Suppose, for instance, that the president of the United States has committed the crime of high treason; the house of representatives impeaches him, and the senate degrades him; he must then be tried by a jury, which alone can deprive him of his liberty or his life. This accurately illustrates the subject we are treating. The political jurisdiction which is established by the laws of Europe is intended to try great offenders, whatever may be their birth, their rank, or their powers in the state; and to this end all the privileges of the courts of justice are temporarily extended to a great political assembly. The legislator is then transformed into a magistrate: he is called upon to admit, to distinguish, and to punish the offence; and as he exercises all the authority of a judge, the law restricts him to the observance of all the duties of that high office, and of all the formalities of justice. When a public functionary is impeached before an English or a French political tribunal, and is found guilty, the sentence deprives him _ipso facto_ of his functions, and it may pronounce him to be incapable of resuming them or any others for the future. But in this case the political interdict is a consequence of the sentence, and not the sentence itself. In Europe the sentence of a political tribunal is therefore to be regarded as a judicial verdict, rather than as an administrative measure. In the United States the contrary takes place; and although the decision of the senate is judicial in its form, since the senators are obliged to comply with the practices and formalities of a court of justice; although it is judicial in respect to the motives on which it is founded, since the senate is in general obliged to take an offence at common law as the basis of its sentence; nevertheless the object of the proceeding is purely administrative. If it had been the intention of the American legislator to invest a political body with great judicial authority, its action would not have been limited to the circle of public functionaries, since the most dangerous enemies of the state may be in the possession of no functions at all; and this is especially true in republics, where party favor is the first of authorities, and where the strength of many a leader is increased by his exercising no legal power. If it had been the intention of the American legislator to give society the means of repressing state offences by exemplary punishment, according to the practice of ordinary judgment, the resources of the penal code would all have been placed at the disposal of the political tribunals. But the weapon with which they are intrusted is an imperfect one, and it can never reach the most dangerous offenders; since men who aim at the entire subversion of the laws are not likely to murmur at a political interdict.
