Why this matter warrants attention
The Ontario Labour Relations Board observed that the responding parties used AI to generate submissions containing 'hallucinated' case citations. The Board did not impose a specific sanction for this conduct but directed the parties to Rule 8.5, which requires electronic links or paper copies for all cited authorities to prevent the submission of fabricated cases.
The Board noted that the responding parties' submissions were replete with irrelevant allegations and included 'hallucinated' cases. The Board pointed to Rule 8.5, which was introduced to guard against the mischief caused by AI-generated fabricated cases by requiring parties to provide electronic links or paper copies of all cited authorities.
This case illustrates the application of specific procedural rules (Rule 8.5) designed to mitigate the risk of AI-generated 'hallucinated' citations in administrative tribunals. It highlights that tribunals may address AI-related failures by enforcing strict verification and citation requirements.
