What Is Ministerial Intervention?
Ministerial intervention is a personal, non-compellable power that allows the Minister for Immigration to substitute a more favourable decision in place of a tribunal's review decision, if the Minister considers it to be in the public interest. It is not an appeal, and it is not an extension of the visa application process.
The power exists in two forms. Section 351 of the Migration Act 1958 covers general review decisions made by the Administrative Review Tribunal (and formerly the AAT). Section 501J covers decisions involving character grounds and protection visa cancellations or refusals.
Critically, the Minister is not obliged to consider your request, and even if the request is referred to the Minister, the Minister may still decline to intervene. This is why the quality of your submission and the precision of your eligibility assessment matters enormously.
