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:
Daniel UNTERMYER, Plaintiff-Appellant, v. Donald HELLBUSH, San Mateo County Probation Officer, Defendant-Appellee.
No. 72-2422.
United States Court of Appeals, Ninth Circuit.
Jan. 2, 1973.
Paul K. Robertson, Palo Alto, Cal., for plaintiff-appellant.
Evelle J. Younger, Atty. Gen., Edward A. Hinz, Jr., Chief Asst. Atty. Gen., Doris H. Maier, Asst. Atty. Gen., Robert R. Grannuchi, Karl S. Meyer, Deputy Attys. Gen., San Francisco, Cal., for defendant-appellee.
Before HAMLEY, KOELSCH, and WRIGHT, Circuit Judges.
PER CURIAM:
Appellant sought a writ of habeas corpus, attacking his conviction in the California state court for possession of marijuana. The district court denied the petition and, on this appeal, we affirm that disposition. Appellant was given a suspended sentence by the state court judge and is now on probationary status.
Appellant was stopped in a motor vehicle by a local police officer in Ather-ton, California. Marijuana was discovered in the vehicle, the officer seeing it in plain view. Untermyer here contests only the constitutionality of the initial stop, contending that the marijuana subsequently discovered should have been suppressed as the fruit of that stop.
Late in November, at 11:00 p.m., the police officer was patrolling in a residential area in which burglaries had recently been committed. He saw a small foreign car, darkened, parked in front of a darkened home. Appellant was walking from the house to the car. As the officer approached, appellant entered on the passenger side of the vehicle, and the car drove ahead 25 to 30 feet before the headlights were turned on. After following in his patrol car for a quarter of a mile, the officer stopped appellant’s car.
The reason given by the officer for the stop was that his suspicions had been aroused by the circumstances related above and he stated that his intention was to identify the occupants of the vehicle. On these facts, the district court determined that the police stop of the car did not constitute arbitrary or harassing action. The court correctly stated the rule in this circuit:
“The standard applicable under the Fourth Amendment to vehicle ‘stops’ by police for investigatory purposes, as distinguished from the more rigorous probable cause standard applicable to an arrest, is whether the ‘stop’ is based on a founded suspicion.”
Our statement of the rule in Wilson v. Porter, 361 F.2d 412, 415 (9th Cir. 1966) has since been reaffirmed since the Supreme Court’s decisions in Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968) and Sibron v. New York, 392 U.S. 40, 88 S.Ct. 1889, 20 L.Ed.2d 917 (1968). The Supreme Court has concluded that the Terry standard is no different from our own. Adams v. Williams, 407 U.S. 143, 92 S.Ct. 1921, 32 L.Ed.2d 612 (1972). In that case, the Court said:
“A brief stop of a suspicious individual, in order to determine his identity or to maintain the status quo momentarily while obtaining more information, may be most reasonable in light of the facts known to the officer at the time.” Adams at 146, 92 S.Ct. at 1923.
The unusual circumstances and appellant’s unusual conduct were such as to lead the local police officer “reasonably to conclude in light of his experience that criminal activity may be afoot.” Terry v. Ohio, 392 U.S. 1, 30, 88 S.Ct. 1868, 1884, 20 L.Ed.2d 889 (1968).
Affirmed.
