The transitional provisions with respect to humanitarian and compassionate considerations provide that the bar on access to an application on humanitarian and compassionate grounds after a refugee protection division decision does not apply during the period between the royal assent and the coming into force of the provisions with respect to the refugee appeal division. So that provides an opportunity for mitigation when a person is rejected by the refugee protection division and does not yet have access to the refugee appeal division.
