In January, PublicCEO writer Lance Howland wrote about a new wrinkle in local democracy in a new vote-counting method in city elections.

Ranked Choice Voting is a way to bring city voters to the polls only once in a year, eliminating the need for frequent runoff elections. In ranked voting, voters pick their first-, second- and third-choice candidates on a single ballot.

On Tuesday, a federal judge upheld San Francisco’s instant-runoff voting system. San Francisco has used Ranked Choice Voting (also known as Instant Runoff Voting) since 2004.

According to the San Francisco Chronicle:

“A former candidate for supervisor and a group of voters argued that the system, enacted in a 2002 ballot measure, violates the rights of voters who choose only lower-ranked candidates and are disregarded in the final selection.

Courts have upheld instant-runoff voting in other cities, but Seeborg said no judge has ruled before on a system in which voters choose only their top three candidates. Oakland, Berkeley and San Leandro have recently adopted similar measures, he said.
