Lord Scott in Chikwamba 
- I have had the advantage of reading in draft the opinion on this appeal prepared by my noble and learned friend Lord Brown of Eaton-under-Heywood and am in complete agreement with the reasons he has given for allowing this appeal. My astonishment that the case should have had to come this far for the, as it seems to me, obvious conclusion that the appellant and her four year old child should be permitted to remain in this country with the appellant's husband and the child's father prompts me to add a few words of my own.
- Not many would dispute, and I do not, that would-be immigrants who desire to remain permanently in this country should apply for permission to do so before coming here. It is the Government's policy that that should be so and that a failed asylum seeker should return, or be returned, to his or her country and make from there any applications for the right to reside in this country that he or she desires to make. But policies that involve people cannot be, and should not be allowed to become, rigid inflexible rules. The bureaucracy of which Kafka wrote cannot be allowed to take root in this country and the courts must see that it does not.
