> If the President took the same approach as the court, it stands to reason that he could go into any public authority in Romania and block their decisions based on finding that they are not properly observing the Constitution, right? No. Article 80 you're quoting does not grant the President power. Instead it describes the role of President. This is rather unlike Article 146 that explicitly grants the Constitutional Court power or the other articles that explicitly grant the President power.
