4th Circuit Refusal to Rehear Trauernicht v. Genworth Impacts Class Certification

The U.S. 4th Circuit Court of Appeals has declined to rehear the case of Trauernicht v. Genworth Financial, Inc., affirming a lower court’s decision to deny class certification in a 401(k) fiduciary lawsuit. According to reporting from Planadviser on June 9, 2026, this ruling limits the ability of plan participants to consolidate claims into a class action when alleging that a plan sponsor failed to properly monitor investment options.

The decision serves as a significant legal hurdle for plaintiffs seeking to hold employers accountable for high fees or underperforming funds within employee retirement plans. By standing by the denial of class certification, the court has signaled that the specific financial harms suffered by individual participants may be too varied to justify a single, collective lawsuit.

Why did the court deny class certification in Trauernicht v. Genworth?

The core of the dispute centered on whether the plaintiffs met the requirements for class certification under Federal Rule of Civil Procedure 23. In ERISA (Employee Retirement Income Security Act) cases, plaintiffs must demonstrate “commonality,” meaning there are questions of law or fact common to the entire class.

In this case, the plaintiffs alleged that Genworth breached its fiduciary duties by failing to monitor the 401(k) plan’s investment options and neglecting to replace funds that were overpriced or performed poorly. However, the court found that the alleged damages were too individualized.

Because different participants chose different investment mixes and entered the plan at different times, the court determined that the impact of the alleged fiduciary breach varied from person to person. This lack of uniformity meant that a single trial could not efficiently resolve the claims for all participants.

How does this ruling affect future 401(k) litigation?

This outcome creates a stricter pathway for participants trying to sue plan sponsors for fiduciary breaches. Many 401(k) lawsuits rely on the threat of class certification to force settlements, as the potential liability for a company increases exponentially when thousands of employees are included in a single suit.

The 4th Circuit’s refusal to rehear the case reinforces a legal distinction between a “uniform policy” and “individualized harm.” If a plan sponsor implements a specific, written policy that affects everyone identically, class certification is more likely. But when the claim is about a general failure to monitor a menu of options—where users have a choice in what they buy—courts are increasingly likely to view the resulting losses as individual rather than collective.

This ruling contrasts with broader trends in ERISA litigation where plaintiffs have successfully argued that the overarching failure to oversee a plan constitutes a common injury. By focusing on the variance in individual investment choices, the 4th Circuit has provided a defense strategy that other corporate plan sponsors can use to dismantle class actions.

What are the implications for plan sponsors and fiduciaries?

For companies like Genworth, the ruling is a victory that reduces legal exposure. It prevents the case from proceeding as a massive collective action, effectively forcing plaintiffs to either pursue their claims individually—which is often cost-prohibitive—or drop the suit entirely.

Plan sponsors now have a stronger precedent to argue that 401(k) lawsuits lack the necessary commonality for class status, provided the plan offers a variety of investment choices. This shifts the burden back to the employees to prove exactly how the fiduciary’s inaction caused a specific, quantifiable loss to their individual account.

• Reduced Settlement Pressure: Companies may be less inclined to settle early if they believe they can successfully block class certification.
• Focus on Individualized Damages: Defendants can argue that “commonality” is absent if participants had different investment allocations.
• Documentation Importance: The ruling highlights the need for sponsors to document their monitoring processes to prove they met their fiduciary duties, regardless of whether a class is certified.

The 4th Circuit’s decision ensures that the previous denial of class certification remains in place, leaving the plaintiffs without a viable path to proceed as a group in this specific litigation.
