Overview
"It would be difficult for most firms to have a 'team' with significant ERISA litigation experience. Mayer Brown does. We had a solid team that included individuals from various experience levels, and MB staffed the matter well." – Legal 500 2024
“It is a top-notch ERISA law firm.” – Chambers USA 2022
“They know this stuff cold – among the best in the industry. Great to work with.” – Legal 500 2021
To litigate cases about employee benefits requires substantive know-how and the ability to translate arcane concepts into terms that lay judges can understand. Mayer Brown has a thriving ERISA Litigation practice that combines deep experience, skilled advocacy and cutting-edge insights.
Our ERISA litigators are neither benefits lawyers nor litigation generalists—they are full-time litigators who focus on understanding how benefits disputes arise and are adjudicated. As such, our lawyers have been retained to offer counsel on all of the issues that typically arise in litigation or administrative proceedings involving employee benefit plans. We are regularly engaged by plan sponsors and plan administrators, as well as individual and corporate fiduciaries, trustees, custodians, financial institutions and plan service providers, in matters ranging from individual benefit disputes to complex class actions. And we counsel those same clients about how to reduce their risk of being sued in the first place. We have also been preapproved by fiduciary liability carriers to provide defense for their insureds.
The breadth of our experience and our client successes have drawn numerous accolades for both the group and its lawyers from leading publications such as Law360, Legal 500 USA, Chambers USA, The National Law Journal and Best Lawyers. We were named by Law360 as a “Benefits Practice Group of the Year” four years in a row (2019-2022). Our lawyers were also recognized in Band 1 for ERISA Litigation by Chambers USA for each of the last three years (2021-2023), as a 2023 Law360 Rising Star and a 2022 & 2020 Law360 MVP, a Hall of Fame for ERISA Litigation by Legal 500 USA, and as a 2019 “Lawyer of the Year” by Best Lawyers in the category of ERISA Litigation. Additionally, one of our partners was recently named an Employment Law Trailblazer by The National Law Journal, which recognizes lawyers who “continue to make their mark in various aspects of legal work in the areas of employment law.”
When working with Mayer Brown, clients benefit not just from the skills and experience of our ERISA litigators but also from those of our other top-notch professionals. ERISA matters often intersect with investigations by US federal agencies (such as the Department of Labor, the Securities and Exchange Commission and the Internal Revenue Service) and other benefits and tax issues, so we regularly coordinate with our ERISA Fiduciary counseling group, which contributes a deep understanding of ERISA’s regulatory environment, and our firm’s esteemed Securities Litigation & Enforcement and Tax Controversy practices. We also understand that the law is not static and is shaped by litigation strategy. We therefore turn to our elite Supreme Court & Appellate litigation practice when it will benefit our clients. Our Supreme Court & Appellate practice is consistently recognized as one of the best in the United States by Chambers USA and Legal 500 US.
Although our practice covers the full domain of ERISA litigation, here is a sampling of our experience:
Fiduciary
Recent trends have prompted fiduciaries to be sued, often in class actions, under complaints challenging plan investment decisions; plan fee arrangements, including recordkeeping costs and revenue sharing among plan providers; employer stock options; benefits claims denials; and out-of-network healthcare provider billing practices. We have substantial experience in each of these areas. Lawyers in our ERISA Litigation practice are experienced in managing relationships with fiduciary liability carriers and in addressing concerns that arise in such cases. Our favorable results speak for themselves.
Enforcement Actions
Our ERISA Litigation lawyers are practiced in working with the Department of Labor to resolve investigations, audits and enforcement actions, which we have defended on behalf of plans and plan sponsors, advisers and other fiduciaries and service providers. For example, we have represented investment fund advisers in connection with Department of Labor conflict-of-interest challenges, government contractors in Department of Labor investigations over plan fees charged to participants and financial institutions in connection with, among other things, the Department of Labor’s investigation into mutual fund market timing practices, the Department of Labor’s enforcement initiative against cross-trading and in preparing comments to the Department of Labor on its class exemption for passive cross-trading.
Regulatory
The tides of litigation often follow the regulatory agenda of the Department of Labor. Our ERISA Litigation lawyers counsel clients on how to mitigate risks stemming from Department of Labor rulemaking proceedings and have challenged regulatory overreaches in court using the tools of the Administrative Procedure Act. Together with members of our ERISA Fiduciary counseling group, we have also sought formal exemptions and opinion letters from the Department of Labor.
Given this wide range of experience, we are exceptionally well qualified to help clients deal with the controversies that ERISA still generates more than 40 years after it was adopted.

