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 "private business and its executives". 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.

PER CURIAM.
This case presents the question of whether the Secretary of the Department of Health, Education and Welfare was authorized by 42 U.S.C. § 1395b-l to enter into an experimental contract for administration of Illinois Medicare Part B with a company that is not shown by the present record to be a “carrier” as defined by 42 U.S.C. § 1395u(f). Also presented is the question of whether the plaintiffs, two disappointed bidders, are barred from asserting their action challenging the award of the contract to another because they did not file it until after the award had been made.
The district court entered summary judgment for defendants, holding that the action was not timely under Airco, Inc. v. Energy Research and Development Administration, 528 F.2d 1294 (7th Cir. 1975), and, alternatively, that the statute permitted the Secretary to award the experimental contract to a non-carrier (and therefore the fact issue of whether the successful bidder was a carrier was immaterial). Health Care Service Corp. v. Califano, 466 F.Supp. 1190 (N.D.Ill.1979).
We disagree with the district court’s holding that Aireo bars this action. In that case the procurement authority ordered rebidding with changed specifications. The initially successful bidder sought neither timely administrative nor judicial review of the rebidding order but waited to challenge that order until another bidder had won in the rebidding. The court held, as an alternative ground, that the plaintiff had waived objections to the rebidding and, by its willingness to accept the change in specifications, that change as well. Here plaintiffs contend that they were unaware that the bidding was open to non-carriers and that one of the bidders was a non-carrier until after the bid award. Even if these contentions do not raise issues of fact, we think that extending the alternative ruling in Airco to the facts at bar is not warranted. The Airco plaintiff had a matured right as the successful bidder and was aggrieved if its contentions on the merits were correct. Plaintiffs here are not similarly situated. A general rule that a bidder must assert objections to a bid before the award to avoid waiver would encourage objections that time and events may solve without appeal to higher administrative authority or to the courts and would tend to cause unnecessary delays in procurement.
We do agree, however, with the district court’s holding on the merits and adopt that part of the court’s opinion that holds that the Secretary had authority to award the contract to a non-carrier. 466 F.Siipp. at 1194 (last seven lines) — 1197 (first 24 lines). We add only that the interpretation of a complex statute such as the Medicare Act by the administrative officer charged with the responsibility of administering it is entitled to considerable deference and, if reasonable, is not to be rejected by a court merely because another interpretation may also be reasonable. See American Meat Institute v. EPA, 526 F.2d 442, 449-450 (7th Cir. 1975).
The judgment is therefore affirmed.
Affirmed.
. Claims asserted in the district court concerning the methodology employed by defendants in assessing the bid proposals are not pursued on appeal.
. The court’s conclusion to this effect was challenged on rehearing. In a footnote the court found the record inadequate to support this challenge but stated that “[t]he failure to file a timely informal protest was . . . merely an alternative ground” on which the court did not need to rely.
