Premature Adjudication?

We tried a case of Drunk In Charge the other day, the alleged offence having taken place last October. I was surprised to see that one of the driver's bail conditions, imposed by a DJ(MC) was not to drive any motor vehicle. Since the man was a professional driver, he had not worked while awaiting trial and was living on his dwindling savings. That seemed a bit heavy to me, so when we eventually convicted him and imposed a ban (which is discretionary for this offence) we reduced it by a period that reflected the time that his bail condition had been in force.
