"How was the Circuit? " "Good, but I missed a bugger at Exeter" The legendary interchange between two High Court judges, one of whom had been travelling the country on "Circuit".
The art of potting (summing up to get a conviction) still survives but is less practised than formerly, when some judges prided themselves on their skill at it.The best were very subtle. His Honour Judge "Soapy Joe" (from his ingratiating manner) Grieves was a master. He would tell the jury "Mr Smith, in his spirited defence of this defendant, in the finest traditions of the duty and skill of the English Bar, argued....." at which point you knew your client was doomed!
Summing up for an acquittal is also known but judges are more inclined to take a robust view and stop the case at half time, to direct an acquittal, or to tell the jury that they can themselves decide, without hearing more, that the defendant should be acquitted and to invite them to consider that possibility
