filter_casesStructured filtering of court cases using the database. Unlike search_cases (which uses full-text search), this tool filters cases using exact database fields. Returns case metadata without full content, newest first, with ``total`` and ``has_more``. If an exact count takes too…
get_caseRetrieve a court case by ID or slug. By default returns the case metadata and the complete, untruncated ``content`` as plain text (HTML tags removed, entities decoded, whitespace normalized; one line per paragraph, Randnummern as line prefix). To read a long decision piece by pi…
get_case_statisticsGet aggregated case statistics. Returns case counts grouped by time period, optionally filtered by court, state, or jurisdiction. Without ``date_after`` only the **last 12 months** are counted. For counts over a longer period ("per year since 2018"), pass ``date_after`` (e.g. "2…
get_similar_casesFind court cases textually similar to a given case. Seeds an Elasticsearch "more like this" query with the full text of the given case and returns the most similar OTHER cases, ranked by similarity. Useful for comparative research: once you have one on-point decision, surface ne…
search_casesFull-text search for German court cases via Elasticsearch. Returns matching cases (with ``file_number``) and highlighted snippets. Does NOT return full case text - use get_case to retrieve complete content. The citation filters compose with ``query`` so you can answer "cases cit…

get_cases_for_lawFind all cases that cite a specific law section. Returns cases that reference the given statute section in their text. Useful for understanding how courts interpret a specific provision. To narrow the citing set by keyword, court, or date, use ``search_cases(query=..., cited_law…
get_citing_casesGet reverse references TO a case (cases that cite this case). Find all cases that reference the given case in their text. Useful for understanding the impact and precedent value of a decision. To narrow the citing set by keyword, court, or date, use ``search_cases(query=..., cit…

search_legalSearch BOTH legislation and court cases in one call. Returns the most relevant law sections AND court decisions for the query, **grouped by type**. Use this when a legal question may be answered by statute or by case law and you don't yet know which — e.g. "ortsübliche Vergleich…
