Key legal question
Whether the Federal Court could hear an appeal against the remand decision.
Extracted holding
The remand decision caused irreparable harm for the administration because it bound the office on the good-faith issue and left only hardship to be examined.
Extracted reasoning
A remand decision is ordinarily interlocutory, but a public authority suffers irreparable prejudice when it is forced to issue a decision it considers unlawful and can no longer challenge its own decision later.
