretive authority, courts will apply deferential review to trustees’ plan-document interpretations—even in an LMRA § 301 declaratory-judgment challenge and not only in ERISA benefits-denial litigation. Second, the MPPAA’s arbitration mandate in 29 U.S.C. § 1401 is a firm gatekeeper: disputes over withdrawal dates (and disputes that functionally ask when the contribution obligation ended) must proceed through arbitration before federal courts will adjudicate them, notwithstanding procedural oddities like a vacated TRO. Together, these holdings reinforce plan-governance discretion where contractually granted and preserve Congress’s chosen arbitration-first architecture for withdrawal liability.
