delivered the opinion of the court.
This suit was brought by the Continental Oil Company against the Attorney General and certain other officials of the. State of New Mexico to restrain the enforcement against the company, a distributor of and dealer in gasoline and other petroleum products in that State, of the provisions, of an act of the Legislature (Laws New Mexico, 1919, c. 93, p. 182) imposing an excise tax of 2 cents for each gallon of gasoline sold or used, and ail annual license tax of $50 for each distributing station or place of business. The case was here before under the name of
Askren
v.
Continental Oil Co.,
On the former appeal, it appeared upon the face of thé bill that plaintiff (appellee) purchases, gasoline in various States other than New México and ships it into that State, there to be sold and delivered; that it carries on business in two ways: first, gasoline is brought in from other States either in tank cars, in barrels, or in packages containing not less than. two~5'-gallon cans, and sold and delivered to customers in the original packages, in the same form and. condition as when received by plaintiff in the State *644 of New Mexico; as to which wé held plaintiff is engaged in interstate commerce and not hable to pay to the State a license tax for purchasing, shipping, and selling gasoline in that manner; secondly, a part of plaintiff’s business consists of selling gasoline from the tank car^'barrels,-and packages in quantities to suit purchasers;-and we held,that business of this kind is properly taxable by the laws of the State, although the gasoline is brought into thé State in interstate commerce; that the mere fact that it was produced in another State does not show a discrimination against the products of such State, and that sales from broken packages in' quantities to suit purchasers are- a subject of taxation within the legitimate power of the State. But these latter sales were little emphasized in the bill, which stressed the sales in original packages; and since from its averments it was impossible to determine whether the sales from broken packages were of substantial importance, we did not at that stage of the case go into the question whether the act was separable, blit reserved it for the final hearing, while affirming, the order for a temporary injunction.
Upon the going down of the mandate, plaintiff amended its bill "by averring that, in addition to carrying on the business of buying and selling gasoline and other petroleum products, it is using gasoline at each of its distributing stations within the State of New Mexico .(37 in number) in the operation of its automobile tank wagons and otherwise; that under the terms of the act it is prohibited from 'using this gasoline except upon the payment of the excise tax of 2 cents per gallon therefor; that this is a-property tax, voicj. under § 1 of Article VIII of the state constitution because not levied in proportion to .the value of the gasoline; and that the imposition of then tax denies to plaintiff the equal protection of the laws and amounts to a taking of its property without* due process of law, in contraven- . tion of the Fourteenth Amendment, and further is in *645 violation of the commerce clause of the Constitution of the United States.
Defendants answered, alleging that plaintiff’s sales in tank cars or other unbroken packages are insignificant as ■ compared with its sales made after original packages have been broken; denying that the act exacts of the plaintiff payment óf a license tax for the privilege of shipping or selling gasoline in interstate commerce, or of an excise tax on the gasoline sold in such commerce; averring that the State of New Mexico and its officers charged with enforcement, of the iaw do not construe the act as affecting intérstate commerce, and have no purpose or intention to enforce it so as to do so, or otherwisethan so far as intrastate commerce is concerned; and averring that any gasoline used by plaintiff at its distributing stations is no longer in. interstate commerce, but has become commingled with the general mass of property in the State, and a tax upon its. use is not void under, the state constitution,or a violation of the commerce clause or the Fourteenth Amendment.
The. case came on for final hearing upon stipulated facts as to the course of plaintiff’s business, from which it appeared that during the years 1918 and 1919 and the first seven months of 1920 its sales , of gasoline in bulk or from broken packages constituted about 94.5 per cent, of its aggregate business, and sales in original barrels, packages, or tank cars without breaking the packages about .5.5 per cent.; in addition, to which the company consumed in' the conduct of its own business gasoline equal to about 8 per cent, of its total sales. It was further stipulated that this represents the ordinary course of business of the company, but that future percentages will depend upon the demands of customers.
■.The trial court, after referring to our decision in 252 U. S.,. proceeded to pass upon the question whether the statute is separable and capable of being sustained so far *646 as it imposes á tax upon domestic business legitimately taxable. Reciting the language of the act, and reading it as including every distributor of gasoline whether selling at retail or in original packages, as imposing an excise tax upon all gasoline-whether sold in one way or the other, and as iriaking no exemption from either the license or the excise tax for persons selling gasoline or for gasoline sold in original packages, the court declared that it could not read an exemption into it without giving it a meaning the legislature might never have intended; and held the act not separable, but void as to both interstate and domestic business. Having reached this conclusion, the court found it unnecessary to pass upon the question whether the imposition of an excise tax of 2 cents per gallon upon the gasoline used by plaintiff in its automobiles and trucks employed in the business of distributing its wares for sale was in violation of thé provision of § 1, Art. VIII, of the constitution of the State because not levied in proportion to the value of the gasoline so used.
