I recollect reading GBH and murder the average was 60 days after the act. everyone reading this will say blimey that is quick.
For DD I was arrested April, charged July and the case heard August. Since I had professional registration. my prof body started whingeing about a year after that - which was eighteen months after the act - plenty of time to think why didnt I take a damned taxi ?
[ prof body hearings do NOT count as criminal proceedings ]
Here is a conspiracy trial which imploded ( failure to get the permission of the AG to bring the case ) Lets us call it an Alison Saunders special, The trial collapsed Jan 14 and was at least a year in preparation, and the plan was for a rematch in Jun 15, ( yes this month ). So he has been bailed for between 3 and 4 years
