What Is California Labor Code §5307: Rules of Practice and Procedure?

(a) The appeals board may, by an order signed by four members, do all of the following: (1) Adopt reasonable and proper rules of practice and procedure.

What does California Labor Code section 5307 cover?

Labor Code 5307 lets the appeals board write the procedural rules it follows in a workers' compensation case.

The Workers' Compensation Appeals Board, usually called the WCAB, is the state body that decides California workers' compensation disputes. Labor Code 5307 lets the WCAB adopt its own rules of practice and procedure. It must act through an order signed by at least four of its members. The same order can cover how minors and incompetent persons, meaning people who cannot manage their own affairs, are represented in a case. It can also set how the board gives notice of its proceedings, serves papers on the parties, and decides what proof and evidence it will weigh. The law does not require the board to use these powers. It only says the board may use them, and only through this kind of formal order.

This section applies to anyone with a case before the WCAB: injured workers, employers, insurers, and the attorneys or representatives who appear for them. It also applies when a minor or an incompetent person needs someone else to appear on their behalf, since the board's rules on that kind of representation come from this section.

How does this rulemaking power show up in a real workers' comp claim?

The rules the board adopts under this section control how your hearing runs, not how much your claim is worth.

Most workers never read Labor Code 5307 directly, but its effects show up in ordinary parts of a claim. The forms you file, the notice you get of a hearing date, and the way a workers' compensation judge runs a trial all follow procedural rules the board adopted under this authority. Labor Code 5708 says these hearings are governed by this division of the Labor Code and by the rules the board adopts under it, and that the board is not bound by the common law or statutory rules of evidence a civil court must follow. That can let a workers' compensation judge consider records a civil court might exclude.

Does the board have to hold a public hearing before it changes a rule?

Yes. The board can only adopt, amend, or cancel a rule after a public hearing, and a written request for a rule change that sits too long is treated as denied.

Labor Code 5307(b) sets two protections around this power. First, the board cannot adopt, amend, or cancel a rule made under this section without public hearings. Second, if someone files a written request asking the board to change one of its rules, and the board does not set that request for a public hearing to be held within six months of receiving it, the law treats the request as denied. This gives anyone affected by a board rule a real way to ask for a change, and a clock the board cannot ignore forever.

How does Labor Code 5307 connect to the board's rules on evidence?

This section is the source of the board's power to regulate proof and evidence, and two other sections show how that power works in practice.

One of the powers in Labor Code 5307(a) lets the board regulate and prescribe the nature and extent of proof and evidence. Two related sections show what that looks like in practice. Labor Code 5708 says the board is not bound by common law or statutory rules of evidence and can weigh testimony and records in whatever way helps it find the facts and apply the law fairly. Labor Code 5703 lists specific evidence the board may accept, including physician reports and properly authenticated business and hospital records. Together, these sections explain why a workers' compensation hearing can look less formal than a civil trial.

How does Labor Code 5307 relate to the fee schedule sections near it?

Sections 5307.1 and 5307.9 share this section's number but give rulemaking power to a different state official for a different purpose.

Labor Code 5307.1 and Labor Code 5307.9 sit near this section, and both let the administrative director, the state official who runs the Division of Workers' Compensation, rather than the appeals board, adopt fee schedules after public hearings. Labor Code 5307.1 sets the official medical fee schedule for most treatment billing. Labor Code 5307.9 sets the fee schedule for copying and similar record services, and blocks a copy charge when records already on file arrive within 30 days of a request. Both use the same kind of public hearing requirement, but the rulemaking power belongs to the administrative director, not the board.

How does a claim reach a decision under these rules, and what should you save?

A trial before the board ends with a written decision on a timeline set by law, so the paperwork you keep matters more than any single hearing date.

After a trial, Labor Code 5313 requires the judge or the board to issue written findings and an award, order, or decision within 30 days of when the case is submitted, along with a summary of the evidence relied on. The board's wider authority over these proceedings is described in Labor Code 5300, which gives the board exclusive jurisdiction over most workers' compensation disputes.

Keep every notice, order, and form the board or the other side sends you, and note the date each one arrived. If you believe a rule was not followed, for example a notice served the wrong way, write down what happened and raise it with your attorney or the board's Information and Assistance unit.

If a procedural rule, a notice, or an evidence issue is affecting your California workers' compensation claim, write down what happened and when, and keep every notice, order, and form you receive.
