The article discussed the question of the correctness of providing a bid bond in the form of a bank (insurance) guarantee in terms of reserving a deadline for payment demands - how this deadline should be set so that the bidder does not suffer negative consequences. An analysis is made of the line of jurispru-dence that is becoming established in public procurement cases, according to which the law allows (or even mandates) the provision of a bond whose expi-ration date falls on the deadline for the submission of bids. According to the author, this solu-tion is correct as the law stands, yet, considering what the law should be, it is incon-sistent with the essence of the bid bond.
