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:
MARTINEZ v. SANCHO, Treasurer.
No. 3505.
Circuit Court of Appeals, First Circuit.
Jan. 10, 1940.
F. Fernandez Cuyar and Carlos D. Vazquez, both of San Juan, P. R., for appellant.
William Cattron Rigby, of Washington, D. C. (B. Fernandez Garcia, of San Juan, P. R., and Nathan R. Margold, of Washington, D. C., on the brief), for appellees.
Before WILSON and MAGRUDER, Circuit Judges, and McLELLAN, District Judge.
PER CURIAM.
The plaintiff, appellant, bought a farm on which taxes for prior years had not been paid. Concededly when he bought the land, it was subject to a lien for the unpaid taxes for the current year and the three prior years, this by virtue of legislation by the Puerto Rican Legislature. Later, the defendants caused the property to be attached for these prior taxes and other taxes on the farm. Having paid or tendering taxes which had not become more “than three years old at the time of the attachment, the appellant sought an injunction against the attachment and sale of the land for the older taxes. Such an injunction against the defendants was ob-. tained in the District Court. The Supreme Court of Puerto Rico reversed the District Court and dismissed the complaint.
The basic question was and is one involving local laws and the construction of statutes enacted by the Insular Legislature. No provision of the Constitution of the United States, no Act of the Congress, no Treaty was discussed or considered by the Supreme Court of Puerto Rico. None of these is directly involved in this appeal. There is no substantial Federal question to support our jurisdiction. The amount of the taxes here at issue is less than two hundred dollars. The value in controversy is far less than the jurisdictional $5,'000. Our right to hear and determine the appeal rests upon the provisions contained in U.S.Code, Title 28, Section 225, 28 U.S.C.A. § 225, reading, so far as here applicable, as follows:
“§ 225. Appellate jurisdiction.
“(a) Review of final decisions. The circuit courts of appeal shall have appellate jurisdiction to review by appeal final decisions.
* * *
“Fourth. In the Supreme Courts of the Territory of Hawaii and of Puerto Rico, in all cases, civil or criminal, wherein the Constitution or a statute or treaty of the United States or any authority exercised thereunder is involved; in all other civil cases wherein the value in controversy, exclusive of interests and costs, exceeds $5,-000, and in all habeas corpus proceedings.”
The case at bar is not within the statute.
The appeal is dismissed for want of jurisdiction.
