Oakland voters overwhelmingly voted in a civilian police commission on Tuesday, which will be run by regular people to oversee the Oakland Police Department.
A total of 82 percent of the voters approved Measure LL.
The commission will have powers to investigate police misconduct, impose discipline and hire and fire the chief of police, among other things.
The co-authors of the measure, Oakland Councilmembers Dan Kalb and Noel Gallo, won re-election.
The Oakland police department is currently embroiled in a high-profile police sex abuse scandal, and suffers from accusations, along with other departments in the country, of claims of excessive police force.
Former Oakland Mayor Jean Quan, a progressive, tweeted Wednesday morning that the victory of a soda tax and the police commission "soften the pain" of the results of the national election for her.
There was no formal opposition to Measure LL, although the Oakland Police Officers Association paid for mailers against Kalb and given money to Viola Gonzales, who ran against Gallo, the East Bay Times reported.
