12 Miss. Code. R. 9-14.4
Contract arrangements in which the Agency establishes contracts with multiple providers of a single service may only be used when necessary to ensure adequate provision of the personal and professional services required. An Agency shall state its intent to award a contract to multiple bidders, offerors, or applicants in the solicitation document.
Multiple source contracting shall not be made when a single source will meet the Agency's needs without sacrifice of economy or service. Awards shall not be made for the purpose of dividing the business, avoiding the resolution of tie bids, or for making vendor selection available to allow for Agency preference without regard to utility or economy. Any such awards shall be limited to the least number of contractors necessary to meet the valid requirements of the Agency.
