2004 California Proposition 64

Proposition 64 was a California ballot proposition on the November 2, 2004 ballot. It passed with 6,571,694 (59.0%) votes in favor and 4,578,725 (41.0%) against. It was an initiative statute that limited the California law on unfair competition, restricting private lawsuits against a company only to those where an individual is injured by and suffers a financial loss due to an unfair, unlawful, or fraudulent business practice and providing that otherwise only public prosecutors may file lawsuits charging unfair business practices.

Proponents argued that the measure would limit "frivolous lawsuits" against companies, which they claimed result mainly in a windfall for lawyers rather than consumers. Proponents also argued that businesses ultimately must pass along their costs in the form of higher prices to consumers.

Opponents charged that the proposition was heavily funded by businesses who wanted to weaken consumer rights by limiting Californians' ability to enforce environmental, public health, and consumer protection laws such as 1986's Proposition 65.
