Proposition F adopted by the voters on November 5, 2019, included amendments prohibiting campaign contributions from certain entities and expanding disclaimer requirements for independent expenditure committee advertisements, including the disclosure of 'secondary contributors' where top committee contributors must also disclose their top contributors.

The ordinance amends the Campaign and Governmental Conduct Code to conform to a court order, creating exceptions to the requirement to disclose secondary contributors for smaller or shorter advertisements; specifically print advertisements 25 square inches or smaller, and spoken disclaimers in audio or video advertisements that are 30 seconds or less.

The preliminary injunction granted by the court in response to a constitutional challenge affects the application of disclaimer requirements for specific types of advertisements, necessitating modifications to existing legislation.

To comply with the court's order following the challenge to the constitutionality of Proposition F's disclaimer requirements, particularly the required disclosure of secondary contributors for certain types of campaign advertisements.

Amendments can be made if they further the purposes of the Code, are approved by the Ethics Commission by at least a four-fifths vote, are available for at least 30 days for public review before being considered by the Board of Supervisors, and are approved by at least a two-thirds vote of all Board members. The Ethics Commission approved this ordinance on December 9, 2022, by a vote of 4-0, and it has been available for public review for at least 30 days before consideration by a committee of the Board of Supervisors.

The ordinance becomes effective 30 days after enactment, which occurs when the Mayor signs the ordinance, when it’s returned unsigned, when the Mayor does not sign it within ten days of receipt, or when the Board of Supervisors overrides the Mayor's veto.
