“In numerous cases the Court of Appeal has stressed that the courts should be ready to make proportionate (or percentage) costs orders which reflect, not merely the overall outcome of the proceedings, but also the loss on particular issues. In Multiplex Constructions (UK) Ltd v Cleveland Bridge UK Ltd[2008] EWHC 2280 (TCC) ; 122 Con. L.R. 88, a case where many claims and counterclaims were brought (some of which succeeded and some of which failed) Jackson J, after reviewing the authorities on r.44.2 generally as they then stood, extracted from them eight “principles” ([72(i)] to [72(viii)]), including two principles relevant to proportionate costs orders, in particular (1) that in many cases the judge can and should reflect the relative success of the parties on different issues by making a proportionate costs order ([72(v)]), and (2) that in assessing a proportionate costs order the judge should consider what costs are referable to each issue and what costs are common to several issues; it will often be reasonable for the overall winner to recover not only the costs specific to the issues which he has won but also the common costs ([72(viii)]). …In Grupo Hotelero Urvasco SA v Carey Value Added SL[2013] EWHC 1732 (Comm) ; [2013] 5 Costs L.R. 669 (Blair J), a complex case where the losing claimant succeeded on three important issues, the trial judge concluded that the costs order should reflect, in a substantial way, the defendant’s failure to make good a particular argument, and, at least to an extent, the outcome of two other issues, and ordered that the defendant’s costs should be reduced by 25%.”
