"Decisions taken pursuant to the lawful operation of immigration control will be proportionate in all save a small minority of exceptional cases, identifiable only on a case by case basis."
"For the reasons given by your Lordships in the appeals of R (Ullah) v Special Adjudicator and Do v Secretary of State for the Home Department[2004] UKHL 26 , it must now be accepted that in principle article 8 could exceptionally be engaged by the foreseeable consequences for health of removal from the United Kingdom pursuant to an immigration decision, even though they do not amount to a violation of article 3. In order to bring himself within such an exceptional engagement of article 3 the applicant has to establish a very grave state of affairs, amounting to a flagrant or fundamental breach of the article, which in effect constitutes a complete denial of his rights. It is necessary accordingly to consider the present case in order to determine whether an adjudicator could arguable find that the removal decision is a breach of article 8."
