"I've checked my notebook and confirm I did deal with Robinson and HMP Hewell on1st May 2015 , sitting as an independent adjudicator, for escape and sentenced him to 14 added days to his sentence. It was an internal disciplinary hearing. I would not have dealt with the case had I known it was to be or had been referred to the police."
"2.19. Where the charge is escape or abscond the adjudicator will confirm whether the prisoner is being, or has already been, prosecuted for the same offence. If so, it would be double jeopardy to continue with the adjudication for that charge."

"44. The Court went on to adopt the distinction drawn by the House of Lords in Re McC (A Minor)[1985] AC 528 between custody decisions which are, on the one hand, voidable because they are wrong in law by reason of errors within jurisdiction and, on the other hand, those which are void ab initio and ex facie because they are so wrong in law as to be outside or in excess of jurisdiction. These were summarised in Benham in this way (at [25]): 'In its judgment [i.e. that of the House of Lords], a magistrates court acted in excess of jurisdiction in three circumstances only: (1) if it acted without having jurisdiction over the cause; (2) if it exercised its powers in a procedural manner that involved a gross and obvious irregularity, or (3) if it made an order that had no proper foundation in law because of a failure to observe a statutory condition precedent.'"
