EXOD732 Do not curse a nasi. It is impossible for people to live together unless they accept that one individual be their leader and everyone heeds what he says. After all, people differ greatly in their ideas and rarely see things the same way. Without a leader, a group seldom agrees on any one opinion or course of action. Such lack of harmony prevents accomplishing goals for the common good. Therefore, people must accept upon themselves that one leader will make the decisions and everyone will cooperate with what he says and do what needs to be done according to his way of thinking. The head of the Great Sanhedrin is acknowledged as the nation's guide regarding the laws and ways of the Torah. The king is the acknowledged authority on civil order. Because the leaders serve society in such beneficial ways, we cannot dispute their decisions, so we are forbidden to curse them even in private when no one hears. It is the way of the world that once someone allows himself to curse others privately, he eventually will speak out against them openly and disruptive disputes will break out.
