If the State Board or a local board is required to solicit bids from more than one firm, collusive bids are forbidden. If the State Board determines that bids are not genuinely separate and distinct and prepared without communication or collusion between or among bidders, the bids will be rejected. Employes of the State Board or local board, or members of the State Board or local board, may not solicit or accept collusive bids.
