No they do not. That is an assumption. And again, no judge in any European court will allow this data as proof. They just don't know this yet.

A warrant will be issued by the judge, if no seed phrase was found then there is no proof.
And there is one more thing, they don’t need any prove if the one in court declares that he owns it..
Do you think european courts always play by the rules?
That is an assumption, but i know they don’t always play by rules by experience.
When you go to court agains a big player you will see the law going to trash and they doing what they want.
Who you think will win in a case of a pleb vs state?
Dont be naive.
