Get Case Citation Network
citations_networkRead-onlyIdempotent
Extract and group all OSCOLA citations from a judgment XML by type, deduplicated and sorted, for authority-network analysis.
Instructions
USE THIS TOOL WHEN you have a judgment slug and want to map every citation it makes — cases cited, legislation referenced, SIs, retained EU law.
Fetches the judgment XML from TNA and parses all OSCOLA citations within. Returns citations grouped by type, deduplicated and sorted. AFTER calling, pass any individual citation through citations_resolve to confirm it resolves and to retrieve its canonical URL.
Useful for authority-network analysis (what did this judgment rely on?) and for surfacing the legislative landscape a case sits inside.
