A friend recently asked me to cast an eye over a summons she has received for a speeding offence. She was going too fast for a speed awareness course or a fixed penalty, and was duly reported. She is going through the Single Justice Procedure, which is a new one on me, but I expect that it consists of one JP sitting alone with a clerk, dealing with the simpler cases. In days gone by I used to sit alone on Saturdays when I could usually expect about ten or fifteen cases, mostly remands or discharges. My maximum power was a penalty of one pound or one day's imprisonment, which could fill the bill for he usual overnight drunks and nuisances. The real work was deciding on bail, and that is a serious matter when you are on your own.
I shall be interested to see how the new procedure works in practice; no doubt my one-time colleagues will be able to fill me in.
