2 FALLON V. DUDEK
SUMMARY **
Social Security / Law of the Case
The panel affirmed the district court’s decision affirming
an Administrative Law Judge’s denial of an application for
Supplemental Security Income (SSI) under the Social
Security Act, and refusing to reconsider some of the medical
evidence following its initial remand to the agency for
further proceedings.
In the first decision, the district court found that the ALJ
properly discounted Dr. Drazkowski’s and LPC Galler’s
opinions, but concluded that the ALJ erred in discounting the
remaining witnesses and remanded for further consideration
of the record. On remand, the ALJ again found claimant not
disabled, incorporating by reference the prior ALJ’s
undisturbed evaluations, including Dr. Drazkowski’s and
LPC Galler’s opinions. In the second decision, the district
court scrutinized the ALJ’s new findings, but refused under
the law-of-case doctrine to revisit its prior conclusions about
Dr. Drazkowski’s and LPC Galler’s opinions.
The panel rejected claimant’s contention that law of the
case did not apply because under the Social Security Act the
district court’s two decisions (before and after remand) were
not issued in the same “case.” The law-of-the-case doctrine
applies in the social security context. Because the evaluation
of Dr. Drazkowski’s and LPC Galler’s opinions was settled
in the district court’s first decision and was not part of the
additional proceedings on remand, the panel affirmed the

district court’s refusal to revisit its evaluation post-remand
based on the law-of-the-case doctrine.
The panel explained that a social-security applicant who
is granted a partial remand by the district court has two
options to preserve her right to appeal that decision: (1) she
may immediately appeal the remand order, but she must
raise all available issues to avoid forfeiting further review;
or (2) she may proceed on remand, understanding that the
district court may later decline to revisit previously settled
issues that were not the subject of the remand based on the
law-of-the-case doctrine. That choice will not foreclose
later review by this court of any district court determination,
whether made before or after the remand.
The panel addressed other issues in a concurrently filed
memorandum disposition.

4 FALLON V. DUDEK
OPINION
FORREST, Circuit Judge:
Mya Noelia Fallon appeals the denial of her application
for Supplemental Security Income (SSI) under the Social
Security Act, arguing in part that the district court
misapplied the law-of-the-case doctrine by refusing to
reconsider some of the medical evidence following its initial
remand to the agency for further proceedings. 1 Specifically,
Fallon contends that law of the case does not apply because
under the Social Security Act the district court’s two
decisions (before and after remand) were not issued in the
same “case.” Fallon misunderstands the law. We have
previously held that the law-of-the-case doctrine applies in
social-security cases. Stacy v. Colvin, 825 F.3d 563, 567 (9th
Cir. 2016). Given the arguments advanced by Fallon, we
take this opportunity to further explain the application of law
of the case in this context.
BACKGROUND
Fallon suffered from epileptic seizures throughout her
childhood. When she was fifteen, doctors performed an
anterior temporal lobectomy and removed her inferior
frontal cortex, which significantly reduced the frequency of
her seizures. Although Fallon’s application for SSI is based
in part on her seizures, it also focuses on—and this appeal
revolves around—her ongoing cognitive and behavioral
limitations.
1
Fallon also appeals the district court’s conclusions that substantial
evidence supported the Administrative Law Judge’s assessment of other
medical and lay witnesses and its Step-Five findings. We address these
issues in a concurrently filed memorandum disposition.
FALLON V. DUDEK 5
As part of Fallon’s application, her neurologist, Dr.
Joseph Drazkowski, assessed moderate-to-severe limitations
in her cognitive functioning. He also found her physically
limited. Licensed professional counselor (LPC) Terry Galler
discussed Fallon’s post-traumatic stress disorder and
generalized anxiety disorder diagnoses, which contribute to
her “significant cognitive and developmental impairments”
and underdeveloped social skills. Fallon’s application was
also supported by other medical professionals, her family,
and her own testimony.
An Administrative Law Judge (ALJ) found Fallon not
disabled under the standard five-step evaluation. See 20
C.F.R. § 416.920. As relevant to this opinion, the ALJ
assigned minimal weight to LPC Galler’s opinion and parts
of Dr. Drazkowski’s opinion, and no weight to
Dr. Drazkowski’s opinion about Fallon’s residual functional
capacity. The ALJ also discredited other medical and lay
testimony to various degrees.
Fallon appealed, and the district court reversed in part
and remanded. The district court found that the ALJ properly
discounted Dr. Drazkowski’s and LPC Galler’s opinions.
But it concluded that the ALJ erred in discounting the
remaining witnesses and remanded for further consideration
of the record. Fallon appealed to this court only the remedy
ordered by the district court on remand, arguing that the
remand should have been for an award of benefits rather than
for further proceedings. We affirmed, and the case was
remanded to the agency. See Fallon v. Kijakazi, No. 20-
16884, 2021 WL 5906143 (9th Cir. Dec. 14, 2021)
(unpublished).
