OPINION

_________________

SUTTON, Chief Judge. Before us are two questions: Did the Chairman of the Federal 

Energy Regulatory Commission exceed his authority in moving for a remand of a ratemaking 

challenge without the support of any other members of the Commission? If not, did the 

Commission’s underlying ratemaking decisions sink to the level of arbitrary and capricious 

agency action? As to the first question, the Commissioner exceeded his administrative authority. 

We accordingly remand the matter to the agency in the first instance to determine what, if 

anything, can or should be done about this ultra vires action. Once the agency has had the 

opportunity to resolve that point, any interested party may renew the petition for review of the 

second question.

I.

Americans have come to expect their electricity and other forms of power to be available 

at the flick of a switch. But technology has not yet provided a cost-efficient way to store 

electricity. Utilities as a result must have the capacity to handle peak demand when consumers 

need it. Fed. Energy Regul. Comm’n, Staff Report, Energy Primer: A Handbook for Energy 

Market Basics 36–37, 46, 52 (Apr. 2020). Rather than make an expensive upfront investment in 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 3

generator capacity that would sit unused most of the time, utilities typically agree to buy and sell 

excess reserves to their neighbors as supply and demand require. Id. at 36–37. A utility 

normally purchases power from its neighbors when the price falls under its own cost of 

generating an additional unit of electricity, and it sells power when it can obtain a price above its 

own costs. Id. at 37. 

The market for electricity works only as well as power flows between generators and 

purchasers. Since the late 1990s, the government has required the utilities that own power plants 

to permit open access to their transmission lines. Id. at 39. When a power plant generates 

electricity, it flows across the entire transmission grid, mixing with power from other plants on 

its way to the purchaser. Id. at 54. Overseeing this transmission system for much of the country 

are “independent system operators” and “regional transmission organizations.” Id. at 39, 61. 

These entities forecast the wholesale demand for electricity and determine which generators and 

load-serving entities on their grid are in the best position to supply it. Id. at 63–64. They also 

maintain generation reserves by purchasing capacity not currently scheduled for operation and 

arranging for it to enter operation if power production unexpectedly falls. Id.

The oldest of these organizations and the largest measured by all-time peak load is PJM 

Interconnection, L.L.C. Id. at 62. It started in 1927 as a reserves-pooling agreement between 

three utilities and expanded in 1956 to become the Pennsylvania-New Jersey-Maryland 

Interconnection. Id. at 38, 85. Hence PJM’s current name. Today, the utility operates part or all 

of the transmission lines in 13 states in the mid-Atlantic and Midwest as well as the District of 

Columbia. Id. at 85. Governing PJM are a Board and a “Members Committee” representing five 

classes of stakeholders: power generators, transmission owners, electric distributors, power 

marketers, and large consumers. Id. at 86. Each day, PJM calculates the price of power at each 

location on the grid in advance and then adjusts the prices in real time. Id. at 87–88. 

PJM also obtains reserves to maintain the reliability of the transmission system. PJM 

maintains “Step 1” reserves sufficient to replace its largest online generator within 15 minutes 

and “Step 2” reserves to address other supply shortfalls or fluctuations. Id. at 88; JA0981–82, 

¶¶4–5. PJM acquires these reserves through auctions at which it offers to pay a price up to a 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 4

“reserve penalty factor” approved by the Commission. JA0983–84, ¶7; see Energy Primer, 

supra, at 88–89. As its name suggests, the reserve penalty factor functions as a price cap and 

represents the maximum price the agency is willing to allow the market to set for a quantity of 

reserves. Put another (slightly more accessible) way, it’s the highest cost that PJM will incur to 

redispatch its system to procure an additional megawatt of reserves. In 2012, the Commission 

approved a price cap for PJM’s Step 1 reserves of $850 per megawatt hour, and in subsequent 

years the next 190 megawatts of Step 2 faced a cap of $300 per megawatt hour. Beyond that 

point, PJM usually pays nothing for additional reserves. 

Over time, price caps create regulatory friction for businesses caught between fixed 

prices and ongoing market developments. See generally Samuel Evan Milner, Robbing Peter to 

Pay Paul: Power, Profits, and Productivity in Modern America 26–36, 178–81, 197–203 (2021) 

(providing examples of price controls that collapsed in the face of economic contingencies and 

dynamic markets). When PJM adopted its price caps for reserves, the maximum price at which 

energy suppliers could offer power to the market was $1,000 per megawatt hour. But in 2016, 

regulators raised the cap to $2,000 per megawatt hour. That change made it more difficult for 

PJM to obtain adequate reserves (by increasing the opportunity cost to forego market sales). 

This pricing schedule also did not place any value on additional reserves after the first 190 

megawatts on top of Step 1, a threshold that PJM believed had become obsolete in the face of 

changing power market conditions. Between 2015 and 2017, for instance, PJM calculated that 

fluctuations in wind power alone would consume over 80% of that reserve. In practice, PJM 

continued to obtain most of its necessary reserves and often paid an auction price of $0 per 

megawatt hour for reserves because power plants already operating could supply idle capacity at 

no cost. But PJM believed that it had achieved this result only by “biasing” generator scheduling 

and undertaking out-of-market support, workarounds that it saw as evidence that this pricing 

system was faltering and would eventually lead to shortages. JA0039–40, JA0683. 

Because PJM operates in the interstate market for transmitting and selling electricity, it 

could not modify its reserve price caps without approval from the Commission. See 16 U.S.C. 

§ 824. Regional transmission organizations ordinarily seek approval for new rates under 

16 U.S.C. § 824d, which requires a showing that the proposed rates are just and reasonable. But 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 5

PJM’s Operating Agreement allowed it to use that authority only if a weighted majority of its 

Members Committee approved it, and the Board failed to obtain the necessary stakeholder 

support. 

In March 2019, the PJM Board instead filed this request under 16 U.S.C. § 824e(a), 

which required PJM to prove both that its existing rates were unjust and unreasonable and that its 

proposed replacements would cure the defects. PJM requested two major changes from the 

Commission. It asked the Commission to raise the reserve price cap for Step 1 to $2000 per 

megawatt hour, reflecting the costs that it believed it would have to pay to obtain reserves. And 

it asked the Commission to replace the flat $300 per megawatt hour cap after Step 1 with a 

downward sloping price schedule that would more accurately account for the value of additional 

reserves. 

