Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS WESTERN DIVISION

Jacki D., Plaintiff, Case No. 3:25-cv-50039 v. Honorable Michael F. Iasparro Frank J. Bisignano, Commissioner of Social Security,

Defendant.

MEMORANDUM OPINION AND ORDER Plaintiff Jacki D. brings this action under 42 U.S.C. § 405(g) seeking reversal of the decision denying her applications for disability insurance benefits and supplemental security income.1 For the reasons set forth below, the Commissioner’s decision is reversed, and this case is remanded. BACKGROUND Plaintiff filed applications for disability insurance benefits and supplemental security income alleging a disability onset date of January 1, 2021. R. 201, 208. Following a hearing, an Administrative Law Judge (“ALJ”) issued an unfavorable decision on May 22, 2024, finding that Plaintiff is not disabled. R. 15-30. The ALJ concluded that Plaintiff had the residual functional capacity (“RFC”) to perform medium work with the following limitations: The claimant can frequently reach overhead to the left, and she can frequently reach for all other reaching. The claimant can frequently climb ramps and stairs, and occasionally climb ladders, ropes, and scaffolds. The claimant can occ [sic] stoop, kneel, crouch, and crawl. The claimant can occasionally work at unprotected heights, work occasionally in extreme cold, and work occasionally in extreme heat. R. 22. The ALJ found that Plaintiff could perform past relevant work and that there are other jobs that Plaintiff can perform that exist in significant numbers in the national economy. R. 28. The Appeals Council denied Plaintiff’s request for review on November 20, 2024, making the ALJ’s decision the final decision of the Commissioner. R. 1-6; 20 C.F.R. § 404.900(a)(5). Plaintiff then filed this action seeking judicial review. Dkt. 1.

1 The parties have consented to the jurisdiction of a United States Magistrate Judge for all proceedings pursuant to 28 U.S.C. § 636(c). See Dkt. 8. STANDARD OF REVIEW A reviewing court may enter judgment “affirming, modifying, or reversing the decision of the [Commissioner], with or without remanding the cause for a rehearing.” 42 U.S.C. § 405(g). If supported by substantial evidence, the Commissioner’s factual findings are conclusive. Id. The court’s review of the Commissioner’s findings is subject to “a very deferential standard.” Thorlton v. King, 127 F.4th 1078, 1081 (7th Cir. 2025). When reviewing the ALJ’s decision, the court’s inquiry is limited to determining whether the ALJ’s decision is supported by substantial evidence or resulted from an error of law. Mandrell v. Kijakazi, 25 F.4th 514, 515 (7th Cir. 2022). Substantial evidence is “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Biestek v. Berryhill, 587 U.S. 97, 103 (2019). “The threshold for substantial evidence ‘is not high.’” Warnell v. O’Malley, 97 F.4th 1050, 1052 (7th Cir. 2024) (quoting Biestek, 587 U.S. at 103). The substantial evidence standard is satisfied when the ALJ provides “an explanation for how the evidence leads to their conclusions that is sufficient to allow us, as a reviewing court, to assess the validity of the agency’s ultimate findings and afford [the appellant] meaningful judicial review.” Warnell, 97 F.4th at 1054 (internal quotation marks and citation omitted). To determine whether substantial evidence exists, the court reviews the record as a whole but “will not reweigh the evidence, resolve debatable evidentiary conflicts, determine credibility, or substitute [its] judgment for the ALJ’s determination so long as substantial evidence supports it.” Id. at 1052–53; Beardsley v. Colvin, 758 F.3d 834, 836 (7th Cir. 2014). Thus, “we will reverse an ALJ’s decision only if the record compels a contrary result.” Thorlton, 127 F.4th at 1081 (citation modified). DISCUSSION Plaintiff challenges the Commissioner’s decision on five grounds: (1) Plaintiff’s past relevant work is too remote; (2) the ALJ relied on unreliable vocational expert testimony to find significant jobs in the national economy; (3) the ALJ did not provide substantial evidence for her evaluation of the state agency medical consultants’ opinions; (4) the ALJ’s RFC determination lacked sufficient support; and (5) the ALJ improperly evaluated Plaintiff’s subjective symptoms. Dkt. 17. The Commissioner asserts that Plaintiff’s arguments largely ask for the Court to reweigh the evidence. Dkt. 22, at 12. However, as Plaintiff succinctly explained in her reply, she “does not ask this court to re-weigh the evidence but rather [argues] that the ALJ did not weigh the evidence in the first place.” Dkt. 25, at 15. After reviewing the ALJ’s decision “holistically,” the Court agrees that the ALJ’s analysis is insufficient to “build a ‘logical bridge’ from the evidence to her conclusion” as is required. Chrisman on behalf of N.R.C. v. Bisignano, 137 F.4th 618, 624 (7th Cir. 2025) (quoting Warnell, 97 F.4th at 1054). 1) RFC Determination A claimant’s RFC is “the most physical and mental work the claimant can do on a sustained basis despite her limitations.” Swiecichowski v. Dudek, 133 F.4th 751, 755 (7th Cir. 2025) (quoting Mandrell, 25 F.4th at 516). When determining a claimant’s RFC, regulations require that the ALJ consider seven strength functions – lifting, carrying, sitting, standing, walking, pushing, and pulling – and “describe ‘how the evidence supports each conclusion’” with citations to the record. Jarnutowski v. Kijakazi, 48 F.4th 769, 773-74 (7th Cir. 2022) (quoting SSR 96-8p: Assessing RFC in Initial Claims, 61 Fed. Reg. 34474, 34478 (July 2, 1996)). A failure to do so “is a sufficient basis, by itself, for [the Court] to reverse an ALJ’s decision.” Id. at 774. Here, the ALJ failed to comply with this regulation. Although several of these strength functions were mentioned in the ALJ’s summary of the record, the ALJ made no specific findings about any of them. While ALJs are not always required to discuss a function area when no limitation of that function has been alleged or is otherwise indicated in the record, this exception does not apply here because Plaintiff has alleged that she has some level of limitation in each of the seven functions. See Jeske v. Saul, 955 F.3d 583, 596 (7th Cir. 2020) (“[I]f the claimant has not alleged [] a limitation and the record lacks information indicating that one exists . . . we may conclude that the ALJ found no limitation in that function, without the ALJ stating so explicitly.”). In fact, the ALJ recognized that Plaintiff “testified that she had significant limitations in sitting, standing, walking, and lifting.” R. 26. Yet, the ALJ did not articulate her findings for any of the seven strength functions nor save this inadequacy with a “discussion show[ing] that the ALJ considered all strength-demand function limitations.” Jeske, 955 F.3d at 596. Of particular importance is the ALJ’s lack of discussion about lifting and carrying as “that [is] the primary and relevant difference between light work and medium work” and the ALJ, contrary to all medical opinions in the record, found Plaintiff capable of medium work. Jarnutowski, 48 F.4th at 774-75 (remanding where the ALJ provided no explanation for her conclusion that the claimant could perform the physical requirements of medium work).
