And if you read literally one paragraph from the bit that you quoted:

"The majority of national courts have generally recognized and accepted this principle, except for the part where European law outranks a member state's constitution. As a result, national constitutional courts have also reserved the right to review the conformity of EU law with national constitutional law"

And guess why and how they are able to do that - that's right, by retaining full sovereignty of their own justice systems. Even obeying rulings of the ECHR is purely a matter of courtesy more than anything, as neither EU nor ECHR have any enforcement mechanism beyond withholding funding, as many EU member states have proven time and time and time again.

I'm looking forward to seeing this in practice when Chat Control passes.

In what way? Most EU countries are for it, so of course they are going to implement it. Nothing to do with sovereignty.

except for some countries, the right to privacy is also written in the constitution, which would require changing said constitution, which is probably a lot harder than just implementing a law.

I can't say what it takes in every country, but in Denmark the procedure is as follows :

- The proposed change must pass a vote in parliament.

- There must then be an election to parliament.

- The new parliament must also vote in favor of the proposed change.

- Finally a popular vote must pass with at least 40% of all eligble voters voting for it. If less than 40% of eligble voters vote (regardless of where they cast their vote), the proposition fails.

It probably goes without saying that changing the Danish constitution is not a task taken lightly. The Danish constitution also explicitly forbids giving up soverenity.

Sounds like Danes have nothing to worry about then.

From my perspective it's just a way for activist lawyers and judges to force their agenda on their government. That also gives ineffective politicians a convenient excuse to why they can't do anything.

My impression is that the UK in particular has that problem. Other european countries take the more pragmatic and sane option of... simply ignoring the EU.
