I need a view regarding Police procedure, anything we/he should consider doing now in preparation for the result and an idea of the consequences for someone well over the limit who is a first time offender at anything.
I am sorry he doesn't know and wasn't told.
Okay, if you can't give me help on that please describe what procedure the Police should have followed and what mitigating circumstances may be taken into account by the court.
Let's also take a guess, and it is a guess, that he drank 10 pints of lager. Unfortunately he doesn't remember how much he drank and doesn't know the breath test reading.
