Along with Eliot Morley and Jim Devine, Mr Chaytor argued that only Parliament could deal with the matter. This argument was based on either the Bill of Rights 1689 or on an "exclusive jurisdiction" of Parliament but this was rejected by the Supreme Court. The Court of Appeal (Criminal Division) had also rejected the Bill of Rights argument. Mr Chaytor pleaded guilty after the Supreme Court delivered judgment.

Addendum 8th January: Mark Leech (Editor of ConVerse) wrote in The Guardian - "What can David Chaytor expect now that he has been sentenced?" Leech describes the process of admission to prison but concludes his article with this comment - "He should keep a diary from day one – if other 'dishonourable members' are any example to follow, there is money to be made once the darkest days are over."