In May 2020, the Commission agreed with PJM that the existing price cap for reserves 

and stepwise demand curve were unjust and unreasonable. It found that PJM’s reserve market 

“systematically fail[ed] to acquire within-market” reserves needed to operate its system reliably 

for three reasons. JA0687. First, PJM operators frequently distort demand upward in market 

forecast software. This persistent bias, the Commission reasoned, likely shows that the need for 

reserves “far exceed[s]” the mandatory requirements, suggesting a flaw in the existing design. 

JA0688. Second, PJM’s minimum requirements are significantly lower as a percentage of peak 

load compared to other regional transmission organizations, but PJM faces higher operational 

uncertainties. Third, operators often acquire additional reserves at costs above the price caps for 

reserves through out-of-market uplift, meaning the existing caps do not reflect the true price of 

reserves. This evidence, the Commission explained, demonstrates a reserve market design that 

fails to acquire necessary reserves within the market and fails to “send appropriate price signals 

for efficient resource investment.” JA0687. The new price cap and demand curve were set to go 

into effect on May 1, 2022. Commissioner Richard Glick dissented, arguing that this evidence 

did not indicate a flawed market structure and that PJM “failed to satisfy its burden of proof.” 

JA0801. 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 6

Within a month, several interested entities requested a rehearing of the Commission’s 

decision. In November 2020, the Commission denied that request but issued a new order, 

confirming its initial decision. Several parties sought review of the orders in the U.S. Court of 

Appeals for the District of Columbia Circuit. In the meantime, the agency’s composition shifted. 

Commissioner Glick became Chairman in January 2021, and two new Commissioners replaced 

outgoing members: Commissioner Allison Clements joined in December 2020, and 

Commissioner Mark C. Christie joined in January 2021.

On August 13, 2021, the Commission sought a voluntary remand from the D.C. Circuit to 

“reconsider[]” its prior decisions. JA0885. The D.C. Circuit granted the unopposed motion ten 

days later and remanded the consolidated cases to the Commission. Unknown to PJM or, we 

presume, the court at the time, Chairman Glick had directed the Solicitor’s Office to seek the 

remand without notifying the other Commissioners and without holding a vote to consider the 

action. 

On remand, the Commission pivoted. It now found PJM’s evidence insufficient to show 

that the price caps for reserves and stepwise demand curve were unjust and unreasonable. While 

acknowledging operator distortions, out-of-market uplift, and PJM’s operational uncertainties, 

the agency found this evidence insufficient to show a problem with the reserve market. 

Operators, for example, distort demand upwards but also downwards (and sometimes not at all), 

suggesting that any bias may not correlate with reserve shortages. Out-of-market uplift does 

occur, the Commission likewise acknowledged, but it can stem from benign market forces 

unrelated to a shortage of reserves, such as settlements for mismatched prices. The Commission 

in the end decided that PJM had not provided evidence of a genuine, non-hypothetical risk of 

shortages. The Commission reimposed the prior price cap of $850 per megawatt hour for Step 1 

reserves and the stepwise, vertical demand curve for reserves beyond Step 1. James Danly, the 

remaining Commissioner (as the fifth seat was not filled), filed a separate dissent in which he 

disclosed that the Chairman had directed the Commission’s Solicitor to seek remand without first 

informing the other Commissioners. 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 7

PJM and others sought rehearing before the Commission, citing this newly disclosed 

procedural irregularity and challenging the substance of the agency’s shift in views. The 

Commission rejected the request but issued a modified order, reaching the same result, providing 

additional explanations, and (among other things) reasoning that Chairman Glick had the 

unilateral authority to make the remand motion. This petition for review followed. 16 U.S.C. 

§ 825l(b).

II.

Petitioners Electric Power Supply Association and PJM Power Providers Group 

(collectively, PJM) argue that the Chairman exceeded his legal authority when he requested a 

remand in the name of the Commission on his own. We agree. 

Look first at the statute to see why. The Commission consists of five Commissioners 

appointed by the President with the advice and consent of the Senate, one of whom the President 

designates as Chairman. 42 U.S.C. § 7171(b). The Commission may “transact[]” “business” 

only in the presence of at least three Commissioners. Id. § 7171(e). The majority vote of that 

quorum carries the day on all agency “[a]ctions.” Id.

This language establishes the default expectation that a quorum majority must decide the 

Commission’s policy and dealings with the outside world. “Business” encompasses the agency’s 

“normal, logical or inevitable” activity. Business, Webster’s Third New International Dictionary 

of the English Language 302 (1993). In a formal sense, the Commission’s business refers to 

matters that it deliberates over “for its consideration and action.” Business, Black’s Law 

Dictionary (11th ed. 2019). And an action refers to the agency’s “act or decision” or its “deed” 

or “thing done.” Action, Webster’s Third, supra, at 26. 

Other statutory language reinforces the idea that Congress requires a quorum majority to 

approve agency actions of this sort. Congress has charged the Commission with the power “to 

perform any and all acts” necessary to “carry out” its duties. 16 U.S.C. § 825h. It may “exercise 

any power” available to its predecessor agency that “the Commission determines” necessary to a 

“function” within its “jurisdiction.” 42 U.S.C. § 7172(2)(A) (incorporating 16 U.S.C. §§ 825e–

825h). The Commission has responsibility for the “establishment, review, and enforcement of 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 8

rates and charges” for electricity transmission and sales. Id. § 7172(a)(1)(B). And it may 

receive and evaluate complaints from utilities such as PJM that rates are not just or reasonable. 

See 16 U.S.C. § 825e. 

Each step of consequence in the life of a pricing order qualifies as an action of the agency 

that a quorum majority must approve. When the agency issues “orders,” that clearly qualifies as 

“actions of the Commission.” 18 C.F.R. § 375.102(b). The Commission thus may issue such an 

order only if a quorum majority approves it. See Advanced Energy United, Inc. v. FERC, 

82 F.4th 1095, 1101 (D.C. Cir. 2023). No surprise, if four members split evenly, no action 

results from the deadlocked quorum. Pub. Citizen, Inc. v. FERC, 839 F.3d 1165, 1170 (D.C. Cir. 

2016).

