California Invasion of Privacy Act

California's wiretap and eavesdropping law. It makes it a crime, and a basis for a private suit, to tap or read communications in transit without all parties' consent, to record or eavesdrop on confidential communications without all parties' consent, to use pen registers or trap-and-trace devices without a court order, and to use electronic tracking devices to follow a person. Plaintiffs have used these provisions in large numbers of suits over website tracking tools.
