opinion: 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.

instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the issue area of the Court's decision. Determine the issue area on the basis of the Court's own statements as to what the case is about. Focus on the subject matter of the controversy rather than its legal basis. In specifying the issue in a legacy case, choose the one that best accords with what today's Court would consider it to be. Choose among the following issue areas: "Criminal Procedure" encompasses the rights of persons accused of crime, except for the due process rights of prisoners. "Civil rights" includes non-First Amendment freedom cases which pertain to classifications based on race (including American Indians), age, indigency, voting, residency, military or handicapped status, gender, and alienage. "First Amendment encompasses the scope of this constitutional provision, but do note that it need not involve the interpretation and application of a provision of the First Amendment. For example, if the case only construe a precedent, or the reviewability of a claim based on the First Amendment, or the scope of an administrative rule or regulation that impacts the exercise of First Amendment freedoms. "Due process" is limited to non-criminal guarantees. "Privacy" concerns libel, comity, abortion, contraceptives, right to die, and Freedom of Information Act and related federal or state statutes or regulations. "Attorneys" includes attorneys' compensation and licenses, along with trhose of governmental officials and employees. "Unions" encompass those issues involving labor union activity. "Economic activity" is largely commercial and business related; it includes tort actions and employee actions vis-a-vis employers. "Judicial power" concerns the exercise of the judiciary's own power. "Federalism" pertains to conflicts and other relationships between the federal government and the states, except for those between the federal and state courts. "Federal taxation" concerns the Internal Revenue Code and related statutes. "Private law" relates to disputes between private persons involving real and personal property, contracts, evidence, civil procedure, torts, wills and trusts, and commercial transactions. Prior to the passage of the Judges' Bill of 1925 much of the Court's cases concerned such issues. Use "Miscellaneous" for legislative veto and executive authority vis-a-vis congress or the states.
