I'd like to clarify that point. When applicants are refused, they're not refused access to their records in ATIP; they're refused their immigration applications. They're seeking the reasons for refusal.
The reason immigration applicants are going to the Federal Court is that the Federal Court offers an end way around the ATIP system. Whereas an ATIP will often take more than 60 days, or more than 90 days, or sometimes up to a year, when you go to the Federal Court and your application for leave is approved, the Federal Court will make an order and will ask IRCC to produce that record for you. Similarly, when you file a notice of application for leave and judiciary review, automatically the Federal Court will request from IRCC the production of the reasons for refusal.
That is why applicants are going to the Federal Court. In many cases, once they obtain those reasons, they then discontinue the application itself. They're not interested in pursuing the refusal. They're interested in using the court to obtain the reasons for refusal.
