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.

Opinion:
INTERSTATE ENGINEERING CO., Inc., et al. v. DISTRICT OF COLUMBIA, to Use of ALCO PRODUCTS, Inc.
No. 7435.
United States Court of Appeals for tlie District of Columbia.
Argued March 7, 1940.
Decided April 29, 1940.
Robert E. Lynch, of Washington, D. C., for appellants.
Charles Dickerman Williams, of New York City, and Richard H. Wilmer and Douglas L. Hatch, both of Washington, D. C., for appellee.
Before GRONER, Chief Justice, and MILLER and VINSON, Associate Justices.
GRONER, C. J.
This is an action brought in the District Court by Aleo Products, Incorporated (ap-pellee), against Interstate Engineering Company, Inc., and New Amsterdam Casualty Company, its surety (appellants), for the balance of the purchase price of steel pipe sold and delivered by Aleo to Interstate for use in a public improvement in the District of Columbia, pursuant to a proposal made by Aleo June 14, 1934, and confirmed September 20, 1934. The agreement provided for payment in full “not later than 200 days from date of'first shipment”. Shipments began November 20, 1934, and were completed in December, 1934. Interstate admitted receipt of the pipe, but sought to diminish the amount due therefor by claiming damages caused by delay in delivery. The lower court instructed the jury to find for the plaintiff in the full amount of the claim, with interest.
On this appeal, Interstate and the surety company charge error in the admission by the court in evidence of a series of letters from Aleo showing demands for payment and from Interstate in acknowledgment of tlie indebtedness. Also in the refusal of the court to direct a verdict in favor of Interstate, and in instructing the jury in favor of Aleo.
The grounds of Interstate’s objections to the. letters do not appear in the record, but we have examined the correspondence and are of opinion that all of it was relevant and properly a part of plaintiff’s case. In addition to this, the correspondence showed express admissions by Interstate relevant and proper in denial of its counterclaim.
Appellants’ main argument on this appeal is that the court erred in directing a verdict for appellee “on the theory of an account stated”. The basis of this argument is that the court, in directing a verdict for the plaintiff, said: “ * * * the defendant accepted the bills which the plaintiff rendered for the materials shipped, and agreed to pay those hills in full, making no claim or objection to them; so that this defendant must be treated as having assented to the bills rendered, or the bills rendered ha ve become, as we say, an account stated, not subject to objection later.”
Appellants insist the theory that the suit was brought on an account stated is not responsive to the pleadings. I f that was ihe theory of the decision, undoubtedly appellants are correct, for an account stated is treated as a new contract and is not necessarily conclusive of claims not intended to be. covered. Willis ton on Contracts (2d Ed.), §§ 1862, 1864; Stearns Company v. United States, 291 U.S. 54, 65, 54 S.Ct. 325, 78 L.Ed. 647; Chinn v. Lewin, 57 App.D.C. 16, 16 F.2d 512, 40 A.L.R. 1480. But we think the court’s language was not intended in a technical sense but merely as a method of conveying to the jury the idea that defendant, having received the pipe and thereafter without objection having agreed to pay for it, was presumed to have assented 5o the correctness of the amount due and waived the defenses which nearly two years later it attempted to set up. The use of the words — account stated — was merely a figure of speech which, in deference to the jury, the court thought they would likely understand as impelling his action in talcing the case from them.
The record shows the shipments of pipe began in November, 1934, and were completed in December, 1934 (except as to an “extra”, subsequently ordered). Plaintiff wrote defendant on January 10, 1935, enclosing statement of account and asking when payment might be expected. Defendant answered this communication January 16, acknowledging the correctness of the account and advising that it expected payment from the District of Columbia within 60 days. Later, on June 4, 1935, defendant wrote plaintiff:
“Just as soon as the line has been tested and payment made to us, we will forward you payment in full for this material.
“Thanking you for your co-operation in this matter, we are * * * ”
Again, on June 17, 1936, defendant wrote:
“We are exceedingly pleased to herewith attach Government check #474,567, in the amount of $33,350.35, endorsed to your order to apply on our account.
“We are vigorously pressing our claim against the District and we anticipate an early conclusion thereof. The balance of the account will be paid at said time.
“In closing, permit us to say that we are very appreciative of the patience which you have displayed.”
At no time during' the eighteen months’ correspondence did defendant or its surety intimate the .existence of any counterclaim for damages by delay in receipt of the pipe. While the authorities are not entirely uniform as to what conduct will amount to a waiver of counterclaim for damages, Williston on Contracts, § 704, we are of opinion that the absence of any protest for a period of almost two years, coupled with two written promises in the interim to pay in full, and a substantial payment expressly stated to be “on our account”, are sufficient to show a waiver as a matter of law. Kalamazoo Ice Co. v. Gerber, 6 Cir., 4 F.2d 235; Reid v. Field, 83 Va. 26, 1 S.E. 395; White v. T. W. Little Co., 118 Wash. 582, 204 P. 186; Minneapolis Threshing-Machine Co. v. Hutchins, 65 Minn. 89, 67 N.W. 807; Roby v. Reynolds, 65 Hun 486, 20 N.Y.S. 386. Cf. Restatement of Contracts, § 412. On this branch of the case, we have no doubt the holding of the District Court was correct.
This leaves for consideration only the calculation of interest. Appellee admits an inaccuracy of $13 in the computation, and agrees that the court may direct a remittitur as to this excess. With this exception, the computation was correct under the rule in Story v. Livingston, 13 Pet. 359, 10 L.Ed. 200. The judgment of the lower court is, therefore, affirmed, subject to the remittitur mentioned above.
Affirmed.
The question of waiver is now controlled by D.C.Code (Supp. Y), Tit. II, § 105), which is § 49 of tlie Uniform Sales Act, enacted for the District of Columbia in 1987, after the transactions involved in this case. 50 Stat. 29.
