`legal_find_citing_decisions`¶

Reverse lookup: which federal court decisions cite a specific norm? Answers the core legal question "How has BGH interpreted § 280 BGB?" — which legal_search alone can't, because it's ranking-based, not citation-based.

When to use¶

Reviewing judicial interpretation of a norm
Finding case law on a compliance question
Checking whether a norm has ever been treated by a federal court

Parameters¶

Parameter	Type	Default	Description
`cited_norm`	string	—	Citation of the norm (e.g. `§ 823 BGB`, `Art. 6 GDPR`)
`limit`	int	10	Maximum decisions to return (1–100)

Example¶

{
  "tool": "legal_find_citing_decisions",
  "arguments": {
    "cited_norm": "§ 280 BGB",
    "limit": 5
  }
}

Response¶

{
  "count": 5,
  "decisions": [
    {
      "court": "BGH",
      "case_number": "VI ZR 175/22",
      "decision_date": "2023-05-15",
      "title": "Damages for violation of general personality rights",
      "snippet": "The breach of duty under § 280 (1) BGB …",
      "cited_norms": ["§ 280 BGB", "§ 823 BGB", "Art. 2 GG"]
    }
  ]
}

Tips¶

Pair with legal_get_context. Read norm + context first (via legal_search + legal_get_context), then the citing case law — the LLM can then produce a full legal analysis.
