"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."
"So far as it turns on the principle that delay can make disproportionate what was otherwise proportionate, our view is that this would only apply in cases where, as here, that delay was obvious, gross and largely unexplained; and has been allowed to prejudice the interests of children, or others unable to fend for themselves, with close relations settled as of right in this country."
"57. …. It cannot be right that merely because for a relatively small part of the time when an application might have been determined, there was a good prospect or even a likelihood of success, that it follows that any subsequent Determination has to be favourable even if by then the position has changed. If this application had been determined in its first four and a half months, the evidence does not suggest that it would have succeeded. If it had been determined after Bulletin 1/00 was issued again it seems likely to me on the available evidence that it would have failed. Such a situation is in my judgment far removed from the position in Shala and thus even if an argument of this kind had been advanced before the IAT I am satisfied that it would have failed. 58. For these reasons I would dismiss each of these appeals, I consider that there may well be further merit in Mr Wilken's argument that one is not comparing like with like in considering those cases involving a right to remain when there is no existing basis for such a right apart from Article 8 considerations and the underlying circumstances of Shala's case. However, in the light of my conclusions on the factual matters already set out, I find it unnecessary to determine this issue and I consider it better that it awaits to be considered in a case where there are different facts that might otherwise lead to a different conclusion."