The same requirements apply when the agency modifies an existing order. “[T]he 

Commission” holds the power as a collective to “modify or set aside, in whole or part,” an order 

while it retains the record. 16 U.S.C. § 825l(a); cf. Allegheny Def. Project v. FERC, 964 F.3d 1, 

5 (D.C. Cir. 2020). Once the Commission has filed the record with the court of appeals, it no 

longer has the authority to take such an action. 16 U.S.C. § 825l(a). At that point, the agency 

may initiate a proceeding to issue a new order, id. § 824e(a), or it may request that the court 

remand the record to the Commission so that it may “reconsider, re-review, or modify the 

original agency decision.” Sierra Club v. EPA, 60 F.4th 1008, 1021 (6th Cir. 2023) (quoting 

Limnia, Inc. v. U.S. Dep’t of Energy, 857 F.3d 379, 387 (D.C. Cir. 2017) (Kavanaugh, J.)). 

Either way, the agency may act only when a quorum majority supports the decision. See 

Belmont Mun. Light Dep’t v. FERC, 38 F.4th 173, 182 (D.C. Cir. 2022) (noting that the 

Commission did not request voluntary remand in a case until it “regained a quorum”). 

Context reinforces this conclusion. When Congress has provided specific examples 

along with general phrases, we ordinarily assume that the specific sheds light on the general. See 

Dubin v. United States, 599 U.S. 110, 124–27 (2023). Congress has provided five examples of 

the Commission’s operation that fall within the Chairman’s responsibilities. Four of those 

pertain to personnel matters: appointing and employing hearing examiners; selecting and 

compensating personnel the Chairman deems necessary; supervising the Commission’s 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 9

personnel except for Commissioners’ personal staff; and employing experts and consultants. 

42 U.S.C. § 7171(c). The Chairman in particular may appoint an “executive director,” id., a 

position with the delegated authority to waive agency fees and charges, 18 C.F.R. § 375.312, and 

who otherwise carries out or administers the agency’s policies, cf. 5 U.S.C. § 8474(b)–(c); 

10 U.S.C. § 2903(b)–(d); 15 U.S.C. § 4805(a)–(b). The fifth responsibility requires the 

Chairman to distribute business within the Commission and its staff. 42 U.S.C. § 7171(c). None 

of these personnel or ministerial tasks describes or for that matter even hints at a unilateral 

authority to undo a Commission order by moving a court to remand the order to the agency. 

A separate statutory authorization for litigation authority cuts in the same direction. The 

Chairman may “designate[]” attorneys to represent the agency in civil litigation outside of the 

Supreme Court. Id. § 7171(i). This provision provides the Commission with increased 

independence from the President by permitting it to represent itself in court. See Consumer 

Energy Council of Am. v. FERC, 673 F.2d 425, 472 & n.194 (D.C. Cir. 1982); cf. 28 U.S.C. 

§ 518(a). That independence would vanish if the Chairman, whom the President designates from 

among the Commissioners, also could control the Commission’s litigation decisions by himself. 

See 42 U.S.C. § 7171(b). The statutes simply do not convey a better-to-ask-for-forgiveness-than 

permission approach to the Chairman’s authority over substantive matters.

These requirements make particular sense for multimember commissions. Quorum rules 

ensure that the actions of a collective body represent its whole, not its individual members. See 

New Process Steel, L.P. v. Nat’l Lab. Rels. Bd., 560 U.S. 674, 683–84 (2010); Fed. Trade 

Comm’n v. Flotill Prods., Inc., 389 U.S. 179, 183–84 (1967). So too for the requirement that the 

quorum must reach a majority viewpoint. See New Process, 560 U.S. at 684. Each of the five 

Commissioners may work independently of the others and hire and supervise their own personal 

staff, but none has the power to countermand an action of the agency. See 42 U.S.C. § 7171(b)–

(c). Only authentic actions of the Commission itself count. See id. § 7171(g) (assigning the 

“powers authorized by the law” to “the Commission”); 18 C.F.R. § 375.102(b) (requiring 

authentication of all Commission orders and other actions). Just as we colloquially ascribe the 

issuance of a rule or order to an agency and not its commissioners, we also typically ascribe a 

voluntary remand to that body “so that it could reconsider its decision.” E.g., Citizens Against 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 10

Pellissippi Parkway Extension, Inc. v. Mineta, 375 F.3d 412, 414 (6th Cir. 2004). Confirming 

the point, the agency concedes that the Chairman could not have sought a remand on his own—

even after a majority of Commissioners opposed it. Cf. Respondent’s Br. 40.

The Chairman’s request to the D.C. Circuit in this case bears out these expectations. The 

notice stated that the agency “request[ed]” that the D.C. Circuit grant a voluntary remand and 

informed the parties that the “Commission” made this request. JA0884–85. Nowhere in that 

document did it indicate that a quorum majority had not approved the decision, removing any 

legal force it otherwise would have carried. See Pub. Citizen, Inc., 839 F.3d at 1171. The D.C. 

Circuit in turn evaluated and granted the motion as if it had been the Commission’s own. All 

perspectives considered, the Chairman exceeded his authority by moving for a remand on his 

own. 

The Commission opposes this conclusion on several grounds. It starts with a procedural 

objection. How, it says, can PJM now challenge the Chairman’s authority to unilaterally file a 

motion for voluntary remand when it raised this issue for the first time many months after the 

motion was filed? Courts ordinarily require litigants to raise objections to the agency or the 

court at the first relevant opportunity. See McCarthy v. Madigan, 503 U.S. 140, 144–45 (1992) 

(administrative exhaustion); Bannister v. Knox Cnty. Bd. of Educ., 49 F.4th 1000, 1011 (6th Cir. 

2022) (forfeiture). But when a party fails to raise an argument of which it was not reasonably 

aware, its failure to make a timely assertion of that right does not prevent it from doing so at the 

first reasonable opportunity. See United States v. Olano, 507 U.S. 725, 733–34 (1993); 

Bannister, 49 F.4th at 1012 (reviewing standards to excuse forfeiture); see also 16 U.S.C. 

§ 825l(b) (excusing failure to exhaust issues before the Commission when “there is reasonable 

ground for failure so to do”). 

The timing of PJM’s discovery that the Chairman acted alone readily qualifies for this 

exception. The remand motion stated that the “Commission” sought a voluntary remand and 

said nothing about the Chairman’s unilateral action. JA0884. The Commission’s traditional 

practice up until then had been to conduct a poll of the Commissioners before requesting a 

remand, and the Chairman never publicly announced that he had changed this policy before 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 11

filing the motion. PJM could not reasonably have discovered that the other Commissioners 

remained unaware of this departure from tradition when they themselves had not received notice. 

