What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
KINGSLAND, COMMISSIONER OF PATENTS, v. DORSEY.
No. 53.
Argued October 18-19, 1949.
Decided November 21, 1949.
Robert L. Stern argued the cause for petitioner. With him on the brief were Solicitor General Perlman, Assistant Attorney General Morison, Paul A. Sweeney, Melvin Richter and Roy C. Hackley.
William E. Leahy argued the cause for respondent. With him on the brief were William J. Hughes, Jr. and James F. Reilly.
Per Curiam.
Acting under the provisions of § 487 of the Revised Statutes (35 U. S. C. § 11), the Commissioner of Patents found after hearings that petitioner, an attorney, had been guilty of gross misconduct, and entered an order barring him from practice before the United States Patent Office. Pursuant to authority granted by the same provisions, the District Court reviewed the Commissioner’s order. Concluding that the hearings had been fairly conducted after due notice of charges and that there was substantial evidence to support the findings and action of the Commissioner, the District Court affirmed the order. 69 F. Supp. 788. The Court of Appeals reversed, 84 U. S. App. D. C. 264, 173 F. 2d 405. A majority of that court thought the notice of charges inadequate and the proceedings before the Commission unfair. It also held that the District Court had too narrowly restricted its scope of review in holding that substantial evidence was sufficient to support the findings. It apparently drew a distinction between the phrases “substantial evidence” and “substantial probative evidence.” Measuring the findings by the latter phrase, it held that the Commissioner’s findings were not supported by “substantial probative evidence.” Judge Edgerton, dissenting, thought the hearings had been fairly conducted and “the result just.” He agreed with the District Court that “substantial evidence” would have been sufficient but went on to say that he thought the “proof conclusive.”
The statute under which the Commissioner acted represents congressional policy in an important field. It relates to the character and conduct of “persons, agents, or attorneys” who participate in proceedings to obtain patents. We agree with the following statement made by the Patent Office Committee on Enrollment and Disbarment that considered this case: “By reason of the nature of an application for patent, the relationship of attorneys to the Patent Office requires the highest degree of candor and good faith. In its relation to applicants, the Office . . . must rely upon their integrity and deal with them in a spirit of trust and confidence . . . .” It was the Commissioner, not the courts, that Congress made primarily responsible for protecting the public from the evil consequences that might result if practitioners should betray their high trust. Having serious doubts as to whether the Court of Appeals acted properly here in nullifying the Commissioner’s order, we granted certiorari.
After an examination of the record we are satisfied that the findings were amply . supported whether the measure be “substantial evidence” or “substantial probative evidence.” The charge of unfairness in the hearings is, we think, wholly without support.
Since the narration of evidence and discussion of the proceedings sufficiently appear in the District Court’s opinion, reiteration here can serve no good purpose either for the parties or for the law.
The judgment of the Court of Appeals is reversed and that of the District Court affirmed.
It is so ordered.
Mr. Justice Douglas took no part in the consideration or decision of this case.
