Don't you think that the way of nomination of the members of the US Suprem Law Court is not really good ? I explain : They are nominated by the president, aren't they ? So, it's a major interference between the powers, executive and judiciary. It's not good for the good health of democracy that the Chief of State can say who will be member of this Law Court. Because after, the President can have a Law Court, which will follow his decision, without partiality. It's a risk. Montesquieu said that it should be better with a separation of the powers. But here, the executive control the judiciary power.
