Task: songer_numappel

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.
Your specific task is to determine the total number of appellants in the case. 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.
In a trial for violation of the narcotic laws, agents of the Government were advised at seven o’clock, P. M., by an informer, that the appellants were to be at the informer’s house at approximately eight o’clock that night to deliver to him an ounce and a half of heroin. The agents proceeded to the informer’s house, where they concealed themselves. About half an hour later, two persons entered the house answering the description of them given to the agents by the informer. They were arrested and searched and, upon the person of one of them, there was found 405 grains of heroin, in violation of section 2553(a), Title 26, U.S.C.
At the trial, a motion to suppress the evidence was made on behalf of appellants on the ground that the search was made without a warrant and without probable cause to believe that the defendants were violating the law. The motion was denied, the evidence admitted, and a verdict of guilty returned by the court after waiver of a jury. The only issue relates to the reasonableness of the search.
Its validity must be determined by the reasonableness in the light of the particular facts and circumstances of the case. Brinegar v. United States, 338 U.S. 160, 69 S.Ct. 1302, 93 L.Ed. 1879; United States v. Rabinowitz, 339 U.S. 56, 70 S.Ct. 430, 94 L.Ed. 653; Carroll v. United States, 267 U.S. 132, 45 S.Ct. 280, 69 L.Ed. 543. The information received by the agents from the informer did not of itself warrant the arrest; but, when the defendants appeared at the home of the informer at approximately the time agreed upon and answered the description given to the agents, it imparted verity to the information received. The agents then were justified in believing that there was probable cause that a crime was being committed. It must be observed that the arrest was made and the search conducted at the home of the informer, and not at the home of the appellants. This distinguishes the case from that of Agnello v. United States, 269 U.S. 20, 46 S.Ct. 4, 70 L.Ed. 145, where it was said that there is no sanction in the decisions of the courts, federal or state, for the search of a private dwelling house without a warrant, and that absence of any judicial approval is persuasive authority that it is unlawful. This is on the ground that it is always feasible to obtain a search warrant for a search of the dwelling place of those accused. Worthington v. United States, 6 Cir., 166 F.2d 557, was similar: likewise, it involved the search of the home of the accused.
In this case, it was of course not feasible to obtain a search warrant before the time of delivery of the narcotics had arrived. The suggestion of counsel for the appellants that the agents should have waited until delivery was made to give reasonableness to the arrest is not persuasive, since no opportunity was given the agents upon such short notice to provide the informer with three hundred dollars of Government money with which to make the purchase.
Affirmed.
