A Quiet Docket, a Loud Signal for Benefits Leaders
The Supreme Court closed its October 2025 Term on June 30, 2026, and for once the biggest story for employee benefits is what the justices didn’t take up. After several years of consequential ERISA rulings, this term was unusually light on benefits cases. ERISA was the only major regulatory area the Court touched at all this cycle.
For CHROs and CFOs, that quiet is deceptive. The decided cases were narrow, but the case the Court agreed to hear for next term, combined with a fast-moving wave of litigation in the lower courts, means the exposure landscape is shifting under your feet even in a slow year. Here is what actually happened, and what belongs on your calendar.
A quick scheduling note. The Court runs on a fixed rhythm, opening the first Monday in October and running through late June. This term began October 6, 2025 and wrapped June 30, 2026. The next term, October Term 2026, begins October 5, 2026. That is when the case worth watching most closely will be argued.
The One Decided Case: M&K Employee Solutions
The term’s marquee ERISA decision was M&K Employee Solutions, LLC v. Trustees of the IAM National Pension Fund, decided unanimously on May 21, 2026, in an opinion by Justice Jackson.
The case concerned multiemployer pension plan withdrawal liability, the “exit tax” an employer owes when it stops contributing to an underfunded union pension plan. The narrow legal question: must the plan’s actuary lock in the actuarial assumptions, most importantly the interest and discount rate, as of the measurement date, or can those assumptions be set later? The Court held that assumptions do not have to be fixed on the measurement date. The measurement date fixes the facts about the plan, its assets, its participant data, but the actuary may select assumptions afterward, so long as they rest on information available as of that date.
Why It Matters, and to Whom
If your organization participates in a multiemployer plan, this decision removes a timing-based defense to a withdrawal liability assessment. The stakes are not theoretical. In the underlying dispute, a single change in the discount rate swung the fund’s unfunded liability from roughly $500 million to $3 billion. Employers can still challenge an assumption as unreasonable on the merits, but they can no longer argue it is invalid simply because it was adopted after the measurement date.
For CFOs with any multiemployer exposure, the practical takeaway is straightforward: keep current withdrawal-liability estimates in hand and treat assumption volatility as a live balance-sheet risk, not a historical footnote.
For the majority of employers, those sponsoring 401(k) or other single-employer defined contribution plans, M&K is informative but not directly actionable. Which is exactly why the next case deserves your attention.
The Case to Watch: Anderson v. Intel
In January 2026, the Court granted review in Anderson v. Intel Corp. Investment Policy Committee. This is the decision benefits leaders should be tracking closely. It has not yet been argued. It sits on the October 2026 calendar, with a ruling expected sometime in 2027.
The question is deceptively technical but enormously consequential: when a 401(k) participant sues plan fiduciaries for imprudently selecting or retaining an underperforming investment, must the complaint identify a “meaningful benchmark,” an appropriate comparator investment, to survive a motion to dismiss?
That pleading standard is the gate through which nearly every fiduciary-breach class action must pass. Set it high, and many suits end early, before discovery costs accumulate. Set it low, and far more cases proceed into expensive, prolonged litigation. However the Court rules, it will reset the cost-benefit calculus of fiduciary litigation for every plan sponsor in the country.
The action item here is concrete: put Anderson v. Intel on your 2027 watch list now, and revisit your investment-monitoring documentation in anticipation. Whatever standard the Court ultimately adopts, employers with a thin or informal fiduciary process will be the most exposed.
The Real Action Is Below the Supreme Court
If you read only the SCOTUS headlines, you would miss the trend most relevant to your benefits program today. Two lines of litigation are accelerating in the lower courts, and both are worth understanding now, well before either reaches the Supreme Court, if either ever does.
Voluntary and Ancillary Benefits Litigation
Building on the Court’s 2025 decision in Cunningham v. Cornell, last term’s ruling that lowered the bar for pleading an ERISA prohibited-transaction claim, plaintiffs’ firms have begun filing class actions over voluntary benefit programs such as accident, critical illness, and hospital indemnity coverage.
The theory: that employers failed to ensure premiums were reasonable, and that the brokers and consultants who placed those products acted as plan fiduciaries and engaged in self-dealing through undisclosed commissions. Notably, these suits name not just employers but their advisors directly.
