Ris tools 13
ris_bundesrechtSearch Austrian federal laws (Bundesrecht). Use this tool to find Austrian federal legislation like ABGB, StGB, UGB, etc. Search strategy: "titel" and "paragraph" are the precise entry points — prefer them whenever the law or the section is known ("paragraph" is ignored for applikation="Erv", the English translations). "suchworte" runs a broad full-text search and the RIS API returns those hits ordered alphabetically by law title, not by relevance, so a common term buries the relevant law under thousands of results. Austrian law often splits one topic across several statutes, so look for a companion law: warranty, for example, is covered both by the VGG (consumer sales, B2C, in force since 2022) and by §§ 922 ff ABGB (general warranty law, including B2B). Example queries: - suchworte="Mietrecht" -> Find laws mentioning rent law - titel="ABGB", paragraph="1295" -> Find specific ABGB section - titel="B-VG", paragraph="7", abschnitt_typ="Artikel" -> Article-based laws - titel="ABGB", fassung_vom="2015-01-01" -> Consolidated version as of a date - applikation="Begut" -> Search draft legislationris_landesrechtSearch Austrian state/provincial laws (Landesrecht). Use this tool to find laws enacted by Austrian federal states (Bundeslaender). Search strategy: "titel" and "paragraph" (together with "bundesland") are the precise entry points — prefer them whenever the law or the section is known. "suchworte" runs a broad full-text search and the RIS API returns those hits ordered alphabetically by law title, not by relevance, so a common term buries the relevant law under thousands of results. Austrian law often splits one topic across several statutes and across the federal/state divide — when the topic turns out to be federal rather than state law (warranty, for example, sits in the VGG and in §§ 922 ff ABGB), search it with ris_bundesrecht instead. Example queries: - suchworte="Bauordnung", bundesland="Salzburg" -> Find state building law - titel="Bauordnung", bundesland="Wien", paragraph="1" -> Specific section - suchworte="Naturschutz", bundesland="Tirol", fassung_vom="2020-01-01" -> Version as of a dateris_judikaturSearch Austrian court decisions (Judikatur). Use this tool to find court decisions from Austrian courts. Choose the jurisdiction via "gerichtsbarkeit" (which court system to search). RIS distinguishes two document kinds, controlled by "dokumenttyp": - Rechtssatz: abstract legal principle / headnote (Leitsatz) distilled from a decision - Entscheidungstext: the full decision text including reasoning (Begruendung) The default "beide" searches both for the most complete results. Example queries: - gerichtsbarkeit="Vfgh", suchworte="Grundrecht" -> Constitutional Court decisions - suchworte="Schadenersatz", gericht="OGH" -> Only Supreme Court (OGH) decisions - norm="1295 ABGB" -> Which decisions cite §1295 ABGB? - gerichtsbarkeit="Justiz", fachgebiet="Arbeitsrecht", sortierung="datum_ab" -> Newest labor-law decisionsris_bundesgesetzblattSearch Austrian Federal Law Gazettes (Bundesgesetzblatt). Use this tool for historical research and tracking when laws were enacted. Contains official publications of federal laws, ordinances, and treaties. Example queries: - bgblnummer="120", jahrgang="2023", teil="1" -> Find specific gazette - suchworte="Klimaschutz" -> Full-text search in gazettesris_landesgesetzblattSearch Austrian State Law Gazettes (Landesgesetzblatt). Use this tool to find official publications of state/provincial laws. Covers all 9 federal states (Bundeslaender). Example queries: - lgblnummer="50", jahrgang="2023", bundesland="Wien" - suchworte="Bauordnung", bundesland="Salzburg"ris_regierungsvorlagenSearch Austrian Government Bills (Regierungsvorlagen). Use this tool for legislative history and parliamentary materials. Contains government proposals submitted to parliament. Example queries: - suchworte="Klimaschutz" -> Full-text search in bills - einbringende_stelle="BMF (Bundesministerium für Finanzen)" -> Bills from Finance Ministry - beschlussdatum_von="2024-01-01", beschlussdatum_bis="2024-12-31" -> Bills from 2024ris_dokumentRetrieve full text of a legal document. Use this after searching to load the complete text of a specific law or decision. Note: For long documents, content may be truncated. Use specific searches to narrow down.ris_dokument_abschnittReturn one section of a document already open in the RIS document viewer. Intended for the viewer widget, not for direct use — for the full text of a document use `ris_dokument`.ris_bezirkeSearch Austrian district administrative authority announcements (Kundmachungen der Bezirksverwaltungsbehörden).
