The Dutch constitution has an article giving everyone the right to private mail correspondence.

It was meant for physicial mail of course. I wonder if a judge would even see the difference.

A message is a message, regardless whether its deliver by electricity or a horse.

It guarantees that the content of sealed letters is never revealed, and that letters in transit are not opened by government officials, or any other third party.

I wonder how they are going to try to argue that a E2E encrypted message is not ‘sealed’.
