It is the courts' job to block unconstitutional or otherwise illegal laws.

I believe someone said in a previous thread that a court in an EU member state had already found this mass surveillance on citizens who are not criminal suspects to be illegal under either their constitution or the Charter of Fundamental Rights, but I can't find it anymore. I am wondering why that is not sufficient to permanently block this.

Edit: This is not to say that you shouldn't resist the laws at every other level, too, because you definitely should.
