S.Ct. at 2785, the challenged private actions. Indeed, as the government points out, Congress conditioned funding for the Contras on a certification by the President that the “Nicaraguan democratic resistance groups receiving assistance ... have agreed to and are beginning to implement ... the elimination of human rights abuses.” Pub.L.No. 99-500, § 101(k), 100 Stat. 1783, 1783-802 (1986). We think Blum thus forecloses any conclusion that, solely because of United States support, the Contras’ actions against appellants constitute “state action.”
In Rendell-Baker v. Kohn, 457 U.S. 830, 102 S.Ct. 2764, 73 L.Ed.2d 418 (1982), decided the same day as Blum, the Court reviewed factors other than government funding and regulation that might convert private activities into “state action.” None of these other factors is present in this case. For example, where the government has delegated a public function that is “traditionally the exclusive prerogative of the State,” Jackson v. Metropolitan Edison Co., 419 U.S. 345, 353, 95 S.Ct. 449, 454, 42 L.Ed.2d 477 (1974), the government may be responsible for seeing that the function is carried out lawfully. In addition, a government that enjoys a “symbiotic relationship” with a private entity may be liable for its wrongdoing. For example, in Burton v. Wilmington Parking Auth., 365 U.S. 715, 81 S.Ct. 856, 6 L.Ed.2d 45 (1961), a restaurant that rented space in a commercial building owned by the city refused to serve black customers. The Court found that the “profits earned by discrimination not only contribute to, but also are indispensable elements in, the financial success of a governmental agency.” Id. at 724, 81 S.Ct. at 861.
The “public function” and “symbiotic relationship” tests for state action perform awkwardly, at best, in the realm of foreign relations. But to the extent these principles can be adapted to the facts of the present case, they reveal no sign of state action. Support for a rebel group in a foreign country scarcely constitutes delegation of a “public function” that would otherwise be performed by the United States. Nor, under the “symbiotic relationship” test, can it be argued that the United States government benefits from the Contras’ alleged attacks on American citizens.
The Rendell-Baker Court noted one other factor that can support a finding of state action by private parties. In a few cases, government officials have helped private parties carry out the constitutionally suspect action. Thus, in Lugar v. Edmondson Oil Co., 457 U.S. 922, 102 S.Ct. 2744, 73 L.Ed.2d 482 (1982), a creditor attached plaintiff’s property without due process of law. Because a local sheriff executed the writ of attachment, the Court held that “a private party’s joint participation with state officials in the seizure of disputed property is sufficient to characterize that party as a ‘state actor’ for purposes of the Fourteenth Amendment.” Id. at 941, 102 S.Ct. at 2755. As we have already noted, appellants make no such claims of “joint participation” by United States personnel in the Contras’ attacks on Americans in Nicaragua.
b. The absence of a constitutional tort
A court’s determination that privately inflicted harm does not constitute “state action” would ordinarily conclude the inquiry as to whether the government itself violated the Constitution. Appellants seek to avoid that result, however, by sidestepping the state action issue. Rather than argue about the governmental character of the Contras’ activities, appellants focus on the government’s own action— namely, Congress’ decision to fund the Contras. It is this action, according to appellants, that “directly, foreseeably, and necessarily increases the risk to the lives and security of U.S. citizens.” Brief for Appellants at 16. Appellants thus raise the prospect that the government has committed tortious conduct by facilitating — or by failing to prevent — the Contras’ infliction of harm. The key question, however, is whether this putatively tortious conduct by the government could rise to the level of a constitutional tort that violates due process. Most torts do not rise to that level.
