The plaintiffs were involved in a motor vehicle accident when a third party swerved to avoid an unidentified driver and collided with their vehicle.
After the limitation period expired, the plaintiffs successfully moved to add the third party as a defendant under rule 5.04(2) of the Rules of Civil Procedure.
The third party appealed.
The Divisional Court allowed the appeal, finding that adding the third party as a defendant would cause significant prejudice due to the 'one percent rule' regarding unidentified motorist coverage, and that the motions judge erred in finding special circumstances.
