Internal reconsideration
A public authority may reconsider its own decision where law or policy provides for that. This is administrative decision-making, not a court.
Appeals, reviews and reconsideration
Different forms of challenge have different purposes. They must not be treated as one generic appeal process.
Tribunal appeal
A tribunal may determine an appeal where legislation gives it jurisdiction. The tribunal is independent of the authority whose decision is under challenge.
Court appeal
An appeal from a court or tribunal exists only where the law provides a route and the applicable procedural requirements are met.
Judicial review
Judicial review is a public-law process concerned with the lawfulness of decisions and public action. It is not a general opportunity to substitute the court's view for every administrative decision.
Use the route stated for the decision or case.
Time limits, permission requirements, available grounds and the existence or scope of any appeal right depend on the relevant law and procedure.
