Abstract
The Public Procurement Law of 11 September 2019 introduced a number of major changes to the appeals procedure. Particular attention should be paid to new solutions concerning the composition of the adjudicating Chamber, the exclusion of a member of the adjudicating panel from resolving a certain appeal under the Law, extending the scope of legal protection measures, the issue of powers of attorney in proceedings before the Chamber, issues related to evidence in appeal proceedings, as well as the possibility of appealing against the decisions of the president of the National Appeals Chamber. The amendments introduced by the new regulation are aimed at streamlining the course of appeal proceedings and increasing the effectiveness of the Chamber’s decisions.
