We have rules but tradition has be to follow person. If a powerful person say something and rules comes in the way, then expect that rules will be bent or ignored altogether. Rules are written often written in a way that leaves them.open to.interpretations.

In India, at least, and probably elsewhere too, charialsmatic leaders are often the one who destroys instrlitutions because rules comes in their way and slows them down (whatever they are trying to achieve). Last charismatic leader before Modi was Indira Gandhi who imposed emergency.

I'd love to see lame leaders and powerful institutions in democracies.
