16 Here ICL's right to costs and the plaintiffs' liability therefor, did not vest or accrue at the earliest until judgment was given on 5 May 1998. There is I think a respectable argument that it is impossible to speak of the existence of a right or liability affected by the operation or repeal of r 16 until the amount of costs awarded is quantified, in this case by the process of taxation when, for the first time, it can be seen whether the award made would be governed by the limit prescribed by r 16 if operative. The mere institution of the proceedings could not, in my opinion, of itself be regarded as vesting in the plaintiffs the right not to be subjected to costs greater than a particular amount if they were ultimately to lose their action. It is sufficient for present purposes that I conclude that at the time of the repeal of r 16, whenever that was, it was not the case that, contrary to the Interpretation Act 1984 s 37(1)(c) the repeal affected without the contrary intention appearing "any right, interest, title, power or privilege created, acquired, accrued, established or exercisable or any status or capacity existing prior to the repeal".
