AB 16: Vote by mail ballots: processing. - California

04/21/25 - Amended Assembly → 09/04/25 - Amended Senate · 5 edits · Sep 4, 2025

MODERATE

The Senate amendment to AB 16 changed the early vote-by-mail ballot processing requirement from mandatory ('shall') to permissive ('may'), removed the state mandate reimbursement provision, and added a coordination mechanism with SB 3 for overlapping amendments to Elections Code Section 15104 regarding public observation of ballot processing. The bill now allows but does not require local elections officials to begin processing mail ballots on the date they are mailed, and includes a new observer access item covering signature verification on cure statements.

Scope change

The bill's scope narrowed from imposing a mandatory early processing requirement on all local elections officials to merely authorizing it. The state mandate reimbursement obligation was eliminated, reducing the financial impact on the state. A new conditional scope was added through the SB 3 coordination mechanism, which could supersede part of the bill's observer access provisions depending on enactment order.

REQUIREMENT

Changed 'shall' to 'may' in Section 15101, making it permissive rather than mandatory for elections officials to begin processing vote by mail ballot return envelopes and ballots on the date they are mailed. Local jurisdictions now have discretion over whether to start early processing.

FISCAL

Removed the state mandate reimbursement provision (former Section 3) that would have required the state to reimburse local agencies if the Commission on State Mandates found costs were mandated. Fiscal notes changed from 'State-mandated local program: yes' to 'no.'

TECHNICAL

Added new Section 2.5 amending Elections Code Section 15104, incorporating changes proposed by SB 3. This section is operative only if both bills are enacted and AB 16 is enacted last, at which point the original Section 2 of AB 16 would not take effect.

Added new Section 3 as a coordination provision specifying that Section 2.5 becomes operative only if both AB 16 and SB 3 are enacted, both amend Section 15104, and AB 16 is enacted after SB 3.

ENFORCEMENT

Added new item (4) to the list of procedures observers may challenge: verifying signatures on statements completed pursuant to subdivisions (d) and (e) of Section 3019 (ballot cure statements).

MINOR

No substantive policy changes were made. The diff reflects a conversion from a formal chaptered document format to a web page display format on the California Legislative Information website. The actual legislative text of AB 16 (amending Elections Code Sections 15101 and 15104 regarding vote by mail ballot processing) is identical in both versions.

TECHNICAL

The document was reformatted from a standalone chaptered bill (with 'STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGAL MATERIAL' header) into a web page layout with navigation elements, metadata, and version history links. No changes to the operative legal text.

MINOR

No substantive policy changes occurred. This diff reflects the standard transition from the enrolled version of AB 16 to its chaptered (signed into law) version, replacing placeholder dates and procedural headers with the official state authentication block, chapter number (Chapter 140), and the Governor's approval date of October 1, 2025.

TECHNICAL

Replaced the enrolled bill header (Assembly/Senate passage dates, clerk signatures, blank Governor receipt line) with the official chaptered bill header including 'STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGAL MATERIAL,' Chapter 140 designation, and approval date of October 1, 2025.

Page headers changed from 'AB 16' to 'Ch. 140' and page numbering was adjusted to match the final published format.

MODERATE

AB 16 was amended to change the timing of vote by mail ballot processing from mandatory to permissive, and to remove the computer capability requirement that previously limited when jurisdictions could begin processing actual ballots. The bill now allows (but does not require) elections officials to process both return envelopes and full ballots starting on the date ballots are mailed, rather than requiring it or limiting ballot processing to 29 days before the election for jurisdictions with sufficient technology.

Scope change

The bill's scope shifted from imposing a uniform mandatory timeline for all jurisdictions (with a technology-based exception) to granting all jurisdictions the option to begin full ballot processing as early as the date ballots are mailed, with no minimum or maximum processing start time imposed by the state.

REQUIREMENT

Changed from mandatory ('shall') to permissive ('may') language for beginning to process vote by mail ballot return envelopes and ballots on the date ballots are mailed. Elections officials now have discretion rather than an obligation.

Removed the computer capability requirement that previously allowed only jurisdictions with sufficient technology to process full ballots 29 days before the election, and removed the fallback rule requiring all other jurisdictions to wait until 5 p.m. on the day before the election to begin processing ballots.

SCOPE

The bill is no longer classified as a state-mandated local program (changed from 'yes' to 'no') because the processing requirement is now permissive rather than mandatory, which affects fiscal reimbursement obligations under the California Constitution.

TECHNICAL

Section 15104 changed 'before they are counted on election day' to 'before they are counted' to reflect that ballots may be processed and counted at various times before election day rather than only on election day itself.

MINOR

This diff reflects the transition of AB 16 from its Senate-amended working draft to the final enrolled version ready for the Governor's signature. No substantive policy changes were made; the differences are entirely formatting and procedural, including removal of line numbers, amendment headers, and the 'as amended' designation in the digest.

TECHNICAL

The bill was reformatted from a working legislative draft (with line numbers, amendment dates, and committee routing) into the final enrolled format with chapter number placeholder and Governor approval block.

The legislative counsel's digest changed from 'AB 16, as amended, Alanis' to 'AB 16, Alanis', removing the 'as amended' designation now that this is the final version.
