DATE WORKING: Tentative. Constitution art. 98(2) and Kodeks wyborczy art. 194 §1: the President orders the election 'nie później niż na 90 dni przed upływem 4 lat od rozpoczęcia kadencji Sejmu', setting it on a 'dzień wolny od pracy, przypadający w ciągu 30 dni przed upływem 4 lat od rozpoczęcia kadencji'; ordering the Sejm election also orders the Senate election (art. 257).

Kodeks wyborczy art. 244 §2 (applied to the Senate by art. 258): the Supreme Court decides by resolution 'nie później niż w 90 dniu po dniu wyborów', i.e. Saturday 5 Feb 2028; art. 9 §2 moves a code deadline that falls on a Saturday or holiday to the next working day, so the window closes at the end of Monday 7 Feb 2028, CET. Protests are due within 7 days of the PKW's publication in Dziennik Ustaw (art. 241). Precedent (one resolution covers Sejm and Senate): 19 Jan 2016 for 25 Oct 2015 (day 86; Dz.U. 2016 poz. 120), 23 Dec 2019 for 13 Oct 2019 (day 71; Dz.U. 2020 poz. 9), 11 Jan 2024 for 15 Oct 2023 (day 88; Dz.U. 2024 poz. 52). No opening is given: the ruling usually comes after the government is formed. These rulings are made by the Supreme Court's Chamber of Extraordinary Control and Public Affairs, whose status is disputed: the government published a later ruling (Dz.U. 2025 poz. 893) with a preface saying that, under ECHR and CJEU judgments, benches that include judges appointed on the post-2017 National Council of the Judiciary's motion are not a court established by law.",