The first line of defense is the Department of Labor’s voluntary-plan safe harbor. If your voluntary offerings do not satisfy all four of its requirements, ERISA fiduciary duties may attach to programs you never treated as fiduciary plans. That means the governance, documentation, and disclosure standards you apply to your 401(k) may now be relevant to your accident and critical illness offerings as well.
Forfeiture Litigation
A growing set of cases is challenging whether plan sponsors may use forfeited employer contributions, the unvested employer match dollars left behind when an employee departs before vesting, to offset future company contributions, rather than using those dollars to defray plan administrative expenses.
The Supreme Court has not taken these cases up, but the circuits are actively sorting through conflicting outcomes, and the resolution will shape a routine plan-design choice that most sponsors make without a second thought. If your plan document allows forfeitures to offset future employer contributions, a common and previously uncontroversial provision, it is worth understanding where the circuit split currently stands and how exposed your specific plan language is.
On the Health Side: A Notable Non-Decision
In January 2026, the Court declined to wade in. It denied review in Guardian Flight v. Health Care Service Corp., leaving intact a lower court ruling that there is no private right of action to enforce arbitration awards under the No Surprises Act’s dispute-resolution process. It’s a quiet development, but a meaningful data point for any employer managing surprise-billing and network-adequacy issues. The enforcement mechanism for No Surprises Act arbitration outcomes remains narrower than some plan sponsors may have assumed.
What to Do Before October
A light term is a planning window, not a reprieve. Three concrete moves worth making before the Court reconvenes:
- Document your fiduciary process for both retirement and welfare plans. Courts increasingly judge prudence by process, not by hindsight outcomes. Regular committee meetings, engagement of outside expertise, and documented ongoing monitoring are what hold up under scrutiny, for your 401(k) and increasingly for your health and ancillary plans as well.
- Inventory your voluntary and ancillary programs against the DOL safe harbor. Scrutinize the commissions your brokers and consultants earn on accident, critical illness, hospital indemnity, and similar products. Confirm all four safe harbor requirements are met, and ask directly whether your advisors are being compensated in a way that could be characterized as self-dealing.
- Calendar Anderson v. Intel for the 2026 to 2027 term. Pressure-test your investment-monitoring file against a “meaningful benchmark” standard now, while you have time to strengthen it before a ruling potentially resets the litigation landscape.
The Justices Return October 5. The Quiet Won’t Last.
This term’s light docket should not be mistaken for reduced risk. The lower courts are actively developing theories around voluntary benefits, forfeitures, and fiduciary process that will shape benefits litigation for years regardless of whether the Supreme Court ever weighs in directly. And the one case already on next term’s calendar, Anderson v. Intel, has the potential to reset how every fiduciary-breach claim in the country gets pleaded and litigated.
Benefits compliance is not a once-a-year exercise triggered by a Supreme Court ruling. It is an ongoing discipline of documentation, benchmarking, and process, and the employers best positioned heading into next term are the ones treating it that way now.
Mployer’s benefits rating evaluates plan design and employer investment across Medical, Ancillary, Leave, and Retirement, giving CHROs and CFOs a documented, benchmarked view of how their plans compare to a custom cohort. That is precisely the kind of process discipline courts are increasingly looking for.
This is also where Mployer Insights+ does double duty. Running an Insights+ review produces the kind of independent, third-party documentation that speaks directly to ERISA’s prudent expert standard under Section 404(a)(1)(B). The report benchmarks your plan against a custom cohort matched by size, region, and industry, which gives you a data-driven basis for evaluating whether your costs and plan design fall within a reasonable market range under the cost reasonableness standard in Section 404(a)(1)(A).
It also addresses the duty to monitor under Section 404(a)(1), which is an ongoing obligation, not a one-time exercise at plan inception. An annual Insights+ re-rating establishes exactly the kind of recurring, documented review cadence that obligation calls for, with a written output each cycle that shows the analysis was conducted. Because the report is produced by an independent third party with no carrier or broker relationship to the plan being evaluated, it also speaks to the independence of assessment that the prudent expert standard implies.
None of this is a substitute for legal advice, and plan sponsors should work with qualified ERISA counsel to confirm all applicable obligations are identified and satisfied. But for CHROs and CFOs looking to strengthen their fiduciary process ahead of a term where the lower courts are actively raising the bar on documentation, an annual Insights+ review is a concrete, repeatable way to build that record.
