Prawo (ISAP / Dziennik Ustaw)

Official Polish legal acts from the Sejm ELI API (ISAP: Dziennik Ustaw, Monitor Polski). Read the wording of a specific article of a code or statute, together with the source document and date, and a warning about amendments that entered into force later. Check whether an act is in force, find its latest consolidated text (tekst jednolity), list amendments with entry-into-force dates (including upcoming ones), and search acts by title. Shortcuts for the main codes (kp, kc, kk, kpc, ksh, kpa, vat, pit, cit, op…). Use whenever the user asks about Polish law, e.g. "co mówi art. 30 Kodeksu pracy", "okres wypowiedzenia umowy o pracę", "czy ta ustawa obowiązuje", "tekst jednolity ustawy o VAT", "kiedy wchodzą zmiany w Kodeksie pracy", "Dz.U. 2023 poz. 1465", "przepisy o pracy zdalnej".

Prawo (ISAP / Dziennik Ustaw)

Fetches Polish legal acts from the official ELI API of the Chancellery of the Sejm using scripts/prawo.py. Always outputs structured JSON.

Running the script

Run from this skill's directory (or use relative path from repo root):

OSCommand
Linux / macOSpython3 scripts/prawo.py <command> …
Windowspy scripts/prawo.py <command> … (or python)

Zero external dependencies required (standard library only).

Critical: how current is the text?

The API publishes HTML only for some documents. The newest consolidated texts (teksty jednolite) are often PDF-only, and the HTML of an amended act is its original wording from the day it was published. article therefore:

  1. reads the newest consolidated text that has HTML (or the act itself if it was never amended),
  2. reports that document in sourceDocument (ref, date, kind),
  3. lists every amendment that entered into force after that date in amendmentsAfterSource,
  4. sets upToDate and warning.

When upToDate is false, always tell the user the date of the wording and that later amendments exist, and give the PDF link of the newest consolidated text. Never present such text as the certain current wording. For the Constitution the API has no HTML at all: give the PDF link.

Workflow

  1. Article wording ("co mówi art. 30 KP", "okres wypowiedzenia"): python3 scripts/prawo.py article kp 30

    • Article numbers: 30, 22a, 67^18 (superscript 67¹⁸ also works).
    • Quote the text, then state sourceDocument.displayAddress and sourceDocument.date.
    • If upToDate is false, add the warning in your own words and the newest PDF link.

  2. Is the act in force / latest consolidated text / upcoming changes: python3 scripts/prawo.py act kp

    • latestConsolidatedText (with PDF link), amendmentsAfterLatestConsolidatedText, upcomingAmendments (entry into force in the future), status, inForce.

  3. Act by reference: act and article accept a shortcut (kp, vat…), DU/2023/1465, Dz.U. 2023 poz. 1465, Dz.U. 1974 nr 24 poz. 141 or an ISAP address WDU20230001465. List shortcuts with python3 scripts/prawo.py codes (works offline).

  4. Search by title (acts without a shortcut): python3 scripts/prawo.py search "o ochronie danych osobowych" --type Ustawa --in-force

    • Results include amending acts ("o zmianie ustawy…"); pick the act the user means, then call act.

Rules

  • This skill returns legal text, not legal advice. Do not interpret provisions as advice for the user's specific case; suggest a lawyer (adwokat, radca prawny) for that.
  • Always cite the act and the source document, e.g. "art. 36 § 1 Kodeksu pracy (tekst jednolity Dz.U. 2023 poz. 1465)".
  • --original returns the historical wording of an amended act. Use it only when the user asks about the original or historical text, and say so.

Terminy, dni robocze i święta

MITPolandGeneral practice

Polish working days, public holidays and deadlines, computed offline with legal citations. Count working days between dates, get the monthly working-time norm (wymiar czasu pracy) per art. 130 Kodeksu pracy, list statutory holidays (including Wigilia 24 December from 2025), check a single day, compute a deadline such as invoice payment terms (date + N days, moved to the next working day under art. 115 KC), and list monthly tax and social-security deadlines (ZUS, PIT, CIT, VAT/JPK_V7M, PPK) moved off weekends and holidays per art. 12 § 5 Ordynacji podatkowej. Use whenever the user asks e.g. "ile dni roboczych w październiku", "wymiar czasu pracy grudzień", "do kiedy zapłacić ZUS", "termin VAT za wrzesień", "czy 24 grudnia jest wolny", "termin płatności 14 dni od faktury", "kiedy wypada Boże Ciało".
