Foxes, Henhouses, and Pension Plans: 
Supreme Court Concludes Pensioners 
Receiving Promised Benefits Can’t Sue for 
Retirement Plan Mismanagement   
June 30, 2020 
In early June 2020, the Supreme Court handed down its decision i
n Thole v. U.S. Bank concerning the 
ability  of pension plan participants to sue plan fiduciaries who engage in al eged  misconduct. In 
Thole, 
the Court’s majority held, in a 5-4 decision, that pensioners receiving the full amount of their retirement 
benefits lacked standing to sue plan fiduciaries for self-dealing and mismanagement of pension plan 
investments. This Legal Sidebar provides background on federal pension plan regulation under the 
Employee Retirement Income Security Act (ERISA) a
nd standing to sue in federal courts; discusses the 
Court’s decision in 
Thole; and concludes with selected legal considerations for Congress.   
Background 
ERISA’s Regulation  of Pension Benefits 
ERISA provides a comprehensive federal scheme for regulating private-sector employee benefit plans, 
and currentl
y governs approximately 710,000 retirement plans. The Act does not require employers to 
offer pension benefits, but those that do must comply with the Act’s requirements. In general, ERISA 
regulates
 two types of pension plans: defined benefit plans and defined contribution plans. The 
Thole case 
involves a
 defined benefit plan, which “consist[s] of a pool of assets, rather than individual dedicated 
accounts.” In a defined benefit plan, an employee is promised a specified future benefit (traditional y, an 
annuity beginning at retirement) based on factors such as the employee’s salary, age, and years of service. 
ERISA general y requires the employer to fund a defined benefit plan adequately, invest plan assets and 
bear the risk for such investments, and compensate for any shortfal s. Should a defined benefit plan be 
terminated with insufficient funds to pay retirement benefits, t
he Pension Benefit Guaranty Corporation 
(PBGC) pays certain guaranteed benefits to plan participants, subject t
o statutory limits.

By contrast, 
a defined contribution plan (e.g., a 401(k) plan) is a retirement plan in which the 
contributions, but not the benefits, are specified. These plans provide each participant with an individual 
account that accrues benefits based on employer and employee contributions, as wel  as any income, 
expenses, and investment gains or losses to the account. The employee bears the investment risk, and the 
account value at the time of retirement may fluctuate or decline over time. Defined contribution plan 
benefits are not PBGC-insured. 
Over the past few decades, there has general y been 
a steady decline in the number of defined benefit 
pension plans, while the number of defined contribution plans has continued to increase. According to 
2017 data from the Labor Department, there ar
e approximately 35 mil ion  participants in defined benefit 
plans, and over 102 mil ion  participants in defined contribution plans. 
A central goal in enacting ERISA was to “protect . . . the interests of participants and . . . beneficiaries” of 
employee benefit plans and assure that participants receive promised benefits from their employers. To 
this end, ERIS
A imposes certain obligations on plan fiduciaries—persons who are general y responsible 
for the management and operation of employee benefit plans. Fiduciaries mus
t adhere to standards of 
conduct, which include a duty of loyalty, prudence, and diversification of plan investments. ERIS
A also 
“provid[es] for appropriate remedies, sanctions, and ready access to the Federal courts.” Under the Act, 
private parties as wel  as government entities can bring various
 civil actions to enforce ERISA’s 
provisions. Among these enforcement provisions, ERISA authorizes the Secretary of Labor, a participant, 
a beneficiary, or another plan fiduciary to bring a civil action to redress a breach of fiduciary duty. ERISA 
makes a plan fiduciary personal y liable  for breaches against an ERISA plan, and a breaching fiduciary 
may have to return “any losses to the plan resulting from a breach” and restore to the plan any profits 
made from misusing plan assets. 
Standing  to Sue 
Before a court can decide issues under ERISA or any other federal statute, it must determine whether it 
has jurisdiction to examine the issues in the case. As part of this inquiry, plaintiffs must convince a court 
that they have
 standing unde
r Article III of the Constitution to bring the legal action.
 Standing 
requirements general y involve determining the proper party to seek relief from a federal court. These 
requirement
s compel a plaintiff to demonstrate, among other things, an injury that is “concrete and 
particularized.” As the Supreme Court ha
s explained, such injury must be “real” and “not abstract,” and 
“it must affect the plaintiff in a personal and individual  way.” While Congress has the power to give a 
plaintiff the right to sue under a federal statute (so-cal ed “statutory standing”), such a statutory right does 
not automatical y confer constitutional standing under Article III. The Supreme Court has declared that 
plaintiffs must demonstrate a cognizable injury under Article III even when there is a statutory violation. 
The Thole Decision 
I
n Thole, two retired participants in U.S. Bank’s defined benefit pension plan filed a class action lawsuit, 
claiming the company and others violated ERISA’s fiduciary duty and other requirements by improperly 
investing the plan’s entire portfolio in high-risk equities (including a large portion in mutual funds 
managed by the company’s subsidiary) and paying themselves excessive fees. The retirees further 
claimed that this investment strategy resulted in approximately $750 mil ion  in losses to the plan and 
caused the plan to be underfunded. The participants sought various remedies in federal court, including a 
restoration of the losses to the plan and removal of the al egedly  offending fiduciaries. However, as the 
litigation  proceeded, U.S. Bank made a large contribution to the plan that al owed the plan to meet 
ERISA’s minimum funding standards. This change to the plan’s funding status spelled doom for the 
participants’ case. Because the plan was no longer at risk of default, the district court dismissed the 
retirees’ case a
s moot. The U.S. Court of Appeals for the Eighth Circuit
 affirmed the district court’s 
  
