REASONS FOR JUDGMENT
THE COURT:
1 The only issue that remains outstanding in this appeal is that of costs. When we handed down our reasons we said that the appropriate order for the costs of the appeal was that Network Ten Pty Limited, the losing party, should pay two thirds of the appellants' costs. Later we invited submissions on the costs of the trial. In its submissions on the trial costs, Ten took the opportunity to take up the question of costs of the appeal.
2 The purpose of costs is as an indemnity to the successful party in litigation. Accordingly the settled practice is that costs follow the event. But the practice is not absolute. In appropriate circumstances the successful party can be deprived of some or all of his costs. He may even be ordered to pay all or part of the costs of the unsuccessful party. The authorities that support these propositions are so well-known they require no citation.
3 The circumstances in which a successful party may be deprived of his costs are too various to be classified, although some of the recognised grounds are mentioned in Ritter v Godfrey [1920] 2 KB 47 at 60-61. Here the factor that motivated us to award the appellants only two thirds of the costs of the appeal (a decision we do not intend to reverse) was that the appellants were not wholly successful in all of their claims, making it both just and appropriate to deprive them of some of their costs. A rough and ready approach resulted in the two thirds costs order. We think that the costs of the trial should be apportioned in the same way, and for the same reason.
