The Minister may issue a conclusive certificate in relation to a decision if the Minister believes that:
(a) it would be contrary to the national interest to change the decision; or
(b) it would be contrary to the national interest for the decision to be reviewed.
Note: If the Minister issues a conclusive certificate in relation to a decision, the decision is not a reviewable migration decision (see paragraph 338(1)(a)) or a reviewable protection decision (see paragraph 338A(2)(a)).
