Look Up Provision by Citation
legal_lookupRetrieve a specific legal provision by citation (e.g. '§ 823 BGB', 'Art. 6 DSGVO', '§ 280 Abs. 1 BGB'), or a court decision by Aktenzeichen or ECLI (e.g. 'VII ZR 184/14', 'BGH VII ZR 184/14', 'C-184/14', 'ECLI:DE:BGH:2017:050117BVIIZR184.14.0'). Citation order is flexible — '§ 9 DSGVO', 'DSGVO Art. 9', 'Artikel 9 DSGVO' all resolve correctly. is_exact_match reports whether the citation was matched exactly; non-exact results can be a semantic fallback, the first section of an annex, or an uncertain decision match. The result hint explains which case applies; found=true alone does not prove citation identity. Provision text is reassembled where available; content_truncated and the result hint identify incomplete text and its continuation. An ambiguous provision returns found=false with stored candidates and citation_forms: complete citations that select each printing, including a source occurrence where required. Select an EUR-Lex article reprint with its quoted complete key, e.g. '"Art. 45 (2)" reg_2013_153'. An unquoted paragraph qualifier does not select a printing. Quote a complete stored document-part key when its title contains article references; the quoted key takes precedence over coordinates within that title. A decision lookup returns its lead section (Leitsatz); further sections are reachable via legal_get_toc or legal_get_context on the returned norm_id. Where an abbreviation names laws of several legal orders and neither the scope nor the cited provision decides, the result is found=false with reason='ambiguous_jurisdiction' and one candidate per law, each with the legal_lookup arguments that resolve exactly it; also_exists_in on a hit lists the other laws the abbreviation names.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| citation | Yes | Full citation string, e.g. '§ 823 BGB' or 'VII ZR 184/14' | |
| language | No | Document language: 'de' (documents in German, of every legal order in the scope) or 'en' (currently EDPB/EDSA data-protection guidance only). Omitted, the account's document language applies ('de' unless the account sets another). DE and EN are separate corpora — a document published in both languages has one entry per language under the same abbreviation. 'en' selects the English corpus regardless of the answer language; 'edsa' is published mostly in English. | |
| source_type | No | Source the cited law or decision must come from: 'gii', 'eurlex', 'eurlex_caselaw', 'rechtsprechung', 'bverfge', 'bverwg', 'bgh', 'bpatg', 'sachsen_rechtsprechung', 'nrw_rechtsprechung', 'bayern_gesetze', 'nrw_gesetze', 'verwaltungsvorschriften', 'edsa', 'dsk' or 'gesetzesmaterialien'. An abbreviation names one law per source, so the source selects exactly one law — also between federal and state law, which 'de' covers together. Omitted, every source answers. Note: 'edsa' is published mostly in English: language='en' covers the full set, the German corpus only the translated documents. | |
| jurisdiction | No | Legal orders the cited law or decision must belong to, one or more: 'de' (all German law — federal AND state), 'eu', 'de_by', 'de_nw', 'de_sn'. A value matches its own family only: 'de' adds no EU law. Omitted, every legal order answers, and where an abbreviation names laws of several (e.g. 'EUV': a German Verordnung and the EU Treaty), the account's legal order decides; jurisdiction_scope names it. Set, nothing outside it answers: a not_found then lists in also_exists_in where the cited law exists. |
