"In these exceptional and unusual circumstances the refusal to grant LR in February 2009 coupled with the grant of only a 3-year LR following his successful appeal and the subsequent refusal to grant him ILR are: (1) a cause of his mental disability; (2) a factor in its development into its current chronic state and (3) a significant if not the sole reason why his essential trauma-focused treatment cannot start. The professional advice of both Dr Ehntholt and Dr Carswell suggests that there is no realistic prospect of trauma focused therapy starting and, if started, of being successfully completed until Y acquires the necessary feelings of security and that has no realistic prospects of occurring unless and until Y is granted ILR."
