@berlinfokus Sure, this is not the US, the powers here are not concentrated that much, but I do expect a lot of attempts to change the constitution.
Re „unauthorised entities acting without impunity“: this is already happening (though to a lesser extent), e.g., the extradition of Maja by state police and prosecutors (not elected) in violation of a direct order of the constitutional court.
Seperation of power is only meaningful if there are actual consequences when one power ignores the others…