On remand, an ALJ again found Fallon not disabled. The
ALJ conducted the inquiries mandated by the district court’s
6 FALLON V. DUDEK
order and incorporated by reference the prior ALJ’s
undisturbed evaluations, including of Dr. Drazkowski’s and
LPC Galler’s opinions. Fallon again appealed, and this time
the district court affirmed. While the district court
scrutinized the ALJ’s new findings, it refused, under the law-
of-the-case doctrine, to revisit its prior conclusions about
Dr. Drazkowski’s and LPC Galler’s opinions. Fallon
appealed, arguing the district court’s refusal to reconsider
this medical evidence was error. We have jurisdiction under
28 U.S.C. § 1291.
DISCUSSION
We review a district court’s decision to apply law of the
case for abuse of discretion. See Stacy v. Colvin, 825 F.3d
563, 567 (9th Cir. 2016). Because 42 U.S.C. § 405(g)
“directs the entry of a final, appealable judgment even
though that judgment may be accompanied by a remand
order,” Sullivan v. Finkelstein, 496 U.S. 617, 629 (1990),
Fallon contends that the law-of-the-case doctrine does not
apply. In her view, this is true because the district court’s
post-remand decision affirming the ALJ was not rendered in
the same “case” as its earlier decision remanding for further
administrative proceedings. This is contrary to our precedent
establishing that “the law of the case doctrine . . . appl[ies]
in the social security context.” Stacy, 825 F.3d at 567. And
rightfully so. That doctrine “promotes the finality and
efficiency of the judicial process by protecting against the
agitation of settled issues.” Christianson v. Colt Indus. Op.
Corp., 486 U.S. 800, 816 (1988) (internal quotation
omitted). Those values are equally promoted in social-
security cases, notwithstanding formalistic notions of
whether the same “case” returns to the district court
following remand. Accordingly, the district court did not
FALLON V. DUDEK 7
abuse its discretion by declining to revisit its evaluation of
Dr. Drazkowski’s and LPC Galler’s opinions.
But that is not the end of the matter. Fallon worries that
our approval of the district court’s approach will create
inefficiencies, forcing social-security applicants to
immediately appeal partial remands to preserve appellate
review of any unfavorable aspects of such decisions. Cf.
Forney v. Apfel, 524 U.S. 266, 267 (1998) (allowing social-
security applicants to appeal a district court’s remand order).
This concern is unwarranted. “The law of the case doctrine
generally prohibits a court from considering an issue that has
already been decided by that same court or a higher court in
the same case.” Stacy, 825 F.3d at 567 (emphasis added). A
social-security applicant who prefers to proceed on remand
rather than immediately appealing a decision she does not
agree with may do so, and if there is a subsequent appeal
following remand, the district court may appropriately
decline to revisit its undisturbed pre-remand holdings. But
when the case reaches this court, we are not bound by the
law of the case if the case has not previously been before us. 2
In this context, we may review all the district court’s
holdings, whether from before or after the remand.
Of course, here Fallon did immediately appeal the
district court’s remand order, but contested only the district
court’s decision to remand for further proceedings rather
than for an award of benefits. In that first appeal, she also
2
To the extent our unpublished disposition in Hammond v. Berryhill,
688 F. App’x 486, 488 (9th Cir. 2017), creates confusion by suggesting
that the failure to appeal a district court’s partial remand gives that
decision “preclusive effect under law of the case,” that understanding is
only partially accurate. In this context, preclusive effect applies to the
district court, but not to this court.
8 FALLON V. DUDEK
could have challenged the district court’s evaluation of
Dr. Drazkowski’s and LPC Galler’s opinions. By not doing
so, she forfeited her ability to raise those arguments in this
second appeal to this court. See Kesselring v. F/T Arctic
Hero, 95 F.3d 23, 24 (9th Cir. 1996) (per curiam) (“Since
[the] appellant failed to raise [an] issue in its first appeal, it
is waived.”). Thus, Fallon’s inability to challenge the district
court’s evaluation of Dr. Drazkowski’s and LPC Galler’s
opinions is not due to the law-of-the-case doctrine, but her
failure to raise that issue in this court at her first opportunity
to do so.
CONCLUSION
In sum, a social-security applicant who is granted a
partial remand by the district court has two options to
preserve her right to appeal that decision. She may
immediately appeal the remand order, Forney, 524 U.S at
267, but she must raise all available issues to avoid forfeiting
further review, Kesselring, 95 F.3d at 24. Alternatively, she
may proceed on remand, understanding that the district court
may later decline to revisit previously settled issues that
were not the subject of the remand based on the law-of-the-
case doctrine. Stacy, 825 F.3d at 567. That choice will not
foreclose later review by this court of any district court
determination, whether made before or after the remand.
Because the evaluation of Dr. Drazkowski’s and LPC
Galler’s opinions was settled in the district court’s first
decision and was not part of the additional proceedings on
remand, the district court’s refusal to revisit its evaluation
post-remand based on the law-of-the-case doctrine is
AFFIRMED.
