Davemano Yes Involuntary manslaughter, that was the phase I was trying to remember. It means he did not intend to cause harm, but harm occurred due to his action or inaction. That is why the sentence is 3 years.
Douglas9401, Judges are appointed from qualified legal professionals normally Barristers who have many years expierience in the law. They would start as part time judges at a lower court before being moved up to Crown / High Court. There are sentencing guidelines for every offence and Judges have to abide by them by them. The skill comes in being able to 'Make Judgement' about the merits of each case and advise the lawyers and jury. In most courts it is the jury who make the decision guilty or not guilty after a summing up by the judge ,again it is in the summing up that a judge needs the 'wisdom' to get it correct.
So a Judge does not go to 'Judge School' he/she gains expierience as a legal professional, which takes several years, and after more years experience as a fully qualified barrister can become a judge.
It is worth mentioning that lawyers and barristers are not paid a salary. They are paid fees on a case by case basis so the more cases they take the more they earn. Also the more successful they are at getting their clients found not guilty the more they can charge for taking a case.
A Judge on the other hand must be impartial they are paid a salary, so that they have no incentive get more money by taking more cases and getting charges dropped or getting not guilty pleas.
Once you become a judge and get a salary you can NEVER go back to being a fee earning lawyer or barrister .
For this reason many lawyers and barristers do not want to become judges and will refuse the chance if it is offered.
