The great weakness of the Charter lay in this, that no adequate sanction was attached to it, in order to ensure the enforcement of its provisions. The only expedient suggested for compelling the King to keep his promises was of a nature at once clumsy and revolutionary, and entirely worthless considered as a working scheme of government. Indeed, it was devised not so much to prevent the King from breaking faith as to punish him when he had done so. In other words, no proper constitutional machinery was invented to turn the legal theories of Magna Carta into practical realities. In its absence, we find what has sometimes been described as “a right of legalized rebellion” conferred on an executive committee of twenty-five of the King’s enemies.

This is the chief defect, but not the only one. Many minor faults and omissions may be traced to a similar root. All the great constitutional principles are in reality conspicuously absent. The importance of a council or embryo parliament, constituted on truly national lines (of which some glimmerings can be traced in 1213); the right of such a body to influence the King’s policy in normal times as well as in times of crisis; the doctrine of ministerial responsibility (already dimly foreshadowed in the reign of Richard); the need of distinguishing the various functions of government, legislative, judicial, and administrative—all these cardinal principles are completely ignored by the Charter. Not one of its many clauses affords evidence that the statesmen of the day had any conception, even of a rudimentary nature, of the principles of political science.

Only five of the sixty-three chapters can be said to bear directly on the subject of constitutional (as opposed to purely legal) machinery, and most of these do so only incidentally, namely, chapters 14, 21, 39, 61, and 62.

The Commune Concilium is indeed mentioned; and its composition and mode of summons are clearly defined in chapter 14. But it must be remembered that this chapter appears as a mere afterthought,—as an appendix to chapter 12; its incidental nature is proved by the fact that it has no counterpart in the Articles of the Barons. The rebel magnates were vitally interested in the narrow question of scutage, not in the wide possibilities involved in the existence of a national council. The Commune Concilium was dragged into the Charter, not on its own merits, but merely as a convenient method of preventing the arbitrary increase of feudal exactions. That this was so, is further proved by the fact that both parties were content to omit all mention of the Council from the re-issue of 1217, when an alternative way of checking the arbitrary increase of scutage had been devised.

If the framers of John’s Magna Carta had possessed any grasp of constitutional principles, they would gladly have seized the opportunity afforded them by the mention, however incidentally, of the Common Council, in chapters 12 and 14, in order to define most carefully the powers which they claimed for it. On the contrary, no list of its functions is drawn up; nor do the words of the Charter contain anything to suggest that it exercised any powers other than that of consenting to scutages and aids. Not a word is said of any right inherent in the Council to a share in legislation, to control or even to advise the Executive, or to concur in choosing the great ministers of the Crown. Neither deliberative, administrative, nor legislative powers are secured to it, while its control over taxation is strictly limited to the right to veto scutages and aids—that is say, it only extends over that very narrow class of exactions which affected the military tenants of the Crown. It is true that chapters 21 and 39 may possibly be read confirming the judicial power of the Council in a certain limited group of cases. Earls and barons are not to be amerced except by their peers (per pares suos), and the natural place for these “equals” of a Crown vassal to assemble for this purpose would be the Commune Concilium. This, however, is merely matter of inference; chapter 21 makes no mention of the Council; and it is equally possible that its requirements would be met by the presence among the officials of the Exchequer of a few Crown tenants.[[224]] Similar reasoning applies to the provisions of chapter 39 (protecting the persons and property of freemen, by insisting on the necessity of a “trial by peers”) so far as they affect earls and barons.

It is clear that the leaders of the opposition in 1215 did not consider the constitutional powers of a national Parliament the best safeguard of the rights and liberties theoretically guaranteed by the Charter. Only one practical or constitutional expedient seems to have occurred to them, namely, that embodied in chapter 61. Twenty-five barons were to be appointed by their fellow-barons to act as Executors of the Charter; but their functions were apparently only to be called into play in the event of King John or his officers breaking any of the provisions of the Charter. If this occurred, intimation might be made to a smaller sub-committee of four, chosen from the twenty-five, and these four would straightway ask the King to redress the grievance complained of. If this was not done within forty days, John granted to the Committee of twenty-five, assisted by “the whole community of the realm,” the right practically to make war upon him. He conferred on them in the most explicit terms full power “to distrain and distress us in all possible ways, by seizing our castles, lands, possessions, and in any other way they can, until the grievances are redressed according to their pleasure.”

Such a provision can hardly be described as constitutional, since it is rather the negation of all constitutional principles—nothing more nor less than legalized rebellion. Provision is made not for the orderly conduct of government, but rather to provide an organization for making war upon the king in certain abnormal circumstances which are defined. Such a scheme was clearly impracticable, and the fact that it recommended itself as a possible expedient to the barons speaks eloquently of their complete ignorance of the most elementary principles of the science of government. Civil war levied on a warrant granted beforehand by the king is treated as a constitutional expedient for the redress of particular grievances as they arise.[[225]]

The same inability to devise practical remedies for specific evils may be traced in several minor clauses of the Charter.[[226]] When John promised in chapter 16 that no one should be compelled to do greater service than had been formerly due from any holding, no attempt was made, in case of dispute, to provide constitutional machinery to define what such service actually was; while chapter 45, providing that only men who knew the law, and meant to keep it, should be made justiciars, sheriffs or bailiffs, laid down no criterion of fitness, and contained no suggestion of any way in which so laudable an ambition might be realized.

Thoughtful and statesmanlike as were the provisions of Magna Carta, and wide as was the ground they covered, many important omissions can be pointed out. Some crucial questions seem not to have been foreseen, and others, for example the liability to foreign service, were deliberately shelved[[227]]—thus leaving room for future misunderstandings. The praise, justly earned, by its framers for the care and precision with which they defined a long list of the more crying abuses, must be qualified in view of the failure to provide procedure to prevent their recurrence. Men had not yet learned the force of the maxim, so closely identified with all later reform movements in England, that a right is valueless without an appropriate remedy to enforce it.[[228]]
