Existing law defines an assault as an unlawful attempt, coupled with present ability, to commit a violent injury upon the person of another. Existing law defines a battery as any willful and unlawful use of force or violence upon the person of another. Under existing law, an assault or battery committed against specified professionals engaged in the performance of their duties, including peace officers, firefighters, and emergency medical personnel, is punishable by imprisonment in a county jail not exceeding one year, by a fine not exceeding $2,000, or by both that fine and imprisonment. This bill would make an assault or battery committed against a utility worker, as defined, who is engaged in the performance of their duties punishable by imprisonment in a county jail not exceeding one year, by a fine not exceeding $2,000, or by both that fine and imprisonment. By expanding the scope of these crimes, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
