The attention is paid to the optional ground based on art. 24 sec. 5 point 4 of the Polish Act of January 29, 2004, Public Procurement Law, according to which the contracting authority may exclude from the procurement procedure contractors who, for reasons attributable to them, failed to perform or to a significant extent improperly performed a prior public procurement contract or concession contract concluded with the contracting authority, which led to termination or awarding compensation. In order to be able to use the institution, the contracting party must include an appropriate clause in the contract, providing for the possibility of terminating the contract or awarding damages due to contractor’s non- performance or improper performance of the contract, which is a common practice on the Polish public procurement market. However, in the event of such a clause, the contracting authority is obliged to apply it if the condition is met.
