Whether a statutory decision has been made under a provision like s 61(2) of the Public Service Act 1922 (Cth) involves inquiry into the decision-maker's state of mind, and the decision-maker's evidence as to whether they reached a conclusion is admissible. A purely objective test is not required. Deliberate concealment under s 33(1)(b) of the Limitation Act 1985 (ACT) requires proof not only that a relevant fact was concealed but that the respondent intended to conceal it, which ordinarily requires evidence of motivation to conceal.
