[53] It is, therefore, strictly unnecessary to deal with the appellant's argument that s 106 of the Act, in combination with s 12(1)(a), has the effect that the officers of the Department acted lawfully in taking the respondent's age into account in formulating the program offered to the complainant at the beginning of 2004. It may be said, however, that the learned primary judge was clearly correct in upholding the contention advanced on behalf of the appellant in that regard in relation to the Department's decisions at the beginning of 2004. It is, with respect, difficult to see how it could be held that the officers of the Department were not acting lawfully in taking the respondent's age into account in making a decision in mid-2004 not to revise the decision made earlier. In both cases, the officers of the Department were expressly authorised, and, indeed, obliged by s 12(1)(a) of the Education Act, to take the respondent's age into account in their decision making. They could not be guilty of unlawful discrimination by acting on a footing required by the Education Act. In my respectful opinion, to the extent that the learned primary judge seems to have thought otherwise, his Honour was in error.
