California Experimental Subject’s Bill of Rights: Consent and Penalties

If you are asked to join a medical experiment in California, state law entitles you to a written document called the Experimental Subject’s Bill of Rights. It lists ten specific protections you have before you agree to anything, and you must receive it, sign it, and date it before the experiment begins. The document has to be in a language you speak fluently. It comes from the Protection of Human Subjects in Medical Experimentation Act, codified at California Health and Safety Code section 24170 and following, and it applies at every research site in the state, from university hospitals to private clinics.

The Ten Rights You Must Be Given

Section 24172 of the Health and Safety Code sets out the list. The statute says the bill of rights “includes, but is not limited to,” these ten items, so a researcher can add protections but cannot subtract any.

To be told the nature and purpose of the experiment.
To receive a clear explanation of every procedure you will undergo and any drug or device that will be used on you.
To be told about any pain, discomfort, or risks that can reasonably be expected.
To have any benefits you might personally gain explained to you.
To learn about alternative treatments, drugs, or devices that might help you, and how their risks and benefits compare.
To know what medical care, if any, is available to you if something goes wrong during or after the experiment.
To ask any question about the experiment or its procedures at any time.
To withdraw at any time, for any reason, without losing any care or benefits you are otherwise entitled to.
To receive a copy of the consent form you signed and dated.
To make your decision without force, fraud, deception, pressure, or manipulation.

Researchers sometimes fold this into an “information sheet” during enrollment, but the law treats it as a standalone legal document, separate from the consent form. You should get it, read it, and sign it before anything else happens.¹

When the Bill of Rights Applies

The Act defines “medical experiment” broadly, and the definition covers a lot more than drug trials. Three types of activity trigger every protection in the chapter:

Any cutting, penetrating, or damaging of tissue, or the use of a drug, device, radiation, heat, cold, or biological substance on a person, when the procedure is not reasonably related to maintaining or improving that person’s health.
The use of any drug or medical device that has not yet received full regulatory approval.
Withholding medical care from a person for any reason other than protecting or improving that person’s health.

Purpose is what distinguishes the categories. A procedure your doctor performs to treat your condition is standard care. The same procedure performed to generate research data, with no direct benefit to your health, is a medical experiment and pulls in every requirement of the Act.²

The Consent Form Is a Separate Document

The bill of rights and the consent form are two different documents, and the law requires both. After you receive the bill of rights, a written consent form must be prepared. It must explain the experiment to you in plain language, both verbally and in writing. Under Section 24173, the consent form has to include at least these disclosures:

The procedures, drugs, or devices involved, and their purposes. If some participants will receive a placebo, the form must say so, though it does not have to tell you whether you personally will get one.
The discomforts and risks you can reasonably expect.
Any benefits you might personally receive.
Alternative treatments and how their risks and benefits compare.
An estimate of how long recovery will take.
An offer to answer your questions.
A clear statement that you can withdraw at any time without penalty.
The name, institutional affiliation, and address of the person conducting the experiment.
The name of the sponsor, funding source, or manufacturer, and the organization overseeing the research.
Contact information for an impartial third party, not connected to the experiment, where you can direct complaints.

Two details on that list catch people off guard. Researchers must disclose that a placebo arm exists but do not have to tell you whether you are in it. And the complaint contact cannot be someone involved in the research.³

When Someone Else Can Consent for You

The default rule is simple: no one can be enrolled in a medical experiment without their own informed consent. The law recognizes that some people cannot give it, and it lays out who can step in. If you are under a conservatorship, the process depends on whether a court has found that you lack capacity to consent to medical treatment, and on which type of conservatorship applies. Different Probate Code and Welfare and Institutions Code rules govern those different situations.⁴

One limit applies across the board. A conservator, guardian, or other representative can only consent to experiments related to maintaining or improving the subject’s health, or to obtaining information about the subject’s own condition. A surrogate cannot volunteer an incapacitated person for research that benefits only science in general.

At institutions that hold a federal assurance with the U.S. Department of Health and Human Services, Section 24178 also allows a surrogate decision-maker to provide consent if you are unable to consent yourself and do not resist participation. The statute sets a strict priority order that runs from an agent under an advance health care directive down through spouse, registered domestic partner, adult child, custodial parent, adult sibling, adult grandchild, and finally the nearest available adult relative. Disagreement at the same level means no consent; a higher-priority person’s refusal cannot be overridden from below.⁵

Waivers Are Void, and Violations Have Real Penalties

Any language in a consent form or enrollment agreement that purports to waive your rights under the Act is legally meaningless. It does not matter whether you signed it, a conservator signed it, or anyone else did. The Act also preserves your right to recover damages under any other applicable law, so the statutory penalties below are a floor.

Civil Damages

A researcher who negligently allows an experiment to proceed without your informed consent is liable for damages of $500 to $10,000, as determined by a court. If the failure was willful, the range jumps to $1,000 to $25,000. Each experiment conducted in violation counts as a separate offense, so a researcher who enrolls multiple subjects improperly faces those penalties per subject.

Criminal Penalties

When a researcher willfully skips informed consent and that failure exposes you to a known, substantial risk of serious physical or psychological harm, the conduct becomes a misdemeanor punishable by up to a year in county jail, a fine of up to $50,000, or both. The same criminal penalty reaches pharmaceutical company employees who are directly responsible for contracting out a medical experiment and who knowingly withhold information about risks from the person conducting the research.⁶

Federal Rules Sit on Top, Not Instead

Most major California research institutions also operate under the federal Common Rule at 45 CFR Part 46, which requires its own informed consent process, Institutional Review Board approval, and extra safeguards for pregnant women, prisoners, and children.⁷ Section 24178 exempts researchers at federally assured institutions from most of the California chapter, but two provisions still apply: Section 24172 (the bill of rights) and Section 24176 (the penalties). You are still entitled to the California document, and a violation still exposes the researcher to California’s civil and criminal penalties, regardless of federal compliance. FDA-regulated drug and device trials add another layer of consent requirements under 21 CFR Part 50.⁸

How Long You Have to File a Claim

California Code of Civil Procedure section 340 sets a one-year statute of limitations for actions to recover a penalty created by statute, unless the statute itself provides a different deadline. The Protection of Human Subjects Act does not specify its own period, so the one-year window applies to Section 24176 claims. The clock generally starts when you discover, or reasonably should have discovered, the violation. If you think an experiment went forward without your proper consent, that deadline is short, and missing it can bar the claim entirely.⁹
