The justice of the peace is a sort of _mezzo termine_ between the magistrate and the man of the world, between the civil officer and the judge. A justice of the peace is a well-informed citizen, though he is not necessarily versed in the knowledge of the laws. His office simply obliges him to execute the police regulations of society; a task in which good sense and integrity are of more avail than legal science. The justice introduces into the administration a certain taste for established forms and publicity, which renders him a most unserviceable instrument of despotism; and, on the other hand, he is not blinded by those superstitions which render legal officers unfit members of a government. The Americans have adopted the system of English justices of the peace, but they have deprived it of that aristocratic character which is discernible in the mother-country. The governor of Massachusetts[80] appoints a certain number of justices of the peace in every county, whose functions last seven years.[81] He farther designates three individuals from among the whole body of justices, who form in each county what is called the court of sessions. The justices take a personal share in public business; they are sometimes intrusted with administrative functions in conjunction with elected officers;[82] they sometimes constitute a tribunal, before which the magistrates summarily prosecute a refractory citizen or the citizens inform against the abuses of the magistrate. But it is in the court of sessions that they exercise their most important functions. This court meets twice a year in the county town; in Massachusetts it is empowered to enforce the obedience of the greater number[83] of public officers.[84] It must be observed that in the state of Massachusetts the court of sessions is at the same time an administrative body, properly so called, and a political tribunal. It has been asserted that the county is a purely administrative division. The court of sessions presides over that small number of affairs which, as they concern several townships, or all the townships of the county in common, cannot be intrusted to any of them in particular.[85] In all that concerns county business, the duties of the court of sessions are therefore purely administrative; and if in its investigations it occasionally borrows the forms of judicial procedure, it is only with a view to its own information,[86] or as a guarantee to the community over which it presides. But when the administration of the township is brought before it, it almost always acts as a judicial body, and in some few cases as an administrative assembly.
