What Is California Labor Code §3602: Exceptions to Exclusive Remedy?

(a) Where the conditions of compensation set forth in Section 3600 concur, the right to recover compensation is, except as specifically provided in this section and Sections 3706 and 4558, the sole and exclusive remedy of the employee or his or her dependents against the employer.

What does Labor Code 3602 mean by "exclusive remedy"?

It means an injured worker usually cannot sue their employer in court. Workers' compensation is the only path instead.

A work injury first has to meet the basic rules in Labor Code 3600. Once it does, the claim moves through workers' compensation, not a lawsuit. Labor Code 3602 is the rule that makes this path exclusive. Fault does not matter here. The worker gives up the right to sue in exchange for no-fault benefits. This rule covers any employer already covered by Labor Code 3600. The size of the business does not change that.

Labor Code 3602 also blocks an old argument called "dual capacity." Some workers argued that an employer who also acted in another role, such as a product maker, could be sued in that other role. Subsection (a) blocks this. Holding another role, before or at the time of the injury, does not create a right to sue the employer. One narrow exception for defective products still exists. It is covered below.

What are the three exceptions listed in Labor Code 3602?

Subsection (b) lists three specific situations. In each one, a worker may sue the employer despite the exclusive remedy rule.

The first exception applies when the employer's own willful physical assault causes the injury or death. This must be a deliberate act. It is not an accident, unsafe equipment, or ordinary carelessness.

The second exception applies when the employer hides an injury that already exists. The employer must also hide how that injury connects to the job. If this hidden fact makes the injury worse, the worker may sue in civil court. But the employer only answers for the added harm, not the original injury. The statute puts the burden on the employer to separate the two.

The third exception applies when a defective product causes the injury or death. The employer must have made that product. The employer must have sold, leased, or otherwise transferred the product to an independent third person for value. That third person must then have given the product to the worker. In-house equipment that never left the workplace does not fit this path. Neither does a product the employer gave the worker directly.

Does Labor Code 3602 close the door on "dual capacity" lawsuits?

Yes, with one exception. Subsection (a) blocks the dual capacity argument itself. Only the defective product path stays open.

Subsection (a) says an employer's other role does not create a right to sue. This closes most dual capacity claims right in the statute's own words. The defective product exception can still apply on its own facts. That is because lawmakers wrote it into subsection (b)(3). It is not because a dual capacity argument wins on its own.

What happens if the Labor Code 3600 conditions are not met at all?

If a claim never qualified under Labor Code 3600, this exclusive remedy rule does not apply. Ordinary liability rules take over instead.

Subsection (c) covers this situation. When the conditions in Labor Code 3600 do not concur, the injury never qualified for workers' compensation. In that case, the employer's liability is the same as if the workers' compensation law never existed. This depends heavily on the facts of the work relationship and the injury. Ask a lawyer to review the details rather than assume either way.

How does Labor Code 3602 connect to Sections 3706 and 4558?

Labor Code 3602 names Sections 3706 and 4558 as its own exceptions. Each one covers a different kind of case.

Subsection (a) points to Labor Code 3706 and Labor Code 4558 as exceptions it does not override. Labor Code 3706 lets a worker sue an employer that never secured workers' compensation coverage at all. Our Labor Code 3706 uninsured employer page explains that path. Labor Code 4558 adds a different lawsuit path. It applies when an employer removes, or knowingly skips installing, a safety guard on a power press. The employer must have specifically allowed that removal, knowing it created a real risk of serious injury or death.

Labor Code 3602 is also easy to confuse with the co-worker rule. Our Labor Code 3601 page covers lawsuits between coworkers. This page covers lawsuits against the employer itself. A worker hurt by a careless outside company has a separate path under Labor Code 3852. See our third-party recovery page for that rule.

These three exceptions are narrow. A civil lawsuit against an employer is also a different legal process from a workers' compensation claim, with its own court and filing rules. Its filing deadline is not the same as a workers' compensation claim deadline, and it depends on the facts of the case, so do not wait to ask a lawyer about timing. Our Labor Code 3600 page explains the basic no-fault rule behind this one.

If your claim was denied, or your employer said none of these exceptions apply without saying why, do not take that answer at face value.