As soon as PJM learned about this unilateral action by the Chairman, it raised this issue in its 

petition for rehearing and gave the agency a chance to consider it. See 16 U.S.C. § 825l(b). On 

this record, PJM did not “sandbag[]” the agency or “strategically sle[ep] on its rights.” Jones 

Bros., Inc. v. Sec’y of Lab., 898 F.3d 669, 677 (6th Cir. 2018).

What about the statutory limit on our jurisdiction to review only an “order issued by the 

Commission,” 16 U.S.C. § 825l(b), not the D.C. Circuit’s remand order? It is true that the terms 

of the judicial-review statute do not authorize us to review the motion itself. And, of course, we 

may not review the D.C. Circuit’s order either. But the Commission addressed the Chairman’s 

authority to file the remand motion in its rehearing order and concluded that this step was within 

the Chairman’s statutory powers. The Commission determined that there was no legal defect in 

the process by which it reacquired jurisdiction from the D.C. Circuit. We may, of course, review 

the Commission’s order as it relates to this question of statutory interpretation.

Turning to the merits of PJM’s argument, the Commission maintains that the remand 

request does not require a quorum majority. Congress, it notes, has designated the Commission 

to be an agency under the Administrative Procedure Act, 42 U.S.C. § 7171(i), and it requires a 

majority vote only for agency “[a]ctions,” id. § 7171(e). Under the Administrative Procedure 

Act, it adds, “agency action” includes an agency’s rule, order, license, sanction, relief, or their 

equivalents and says nothing about motions to remand. 5 U.S.C. § 551(13). 

That reasoning might make sense if the Commission asked us to evaluate whether we 

could review the remand request under the Administrative Procedure Act. But this challenge 

focuses on whether the Commission has the authority to seek remand without a quorum majority. 

Congress did not use the phrase “agency action” in delineating the Commission’s authority. See 

16 U.S.C. § 825l(b); 42 U.S.C. § 7171(e). The Commission may undertake other actions that do 

not fall under the definition of “agency action” but still count as “action” in ordinary English. 

See, e.g., 16 U.S.C. § 824e(d) (power to investigate costs without setting rates); 42 U.S.C. 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 12

§ 7171(g) (power to hold hearings); id. § 7172(c) (power to consider proposals from the 

Secretary of Energy).

Switching gears, the Commission contends that Congress granted the Chairman authority 

to file a voluntary remand when it permitted him to act “on behalf of the Commission” for its 

“executive and administrative operation.” Id. § 7171(c). The scope of that authority is narrower 

than the Commission claims. As shown, these terms apply only to policies that the agency has 

already asked the Chairman to undertake. That explains why the Commission correctly concedes 

that, because the Chairman must exercise his authority “on behalf of the Commission,” id., he 

could not direct the Commission’s staff to advance a position “contrary” to Commission action 

adopted by majority vote, Respondent’s Br. 40. And that shows why the Chairman could not 

unilaterally seek remand of an issued order any more than he could confess error in a brief to our 

court without the Commission’s consent. 

What of the possibility that the agency receives deference when it comes to 

interpretations of ambiguous statutes? See Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc., 

467 U.S. 837, 843–44 (1984). But the ambiguity inquiry comes at the end, not the beginning, of 

the interpretive process. See id. at 843 n.9; Lechmere, Inc. v. Nat’l Lab. Rels. Bd., 502 U.S. 527, 

536–37 (1992). The relevant statutes, when viewed in context and after consideration of the 

relevant canons, are not sufficiently ambiguous to implicate Chevron. 

What of the risk that this interpretation of the statute will require courts to monitor every 

agency filing to ensure that a majority approved it? We see the point but think the statute 

implicates far fewer court filings than one might fear. Most agency filings and briefs will not 

require majority votes of multi-member agencies. Cf. 18 C.F.R. § 375.305 (delegating certain 

Commission filing duties to the Solicitor); id. § 375.309 (delegating certain investigative duties 

to General Counsel). But some substantive filings surely do. See 42 U.S.C. § 7172(a)(2) 

(permitting “the Commission” to determine when to exercise power in support of its 

jurisdiction). All can agree that the actual position of an agency—the order at issue—requires 

majority support. After that, substantive motions going to the enforceability of the order require 

actions of the Commission, not just the Chairman. Compare 16 U.S.C. § 825m(a), (c) 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 13

(permitting the Commission to use its discretion when suing and hiring attorneys to ensure 

compliance), with 18 C.F.R. § 375.311 (declining to delegate to the Director of the Office of 

Enforcement the Commission’s power to initiate enforcement suits). At a minimum, the 

Commission must support a decision about a motion to confess error, to reconsider an order, or 

to obtain a remand from a court to permit the agency to supplement or alter its decision—all 

matters about the enforceability or not of a pending order. 

This brings us to the question of remedy. We may invalidate an agency order that rests 

on legal error. See Sec. & Exch. Comm’n v. Chenery Corp., 318 U.S. 80, 94–95 (1943). The 

Commission considered the significance of the Chairman’s ultra vires act when PJM raised it in 

its petition for rehearing. The Commission concluded that the Chairman possessed the legal 

authority to request remand. That conclusion was incorrect. In denying rehearing, the 

Commission also gave no clear indication of how it would have responded to PJM’s petition if it 

had recognized that error, preventing us from severing that legal mistake from the rest of the 

rehearing order. See North Carolina v. FERC, 730 F.2d 790, 795–96 (D.C. Cir. 1984). 

We accordingly exercise our statutory authority “to affirm, modify, or set aside 

[a Commission’s] order in whole or in part” by vacating the part of the Commission’s order 

claiming the Chairman had this unilateral authority and for now leaving the rest of the 

challenged orders in place. 16 U.S.C. § 825l(b). We leave it to the Commission to decide in the 

first instance what, if anything, it could or would have done differently in response to this legal 

mistake. After the Commission resolves that point, any interested party may renew a petition to 

challenge that decision and to challenge any existing ratemaking orders on the grounds that they 

are arbitrary and capricious.

The dissent would go further and vacate the Commission’s orders in their entirety. The 

dissent reasons that we have no way to determine what the Commission would have done absent 

this unlawful action, and we cannot assume the agency would have started from scratch and 

issued the same remand order. We agree that the record does not establish what the Commission 

would have done had it recognized this legal error. But while the dissent traces this defect to the 

remand order, we view it as limited to the rehearing order. Recall that once the D.C. Circuit 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 14

returned the record to the Commission, the Commission regained the authority to revise its 

original order at will. See id. The decision to remand the record to the Commission belonged to 

the D.C. Circuit alone, and we cannot review our sister circuit’s decision by recalling and 

vacating the remand order. See 28 U.S.C. §§ 41, 43, 46. Because the record is silent on whether 

the Commission could or would have granted PJM’s request for a rehearing had it recognized 

that Chairman Glick exceeded his authority, we must vacate that part of the rehearing order and 

remand for further deliberation. See Burlington Truck Lines, Inc. v. United States, 371 U.S. 156, 

167–69 (1962).

