Nawrocki said he would submit his own legislative proposal "to strengthen the rule of law and the right to a fair trial."
Justice Minister and Prosecutor-General Waldemar Żurek said the bills, passed by parliament last month, were intended to restore public confidence that cases are decided by independent and impartial judges whose appointments are legally sound.
One bill would have changed the way members of the National Council of the Judiciary (KRS), the constitutional body that recommends judges for appointment, are selected.
It proposed that the council’s 15 judicial members be elected in direct, secret ballots overseen by the National Electoral Commission (PKW), rather than by parliament, as has been the case since 2018.
Under the proposal, all judges would have been eligible to vote. Candidates would have been required to have at least 10 years of judicial service and five years of experience in their current court, according to Żurek.
The second bill addressed the legal consequences of judicial appointments made with the participation of the post-2018 National Council of the Judiciary, which critics say was politicised by the previous government.
Żurek said that rulings issued with the participation of so-called "neo-judges" would have remained valid, a provision designed to limit legal chaos and protect the finality of court decisions.
At the same time, the bill would have required fresh competitions for certain judges before a reconstituted panel.
