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 Part 5 - reviewable decision (see subsections 338(1) and 348(2)).
