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.
In some cases there is some confusion over who should be listed as the appellant and who as the respondent. This confusion is primarily the result of the presence of multiple docket numbers consolidated into a single appeal that is disposed of by a single opinion. Most frequently, this occurs when there are cross appeals and/or when one litigant sued (or was sued by) multiple litigants that were originally filed in district court as separate actions. The coding rule followed in such cases should be to go strictly by the designation provided in the title of the case. The first person listed in the title as the appellant should be coded as the appellant even if they subsequently appeared in a second docket number as the respondent and regardless of who was characterized as the appellant in the opinion.
To clarify the coding conventions, consider the following hypothetical case in which the US Justice Department sues a labor union to strike down a racially discriminatory seniority system and the corporation (siding with the position of its union) simultaneously sues the government to get an injunction to block enforcement of the relevant civil rights law. From a district court decision that consolidated the two suits and declared the seniority system illegal but refused to impose financial penalties on the union, the corporation appeals and the government and union file cross appeals from the decision in the suit brought by the government. Assume the case was listed in the Federal Reporter as follows:
United States of America,
Plaintiff, Appellant
v
International Brotherhood of Widget Workers,AFL-CIO
Defendant, Appellee.
International Brotherhood of Widget Workers,AFL-CIO
Defendants, Cross-appellants
v
United States of America.
Widgets, Inc. & Susan Kuersten Sheehan, President & Chairman
of the Board
Plaintiff, Appellants,
v
United States of America,
Defendant, Appellee.
This case should be coded as follows:Appellant = United States, Respondents = International Brotherhood of Widget Workers Widgets, Inc., Total number of appellants = 1, Number of appellants that fall into the category "the federal government, its agencies, and officials" = 1, Total number of respondents = 3, Number of respondents that fall into the category "private business and its executives" = 2, Number of respondents that fall into the category "groups and associations" = 1.
Note that if an individual is listed by name, but their appearance in the case is as a government official, then they should be counted as a government rather than as a private person. For example, in the case "Billy Jones & Alfredo Ruiz v Joe Smith" where Smith is a state prisoner who brought a civil rights suit against two of the wardens in the prison (Jones & Ruiz), the following values should be coded: number of appellants that fall into the category "natural persons" =0 and number that fall into the category "state governments, their agencies, and officials" =2. A similar logic should be applied to businesses and associations. Officers of a company or association whose role in the case is as a representative of their company or association should be coded as being a business or association rather than as a natural person. However, employees of a business or a government who are suing their employer should be coded as natural persons. Likewise, employees who are charged with criminal conduct for action that was contrary to the company policies should be considered natural persons.
If the title of a case listed a corporation by name and then listed the names of two individuals that the opinion indicated were top officers of the same corporation as the appellants, then the number of appellants should be coded as three and all three were coded as a business (with the identical detailed code). Similar logic should be applied when government officials or officers of an association were listed by name.
Your specific task is to determine the total number of appellants in the case that fall into the category "natural persons". If the total number cannot be determined (e.g., if the appellant is listed as "Smith, et. al." and the opinion does not specify who is included in the "et.al."), then answer 99.

Opinion:
LEE FOO v. NAGLE, Commissioner of Immigration.
No. 6614.
Circuit Court of Appeals, Ninth Circuit.
May 16, 1932.
Joseph P. Fallon, of San Francisco, Cal., for appellant.
Geo. J. Hatfield, U. S. Atty., and L. E. Kilkenny, Asst. U. S. Atty., both of San Francisco, Cal., for appellee.
Before WILBUR and SAWTELLE, Circuit Judges.
WILBUR, Circuit Judge.
This appeal is taken from an order of the District Court denying petition for writ of habeas corpus. Appellant, Lee Foo, claims to be the son of Lee Wot, a native-born citizen of the United States. Upon application for admission into the United States, Lee Foo, his alleged father, Lee Wot, also known as Lee Shew Nom, and his alleged cousin, Lee Wah, were examined in detail as to family life- and the home in Ping On village, China. The testimony of the three witnesses agreed in the main as to many intimate details of the home, family life, relationships, ancestral graves, etc. However, during the course of' the examination certain discrepancies between the testimony of the 'witnesses were-developed, and on the basis of these discrepancies the immigration authorities rejected the testimony as to the relationship between the alleged father and son, and held that the applicant had not sustained the burden of proof upon him to show that he is a citizen of the United States, and for that reason directed that he be returned to China. While he was detained for that purpose, he instituted these proceedings.
Some of the alleged discrepancies in regard to the ancestral graves, tombstones, etc., are not of sufficient consequence to justify setting forth in an opinion. On the other hand, the alleged father testified that his oldest son was married, that he lived in the family home in the Ping On village, and that his marriage name was Lee Ngoot L-oy, and his other name was Lee Fong Nai. The appellant testified that his oldest brother had no marriage name, and that he knew this to be so because he lived in the home with him. A similar situation arose with reference to the marriage name of the nephew of the alleged father, living in the adjoining house in the Ping On village. The alleged father testified that his brother’s oldest son was named Lee Wee, that he was married and his marriage name was Lee Em Loy. Appellant, on the other hand, testified that this cousin had no marriage name, and, although his attention was directed to the fact that his alleged father had testified that Lee Wee had a marriage name, the applicant testified to the contrary.
There was also a discrepancy as to the name of the wife of Lee Wee. The other members of the family testified that her name was Dea Shee, while the applicant testified that her name was Jin Shee.
The alleged father testified that, when he-was in China from November, 1927, to June,. 1930, he intended bringing the applicant to the United States with him; that the applicant was willing to come with him, and would have come with him if he could have secured passage, that he told the applicant of his plan to bring him to the United States, and, when he found that he could not get passage for him, told him that he would send for him later; that the applicant quit school in 192-9 in order to prepare to come to the United States. The applicant, however, testified that the subject of his coming to the United States was not discussed between them; that his father never expressed any desire or intention of having him come to the United States with him when he last returned, and that he did not quit school on account of the proposed trip to the United States, nor did such trip have any effect upon him in that regard; that he quit school because he did not want to attend any more and that was the only reason.
The alleged father testified to an outside window in each bedroom in the house in China closed by a shutter and iron grating. The appellant, who lived in the house from the time of his birth until he left to come to the United States, testified that there were no windows in the outer walls of the house.
In view of these discrepancies, and notwithstanding the many agreements in the evidence as to the many details upon which the witnesses were questioned by the immigration authorities, we cannot say that the rejection of the testimony was so arbitrary as to have deprived the appellant of a fair hearing.
Order affirmed.