Assuming that, upon the question of construction, the District Court was right, and that the act manifests an intent to tax interstate as well as domestic transactions in gasoline, and is not in this respect capable of separation, still, so far as the excise tax is concerned — imposed as' it is upon the sale and use of gasoline according to the number of gallons sold and used — the divisible nature of the subject renders it feasible to control the operation and effect of the tax so as to prevent it from being imposed upon sales in interstate commerce, while allowing the State to enforce it with respect to domestic transactions; and with the allowance of an injunction limited accordingly plaintiff will receive the full protection to which it is entitled under the Constitution of the United States. The applicable rule is that laid down in
Ratterman
v.
Western Union Telegraph Co.,
But with the license tax it is otherwise. If the statute, is inseparable, then both by its terms and by its legal operation and effect this tax is imposed generally upon the entire business conducted, including interstate commerce as well as domestic; and the tax is void under the authority of

v.
Port of Mobile,
Upon the question óf sevelability, we are constrained to concur in the. view adopted by the District Court; and this notwithstanding our hesitation, in advance of a declaration by^ the court of last resort of the State, to adopt a construction brihging the law into conflict with the Federal Constitution.
Ohio Tax Cases,
•'. No doubt the State might impose a license tax upon the distribution and sale of gasoline in domestic commerce if it did not make its payment a condition of carrying on interstate oí foreign commerce. But the State has not done this by any act of legislation. Its executive and •administrative officials have disavowed a purpose to exact payment of the license tax for the privilege of carrying c,n interstate commerce. But the difficulty is that', since plaintiff, so far as appears, necessarily conducts its interstate and domestic commerce in gasoline indiscriminately at the same stations and by the same agencies, the license tax cannot be enforced at all without interfering with interstate commerce unless it be enforced otherwise than as prescribed by the statute — that is to say, without authority of law. Hence, it cannot be enforced at all.
With the excise tax ás imposed upon the use of gasoline by plaintiff at its distributing stations, in the operation of its automobile tank wagons and otherwise, we have no difficulty. Manifestly, gasoline thus used has passed *649 beyond interstate commerce, and the tax can be imposed upon its use, as well as upon the sale, of the same commodity in domestic trade, without .infringing plaintiff’s 'commercial rights under the Federal Constitution. Section 1, Article VIII, of the state constitution, invoked by plaintiff, reads: “Taxes levied upon tangible property shall be in proportion to the valúe thereof, and taxes shall be equal and uniform upon subjects of taxation of the same class.” Clearly, the first part of this refers to property taxation. The tax imposed by the act under consideration'upon the “salé or use of all gasoline sold or used in this State ” is not. property taxation, but in effect, .as in name, an excise tax. We see. no reásón to doubt the power of the State to select this commodity, as distinguished from others, in order to impose an excise tax upon its sale and use; and since the -tax operates impartially upon all, and with temtorial ■uniformity throughout, the State,' we-deem, it “equal and uniform upon subjects of taxation of the same class,” within the meaning of § 1 of Article VIII. .... ...
There is no substance in the objection that the excise tax, as applied to domestic sales and domestic use of gasoline, infringés plaintiff’s rights under the due process and ’equal protection; clauses of the Fourteenth Amendment. - The contention that it interferes with interstate commerce because the gasoline is the product of other States already has been disposed of.
The decree under review should, be reversed, and the , cause remanded with directions to grant a decree enjoining the enforcement as against plaintiff of the license tax without qualification, and of the excise tax upon the sale or use of- gasoline only-, with respect to. sales of gasoline brought from without the State into the State of New Mexico, and there sold and delivered to customers in the original packages, whether tank cars, barrels, or other packages, and in the same form and condition as when *650 received by plaintiff in that State; but without prejudice to the right of. the State,. through appellants or other officers, to enforce collection of the excise tax with respect to sales of gasoline from broken packages in quan-“ tities to suit purchasers, notwithstanding such gasoline may have been brought into the State in interstate commerce, and with respect to any and all jgasoline used by plaintiff at its distributing stations .or elsewhere ;in the State in the operation of its automobile tank wagons or otherwise; and without prejudice to the right of the State, through appellants or other officers, to require, plaintiff to render detailed statements of all gasoline received, sold, or used by it, whether in interstate commercé or not, to the end. that the State may the more readily enforce said excise tax to the extent that it has lawful power to enforce it as above stated. ■ • '*•■
