The San Mateo County Board of Supervisors on Tuesday approved revisions to proposed procedures for the removal of Sheriff Christina Corpus in a process that could take several months.

The board of supervisors approved the process following the passing of a measure allowing them to remove the sheriff accused of misconduct.

The hearing officer’s recommendation, along with a review of the record, would be submitted to the San Mateo County Board of Supervisors for a final decision. Removal would require support from at least four of the five board members. The process is estimated to take at least 3 1/2 months.
