Patino: An Uncertain Injury Date Required Further Review of the Record

If you remember being hurt at work but cannot remember the exact day, a date on a claim form can take on more importance than you expected. In Patino v. Salinas Farm Labor Contractor, Inc., No. ADJ20388475 (WCAB Oct. 19, 2026), the trial judge found the worker credible but rejected her proposed change of injury date. The Appeals Board granted reconsideration for further study of the evidence and legal issues. Its order deferred the final decision; the worker’s request to change the date and the merits of her claim remained unresolved.

The agreed date became a barrier when the employment records did not match

At the June 22, 2026 mandatory settlement conference, the parties agreed that Maria Lorena Patino would maintain June 6, 2024 as the injury date at trial. The agreement appeared in the pretrial conference statement. Just before the July 27 trial, an amended application sought May 31 instead, referring to payroll records. The history begins in Patino and continues onto the next page.

The judge found no employment on June 6 and held the amended application invalid. The findings also treated the employment issue as eliminating the need for further qualified medical evaluator reporting. Patino sought relief from the date stipulation, amendment to conform to the proof, and further proceedings. Changing a pleading and obtaining relief from an express trial stipulation were both part of the dispute.

The last day worked did not resolve when the injury happened

Patino struggled to remember both the injury date and her last workday. The judge nevertheless described her as a credible witness who answered directly. She testified that she returned the day after the injury and later described working four additional days. The judge’s account of that testimony appears in Patino.

Payroll and timecard records identified May 31 as the last day worked and showed no later employment. The judge reasoned that May 31 also conflicted with the testimony about returning to work after the injury. The dispute therefore involved more than replacing an unsupported June date with a date appearing in payroll. It required accounting for the sequence of injury and subsequent work. The Report’s explanation starts in Patino and continues onto the next page.

The amended application’s electronic signature was also questioned during testimony. The judge expressly said that this issue was included for completeness and formed no part of the decision. It should not be substituted for the judge’s actual explanation about the stipulated date, evidence and timing of the amendment.

A pleading amendment and a binding stipulation raise different questions

The judge’s Report relied on Robinson v. Workers’ Compensation Appeals Board, 194 Cal.App.3d 784, 790–791 (1987), concerning stipulations and relief for good cause. The Report addressed mistake, inadvertence, excusable neglect and other circumstances, while distinguishing an excusable mistake from a failure to investigate available facts. Its discussion begins in Patino and continues on the next page. The judge concluded that good cause had not been shown and that the proposed date still failed to reconcile the testimony and employment records.

The Board highlighted a different set of principles for its further review. Rule 10517 permits amendment of pleadings to conform to proof. Its en banc decision in Perez v. Chicago Dogs, 90 Cal.Comp.Cases 830, 836–837 (2025), addresses liberal construction, a fair hearing and a decision on the merits. The Board also identified the need for admitted evidence and further development when the record is insufficient. That discussion begins in Patino and continues through the next two pages.

These principles explain the inquiry, rather than decide it. The Board said its preliminary review indicated that the evidence and stipulations might require further development concerning the injury date and surrounding circumstances. It granted reconsideration so it could study the complete record and reach a reasoned decision. The explanation appears in Patino.

The order kept the dispute open for a final decision

The operative order granted the petition and deferred the final decision after reconsideration. Read the actual order in Patino. A grant at this stage is a procedural step toward further review, rather than an award of benefits or a final acceptance of May 31 as the injury date. That limit matters to a worker deciding what has actually changed.

For another disputed date, the useful comparison is among the event history, work after the injury, original forms and the exact agreement made for trial. Identify why a date was used, what reliable evidence contradicts it and how the requested correction would affect the other parties’ ability to respond. Our guide to an injury date that conflicts with payroll develops that preparation task without asking a worker to fill a memory gap with a guess.
