1. OP was charged with a contravention of s143.
2. He has confirmation from his insurers that he was covered.
3. Number 2 creates an argument that there is a reasonable doubt of guilt.
4. If the court thinks the charge is proved beyond reasonable doubt, there are very good grounds for a special reasons disposal which would allow the court not to impose points.
Can we just move on and await the outcome from the OP now?
4. Is actually based on balance of probabilities and not beyond reasonable doubt, it’s a magistrate / JP that will take the hearing, there isn’t a jury and summing up statements etc.