We vacate the Commission’s rehearing order in part and remand for further proceedings 

consistent with this opinion.

DISSENT

_________________

CLAY, Circuit Judge, dissenting in part. The majority finds the Federal Energy 

Regulatory Commission (“FERC”) Chairman’s action to be unlawful, and then nevertheless 

leaves in place the results of his unlawful actions. Although I agree with the conclusion that the 

Chairman exceeded his statutory authority when he unilaterally requested a voluntary remand, 

the majority’s limited vacatur allows FERC to leave legal errors unresolved. Because the 

Chairman’s abuse of power cannot be dismissed as harmless, and thus necessitates some 

significant remedial action on FERC’s behalf, I would vacate the challenged 2021 orders in their 

entirety. Accordingly, I respectfully dissent in part from the majority’s opinion. 

I. BACKGROUND

Simplifying the technical background of this case, FERC made changes related to PJM 

Interconnection, LLC’s reserve market design after PJM submitted certain proposed revisions 

(the “2020 orders”).1 Following FERC’s decision and a change in presidential administration, 

the composition of FERC began to significantly change, and the lone dissenter from the 2020 

orders—FERC’s recently promoted Chairman—apparently decided to take advantage of this turn 

of events. Thus, while the 2020 orders were pending review in the D.C. Circuit, FERC’s 

Chairman, Richard Glick, unilaterally directed the agency’s Solicitor’s Office to move for a 

voluntary remand, effectively providing the Chairman with a second chance to secure the 

different outcome he desired. On remand, FERC reversed course from its 2020 orders, 

1Specifically, FERC adopted revisions to PJM’s market design that “raised the price cap for obtaining the 

minimum supply of reserves from $850/MWh to $2,000/MWh” and “reshaped the demand curve for additional 

reserves.” Pet’rs’ Br., ECF No. 75-1, 11. Because supply must exactly meet demand in the power grid, “reserve 

systems” are in place to meet peak levels of consumption. PJM is a FERC-regulated regional transmission 

organization that oversees this balance, and therefore successfully proposed certain revisions to the market design. 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 16

reinstating the original market design in a new order and affirming its decision by denying 

rehearing (the “2021 orders”).2 

The majority correctly concludes that Chairman Glick’s unilateral action exceeded his 

statutory authority. The Department of Energy Organization Act (the “DOE Act”) delineates the 

Commission’s and the Chairman’s powers and responsibilities in 42 U.S.C. § 7171(c) and (e). 

First, § 7171(c), which details the “Duties and Responsibilities of Chairman” provides that:

The Chairman shall be responsible on behalf of the Commission for the executive 

and administrative operation of the Commission, including functions of the 

Commission with respect to (1) the appointment and employment of hearing 

examiners in accordance with the provisions of title 5, (2) the selection, 

appointment, and fixing of the compensation of such personnel as he deems 

necessary, including an executive director, (3) the supervision of personnel 

employed by or assigned to the Commission, except that each member of the 

Commission may select and supervise personnel for his personal staff, (4) the 

distribution of business among personnel and among administrative units of the 

Commission, and (5) the procurement of services of experts and consultants. . . .

42 U.S.C. § 7171(c). Additionally, § 7171(e) provides that, “[t]he Chairman . . . shall preside at 

all sessions of the Commission and a quorum for the transaction of business shall consist of at 

least three members present. . . . Actions of the Commission shall be determined by a majority 

vote of the members present.” Id. § 7171(e).

These sections clearly indicate that only a majority vote can empower the Chairman to 

take any official action. Further, the Chairman’s expressly delineated duties are ministerial, 

rather than substantive. Indeed, “[c]ollective action is prerequisite to any alteration of a 

preexisting [FERC] order.” Pub. Serv. Comm’n of N.Y. v. Fed. Power Comm’n, 543 F.2d 757, 

776 (D.C. Cir. 1974). If Chairman Glick (or any Chairman, for that matter) could unilaterally 

reopen agency proceedings, such power would “wreak havoc on the stability of the agency’s 

decision.” Id. at 777. Based on this and the additional reasoning contained in the majority 

2Specifically, after the Chairman’s unlawful action securing voluntary remand, FERC reversed its 2020 

orders in December 2021. A few months later, in July 2022, FERC denied rehearing of this 2021 order. Because 

FERC initiated the reversal process in 2021, these two agency actions are collectively referred to as the “2021 

orders.”
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 17

opinion, I come to the same conclusion as the majority regarding Chairman Glick’s allotted 

power—he exceeded his statutory authority in seeking remand without a majority vote. 

However, unlike the majority, I would find that this error necessitates full, rather than 

partial, vacatur of the improperly decided 2021 orders. The majority’s contrary holding allows 

FERC the opportunity to claim that it would have come to the same conclusion regardless of the 

unlawful remand. Because FERC, in the unique circumstances of the instant case, cannot unring the bell or travel back in time to correct this serious error, vacating the product of its 

unlawful acts is the only way to honor the mandated, unambiguous decision-making process that 

Congress required by its passage of the DOE Act.

II. ANALYSIS

A. Partial Vacatur is Inappropriate in This Case

The majority acknowledges that “[t]he Commission considered the significance of the 

Chairman’s ultra vires act when PJM raised it in its petition for rehearing.” Maj. Op. at 13. But 

despite having the same statute and identical arguments before it, FERC reached the wrong 

conclusion, holding that the Chairman possessed the legal authority to unilaterally request 

remand. In addition, the majority correctly notes that FERC’s interpretation deserved no 

deference and did not implicate Chevron, inasmuch as the statute is “not sufficiently 

ambiguous.” Id. at 12 (citing Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc., 467 U.S. 837, 

843–44 (1984)). Because the statute at issue is unambiguous, the interpretation of 42 U.S.C. 

§ 7171 does not implicate changed circumstances or new law, and the ordinary remand rule does 

not apply. See, e.g., Negusie v. Holder, 555 U.S. 511, 523 (2009) (remanding because the 

agency had not yet exercised its discretion to interpret the statute in question); Prill v. NLRB, 

755 F.2d 941, 947 (D.C. Cir. 1985) (“An agency decision cannot be sustained, however, where it 

is based not on the agency’s own judgment but on an erroneous view of the law.”); INS v. 

