Judges quite often keep defendants, who have been on bail until the trial, in custody during the trial or for key parts of it. A defendants will turn up for the trial, see how it's going, see that one witness has proved too good against him (contrary to expectations, when the defendant thought the witness had been squared !) and then decide to disappear.There's no profit in failing to attend the trial, that counts against you straight off next time and ensures custody when your captured, but during it might be your best hope.
Ah well. This judge can be wise after the event. Still, if he's convicted, this defendant will know in advance what he's facing on recapture.There's no reason for the trial not to go on, he having gone of his own free will. The House of Lords has ruled for the possibility of the absent defendant being represented nonetheless and his giving instructions to his lawyers.This presents the amusing possibility of Blake sending instructions during the trial via text or phone from some secret location (but may not be quite what their Lordships had in mind !)
