There is a patronising sod who was recently quoted thus:-
He said he had written to the judiciary because home secretaries had to remind them of sentencing guidelines "from time to time".
Most judges are appointed in their forties and fifties after at least two decades practising law. The gentleman who made the above comment has held his office for about twelve months. That is why judges spend quite a lot of time trying, and often failing, to remind successive Home Secretaries of the basics of English law.