Experience
- We obtained a complete victory on behalf of Yale University in a first-of-its-kind jury trial in the District of Connecticut. The case involved allegations that Yale had breached its fiduciary duty to prudently monitor the plan's recordkeeping fees and investment lineup, as well as the share classes offered for those investments. After a five-week trial, the jury found no loss to the plan from Yale's failure to monitor recordkeeping fees, and no breach by Yale as to investment monitoring and share classes. As a result, the plaintiffs—who originally sought more than half a billion dollars, and asked in their closing for over $130 million from the jury—were awarded zero dollars in damages. We also achieved very favorable settlements in similar lawsuits against Cornell University, Columbia University, Long Island University and the University of Rochester, without even certifying a class in the latter two.
- We won a dismissal for Marmon Holdings Inc.—a Berkshire Hathaway-owned company—as well as its board of directors and retirement plan committee in a putative ERISA class action brought in the US District Court for the Northern District of Illinois. Similar to dozens of other cases in the past few years, the plaintiffs alleged that the Marmon defendants breached their fiduciary duties by charging plan participants excessive recordkeeping fees and offering imprudent investments. Following multiple rounds of briefing, including on the Seventh Circuit's recent plaintiff-friendly decision in Hughes v. Northwestern University, the court ruled that plaintiffs failed to state any claim.
- We obtained a complete dismissal with prejudice for Cook Group Incorporated in a putative class action ERISA lawsuit brought in the US District Court for the Southern District of Indiana. Similar to dozens of cases that have been brought in the past few years, many of which we have successfully defended, plaintiff alleged that Cook Group and members of its retirement benefits committee breached their fiduciary duties by charging retirement plan participants excessive recordkeeping and administrative fees. Following multiple amended complaints and rounds of briefing, including on the Seventh Circuit's recent plaintiff-friendly decision in Hughes v. Northwestern University, the team convinced the court that plaintiff had failed to state any claim.
- We scored a decisive win for Georgetown University when a federal district judge rejected the plaintiffs’ second attempt to amend their complaint to raise new allegations after dismissal of the prior class action lawsuit alleging that Georgetown mismanaged its retirement plan for faculty and staff. The court had dismissed the original complaint and rejected the plaintiffs’ first attempt to amend as untimely. However, on appeal, the DC Circuit reversed on procedural grounds and remanded. On remand, the plaintiffs again moved for leave to file an amended complaint and the team opposed that motion. This time, the court rejected the new motion to amend as futile in a 47-page opinion and described the case as a “lawsuit in search of a theory.”
- We obtained an across-the-board repudiation of unfounded claims for breach of fiduciary duty on behalf of WEC Energy Group, this time in the Eastern District of Wisconsin. Dismissing Plaintiffs’ claims that the company imprudently overpaid for recordkeeping costs and imprudently selected supposedly underperforming investments for its 401(k) Plan, the Court concluded that Plaintiffs’ case was “much ado about nothing of substance.” Moreover, picking up on one of our key themes, the court held that Plaintiffs could not 'present manipulated data that contradicts' key documents, putting the kibosh on an all-too-common ploy of the ERISA class action plaintiffs’ bar.
- We, after a hard-fought battle in an ERISA class action—and a refusal by a leading plaintiffs' firm to settle—achieved another across-the-board win at trial, this time in the Central District of California. The team put to bed claims that our client, Wood Group US Holdings Inc., imprudently managed its US 401(k) plan and, in doing so, breached fiduciary duties under ERISA.
- We obtained a favorable ruling for Nestlé U.S.A and its Board of Directors in a putative ERISA class action over the administration of its 401(k) retirement plan. Plaintiffs alleged that the Nestlé defendants breached their fiduciary duties under ERISA by allegedly causing the plan to pay excessive recordkeeping fees and excessive fees for managed account services.
- We secured a victory for Northrop Grumman Corporation when the Seventh Circuit Court of Appeals ruled that Northrop did not violate ERISA in reserving discretion for management to decide whether employees are entitled to severance benefits upon employment termination. Originally filed in 2013, and litigated before a series of three different Federal district court and magistrate judges, the case involved a variety of novel legal theories challenging employers’ authority under ERISA to design benefit plans that afford them discretion over benefits eligibility decisions.
- We obtained a complete dismissal in a putative class action against healthcare corporation, Centene Corporation. Plaintiffs alleged that Centene had mismanaged its $3 billion retirement plan and caused participants to pay excessive fees. Recent decisions on the plausibility of such claims have been mixed, but the team convinced the court to dismiss all of the claims with prejudice.
