The effect of a Deportation Order is that the person the subject of such an Order must leave the State and remain thereafter out of the State. Deportation Orders are made under the provisions of the Immigration Act, 1999, as amended, following a comprehensive consideration of an individual's case under Section 3 (6) of that Act and under Section 5 of the Refugee Act, 1996 on the prohibition of refoulement. A Deportation Order does not in itself prevent a person who is the subject of such an Order from entering any other EEA country. However, other EU immigration authorities may, depending on their respective immigration rules and procedures, consider the existence of an Irish issued Deportation Order as sufficient grounds to refuse entry to their national territory. It can be expected that this will be especially the case in respect of entry into the United Kingdom in view of the joint commitment of both Ireland and the UK to protect the integrity of the Common Travel Area arrangement.
