Agree, I don’t know why people are saying the punishment will be less for a second offence. Generally in law, it always a greater punishment if you do it again.
I also don’t think there is any ‘double jeopardy’. It’s a rolling three year period, so while two of the three years in the second charge were included in the first, the year we have breached again was the third year, which wasn’t included in the first charge. I think we may end up with more than six points deducted for the second charge.
