The Crown Prosecutor has lost the file. The witnesses haven't turned up. The case has to be cancelled or postponed. In the afternoon court there's a list of 150 people who have been caught stopping on a red route. As one of the Lord Chancellor's lay magistrates, I have spent an increasing amount of the 21 years I've spent in court wondering why I'm devoting an unpaid day a week to work that I used to find challenging. I could be doing what I much prefer, which is writing cookbooks. Well, now I have had enough. In what I hope was a piece of public service, I have tried to do my bit, but disillusion has got the better of me.
