Delegations of the administering authority's functions under Part 3 of the Road Transport (General) Act 1999 (ACT) must be made under s 54, not the general delegation power in s 18. Section 242 of the Legislation Act 2001 (ACT) cannot cure the complete absence of a delegation — it only cures defects in or irregularities in relation to an existing delegation. The onus remains on the challenger to establish want of authority, but where the respondent produces a delegation instrument that is shown to be legally defective, the challenger may discharge that onus.
