Costs – Estimate of costs. The Queen's Bench Division found that the approach taken by the master when making a costs order that left hourly rates open to be debated on detailed assessment, was inappropriate. The master's approach had been inconsistent with CPR 3.15 and Practice Direction 3E. It provided the parties with no certainty as to what the approved budget was, limited their flexibility when deciding how to spend the budget, and created unnecessary micro-managing. Therefore, the offending parts of the master's order were set aside and any further costs management hearings were dispensed with.
