Substantial-Evidence Deference in SSA Cases: Generalized, Uncited Appellate Challenges and Post-Decision Evidence Do Not Justify Remand

1. Introduction

Tarver v. Bisignano (5th Cir. July 21, 2026) is a nonprecedential Summary Calendar decision in which pro se claimant Andrew Tarver appealed the denial of Social Security disability benefits. Tarver alleged disabling limitations from Crohn’s disease, colitis, and anemia—especially extreme fatigue and frequent restroom use. The Commissioner (through an ALJ) concluded Tarver was not disabled at step five of the sequential evaluation, relying on a sedentary residual functional capacity (RFC) that included “ready access to a restroom for not more than 10% of the workday” and vocational-expert testimony identifying jobs existing in significant numbers.

On appeal, Tarver presented three broad arguments: the decision failed to reflect real-world limitations, the Commissioner did not consider a treating physician’s opinion, and the RFC ignored fatigue, bowel frequency, and pain. The Fifth Circuit affirmed, emphasizing (i) the strict nature of substantial-evidence review and (ii) the practical consequences of presenting generalized arguments without record and legal citations.

2. Summary of the Opinion

The Fifth Circuit affirmed the denial of benefits because substantial evidence supported the ALJ’s findings and Tarver’s appellate briefing was too undeveloped to justify reversal or remand. The court held:

  • Under substantial-evidence review, the court cannot reweigh evidence or substitute its judgment for the Commissioner’s.
  • Tarver did not show a “conspicuous absence of credible choices” or uniform medical contradiction of the ALJ’s determination.
  • The record contained supporting evidence, including unanimous medical opinions that Tarver was not disabled and an RFC restroom-time limitation consistent with Tarver’s own testimony.
  • A treating physician’s opinion issued after the ALJ decision, addressing temporary disability in July–August 2024, was outside the relevant period; and in any event a month-long disability does not satisfy the statutory 12-month duration requirement.

3. Analysis

A. Precedents Cited

The panel’s reasoning is largely structured around settled Fifth Circuit standards governing appellate briefing and substantial-evidence review.

1) Briefing adequacy and the need for citations

  • Rollins v. Home Depot USA, 8 F.4th 393, 397 & n.1 (5th Cir. 2021): The court cited Rollins alongside Federal Rule of Appellate Procedure 28(a)(8)(A) to underscore that an appellant must supply contentions, reasons, and supporting citations to authority and the record. The Tarver panel used this principle to explain why “thin” and generalized arguments—nine sentences with no citations—do not meaningfully engage the standard of review and therefore cannot support appellate relief.

2) The substantial-evidence framework and limits on appellate reweighing

  • Masterson v. Barnhart, 309 F.3d 267, 272 (5th Cir. 2002): Masterson supplies two core rules the panel applied: (i) the court affirms if the Commissioner’s findings are supported by substantial evidence; and (ii) the court will not “re-weigh the evidence, try the questions de novo, or substitute our judgment.” Tarver’s arguments would have required the court to reassess symptom severity and competing evidence—exactly what Masterson forbids.
  • Taylor v. Astrue, 706 F.3d 600, 602 (5 th Cir. 2012) (per curiam): Taylor provides the definition of substantial evidence as “more than a scintilla” but not necessarily a preponderance. The panel invoked this to highlight the low-to-moderate evidentiary threshold the Commissioner must meet, reinforcing that a claimant must do more than point to contrary inferences.

3) When “no substantial evidence” exists

  • Hames v. Heckler, 7 07 F.2d 162, 164 (5th Cir. 1983) (per curiam): Quoted for the proposition that “no substantial evidence will be found only where there is a conspicuous absence of credible choices or no contrary medical evidence.” The panel used Hames to set the high bar Tarver needed to clear—and failed to—because the record contained medical opinions and testimonial support for the RFC.
  • Whitehead v. Colvin, 820 F.3d 776, 779 (5th Cir. 2016) (per curiam): Whitehead reinforced the “credible evidentiary choices” concept and supported the court’s conclusion that the record did not reflect an evidentiary vacuum. In Tarver, multiple medical reviewers found non-disability, which is precisely the kind of “choice” that forecloses a “no substantial evidence” argument.

