The Canada Federal Court Judicial Review is the proper legal process when your application has been refused and it has no statutory right of appeal before the Immigration Appeal Division (IAD) of the Immigration and Refugee Board (IRB).
Refusal and Decision rendered by the Immigration Appeal Division can only be appealed through judicial review before the Federal Court. On the other hand, refused Inland spousal sponsorship applications as well as economic class permanent resident applications can be appealed before the Canada Federal Court Judicial Review.
The Canada Federal Court for Judicial Review has a discretionary power on whether or not it will hear a particular case submitted before it. An appellant may first request for a leave of court to commence the judicial review of his/her case, but this is subject to the sound discretion of the tribunal. Hence, the appellant’s appeal is merely a privilege and not a right.
