Humanitarian and compassionate consideration and the pre-removal risk evaluation are not responsibilities of the IRB. They are the exclusive responsibility of the CIC. These factors do not have any impact on delays.
There are two types of delays: the one between the time that the asylum seeker arrives and the time when the claim is filed, and the delay between the time when the claim is filed and when it is heard by the IRB.
Humanitarian and compassionate consideration and pre-removal risk assessment have no impact on the delays, because these matters are raised after the IRB has reviewed the claims.
