Costs – Orders for costs. When a solicitor signed a bill of costs, he certified that the contents of the bill were correct, and the court and receiving party were entitled to rely upon that certificate; unless there were circumstances such as to raise suspicion, the paying party could not go behind the certificate. As the first respondent solicitor had certified an inaccurate bill and made a misrepresentation, the Court of Appeal, Civil Division, made an order under CPR 44.11, reducing the costs recoverable by the first respondent by disallowing half the profit costs of the bill.
