California Code, Civil Code - CIV § 1752

The provisions of this title are not exclusive. The remedies provided herein for violation of any section of this title or for conduct proscribed by any section of this title shall be in addition to any other procedures or remedies for any violation or conduct provided for in any other law.

Nothing in this title shall limit any other statutory or any common law rights of the Attorney General or any other person to bring class actions. Class actions by consumers brought under the specific provisions of Chapter 3 (commencing with Section 1770) of this title shall be governed exclusively by the provisions of Chapter 4 (commencing with Section 1780); however, this shall not be construed so as to deprive a consumer of any statutory or common law right to bring a class action without resort to this title. If any act or practice proscribed under this title also constitutes a cause of action in common law or a violation of another statute, the consumer may assert such common law or statutory cause of action under the procedures and with the remedies provided for in such law.
