Prosecutor General Requests Waiver of Mariusz Kamiński's European Parliament Immunity

Poland's Prosecutor General Waldemar Żurek submitted a request on March 31, 2026, to the President of the European Parliament, Roberta Metsola, to waive the parliamentary immunity of Mariusz Kamiński, a PiS member of the European Parliament. The request concerns alleged abuses of power committed by Kamiński between 2007 and 2009, when he served as head of the Central Anticorruption Bureau. The investigation, conducted by the Regional Prosecutor's Office in Lublin, centers on operational-reconnaissance activities carried out without factual or legal basis under the codename "Krystyna." The prosecution intends to bring two separate charges against Kamiński relating to those operations. The move immediately drew a sharp public response from Kamiński himself, who dismissed the request as politically motivated.

Two charges target CBA operations targeting Kwaśniewskis The first charge covers the period from June 2007 to October 13, 2009, and concerns what prosecutors describe as the initiation and approval of groundless operational controls. According to the National Prosecutor's Office, Kamiński ordered CBA officers to conduct activities under the codename "Krystyna," issued urgent operational control orders, and submitted requests to the then-Prosecutor General for consent to order operational control. Prosecutors stated that the purpose of these activities was to realize a premeditated intent to direct criminal proceedings against Jolanta and Aleksander Kwaśniewski, the former Polish president and his wife. The second charge concerns July 2009 specifically, when Kamiński allegedly initiated and ordered an undercover operation involving the covert acquisition of real estate in Kazimierz Dolny, despite the absence of legal prerequisites for such activities. According to the National Prosecutor's Office, an undercover CBA officer purchased the property from a man identified only as Marek M., but the operation failed to achieve its stated goal. The motion to waive immunity stated that the actions taken by Kamiński "from the beginning were aimed at demonstrating that the property belongs to the Kwaśniewski couple" and, contrary to legal provisions, did not aim at detecting the perpetrators of a committed crime but instead led to the creation of a new criminal event.

Mariusz Kamiński served as head of the Central Anticorruption Bureau from 2006 and was later a member of the Polish Sejm across multiple terms, including the III, IV, V, VII, VIII, IX, and X terms, according to his official biography. He became a member of the European Parliament representing PiS in 2024. The Kwaśniewski villa affair has been a recurring point of political controversy in Poland for nearly two decades. According to Kamiński, the Sejm — at the time dominated by the Civic Platform and Polish People's Party coalition — refused to waive his immunity in this same case in 2014, a decision he cited as precedent.

Nowak: activities lacked factual and legal basis from the start Przemysław Nowak, spokesperson for the National Prosecutor's Office, stated that the CBA activities in question lacked both factual and legal basis. Nowak specified that the goal of the operation was supposed to be the confirmation of a thesis assumed by the CBA — that the real owners of the Kazimierz Dolny property were the Kwaśniewskis, held through a front person identified as Marek M. The prosecution's position, as relayed by Nowak, is that the operation did not uncover evidence supporting that thesis. The motion forwarded to Roberta Metsola argues that the activities were not aimed at detecting perpetrators of an already-committed crime but instead effectively created a new criminal event. The European Parliament will now need to consider the request and decide whether to lift Kamiński's immunity before any charges can formally be brought.

Kamiński fires back, citing 2014 Sejm refusal as precedent Kamiński responded to the immunity request on the X platform, describing the move as driven by political hatred rather than legal merit. „Boy, this Żurek sure likes me. He has just sent another request to the European Parliament to waive my immunity. He detected a terrible crime. Almost 20 years ago, as the head of the CBA, I ordered an investigation into the Kwaśniewskis' assets and a clarification of the matter of the villa in Kazimierz.” — Mariusz Kamiński via Do Rzeczy Kamiński pointed out that in 2014, the Sejm — then dominated by the Civic Platform and Polish People's Party — refused to consent to the waiver of his immunity in this same case, arguing that this decision should have closed the matter. He characterized the renewed prosecution effort as an act of political hatred that "blinds them and takes away their reason." Waldemar Żurek has served as Minister of Justice and Prosecutor General since 2025, in the government of Prime Minister Donald Tusk. The case now moves to the European Parliament, where the Committee on Civil Liberties, Justice and Home Affairs — of which Kamiński is a member — may play a procedural role in the immunity proceedings.
