There could be a case in which an individual has had their passport revoked, for example, and it's very clear that they need to travel, say, to a family funeral or something like that. There would be a discussion and confirmation that this was the case and about where the individual would be going, but a discussion of whether or not it should be allowed. If it were allowed, then there are various procedural mechanisms that can be used to allow the person to travel on a one-off basis.
