Solicitor – Negligence. The Court of Appeal, Civil Division, allowed the defendant solicitors' firm's appeal and allowed the claimant's cross appeal from an order made after the quantum only trial of a professional negligence claim against the defendant. The judge had made an error of principle in having confined his assessment of loss to the transaction date, rather than the trial date and none of the judge's reasons justified the conclusion that the claimant had not unreasonably failed to mitigate its loss. Nonetheless, the defendant was liable for the full cost which the claimant had incurred in curing a defect in a lease, albeit after trial, in the sum of £157,100.
