Mandatory precision: this ruling has nothing to do with the European Union, which is that's why Switzerland is impacted, it has to do with the Council of Europe, which contains not only EU members but also non-EU european countries, including Türkiye (which has a tens of its population on the European continent) and even Putin's Russia until recently.

And that's where naming ECHR “top Europe Court” is a bit of a problem because for non-EU countries, this is in fact the only European court (and as such saying it's the “top court” is “technically correct” but misleading) and for EU members, there's no hierarchy between ECHR and CJEU, which is the Union's top court, but the later's actual coercive power is much higher, making the “top court” qualifier misleading when talking about the former.
