What happened
Attorneys submitted court filings containing references to cases that did not exist. The fabricated citations were properly formatted, carried plausible case names and reporter numbers, and read as established precedent. An AI assistant had generated them, and they were accepted without verification.
Impact
Judicial sanctions, professional discipline, public embarrassment, and a measurable erosion of trust in the use of AI in legal practice.
WEKID™ insight
A Data-layer integrity gate blocks outputs containing unverifiable citations before they reach a filing, via citation enforcement and source verification, measured by fabricated-citation count and claim-verification rate. The deeper failure is at Wisdom: confident output in a high-stakes domain was trusted on fluency alone. Because fabrication is detected, the Fabrication Gate caps the score and routes the output to Rejected.
