The aim of the article is to discuss the grounds for the exclusion of a public procurement contractor in the event of bankruptcy of the original contractor. The article presents the CJEU position on the acceptability of a change of contractor of a public contract in the event of bankruptcy of the original contractor. The issued ruling affects the application of the provisions of the Act of 11 September 2019 — Public Procurement Law as the national rules on amendments to the Public Procurement Law reflect the Art. 72 of the Directive 2014/24/EU. The CJEU examined whether in the light of Art. 72 para. 1(d)(ii) of the Directive 2014/24, a change of contractor is possible in the event of insolvency of the original contractor leading to its compulsory liquidation. Analysis of the position of the CJEU and the provisions of the Act of 28 February 2003 Bankruptcy Law1 makes it possible to confirm that the permissibility of changing the public contract also includes insolvency as an extraordinary way of terminating economic activity.

The commented ruling of the ECJ has practical implications for the public procurement market in the Member States. The ECJ examined whether in the situation when grounds for exclusion arise in relation to a subcontractor, the contracting authority may exclude from the procedure the contractor who indicated the subcontractor in its tender. The aim of the article is to show the correct procedure of the contracting authority in a situation where the grounds for exclusion concern subcontractors. The ECJ confirmed the compliance with EU law of national regulations providing for the possibility of examining exclusion criteria also in relation to subcontractors. However, according to the principle of proportionality, the contracting authority must be able to assess whether the economic operator is able to perform the contract without the subcontractor's participation before the exclusion of the economic operator. Thus, the ECJ ruled that national legislation providing for the automatic character of such exclusion are incompatible with EU law.

The purpose of the amendments introduced by the
Act of 31 July 2019 amending certain acts in order to
reduce the regulatory burdens, called the deregulatory
act, is to reduce unnecessary and excessive regulatory
burdens. New provisions are to improve the succession
by enabling or improving the exercise of rights in
relation to assets of an enterprise when the share in
the enterprise is included into an estate from a
deceased spouse of the sole trader. The deregulation
act provides for the amendment to the Act on the
succession administration of an enterprise of a natural
person to reduce inaccurate and excessive regulatory
burdens, in particular, those of an administrative
nature.
