All three of those authorities have the ability and do suspend or remove and fine their licensed pilots for violations. With no requirement to enter the court system.
UK you need to go to court for a fine to be imposed and it is extremely rare for a license to be removed. So rare I can only think of one in the last 12 years and I think that could have been a medical removal for mental health reasons.
Even if a UK pilot gets a report in their airspace unless they land there and they are arrested on landing when a fine can then be imposed all that happens is their caa contacts the UK caa. And the UK cars sends a letter to the operator saying to stop being naughty.
Some places fine for coming off noise profiles etc but if the aircraft doesn't go back they can't enforce it. It's a bit of a swine checking for these sorts of liability on airframe when you take them on. Which is why quite a few always change the reg when acquiring a new airframe.
