The appellants, pig farmers, purchased gilts and boars from the respondent.
The animals arrived sick and infected the appellants' herd.
The trial judge found the respondent breached the implied warranty of fitness under the Sale of Goods Act but dismissed the appellants' counterclaim for damages, finding they failed to prove their loss.
The trial judge relied on CAIS records rather than the PigCHAMP records used by all experts.
The Court of Appeal held the trial judge erred in his assessment of damages by relying on records without explanatory evidence and failing to resolve differences in the experts' assumptions.
The Court also found the trial judge erred by failing to determine the number of free replacement animals promised.
A new trial was ordered on the issues of damages and the balance owing.
