Keith - you took those words out of context, and removed some very significant qualifying words from the abbreviated sentence you gave.

Here is the post I made:
If someone has demonstrated that they were legally in this country at one point, and they have no passport, how can it be relevant or reasonable to require that they have been here continuously since that date?

Making those kinds of demands of proof, and denying someone's right to stay on the basis that they cannot produce documentary evidence is clearly unreasonable and abusive harassment.

I was talking about where unrealistic demands for specific bits of evidence are demanded, and other kinds of evidence, however compelling, are excluded. Read the case histories which are readily available, and see if you can reconcile them with honourable behaviour on the part of those responsible. And
