In California, if the workers' comp judge mishears testimony or makes factual findings the record does not support, the worker can file a Petition for Reconsideration under §5903 within 25 days of mail service (20 electronic) — the §5903(3) ground that "the evidence does not justify the findings." Yazdchi Law, a Certified Specialist in Workers' Compensation Law firm, handles these.
For an injured California worker who has just received an adverse Findings and Award from a workers' compensation judge, the most distressing scenario is reading the decision and realizing the judge got the facts wrong. The judge wrote that the worker's testimony was inconsistent when it was not; the judge attributed statements to the worker that the worker never made; the judge described the injury mechanism incorrectly; the judge said the QME testified to a finding that the QME never made. The factual mistake feels devastating — but California workers' compensation law has a specific remedy for it, and the deadline to invoke that remedy is short.
This guide walks through the §5903(3) "evidence does not justify the findings" reconsideration ground under California Labor Code §5903: what the ground actually says, what kinds of factual errors it reaches, how to invoke it in a Petition for Reconsideration, and what the §5900 WCAB review process looks like. It is written for a worker who has just received an adverse Findings and Award containing factual errors and needs to act fast.
The short version: under §5903, a Petition for Reconsideration is the worker's primary remedy when the workers' compensation judge has made factual findings the record does not support. The deadline is 25 days from service by mail (or 20 days from electronic service). The §5903(3) ground — "that the evidence does not justify the findings of fact" — is the specific basis for challenging factual mistakes. The §5900 WCAB review process examines the record and can modify, reverse, or remand the decision. The remedy is available, but only if the deadline is met.
Under California Labor Code §5903, a Petition for Reconsideration may be filed within 25 days of service of the Findings and Award by mail (or 20 days from electronic service). The grounds for reconsideration are statutorily limited to five categories: (1) the WCAB acted without or in excess of its powers; (2) the order, decision, or award was procured by fraud; (3) the evidence does not justify the findings of fact; (4) the petitioner has discovered new evidence material to the petitioner's case, which could not, with reasonable diligence, have been discovered and produced at the hearing; and (5) the findings of fact do not support the order, decision, or award.
The §5903(3) ground — "the evidence does not justify the findings of fact" — is the specific basis for challenging factual mistakes by the workers' compensation judge. It reaches situations where the judge wrote findings that the trial record does not support, where the judge attributed testimony to a witness that the witness did not give, where the judge summarized the medical-legal evidence in ways the actual reports do not bear out, and where the judge made factual conclusions that no reasonable trier of fact could draw from the record.
California Petitions for Reconsideration under §5903(3) commonly identify several patterns of factual error. First, mistaken summaries of the worker's testimony — the judge wrote that the worker testified to facts the worker never stated, or attributed statements the worker actually denied. Second, mistaken summaries of medical-legal evidence — the judge wrote that the QME under California Labor Code §4062.2 concluded X when the QME report actually concluded Y. Third, mistaken summaries of documentary evidence — the judge wrote that a particular exhibit said one thing when it actually said another. Fourth, factual conclusions that no reasonable trier of fact could draw from the actual record — for example, finding that an injury was not work-related when the only medical evidence in the record affirmatively connected it to work.
The §5903(3) ground is not a re-trial. The WCAB reviews the existing record to determine whether the evidence supports the findings made. If the evidence does not support the findings, the Board can modify the findings, reverse the decision, or remand for further proceedings. If the evidence supports the findings — even barely — the Board will generally affirm.
Under §5903, the Petition for Reconsideration must be filed within 25 days from the date the Findings and Award was served by mail, or 20 days from the date of service if the document was served electronically. The deadlines are jurisdictional — a late Petition is generally barred regardless of the strength of the underlying grounds. The 25/20 day deadline runs from service date, not from receipt date; a worker who received the Findings and Award on day 20 because of mail delays does not get extra time.
The deadline drives the strategic posture. A worker who receives an adverse Findings and Award has to act quickly. The Petition itself must include the specific grounds, the specific evidence the petitioner relies on, and the specific relief sought. Many California reconsideration practitioners draft the Petition under 25/20 day pressure — sometimes only a few business days. A specialist attorney handles the deadline routinely, but the worker should engage representation immediately on receipt of any adverse Findings and Award.
Under California Labor Code §5900, the WCAB reviews the Petition for Reconsideration on the existing trial record. The Board typically issues an order granting or denying reconsideration within 60 days of the Petition's filing. If reconsideration is granted, the Board may modify the decision, issue a new decision, or remand the case to the trial judge for further proceedings. If reconsideration is denied, the worker's next remedy is a Writ of Review with the California Court of Appeal under California Labor Code §5950 within 45 days of the WCAB's denial.
The §5900 review is record-based — the Board does not take new evidence (with the narrow exception of newly-discovered material evidence under §5903(4)). The Board examines the trial transcripts, the medical-legal reports, the exhibits, and the trial judge's Findings and Award against the §5903 grounds asserted in the Petition. Effective §5903(3) Petitions cite the specific evidence and identify exactly where the trial judge's findings diverge from the record.
A strong §5903(3) Petition for Reconsideration has several elements. First, a precise identification of each finding the petitioner challenges. Second, citations to the specific evidence — trial transcript pages, exhibit numbers, medical-legal report pages — that the petitioner argues does not support the finding. Third, a clear statement of what the actual evidence shows, with comparison to what the trial judge wrote. Fourth, the specific relief sought — modification of the finding, reversal of the decision, or remand for further proceedings. The Petition is generally accompanied by a Points and Authorities brief setting out the legal standard and the supporting case law.
An adverse §5900 reconsideration decision is reviewable by the California Court of Appeal through a Writ of Review under California Labor Code §5950, filed within 45 days. The Writ of Review is a discretionary remedy — the Court of Appeal does not have to grant review. When granted, the Court of Appeal reviews the WCAB's decision on the record. If the Writ is denied, the case generally becomes final and the workers' comp remedies are exhausted on that issue. Workers with serious factual concerns should weigh both the §5903 Petition and the §5950 Writ as part of an integrated post-trial strategy.
California Labor Code §132a prohibits retaliation. California Labor Code §3351 extends coverage regardless of immigration status. California Labor Code §244 prohibits immigration-status threats. California Labor Code §5811 provides a qualified interpreter at any WCAB hearings, with the cost charged to the defendant. Medical care under California Labor Code §4600 continues during reconsideration. Unreasonable delay can support a 25% penalty under California Labor Code §5814.

Tap to call →The §5903(3) "evidence does not justify the findings" reconsideration ground is the California worker's remedy when the workers' compensation judge has gotten the facts wrong. The 25/20 day deadline is hard, the Petition has to engage the specific record evidence, and the §5900 WCAB review is record-based. But the remedy is real — many factual errors at trial are reversed or modified on reconsideration.
The §5903 deadline is jurisdictional. A late Petition is generally barred. The 25/20 days runs from service, not from receipt. Workers receiving any adverse Findings and Award should engage a specialist attorney immediately — the Petition must include grounds, evidence citations, and legal authority, and there is no second deadline.
A strong §5903(3) Petition cites trial transcript pages, exhibit numbers, and medical-legal report pages showing where the trial judge's findings diverge from the actual record. Generic "the judge was wrong" Petitions rarely succeed; record-citation-grounded Petitions often do. The QME or AME report under California Labor Code §4062.2 is often a central document — petitioners cite the specific pages of the medical-legal report against the judge's summary of it.
