"In the course of enquiries, the level of information available to officers changes – perhaps through interview, further interview, or representations from legal representatives and other bodies, etc. Officers should bear in mind that they have a continuing discretion as to whether to maintain or withdraw the notice of illegal entry. If as a result of information obtained at a later stage or as a result of a change of circumstances, it becomes apparent that an individual is being prejudiced as a result of the notice of illegal entry and that it is unfair on them to maintain it, then the notice should be withdrawn."
