Decision: Rivera v. Sodexo, Inc., No. ADJ10837798 (WCAB Aug. 31, 2026).

Both sides needed a better evidentiary record in Rivera v. Sodexo, Inc., No. ADJ10837798 (WCAB Aug. 31, 2026). The worker challenged a 38-percent permanent-disability award based on an old examination and disputed rating methods. The employer challenged rejection of diabetes-related apportionment. Despite counsel’s missed opportunity to arrange updated reporting, the panel rescinded the award and returned all outstanding issues for further medical and vocational development. It resolved neither party’s requested disability result. The WCAB panel’s reasoning addresses why the stale medical and vocational record required further development. Rivera, slip opinion, pages 1–2, 5–6.

The core examination no longer reflected the current record

The worker was a housekeeper with an accepted cervical and lumbar cumulative injury ending April 24, 2017. Orthopedic agreed medical evaluator Dr. Peter Mandell examined her on April 11, 2018. That remained his only examination, although he supplied supplements and deposition testimony through late 2021. Later neurologist and internist evaluations did not find industrial injury; the file also acquired a functional-capacity evaluation and vocational reports. The final internist supplement was dated May 29, 2025. The issue was whether the orthopedic and vocational opinions still addressed the worker’s present condition and the questions being tried—not simply whether a report carried an old date. Rivera, pages 1, 3–4.

The parties disputed different parts of the rating. Dr. Mandell recommended adding the cervical and lumbar disability rather than combining it through the Combined Values Chart. The judge instead combined them. The judge accepted apportionment to earlier injuries but found the proposed allocation to nonindustrial diabetes inadequate. The worker challenged the 38-percent result and incomplete development; the defendant sought the diabetes allocation. An updated record could therefore affect either side’s position. Rivera, pages 1–2.

Intervening law changed the questions

Since the AME and vocational experts last reported, the Board had issued the en banc decisions Vigil v. County of Kern (2024) 89 Cal.Comp.Cases 686 and Nunes v. State of California (2023) 88 Cal.Comp.Cases 741. The panel identified them as potentially relevant to the reporting in this case. The live questions included the AME’s proposed addition of impairments, the vocational challenge to the scheduled rating and the disputed medical basis for diabetes apportionment. Further development gave the defendant an opportunity to address that last deficiency too. Rivera, pages 1, 5.

The decision required the evidence to address those questions before another merits decision. It did not select addition over combination, approve the diabetes allocation or find that vocational evidence established total disability. For comparison, our Valencia analysis concerns a developed medical-and-vocational record the panel found sufficient; Rivera concerns the need to complete the proof first.

Counsel’s delay did not cure an inadequate record

The chronology explained the trial judge’s frustration. At a November 10, 2025 hearing, the case went off calendar with a direction to contact Dr. Mandell by January 5, 2026. After counsel apparently failed to do so, the defendant filed another declaration of readiness on January 7. The worker did not object to that filing. At the February settlement conference, the judge closed discovery for lack of diligence in scheduling a re-examination. At the April 8 trial, the worker again requested development and explained that her vocational expert had retired. Rivera, page 4.

The panel criticized that delay but separated misconduct from the quality of the evidence needed to decide disability. Incomplete, stale or no-longer-relevant medical evidence could not become substantial evidence because counsel had handled discovery poorly. The judge could address bad-faith or dilatory conduct through other remedies, including Labor Code section 5813. That separation supported one more opportunity for both parties to meet their respective proof burdens. Rivera, pages 4–5.

Substantial justice required remand

The operative order granted both petitions, rescinded the May 28, 2026 findings and award and returned the matter to the trial level for further proceedings and a decision on all outstanding issues. The panel expressly gave no view on their ultimate resolution. The applicant still bore the burden of proving permanent disability and rebutting the scheduled rating; the defendant still had to support its asserted apportionment. Rivera, pages 5–6.

For a similar record, identify what has changed since the examination and which question each existing report fails to answer. An evaluator addressing the present restrictions may need the later specialty reports and functional findings; a disputed addition or apportionment proposal needs its own medical explanation. Preserve the scheduling directions, requests and responses as well. They explain why discovery was closed and what relief is now sought, while the medical and vocational records explain why a merits decision may still require further evidence.

Key takeaways

• Update medical evidence when an old examination no longer addresses the current condition.
• Identify how the later Vigil and Nunes decisions may affect the medical and vocational reporting; the panel called for development before deciding the disputed rating and apportionment questions.
• Use procedural remedies for delay without deciding merits on an inadequate record.
• Distinguish an order developing the record from a final disability determination.
