“30. Another issue […] is concerned with the circumstances in which it is appropriate to order one defendant, against whom the claimant has succeeded, to pay the costs of another defendant, against whom the claimant has failed and, in particular, the circumstances in which it is appropriate to order the unsuccessful defendant to pay the successful defendant's costs directly as opposed to those cases where it is appropriate to order the claimant to pay them leaving the claimant to recover them (if he can) from the unsuccessful defendant, so that, in effect, the unsuccessful defendant pays the successful defendant's costs but does so indirectly as part of the claimant's costs of the action. There was once much learning on the topic and the forms of order to which it gave rise were known as Sanderson (in the case of direct) and Bullock (in the case of indirect) orders. (See Sanderson v Blyth Theatre Company[1903] 2KB 533 and Bullock v London General Omnibus Co.[1907] 1 KB 264 ) As Mr Moody-Stuart explained, the jurisdiction to make such orders survived the advent of the CPR, being permitted under Part 44.3, and was discussed in Irvine v Commissioner of Police for the Metropolis[2005] EWCA Civ 129 at [22] to [31]. I think it is sufficient only to refer to what was said in Moon v Garrett[2006] EWCA Civ 1121 by Waller LJ who, after considering the authorities including Irvine, summarised the jurisdiction as follows (at [38] and [39]): “38. It seems to me that the above citation demonstrates that there are no hard and fast rules as to when it is appropriate to make a Bullock or Sanderson order. The court takes into account the fact that, if a claimant has behaved reasonably in suing two defendants, it will be harsh if he ends up paying the costs of the defendant against whom he has not succeeded. Equally, if it was not reasonable to join one defendant because the cause of action was practically unsustainable, it would be unjust to make a codefendant pay those defendant's costs. Those costs should be paid by a claimant. It will always be a factor whether one defendant has sought to blame another. “38.

The fact that cases are in the alternative so far as they are made against two defendants will be material, but the fact that claims were not truly alternative does not mean that the court does not have the power to order one defendant to pay the costs of another. The question of who should pay whose costs is peculiarly one for the discretion of the trial judge. ”
