From my understanding Charter of Fundamental Rights of the European Union is somewhat similar to US Constitution & amendments. Both do still allow government to restrict the freedoms granted by those in some situations though I do think the US Constitution does tend to set higher bar on the interference.

There have been EU laws which get struck down because they violated the Charter (e.g. Data Retention Directive).

Hopefully even if the worst comes to pass and the EU ends up enacting this law there are still the courts on the EU level and then the national governments and courts in countries where this type of surveillance is illegal can still decide to do whatever the want (i.e. national constitutions general take precedence over EU treaty obligations)
