Elections.

(1) Existing state and federal law provides for the enforcement of laws related to elections. This bill would prohibit a peace officer from interfering with the administration of an election, as specified. This bill would authorize certain persons to enforce those prohibitions by filing a civil action, as specified. This bill would also prohibit any individual from permitting an agent of a law enforcement agency, as specified, to access, disrupt, modify, or take possession of rosters, combined rosters, or voter lists unless authorized by a court order or to investigate certain types of voting fraud. The bill would additionally require the Attorney General to provide guidance and information regarding how to respond to requests by law enforcement, as defined, to access areas where ballots are present. (2) Existing law requires an elections official, upon receiving a vote by mail ballot, to compare the signature on the identification envelope with the voter's prior signatures, and it also provides a mechanism by which a voter can verify their signature and cure this defect. Existing law provides that the processing of vote by mail ballots is open to the public and permits specified persons and organizations to observe this processing. This bill would prohibit a vote by mail observer from challenging a signature on a vote by mail ballot that has been verified by the voter. (3) Under existing law, it is a crime for a person in possession of a firearm, a uniformed peace officer, private guard, or security personnel, or any person wearing the uniform of a peace officer, guard, or security personnel, to be stationed in the immediate vicinity of, or posted at, a polling place without authorization from the appropriate elections official. It is also a crime for a person to hire or arrange for such a person to be stationed in the immediate vicinity of, or posted at, a polling place without authorization from the elections official. This bill would authorize the Secretary of State or Attorney General to object to authorization provided by the appropriate elections official, in which case the person stationed or posted at the polling place, or the person who hired or arranged for such a person to be stationed or posted at the polling place, is guilty of a crime. By expanding the scope of these crimes, the bill would create a state-mandated local program. (4) Existing law authorizes the Secretary of State, Attorney General, and any local elections official in the county in which the act occurs, to bring a civil action against an individual, business, or other legal entity that commits any specified act of tampering with a voting system or voting equipment before, during, or after an election. This bill would additionally authorize the Secretary of State, Attorney General, and the appropriate local elections official to bring a civil action against a person, business, or entity that takes a package containing ballots from the custody of an elections official. (5) Existing law makes it a crime for an individual to undertake a number of enumerated actions that would result in interference with an election, including displaying a container for the purpose of collecting ballots with the intent to deceive a voter into casting a ballot in an unofficial ballot box. This bill would also make it a crime to take a package containing voted ballots out of the custody of an elections official. By expanding the scope of this crime, the bill would impose a state-mandated local program. (6) Existing law requires the elections official of any county or city using a voting system to inspect the machines or devices at least once every 2 years. This bill would prohibit an individual from permitting an agent of a law enforcement agency, as defined, to access, disrupt, modify, or take possession of certified voting technology unless authorized by a court order. To the extent this bill would establish new procedures for the conduct of elections, it would create a state-mandated local program. (7) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that with regard to certain mandates no reimbursement is required by this act for a specified reason. With regard to any other mandates, this bill would provide that, if the Commission on State Mandates determines that the bill contains costs so mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above. (8) This bill would declare that it is to take effect immediately as an urgency statute.

Protein products.

Existing law, the Sherman Food, Drug, and Cosmetic Law, under the administration and enforcement of the State Department of Public Health, provides for the regulation of various subjects relating to the manufacturing, processing, labeling, advertising, and sale of food, drugs, and cosmetics. Existing law places product testing and disclosure requirements on various products, including baby food and prenatal vitamins. A violation of the Sherman Food, Drug, and Cosmetic Law is punishable as a misdemeanor. This bill would, commencing January 1, 2028, require a manufacturer of a bulk protein product or a packaged protein product, as defined, that is sold, manufactured, delivered, held, or offered for sale in this state to test a representative sample of each lot of the product for heavy metals, as defined. The bill would require both a manufacturer and brand owner to provide test results to an authorized agent of the department upon their request, as specified. The bill would, commencing January 1, 2028, require a brand owner of a packaged protein product that is sold, manufactured, delivered, held, or offered for sale in the state to disclose specified product information to the public, including, among other things, the heavy metal testing information. Commencing on or after January 1, 2028, the bill would require a statement regarding heavy metal testing to be included on the outermost package of a packaged protein product sold in a retail store and on the product details page on an internet website for products sold online or directly to consumers. The bill would, commencing January 1, 2028, prohibit a person from selling in the state or manufacturing, delivering, holding, or offering for sale in the state a protein product that does not comply with these provisions. By creating a new crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

Initiative and referendum measures: title and summary.

Existing law requires the Attorney General, upon receipt of the text of a proposed initiative or referendum measure, to prepare a circulating title and summary of the chief purposes and points of the proposed measure that includes an estimate of the financial impact of the proposed measure. Existing law requires the Attorney General to prepare a ballot title and summary for each measure that the Secretary of State determines will appear on the ballot at a statewide election. This bill would instead require the Legislative Analyst to carry out these responsibilities. The bill would make the operation of this requirement contingent upon approval by the voters of SCA 3 of the 2025–26 Regular Session. The Political Reform Act of 1974, an initiative measure, provides that the Legislature may amend the act to further the act's purposes upon a 23 vote of each house of the Legislature and compliance with specified procedural requirements. The act also provides that, notwithstanding this requirement, the Legislature may add to the voter information guide information regarding candidates or other information. This bill, which would permit or require additional information to be included in the voter information guide, would therefore require a majority vote.

A resolution to propose to the people of the State of California an amendment to the Constitution of the State, by amending Sections 9 and 10 of, and adding Section 7.5 to, Article II thereof, and by amending Section 8 of Article IV thereof, relating to elections.

The California Constitution provides that the electors may propose a statute or an amendment to the California Constitution by initiative and approve or reject a statute by referendum. An initiative measure may be proposed by presenting to the Secretary of State a petition that sets forth the text of the proposed statute or amendment to the Constitution and is certified to have been signed by the required number of electors, as prescribed. A referendum measure may be proposed by presenting to the Secretary of State a petition that sets forth the statute or part of the statute to be submitted to the electors, and is certified to have been signed by the required number of electors. Before the circulation of an initiative or referendum petition for signatures, the California Constitution requires that a copy of the petition be submitted to the Attorney General, who must prepare a title and summary of the measure. Existing statutory law also directs the Attorney General to prepare the ballot label and the ballot title and summary that is included in the state voter information guide for each measure that appears on a statewide ballot. This measure would transfer from the Attorney General to the Legislative Analyst the duty of preparing the title and summary for a proposed initiative or referendum. The measure would also require, for each measure that appears on a statewide ballot, the Legislative Analyst to prepare the ballot label and the ballot title and summary for the state voter information guide.
