Warsaw Voivodeship Administrative Court upholds the position of the President of the Personal Data Protection Office concerning the reprimand issued to an MP

In the oral reasons for its judgment of 3 September 2026 (case no. II SA/Wa 2548/25), the court upheld the arguments of the President of the Personal Data Protection Office set out in the decision of 7 October 2025. At that time, the supervisory authority issued a reprimand to Kazimierz Smoliński, a Member of the Sejm of the Republic of Poland, for unlawful processing of personal data.

The Voivodeship Administrative Court found that there was indeed no legal basis for disclosing the data and that the actions taken by the MP were not necessary in view of the purpose he had declared, namely conducting a parliamentary inspection. Mirosław Wróblewski, President of the Personal Data Protection Office, stated in his decision that the MP could have exercised his mandate in a manner that did not compromise the privacy of the data subject.

The disclosure of the data took place during last year's presidential election campaign, in the course of a live-streamed parliamentary inspection concerning a flat that had formerly been owned by the municipality and was at the time privately owned. The MP disclosed a range of personal data that clearly identified the individual, thereby violating their right to privacy.

Further information on the reprimand issued in this case was provided in a press release available here.
