The plaintiffs commenced an occupiers' liability action after one plaintiff allegedly struck her head on a staircase in the defendants' building.
At a pre-trial conference, the pre-trial judge ordered the appointment of a court expert to report on liability and human factors, despite objections from the defendants and the plaintiffs' objection to paying the costs.
The pre-trial judge provided no reasons for the order.
The defendants appealed.
The Divisional Court allowed the appeal and set aside the order, holding that the pre-trial judge erred by failing to provide reasons and by issuing an order that required the expert to investigate and weigh evidence, thereby usurping the role of the trier of fact.
