“Unless the court orders otherwise, a claimant who discontinues is liable for the costs which a defendant against whom the claimant discontinues incurred on or before the date on which notice of discontinuance was served on the defendant.”
“(1) when a claimant discontinues the proceedings, there is a presumption by reason ofCPR 38.6 that the defendant should recover his costs; the burden is on the claimant to show a good reason for departing from that position; (2) the fact that the claimant would or might well have succeeded at trial is not itself a sufficient reason for doing so; (3) however, if it is plain that the claim would have failed, that is an additional factor in favour of applying the presumption; (4) the mere fact that the claimant's decision to discontinue may have been motivated by practical, pragmatic or financial reasons as opposed to a lack of confidence in the merits of the case will not suffice to displace the presumption; (5) if the claimant is to succeed in displacing the presumption he will usually need to show a change of circumstances to which he has not himself contributed; (6) however, no change in circumstances is likely to suffice unless it has been brought about by some form of unreasonable conduct on the part of the defendant which in all the circumstances provides a good reason for departing from the rule.”
“a claimant who seeks to persuade the court to depart from the default rule must provide cogent reasons and is unlikely to be able to satisfy the court that there is good reason to do so save in unusual circumstances.”
“It is also important to step back and look at this case, and the default rule, in the round. The presumption in rule 38.6 arises because, in the ordinary case, the discontinuance of a claim by a claimant against a defendant will usually amount to an admission or an acceptance that the proceedings should never have been commenced. In such a case, the starting point must be that the defendant is entitled to its costs, and that is reflected in the default rule.”
