It is often hard to secure unanimity about the borders of legislative power, but that is much easier than to decide how far a particular adjustment diverges from what the judges deem tolerable. On such issues experience has over and over again shown the difficulty of securing unanimity. This is disastrous because disunity cancels the impact of monolithic solidarity on which the authority of a bench of judges so largely depends.
