Isn't the issue in Poland that the judiciary is becoming less independent from the government? Separation of powers between government, parliament & justice system seems to be major feature in a democracy. So if the judiciary is indeed becoming less independent, isn't that a sign of decreasing democracy in a country?
I'm not familiar with the "spanish repression" you refer so I won't comment on that, but Navalny's detention... wasn't he detained because of he violated rules in his probation period[1]... by not being present when he was in a coma... having being poisoned by nerve agent!? I think it was quite fair to criticize that.
