“(4) In deciding what order (if any) to make about costs, the court must have regard to all the circumstances, including – (a) the conduct of all the parties; (b) whether a party has succeeded on part of his case, even if he has not been wholly successful; and (c) any payment into court or admissible offer to settle made by a party which is drawn to the court’s attention and which is not an offer to which costs consequences under Part 36 apply. (5) The conduct of the parties includes – (a) conduct before as well as during the proceedings….. (b) whether it was reasonable for a party to raise, pursue or contest a particular allegation or issue; (c) the manner in which a party has pursed or defended his case or a particular allegation or issue; (d) whether a claimant who has succeeded in his claim, either in whole or in part, exaggerated his claim” (a) the conduct of all the parties; (b) whether a party has succeeded on part of his case, even if he has not been wholly successful; and (c) any payment into court or admissible offer to settle made by a party which is drawn to the court’s attention and which is not an offer to which costs consequences under Part 36 apply. (a) conduct before as well as during the proceedings….. (b) whether it was reasonable for a party to raise, pursue or contest a particular allegation or issue; (c) the manner in which a party has pursed or defended his case or a particular allegation or issue; (d) whether a claimant who has succeeded in his claim, either in whole or in part, exaggerated his claim”
“(6) The orders which the court may make under this Rule include an order that a party must pay – (a) a proportion of another party’s costs; (b) a stated amount in respect of another party’s costs; (c) costs from or until a certain date only; (d) costs incurred before proceedings have begun; (e) costs relating to particular steps taken in the proceedings; (f) costs relating only to a distinct part of the proceedings; and (g) interest on costs on or until a certain date, including a date before judgment.” (a) a proportion of another party’s costs; (b) a stated amount in respect of another party’s costs; (c) costs from or until a certain date only; (d) costs incurred before proceedings have begun; (e) costs relating to particular steps taken in the proceedings; (f) costs relating only to a distinct part of the proceedings; and (g) interest on costs on or until a certain date, including a date before judgment.”
“(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 issue-based costs order, that is what the judge should make. However, the judge should hesitate before doing so, because of the practical difficulties 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 the 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 Part 36 offers made but also to each party’s approach to negotiations (insofar as admissible) and general conduct of the litigation. (vii) …….. (viii) In assessing a proportionate costs order the judge should consider what costs are referable to which 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.”
