In a personal injury jury trial arising from a motor vehicle accident, the plaintiff moved before openings to exclude surveillance obtained by the defence after discoveries and disclosed only shortly before trial.
The court held that the defence breached rules 31.09(1)(b) and 30.07 of the Rules of Civil Procedure by failing to promptly notify the plaintiff of post-discovery surveillance and by failing to serve supplementary affidavits of documents.
Applying the leave framework under rule 53.08, the court found the prejudice did not outweigh the probative value because the trial had not yet begun in substance and any prejudice could be addressed by adjournment, costs, and immediate production of the videos.
The defence was granted leave to use the surveillance for impeachment purposes only.
