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, Plaintiff-Appellee, v. Wilfred Henry SORRELL, Defendant-Appellant.
No. 72-1232.
United States Court of Appeals, Seventh Circuit.
Argued Dec. 5, 1972.
Decided Jan. 17, 1973.
Bryan Borman, Milwaukee, Wis., for defendant-appellant.
David J. Cannon, U. S. Atty., Terry E. Mitchell, D. Jeffrey Hirschberg, Asst. U. S. Attys., Milwaukee, Wis., for plaintiff-appellee.
Before FAIRCHILD, PELL and SPRECHER, Circuit Judges.
SPRECHER, Circuit Judge.
The defendant, Wilfred Henry Sorrell, was charged in a single-count indictment with wilfully failing and refusing to comply with an order to report for induction into the Armed Forces “in that he refused to comply with instructions, rules and procedures prescribed for registrant processing,” in violation of 50 U.S.C. App. § 462. Trial was held before the court and defendant was found guilty on September 22, 1971. Numerous alleged errors are raised in this appeal, two of which will be discussed. We conclude that Sorrell’s conviction must be reversed.
I
Defendant argues that the indictment under which he was convicted was so vague that it failed to give him reasonable notice of the acts constituting the offense for which he was charged. The indictment was framed in language similar to that contained in the statute, which provides in part that “any person . . . who in any manner shall knowingly fail or neglect or refuse to perform any duty required of him under or in the execution of this title, ... or rules, regulations, or directions made pursuant to this title .” shall be guilty of an offense punishable by imprisonment for not more than five years and a maximum fine of $10,000. 50 U.S.C. App. § 462. Specifically, the indictment charged that the defendant, on or about October 9, 1969, in the city of Milwaukee,
“did knowingly, wilfully and unlawfully fail to perform a duty resting upon him under the Military Selective Service Act of 1967 and the Regulations in that, having been classified as I-A, he did wilfully fail and refuse to comply with an Order to Report for Induction in that he refused to comply with instructions, rules and procedures prescribed for registrant processing at the Armed Forces Examining and Entrance Station, 341 North Milwaukee Street, Milwaukee, Wisconsin, as required by SSS Form No. 252, Order To Report For Induction; all in violation of Section 462, Title 50 Appendix, United States Code of Laws.”
Sorrell insists that it is impossible to determine from the indictment what particular instructions, rules or procedures he was charged with violating. The rules and regulations for registrant processing at the Armed Forces Examining and Entrance Station, found in Army Regulation, AR 601-270, are lengthy and detailed. Rule 7(c), Fed. Rules Crim.Proc., requires that an indictment “shall be a plain, concise and definite written statement of the essential facts constituting the offense charged.” Although “the language of the statute may be used in the general description of an offense, ... it must be accompanied with such a statement of the facts and circumstances as will inform the accused of the specific offense, coming under the general description, with which he is charged.” Russell v. United States, 369 U.S. 749, 765, 82 S.Ct. 1038, 1048, 8 L.Ed.2d 240 (1962); United States v. Hess, 124 U.S. 483, 487, 8 S.Ct. 571, 31 L.Ed. 516 (1888).
A similar indictment was held in United States v. Farinas, 299 F.Supp. 852, 854 (S.D.N.Y.1969), to be fatally defective, the court finding that the indictment fell “below the minimum standard of specificity in respect of the requirement of reasonable notice.” The district judge in the present case attempted to distinguish Farinas on the ground that the indictment under attack here charged the defendant not only with refusing to perform some unspecified duty but also with wilfully failing to comply with an order to report for induction in so refusing to comply with instructions, rules and procedures at the Examining Station. We fail to see any distinction. The indictment did not charge the defendant with failing to report for induction; it charged him with failing to obey rules and regulations at the examining station. We conclude that the indictment failed to apprise the defendant of the charges against which he had to defend with reasonable certainty. Defendant’s motion to dismiss the indictment should therefore have been granted.
II
We believe that Sorrell’s conviction would have to be reversed, even in the absence of the faulty indictment, on grounds that the government presented insufficient evidence of guilt of the offense charged. The evidence introduced by the government consisted in Sorrell’s Selective Service File and the testimony of Thomas N. Key, Assistant Processing Officer at the Milwaukee Examining Station, to which the defendant reported for induction.
Items 30 and 31 of the Selective Service File are, respectively, a form entitled “Report of Medical History” and a form entitled “Report of Medical Examination.” Each'form bears the type-written date April 17, 1969. On the back of the first form is the written statement “refuses to give medical history,” along with the signature of a Mare Erickson. The same signature appears on the second form, accompanying the statement that the defendant refuses to submit to a physical examination. This form bears a second notation, “Refuses to have A & P,” together with what appear to be the initials “TR.” There is also a stamp stating that no disqualifying defects or communicable diseases were noted on October 9, 1969. The government did not call Captain Erickson as a witness.
The only additional documentary evidence submitted on this issue was a letter from Lieutenant Key to the Dane County Transfer Board, Selective Service System, Madison, Wisconsin, dated October 10, 1969, stating that the defendant on October 9, 1969, “refused to comply with instructions, rules and procedures prescribed for registrant processing; individual refused to take part in all processing.”
It is readily apparent that, with the possible exception of the fact that Lieutenant Key testified at the trial, the evidence in this case is as inadequate as the documentary evidence held insufficient in our recent decision in United States y. Webb, 467 F.2d 1041 (7th Cir. 1972). The evidence in that case consisted in a letter sent to the United States Attorney stating that the named defendant had refused to submit to induction. The documentary evidence in the instant case consists in a letter written by Lieutenant Key stating that the defendant had refused to follow all the rules necessary for processing, plus notations on two medical forms, all but one of which bear a date different from the October 9, 1969, date on which the alleged violations occurred. The only notation bearing the appropriate date states that no physical defects were observed and bears no signature at all, unless the letters “TR” were so intended. There was, therefore, simply no reliable evidence of sufficient probative value upon which to base Sorrell’s conviction.
The government argues, however, that this case is distinguishable from Webb because the writer of the letter stating that the defendant had refused to comply with registration procedures, Lieutenant Key, testified at trial. The record does not support this contention. Key testified that while a letter such as the one mailed under his name would have been sent if a registrant “refused to cooperate with the procedure set forth by the Induction Center,” he had no recollection of whether he had ever seen the defendant before and had no personal knowledge of whether the infractions set forth in the letter had in fact occurred.
We conclude that Sorrell’s conviction was based on insufficient probative evidence and that the indictment under which he was charged was so vague that it failed to reasonably apprise him of the charges against which he was required to defend.
Reversed.
