OPINION
We accepted certification from the Court of Appeals on the question whether caliche is a mineral reserved to the United States under the Stock-Raising Homestead Act of 1916, 39 Stat. 862 (1916) (SRHA), and particularly under 43 U.S.C. § 299 (1982) of that Act. We determine that caliche is such a mineral.
This controversy arose when plaintiff Champlin Petroleum Company (Champlin) commenced road-building and caliche removal activities pursuant to an easement over the land of defendant Patricia H. Lyman nee Shafer (Shafer). The pleadings would indicate that Shafer owns the land pursuant to an SRHA patent, which contains a reservation to the United States of “coal and other minerals.” Other claims and parties are not relevant to this certification. The trial court granted summary judgment to Champlin, permanently enjoining Shafer from interfering with Champlin’s easement. The court further determined that, as a matter of law, caliche is a mineral reserved to the United States under the SRHA and thus Shafer was not entitled to compensation for its removal. Shafer appealed to the court of appeals, disputing (among other issues) the caliche question. The court of appeals certified the caliche question to us in accordance with State v. Manzanares,
We have never specifically decided whether caliche is a reserved mineral under the SRHA. In State ex rel. State Highway Commission v. Trujillo,
We noted, in Trujillo, the parties’ stipulation that the disputed material (monzonite) was “ ‘used (as gravel) as an aggregate for coarse and surfacing materials for highway construction.’ ”
The law is unsettled as to whether caliche, specifically, is a reserved mineral under certain federal patents. Poverty Flats Land & Cattle Co. v. United States,
This court has regarded caliche, in a general way, as a mineral similar to sand, gravel, clay, and limestone. Board of County Commissioners v. Good,
Although we have said above that we must follow the Supreme Court’s interpretation, and the parties to this appeal have pointed out the seemingly obvious conflicts in state and federal interpretations of the SRHA, none have favored us with any assistance whatever in researching or citing any cases addressing that issue. The decision in Western Nuclear represents the interpretation of a federal statute by the highest court in the land. We first note that matters concerning federal public lands in New Mexico are not exclusively within federal jurisdiction, at the same time recognizing that federal legislation respecting those lands necessarily overrides any conflicting state legislation. Kleppe v. New Mexico,
Likewise, state court interpretations of federal legislation are subject to United States Supreme Court review. See U.S. Const, art. Ill, § 2 (Supreme Court appellate-jurisdiction); U.S. Const, art. VI (Supremacy Clause); 28 U.S.C. § 1257 (1982) (federal question jurisdiction). See also Gulf Offshore Co. v. Mobil Oil Corp.,
In general, Congress intends that its laws shall operate uniformly throughout the United States, unimpaired by differences in state laws or state court decisions. Reconstruction Finance Corp. The Supreme Court granted certiorari in Western Nuclear “[i]n view of the importance of the case to the administration of the more than 33 million acres of land patented under the SRHA.”
To the extent, then, that Trujillo conflicts with Western Nuclear, it is overruled. We hold that caliche is a mineral reserved to the United States under the SRHA and, consequently, that Shafer is not entitled to be compensated for its removal.
This matter is remanded to the Court of Appeals for consideration of the other matters presented in the appeal.
