As the business of courts of equity became more enlarged and more methodical,—as magistrates, for a long series of years, presided in the Court of Chancery, who were not bred to the Common Law,—as commerce, with its advantages and its necessities, opened a communication more largely with other countries,—as the Law of Nature and Nations (always a part of the law of England) came to be cultivated,—as an increasing empire, as new views and new combinations of things were opened,—this antique rigor and overdone severity gave way to the accommodation of human concerns, for which rules were made, and not human concerns to bend to them.
At length, Lord Hardwicke, in one of the cases the most solemnly argued, that has been in man's memory, with the aid of the greatest learning at the bar, and with the aid of all the learning on the bench, both bench and bar being then supplied with men of the first form, declared from the bench, and in concurrence with the rest of the Judges, and with the most learned of the long robe, the able council on the side of the old restrictive principles making no reclamation, "that the judges and sages of the law have laid it down that there is but ONE general rule of evidence,—the best that the nature of the case will admit."52 This, then, the master rule, that governs all the subordinate rules, does in reality subject itself and its own virtue and authority to the nature of the case, and leaves no rule at all of an independent, abstract, and substantive quality. Sir Dudley Ryder, (then Attorney-General, afterwards Chief-Justice,) in his learned argument, observed, that "it is extremely proper that there should be some general rules in relation to evidence; but if exceptions were not allowed to them, it would be better to demolish all the general rules. There is no general rule without exception that we know of but this,—that the best evidence shall be admitted which the nature of the case will afford. I will show that rules as general as this are broke in upon for the sake of allowing evidence. There is no rule that seems more binding than that a man shall not be admitted an evidence in his own case, and yet the Statute of Hue and Cry is an exception. A man's books are allowed to be evidence, or, which is in substance the same, his servant's books, because the nature of the case requires it,—as in the case of a brewer's servants. Another general rule, that a wife cannot be witness against her husband, has been broke in upon in cases of treason. Another exception to the general rule, that a man may not be examined without oath,—the last words of a dying man are given in evidence in the case of murder." Such are the doctrines of this great lawyer.
Chief-Justice Willes concurs with Lord Hardwicke as to dispensing with strict rules of evidence. "Such evidence," [he says,] "is to be admitted as the necessity of the case will allow of: as, for instance, a marriage at Utrecht, certified under the seal of the minister there, and of the said town, and that they cohabited together as man and wife, was held to be sufficient proof that they were married." This learned judge (commenting upon Lord Coke's doctrine, and Serjeant Hawkins's after him, that the oaths of Jews and pagans were not to be taken) says, "that this notion, though advanced by so great a man, is contrary to religion, common sense, and common humanity, and I think the devils, to whom he has delivered them, could not have suggested anything worse." Chief-Justice Willes, admitting Lord Coke to be a great lawyer, then proceeds in very strong terms, and with marks of contempt, to condemn "his narrow notions"; and he treats with as little respect or decorum the ancient authorities referred to in defence of such notions.
The principle of the departure from those rules is clearly fixed by Lord Hardwicke; he lays it down as follows:—"The first ground judges have gone upon, in departing from strict rules, is absolute strict necessity; 2dly, a presumed necessity." Of the first he gives these instances:—"In the case of writings subscribed by witnesses, if all are dead, the proof of one of their hands is sufficient to establish the deed. Where an original is lost, a copy may be admitted; if no copy, then a proof by witnesses who have heard the deed: and yet it is a thing the law abhors, to admit the memory of man for evidence." This enlargement through two stages of proof, both of them contrary to the rule of law, and both abhorrent from its principles, are by this great judge accumulated upon one another, and are admitted from necessity, to accommodate human affairs, and to prevent that which courts are by every possible means instituted to prevent,—A FAILURE OF JUSTICE. And this necessity is not confined within the strict limits of physical causes, but is more lax, and takes in moral and even presumed and argumentative necessity, a necessity which is in fact nothing more than a great degree of expediency. The law creates a fictitious necessity against the rules of evidence in favor of the convenience of trade: an exception which on a similar principle had before been admitted in the Civil Law, as to mercantile causes, in which the books of the party were received to give full effect to an insufficient degree of proof, called, in the nicety of their distinctions, a semiplena probatio.53
But to proceed with Lord Hardwicke. He observes, that "a tradesman's books" (that is, the acts of the party interested himself) "are admitted as evidence, though no absolute necessity, but by reason of a presumption of necessity only, inferred from the nature of commerce." "No rule," continued Lord Hardwicke, "can be more settled than that testimony is not to be received but upon oath"; but he lays it down, that an oath itself may be dispensed with. "There is another instance," says he, "where the lawful oath may be dispensed with,—where our courts admit evidence for the Crown without oath."
In the same discussion, the Chief-Baron (Parker) cited cases in which all the rules of evidence had given way. "There is not a more general rule," says he, "than that hearsay cannot be admitted, nor husband and wife as witnesses against each other; and yet it is notorious that from necessity they have been allowed,—not an absolute necessity, but a moral one."
It is further remarkable, in this judicial argument, that exceptions are allowed not only to rules of evidence, but that the rules of evidence themselves are not altogether the same, where the subject-matter varies. The Judges have, to facilitate justice, and to favor commerce, even adopted the rules of foreign laws. They have taken for granted, and would not suffer to be questioned, the regularity and justice of the proceedings of foreign courts; and they have admitted them as evidence, not only of the fact of the decision, but of the right as to its legality. "Where there are foreign parties interested, and in commercial matters, the rules of evidence are not quite the same as in other instances in courts of justice: the case of Hue and Cry, Brownlow, 47. A feme covert is not a lawful witness against her husband, except in cases of treason, but has been admitted in civil cases.54 The testimony of a public notary is evidence by the law of France: contracts are made before a public notary, and no other witness necessary. I should think it would be no doubt at all, if it came in question here, whether this would be a valid contract, but a testimony from persons of that credit and reputation would be received as a very good proof in foreign transactions, and would authenticate the contract."55
These cases show that
