Anonymous v. Anonymous
Israel · Apr 29, 2025
What happened in this matter?
The court dismissed the petition in limine and imposed personal costs on the plaintiff's counsel, totaling ₪5,000, for submitting fabricated legal citations generated by AI. The judge ruled that counsel failed in their professional duty to verify the accuracy and existence of authorities cited in pleadings, regardless of whether the submission was intentional or negligent.
- Why the court cared
- The judge found that legal pleadings are the “foundational documents of judicial proceedings” and must be “accurate, reliable, and competently drafted.” Submitting fictitious judgments constitutes not only a procedural abuse but an ethical breach. Even absent bad faith, failure to verify AI-generated legal content breaches a lawyer’s core obligations
- Why it matters now
- Misnumbering is not a credible defense when citations do not exist anywhere—personal costs follow denial.
Why this matter is tracked
Fabricated: Case Law | Plaintiff's counsel cited several Family Court decisions in the complaint that do not exist; the court could not locate them in legal databases and accepted they were AI-generated. Outcome: Petition dismissed in limine; Plaintiff’s counsel ordered to pay ₪1,500 in personal costs to the state and ₪3,500 to the opposing party.
AI Use
The plaintiff’s attorney denied deliberate use of generative AI, claiming the wrong file numbers were inserted by mistake. The court rejected this explanation, finding the hallucinated decisions did not exist in any legal archive and could not plausibly arise from mere misnumbering. The court accepted the defendant’s assertion that the fabricated citations originated from generative AI.
Hallucination Details
Out of five rulings cited in the petition, three were not found in any legal database. Two additional cases were filed after the hearing, but neither matched the original citations or contained the propositions advanced in the pleading. The court found the overall drafting pattern aligned with generative AI hallucination phenomena.
Ruling/Sanction
Judge Merav Eliyahu dismissed the petition and imposed personal costs of ₪1,500 against Plaintiff’s counsel (payable to the state) and ₪3,500 (payable to the opposing party). She cited Supreme Court precedent and ethical commentary emphasizing the risks of hallucinated legal drafting. She emphasized that lawyers must not rely blindly on AI tools and must always verify the authenticity of legal authorities cited in pleadings.
Key Judicial Reasoning
The judge found that legal pleadings are the “foundational documents of judicial proceedings” and must be “accurate, reliable, and competently drafted.” Submitting fictitious judgments constitutes not only a procedural abuse but an ethical breach. Even absent bad faith, failure to verify AI-generated legal content breaches a lawyer’s core obligations.
Misnumbering is not a credible defense when citations do not exist anywhere—personal costs follow denial.
