Digitalization of Appeal Proceedings in Public Procurement in Poland .......... 327

The subject of the article is the presentation of legal solutions for the use of electronic tools in appeal and complaint proceedings in public procurement in Poland. Appeal proceedings are conducted before the National Chamber of Appeals and regulated by the Public Procurement Law, while complaint proceedings, which are proceedings in the second instance, are also regulated by the provisions of the Code of Civil Procedure. The effect of entrusting jurisdiction to administrative and judicial bodies is that there is some differentiation in the legal solutions used in the digitization process, as the Public Procurement Court can use instruments designed for all common courts. Nevertheless, the main direction of digitization includes the area of service and the filing of appeals, complaints and other pleadings, as well as access to case files.
