The President, who exercises a limited power, may err without causing great mischief in the State. Congress may decide amiss without destroying the Union, because the electoral body in which Congress originates may cause it to retract its decision by changing its members. But if the Supreme Court is ever composed of imprudent men or bad citizens, the Union may be plunged into anarchy or civil war.
The real cause of this danger, however, does not lie in the constitution of the tribunal, but in the very nature of Federal Governments. We have observed that in confederate peoples it is especially necessary to consolidate the judicial authority, because in no other nations do those independent persons who are able to cope with the social body, exist in greater power or in a better condition to resist the physical strength of the Government. But the more a power requires to be strengthened, the more extensive and independent it must be made; and the dangers which its abuse may create are heightened by its independence and its strength. The source of the evil is not, therefore, in the constitution of the power, but in the constitution of those States which render its existence necessary.
