It is purely a stealth tax. Anyone who is fined in the magistrates court will now pay a �15 surcharge. The magistrates have been given guidance that they must not reduce the fine to take account of the surcharge, so the �15 is on top of the fine.
The money goes to victim support and particularly to those victims of domestic violence. So all you speeding motorists and s172 failures will pay towards the rehabilitation of those who who beat up their wives. The irony is that the perpetrators of domestic violence dont get fined (usually) and are hardly ever ordered to pay compensation to their victims
