About this work
What can the Federal Court actually order?
If the application succeeds, the court sets the decision aside and sends the matter back to be decided again by a different officer. That is the usual remedy, and it is worth being clear about what it is.
The court does not grant you a visa, a permit or permanent residence. It cannot substitute its own view for the officer's. Anyone who tells you a judicial review will get you status is describing a power the court does not have.
What a redetermination gives you is a decision made properly, on a record the court has said was mishandled. In practice that is often enough to change the outcome, but the second decision belongs to the officer.
