The registrar of voters gave Brennan wrong information about the number of signatures needed to qualify a proposition for the ballot, causing Brennan to expend more to get more signatures than actually needed to place its proposition on the ballot. Brennan sued the county for the registrar’s negligent misrepresentation. Held, county’s demurrer should have been sustained. Gov. Code 818.8 and 822.2 shield the county from liability for misrepresentations. The county is not liable under Gov. Code 815.6 since no constitutional provision or statute imposes a mandatory duty on the registrar to protect citizens from this sort of harm. The Elections Code does not require the registrar to tell a citizen the number of signatures required. And here, the registrar ultimately used the correct number in certifying the proposition for the election.
