S and T (Children: Domestic Abuse)

Why this matter warrants attention

Fabricated: Case Law | The father’s AI-generated position statement contained 24 purported case references. The court could not find passages in the cited judgments supporting the propositions, and stated that some references might be hallucinations. Outcome: Both parties’ AI-generated authorities ignored. Both the applicant father and respondent mother used a large language model to generate parts of their written documents. Each included purported case references; the father cited 24 references, and the mother also included numerous AI-generated authorities. The judge found the references entirely worthless, noted that some might be hallucinations, and could not locate passages in the judgments supporting the propositions advanced. The court described the AI-generated case law as misleading and relied instead on the applicable statutes, Practice Directions, and authorities that it could verify. No professional or monetary sanction was imposed specifically for the AI misuse, although the documents were treated as distracting and unhelpful.
