The judiciary is part of the goverment and as you can see in the letters from China and Russia the Goverment is asking GitHub to takedown repos referencing laws too. That does not make said laws moral or just.
If you think the age of the constitution means anything at all, then I am scared. Countries that do well, like Norway or Australia, have old constitutions — it means they have practice. Some good, safe democracies, like New Zealand, don't even have a constitution at all. Most of the remainder have constitutions that are old but have been comparatively recently re-enacted to make some superficial change here or there. (In the top ten, Iceland, Finnland and Ireland are probably the countries with the genuinely youngest constitutions.)
And anyone who has seen the Spanish handling of this situation, who thinks that Spain has separation of power, deserves the completely abandonment of the rule of law that is just around the corner.
