ARGUMENT
The Secretary’s1 Brief in Opposition (“Opp.”) cannot
overcome Petitioners’ three reasons why review should
be granted:
• The Panel’s Decision defies this Court’s holding
in U.S. Parole Comm’n v. Geraghty, 445 U.S. 388
(1980), that named plaintiffs in a class action retain
an Article III interest in representing the class
sufficient to appeal a denial of class certification
even if their individual claims are made moot after
that denial. To let the Decision stand would reward
disregard of this Court’s precedent and erode the
longstanding principle that lower courts must follow
such precedent unless this Court holds otherwise.
• The Panel’s Decision intentionally creates a circuit
split, as the Secretary concedes, which, unless
resolved, will leave one law for class actions brought
in the D.C. Circuit, including many against the
federal Government, and another for everywhere
else.
• The Panel’s Decision imperils the class action
device by allowing defendants, including the federal
Government, to negate standing by picking off
named plaintiffs over their objection by paying their
individual claims.
In suggesting this case is not the right vehicle for correcting
these fundamental errors, the Secretary mistakenly
1. This Reply uses terms defined in the Petition.
2
assumes a) that Petitioners have no continuing personal
stake in the litigation, when they retain an independent
stake in representing the class and where their counsel
retains a contingent fee interest in the outcome; b) that
only 17 class members have possible claims, when many
thousands indisputably do, because the filing of a class
action suspends the statute of limitations for all pending
claims of class members as of the filing date, and c) that
the case is unimportant because the Government changed
its policy (prospectively only), which failed to remedy
the harm from its 10-year practice (from 2012-2022) of
denying Medicare CGM coverage for Type 1 diabetics on
the specious ground that CGMs were not primarily used
for a medical purpose.
The Panel’s Intentional Disregard Of Geraghty Warrants
Review
The Secretary’s Opposition reinforces the importance
of granting review. The Secretary erroneously presumes
Geraghty does not reflect current law. Because it does
unless this Court holds otherwise, the Panel made a
grievous error, which will have an outsized impact negating
the viability of class actions, particularly those against the
federal Government, and should be immediately rectified.
Geraghty recognizes that named plaintiffs in class
actions have two Article III interests: first, in their
individual claim and, second, in representing absent
members. 445 U.S. at 402. The Panel erroneously declared
that Geraghty’s recognition of this second interest does
not reflect current law. The Secretary strives to identify
grounds for letting this erroneous ruling stand. None
provide any basis for denying review.
3
The Panel’s holding that Petitioners lack standing to
appeal the class certification denial because judgment
was subsequently entered in their favor conflicts with
Geraghty’s holding that “a proposed class representative
who proceeds to judgment on the merits may appeal denial
of class certification.” 445 U.S. at 399 (emphasis original).
The Secretary posits that Geraghty concerned mootness,
while Petitioners’ claims were satisfied through payment,
yet this demonstrates no meaningful distinction because
payment is one way to create mootness. E.g., Mann Const.,
Inc. v. United States, 86 F.4th 1159, 1163 (6th Cir. 2023)
(IRS refund and abatement of penalties mooted refund
claim). Geraghty’s reasoning applies to both situations.
The Secretary erroneously argues that Panel’s
Decision does not conflict with Geraghty because this
Court’s recognition of a “right to have a class certified if
the requirements of the Rules are met,” allegedly “has
been undermined by subsequent case law.” (Opp. 10).
That premise confirms that the Panel’s Decision conflicts
with Geraghty. Moreover, it presumes the Panel correctly
disregarded Geraghty’s holding, which assumes the
erroneous answer to the question Petitioners are asking
this Court to decide.
Geraghty recognized that “[a] plaintiff who brings
a class action presents two separate issues for judicial
resolution. One is the claim on the merits; the other is
that he is entitled to represent the class.” Id. at 402
(emphasis added). Geraghty stressed these are distinct
Article III interests. Geraghty explained that “‘a district
court’s final judgment fully satisfying named plaintiffs’
private substantive claims would preclude their appeal
on that aspect of the final judgment; however, it does not
4
follow that this circumstance would terminate the named
plaintiffs’ right to take an appeal on the issue of class
certification.’” Id. (citing Deposit Guaranty National
Bank v. Roper, 445 U.S. 326, 333 (1980)). Geraghty’s
recognition that named plaintiffs retain this interest even
after their individual claims were “fully satisfied” shows
they need not have their own ongoing economic interest
to have standing to appeal a class certification denial, as
the Panel erroneously held.
