Answer.

Evidence / professional-responsibility rule · AI Citation Sanctions.

Yes — courts have sanctioned lawyers under Rule 11 (and the bankruptcy analogue Rule 9011) and inherent authority for filing briefs containing AI-fabricated citations, treating it as a failure of the duty of candor and the obligation to verify filings. The sanction wave is real and growing. Planisphere does not validate case citations; the safeguard is human verification of every authority before filing, and the firm remains responsible.

When AI Citation Sanctions asks for proof, hand over records — not assurances.

record the duty · seal the receipt · verify offline

Planisphere records each duty event — an output marked, a disclosure shown, a review made — and seals it into a receipt that verifies offline against our published keys. You send hashes, never content. A record is evidence a third party can check; it is not a certification and not a legal determination.