Orlando Ventura, 537 U.S. 12, 16–17 (2002) (remanding to the BIA an unconsidered claim 

related to the changed circumstances in Guatemala). Therefore, this Court need not remand to 

the agency for it to apply its expertise and make a decision in the first instance—FERC already 

had that opportunity. However, despite FERC’s unquestionably erroneous interpretation, 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 18

the majority would extend to the agency an unwarranted opportunity to attempt a do-over by 

leaving the bulk of the 2021 orders in place.

Further, because FERC cannot reconsider and remedy some independent, severable issue 

from a procedurally correct larger opinion, this case does not present the usual circumstances 

warranting partial vacatur. See, e.g., Murillo Morocho v. Garland, 80 F.4th 61, 63 (1st Cir. 

2023) (vacating in part and remanding for further proceedings because the BIA applied the 

incorrect legal standard to one prong of petitioner’s Convention Against Torture claim); Carlson 

v. Postal Regul. Comm’n, 938 F.3d 337, 399 (D.C. Cir. 2019) (vacating the Commission’s order 

in part and noting that the court could leave in place the portions of the order that “[were] not 

interconnected” to the offending parts of the rule and “analyzed [] independently”); Sierra Club 

v. FERC, 867 F.3d 1357, 1366 (D.C. Cir. 2017) (noting that the evaluation of an agency order’s 

severability for vacatur-in-part turns on whether “there is substantial doubt that the agency would 

have adopted the same disposition regarding the unchallenged portion [of the order] if the 

challenged portion were subtracted” and declining to merely vacate in part (citation omitted)); 

Davis Cnty. Solid Waste Mgmt. v. U.S. EPA, 108 F.3d 1454, 1460 (D.C. Cir. 1997) (vacating in 

part because the “severance of standards for small units and cement kilns ‘will not impair the 

function of [the other standards] . . . and there [was no] indication that the regulation would not 

have been passed but for [the] inclusion’ of the standards for small units and cement kilns.” 

(brackets in original) (quoting K Mart Corp. v. Cartier, Inc., 486 U.S. 281, 294 (1988))). Unlike 

the cases in which an isolated portion of the agency’s decision was severable, the Chairman’s 

illegal actions in the instant case affected both the procedure and the substance of the 2021 

orders, permeating the entirety of the agency’s analysis. As the majority concedes, this Court 

cannot separate the error that occurred from the substantive outcome of the 2021 orders, 

distinguishing this case from those cases that are sometimes vacated in part.

After agreeing that we cannot assume that FERC would have issued the same 2021 orders 

absent the recognized error, the majority nevertheless refrains from full vacatur to avoid 

“recalling and vacating [the D.C. Circuit’s] remand order.” Maj. Op. at 14. But we would not be 

“recalling” or “vacating” the D.C. Circuit’s order. In fact, the D.C. Circuit’s order granting 

FERC’s voluntary remand request is not even before this Court. Contrary to the majority’s 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 19

argument, this Court’s job is certainly not to vacate the D.C. Circuit’s order granting remand, but 

rather to appropriately fashion a remedy that addresses the agency’s errors presented to this

Court within this appeal. Cf. Nixon v. Kent County, 76 F.3d 1381, 1388 (6th Cir. 1996) (en banc) 

(citing Atchison, Topeka & Santa Fe Ry. v. Pena, 44 F.3d 437, 443 (7th Cir. 1994) for the 

proposition that the Court’s duty is to independently decide our own cases without constraint 

from our sister circuits). The record has been placed back into FERC’s hands by the D.C. 

Circuit, and vacating FERC’s improperly decided 2021 orders would not change that outcome. 

Instead, full vacatur properly demands agency accountability for FERC’s flagrant error, 

requiring some additional analysis and action beyond merely considering “what, if anything, it 

could or would have done differently.” Maj. Op. at 13. 

Nonetheless, the majority forgoes instituting a remedy that would adequately address the 

illegality of the Chairman’s actions, instead opting to punt the unresolved question to the agency 

that, for whatever reason, failed to interpret the eminently clear statute correctly in the first place. 

With the issues before it fully briefed, FERC previously had its opportunity to correct the error in 

this case but chose not to. By explicitly opening the door to FERC’s future inaction or legal 

error and leaving the tainted 2021 orders in place, the majority hands the agency yet another

chance to avoid the elimination of the grave error that placed this case before this Court. 

B. Harmless Error in the Administrative Law Context

To evaluate why FERC cannot simply leave the 2021 orders standing, a brief overview of 

harmless error is warranted. See Carlson, 938 F.3d at 351 (explaining that the APA permits a 

reviewing court to set aside “part of an agency order” when: (1) the agency would have adopted 

the same disposition regarding the remainder of the order even if the unlawful portion were 

subtracted, and (2) the remaining parts function sensibly without the stricken provision). The 

harmless error doctrine may be employed in the administrative law context “when a mistake of 

the administrative body is one that clearly had no bearing on the procedure used or the substance 

of the decision reached.” Nat. Res. Def. Council v. U.S. Forest Serv., 421 F.3d 797, 807 (9th Cir. 

2005) (emphasis in original) (citation omitted); see also United States v. Utesch, 596 F.3d 302, 

312 (6th Cir. 2010) (“[A] reviewing court must focus not merely on the ultimate rule but on the 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 20

process of an administrative rulemaking.”).3 Various courts have evaluated harmless error in the 

administrative law context using slightly different standards, depending upon whether the error 

at issue is properly characterized as more procedural or substantive. The harmless error inquiry 

for substantive errors usually focuses on whether the agency would have reached the same result 

absent an error,4 while the inquiry for procedural errors usually evaluates whether an error 

prevented specific facts or arguments from being presented to an agency.5 Although the caselaw 

explaining the harmless error analysis’ application to the administrative law context varies, 

Chairman Glick’s error fails the test on all fronts.

