The Subletting and Subcontracting Fair Practices Act (Public Contract Code section 4100 et seq.), also known as the Listing Law, is intended to prevent direct contractors on public works projects from “bid shopping” and “bid peddling.”
Bid Shopping: Bid shopping is when a direct contractor discloses a subcontractor’s bid to other subcontractors in an attempt to obtain a lower bid than the one in which it based its bid to the owner.
Bid Peddling: Bid peddling is the other side of the equation. It is when a subcontractor whose bid was not selected, lowers its bid in an attempt to induce the direct contractor to substitute it for another subcontractor after the prime contractor’s bid has been awarded.
