What Happens at a California Workers' Comp Trial?

What happens during the trial itself?

A workers' compensation judge hears your case and decides it. There is no jury. The judge reviews the stipulations and issues from your pretrial conference statement, looks at the exhibits, listens to testimony, then issues a written Findings and Award.

A trial in California workers' comp is less like a television courtroom and more like a focused hearing in front of one judge. Both sides already exchanged their medical reports and other proof before the trial date arrived. The judge's job at trial is to decide only the specific points the two sides still disagree about.

California law calls this judge a workers' compensation judge, often shortened to WCJ. The WCJ works through the Workers' Compensation Appeals Board, or WCAB, the state agency that resolves these disputes. No jury is ever part of the process.

This page walks through each stage of a trial: how a case reaches trial, what stipulations and issues mean, and what the judge looks at. It also covers how to prepare to testify and how soon a decision usually arrives.

How does a workers' comp case get set for trial?

A case usually reaches trial only after a Mandatory Settlement Conference fails to resolve it, and the judge sets the disputed issues for trial.

Most cases move toward trial after either side files a declaration of readiness to proceed. Labor Code section 5502 then requires a Mandatory Settlement Conference, generally 10 to 30 days later. At that conference, a workers' compensation judge or a settlement conference referee tries to resolve the dispute. If no deal is reached, the law directs the judge to frame the stipulations and issues for trial.

If the case still does not settle there, the law moves it toward trial. Labor Code section 5502 generally sets the trial within 75 days of the declaration of readiness to proceed. See our guide to the Mandatory Settlement Conference that comes before trial for a closer look at that earlier step. If you are still weighing both paths, our comparison of settling versus going to trial walks through the tradeoffs.

What are stipulations and issues at trial?

Stipulations are the facts both sides already agree on. Issues are the specific points still in dispute that the judge has to decide.

When a case does not settle at the Mandatory Settlement Conference, Labor Code section 5502 requires both sides to file a pretrial conference statement. That document lists the issues in dispute. Common examples are which body parts are covered, how much permanent disability you have, or whether your condition is work related. It also lists each side's proposed permanent disability rating, the exhibits each side plans to use, and the witnesses each side plans to call.

Discovery closes that same day, under the same statute. Evidence found after that date generally cannot be used at trial. The one exception is when the side offering it shows the evidence could not have been found earlier with reasonable effort. That is one reason it helps to gather your medical records and wage records well before that conference, not the week before trial.

Is a workers' comp hearing always a trial in California?

Not always. California workers' comp uses the word hearing broadly. A workers' comp hearing in California can be a short conference or the full trial where the judge takes evidence and decides the case.

You may see "hearing" used for a priority conference, a Mandatory Settlement Conference, a lien hearing, or the trial itself. The trial is the specific hearing where the judge takes testimony, admits exhibits, and resolves the issues listed in the pretrial conference statement. If a hearing notice does not make clear which type you have, ask your attorney or the district office clerk before the date arrives.

What exhibits and testimony does the judge consider?

The judge considers the exhibits named in the pretrial conference statement, often medical-legal reports, along with the testimony given at trial.

Reports from a Qualified Medical Evaluator, or QME, or an Agreed Medical Evaluator usually carry the most weight on medical questions such as disability or apportionment. Other common exhibits include wage records, treatment notes, and prior claim documents already marked and exchanged before trial.

You and any other listed witnesses may testify. Your own attorney asks questions first, and the defense attorney representing the insurance company gets to ask questions too. The judge may also ask questions directly. Labor Code section 5701 lets the Appeals Board or a judge dig further into a disputed question. For example, the judge can order more testimony or an inspection when needed.

If you are not comfortable testifying in English, you have the right to a qualified interpreter at no cost to you under Labor Code section 5811. Tell your attorney which language you need well before the trial date so one can be arranged.

How should I prepare to testify at my workers' comp trial?

Review your prior statements, bring identification and any papers your attorney requests, and answer each question honestly and only about what was actually asked.

Before trial, reread your deposition transcript and your medical reports so your testimony lines up with what is already in the record. Small, honest gaps in memory are normal, but a surprising new detail at trial can hurt your credibility with the judge.

At the hearing, listen to the whole question before you answer. Keep your answers short and factual. If you do not understand a question, say so and ask for it again instead of guessing. If you are not sure of an exact date or number, it is fine to say you are estimating.

Bring a photo ID and anything your attorney asks you to bring. Arrive with time to spare and dress the way you would for an important appointment. Your attorney can walk you through the specific issues at stake in your case before the trial date.

What is a Findings and Award, and how fast will the judge decide?

The judge rarely rules the same day. Once a case is submitted for decision, Labor Code section 5313 gives the judge 30 days to file written findings and an award, order, or decision.

A trial usually ends with the case "submitted," meaning the evidence is complete. That often happens the day testimony ends, though the judge may first allow short written closing statements from each side. Once the case is submitted, the 30-day clock in Labor Code section 5313 begins.

The result is a written decision, commonly called a Findings and Award. It states the judge's determination on each disputed issue. The law also requires a summary of the evidence and the reasons for the decision, served on both sides along with it. When no benefit is awarded on an issue, the same document is sometimes called a Findings and Order instead.

What if I disagree with the trial judge's decision?

You can ask the Workers' Compensation Appeals Board to reconsider. Labor Code section 5900 allows a petition, and Labor Code section 5903 sets a short deadline and limited grounds.

Either side can file a Petition for Reconsideration after a final Findings and Award. Labor Code section 5903 sets the deadline at 20 days after service of the decision. The exact date can shift depending on how the decision was served, so always check it against your proof of service. The petition also has to fit one of a short list of grounds, such as a legal error or findings the evidence does not support. The Appeals Board can also open its own review within 60 days of the decision under Labor Code section 5900.

According to the state Division of Workers' Compensation, that review goes to a seven-member Appeals Board. Because the deadline is short, save your decision and the proof of service the day it arrives. For the exact calculation and the full list of grounds, see our guide to the Labor Code 5903 reconsideration deadline and the Labor Code 5900 overview. If the judge already ruled against you, our guide on what to do if the judge rules against you walks through the options.
