This is not new at all. Several countries have designated lists. We also have to remember that a designated list does not remain static. There are changes that take place.
There have to be the types of mechanisms and safeguards that are necessary to ensure that nothing has changed in the country between the time the determination takes place and the time the person is removed. There has to be a mechanism in place to track these things. It cannot be an absolute decision where you have x number of countries and anyone from those countries will be dealt with differently.
