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 "the federal government, its agencies, and officials". 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.

Appeal from a deeree in the Supreme Court of the District dismissing, after hearing, plaintiff’s bill (filed May 11, 1929), praying that premises No. 218 Indiana Avenue N.W. (lot 14, in Smith So Marr’s subdivision of square south of square 572) be impressed with a trust for her benefit in the sum of $6,500, less $1,127.57.
The material facts found by the court below are substantially as follows: On May 10, 1927, plaintiff, being the owner of the premises in question, entered into a contract of sale with the defendant Francis A. Crawford through a Mr. Lewis as Crawford’s agent. Under the terms of the contract, the purchase price of the property was to be $500 cash and a deferred purchase-money trust in the sum of $6,500 as a second trust secured on the property. In closing the transaction, Crawford delivered to plaintiff in a sealed envelope a note secured by a second trust on lot 34, square 2692, fraudulently representing that the note was secured on the property sold, i. e., 218 Indiana avenue, as agreed. Plaintiff signed all necessary papers, “and at the time she signed the same she noted that there was a difference between the lot and square on the said papers and did nothing to change the same.” The property on which the note was secured was incumbered by a first deed of trust in excess of its value, and was shortly thereafter sold at auction under the first trust.
A day or two after signing the papers, plaintiff had actual knowledge that the second trust given to her was not on her premises at 218 Indiana avenue. Thereupon plaintiff retained counsel and authorized institution of necessary proceedings to protect her rights; but no proceedings were filed until November 21, 1927, when a bill in equity was filed to rescind the contract and cancel the deed. (What happened under that suit does not appear.) Meanwhile, on July 13, 1927, Arthur L. Murray (to whom evidently the property had been deeded) conveyed the premises by deed of trust to Samuel A. Drury and James P. Nicholson, as trustees, to secure the loan of $4,000. At the time the trustees accepted the deed, they had no notice, either actual or construe^ tive, of any outstanding claims or equities of the plaintiff. Before the trust was executed and the loan made, the question of title was referred to the District Title Company for examination.
Thereafter, on the 27th of March, 1928, because of default in payment by Murray, the trustees sold the property at public auction to Charles F. Ruppert for $5,850. Pri- or to the sale Nicholson, trustee, saw plaintiff in possession of the premises. The deed, at Ruppert’s direction, was made to his wife, Annie C. Ruppert. At the time of the sale, Ruppert did not have notice, either actual or constructive, of any outstanding equitable claims of the plaintiff.. Plaintiff was in actual, open, visible possession of the premises from November 16, 1920, until the latter part of 1928.
The court below found that the trustees, Drury and Nicholson, by virtue of the deed of trust from Murray, took legal title to the premises, 218 Indiana avenue, as bona fide purchasers for value; that Ruppert, by purchasing from Drury and Nicholson, took the property free from equitable claims or demands of the plaintiff.
The court'directed the payment to plaintiff of $1,127.57, the amount over and above expenses of the sale under the first trust on the premises in question. Counsel for plaintiff in their brief acknowledge' the receipt of that amount.
A decree pro confesso was taken as to the defendants Crawford and Murray.
The question in this appeal is whether the mere possession of premises, 218 Indiana avenue, by plaintiff, after she had made a conveyance of the property, constituted constructive notice to subsequent incumbrancers and purchasers acting in good faith.
It is the general rule that actual, visible, and unequivocal possession of real estate inconsistent with the record title and under an apparent claim of ownership is notice to purchasers of whatever interest the person actually in possession has in the fee, whether such interest be legal or equitable in its nature, and of all the facts which the prospective purchaser might have learned by due inquiry. Chillemi v. Pennsylvania Rubber Co., 58 App. D. C. 394, 31 F.(2d) 638; Kirby v. Tallmadge, 160 U. S. 379, 16 S. Ct. 349, 40 L. Ed. 463.
An exception to the general rule is recognized where a vendor remains for a time in possession after giving a fee-simple deed, with covenants, which he permits to be recorded. The object of the general rule is to protect one in possession from acts, of others who do riot derive their title from him; not to protect, him against his own acts, and especially against his own deed. Bloomer v. Henderson, 8 Mich. 395, 77 Am. Dec. 453; Van Keuren v. Central R. Co., 38 N. J. Law, 165; Strong v. Efficiency Apt. Corp., 159 Tenn. 337, 17 S.W.(2d) 1, 19 S.W.(2d) 273; Wicklein v. Kidd, 149 Md. 412, 131 A. 780.
Another reason for this exception to the rule is the equitable maxim that, where one of two innocent persons must suffer by the acts of a third, he "who has enabled such third person to occasion the loss must sustain it. National Safe Deposit, etc., Co. v. Hibbs, 229 U. S. 391, 33 S. Ct. 818, 57 L. Ed. 1248; Pirkey v. Williams, 45 App. D. C. 590, 599; Moore v. Moore, 47 App. D. C. 23, 28; Gray v. Jacobsen, 56 App. D. C. 353, 13 F.(2d) 959, 48 A. L. R. 583.
In the present case, plaintiff, when she executed her deed to Crawford and the deed was recorded, declared to the world that she had conveyed all her interest to Crawford. When, therefore, Drury and Nicholson, as trustees, accepted the deed of trust from Murray, the record owner, to secure the loan of $4,000, the mere fact that Mrs. McKinley had remained in possession of the property did not charge the trustees with notice of her equities.
There is another ground on which the decree may be sustained. The court below has found that, within a day or so after signing the papers on May 10, 1927, plaintiff had actual knowledge of the fraud which had been practiced upon her, and yet no suit was filed until November 21st, more than six months thereafter. Meanwhile, on July 13th, the trustees, Drury and Nicholson, had accepted the deed of trust to secure the loan of $4,000 on the property. In so far as innocent third parties were involved, plaintiff was lacking in diligence. She had every reason to expect that a man who would deceive her in the manner in which Crawford did would attempt to deceive others. Therefore, for the protection of innocent third parties, it was her duty to move with the utmost expedition. Holman v. Ryon, 61 App. D. C. 10, 56 F.(2d) 307; R. Harris & Co. v. Weller, 52 App. D. C. 6, 12, 280 F. 980.
Decree affirmed, with costs.
Affirmed.
