(a) A person that violates this title shall be subject to an injunction and liable for a civil penalty of not more than two thousand five hundred dollars ($2,500) per affected child for each negligent violation or not more than seven thousand five hundred dollars ($7,500) per affected child for each intentional violation, which shall be assessed and recovered only in a civil action brought in the name of the people of the State of California by the Attorney General.
