Proposition 65, more formally known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a California law passed by citizen initiative with 63% of the popular vote.

The statute reads:

"No person in the course of doing business shall knowingly discharge or release a chemical known to the state to cause cancer or reproductive toxicity into water or onto or into land where such chemical passes or probably will pass into any source of drinking water…" (CA Health and Safety Code, Section 25249.5)

"No person in the course of doing business shall knowingly and intentionally expose any individual to a chemical known to the state to cause cancer or reproductive toxicity without first giving a clear and reasonable warning…" (CA Health and Safety Code, Section 25249.6)

Proposition 65 provides that the Legislature may amend the law by a two-thirds vote and only "to further its purposes."
