Hi Bridget. I doubt JB'S team would submit the details to the CCRC if it was not valid and he still waiting for their reply since 2004. According to the above.

"Jeremy’s legal team made his current submission to the CCRC in 2004: he is still awaiting a decision! "
Hi Patti,,,the McCanns asked for a test and were refused by the PJ's,,remember.?
I would go as far as to say that those who ask for a test,are the innocent ones and are willing to go all out to prove their innocence.
Perhaps they should be in use more in this country to avoid MOJ's. After all,I can't see those who are guilty,volunteering to take one.