The Secretary acknowledges that Geraghty grounded
the named plaintiff ’s standing in the relation-back
principle, a traditional Article III concept. (Opp. 11).
Under that principle, “when a District Court erroneously
denies a procedural motion, which, if correctly decided,
would have prevented the action from becoming moot,
an appeal lies from the denial and the corrected ruling
‘related back’ to the date of the original denial.” 445 U.S.
at 404 n.11. Applied here, Petitioners had standing when
the District Court denied class certification, because the
Secretary only agreed to pay Petitioners’ claims and
moved for summary judgment after certification was
denied. 2
Instead, the Secretary argues the principle does not
apply because Geraghty left unresolved whether named
plaintiffs who settle their individual claims retain standing.
(Opp. 11) (citing Geraghty, 445 U.S. at 404 n.10). This is
a non sequitur: Petitioners did not settle their claims;
judgment was entered in their favor over their objection.
2. In Genesis Healthcare Corp. v. Symczyk, 569 U.S. 66, 75
(2013), this Court relied on Geraghty’s relation-back analysis to
distinguish class actions from FLSA collective actions.
5
The relation-back principle is particularly relevant
to standing, which considers a plaintiff’s interest when
suit commences. See Arizonans for Official English
v. Arizona, 520 U.S. 43, 68 n.22 (1997). Nevertheless,
the Secretary argues that Geraghty should only apply
where claims are “inherently transitory,” such as where
trial courts lack time to rule on class certification before
mootness occurs. (Opp. 9) (citing 445 U.S. at 397). Yet
Geraghty rejected this limitation, holding “the class action
aspect of the mootness doctrine does not depend on the
class claim’s being so inherently transitory that it meets
the ‘capable of repetition, yet evading review,’ standard.”
Id. at 398 n.6 (citation omitted).
Separate from the relation-back principle, Geraghty
held that a named plaintiff has an Article III stake in
representing the class under the “Private Attorney
General” concept, noting the benefits that a named
representative receives “generally are byproducts of
the class-action device.” 445 U.S. at 403. This belies the
Secretary’s contention that Petitioners would not benefit
directly if class members were fully paid, as that would
fulfill their mission as class representatives.
While the Secretary characterizes the denial of class
certification as a “bare procedural violation divorced from
any concrete harm,” (Opp. 11), Geraghty held otherwise:
The purpose of the ‘personal stake’ requirement
is to assure that the case is in a form capable
of judicial resolution. The imperatives of a
dispute capable of judicial resolution are
sharply presented issues in a concrete factual
setting and self-interested parties vigorously
6
advocating opposing positions. We conclude
these elements can exist with respect to the
class certification issue notwithstanding the
fact that the name plaintiff’s claim on the merits
has expired.
445 U.S. at 403. 3
Geraghty reaffirmed Coopers & Lybrand v. Livesay,
437 U.S. 463, 469-70 (1978) (cited 445 U.S. at 399-400),
where this Court rejected the necessity of interlocutory
appeal as of right for class certification denials because of
the “prospect of prevailing on the merits and reversing”
a class certification denial. The Panel Decision eliminates
this prospect.
Review should be granted to correct the Panel’s
departure from this Court’s controlling precedent in
Geraghty.
3. The cases the Secretary cites to argue that Geraghty
no longer reflects current law do not concern appeals of class
certification denials. See Opp. 11-12 (citing TransUnion LLC
v. Ramirez, 594 U.S. 413, 433-39 (2021) (finding subset of class
suffered no concrete injury and lacked standing); Spokeo, Inc.
v. Robins, 578 U.S. 330, 338-43 (2016) (remanding standing
determination where record left unclear whether procedural
violation caused named plaintiff concrete injury); Summers v.
Earth Island Institute, 555 U.S. 488, 495 (2009) (environmental
group member could not show particular timber sale which
threatened injury, precluding standing); Lujan v. Defenders of
Wildlife, 504 U.S. 555, 562-63 (1992) (environmental group showed
no risk of imminent harm, precluding standing).
7
The Panel Misconstrued This Court’s Decision In Roper,
Further Supporting Review
The Secretary tries to drive an illusory wedge
between Geraghty and Roper, wrongly suggesting the
latter requires a named plaintiff to retain a personal
interest separate from the interest representing the class
to appeal a class certification denial. This ignores that
they were companion cases, decided the same day and that
Geraghty relies heavily on Roper. Read correctly, Roper
holds that an individual economic interest is sufficient to
support standing to appeal certification denials but not
required. Otherwise, as here, defendants can sequentially
pick off named plaintiffs by paying their individual claims.
