As to the underlying case it depends in part on how frail the pensioners are as to whether this is or is not an appropriate action to take. I was contacted recently by someone representing a group of people who have left the country to get away from the biased procedures (Lashin v Russia) that operate in England and Wales. I hope to see this reported in some way (even if it is only on my web log) in the future.
I am not sure myself whether this will produce the result that the system is trying to get. However, it is only when there is a pattern of such cases that it becomes possible to judge independently what works and what doesn't. (Notwithstanding the issue as to whether this is proportionate).
