"(i) In commercial litigation where each party has claims and asserts that a balance is owing in its own favour, the party which ends up receiving payment should generally be characterised as the overall winner of the entire action. (ii) In considering how to exercise its discretion the court should take as its starting point the general rule that the successful party is entitled to an order for costs. (iii) The judge must then consider what departures are required from that starting point, having regard to all the circumstances of the case. (iv) Where the circumstances of the case require an issuebased costs order, that is what the judge should make. However. the judge should hesitate before doing so, because of the practical difficulties which this causes and because of the steer given by Rule 44.3(7). (v) In many cases the judge can and should reflect the relative success of the parties on different issues by making a proportionate costs order. (vi) In considering the circumstances of the case the judge will have regard not only to any Patt 36 offers made but also to each party's approach to negotiations (insofar as admissible) and general conduct of the litigation. (vii) If (a) one party makes an order offer under Part 36 or an admissible offer within Rule 44.3(4)(c) which is nearly but not quite sufficient, and (b) the other party rejects that offer outright without any attempt to negotiate. then it might be appropriate to penalise the second party in costs. (viii) 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 A2LE0ved .ludument 81. costs specific to the issues which he has won but also the common costs."
