Sheppard J in Colgate at 233:
In consequence of the settled practice which exists, the Court ought not usually make an order for the payment of costs on some basis other than the party and party basis. The circumstances of the case must be such as to warrant the Court in departing from the usual course. That has been the view of all judges dealing with applications for payment of costs on the indemnity or some other basis whether her or in England. The tests have been variously put. The Court of Appeal in Andrews v Barnes … at 141 said the Court had a general and discretionary power to award costs as between solicitor and client "as and when the justice of the case might so require". Woodward J in Fountain Selected Meats appears to have adopted what was said by Brandon LJ (as he was) in Preston v Preston … at 637; namely, there should be some special or unusual feature in the case to justify the Court in departing from the ordinary practice. Most judges dealing with the problem have resolved the particular case before them by dealing with the circumstances of that case and finding in it the presence or absence of factors which would be capable, if they existed, or warranting a departure from the usual rule. But as French J said (atp8) in Tetijo, "The categories in which the discretion may be exercised are not closed". Davies J expressed (at p6) similar views in Ragata …

Later cases have emphasised that the discretion to depart from the usual "party and party" basis for costs is not confined to the situation of what Gummow J described as the "ethically or morally delinquent party" (Botany Municipal Council v Secretary, Department of the Arts, Sport, the Environment, Tourism and Territories (1992) 34 FCR 412 at 415): see Baltic Shipping Co v Dillon, "Mikhail Lermontov" (1991) 22 NSWLR 1 at 34; Colgate-Palmolive Co v Cussons Pty Ltd (1993) 46 FCR 225 at 233-234. Nevertheless the court requires some evidence of unreasonable conduct, albeit that it need not rise as high as vexation. This is because party and party costs remain the norm, although it is common knowledge that they provide an inadequate indemnity. Any shift to a general or common rule that indemnity costs should be the order of the day is a matter for the legislature or the rule-maker: Huntsman Chemical Co Australia Ltd v International Pools Australia Ltd (1995) 36 NSWLR 242 at 248.
(a) No chance of success
36 I held in Westfield No 1 at [27] that the Applicants' case was not manifestly hopeless if it could be properly pleaded. I held at [19] that there had been a failure to plead at all the case on which the Applicants opened.
37 On one view it is too early in the procedings to resolve whether this case has any prospects of success. There has been no final resolution of the proceedings here as they have been dismissed. Further, my conclusion in each of the strike out applications was that there was no arguable case articulated, not that there were no reasonable prospects of success.
