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 OF THE COURT
VAN DUSEN, Circuit Judge.
This appeal is taken from a District Court order denying relator’s petition for a writ of habeas corpus. He has been in the custody of the United States Army since his induction on July 16, 1968.
Most of the facts of this case were stipulated prior to argument before this court, and the stipulation was approved pursuant to Rule 10(e) of the Federal Rules of Appellate Procedure. After conviction on September 23, 1966, for failing to submit to induction into the Army, under the Selective Service Act of 1948, Title 1, § 12, as amended, 50 U. S.C. App. § 462(b) (6) (1968), relator was sentenced to a three-year prison term. On February 1, 1967, relator petitioned the Attorney General for parole into the custody of the Armed Forces of the United States, pursuant to Executive Order 11,325, 32 C.F.R. § 1643 (1967). That Order provides that anyone convicted of a violation of the Selective Service laws may be granted a parole into the custody of the Armed Forces of the United States by the Attorney General “if it is compatible with the public interest and the enforcement of the Military Selective Service Act of 1967.” 32 C.F.R. § 1643.2. Application to the Attorney General must be made by the prisoner, and he must consent to induction into the Armed Forces. Id. § 1643.5(c) (1). If the parolee is not inducted into the Armed Forces, he must be returned to the correctional institution to complete his sentence. Id. § 1643.7. He is discharged from further confinement and supervision for the violation of the Selective Service laws upon his completion of his military service under honorable conditions. Id. § 1643.9.
The February 1, 1967, petition and several subsequent, similar petitions prior to July 16, 1968, were denied because of an embezzlement indictment containing three counts, which had been outstanding against relator since July 6, 1966. Because of the representations of relator that the pending indictment had been dismissed, he was paroled into the custody of the United States Army on July 16, 1968, pursuant to Executive Order 11,325. Consistent with these representations, relator failed to list the outstanding indictment on two induction questionnaires and he affirmatively listed the indictment as dismissed on his Statement of Personal History taken six days after his induction at Fort Jackson, South Carolina. The relator and all Government officials involved believed that the indictment had been dismissed before relator’s induction.
The indictment was not in fact dismissed until October 8, 1968. The dismissal was probably based'on a request by relator’s former employer that the charges be dismissed on the fact that restitution was being made to the employer, and possibly on relator’s induction into the Army.
Relator now challenges the July 1968 induction because of the outstanding indictment, relying on Army Regulation 601-270(23) (d), which provides:
“Criminal charges filed and pending. Men who have criminal charges filed and pending against them alleging a violation of a State, Federal, or territorial statute are unacceptable. * * * Waivers will not be granted in these instances.”
Relying on the alleged principle that a Government agency is required to follow its own regulations, relator reasons that induction was illegal. See Oshatz v. United States, 404 F.2d 9 (9th Cir. 1968); Hammond v. Lenfest, 398 F.2d 705, 715 (2nd Cir. 1968); Briggs v. United States, 397 F.2d 370 (9th Cir. 1968); Roberts v. Vance, 119 U.S.App. D.C. 367, 343 F.2d 236 (1964); Cherne-koff v. United States, 219 F.2d 721, 725 (9th Cir. 1955). Alternatively, relator argues that the Army was required to investigate the alleged dismissal of the pending charges before inducting him. The Government argues that the Army Regulations are for the Army’s internal convenience alone, and therefore cannot be used by an inductee to challenge his induction. See United States v. Brooks, printed at 415 F.2d 507-510 (M.D.Tenn. 1968) , aff’d. 415 F.2d 502 (6th Cir. 1969) . The Government also argues that the federal courts are without jurisdiction to grant habeas corpus relief to an inductee alleging illegal induction until such time as he has pursued administrative remedies within the Army to secure his release. See Craycroft v. Ferrall, 408 F.2d 587 (9th Cir. 1969). But see United States ex rel. Caputo v. Sharp, 282 F.Supp. 362 (E.D.Pa. 1968); cf. Powers v. Powers, 400 F.2d 438 (5th Cir. 1968). Because we feel that relator, under the unusual circumstances of this case, is estopped from challenging his induction on the basis of the pending criminal charges, we need not reach these issues.
Several applications of relator for parole under Executive Order 11,325 were denied because of his pending indictment. Prior to the induction he challenges here, he represented to the Government that the indictment had been dismissed; the Attorney General relied on this representation in granting his application for parole, and his draft board and the Army relied on this representation in accepting him for induction. Had relator contradicted this representation at any time, he most probably would have been refused induction (despite his consent) and returned to prison. Having represented that the indictment was dismissed, he is now es-topped from denying that fact. See, e. g., Reliance Molded Plastics, Inc. v. Jiffy Products, 215 F.Supp. 402, 413 (D. N.J. 1963), aff’d. per curiam 337 F.2d 857 (3rd Cir. 1964); Vigdor v. Young, 102 U.S.App.D.C. 414, 254 F.2d 333, cert. den. 358 U.S. 854, 79 S.Ct. 84, 3 L. Ed.2d 88 (1958); cf. Nickerson v. United States, 391 F.2d 760, 763 (10th Cir.), cert. den. 392 U.S. 907, 88 S.Ct. 2061, 20 L.Ed.2d 1366 (1968). That his representation was innocently made in no way alters this result. E. g., Countway v. Commissioner of Internal Revenue, 127 F.2d 69 (1st Cir. 1942).
The order of the District Court will be affirmed.
. Relator was convicted in 1966 for a violation of the Selective Service Act of 1948. According to its terms, Executive Order 11,325 applies only to persons convicted for violating the Military Selective Service Act of 1967. Since neither relator nor the Government has suggested that the parole was therefore unauthorized, we need not consider the effect of this discrepancy.
. Paragraph 7 of the Stipulation provides: “The Attorney General relied on appellant’s representations that the indictments had been dismissed in granting appellant’s [relator’s] parole into the custody of the Army, and the Army relied on appellant’s representations in accepting him for induction.”
. In addition to a Record of Induction in which relator failed to list the pending indictment, relator also filled out an Eligibility Questionnaire prior to his induction on July 16, 1968. This document was signed by relator and provided:
“I understand the information I have furnished is to be used in determining my eligibility for military service and it will be treated as privileged information. * * * I have not been given any advice by induction personnel to conceal any information regarding the entries I have made on this form * * *. I understand that this is my last opportunity to reveal this information. I certify that the answers to the above questions are my own, they are true and correct and I have furnished complete details concerning all answers marked ‘yes’.”
Relator answered the questions concerning prior convictions and pending actions “yes,” but failed to list the pending state court indictment for embezzlement, either as outstanding or dismissed.
. Under Army Regulation 601-270(3-9), a registrant is required to obtain a moral waiver from the Armed Forces Moral Waiver Determination Board if he has been convicted of a crime. Nevertheless, “Moral waivers will not be forwarded to the Armed Forces Moral Waiver Determination Board where the results of the investigation made * * * show that the criminal charges against the individual have been dismissed * * * without an adjudication of guilt. However, these cases will be thoroughly investigated before determination is made that no convictions * * * exist and to determine whether [any criminal charges are pending].”
. Approximately 20 letters prior to July 16, 1968, from relator to the Judge who had sentenced him for failing to submit to induction indicated relator’s realization that his parole under Executive Order 11,325 was being held up due to the pending state court indictment.