- We secured in important victory for an electric power holding company and its Benefits Committee in a nationwide ERISA class action challenging the administration of its 401(k) plan, with more than 39,000 participants and $8.6 billion in assets. The claims alleged breach of fiduciary duty by causing the plan to pay allegedly excessive recordkeeping and administrative fees and managed account services fees. After two years of hard-fought litigation, the plaintiffs voluntarily dismissed their case with prejudice, withdrawing all claims against our client and the company.
- We represented a global telecommunications company in a nationwide class action challenging the administration of its 401(k) plan with more than 240,000 participants and an excess of $34 billion in assets. The claims challenged various administrative and investment actions taken by our client in administering and operating the benefit plan. We were successful in convincing the district court to dismiss the plaintiff’s claims against our client and the individual fiduciary defendants.
- We convinced a California federal court to dismiss all of the plaintiff’s claims alleging that the Board of Directors of the Motion Picture Industry Pension Plans (“MPI”) breached their fiduciary duties by offering a retirement plan with a pooled-asset design and by investing a portion of the plan’s assets in hedge funds and other alternative investments. In granting MPI’s motion to dismiss, the court found that the plan’s pooled-asset design complied with ERISA and that investing in the alternative investments was consistent with the plan’s stated purpose of generating consistent returns in all market environments.
- We secured a major victory for Georgetown University by obtaining dismissal of a class action lawsuit alleging they had mismanaged its retirement plan for faculty and staff. Plaintiffs alleged that they were entitled to hundreds of millions of dollars in damages, but we convinced the court that the claims did not warrant discovery.
- We secured a major victory for Cornell University in a pending class-action lawsuit about the university’s retirement plan. A New York federal court deemed two of the plaintiffs’ expert witnesses to be unreliable and granted summary judgment to Cornell on claims accounting for more than 99.9% of the plaintiffs’ asserted damages. Plaintiffs have now appealed the dismissal of the other claims to the Second Circuit Court of Appeals.
- We represent a global oil and gas company and its affiliates in a highly publicized class action challenging the administration of its 401(k) plan with more than 33,000 participants and $10 billion in assets. The plaintiffs challenge many administrative actions in administering and operating the plan and the trust, including the plan’s recordkeeping fees, its investment structure, and particular investments in the plan’s investment lineup. We successfully convinced the district court to dismiss Plaintiffs’ fiduciary breach claim challenging the plan recordkeeper’s alleged use of participant data to sell non-plan products, which reflects the plaintiff bar’s most recent attempt to expand fiduciary liability under ERISA.
- We represent a national entertainment company and two related committees in litigation challenging the investment options offered to participants in its savings and retirement plan and alleging breach of fiduciary duty arising from the plan’s decision to offer company-affiliated investment options to participants.
- We represent a telecommunications company in a hybrid collection action and class action alleging FLSA and ERISA violations by misclassifying its customer service representatives as exempt rather than non-exempt employees. We obtained dismissal of all claims alleging violations of ERISA.
- We represent a global food and beverage company and its Board of Directors in a putative ERISA class action over the administration of its 401(k) retirement plan alleging breach of fiduciary duty and challenging the recordkeeping fees and fees for managed account services.
- We represent a global engineering and consulting business in a putative ERISA class action challenging the administration of its 401(k) plan with more than 18,000 participants and $2.4 billion in assets. The plaintiffs challenge the plan’s investment structure and particular investments in the plan’s investment lineup. We obtained dismissal of all of plaintiff’s breach of fiduciary claims.
- We represent multiple healthcare organizations and their Board of Directors in putative ERISA class actions over the administration of their 401(k) and 403(b) retirement plans, alleging breach of fiduciary duty and challenging excessive recordkeeping and administrative fees. The claims also challenge the plans’ inclusion of actively managed investment options and stable value funds, and the specific share classes offered to plan participants.
- We represent a telecommunications company in a putative class action alleging that the company violated its fiduciary duties under ERISA by failing to unilaterally take control of and sell the putative class members’ investments in the stock of their former employer.
- We represent the trustees of the employees’ union pension and severance fund in multiple actions alleging that defendants should have transferred the participants’ assets under their former 401(k) plan to their new union’s plan. We secured the dismissal of claims brought in Illinois federal court. We also successfully convinced the courts in California to dismiss the bulk of the plaintiffs’ claims on a motion to dismiss, substantially limiting the potential exposure.
- We represent a trade group in two cases challenging the appropriateness of stable value funds offered within 401(k) plans.
