Regina v Quillan and others [2015] EWCA Crim 538; [2015] WLR (D) 144
‘If it was likely that a judge would need to make a ruling on a question of law relating to a criminal trial, it would usually be better to order a preparatory hearing before the start of the trial rather than having to make such a ruling after the jury had been sworn and the trial commenced, when any appeal against such a ruling by the Crown would require an undertaking that the defendant was entitled to be acquitted if the appeal failed.’
WLR Daily, 25th March
