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:
UNITED STATES of America and Donald E. Merrill, Agent of the Internal Revenue Service; Lee Groskopf, Manager, First National Bank of the Black Hills, Appellees, v. Robert C. OLSON, Appellant.
No. 79-1268.
United States Court of Appeals, Eighth Circuit.
Submitted Aug. 9, 1979.
Decided Aug. 17, 1979.
Robert C. Olson, pro se.
M. Carr Ferguson, Asst. Atty. Gen., Gilbert E. Andrews, Charles E. Brookhart and Philip I. Brennan, Attys., Tax Div., Dept, of Justice, Washington, D. C., and Robert D. Hiaring, U. S. Atty., Sioux Falls, S. D., on brief, for appellees.
Before HEANEY, ROSS and McMILLI-AN, Circuit Judges.
PER CURIAM.
This is an appeal from an order of the United States District Court for the District of South Dakota, filed March 21, 1979, enforcing an Internal Revenue summons.
Donald E. Merrill, an Internal Revenue Agent of the Internal Revenue Service, was assigned to conduct an investigation into the civil income tax liability of Robert C. Olson (hereinafter taxpayer) for the year 1977. In that investigation, Agent Merrill issued an Internal Revenue summons to Lee Groskopf, Manager, First National Bank of Black Hills, Robbinsdale Branch, directing Mr. Groskopf to appear before him on November 22, 1978, to give testimony and to produce bank records relating to taxpayer. The books, papers, records, and other data sought by the summons were described with reasonable particularity, were not already in the possession of the Internal Revenue Service, and were deemed necessary to the investigation of taxpayer’s federal tax liability for the year 1977. At the time the summons was issued, Agent Merrill had not made any recommendation that taxpayer be prosecuted for any matter connected with the investigation, and the Internal Revenue Service did not abandon, in an institutional sense, its pursuit of taxpayer’s civil tax liabilities. By letter dated November 6, 1978, taxpayer gave written notice to Gros-kopf and the bank not to comply with the summons.
To obtain compliance with the summons, the United States and Agent Merrill, on January 17, 1979, instituted the instant proceeding to obtain an order enforcing the summons. On January 18,1979, the district court issued a show cause order to the bank requiring it to explain, with specificity, why the summons should not be enforced. On March 21, 1979, the district court allowed taxpayer to intervene and on the same date, following the denial of the various motions, ordered the summons enforced. On March 23, 1979, taxpayer filed a notice of appeal from the order directing Lee Groskopf to comply with the summons, and a motion for a stay pending appeal. The stay was denied by the district court on March 26, 1979. Subsequently, on March 29 and April 11, 1979, the documents described in the instant summons were turned over to Agent Merrill, thus completing compliance with the summons.
Since the summons had been complied with, the instant case is in the same posture as was United States v. Toy National Bank, No. 79-1260 (8th Cir. June 22,1979) (unpublished slip opinion), in which this court ruled:
The United States has suggested that the appeal be dismissed as moot because the bank has fully complied with the IRS summons and the court order. Appellant does not dispute the fact that the order has been carried out, but argues that the issues it raises should nevertheless be decided. Because the records summoned have already been given to the IRS a decision by this court on the question whether the summons should have been ordered enforced could have no practical effect. The case is therefore moot. See, e. g., United States v. First Natl. Bank of Sturgis, S. D., 587 F.2d 909, 910 (8th Cir. 1978); Barney v. United States, 568 F.2d 116, 117 (8th Cir. 1978).
Although it is clear the case is moot, we nevertheless have considered taxpayer’s claims on appeal and we agree with the district court’s holding.
In closing, the government suggests that instead of simply dismissing the appeal, we dismiss the appeal and vacate the order enforcing the summons to prevent the “spawning [of] any legal consequences” by the enforcement order. Citing Donaldson v. United States, 400 U.S. 517, 531, 91 S.Ct. 534, 27 L.Ed.2d 580 (1971); United States v. Blue, 384 U.S. 251, 86 S.Ct. 1416, 16 L.Ed.2d 510 (1966); United States v. Munsingwear, 340 U.S. 36, 71 S.Ct. 104, 95 L.Ed. 36 (1950); United States v. Lyons, 442 F.2d 1144 (1st Cir. 1971). The government argues this course would leave the affected parties free to challenge the introduction of the summoned and produced materials at any subsequent proceeding, either civil or criminal. This is a matter that should in the first instance be presented to the district court and thus, though we dismiss the appeal, we remand the case to the district court, so that upon proper motion by the government or on its own motion, the court can consider vacation or modification of its order.
It is so ordered.
. Taxpayer did not note an appeal from the other orders entered on March 21 by the district court.
. While taxpayer did not appeal the denial of a stay pending appeal by the district court, the documents were turned over to the IRS agent before the time in which taxpayer might have filed such an appeal or sought a stay from this court. This procedure, which thwarted taxpayer’s opportunity for redress, should not be followed in the future.
