The first half of 2025 delivered a series of landmark decisions in Employee Retirement Income Security Act (ERISA) cases, creating new challenges and clarifications for employers, plan fiduciaries, and third-party administrators alike. These rulings, ranging from the U.S. Supreme Court to federal district courts, signal significant shifts in the landscape of benefit plan litigation, demanding heightened vigilance and proactive strategies. From impacting how plaintiffs can bring excessive fee claims to scrutinizing the role of ESG in 401(k) plans and clarifying fiduciary duties for health plan administrators, these decisions are poised to reshape how retirement and health benefits are managed across the nation. Understanding their nuances is crucial for mitigating risk and ensuring compliance in an ever-evolving legal environment.

1. Supreme Court Lowers Pleading Bar for ERISA Prohibited Transactions

Perhaps the most far-reaching decision of the midyear came from the U.S. Supreme Court, which unanimously revived a proposed class action alleging retirement plan mismanagement against an Ivy League institution. In this pivotal April 17 ruling, the nation's highest court rejected an employer-side attempt to raise the pleading standard for an ERISA prohibited transaction claim. This reversal of the Second Circuit's November 2023 decision effectively reopens a proposed class action that alleged the institution's relationships with high-cost recordkeepers led their retirement plans to engage in ERISA-prohibited transactions.

"This decision clearly shifts the landscape for ERISA fiduciaries, signaling an imperative for plan sponsors to review their internal processes with renewed vigor," says Robert D'Anniballe, Managing Partner of QPWB’s Ohio and West Virginia Hubs, and leader of the firm’s ERISA and Employee Benefits national practice group.  "We anticipate increased scrutiny on plan expenditures and service provider relationships, making proactive compliance and robust documentation more critical than ever. We'll be closely monitoring how these procedural suggestions play out in the lower courts." Nevertheless, this latest ruling undeniably lowers the initial hurdle for plaintiffs seeking to challenge plan service provider relationships, forcing plan sponsors to meticulously document their fiduciary processes.

2. ESG Investing Under Fire in 401(k) Plans

In a development with profound implications for the burgeoning field of sustainable investing, a Texas district court delivered a significant blow to the incorporation of Environmental, Social, and Governance (ESG) factors in 401(k) plans. U.S. District Judge Reed C. O'Connor, in a January 10 ruling, held a commercial airline liable for breaching its ERISA fiduciary duty of loyalty. The court found that the airline, through its own actions and those of its investment manager, improperly allowed its corporate interest in ESG to influence 401(k) plan management. Specifically, Judge O'Connor faulted the Texas-based airline for failing to adequately oversee its investment manager’s ESG emphasis, including its proxy voting activities.

This district-level ruling has sent a message to benefits attorneys. The case is particularly impactful given the current political climate, with the current administration signaling a retreat from previous ESG postures. These combined factors indicate that ESG-oriented investments in retirement plans are now under considerable scrutiny. This ruling indicates potential new risks for plan fiduciaries exploring or maintaining ESG-focused investment options.

Sydney Croft, Associate in QPWB’s Pittsburgh, Pennsylvania Hub, and member of the firm’s ERISA and Employee Benefits national practice group, reinforces the principle that ESG investments should be vetted by plan fiduciaries in the same manner as they do other investment vehicles.  “It is crucial that the plan fiduciaries document their deliberations and decisions in this arena.”

3. Third-Party Administrators Face Heightened Fiduciary Scrutiny in Health Plans

This year, employers and health plan administrators received a critical reminder of fiduciary responsibilities from a Sixth Circuit panel's decision to revive a Michigan yacht company's allegations against its third-party administrator (TPA). The panel on May 21 reversed the dismissal of the yacht company's suit against its TPA. It was alleged that the third-party administrator mishandled out-of-network claims by overpaying providers and then claiming savings from collecting those overpayments, thereby breaching its fiduciary duties.

The Sixth Circuit concluded that the lower court erred in determining that the boat company's allegations were outside ERISA's reach. By demonstrating that the TPA retained control over plan assets, the yacht company had plausibly alleged that fiduciary duties under ERISA were implicated. This ruling in Michigan serves as a strong signal for employers to make inquiries into their health plan administrators' reimbursement practices and ensure robust oversight to mitigate litigation risks.

“Many Administrative Services Agreements contain provisions that permit a plan’s third-party administrator to collect excess medical charges. Before this ruling, this encouraged third-party administrators to retroactively seek appropriate pricing for an employer’s plan and its participants/beneficiaries when the focus should have been seeking the appropriate pricing before the plan and/or its participants or beneficiaries incurred the charges. This ruling enforces that level of prudence on 3(21) third-party administrators,” states QPWB Associate Sydney Croft.

Key Takeaways

• Pleading Standard Shift: The Ivy League institution decision mandates that employers prepare for an increase in prohibited transaction claims, requiring robust processes for vendor selection and monitoring.
• ESG Caution: The Texas-Based Airline ruling is a definitive warning: ESG considerations in 401(k) plans are under intense scrutiny. 
• TPA Accountability: The yacht company clarifies that TPAs for health plans bear significant fiduciary responsibilities, especially regarding out-of-network claims. Plan sponsors and their fiduciaries should vet and oversee their TPAs more diligently.

Looking Ahead: Shaping the Future of Benefit Plan Management

These three decisions collectively herald a period of heightened accountability and evolving standards for ERISA fiduciaries. The Supreme Court's stance in the University case suggests a more plaintiff-friendly environment for challenging plan fees, compelling plan sponsors to re-evaluate their compliance frameworks and documentation practices. The airline company case introduces a critical new dimension to fiduciary duty, forcing a re-evaluation of ESG integration within retirement plans and potentially curbing enthusiasm for such strategies without clear, fiduciary-first justifications. Finally, the yacht company case extends direct fiduciary liability more clearly to TPAs, pushing employers to demand greater transparency and oversight in health plan administration, particularly regarding cost management.

In the future, we can anticipate more aggressive litigation in these areas. Plan sponsors and fiduciaries must proactively adapt by enhancing their due diligence, meticulously documenting their decision-making processes, and ensuring all actions prioritize plan participants' best interests and financial well-being above all else. Remaining informed and seeking expert legal counsel will be more vital than ever to navigate this dynamic legal landscape effectively.
