Mississippi Code Title 19. Counties and County Officers § 19-13-113

If it appears to the satisfaction of the board of supervisors, on any opening of bids, that there has been a combination between the bidders or that some of them are connected with a trust or combine, or that the bidding is purposely unfair, in raising the prices of some articles and lowering those of others out of proportion so that it is difficult to determine which of the bids is the lowest and best, all bids may be rejected and new bids shall be called for and requested.
