Capital Group ERISA Arbitration Fight Reaches the Supreme Court as Justices Call for a Response

The Supreme Court on Thursday, October 1, 2026 asked former Capital Group employee Cathy Pover to respond to the company's petition seeking review of a Ninth Circuit ruling that kept her 401(k) self-dealing class action out of arbitration. The Capital Group ERISA arbitration dispute is now framed as a remedies question, whether a single participant in a defined-contribution plan can recover money for everyone else's accounts, and the answer could decide whether employers can use plan arbitration clauses to shut down plan-wide fiduciary-breach suits.

The request is not a grant. But it moves the petition out of the pile of filings the Court denies without asking the other side to weigh in, and it lands on a question that sits underneath a remarkable run of appellate decisions: eight federal courts of appeals have now refused to let an ERISA plan's arbitration clause strip participants of plan-wide relief. Each of those decisions rests on the premise that ERISA § 502(a)(2) gives a participant the right to sue on behalf of the plan for losses across the plan. Capital Group's petition attacks that premise directly.

For lawyers who track mass arbitration, the stakes are concrete. If plan-wide relief survives, ERISA fiduciary claims stay in court as representative actions. If the Court limits a participant to the losses in her own account, the effective vindication objection weakens, individual arbitration becomes viable, and a plan with 11,000 participants starts to look like a mass filing waiting to happen.

What did the Supreme Court do in the Capital Group ERISA case?

The Court issued what practitioners call a call for response. Capital Group filed its petition for a writ of certiorari on August 19, 2026, asking the Justices to review Pover v. The Capital Group Companies, Inc., No. 24-5298 (9th Cir. July 30, 2026). On October 1 the Court asked Pover to file a response, a step reported by Bloomberg Law the same day and by Law360 on October 2.

A respondent in the Supreme Court is not required to file a brief in opposition, and many waive the right when a petition looks unlikely to be granted. When the Court, or a single Justice, wants to hear from the other side before deciding, it requests a response. Under Supreme Court Rule 15, a brief in opposition is generally due 30 days after the Court's request, and extensions are routinely granted. Once the response and any reply are in, the petition is distributed for one of the Justices' private conferences.

Put simply: the Capital Group ERISA arbitration petition has cleared the first filter, but the Court has not decided to hear it.

What is Pover v. Capital Group about?

Cathy Pover worked for The Capital Group Companies, the Los Angeles investment manager that sponsors the American Funds mutual fund family. She participated in the company's defined-contribution plan, The Capital Retirement Savings Plan, which Bloomberg Law reports holds about $5 billion.

Plaintiff's counsel Sanford Heisler Sharp McKnight filed the class complaint on November 14, 2023 in the US District Court for the Central District of California, No. 2:23-cv-9657, on behalf of Pover and as a representative of roughly 11,000 plan participants. The complaint targets Capital Group's decision to offer five of its own proprietary American Funds on the plan's investment menu. Pover alleges that the funds were expensive and underperformed, that the plan's fiduciaries kept them because they generated substantial transaction fees for Capital Group, and that the decision generated millions of dollars in fees for a Capital Group subsidiary. The claims are for breach of ERISA's fiduciary duties of prudence and loyalty.

The merits have not been reached. Everything that has happened so far concerns forum: whether Pover's claims belong in federal court or in individual arbitration.

The plan's arbitration clause and its fallback

The plan document contained two provisions that drove the outcome. First, it required arbitration of disputes and included a waiver of any claims brought on "a class, collective, or representative basis." Second, it contained a non-severability fallback: if the waiver "is found to be unenforceable by a court of competent jurisdiction, then any claim on a class, collective, or representative basis shall be filed and adjudicated in a court of competent jurisdiction, and not in arbitration."

That second sentence is a familiar drafting choice. Sponsors include it because they would rather defend a representative action in court, with appellate review, than face plan-wide liability in a single arbitration. The Severability Clause, in other words, was written to make the waiver an all-or-nothing bet.

Why did the Ninth Circuit refuse to send the Capital Group 401(k) case to arbitration?

On August 13, 2024 the district court denied Capital Group's Motion to Compel Arbitration and to dismiss, holding the waiver unenforceable under the Effective Vindication Doctrine and reading the fallback to require that the representative claims proceed in court. After oral argument in August 2025, a divided Ninth Circuit panel affirmed in a published opinion on July 30, 2026.

