This suit was filed on October
22,
1937, and does not involve the amendment to art. vn, sec. n, par. i of the State constitution (Code, § 2-5001), adopted in 1937, and laws enacted pursuant thereto relating to taxes on intangibles. The question here presented must be determined under applicable provisions of the constitution and laws of this State as they existed before such constitutional amendment and statutes made thereunder. Counsel for the plaintiffs in error insist only on their general demurrer. Therefore the sole question to be determined is the taxability in Fulton County of the credits involved for the years 1931 through 1937. Thе constitutional provision above referred to and of force during the period involved in the instant case is: “All taxation shall be uniform upon the same class of subjects and ad valorem on all property subject to be taxed within the territorial limits of the authority levying the tax.” It is the contention of counsel for the plaintiffs in error that the State constitution can not limit by implication the power of the State to tax, but any such limitation must be declared in clear and unambiguous terms; that, since there is no contrary constitutional restraint, the State’s power of taxation extends to “all subjects over which the State is capable of demonstrating the practical fact of its power through its laws operating -territorially within the State.” We are clear that it is not essential to the existence of the rule precluding the State from, taxing property without its territorial limits that express language to this effect shall be in the organic law. This principle is declared in Cooley on Taxation (4th ed.), § 86, in the following language: “Great as is the sovereign power of any government to levy and collect taxes frоm its citizens, that power in a constitutional country has very distinct and positive
*553
limitations. Some of them inhere in its very nature, and exist, whether declared or not declared in the written constitution; but some of them it is not uncommon to specify, either out of abundant caution, or to keep them fresh in the minds of those who administer government. Other limitations spring from the peculiar form of our government, and from the relation of the States to the national authority. What may be called inherent limitations on the power to tax include . . the want of power to tax prоperty outside the territorial limits.” There is no power under the constitution to tax property outside the State’s territorial jurisdiction. The lack of extraterritorial power inheres in our Federal system, where the separate States and the people within them have surrendered a portion of sovereignty to the national government. It is well established that States, having entered into the Union, are not now possessed of external sovereignty. It has been stated that the reason for this rule is that to allow a State extraterritorial jurisdiction would bе to take from the jurisdiction of a sovereign sister State, and the States are equal.

Neff,
The opposing views on this question of the power of a State to
*554
tax intangible credits owned by non-residents against resident debtors have converged on this point of territorial jurisdiction. The contending armies of argument still clash on this battle line. It may be confidently asserted that the side which wins this battle wins the final victory — that it is decisive. This conflict arises doubtless from the peculiar nature of intangible properties, and the shrinking of the elements of time and space in commеrcial and business transactions, now so largely interstate, due to modern means of communication and transportation. This was commented on in Curry
v.
McCanless,
Taxes are levied on assets, not on liabilities. They are assessed against that which, according to universal practice and custom, is entered on bookkeeping records in black ink, not in red ink. Credits- are personal, individual property rights. They inhere in and belong to the creditor. He alone can legally enforce their conversion into money at maturity. In him the credit is an asset, entered on his bookkеeping records in blank ink. To the debtor, this class of property is not an asset but a liability. On his records it is entered in red ink. His relation to the transaction out of which the credit arises is' entirely different from that of the other party thereto. Since this intangible property right is personal to the creditor, is property only in him, and only he can legally compel the debtor to change this property from an intangible credit to tangible money or property for the creditor’s benefit, it has been in this country the all but unanimous rule to regard such intangibles as located at the domicile of the owner for the purpose of ad valorem taxation. As stated in Cleveland &c. R. Co.
v.
Pennsylvania,
Counsel for the plaintiffs in error argue that the situs of credits for the purpose of taxation may be either the domicile of the debtor or the domicile of the creditor; that, if the creditor is a resident of this State, the proper tax situs is Ms domicile, but if he is a non-resident and the debtor a resident, the proper tax situs is the domicile of the debtor. It may be argued that the Georgia rule applicable to the taxation of stocks in domestic and foreign corporations is similar to this pоsition; that is, that stocks in foreign corporations owned by persons domiciled in this State are taxable, whereas stocks in a domestic corporation are not taxable in this State. The reasons underlying, the two cases are essentially different. The resident owner of stocks in a foreign corporation has presumably transferred some of his properties, subject to ad valorem taxation in Georgia out of the State’s taxing jurisdiction, in exchange for the foreign stock. In the case of his acquiring stock in a domestic corporation, however, his property given in exchange therefor presumably remains within the taxing jurisdiction of the State. Applying the same reasoning to the taxing of credits, the opposite result is obtained. If a resident of Georgia lends money to a non-resident debtor, the money so loaned has gone beyond the taxing power of the State. The credit takes its place, and is taxable here. But if a non-resident lends money to a resident of this State, the money, or its equivalent property conversion, ordinarily becomes subject to an ad valorem prоperty tax in this State. The economic theory is that every credit represents tangible property of intrinsic value. In some instances it may represent services. But such services generally add to the value of some tangible property, e. g., mechanical services performed on a motor vehicle. The creditor transfers money or tangible real or personal property or services to the debtor ■ in consideration of a promise on his part to pay the creditor therefor either in money or specifics. So it may be safely assumed, in the great majority of business transactions resulting in the creation of credits, that there is a corresponding transfer of tangible property of the value of the debt thus created, which tangible property is *558 subject to an ad valorem property tax. Thus, if a non-resident lends $1000 in money to a resident of Fulton County, taking a note secured by deed conveying realty in Fulton County for the repayment of such loan, the State of the creditor’s domicile loses that much from its tangible-property tax digest (considering money as tangible property), and Gеorgia gains that much. Conversely, if a resident of Georgia lends money to a non-resident, Georgia loses from the tax digest the money, but the credit takes its place for the purpose of taxation. Where a loan is made by one resident to another, it might be claimed that such reasoning ■is not sound, that under our tax laws we would have two taxable dollars by such transaction where we had only one before. It will not be denied, however, that both the money loaned and the note taken for its repayment are property. Both have value. ' Both are subject to an ad valorem property tax. If both the debtor and the creditor are residents of the same county, then generally that county would have jurisdiction of both properties for taxation.
But we are asked on the authority and reasoning in State Tax Commission of Utah

