Counsel for the respondents pointed out that the expression "notice has not been given" was used in the proviso in contrast to the expressions "levied" and "service of" which were used in par (b) of s 139(2). He also pointed out that actual receipt of a notice was not necessary for there to be service under s 628. Reasoning from these premises, he contended that the proviso was directed to those cases where, although a rate notice had been served by delivering the notice to another person [4] or by posting [5] or affixing it, [6] the addressee had not received the notice within the year for which the rate was made, that is to say, where there had been no "service in fact" within that year. The purpose of the proviso, he said, was simply to declare that, in cases of deemed service, liability was not affected " by reason only of the fact that notice has not been given to such person within the year for which the rate is made" (our italics). On this construction, therefore, the proviso to s 139(2) had nothing to say concerning the time when a rate must be levied. It merely preserved a liability otherwise imposed. If, for some reason other than lack of notice, no liability was imposed, the proviso did not conflict with any enactment that provided that reason. Consequently, cl 24(2), in directing that a rate must be levied during the year for which it was made, did not conflict with s 139(2).
