Contest each case vigorously?

Back in July the Home Secretary du jour, Alan Johnson, promised regarding the 20 men being held under the declared illegal Control Orders, that the Labour Government would contest each case vigorously. Of course as has so often been the case with this tough-sounding but basically cowardly Labour government, he has backed down. This morning The Times reports that:

"The Home Secretary has released a man regarded as one of Britain’s most dangerous terror suspects from virtual house arrest to avoid disclosing secret evidence against him, The Times has learnt.

The man, known only as AF, has been subject to a controversial “control order” since 2006 because of his alleged links with Islamic terrorists. He has never been charged, however, and the evidence for the allegations has never been heard in a public court.

The control order was revoked last week and the suspect’s electronic tag removed, setting him free in spite of the Government’s claim that he remains a threat."

As the Government claim that AF is a danger to the public and he is only free because that same Labour government refuse to disclose what evidence they have to this effect, then will the relatives of anyone killed as a result of AF's activities (should there be any) have a claim against Alan Johnson and this Labour government?
