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:
STANFORD v. PENNSYLVANIA R. CO.
No. 9681.
United States Court of Appeals Seventh Circuit.
Dec. 11, 1948.
John J. Enright, of Chicago, 111., and Charles F. Scanlon and Ray J. McGowan, both of Akron, Ohio, for appellant.
Theodore Schmidt, P. J. Cronin, Charles F. White, and Herbert C. De Young, all of Chicago, 111., for appellee..
Before KERNER and SPARKS, Circuit Judges, and LINDLEY, District Judge.
KERNER, Circuit Judge.
This was a suit in which plaintiff claimed damages under the Federal Employers’ Liability Act, 45 U.S.C.A. § 51 et seq., for the death of her husband, Dona-ld G. Stanford, while in defendant’s employ. The cause was tried to a jury. The jury found against defendant and returned a verdict for plaintiff .for $9,000. Defendant moved the court to set aside the verdict and enter judgment in accordance with its motion for a directed verdict in its favor. The trial judge set asi-de the verdict and entered judgment notwithstanding the verdict in favor of defendant.
The complaint was based upon the charge that defendant had negligently moved a locomotive at a time when plaintiff’s decedent was attempting to put water into the tender of the locomotive. It appeared that a water plug had been pinned again-st Stanford’s stomach, causing injuries from which he died. There was evidence that the fall spout of the water plug was bent and that the plug was closed by the impact, but there were no eye witnesses to show definitely the actual occurrence -at and just prior to the time that Stanford was crushed.
The trial judge was of the opinion that “The only reasonable explanation of the accident i-s that Stanford upon giving the •signal and before the engine stopped moving, stepped between the plug and the coal slope, placing himself in -a position of danger and that his death was not the result of any negligence on the part of the engineer.”
PlaintifF-s theory is that in order to crush Stanford the -train must have continued to move after th-e stop signal was given, because at the time t-h-e stop -signal was given Stanford had not been injured, but was standing in front and to the north of the water plug or spout. On the other hand, defendant contends that there is no evidence tending to -show that defendant was guilty of any negligence. Its theory is that Stanford, upon giving the signal and before the train stopped moving, stepped between t-h-e plug and the coal slope, grabbed t-he plug either before the train had entirely stopped or pulled it with -such force that the spout hit him.
Thus there is presented th-e question of whether -there was any -evidence to -support the jury’s finding that defendant negligently moved th-e engine at a time w-hen Stanford was attempting to pu-t water into the tender. If -there was any evidence which, together with a-11 the reasonable -inferences that might -be drawn the-refirom, supports plaintiff’s case, the trial judge erred in substituting his conclusions for those of t-he jury, -since the jury i-s -th-e tribunal to decide that type o.f -issue. Bailey v. Central Vermont Ry., 319 U.S. 350, 353, 63 S.Ct. 1062, 87 L.Ed. 1444; Tennant v. Peoria & P. U. Ry. Co., 321 U.S. 29, 64 S.Ct. 409, 88 L.Ed. 520; and Myers v. Reading Co., 331 U.S. 477, 67 S.Ct. 1334, 91 L.Ed. 1615. Only a -complete absence of probative facts -to support the conclusions reached would justify a court -to substitute i-t-s -conclusions for those of the ju-ry. Lavender v. Kurn, 327 U.S. 645, 66 S.Ct. 740, 90 L.Ed. 916. This is so because the choice of -conflicting versions of the way t-he accident happened, -the decision as to which witnes-s is telling the truth, and -the inferences to be drawn from uncontroverte-d -a-s well as c-on-t-roverted facts, are questions -for the jury. Once there is a reasonable basis for concluding that there Was negligence which caused the injury, it is irrelevant that -fair minded men might reach a different conclusion. Otherwise it would be an invasion of the jury’s function for the trial judge to draw contrary inferences or to conclude that a different conclusion would be more reasonable. Ellis v. Union Pacific R. Co., 329 U.S. 649, 653, 67 S.Ct. 598, 91 L.Ed. 572.
Stanford was -a locomotive fireman on board -the -engine -of an interstate passenger train consisting of an -engine, tender, -and -eight coaches. For -the purpose of taking -on water, th-e engine stopped at a water plug, consisting of -a standpipe, an ■extension pipe and fall pipe, in defendant’s East Con-way Yards, Pennsylvania. Defendant’s -tracks at this point run in a general -easterly and westerly -direction.c The water plug wa-s located to the south of -the tracks u-pon which this -engine was 'being operated, headed east. Stanford got down from th-e engine, unlatc-h-ed -the plug, turned it over to th-e tender, and then got up on. the tender. Located on -the tender, immediately to the rear -of th-e coal -loft or slope, was a brakeman’s -cabin about 4% feet in height. Stailfo-rd, for -the purpose of putting water into the manhole located on the extreme rear -end of -the -tender, swung the extension pipe of the plug from -the south to the north, but when the pipe would not -clear the cabin, he signaled the 'engineer, sitting sidewise -on a -seat on the south side of the cab of the engine with his back toward Stanford, to move the engine from 24 to 36 inches in order that -the plug might be in a position to spot the plug over the manhole. From certain photographs -showing the tender, the cabin and th-e water plug, if appears that the -only way the plug -cou-ld -clear the cabin would be to s-wing th-e plug -clear of the engine and move the engine forward.
The engineer testified that after receiving Stanford’s signal he moved the -engine back about two feet or perhaps -a little more than -that, and that when it was far enough he looked up and -saw Stanford ■standing in .front and to the north of the plug; that Stanford waved his arm to stop the engine, and hollered “That will do”; that thereupon he put on the air valve with the independent brake and stopped the engine; and that when he next -looked up -he -saw Stanford’s hands back -up over the coal slope; that he did no-t se-e Stanford change his position from -the time Stanford Called out “That will do” -and that he did not see Stanford when he was in the act of stopping the .train; that he immediately went up to see what the trouble was and found Stanford pinned between the coal slope and the plug. To this evidence must be added the presumption that Stanford was in the exercise of due care for his own safety at the time he was crushed. Tennant v. Peoria & P. U. Ry. Co., supra; and Chicago & N. W. Ry. Co. v. Grauel, 8 Cir., 160 F.2d 820, 821.
We think, after applying the principles enunciated in the cases cited above to the facts in our case, that there was evidence upon which the jury could have found negligence on the part of defendant which contributed, in whole or in pant, to Stanford’s death, and since there was an evidentiary basis .for the jury’s verdict, the jury was free to discard or disbelieve whatever facts were inconsistent with its conclusions, Lavender v. Kurn, supra, 327 U.S. 645, 653, 66 S.Ct. 740, 90 L.Ed. 916; and that .the court erred in substituting its conclusions .for those of the jury. Accordingly, the judgment of the District Court is reversed and the cause is remanded for further proceedings not inconsistent with this-opinion.
Reversed and remanded.
