I found something interesting here:
http://freemovement.wordpress.com/2007/12/
A very well sourced rumour has it that 95% of the outstanding 450,000 asylum ‘legacy’ cases so far resolved have resulted in grants of status.
I think the 16000 removals were cases of asylum seekers who have never received a questionnaire and were picked up for removal. It says that all asylum cases prior to 5th march 2007 are legacy cases but it does not mean that everybody will be considered under the case resolution programme.
ILPA Document:
However, the BIA have now informed us that some people may never receive a questionnaire
even though their case is within the legacy backlog. Some people in this backlog may never have
their case considered by the Case Resolution Directorate, which is the part of the BIA that is
responsible for dealing with the backlog.
The CRP started on 1st November 2006 and until today 16000 asylum seeker have been removed.
Somebody correct me if I'm wrong somewhere.