Roper emphasized that “a district court’s ruling on
class certification is often the most significant decision
rendered in these class action proceedings.” 445 U.S. at
339.
To deny the right to appeal simply because the
defendant has sought to “buy off” the individual
private claims of the named plaintiffs would
be contrary to sound judicial administration.
Requiring multiple plaintiffs to bring separate
actions, which effectively could be “picked off”
by a defendant’s tender of judgment before an
affirmative ruling on class certification could
be obtained, obviously would frustrate the
objectives of class actions.
Id. at 339.
Geraghty echoed this, stating: “And today, the Court
holds that named plaintiffs whose claims are satisfied
8
through entry of judgment over their objections may
appeal the denial of a class certification ruling.” 445 U.S.
at 400. To let the Panel Decision stand would do what
Geraghty and Roper forbid by foreclosing Petitioners’
right to appeal because the Secretary “picked off” their
individual claims.
Roper recognized there are broad interests “to be
considered when questions touching on justiciability
are presented in the class-action context,” including
the named plaintiffs’ “right ... to employ in appropriate
circumstances the procedural device of a Rule 23 class
action to pursue their individual claims,” along with a
“separate consideration, distinct from [named plaintiffs’]
private interests”––“the responsibility of named plaintiffs
to represent the collective interests of the putative class.”
445 U.S. at 331.
Geraghty held that the interest in representing the
class was the same in both cases, stating that “Geraghty’s
‘personal stake’ in the outcome of the litigation is, in a
practical sense, no different from that of the putative
class representatives in Roper.” Id. at 401. Additionally,
both decisions relied on the private attorney general
concept in addressing standing, recognizing that the
financial incentives offered to the legal profession by class
actions under Rule 23 “[are] a natural outgrowth of the
increasing reliance on the ‘private attorney general’ for
the vindication of legal rights.” 445 U.S. at 338.
Finally, the Secretary suggests Roper is distinguishable
from Geraghty because Roper held that a fee-shifting
arrangement was sufficient to establish the named
plaintiff’s continued economic interest in representing
9
the class. (Opp. 6, 16). However, the Panel rejected that
fee-shifting arrangements, alone, can support standing.
(Pet.App.9a). Thus, if the Panel Decision stands, the
D.C. Circuit will not apply Roper as even the Secretary
recognizes it should.
This Court Should Resolve The Circuit Split That The
Panel Decision Creates
Granting review will resolve the conflict the Panel
Decision intentionally creates with Jin v. Shanghai
Original, Inc., 990 F.3d 251 (2d Cir. 2021), Reed v. Heckler,
756 F.2d 779 (10th Cir. 1985), Culver v. City of Milwaukee,
277 F.3d 908 (7th Cir. 2002).4 The Panel’s Decision is a
rogue outlier that should not be left enforceable in the
D.C. Circuit.
By incentivizing defendants to pick off named
plaintiffs, the Panel’s Decision makes it easier to
thwart appeals of denials of class certification. This will
disproportionately affect class actions against the federal
Government, which are often filed in D.C. District courts.
Because federal agencies often apply policies nationally,
the Panel’s error will also have nationwide repercussions.
Jin is recent and true to Geraghty and Roper. There,
the Second Circuit held a named plaintiff could appeal
denial of class certification despite having no ongoing
financial interest because he had already obtained
4. As the Petition notes, both Cameron-Grant v. Maxim
Healthcare Servs., Inc., 347 F.3d 1240, 1245-49 (11th Cir. 2003),
and Lusardi v. Xerox Corp., 975 F.2d 964, 975-80 (3d Cir. 1992),
applied Geraghty to hold that named plaintiffs lacked standing to
appeal and also are in conflict. (Pet. 33, 35).
10
damages, attorney’s fees and costs. 990 F.3d at 259. The
court reasoned, “neither we nor the Supreme Court have
required that to satisfy personal stake in the context of a
named plaintiff appealing the denial of class certification
following a favorable judgment on the merits at trial.”
Id. It found that plaintiff had a personal stake “akin to
the interest of a private attorney general that sufficed in
Geraghty.” Id. The Secretary suggests Jin is inconsistent
with “modern standing doctrine,” (Opp. 14), another way
of saying it correctly followed Geraghty.
