* * * Each department should have a will of its own. * * * Each should have its own independence secured beyond the power of being taken away by either or both of the others. But at the same time the relations of each to the other should be so strong that there should be a mutual interest to sustain and protect each other. There should not only be constitutional means, but personal motives to resist encroachments of one or either of the others. Thus ambition would be made to counteract ambition, the desire of power to check power, and the pressure of interest to balance an opposing interest.
* * * The judiciary is naturally and almost necessarily, as has been already said, the weakest department. It can have no means of influence by patronage. Its powers can never be wielded for itself. It has no command over the purse or the sword of the nation. It can neither lay taxes, nor appropriate money, nor command armies, nor appoint to office. It is never brought into contact with the people by constant appeals and solicitations and private intercourse, which belong to all the other departments of Government. It is seen only in controversies or in trials and punishments. Its rigid justice and impartiality give it no claims to favor, however they may to respect. It stands solitary and unsupported, except by that portion of public opinion which is interested only in the strict administration of justice. It can rarely secure the sympathy or zealous support either of the Executive or the Legislature. If they are not, as is not unfrequently the case, jealous of its prerogatives, the constant necessity of scrutinizing the acts of each, upon the application of any private person, and the painful duty of pronouncing judgment that these acts are a departure from the law or Constitution can have no tendency to conciliate kindness or nourish influence. It would seem, therefore, that some additional guards would, under the circumstances, be necessary to protect this department from the absolute dominion of the others. Yet rarely have any such guards been applied, and every attempt to introduce them has been resisted with a pertinacity which demonstrates how slow popular leaders are to introduce checks upon their own power and how slow the people are to believe that the judiciary is the real bulwark of their liberties. * *