Since the petition in the instant case was filed in the court below, this court has more than once passed on the question here involved adversely to the contеntions of the plaintiffs in error. See

They ask, however, if we should rule that those holdings, or any of them, are inconsistent with their position, that we review and overrule them or so much of them as may be held inconsistent with the view that the credits here involved are taxable in this State. It is ably argued that this court has bottomed the holdings in the cases named upon two series of its prior decisions, which are readily reconciled with the taxability оf the credits now under consid
*561
eration. The first of the series- they assert embraces the

cases:
Armour Packing Company
v.
Savannah,

Ga.

On motion for rehearing in
National Mortgage Corp.
v.
Suttles,
supra, this court said: “It was said in effect in the
Northwestern Mutual
case that a State can not tax property wholly beyond its territorial jurisdiction, and that any effort to do so would be in violation of the due-process clauses of the State and Federal constitutions ; also that, where a credit exists in favor of a non-resident in virtue of a loan, the fact that the debtor resides in this State would not, without more, confer jurisdiction to tax the credit here. . . In a case of this kind we áre confrontеd with a double limitation, since we must stay within both the State and Federal con
*562
stitutions; and even if it be assumed that the tax claimed in this case might be sustained under the Federal constitution as construed by the United States Supreme Court in the recent case of State Tax Commission of Utah
v.
Aldrich [supra], decided since our decision in the
Northwestern Mutual
case, we still can not so construe our Georgia due-process clause, in view of previous unanimous decisions by this court, including the
Northwestern Mutual
case. These decisions necessarily imply that it is the intent and policy of our State constitution that Georgia’s jurisdiction to tax is limited territorially tо Georgia, and that it can not reach into the bounds of other States. According to these decisions, there must be a tax situs in Georgia, and the mere residence of the debtor does not establish such situs. . . It is true that the constitution of Georgia manifests an intention to tax all property which the State has jurisdiction to tax, but the intention so manifested refers to jurisdiction under the same instrument, namely, the constitution of Georgia. It could not be properly said that the constitution of this State evinces an intention to make the Federal constitution, rather than its own рrovisions, the standard of State jurisdiction, in the matter of taxation. Nor would the fact that the United States Supreme Court may construe the fourteenth amendment as
not
imposing a particular limitation prevent this court from giving a different construction to our Georgia due-process clause and holding that under this clause the limitation
does
exist.

State,

139 (2) (
Thus, this court not only has decided this question previously, but also ha's construed its decisions. Both are adverse to the contentions of the plaintiffs in error. We are asked, however, to review and overrule these decisions. In
Davis
v.
Metropolitan Insurance Co.,
supra, it was ruled: “The request to review and overrule the decisions in
Columbus Mutual Life Insurance Co.
v.
Gullatt
and
Guardian Life Insurance Co.
v.
Gullatt
(supra), and
National Mortgage Corp.
v.
Suttles
(supra), is denied.” In the
Metropolitan
casе, there was a contention similar to that here, that, because the intangibles are not expressly exempted from taxation, the sovereign power of the State extends over the persons whose relationships are the origin of the property sought to be taxed, and such property is therefore required to be taxed. We are now asked in effect to review the review and to overrule the declination to overrule. It is true, as ruled in
