In The Secretary of State for the Home Department v SU [2017] EWCA Civ 1069 (20 July 2017), the Court of Appeal clarified from the outset that they had been informed that the appeal before them was the first occasion on which they were concerned with the correct approach to the revocation of a deportation order where it had been implemented but the deportee had, in breach of the deportation order, returned to the UK and established a private and family life following the period of unlawful presence.