The Secretary acknowledges that Reed conflicts
with the Panel’s decision but tries to distinguish it as
extending Geraghty. To extend Geraghty, Reed first had
to accept it as good law. Moreover, the alleged “extension”
was to circumstances where named plaintiffs received a
favorable judgment from an agency. So here, the Secretary
agreed to pay Petitioners’ claims and moved for summary
judgment in their favor.
Culver permitted a named plaintiff whose individual
claim was inadequate and moot to appeal decertification.
277 F.3d at 910. The Secretary argues that the mootness
of named plaintiff’s claim there makes Culver inapplicable,
because Petitioners’ claims were paid, an argument
refuted above.
This Court Should Remove The Threat The Panel Decision
Poses To Class Actions.
The Court should grant review to negate the critical
danger the Decision poses to the viability of the class
action device. If the Decision stands, it will imperil all
class actions by providing defendants (especially the
Government) with a blueprint of how to terminate a class
11
action over named plaintiffs’ objections: pay the named
plaintiffs and move for summary judgment on their claims
and, if they are replaced, do likewise with every successor.
Fee shifting arrangements would not prevent this, and
even if they could, a defendant could circumvent this by
specifying an intent to pay fees in any motion or offer of
judgment, eliminating the prospect of fee recovery as an
ongoing economic interest.
This Is The Right Case To Resolve The Questions Presented.
The Secretary urges this Court to ignore the Panel’s
disregard of this Court’s precedent, the Panel’s knowing
creation of a circuit split, and its assault on the class
action device by suggesting this may not the right case
for remedying these issues. Because the Panel’s Decision
is the sole source of these problems, this is the right case
to resolve them.
A. Petitioners Have An Ongoing Personal Stake In
Representing The Class.
The Secretary erroneously reframes the question
presented as involving circumstances where “plaintiffs
disclaimed any continuing personal stake in the litigation.”
(Opp. (I)). Rather, consistent with Geraghty and Roper,
Plaintiffs argued they maintained an Article III interest
in representing absent class members that continued after
the Secretary obtained judgment for Petitioners after
picking off their individual claims over their objection.
While the Secretary argues that Petitioners had no
fee-sharing arrangement (Opp. 6), this overlooks that
Petitioners’ counsel represents the entire class under a
contingent fee arrangement, as generally occurs in class
actions. The Panel erroneously disregarded this.
12
B. The Class Has 90,000+ Members, Not 17.
To minimize this case’s importance, the Secretary
suggests that review be denied because the District
Court correctly found the class lacks numerosity because
only 17 possible class members exhausted administrative
remedies or sued within the statute of limitations. This
perpetuates a legal error that Petitioners directly
challenged on appeal, but the Panel never considered.
The class consists of 90,000+ Type 1 diabetics whose
claims for CGM coverage were denied between 2012 and
2022. In denying class certification, the District Court
improperly considered the above “affirmative defenses,”
even though the Secretary, whose burden it was to plead
defenses, pleaded none. The District Court prematurely
and erroneously found the affirmative defenses of
exhaustion and limitations would bar all claims that
had not reached the District Court. However, because
the Secretary made false representations to a large
percentage of the class about why claims were denied,
equitable estoppel could have negated these defenses
even had they been properly raised. See Bowen v. City
of New York, 476 U.S. 467 (1986) (holding “courts may
excuse a beneficiary’s failure to exhaust”). Moreover,
the commencement of a class action suspends the statute
of limitations as to all class members, see American
Pipe & Const. Co. v. Utah, 414 U.S. 538, 553-54 (1974),
meaning the class properly includes the many thousands
of Medicare claimants whose CGM claims were pending at
any level of Agency review when suit was filed. Medellin v.
Shalala, 23 F.3d 199, 202-03 (8th Cir. 1994). The District
Court had no discretion to find otherwise.
13
C. The Panel’s Errors Will Undermine Class Actions
Unless Redressed
The Secretary cites Judge Pillard’s concurrence in
denial of rehearing that HHS’ 2022 policy change means
this case will have only limited precedential impact, yet
this was incorrect. First, it ignores the negative impact
that leaving the Panel’s errors unredressed would have on
all future class actions in federal court. Second, it ignores
that there are 90,000+ class members whose CGM claims
from 2012-22 remain unpaid here whose injuries deserve
redress. Class actions routinely address past rather
than ongoing harm. Moreover, virtually all diabetic class
members lack the resources to pursue individual Medicare
appeals if denial of certification here stands.
