In a pivotal moment for Poland and the European Union, Karol Nawrocki, an ultra-right candidate from the Law and Justice (PiS) party, emerged victorious in the recent presidential elections, narrowly defeating Rafal Trzaskowski, Warsaw's mayor and a staunch pro-European advocate. This outcome, decided by a slim margin of 400,000 votes in a nation of 38 million, delivers a substantial blow to the government led by Donald Tusk and poses significant challenges for the EU.

Nawrocki's triumph marks a new episode in Poland's ongoing constitutional crisis, a saga that began in 2015 with PiS's aggressive maneuvers against the country's democratic foundations. For eight years, the government exerted control over judges, officials, prosecutors, and public television, instigating a direct confrontation with European institutions and threatening the EU's legal framework. Tusk's coalition rose to power in 2023 with pledges to restore institutional stability, judicial independence, and strengthen ties with Europe. However, these reforms have remained elusive.

The Polish constitution endows the president with critical powers: vetoing legislation and referring laws to the constitutional tribunal. President Andrzej Duda, aligned with PiS, has wielded these powers to obstruct the legislative agenda of Tusk's government. Nawrocki's presidency, with pledges to block efforts to reverse judicial reforms, represents a substantial setback for Poland's democratization efforts.

These elections plunge Poland into a phase of profound political instability, carrying ramifications for the EU. Firstly, the weakened Polish government, with only two years left in its term, may struggle to advance its European agenda. Poland, a key EU member, has been a staunch Ukrainian ally since 2022. Secondly, Nawrocki's win is a victory for the governments of Hungary and Slovakia, who gain a crucial ally in their resistance against EU institutions, and for Donald Trump, whose administration supported Nawrocki's campaign.

Finally, the EU must reassess its approach to member states that violate community norms. Following Tusk's victory, Brussels signaled trust in Warsaw by lifting sanctions and releasing previously withheld funds. Nawrocki's success resets Poland's position, reigniting debates on the legal, economic, and political tools needed to restore institutional normalcy. At stake is the survival of the Union itself, whose legal integrity relies on the uniform application of rules and the independence of courts across its 27 member states.
