Except that EU court rulings don’t count in countries that stupidly left, no matter when they happened.
You could pass a similar law yourself, but that’s probably not going to happen with either the abysmal Tories or the feckless centrist party Keir “I want to be Tony Blair” Starmer has turned Labour into in charge 😮💨
Nearly all EU rulings up until the UK left in 2019 are a part of British law. If the ruling was before the Brexit referendum then it would definitely count. Specifically with GDPR, the government confirmed that they adopted the EU’s law.
Furthermore, this isn’t a court ruling, it was a written reply from the European Commission, ie the people that wrote the law.
It’s nothing to do with GDPR acording to the link of the post (people should read more than headlines…)
