The Court's statement that it is 'tempting' to acknowledge the authoritativeness of tradition in order to 'curb the discretion of federal judges' is, of course, rhetoric rather than reality; no government official is 'tempted' to place restraints upon his own freedom of action, which is why Lord Acton did not say 'Power tends to purify.' The Court's temptation is in the quite opposite and more natural direction -- towards systematically eliminating checks upon its own power; and it succumbs.
