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:
UNITED STATES of America, Plaintiff-Appellee, v. David MENDIA, Defendant-Appellant.
No. 83-5126.
United States Court of Appeals, Ninth Circuit.
Argued and Submitted Dec. 5, 1983.
Decided April 27, 1984.
Hector Salitrero, Asst. U.S. Atty., San Diego, Cal., for plaintiff-appellee.
Gerald Blank, San Diego, Cal., for defendant-appellant.
Before GOODWIN, WALLACE and TANG, Circuit Judges.
TANG, Circuit Judge:
Appellant David Mendia appeals his conviction for possession with intent to distribute heroin in violation of 21 U.S.C. § 841(a)(1) and § 846. He challenges the trial court’s ruling that the seizure of evidence from the trunk of a third party’s automobile did not invade his fourth amendment rights and was admissible against him. He also claims he was denied a fair trial because the district court refused to grant immunity to a prospective defense witness whom appellant alleges would have offered testimony sufficient to show that he retained a reasonable expectation of privacy in the contents of the third party’s trunk such that the seizure violated his fourth amendment rights. We affirm.
Background
As part of a surveillance operation in April of 1982, Drug Enforcement Administration (DEA) agents followed the appellant as he left the apartment of a suspected drug dealer. Agents followed the appellant to a shopping center where he was seen entering a camera shop and then an adjacent bar. Inside the bar, appellant made several phone calls. About three hours later, Michael Leon Bronk met the appellant in the bar. Bronk and the appellant came out of the bar. While Bronk waited near the appellant’s car, the appellant reentered the bar and returned two minutes later. Bronk was observed opening the trunk of his car and throwing a light colored object inside. Bronk then got in the car and drove away.
DEA agents requested sheriffs officers to stop Bronk’s vehicle. After stopping Bronk, the sheriffs opened the trunk and found 20 ounces of heroin.
The appellant was charged with conspiracy to possess with intent to distribute a controlled substance under 21 U.S.C. §§ 841(a)(1) and 846. At trial, appellant sought to have the heroin suppressed, but the district court denied the motion, concluding that the appellant lacked standing to challenge the search of Bronk’s vehicle. Appellant’s motion to secure judicial immunity for Bronk was also denied.
Fourth Amendment
Mendia appeals the district court’s ruling that he demonstrated no violation of his fourth amendment rights in the search and seizure from Bronk’s vehicle because he had abandoned any reasonable expectation of privacy in the heroin by turning it over to Bronk. To show a seizure violated his fourth amendment rights, a criminal defendant must demonstrate a reasonable expectation of privacy in the item seized. United States v. Perez, 644 F.2d 1299, 1303 (9th Cir.1981). Abandonment of the seized item, however, may extinguish the defendant’s reasonable privacy expectations. See United States v. Perez, 689 F.2d 1336, 1338 (9th Cir.1982) (per curiam). The abandonment inquiry “is primarily a question of intent, and intent may be inferred from words, acts, and other objective facts.” United States v. Anderson, 663 F.2d 934, 938 (9th Cir.1981), quoting United States v. Jackson, 544 F.2d 407, 409 (9th Cir.1976). A trial court’s determination of abandonment is a factual issue and will not be reversed unless it is clearly erroneous. United States v. Kendall, 655 F.2d 199, 203 (9th Cir.), cert. denied, 455 U.S. 941, 102 S.Ct. 1434, 71 L.Ed.2d 652 (1981).
The trial court determined that the appellant had abandoned his reasonable expectations of privacy in the heroin by turning it over to Bronk and making no effort to follow Bronk after Bronk drove away with the heroin in his trunk. In United States v. Perez, 689 F.2d 1336, this court found three defendants had demonstrated a violation of their fourth amendment rights in the seizure of narcotics from the gas tank of a truck they did not own because they maintained a proprietary interest in the narcotics by having one defendant ride in the vehicle and the two others follow it. By keeping the truck under surveillance, the defendants “took reasonable precautions to maintain their privacy interest.” Id. at 1338. A similar element of control is lacking in this case. After giving the heroin to Bronk, the appellant made no effort to follow Bronk or maintain surveillance over the transportation of the heroin. The district court’s conclusion that the appellant had abandoned his reasonable expectation of privacy by relinquishing control of the heroin is not clearly erroneous.
Witness Immunity
The appellant contends, however, that testimony from Bronk could establish the existence of an arrangement to return the heroin to the appellant. Appellant suggests that this arrangement, when proven, would demonstrate that he maintained a privacy interest in the heroin even though he had completely relinquished physical control of the heroin after turning it over to Bronk. Thus, appellant claims that the district court’s refusal to grant immunity to Bronk effectively denied the appellant a fair trial.
What the appellant requests, however, is beyond the power of the district court to grant. “A defendant has no absolute right to elicit testimony from any witness, codefendant or not, whom he may desire.” United States v. Carman, 577 F.2d 556, 561 (9th Cir.1978). More importantly, however, the decision to grant immunity to prospective defense witnesses is left to the discretion of the executive branch. United States v. Alessio, 528 F.2d 1079 (9th Cir.), cert. denied, 426 U.S. 948, 96 S.Ct. 3167, 49 L.Ed.2d 1184 (1976). “To interpret the Fifth and Sixth Amendments as conferring on the defendant the power to demand immunity for co-defendants, potential co-defendants, or others whom the government might in its discretion wish to prosecute would unacceptably alter the historic role of the Executive Branch in criminal prosecutions.” Id. at 1082. Lacking the authority to foreclose executive branch discretion in this area, a district court has neither the power to grant use immunity to individuals whom the defendant seeks to call as witnesses, nor the power to force the government to grant such immunity. United States v. Richardson, 588 F.2d 1235, 1241 (9th Cir.1978); United States v. Benveniste, 564 F.2d 335, 339 n. 4 (9th Cir.1977); United States v. Jenkins, 470 F.2d 1061 (9th Cir.1972), cert. denied, 411 U.S. 920, 93 S.Ct. 1544, 36 L.Ed.2d 313 (1973). Cf. United States v. Lord, 711 F.2d 887 (9th Cir.1983) (propriety of dismissal when prosecutorial misconduct creates defense witness unavailability).
AFFIRMED.