Judge Danielle J. Forrest wrote for the majority, joined by Judge Jacqueline H. Nguyen. The majority framed the case as a collision between ERISA, which entitles participants to sue for mismanagement of their plan, and the Federal Arbitration Act (FAA), which requires courts to enforce valid arbitration agreements according to their terms. The effective vindication doctrine is the narrow exception the Supreme Court has recognized for an arbitration agreement that operates as a prospective waiver of a party's right to pursue statutory remedies; American Express Co. v. Italian Colors Restaurant, 570 U.S. 228 (2013), confirmed that the exception exists while declining to apply it to the cost of proving an antitrust claim.

The majority held that Capital Group's waiver fell within the exception because it forbade Pover from asserting her right under ERISA to sue as a representative of the plan for plan-wide relief. Section 502(a)(2) authorizes a participant to bring an action for "appropriate relief" under § 409, which makes a breaching fiduciary personally liable to the plan for losses resulting from the breach. A clause that confines the participant to her own account, the majority reasoned, does not merely pick a forum; it removes a remedy the statute provides.

Having found the waiver unenforceable, the panel applied the plan's own fallback. Because the plan said that representative claims must then be adjudicated in court "and not in arbitration," Pover's fiduciary-breach claims stay in the Central District of California.

The VanDyke dissent

Judge Lawrence VanDyke dissented. In his view the majority erred in finding the clause unenforceable, because the bar on "representative" suits in the plan's class-action waiver does not refer to third-party suits brought on behalf of the plan. Read that way, the waiver would block Pover from representing other participants as a class but would not stop her from pursuing the plan's claim, and the effective vindication problem would disappear.

The dissent matters for the petition. A split panel, a published opinion, and a dissent that offers a narrower reading are the ingredients the Court looks for when it decides whether a question is genuinely contested.

What question is Capital Group asking the Supreme Court to decide?

Capital Group did not ask the Court to decide whether ERISA plans can mandate arbitration. Its petition asks whether "appropriate relief" for a defined-contribution plan participant under § 502(a)(2) includes monetary recovery to other participants' individual retirement accounts.

That framing is deliberate. The arbitration ruling depends on the premise that § 502(a)(2) relief is plan-wide. If the Court holds instead that a defined-contribution participant can recover only the losses in her own account, then a waiver that confines her to individual relief takes nothing away from her, and the effective vindication objection loses its foundation. According to Bloomberg Law's report, the petition also argues that the majority rule misreads ERISA's text and conflicts with principles of equitable relief and Article III standing.

The Supreme Court has addressed adjacent ground before. In Massachusetts Mutual Life Insurance Co. v. Russell, 473 U.S. 134 (1985), it described § 409 relief as running to the plan as a whole. In LaRue v. DeWolff, Boberg & Associates, 552 U.S. 248 (2008), it held that § 502(a)(2) authorizes recovery for fiduciary breaches that impair the value of plan assets in a participant's individual account. Neither decision squarely answered whether one defined-contribution participant can recover for everyone else's account, which is the gap the petition says the lower courts have split over.

Is there a circuit split on ERISA § 502(a)(2) relief?

Capital Group describes a 1-7 split. On its count, the Second, Third, Fifth, Sixth, Tenth, and Eleventh Circuits have held that a single defined-contribution participant can seek § 502(a)(2) relief for other participants' accounts, and the Ninth Circuit holds that § 502(a)(2) does not limit plaintiffs to the losses in their own accounts. The outlier is the Fourth Circuit, where, the petition says, plaintiffs can seek monetary recovery only to their own "individual retirement account[s]."

The most recent Fourth Circuit word on the subject is Trauernicht v. Genworth Financial Inc., No. 24-1880 (4th Cir. Mar. 10, 2026), which reversed certification of a mandatory Rule 23(b)(1) class after describing § 502(a)(2) claims in a defined-contribution plan as "individualized monetary claims." That decision was about Class Certification, not arbitration, but its view of § 502(a)(2) is the one Capital Group wants adopted nationally.

Respondents in this posture typically argue that a lopsided split is not a real conflict, or that the case is a poor vehicle because the decision below turned on an arbitration clause rather than the remedies question itself. Expect Pover's response to make both points, and to lean on the plan's fallback clause: even if Capital Group won on remedies, the representative claims were routed to court by the plan's own words.

