There is less qualified praise to be bestowed on the clauses of Magna Carta which deal with justice. The royal courts are no longer to attend the king's person--a vexatious practice when sovereigns were always on the move, and litigants and witnesses had to follow them from manor to manor--but are to be fixed at Westminster. General rules of indisputable equity are fixed for the conduct of the courts--no man is to be tried or punished more than once for the same offence; no one is to be arrested and kept in prison without trial; all arrested persons are to be sent before the courts within a reasonable time, and to be tried by a jury of their peers. Fines imposed on unsuccessful litigants are to be calculated according to the measure of their offence, and are not to be arbitrary penalties raised or lowered at the king's good pleasure according to the sum that he imagined that the offender could be induced to pay. No foreigners or other persons ignorant of the laws of England are to be entrusted with judicial or administrative offices.
There is only a single clause dealing with the grievances of the English Church, although Archbishop Langton had been the principal adviser in the drafting of the whole document. This clause, "that the English church shall be free," was, however, sufficiently broad to cover all demands. The reason that Langton did not descend to details was that the king had already conceded the right of free canonical election and the other claims of the clerical order in a separate charter, so that there was no need to discuss them at length.
The special clauses for the benefit of the city of London were undoubtedly inserted as a tribute of gratitude on the part of the barons for the readiness which the citizens had shown in adhering to their cause. There are other sections for the benefit of the commons in general, such as that which gives merchants full right of leaving or entering the realm with their goods on payment of the fixed ancient custom dues. But these clauses are less numerous than might have been expected--the framers of the document were, after all, barons and not burghers.
The most surprising part of the Great Charter to modern eyes is its sixty-first paragraph, that which openly states doubts as to the king's intention to abide by his promise, and appoints a committee of twenty-five guardians of the charter (twenty-four barons and the mayor of London), who are to coerce their master, by force of arms if necessary, to observe every one of its clauses. The twenty-five were to hear and decide upon any claims and complaints preferred against the king, and to keep up their numbers by co-optation, so that it would seem that the barons intended to keep a permanent watch upon the crown. The clause seems unnecessarily harsh and violent in its wording; but it must be remembered that John's character was well known, and that it was useless to stand on forms of politeness when dealing with him. It seems certain that the drafters of the charter were honest in their intentions, and did not purpose to set up a feudal oligarchy in the place of a royal autocracy. They were only insisting on the maintenance of what they believed to be the ancient and laudable customs of the realm.
