On March 6, a California Superior Court struck down California Election code section 3019(c)(2), which lets election officials invalidate mail ballots if the officials think the signature on the envelope doesn’t match the signature on the voter’s registration form. La Follette v Padilla, San Francisco, CPF 17-515931. The flaw in the law is that the voter is never informed that his or her ballot has been rejected, and therefore the voter has no chance to contest the ruling. Approximately one-half of 1% of all California mail ballots are rejected because officials think the signature is invalid. Here is the opinion. Thanks to Thomas Jones and Rick Hasen for the link.