Importantly, harmless error must be applied with caution in the administrative law 

context. Cal. Wilderness Coal. v. U.S. Dep’t of Energy, 631 F.3d 1072, 1090 (9th Cir. 2011). If 

the harmless error rule were to only take account of results, an agency could always claim that it 

would have adopted the same rule even if it had complied with the proper procedures. Riverbend 

Farms, Inc. v. Madigan, 958 F.2d 1479, 1487 (9th Cir. 1992). In other words, agency leaders 

could act before heeding administrative procedures, effectively asking for forgiveness rather than 

permission and leaning on the incumbent members to later agree that they surely would have 

adopted the same rule all along. In this case, the failure to obtain a quorum was not some 

technical error, but “resulted in a decision-making process that was contrary to that mandated by 

Congress.” Cal. Wilderness Coal., 631 F.3d at 1095. Thus, to avoid gutting the procedural 

requirements carefully delineated in the DOE Act, the harmful error analysis in the 

administrative law context must focus on both the process and the result.

Airways v. Civ. Aeronautics Bd., 379 F.2d 453, 466 (D.C. Cir. 1967) (same); Mass. Trs. of E. Gas & Fuel Assocs. v. 

United States, 377 U.S. 235, 248 (1964) (same); U.S. Steel Corp. v. U.S. EPA, 595 F.2d 207, 215 (5th Cir. 1979)

making comments on the proposed permit application).

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 21

C. Application to Chairman Glick’s Unilateral Action

The question in this case is whether the Chairman’s unilateral action had any bearing on 

the procedure used or the substance of FERC’s 2021 orders. Because Chairman Glick’s action 

certainly affected both procedure and substance, the majority’s limited vacatur is improper. 

Importantly, as FERC considers the proper action to take on remand, leaving the 2021 orders 

standing through inaction is not a viable option. In this case, the harmless error analysis can be 

viewed through two lenses: absent the Chairman’s unlawful action, (1) would the Commission 

have nonetheless voted to voluntarily remand had a quorum actually voted, and (2) would the 

Commission have nonetheless substantively decided the 2021 orders in the same way. The 

answer to both of these questions is unclear, indicating that there are irreparable errors in both 

the process and the result.

Addressing these harmless error questions in chronological order, this Court cannot 

speculate as to how a quorum would have voted regarding a voluntary remand. After all, despite 

his or her political or substantive inclinations, a commissioner may vote against voluntary 

remand because remands can involve years of additional proceedings, require high litigation 

costs, and disturb the stability of the policymaking process. See Joshua Revesz, Voluntary 

Remands: A Critical Reassessment, 70 Admin. L. Rev. 361, 370–80 (2018) (exploring reasons an 

agency may desire or decline to voluntarily remand). Furthermore, at the time Chairman Glick 

should have taken the vote, two out of five of the Commission members likely would not have 

moved for remand, based on their prior votes in the 2020 orders.

6

 Thus, if only three members 

are required to constitute a quorum, one could not readily conclude that Chairman Glick would 

have been able to secure the requisite votes.7 This procedural error was far from harmless, as it 

6Commissioner Danly and Commissioner Chatterjee, both of whom were in the majority for the 2020 

orders, remained on the Commission at the time Chairman Glick unilaterally remanded the case. Therefore, it is 

likely that they would not agree to a voluntary remand to reconsider their own decision.

7For these same reasons, any ratification argument also fails. Although a principal may validly sanction 

the prior action of its purported agent, the party ratifying must “be able not merely to do the act ratified at the time 

the act was done, but also at the time the ratification was made.” Fed. Election Comm’n v. NRA Pol. Victory Fund, 

513 U.S. 88, 98 (1994) (emphasis in original) (citing Cook v. Tullis, 85 U.S. 332, 338 (1873)); see also Restatement 

(Second) of Agency § 90 cmt. a (1958) (“The bringing of an action, or of an appeal, by a purported agent cannot be 

ratified after the cause of action or right to appeal has been terminated by lapse of time.”). By the time the 

Commission “ratified” Chairman Glick’s unlawful voluntary remand by voting on the 2021 orders, the D.C. Circuit 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 22

prevented Petitioners from challenging the voluntary remand, likely influenced the content of the 

voluntary remand request itself, and led to a further substantive error.

Turning to an explanation of the substantive error resulting from FERC’s unlawful 

review, it is also unclear whether FERC would have overturned the 2020 orders using the only 

other standard applicable to evaluating a final agency order. Specifically, there are only two 

ways by which an agency can reconsider a final order.8 The first option is employing the unique 

voluntary remand mechanism, as courts frequently grant voluntary remands to preserve judicial 

resources. See, e.g., Ethyl Corp. v. Browner, 989 F.2d 522, 524 (D.C. Cir. 1993) (“We 

commonly grant such [voluntary remand] motions, preferring to allow agencies to cure their own 

mistakes rather than wasting the courts’ and the parties’ resources. . . .”). By invoking the 

benefits of a voluntary remand, the agency can consider its original decision with fresh eyes—in 

other words, FERC can begin with a blank slate and completely rework the merits of its 2020 

orders by reassessing PJM’s initial proposals. 

However, without a valid voluntary remand (as in this case), agencies must employ 

Section 206 of the Federal Power Act to challenge a final order. 16 U.S.C. § 824e. Under 

Section 206, FERC would bear the burden of showing that the document on file at the time, the 

2020 order, was unjust and unreasonable. See Emera Me. v. FERC, 854 F.3d 9, 26 (D.C. Cir. 

2017) (noting that a Section 206 proceeding requires FERC to bear the burden of making an 

explicit finding that the existing rate was unlawful before it was authorized to set a new lawful

rate). In order to enhance decision-making stability and to prevent agencies from locking their 

decisions in a perennial revolving door, the Section 206 burden is a stringent one. Therefore, the 

2021 orders cannot be left in place, as FERC’s current members cannot speculate as to the 

could have ruled upon the arbitrariness of the 2020 orders, making the 2020 orders final and thus requiring FERC to 

employ Section 206. Alternatively, the D.C. Circuit could have declined to grant the voluntary remand motion later 

in the timeline of the proceedings. See, e.g., Miss. River Transmission Corp. v. FERC, 969 F.2d 1215, 1217 n.2 

(D.C. Cir. 1992) (denying a voluntary remand motion made a few days before oral argument). Once again, we may 

never know.

8The 2020 orders in this case are final because once the record was filed in a court of appeals, the 

Commission lost its power to correct or change the orders, as jurisdiction had passed to the court. 

See 16 U.S.C.§ 825l(a); see also Hirschey v. FERC, 701 F.2d 215, 217–18 (D.C. Cir. 1983). 
Nos. 22-3176/3666/

3794/3796

Electric Power Supply Ass’n, et al. v. FERC Page 23

manner in which the then-members would have ruled had the higher Section 206 standard been 

employed.

