What, precisely, is the administrative decision in respect of which Glen is entitled to reasons under the ADJR Act?
A decision to reallocate CMTs is not an administrative decision to which the ADJR Act is subject. Someone in CASA deciding to interpret a rule differently than someone else in CASA interprets it is not a decision to which the ADJR Act is subject. Someone in CASA deciding to tell someone they can’t employ Glen is not a decision to which the ADJR Act applies.
Glen has to apply for some certificate or licence or approval that CASA can grant him and be refused it. That’s a decision to which the ADJR Act applies.
