OPINION
The original opinion by this court in this cause appears in Evco v. Jones,
“In view of the concessions made in the brief in opposition filed by the Attorney General of New Mexico, and on examination of the record, petition for writ of certiorari is granted, judgment vacated and case remanded to the Court of Appeals of New Mexico for reconsideration in light of the position asserted by the Attorney General in the brief in opposition. The Chief Justice, Mr. Justice Black, Mr. Justice Harlan, and Mr. Justice Stewart are' of the opinion that certiorari should be denied.”
- The following positions were taken by the Attorney General in its said brief in opposition and in oral argument before this court upon rehearing after the remand: (1) because we concluded in our original opinion that the contracts, under which the taxpayer created and furnished reproducible originals of books, manuals, films and magnetic audio tapes to out-of-state purchasers, constituted sales of tangible personal property, rather than contracts for services as contended by the Commissioner, the in-state incidents, or the New Mexico activities of the taxpayer in the performance of these contracts, could not be taxed under the New Mexico Gross Receipts Tax without doing violence to the interstate commerce clause of the Federal Constitution; and (2) because of our determination that these contracts constituted sales, rather than contracts for services, the administrative burdens in apportioning receipts from these contracts are made “immensely more difficult.”
A resolution of the question, as to whether the State has exerted its power in proper proportion to the taxpayer’s activities within the State and to its consequent enjoyment of the opportunities and protection which the State has afforded, should not be dependent upon whether the contract under which the activities are performed is a contract of sale or a contract for services. The State may properly exact a constitutionally fair demand for that aspect of interstate commerce to which it bears a special relation. General Motors Corporation v. Washington,
In our opinion taxable incidents are equally apparent and are ascertainable with equal ease whether they arise out of a contract of sale or out of a contract for services. In any event, the relative ease of ascertainment of taxable incidents should not be the primary consideration in determining the validity or invalidity of a tax law.
As pointed out in our prior opinion, there is no question of apportionment in this case, because no question of multiple taxation is involved. The burden of showing the unconstitutionality of a tax upon interstate commerce rests upon the taxpayer. General Motors Corporation v. Washington, supra. In this the taxpayer failed.
We reinstate and reaffirm our opinion in Evco v. Jones, supra.
It is so ordered.
