Polish prosecutor moves to detain MP Michał Woś and strip immunity from Łukasz Mejza in twin cases of alleged fraud and obstruction

Two requests hit the Sejm on one day

Prosecutor General Waldemar Żurek handed two separate requests to Marshal of the Sejm Włodzimierz Czarzasty on 23 July 2026. One asks for permission to detain and forcibly bring MP Michał Woś (PiS) before prosecutors, while the other seeks to lift the parliamentary immunity of MP Łukasz Mejza so that criminal proceedings against him can move forward. Both investigations are led by the Regional Prosecutor's Office in Poznań.

Prosecutor General spokesperson Anna Adamiak confirmed the filings in a statement issued on Thursday.

Why prosecutors want to detain Michał Woś

Michał Woś had already waived his formal immunity on 4 May 2026, consenting to criminal liability. That allowed prosecutors to issue a decision to charge him and to summon him for questioning as a suspect. The first summons was set for 28 May, but because Woś received the notice a day later his absence was treated as excused.

Three more dates followed: 30 June, 6 July and 14 July. Prosecutors state that Woś personally collected all three summonses on 22 June. He did not appear on any of the dates and provided no justification. He also sent letters asking for the proceedings to be moved to a different prosecutor's office, a request the prosecutor refused. According to the prosecutor's office, Woś then declined to accept a follow-up decision delivered by police officers and ignored telephone calls.

"The analysis of his conduct indicates deliberate and intentional obstruction of the proceedings," Adamiak said.

Personal immunity still shields an MP from detention even after the formal immunity is lifted. Because a fifth summons would likely be ignored, the prosecutor decided that only detention and compulsory escort would allow the charge to be formally announced and the interrogation to proceed.

The substance of the Woś case

Investigators suspect that between 2021 and 2023, while serving as deputy justice minister overseeing the Prison Service, Woś exceeded his powers and failed to fulfil his duties. The probe covers early award of officer ranks to individuals who did not meet statutory criteria, appointments that sidestepped required procedures, approval of an adviser post inside the Prison Service, granting a Warsaw flat to that adviser, and creation of a fourth deputy director-general post at the Prison Service that the prosecutor says was unjustified by the service's needs.

Woś has previously rejected the allegations as politically motivated.

The Mejza immunity push

Prosecutors want to charge Łukasz Mejza with three offences: fraud, certifying falsehoods in documents, and subsidy fraud. The case revolves around e-learning training projects for employees of micro, small and medium-sized enterprises, financed in part by the EU and run between 2019 and 2021.

The two programs named in the filings are "Lubuskie Bony Rozwojowe w subregionie zielonogórskim - edycja II" and "Lubuskie Bony Szkoleniowe w subregionie gorzowskim - edycja II". They were administered by the Lubusz Voivodeship and carried out by the Regional Development Agency in Zielona Góra (ARR) and the Western Chamber of Industry and Commerce in Gorzów Wielkopolski.

Investigators allege that between March and August 2020 Mejza, operating under the business name "Future Wolves Łukasz Mejza", acted with another person to mislead the ARR about how participants' own contributions were financed and about the recruitment rules. False information was also allegedly entered in invoices submitted for costs that should not have been reimbursed.

The ARR is said to have suffered a disadvantageous disposal of property worth PLN 66,250, with actual damage of PLN 49,687.50. A separate source report puts the loss figure above PLN 100,000.

The evidence gathered in the case provided a sufficiently justified suspicion that the MP committed three separate acts, each fulfilling the elements of fraud, certifying falsehoods in a document and subsidy fraud.

Until the Sejm votes to lift Mejza's immunity, or Mejza himself renounces it, prosecutors cannot formally charge him. The same batch of filings also included a request concerning PiS MP Michał Woś.

What happens next

Both requests now sit with the Marshal of the Sejm. The Chamber will have to schedule votes on the immunity waiver for Mejza and on the detention consent for Woś. The prosecutor's office has made clear that both steps are procedural gateways; without a vote, neither case can advance to the formal charging stage.