Congressional Research Service

decision, but on the grounds that ERISA does not authorize plan participants to sue for a breach of 
fiduciary duty when the plan is adequately funded.  
In comparison to the Eighth Circuit, which held that the participants lacked 
statutory standing under 
ERISA, the Supreme Court in 
Thole affirmed the judgment of the Eighth Circuit because the plan 
participants did not have 
constitutional standing to bring a case against the plan fiduciaries. Justice 
Kavanaugh, writing for the Court’s majority
, concluded that the plan participants did not have 
constitutional standing “for a simple, commonsense reason: [t]hey have received al  of their vested 
pension benefits so far, and they are legal y  entitled to receive the same monthly payments for the rest of 
their lives.” As the Court explained, because the plan participants receive the same level of benefits 
regardless of the case’s outcome, they had no concrete injury to support their standing to sue. 
The plan participants in 
Thole asserted, among other arguments, that the
y had constitutional standing to 
sue because they have an interest in the plan’s assets as a whole, and that injuries to the plan constitute 
injuries to individual  participants. The Court rejected this argument
, observing that, because the 
participants’ benefits are fixed and independent of the plan’s value, the participants had no cognizable 
interest in the plan itself. The participants also argued that they had standing to sue because they were the 
only party that could meaningfully police the plan fiduciary’s conduct. The Court refused to accept this 
argument as supporting Article III standing
, explaining that defined benefit plan fiduciaries “face a 
regulatory phalanx,” including regulation and monitoring by the Labor Department and other co-
fiduciaries.  
Justice Sotomayor authored a dissent in 
Thole, joined by three other Justices. As the disse
nt put it: “Does 
the Constitution compel a pension plan to let a fox guard the henhouse? Of course not.” Disagreeing with 
the Court’s majority, the dissent indicated, among other things, that the plan participants could sue to 
protect their interests in their pension plan’s assets. In the dissent’
s view, “because petitioners have an 
interest in payments from their . . . [pension] fund, they have an interest in the integrity of the assets from 
which those payments come.” The dissent furthe
r maintained that the participants had standing to sue 
because a breach of fiduciary duty is an injury to the participants, regardless of financial loss. 
Legal Considerations 
The Court’s ruling in 
Thole appears to restrict the circumstances in which defined benefit plan 
participants can sue pension plan fiduciaries for making al egedly  poor investment decisions, particularly 
when the amount of the participants’ pension benefits is unaffected by those decisions. While 
constitutional standing requirements may prevent plan participants from bringing legal actions against 
plan fiduciaries under these circumstances, the 
Thole decision does not curtail the authority of the Labor 
Department or other plan fiduciaries to sue to enforce ERISA’s fiduciary responsibilities. Additional y,  it 
is possible that the 
Thole case may have limited application in fiduciary breach cases involving more 
prevalent 
defined contribution plans. As the Court recognized, defined contribution plans are structured 
differently—unlike defined benefit plans, the value of defined contribution plan accounts may fluctuate 
based on a fiduciary’s investment choices. Because of this key difference, plan participants in these cases 
may have an easier time demonstrating their standing to sue. 
Going forward, a 
“wrinkle” in the 
Thole case may be the subject of future litigation. In its majority 
opinion, the Court
 pointed to an argument of the plan participants
’ amici: that the participants would have 
constitutional standing to sue when “the mismanagement of the plan was so egregious that it substantial y 
increased the risk that the plan and the employer would fail and be unable to pay the participants’ future 
pension benefits.” The Cour
t contended that the plan participants in 
Thole did not al ege this theory of 
standing, and that a “bare al egation” of plan underfunding did not demonstrate this risk of default on 
pension obligations. Based on this language, the Court arguably seems to imply that there could be cases

in which defined benefit plan participants could sue plan fiduciaries despite receiving promised benefits, 
assuming the participants can show that their benefits were in substantial jeopardy.
