You are completely missing the mark here.
The actual problem is that the Home Office is supposed to find illegal immigrants, found the task too hard, and decided that instead it would be a lot easier to find _legal_ immigrants who have problems proving what rights they have. Emphasis on _legal_ immigrants. To the destruction of sailing information: Why assume incompetence, when malice is a perfectly fine explanation?
And these _legal_ immigrants were never asked for any evidence, until more than 45 years later, when that evidence is impossible to get by. 9 years after the government destroyed important evidence - we should fall back to the normal civil court rules; if you destroy evidence then it should be assumed that the evidence was against you.