- We obtained a complete dismissal of an ERISA class action accusing George Washington University (GWU) of mismanaging its retirement plan. The district court and the DC Circuit found that the plaintiff had previously released all of her claims against GWU and that the release’s narrow exclusion for claims brought “under” the university’s employee benefits plans did not preserve the plaintiff’s statutory claims under ERISA. We convinced the DC circuit to affirm the complete dismissal of the class action.
- We obtained a favorable opinion from the Second Circuit in an ERISA class action alleging fiduciary breach and challenging the fees charged for certain investments in a 401(k) plan. The opinion serves as prominent precedent in other ERISA class actions within the Second Circuit and as persuasive authority in other courts nationwide.
- We represented a global life insurance company in a class action challenging the application and effect of a cash balance formula. Among ruling on the merits of the ERISA statutory claim, the court of appeals held that the plaintiffs’ claim that they received insufficient notice of the amendment was barred by the applicable statute of limitations.
- We defended a global security company in two separate class actions in the Central District of California challenging the administration and investments of its 401(k) plan with excess of $16 billion in assets. The claims challenge various administrative and investment actions taken by our client’s management in operating the benefit plan. Our lawyers achieved a favorable settlement in the first of these class action cases after a week of trial had been completed. In the second case, we achieved a favorable ruling on a motion for summary judgment, prompting an eve-of-trial settlement.
- We defended a global defense company, including its investment management corporation, in an ERISA putative class action in connection with defined contribution plans’ investment options and fees, in the Southern District of Illinois. This long-running case involved a challenge to one of the nation’s largest 401(k) plans. A group of plaintiffs filed suit against our client and a subsidiary, alleging that their 401(k) accounts were subject to unreasonable fees and imprudent investment fund offerings. Plaintiffs alleged class-wide damages exceeding $1 billion. In a succession of proceedings that included two trips to the court of appeals and a cert petition, we succeeded in narrowing the claims and the terms of class certification. On the eve of trial, the case settled on favorable terms for our clients.
- We represented a financial services company as trustee and investment manager in a massive ERISA class action filed by employees of an automotive manufacturer who suffered retirement savings plan losses as the manufacturer’s stock declined.
- We defended a class action that alleged breach of fiduciary duty in the role of investment manager. The plaintiff class was composed of employees of a global oil company participating in a 401(k) plan. As a result of the Enron collapse, one of the investments in one of the funds within the 401(k) plan became worthless. Plaintiffs claimed damages in excess of $20 million. The case settled on the first day of trial.
- We successfully defended the defendant fiduciary from a financial services company in the leading Sixth Circuit decision governing fiduciary procedures in selecting and retaining 401(k) investment options.
- We defended the plan fiduciaries of a renewable energy company in a Department of Labor investigation into whether the plan administrator complied with the plan amendment placing a cap on employee contributions to the plan sponsor’s stock.
- We have also appeared as amicus in ERISA class actions alleging excessive fees in 401(k) plan administration and investment management in:
- Thole v. U.S. Bank (Eighth Circuit)
- Retirement Plans Committee of IBM v. Jander (Second Circuit)
- Tibble v. Edison International (United States Supreme Court)
- Renfro v. Unisys Corp. (Third Circuit)

- Howell v. Motorola Inc. (Seventh Circuit)
- Beesley, et al. v. International Paper Company (Seventh Circuit)
- Ellis v. Fidelity Management Trust Co. (First Circuit)
- Barchock, et al. v. CVS Health Corp. (First Circuit)
- CNH Industrial N.V. v. Reese (retiree medical benefits)
- We secured a win for an aerospace and defense technology company in a nationwide class action over pension benefits.

- We secured a victory for a telecommunications company when the court dismissed a putative class action challenging the company’s defined benefit plan’s use of actuarial assumptions. This case is part of an emerging wave of actuarial equivalence litigation that is sweeping the nation.
- We successfully defended a class action challenging the exclusion of certain pay from pension calculations for 18,000 retirees; the plan administrator’s position was upheld by the court in a decision reversing an adverse district court ruling, which could have cost $125 million in claimed benefits.
- We won summary judgment for the defendants in a class action brought to challenge calculation of lump sum pension payments to certain former employees.

- We represent a global auto parts manufacturer in two separate severance benefit lawsuits brought by former executives, alleging that they were entitled to greater severance payments under the company’s severance plan because they were Section 16 officers with significant policymaking authority under the Securities Exchange Act of 1934. One of the executives has brought a benefits claim while the other has brought a claim under ERISA that the company interfered with his right to receive the higher severance benefit.
