Portland, Maine has passed a ballot initiative banning the use of facial recognition by police and city agencies. The Bangor daily news is reporting that voters have passed the ballot initiative.

The initiative follows a city council vote in August, which put a preliminary ban in place as an ordinance. Today’s vote replaces that ordinance with a stronger measure, which can not be revoked for at least five years.

The ordinance was placed on the ballot earlier this year by the Southern Maine chapter of the Democratic socialists of America. It was part of a raft of other progressive initiatives including a $ 15 minimum wage and new limits on rent increases.

The new measure also adds concrete penalties, entitling private citizens to a minimum of $ 1,000 in civil fees if they are surveilled. Violations of the ordinance are also established as grounds for terminate or suspending a city employee.
