delivered the opinion of the Court..
A Montana statute (§§2382 and 2383 Reviseji Codes 1921, as amended by c. 186, Laws 1925) levies an excise tax upon distributors and dealers engaged within the state in the business of refining, manufacturing, producing, or compounding gasoline or distillate aád selling the same in the state, and also upon those engaged within the-state in the business of shipping, transporting, or importing any gasoline or distillate into the state and selling the same in the state after it has been brought to rest therein. The basis of the tax is the
sale
of gasoline or distillate, and the statute, in that respect, makes no discrimination, except that it properly excludes from the operation of the tax the imported commodity while it continues subject to the commerce clause of the Constitution.
Raley & Bros.
v.
Richardson,
But the contention is that the statute discriminates against the Montana refiner because it is not extended
*501
to include gasoline or distillate shipped from other states and consumed or used after it has come to rest in Montana and its status in interstate commerce hag ended. Upon this ground the statute is challenged as constituting a denial of the equal protection of the laws, in contravention of the Fourteenth Amendment to the federal Constitution. The Supreme Court of Montana upheld the statute as valid,
This holding, as it was applied to the contention in the present case, seems to have beén the result of a- too literal reading of
Sonneborn Bros.
v.
Cureton,
But because the state legislature could have laid a tax upon the use of the commodity as well as upon its sale, it by no means follows that a failure to do so constituted a discrimination forbidden by the equal protection clause ■of the Fourteenth Amendment. That clause, does not prohibit classification; and the power of the state to classify for purposes of taxation is of wide range and flexibility, provided that the classification rest upon a substantial difference so that all persons similarly circumstanced will be treated alike. Statutes which tax one class of property while exempting another class necessarily result in imposing a greater burden upon the property taxed than would be the case if the omitted property were included. But such statutes do not create an inequality in the constitutional sense. Not is the imposition of an excise tax upon one occupation or one activity from which other and different occupations or activities are exempt, a denial of equal protection. It is enough if all in the same class are included and treated alike. These propositions are so firmly established by repeated decisioxis of’ this Court that further discussion is unnecessary.
Bell’s Gap R. R.
Co. v.
Pennsylvania,
The difference between an excise tax based on sales and one based on use of property is obvious and substantial. If the state sees fit'to tax one and not the other, there is. nothing in 'the federal Constitution to prevent; and it is not for this Court.to question the wisdom or expediency of the action taken or to overturn the taxoipon the ground that to include both would have resulted in a-more equitable, distribution of the burdens of taxation.
Judgment affirmed.