B. Legal Reasoning

The opinion turns on an orthodox application of administrative-law deference in Social Security appeals:

  1. Standard of review dictates the outcome. The court framed the appeal as constrained by substantial-evidence review and repeatedly emphasized it could not revisit factfinding. This framing is decisive: Tarver’s core complaints (fatigue, bathroom frequency, pain) are fact-intensive and, on this record, could only prevail if the ALJ’s view lacked substantial support.
  2. The claimant’s briefing did not engage the standard. By noting the absence of record and legal citations (Fed. R. App. P. 28(a)(8)(A); Rollins v. Home Depot USA), the panel signaled that appellate courts are not obligated to construct arguments on a litigant’s behalf, even for pro se appellants. The deficiency mattered because it left the court without developed grounds to identify reversible error under the governing standard.
  3. Evidence supporting the RFC was identified and deemed sufficient. The court highlighted two concrete supports for the ALJ’s restroom limitation: (i) Tarver’s own testimony that he needed bathroom access “once an hour for three to five minutes each time,” and (ii) the medical opinion evidence (Drs. Martorella, Hall-Hoskins, and Ligon) uniformly concluding Tarver was not disabled. With that evidentiary foundation, the panel held it could not find the “conspicuous absence of credible choices” required by Hames.
  4. Post-decision treating opinion and duration rules. The panel accepted the Appeals Council’s relevance rationale: the treating physician’s opinion covered July–August 2024, after the ALJ’s June 12, 2024 decision. The court added an independent legal point: even if credited, a single month of disability does not satisfy the statutory definition requiring a continuous period of “not less than 12 months.” See 42 U.S.C. § 423(d)(1)(A).

C. Impact

Although designated nonprecedential (5th Cir. R. 47.5), the decision is instructive in three practical ways:

  • SSA appeals live or die by the standard of review. Tarver illustrates how difficult it is to overturn an ALJ on substantial-evidence review absent targeted challenges to specific findings, evidentiary gaps, or legal errors (e.g., misapplication of regulations).
  • Appellate briefing discipline matters, even for pro se litigants. By foregrounding Rule 28(a)(8)(A) and Rollins, the opinion reinforces that generalized disagreement with the ALJ is insufficient; appellants must tie arguments to the record and to legal standards.
  • Temporal relevance and the 12-month duration requirement limit late-submitted evidence. The decision underscores two common barriers: evidence outside the adjudicated period may be rejected as irrelevant, and temporary limitations—no matter how severe— often cannot establish “disability” unless they meet the statutory duration requirement.

4. Complex Concepts Simplified

  • Residual Functional Capacity (RFC): The most a claimant can still do despite limitations. The ALJ used an RFC for sedentary work with additional restrictions, including limiting restroom time to no more than 10% of the workday. (See 20 C.F.R. § 416.945(a)(1).)
  • Sequential evaluation / “step 5”: A five-step process for deciding disability. At step five, the burden shifts to the Commissioner to show other jobs exist in significant numbers that the claimant can perform given the RFC. (See 20 C.F.R. § 416.920(a)(4)(i)-(v).)
  • Substantial evidence: More than a tiny amount of evidence (“a scintilla”), but not necessarily the stronger side of the evidence. If reasonable evidence supports the ALJ, the court must affirm even if it might have decided differently.
  • Vocational expert (VE) hypotheticals: The ALJ asks a VE whether jobs exist for a person with specified limitations. Here, the VE identified jobs if restroom time was ≤10% of the day, but none if restroom time was ≥15%, making the precise RFC finding critical.
  • 12-month duration requirement: Federal law requires an impairment to last (or be expected to last) continuously for at least 12 months to qualify as a “disability.” A one-month period of disability, standing alone, does not meet the definition. (42 U.S.C. § 423(d)(1)(A).)

5. Conclusion

Tarver v. Bisignano reaffirms the Fifth Circuit’s strict application of substantial-evidence review in Social Security cases and demonstrates how underdeveloped appellate arguments—especially those lacking record and authority citations—rarely succeed. The panel’s affirmance rests on two anchors: (1) the appellate court’s inability to reweigh symptom evidence and (2) the presence of “credible choices” supporting the ALJ’s RFC, including medical opinions and testimony consistent with the restroom-time limitation. The decision also highlights that post-decision, short-term treating opinions typically cannot establish disability, both because of temporal relevance and the statutory 12-month duration requirement.
