Maintains the text in force

The Chancellery of the Sejm's statute collection. The same corpus is served at three addresses and they do not behave alike. isap.sejm.gov.pl is the public web front end; dziennikustaw.gov.pl, run by the Rządowe Centrum Legislacji, serves the Dziennik Ustaw as published; and api.sejm.gov.pl/eli is a machine interface over the same material, giving each act an ELI of the form DU/YYYY/N with its status, its entry into force, its repeal date, the acts that amended it, the consolidated texts announced for it, and the amendments made after each of those. Every act is served in up to four editions: O, the text as published in the Dziennik; T, the announced consolidated text; and U, the Chancellery's own tekst ujednolicony, which carries every amendment and prints on every page the date it was generated and, at its head, the list of Dziennik positions it was built from. The U edition also marks pending amendments in the body: words still in force are in square brackets and the wording that will replace them is in angle brackets, with a marginal note naming the amending Act and its commencement.

Maintains the current text of the law as amended, so you can read a provision as it stands today rather than reconstructing it from amendments.

Cannot be cited for

**isap.sejm.gov.pl cannot be read by this project at all, and it fails without saying so.** A request for a document page answers HTTP 200 with an Imperva interstitial headed "Pardon Our Interruption"; a request for a PDF answers HTTP 200 with `Content-Type: application/pdf` and an Incapsula JavaScript challenge in the body, so a naive client stores an HTML page under a .pdf name and a PDF tool reports the file as corrupt rather than as blocked. The same documents come back intact from api.sejm.gov.pl, which is why every citation here uses that address. The tekst ujednolicony is the Chancellery's own consolidation and is not an official text; the Dziennik Ustaw as published governs. Its angle-bracket marking cannot be relied on to say what is in force today: the consolidation of the Ustawa o kierujących pojazdami generated on 1 October 2026 still marks a change to article 11(1)(5) as taking effect on 3 September 2026. It may not be cited for the amounts in instruments that delegate them - the Ustawa o pomocy społecznej prints 461 and 316 złoty with a footnote saying the current figures are announced by the minister - nor for anything the Chancellery does not publish: the district lists of occupations closed to work permits are kept in a register under article 31(6) of the 2025 employment Act and are not here, and ministerial announcements under article 9(7) of the social assistance Act are published in Monitor Polski.

The Dziennik Ustaw publishes daily. A tekst ujednolicony is regenerated when the act is amended and prints the generation date on every page; the ELI record carries a changeDate of its own.