Not only would a higher standard potentially change the ultimate outcome, but, at the 

very least, the content of the opinion would be extremely different, as a finding that the 2020 

order was unjust and unreasonable would necessitate further analysis. See, e.g., Int’l 

Transmission Co. v. FERC, 988 F.3d 471, 485–86 (D.C. Cir. 2021) (recognizing petitioner’s 

argument that “even if FERC had paid lip service to Section 206’s requirements, its analysis 

could not support its finding that the existing [rates] were unjust or unreasonable.” (internal 

quotations omitted)); Emera, 854 F.3d at 27 (explaining that FERC must undertake additional 

analysis to satisfy the dual burden of Section 206). To put this standard into a different, more 

accessible context, suppose that the price of coffee became regulated. Coffee consumers may 

believe that a reasonable price for coffee ranges anywhere from $1.00 to $10.00 per cup. See 

Me. Pub. Utils. Comm’n v. FERC, 520 F.3d 464, 471 (D.C. Cir. 2008) (explaining that “there is 

not a single just and reasonable rate,” but rather a “zone of rates that are just and reasonable.”). 

In this coffee hypothetical, suppose a coffee company proposed a price cap somewhere in this 

range. Clearly, a finding that the proposed price cap is just and reasonable is not equivalent to a 

finding that the proposed price cap is unjust and unreasonable—the latter finding involves 

significantly more analysis, as the former may be proved by merely recognizing that the proposal 

falls within the reasonable zone of $1.00 to $10.00. While divining what exactly FERC would 

have held under a Section 206 standard may be a fruitless task, it is certainly extremely likely 

that the substance of the opinion would change.

Further, FERC agrees that a different, more lenient standard applied due to the unlawful 

remand. Instead of explaining why Petitioners are not prejudiced by this different standard, 

FERC tellingly argues that Petitioners forfeited this argument. This argument is not convincing, 

as Petitioners’ rehearing application does explain that Chairman Glick exceeded his lawful 

authority in requesting the remand. Furthermore, FERC seems to misunderstand Petitioners’ 

argument regarding prejudice, as each of its subsequent arguments rely on the premise that 

Petitioners are arguing that the voluntary remand process is unlawful altogether. Not so—

Petitioners solely argue that this unilateral remand in particular circumvents Section 206’s

standards. Had Chairman Glick properly convened a quorum that had voted to voluntarily 

remand, there would be no argument that a different standard should apply. 

While contradictorily stating that the legal mistake in this case is inseverable from the 

underlying 2021 orders, the majority nonetheless incorrectly concludes that a limited vacatur 

would redress these errors. Maj. Op. at 13–14. As explained above, the voluntary remand is a 

powerful tool that had an immense impact on the 2021 orders, as the lower burden applied on 

remand effectively circumvented the requirements of Section 206. Concisely, without the 

unlawful remand, we have no idea what FERC’s conclusion would have been. Accord Maj. Op. 

at 13 (“We agree that the record does not establish what the Commission would have done had it 

recognized [its] legal error.”). Our job is to evaluate the question of whether the unlawful 

unilateral remand had any “bearing on the procedure used or the substance of the decision 

reached.” Nat. Res. Def. Council, 421 F.3d at 807. In this case, the answer is unequivocally yes, 

and the unlawful byproducts of the Chairman’s actions must be vacated in full. The errors that 

FERC made in promulgating the 2021 orders infected the substance of the orders, requiring their 

complete invalidation.

The majority sanctions a mere slap on the wrist, stating that upon remand, FERC can 

determine “what, if anything, it could [] have done differently.” Maj. Op. at 2, 13. However, 

Chairman Glick should not be able to reap the benefits of a less stringent standard of review 

resulting from his improper action, and this Court should not issue a decision that allows agency 

leaders to “ask for forgiveness rather than permission,” armed with the understanding that real 

consequences will not result from their actions. Effectively, Chairman Glick’s actions allowed 

the agency not only to avoid litigating the case on the merits in the D.C. Circuit, but also to 

circumvent the more demanding standard that would apply to a challenge of a final agency 

opinion. Such action cannot be harmless, and this Court should not provide FERC with a 

loophole to avoid addressing a very substantial error. For these reasons, FERC should not be 

permitted to sit back and do nothing upon remand.

III. CONCLUSION

Unlike the majority, I would vacate the 2021 orders because Chairman Glick’s unilateral 

remand clearly “had [a significant] bearing on the procedure used or the substance of the 

decision reached,” and the resulting error is inseverable from the orders. Nat. Res. Def. Council, 

421 F.3d at 807; see also Douglas Timber Operators, Inc. v. Salazar, 774 F. Supp. 2d 245, 260 

(D.C. Cir. 2011) (holding that the “Secretary lacked inherent authority” and holding that such 

error “constitute[d] a procedural error of sufficient gravity for the court of appeals to have opted 

for vacatur”); Cal. Wilderness Coal., 631 F.3d at 1095 (rejecting partial vacatur where “it [was] 

almost impossible to determine the precise impact of [the procedural error]”). We will never 

know if the then-current Commission would have voted to voluntarily remand the agency record 

from the D.C. Circuit. Likewise, we will never know if the D.C. Circuit would have granted 

remand had the request been made later in the proceedings. Finally, the procedural error in the 

way the voluntary remand was requested could have led to significant substantive errors, as the 

outcome from applying Section 206 could vastly differ from the current 2021 orders. For these 

reasons, there is substantial doubt that FERC would have evaluated the remainder of the orders 

in the same manner or reached the same disposition, and partial vacatur is, therefore, 

inappropriate. Carlson, 938 F.3d at 351. However, to correct the Chairman’s unlawful action, 

we can ascertain how FERC would rule on the 2020 orders under Section 206—the only other 

way for the agency to challenge an order that had been turned over to the courts. 

Judicial review is intended to provide a meaningful forum for reviewing agency actions 

to correct error, yet the majority shies away from providing any meaningful relief. We should 

not leave in place a rule that the agency never properly promulgated. In order to minimize the 

error of Chairman Glick’s solo endeavors in this unique situation, I would vacate the challenged 

2021 orders and remand for further proceedings consistent with this opinion. Upon remand, 

FERC would, of course, have the option to challenge the 2020 orders in a manner that accords 

with Section 206. Rather than forcing interested parties to comply with orders that this Court has 

found to be erroneous, I would require that FERC take accountability for its past mistakes. 

I therefore respectfully dissent in part.
