" ... previous criminal convictions are relevant only in so far as the circumstances which gave rise to them are evidence of personal conduct constituting a present threat to the requirements of public policy."
"... measures taken by member states in respect of nationals of other member states must be reasonable and not disproportionate to the gravity of their conduct."
"In so far as it may justify certain restrictions on free movement of persons subject to Community law, recourse by a national authority to the concept of public policy presupposes, in any event, the existence in addition to the perturbation to the social order which any infringement of the law involves, of a genuine and sufficiently serious threat affecting one of the fundamental interests of society."
"These were offences committed first upon a child, pursured for years, and not brought to an end until his daughter went to the police. Mr [B] is a man who, over the years, has done well enough for himself in business and employment. He is not without resource. That will help him in resettlement. He has been in this country for many years, and that must surely be the factor of most weight against deportation. His relationship with his former wife and daughter is destroyed, his home is gone. His parents and brothers are here. He has more relatives in Italy than he was prepared to admit. That he would have to leave his parents when they most need him is a compassionate circumstance. The effect upon them is also relevant... The offences are not the first. They were committed over a long period. What the trial judge said about them is undoubtedly justified. They were very serious indeed. There are exceptional cases in which past conduct itself justified deportation of an EC citizen: Marchon [1993] Imm AR 384. In any event, and whilst we accept that there is little likelihood that the Appellant would ever again sexually assault his daughter, he has shown himself over the years to be a man unable to control his passions or to fully appreciate the blame for his actions. He displays in our view a propensity to act in a manner contrary to public policy."
"In my judgment, it is open to the Secretary of State to decide that some offences are so serious, in the sense that they are sufficiently repugnant to the generally accepted standards of morality, that the continued presence in the community is unacceptable, irrespective of a propensity to commit further offences of a similar character. If that is so, the only question that arises is whether a decision of the Secretary of State and the Immigration Appeal Tribunal can be attacked on the grounds of Wednesbury unreasonableness..."
