What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the first listed appellant. The nature of this litigant falls into the category "natural person (excludes persons named in their official capacity or who appear because of a role in a private organization)". Your task is to determine the gender of this litigant. Use names to classify the party's sex only if there is little ambiguity (e.g., the sex of "Chris" should be coded as "not ascertained").

Opinion:
Lawrence F. CAFERO, Petitioner, v. NATIONAL LABOR RELATIONS BOARD, Respondent.
No. 433, Docket 28622.
United States Court of Appeals Second Circuit.
Argued April 21, 1964.
Decided Aug. 27, 1964.
Gene Crescenzi, New York City, for petitioner.
Arnold Ordman, Gen. Counsel, Domi-, nick L. Manoli, Associate Gen. Counsel,' Marcel Mallet-Prevost, Asst. Gen. Counsel, Melvin J. Welles, George B. Driesen, Attys., N. L. R. B., for respondent.
Before WATERMAN, KAUFMAN and MARSHALL, Circuit Judges.
PER CURIAM.
This is a petition brought pursuant to Section 10(f) of the National Labor Relations Act, as amended, 29 U.S.C. § 151 et seq., to review an order of the NationalLabor Relations Board dismissing a complaint of an employee which charged the respondent union with having violated Sections 8(b) (1) (A) and 8(b) (2) of the Act. Petitioner, who has been a member of the respondent union and a night shift proofreader at the New York Times since 1946, and who enjoyed senior job security status, was, at the union’s insistence, dropped to the bottom of the Times’s seniority list in 1962 after it had been discovered that petitioner was also employed full time during the day as a junior high school principal and had been steadily employed on a full time basis as either a teacher or a principal for the previous thirteen years. Section 33(f) of the collective bargaining agreement then in effect between respondent and the Times provided that an employee like petitioner might engage in pursuits other than composing room work for a period not exceeding 90 days per year without the loss of seniority job priority, and a union rule provided that “members who have full-time employment at other occupations are classed as ‘N.A.T.’ [not-at-trade] and are not eligible for employment at the printing trade except with the permission of proper officers of the local union when all available substitutes are employed.”
We think that we are com-'i pelled by this Court’s recent decision in ! N. L. R. B. v. Miranda Fuel Co., 326 F.2d 172 (2 Cir. 1963), to affirm the Board’s : dismissal of petitioner’s complaint. A j synthesis of the majority and concurring j opinions in that case indicates that a 1 complainant such as petitioner must ■ show, at the very least, that the union has . arbitrarily or capriciously discriminated i against him. This petitioner has failed ! to do. The determination by the National Labor Relations Board that the employment rule pursuant to which petitioner’s seniority priority was revoked, being designed to insure that available fpositions in the printing trade would go | to those workers in the trade who most needed the employment, was not inherently discriminatory, cf. Ford Motor Co. v. Huffman, 345 U.S. 330, 73 S.Ct. 681, 97 L.Ed. 1048 (1953), and the record amply supports the Board’s conclusion that the rule was not discriminatorily applied in practice.
The Board’s order dismissing the complaint is affirmed and the petition to review that order is denied.
