SDCL § 40-15-16: Auction agency services available without discrimination--Filing and posting of rate schedules--Rebates prohibited--Violation as petty offense.

Every livestock auction agency shall furnish its service to every person who requests it, without discrimination. Its rates shall be reasonable and nondiscriminating and shall be filed with the Animal Industry Board before a license is issued. The rates may be changed from time to time by filing new schedules with the board thirty days before they are to take effect. Rates shall be posted plainly, visibly, and conspicuously with the license on the premises. No livestock auction agency may rebate any service charge or render its services to anyone without charging the rate posted and filed. A violation of this section is a petty offense. Each violation is a separate offense.
