The Supreme Court, in Robinson v Chief Constable of West Yorkshire Police  UKSC 4, has declared that if “a third party such as a pedestrian is injured as a result of a negligent arrest on the street by a police officer, the police are liable in negligence where that injury was a reasonably foreseeable consequence of the police’s actions.”
It’s always annoyed me immensely that British police could almost never be held accountable for anything they did. It’s a recipe for carelessness, almost literally, when duty of care does not apply.
So I am pleased to see that a little bit more liability is finally appearing.
(I used to have an interesting in policing and the law a few years ago but local police officers weren’t very fond of that, I was made to understand, and I decided to drop it.)
