I have a request in with the court to vary an order.   The order was made when I lived at address A but I have lived at various addresses, having spent the last 5 years at address B.  I have notified the court and police of address B.

Today, I recieved a letter from the court at address B, CC'd to address A.

This contained my name, my current address and basics of my offence.  Has anyone done anything wrong here?  It seems unfair that the current occupant of address A now has my full details (Data protection?)