How the remedies question reaches the Capital Group ERISA arbitration fight

The appellate record on ERISA plan arbitration is unusually one-sided. Nixon Peabody counted eight federal courts of appeals as of August 25, 2026 holding that plan sponsors cannot use an Arbitration Clause to thwart group claims and limit participants to individual actions. The Fifth Circuit, in Parrott v. International Bancshares Corp. on February 10, 2026, said it was joining the Second, Third, Sixth, Seventh, Ninth, Tenth, and Eleventh Circuits.

Court	Decision	Date	What it held about the plan clause
Seventh Circuit	Smith v. Board of Directors of Triad Manufacturing, Inc.	2021	Clause barring plan-wide remedies unenforceable under effective vindication
Tenth Circuit	Harrison v. Envision Management Holding, Inc., 59 F.4th 1090	2023	Same result for an ESOP plan clause
Third Circuit	Henry v. Wilmington Trust, 72 F.4th 499	2023	Provision barring plan-wide monetary or equitable relief unenforceable
Second Circuit	Cedeno v. Sasson, 100 F.4th 386	2024	Representative-capacity bar on §§ 502(a)(2) and 409(a) claims unenforceable
Sixth Circuit	Parker v. Tenneco, Inc.	2024	Individual arbitration provisions in 401(k) plans unenforceable
Ninth Circuit	Platt v. Sodexo, S.A.	Aug. 4, 2025	Split the analysis claim by claim
Second Circuit	Duke v. Luxottica U.S. Holdings Corp.	Feb. 5, 2026	Reaffirmed Cedeno on a representative-capacity bar
Fifth Circuit	Parrott v. International Bancshares Corp.	Feb. 10, 2026	Plan's consent can bind § 502(a)(2) claim, but representative waiver invalid; individual claims not compelled absent personal consent
Ninth Circuit	Pover v. The Capital Group Companies, Inc., No. 24-5298	July 30, 2026	"Class, collective, or representative" waiver invalid; fallback sends case to court
Fourth Circuit	Trauernicht v. Genworth Financial Inc., No. 24-1880	Mar. 10, 2026	Not an arbitration case; called DC-plan § 502(a)(2) claims "individualized monetary claims"

Every arbitration ruling in that table depends on reading § 502(a)(2) to protect a participant's right to pursue relief for the whole plan. The Supreme Court has never had to test that reading in the arbitration context because no circuit has disagreed on the arbitration question itself. Capital Group's petition is a way around that problem: instead of asking the Court to resolve a split that does not exist on arbitration, it asks the Court to resolve the remedies split that does exist, knowing the arbitration consensus rests on it.

Parrott also shows how much remains open even inside the consensus. The Fifth Circuit held that, for a § 502(a)(2) claim, the plan's consent to arbitrate is what counts, and that the plan validly consented when the sponsor used its amendment power. That reasoning would let sponsors amend plans to require arbitration of plan claims, so long as the arbitration preserves plan-wide relief. The court still refused to compel the plaintiff's individual claims because he never personally agreed to arbitrate.

Does a Supreme Court call for a response mean the Court will take the case?

No. A call for response means at least one Justice wants the respondent's views before the Court votes on the petition. It raises the odds of review compared with a petition that draws no interest, but many petitions are denied after a response is filed. A grant requires four votes at conference.

The likely sequence from here:

Step	Timing
Ninth Circuit decision in Pover	July 30, 2026
Capital Group files cert petition	August 19, 2026
Court requests Pover's response	October 1, 2026
Brief in opposition due (Rule 15, absent extension)	About 30 days after the request, around early November 2026
Capital Group reply, then distribution for conference	Typically several weeks after the opposition
Grant, denial, or a call for the Solicitor General's views	Winter 2026–2027 at the earliest

If the Court grants review by January 2027, the case could be argued and decided in the current Term, with a decision by the end of June 2027. A later grant would push argument into the October 2027 Term. The Court could also invite the Solicitor General to file a brief expressing the views of the United States, a common step in ERISA cases given the Department of Labor's enforcement role, which would add months.

In the meantime, nothing in the Ninth Circuit's mandate stops the case from moving forward in the district court unless Capital Group obtains a stay.

Can a 401(k) plan force participants into individual arbitration?

Under current appellate law, a 401(k) plan generally cannot use an arbitration clause to force participants to give up plan-wide relief for fiduciary breaches. Courts have struck clauses that require individual arbitration of § 502(a)(2) claims, that bar representative actions, or that cap relief at the claimant's own account. Nixon Peabody reports that carve-outs for injunctive relief, savings clauses promising whatever remedies ERISA allows, and general severability language have all been tested on appeal and failed.

