Previous value: -"Restrict results to court decisions that verifiably cite this provision (citation-graph filter, e.g. '§ 573 BGB' or 'Art. 6 DSGVO'). Combine with a case-specific query — e.g. query='Eigenbedarfskündigung Härtefall hohes Alter', cited_norm='§ 573 BGB' — to get decisions that both apply the provision AND match the facts of the case. This is the preferred way to find case law for a specific provision and a specific question. Matching is paragraph-level (Abs./Satz/Nr. are ignored). Only court decisions carry citations, so this filter implicitly restricts to case law — no document_kind needed. For the raw citation inventory of a provision (newest first), use legal_find_citing_decisions instead. For an EU directive both the directive article ('Art. 9 Richtlinie 2011/83/EU') and the national transposition norm ('§ 355 BGB') are valid filters: the directive article matches EU case law (EuGH/EuG) and German decisions citing it directly (richtlinienkonforme Auslegung), while the transposition norm matches the larger body of German decisions applying the transposed rule. Prefer the transposition norm for everyday German case law, the directive article for EU-level interpretation; run a plain legal_search first if you do not know the transposition norm. EU regulations (DSGVO, MDR) are cited directly."New value: +"Restrict results to court decisions that verifiably cite this provision (citation-graph filter, e.g. '§ 573 BGB' or 'Art. 6 DSGVO').

Previous value: -"Filter by document class: the three norm subtypes 'statute', 'regulation' and 'directive' form ONE filter class — any of them admits all three, so you cannot (and need not) tell them apart, and an EU regulation or directive is never hidden by a reflexive 'statute'.
