Existing law prohibits a person from locating or positioning a weighing or measuring device used in retail trade so that its indications cannot be accurately read by the purchaser under ordinary circumstances, except as specified. A violation of this prohibition is a misdemeanor. This bill would revise and recast that prohibition to instead prohibit a person from locating or positioning a weighing or measuring device used for commercial purposes, as defined, so that its indications cannot be accurately read by the customer and operator under ordinary circumstances, except as specified. To the extent that the bill would expand the definition of a crime, the 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.
