The trial judge had the evidence of 2 experts to assist her. She preferred the evidence of the defendants' expert, Mr. Leggett.
The Honourable Mr. Justice Macfarlane, Court of Appeal for British Columbia, CA V02833.

... These visibility findings are in keeping with the opinion of Mr. Leggett, the expert tendered by the defendant. Because I preferred his opinion over the opinion of Mr. X (who was the expert tendered by the plaintiff), where Mr. X's opinion differed with the opinion of Mr. Leggett , I accept Mr. Leggett's  opinion.  
Reasons for Judgement of the Honourable Madam Justice Sinclair Prowse, Supreme Court of British Columbia, No. B931652.