What remains untested, according to the same analysis, is narrower: a delegation of arbitrability questions to the arbitrator through a Delegation Clause, and a clause that requires arbitration without the waiver language that every court has invalidated. Parrott suggests a third path, which is arbitration of plan claims on a plan-wide basis, consented to by the plan through amendment. None of those structures would deliver what sponsors really want from an individual arbitration requirement, which is to break a plan-wide claim into small individual ones.

A Supreme Court ruling for Capital Group would change that calculus. If § 502(a)(2) relief for a defined-contribution participant is limited to her own account, a Class Action Waiver plus an individual arbitration requirement would no longer strip any statutory remedy, and the effective vindication objection would fall away.

What it means for plan sponsors, ERISA plaintiffs' counsel, and mass arbitration firms

For plan sponsors and drafters. Plans that added arbitration language in recent years likely contain provisions every circuit to consider them has rejected. The petition does not change that today. Sponsors deciding whether to keep, remove, or redraft clauses should note that the most aggressive form of the clause, an individual-relief limit, is the one that would benefit most from a win for Capital Group and is the one most likely to be struck if the Court denies review. The non-severability fallback in Capital Group's plan worked as designed: it kept a plan-wide claim out of a single arbitration. Sponsors who omit such a fallback risk an arbitrator hearing a representative claim with plan-wide exposure and limited Vacatur review.

For ERISA plaintiffs' counsel. Representative § 502(a)(2) litigation, including excessive-fee, proprietary-fund, forfeiture, and tobacco-surcharge suits, relies on the plan-wide relief premise. A grant would invite stays of motions to compel arbitration and of class proceedings in pending cases while the Court decides. Expect defendants to cite the petition when seeking stays; the arbitration gate is already decisive in cases such as Hicks v. Waffle House, which a Georgia federal court paused on September 25 pending a ruling on the employer's motion to compel arbitration of an ERISA tobacco-surcharge class claim.

For mass arbitration firms. A defense win would open a door the defense bar may come to regret. Defined-contribution claims are classic negative-value claims on an individual basis: a participant's share of a fee overcharge is often a few hundred or a few thousand dollars. If individual arbitration of those claims becomes enforceable, claimants' firms can file thousands of individual demands under the American Arbitration Association (AAA) or JAMS rules that a plan document incorporates, triggering per-case fees for the employer and the dynamics that made Mass Arbitration a strategic threat in consumer and employment disputes. The roughly 11,000 participants in Capital Group's plan alone would exceed most provider mass filing thresholds many times over.

For funders and insurers. Fiduciary liability carriers price ERISA class exposure on the assumption that claims proceed as representative actions. A shift to individual arbitration would alter defense costs, settlement structures, and the value of Third-Party Litigation Funding portfolios built around ERISA class recoveries.

FAQ

What did the Supreme Court do in the Capital Group ERISA case?

On October 1, 2026, the Supreme Court asked Cathy Pover to file a response to Capital Group's petition for certiorari. It did not grant review; it asked to hear from her before deciding whether to take the case.

What is Pover v. Capital Group about?

Pover alleges that Capital Group's fiduciaries breached their duties of prudence and loyalty by keeping five proprietary American Funds in the company's roughly $5 billion 401(k) plan because the funds produced fees for Capital Group. The appeal concerns only whether the case belongs in court or individual arbitration.

Why did the Ninth Circuit refuse to send the Capital Group 401(k) case to arbitration?

The majority held that the plan's waiver of "class, collective, or representative" claims was unenforceable under the effective vindication doctrine because it barred Pover from seeking plan-wide relief under ERISA § 502(a)(2). The plan's fallback clause then required representative claims to be decided in court.

Is there a circuit split on ERISA § 502(a)(2) relief?

Capital Group says the split is 1-7: seven circuits, including the Ninth, allow a defined-contribution participant to seek relief for other participants' accounts, while the Fourth Circuit limits recovery to the plaintiff's own account. There is no comparable split on the arbitration question itself.

Does a Supreme Court call for a response mean the Court will take the case?

No. It signals that at least one Justice wants the respondent's views, which improves the petition's prospects, but the Court still needs four votes to grant and denies many petitions after a response is filed.

What happens next in the Capital Group Supreme Court petition?

Pover's brief in opposition is due about 30 days after the October 1 request unless extended, followed by Capital Group's reply and distribution for conference. A grant, a denial, or an invitation to the Solicitor General is unlikely before winter 2026–2027.
