On the other hand, it may be argued that Magna Carta, while something less than a law, is also something more. A law made by the king in one national assembly might be repealed by the king in another; whereas the Great Charter was intended by the barons to be unchangeable. It was granted to them and their heirs for ever; and, in return, a price had been paid, namely, the renewal of their allegiance—a fundamental condition of John’s continued possession of the throne.[[183]]
Magna Carta has also been frequently described as a treaty. Such is the verdict of Dr. Stubbs.[[184]] “The Great Charter, although drawn up in the form of a royal grant, was really a treaty between the King and his subjects.... It is the collective people who really form the other high contracting party in the great capitulation.”[[185]] This view receives some support from certain words contained in chapter 63 of the Charter itself: “Juratum est autem tam ex parte nostra quam ex parte baronum, quod haec omnia supradicta bona fide et sine malo ingenio observabuntur.”
It is not sufficient to urge against this theory, as is sometimes done, that the concord was entered into in bad faith by one or by both of the contracting parties. It is quite true that the compromise it contained was accepted merely as a cloak under which to prepare for war; yet jurisprudence, in treating of formal documents granted under seal, pays no attention to sincerity or insincerity, but looks merely to the formal expression of consent.
Interesting questions might also be raised as to how far it is correct to extend to treaties the legal rule which declares void or voidable all compacts and agreements induced by force or fear. In a sense, every treaty which ends a great war would fall under such condemnation, since the vanquished nation always bows to force majeure. Such claims as the Great Charter may have to rank as a treaty are not, therefore, necessarily weakened by John’s subsequent contention that when granting it he was not a free agent.
There is, however, a more radical objection. A treaty is a public act between two contracting powers, who must, to meet the requirements of modern jurisprudence, be independent States or their accredited agents; while John and his opponents were merely fragments of one nation or State, torn asunder by mutual fears and jealousies.
Some authorities discard alike the theory of legislation and the treaty theory to make way for a third, namely, that Magna Carta is merely a contract, pact, or private agreement. M. Emile Boutmy is of this opinion. "Le caractère de cet acte est aisé à définir.[[186]] Ce n’est pas précisément un traité, puisqu’il n’y a pas ici deux souverainetés légitimes ni deux nations en présence; ce n’est pas non plus une loi; elle serait entachée d’irrégularité et de violence; c’est un compromis ou un pacte."[[187]]
Thus considered, the proudest act of the national drama would take its place in the comparatively humble legal category which includes such transactions as the hire of a waggon or the sale of a load of corn. There are, however, fatal objections to this theory also. It is difficult to see how the plea of “force,” if sufficient (as M. Boutmy urges) to render null the enactment of a public law, would not be even more effective in reducing a private agreement. If Magna Carta has no other basis than the declared consent of the contracting parties, it seems safer to describe it as a public treaty than as a private or civil pact devoid of political significance.
Other theories also are possible; as, for example, that the Great Charter is of the nature of a Declaration of Rights, such as have played so prominent a part in the political history of France and of the United States; while a recent American writer on English constitutional development seems almost to regard it as a code, creating a formal constitution for England—in a rude and embryonic form, it is true. “If a constitution has for its chief object the prevention of encroachments and the harmonizing of governmental institutions, Magna Carta answers to that description, at least in part.”[[188]]
It would be easy to find examples of attempts to compromise between these competing theories, by combining two or more of them. Thus, a high English authority declares that “the Great Charter is partly a declaration of rights, partly a treaty between Crown and people.”[[189]]
The essential nature of what took place at Runnymede, in June, 1215, is plain, when stripped of legal subtleties. A bargain was struck between the King and the rebel magnates, the purport of which was that the latter should renew their oaths of fealty and homage, and give security that they would keep these oaths, while John, in return, granted “to the freemen of England and their heirs for ever” the liberties enumerated in sixty-three chapters. No one thought of asking whether the transaction thus concluded was a “treaty” or a private “contract.”
