Costs – Assessment. The master had erred in principle and in his calculations when having assessed the increase in the figure in a second costs estimate which it would be reasonable for the claimant to pay. The Queen's Bench Division, in partially allowing the claimant's appeal, also held that the master had erred in having relied upon the fact that the claimant had not included counsel's fees in the conditional fee agreement as a reason for not having made an overarching reduction in counsel's fees, and remitted the detailed assessment of the defendant's profit costs and of counsel's fees.
