§ 15360 Election Ballot Manual Tally

This law makes election officials do a public hand‑count of a small random sample of ballots (about 1% of precincts or mail‑ballot batches) to check the machine totals.

Key Takeaways

  • •A public hand count must be done on about 1% of precincts or mail‑ballot batches.
  • •The precincts or batches are chosen at random after the polls close, using a random number generator or approved method.
  • •The election office must give at least five days’ public notice of when and where the hand count will happen.
  • •The hand‑count results are included in the official certification, and any differences are fixed using the paper audit trail.

Example

A county has 120 voting precincts and 10,000 mail‑in ballots. After the polls close, the elections official randomly picks 2 precincts (1% of 120 rounded up) and a batch of 100 mail‑in ballots (1% of 10,000) to count by hand in front of the public.

The hand counts are compared to the machine counts. If they match, everything looks good; if they don’t, the paper record is used to fix the numbers.

How to Calculate

Precincts to tally = max(1, ceil(0.01 × total precincts)) Mail‑ballot batches to tally = ceil(0.01 × total mail‑ballot batches)

  1. Find the total number of precincts (or mail‑ballot batches).
  2. Multiply that total by 0.01 (that's 1%).
  3. Round the result up to the next whole number.
  4. If the rounded number is zero, use 1 instead (you must count at least one precinct or batch).

County with 73 precincts and 4,500 mail‑in ballots.

Result: Precincts to tally = max(1, ceil(0.01 × 73)) = max(1, ceil(0.73)) = 1 precinct. Mail‑ballot batches to tally = ceil(0.01 × 45) = ceil(0.45) = 1 batch (about 100 ballots).

§ 15360 Election Ballot Manual Tally

(a) During the official canvass of every election in which a voting system is used, the elections official shall conduct a public manual tally of the ballots tabulated by those devices, including vote by mail ballots, using either of the following methods: (1) (A) A public manual tally of the ballots canvassed in the semifinal official canvass, including vote by mail ballots but not including provisional ballots, cast in 1 percent of the precincts chosen at random by the elections official. If 1 percent of the precincts is less than one whole precinct, the tally shall be conducted in one precinct chosen at random by the elections official. (B) (i) In addition to the 1 percent manual tally, the elections official shall, for each race not included in the initial group of precincts, count one additional precinct. The manual tally shall apply only to the race not previously counted. (ii) The elections official may, at the elections official’s discretion, select additional precincts for the manual tally, which may include vote by mail and provisional ballots. (2) A two-part public manual tally, which includes both of the following: (A) A public manual tally of the ballots canvassed in the semifinal official canvass, not including vote by mail or provisional ballots, cast in 1 percent of the precincts chosen at random by the elections official and conducted pursuant to paragraph (1). (B) (i) A public manual tally of not less than 1 percent of the vote by mail ballots canvassed in the semifinal official canvass. Batches of vote by mail ballots shall be chosen at random by the elections official. (ii) For purposes of this section, a “batch” means a set of ballots tabulated by the voting system devices, for which the voting system can produce a report of the votes cast. (iii) (I) In addition to the 1 percent manual tally of the vote by mail ballots, the elections official shall, for each race not included in the initial 1 percent manual tally of vote by mail ballots, count one additional batch of vote by mail ballots. The manual tally shall apply only to the race not previously counted. (II) The elections official may, at the elections official’s discretion, select additional batches for the manual tally, which may include vote by mail and provisional ballots. (b) The elections official shall use either a random number generator or other method specified in regulations that shall be adopted by the Secretary of State to randomly choose the initial precincts, batches of vote by mail ballots, or direct recording electronic voting machines subject to the public manual tally. (c) The elections official shall not randomly choose the initial precincts or select an additional precinct for the manual tally until after the close of the polls on election day. (d) The manual tally shall be a public process, with the official conducting the election providing at least a five-day public notice of the time and place of the manual tally and of the time and place of the selection of the precincts, batches, or direct recording electronic voting machines subject to the public manual tally before conducting the selection and tally. (e) The elections official shall include a report on the results of the 1 percent manual tally in the certification of the official canvass of the vote. This report shall identify any discrepancies between the machine count and the manual tally and a description of how each of these discrepancies was resolved. In resolving a discrepancy involving a vote recorded by electronic or electromechanical vote tabulating devices, the voter verified paper audit trail shall govern if there is a discrepancy between it and the electronic record. (Amended by Stats. 2023, Ch. 676, Sec. 51. (AB 1219) Effective January 1, 2024.)
