The whole of this subject has been fully and satisfactorily explained in the very able and learned argument of the counsel who contended for the maintenance of the original decision of this court in Hepburn v. Griswold. He showed by the debates that congress has been moved, in all its actions under the coinage power, only by an anxious desire to ascertain the true relative value of the two precious metals, and to fix the coinage in accordance with it; and that in no case has any deviation from intrinsic value been permitted except in coins for fractional parts of a dollar, and even that has been only of so slight a character as to prevent them from being converted into bullion, the actual depreciation being made up by their portability and convenience.

It follows, from this statement of the action of congress in altering at different times the alloy of certain coins, that the assumption of power to stamp metal with an arbitrary value and give it currency, does not rest upon any solid foundation, and that the argument built thereon goes with it to the ground.

I have thus far spoken of the legal tender provision with particular reference to its application to debts contracted previous to its passage. It only remains to say a few words as to its validity when applied to subsequent transactions.

So far as subsequent contracts are made payable in notes of the United States, there can of course be no objection to their specific enforcement by compelling a delivery of an equal amount of the notes, or by a judgment in damages for their value as estimated in gold or silver dollars, nor would there be any objection to such enforcement if the legal tender provision had never existed. From the general use of the notes throughout the country and the disappearance of gold and silver coin from circulation, it may perhaps be inferred in most cases, that notes of the United States are intended by the parties where gold or silver dollars are not expressly designated, except in contracts made in the Pacific states, where the constitutional currency has always continued in uses. As to subsequent contracts, the legal tender provision is not as unjust in its operation as when applied to past contracts, and does not impair to the same extent private rights. But so far as it makes the receipt of the notes, in absence of any agreement of the parties, compulsory in payment of such contracts, it is, in my judgment, equally unconstitutional. This seems to me to follow necessarily from the duty already mentioned cast upon congress by the coinage power,—to create and maintain a uniform metallic standard of value throughout the Union. Without a standard of value of some kind, commerce would be difficult, if not impossible, and just in proportion to the uniformity and stability of the standard is the security and consequent extent of commercial transactions. How is it possible for congress to discharge its duty by making the acceptance of paper promises compulsory in all future dealings—promises which necessarily depend for their value upon the confidence entertained by the public in their ultimate payment, and the consequent ability of the holder to convert them into gold or silver—promises which can never be uniform throughout the Union, but must have different values in different portions of the country; one value in New York, another at New Orleans, and still a different one at San Francisco.

Speaking of paper money issued by the states,—and the same language is equally true of paper money issued by the United States—Chief Justice Marshall says, in Craig v. The State of Missouri: "Such a medium has been always liable to considerable fluctuation. Its value is continually changing; and these changes, often great and sudden, expose individuals to immense loss, are the sources of ruinous speculations, and destroy all confidence between man and man. To cut up this mischief by the roots, a mischief which was felt by the United States, and which deeply affected the interest and prosperity of all, the people declared in their constitution that no state should emit bills of credit."

Mr. Justice Washington, after referring, in Ogden v. Saunders, to the provision of the constitution declaring that no state shall coin money, emit bills of credit, make anything but gold and silver coin a tender in payment of debts, says: "These prohibitions, associated with the powers granted to congress 'to coin money and to regulate the value thereof, and of foreign coin,' most obviously constitute members of the same family, being upon the same subject and governed by the same policy. This policy was to provide a fixed and uniform standard of value throughout the United States, by which the commercial and other dealings between the citizens thereof, or between them and foreigners, as well as the moneyed transactions of the government, should be regulated. For it might well be asked, Why vest in congress the power to establish a uniform standard of value by the means pointed out, if the states might use the same means, and thus defeat the uniformity of the standard, and consequently the standard itself? And why establish a standard at all for the government of the various contracts which might be entered into, if those contracts might afterwards be discharged by a different standard, or by that which is not money, under the authority of state tender laws? It is obvious, therefore, that these prohibitions in the tenth section are entirely homogeneous, and are essential to the establishment of a uniform standard of value in the formation and discharge of contracts."

It is plain that this policy cannot be carried out, and this fixed and uniform metallic standard of value throughout the United States be maintained, so long as any other standard is adopted, which of itself has no intrinsic value and is forever fluctuating and uncertain.

For the reasons which I have endeavored to unfold, I am compelled to dissent from the judgment of the majority of the court. I know that the measure, the validity of which I have called in question, was passed in the midst of a gigantic rebellion, when even the bravest hearts sometimes doubted the safety of the republic, and that the patriotic men who adopted it did so under the conviction that it would increase the ability of the government to obtain funds and supplies, and thus advance the national cause. Were I to be governed by my appreciation of the character of those men, instead of my views of the requirements of the constitution, I should readily assent to the views of the majority of the court. But, sitting as a judicial officer, and bound to compare every law enacted by congress with the greater law enacted by the people, and being unable to reconcile the measure in question with that fundamental law, I cannot hesitate to pronounce it as being, in my judgment, unconstitutional and void.

In the discussions which have attended this subject of legal tender there has been at times what seemed to me to be a covert intimation, that opposition to the measure in question was the expression of a spirit not altogether favorable to the cause, in the interest of which that measure was adopted. All such intimations I repel with all the energy I can express. I do not yield to any one in honoring and reverencing the noble and patriotic men who were in the councils of the nation during the terrible struggle with the rebellion. To them belong the greatest of all glories in our history,—that of having saved the Union, and that of having emancipated a race. For these results they will be remembered and honored so long as the English language is spoken or read among men. But I do not admit that a blind approval of every measure which they may have thought essential to put down the rebellion is any evidence of loyalty to the country. The only loyalty which I can admit consists in obedience to the constitution and laws made in pursuance of it. It is only by obedience that affection and reverence can be shown to a superior having a right to command. So thought our great Master when he said to his disciples: "If ye love me, keep my commandments."
