Repertorium

Repertorium is for lawyers and legal teams who use ChatGPT or Codex for research in Polish and European Union law and need every answer tied to a source they can check.

It gives the model read-only access to:

• Polish statutes and regulations, with their consolidated texts;
• judgments of Polish courts: the Supreme Court, administrative courts, common courts and the National Appeals Chamber;
• judgments of the Court of Justice of the EU;
• Polish individual tax rulings;
• a computed graph of citations between these documents, including links between Polish acts and the EU acts they implement or cite.

Every result carries a stable document identifier, its source and a character-level locator, so each quotation can be checked against the original.

What you can do:

• find a provision or a judgment and read the exact passage;
• see which court rulings cite a given provision;
• check the case numbers, dates and statutory provisions cited in a draft brief or opinion;
• see when an article of a Polish act was amended and by which act;
• trace the EU acts that a Polish statute implements or cites;
• find the Polish translation of a European Court of Human Rights judgment and a link to HUDOC, the Court's official case-law database;
• ask how far each source reaches in time and what the corpus does not contain.

Repertorium also reports the limits of what it knows. When a case number is absent from the corpus, it says so, and that does not prove the judgment does not exist. Citation lists say when they are partial. Most documents are in Polish; EU acts are available in Polish or English.

Repertorium returns sources, not legal advice. The model writes the answer; the legal assessment stays with you.
