Poland's New Lustration Law Divides the Country It Was Designed to Unite, Reopening Wounds the EU Thought Had Healed

Warsaw has enacted a sweeping lustration law requiring all public officials, judges, and senior civil servants born before 1975 to submit to vetting for communist-era collaboration — a measure that has triggered a constitutional challenge, split the governing coalition, and revived a debate that Poland spent thirty years trying to resolve through deliberate ambiguity.

Poland's relationship with lustration — the vetting of public figures for collaboration with communist-era security services — has been among the most tortured of any post-communist state. The country has passed, struck down, partially implemented, and repeatedly revised lustration frameworks since 1992, never arriving at a stable consensus between those who believe accountability for communist-era collaboration is essential to democratic legitimacy and those who believe that blanket vetting destroys individuals based on decisions made under conditions of coercion that free societies cannot fairly judge.

The law passed in April 2025 is the most expansive lustration framework Poland has ever enacted. It requires all persons born before 1975 who currently hold or seek public office — defined to include judges, prosecutors, senior civil servants, university rectors, and public media directors — to submit a sworn declaration regarding any contact with communist-era security services. Declarations are reviewed by a newly created Lustration Bureau whose members are appointed by the Sejm on a proportional basis, giving the governing coalition effective majority control.

The constitutional challenge was filed within 48 hours of passage by a coalition of former judges, university rectors, and civil society organisations. The challenge argues that the law violates the principle of legal certainty by criminalising failure to disclose contacts that may have been compelled, forgotten, or impossible to document; that the Lustration Bureau's composition gives the governing coalition a structural ability to selectively apply the law against political opponents; and that the 1975 birth-year threshold is arbitrary and discriminatory.

Within the governing coalition, the law has exposed a significant divide between the liberal wing — associated with Foreign Minister Radosław Sikorski, who has said privately that the law is "politically motivated maximalism" — and the Christian democratic wing, which regards lustration as a moral obligation that previous governments evaded for reasons of political convenience. Prime Minister Donald Tusk has declined to take a public position on the constitutional challenge, a silence that both wings of his coalition have interpreted as tacit support for their respective positions.

The European Commission has requested a formal legal assessment from the Venice Commission, the Council of Europe's advisory body on constitutional matters. The Venice Commission's previous opinions on Polish lustration legislation have been consistently critical of broad vetting frameworks, but its opinions are advisory rather than binding.

"We are not punishing people for what they did," said Justice Minister Adam Bodnar. "We are asking people to tell the truth about what they did. That is all. If the truth is uncomfortable, that is the truth's problem, not the law's."
