    Kodeks wyborczy art. 238 (Sejm) and art. 276 (Senate): the PKW 'ogłasza w Dzienniku Ustaw ... w formie obwieszczenia oraz podaje do publicznej wiadomości wyniki wyborów'. No deadline is set. Precedent from Dziennik Ustaw: obwieszczenia dated 27 Oct 2015 (day 2; 2015 poz. 1731-1732), 14 Oct 2019 (day 1; 2019 poz. 1955-1956) and 17 Oct 2023 (day 2; 2023 poz. 2234-2235, promulgated 18 Oct). The PKW posted the 2023 Sejm notice at 19:19 CEST on 17 Oct (pkw.gov.pl change log). The opening (12:00 CET Monday 8 Nov 2027) is an ESTIMATED floor from the 2019 day-1 case; the window closes at the end of Sunday 14 Nov 2027, CET, five days after the latest precedent.

    Constitution art. 101(1): 'Ważność wyborów do Sejmu i Senatu stwierdza Sąd Najwyższy.' 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.

    Constitution art. 109(2): the President convenes the first sittings of the Sejm and Senate 'na dzień przypadający w ciągu 30 dni od dnia wyborów' (by 7 Dec 2027). Art. 154(1): the President appoints the prime minister and the cabinet 'w ciągu 14 dni od dnia pierwszego posiedzenia Sejmu', and the cabinet must win a confidence vote within 14 days (art. 154(2)); failing that the Sejm elects a prime minister (art. 154(3)), then the President tries again (art. 155), and a further failure dissolves the Sejm. No cabinet before the first sitting; the opening here is the ESTIMATED final-result floor. Precedent: first sittings 12 Nov 2015, 12 Nov 2019 and 13 Nov 2023 (api.sejm.gov.pl).
