In reply to JohnnyW:
I agree, but I'm struggling with the logic.
Estate is illegally killing raptors but criminal charges can't be brought for whatever reason.
Using 'balance of probability' rather than 'beyond reasonable doubt' civil case is proved that they are illegally killing raptors. On this basis licence to kill other birds is revoked.
Estate then continues to kill raptors illegally, plus other birds that it's now illegal for them to kill.
Then what?
