Appeals following Judge only trial and convictions are dismissed

Appeals by Twomey, Blake, Hibberd and Cameron have been dismissed by the Court of Appeal (Criminal Division) - judgment here.  In 2004 they were involved in a robbery at Heathrow Airport - (see the previous post on Law and Lawyers) - and on 31st March 2010 they were convicted by a High Court Judge sitting without a jury.  This form of trial is permissible in limited circumstances under the Criminal Justice Act 2003 s.44.  Earlier trials had been abandoned due to jury tampering.  The Lord Chief Justice remarked that when criminals subvert or attempt to subvert the process of trial by jury they have no justified complaint if they are deprived of it.
