§ 9031 Petition Signature Verification

Key Takeaways

  • •If a petition has almost enough signatures (between 95% and 110% of what's needed), the state will check every signature to make sure they're real.
  • •Signatures won't be thrown out just because someone used initials instead of their full first or middle name.
  • •The state has 60 days (not counting weekends or holidays) to check all the signatures.
  • •If the state finds enough valid signatures early, they can stop checking the rest.

Example

A group collects signatures to put a new law on the ballot. They turn in 10,000 signatures, but only 9,500 are needed.

The state will check all the signatures to make sure they're from real voters. If they find at least 9,500 real signatures, the new law will be on the ballot.

§ 9031 Petition Signature Verification

(a) If the statistical sampling shows that the number of valid signatures is within 95 to 110 percent of the number of signatures of qualified voters needed to declare the petition sufficient, the Secretary of State shall order the examination and verification of the signatures filed, and shall so notify the elections officials. A signature shall not be invalidated because of a variation of the signature caused by the substitution of initials for the first or middle name, or both, of the person signing the petition. (b) Within 60 days, excluding Saturdays, Sundays, and holidays, after receipt of the order, the elections official or registrar of voters shall determine from the records of registration what number of qualified voters have signed the petition, and if necessary the board of supervisors shall allow the elections official or registrar additional assistance for the purpose of examining the petition and provide for their compensation. In determining from the records of registration what number of qualified voters have signed the petition, the elections official or registrar of voters may use any file or list of registered voters maintained by their office, or the facsimiles of voters’ signatures, provided that the method of preparing and displaying the facsimiles complies with law. (c) (1) During the examination and verification of the signatures filed, the elections official or registrar of voters shall submit one or more reports to the Secretary of State showing the number of signatures of qualified voters that have been verified as of that date. The Secretary of State shall determine the number of reports required to be submitted and the manner of their submission. (2) The Secretary of State shall maintain a list indicating the number of verified signatures of qualified voters who have signed the petition based on the most recent reports submitted pursuant to paragraph (1). If the Secretary of State determines, prior to each county’s completing the examination of each signature filed, that based on the list the petition is signed by the requisite number of voters needed to declare the petition sufficient, the Secretary of State shall immediately notify the elections official or registrar of voters of every county or city and county in the state of this fact. Immediately after receipt of this notification, the elections official or registrar of voters may suspend signature verification until receipt of a certificate pursuant to Section 9033 or until otherwise instructed by the Secretary of State. (d) The elections official or registrar, upon the completion of the examination or notification pursuant to paragraph (2) of subdivision (c), shall immediately attach to the petition, except the signatures thereto appended, an amended certificate properly dated, showing the result of the examination and shall immediately transmit the petition, together with the amended certificate, to the Secretary of State. A copy of the amended certificate shall be filed in the elections official’s office. (e) (1) If the amended certificates establish the petition’s sufficiency, the Secretary of State shall certify that the measure is qualified for the ballot as provided in Section 9033. (2) If the amended certificates received from all elections officials by the Secretary of State establish that the petition has still been found insufficient, the Secretary of State shall immediately so notify the proponents and the elections officials. (Amended by Stats. 2023, Ch. 870, Sec. 1. (SB 386) Effective January 1, 2024.)
