delivered the opinion of the Court.
In this case we must decide whether the act of state doctrine bars a court in the United States from entertaining a cause of action that does not rest upon the asserted invalidity of an official act of a foreign sovereign, but that does require imputing to foreign officials an unlawful motivation (the obtaining of bribes) in the performance of such an official act.
I
The facts as alleged in respondent s complaint are as follows: In 1981, Harry Carpenter, who was then chairman of the board and chief executive officer of petitioner W. S. Kirkpatrick & Co., Inc. (Kirkpatrick), learned that the Republic of Nigeria was interested in contracting for the construction and equipment of an aeromedical center at Kaduna Air Force Base in Nigeria. He made arrangements with Benson “Tunde” Atóndele, a Nigerian citizen, whereby *402 Akindele would endeavor to secure the contract for Kirkpatrick. It was agreed that, in the event the contract was awarded to Kirkpatrick, Kirkpatrick would pay to two Panamanian entities controlled by Akindele a “commission” equal to 20% of the contract price, which would in turn be given as a bribe to officials of the Nigerian Government. In accordance with this plan, the contract was awarded to petitioner W. S. Kirkpatrick & Co., International (Kirkpatrick International), a wholly owned subsidiary of Kirkpatrick; Kirkpatrick paid the promised “commission” to the appointed Panamanian entities; and those funds were disbursed as bribes. All parties agree that Nigerian law prohibits both the payment and the receipt of bribes in connection with the award of a government contract.
Respondent Environmental Tectonics Corporation, International, an unsuccessful bidder for the Kaduna contract, learned of the 20% “commission” and brought the matter to the attention of the Nigerian Air Force and the United States Embassy in Lagos. Following an investigation by the Federal Bureau of Investigation, the United States Attorney for the District of New Jersey brought charges against both Kirkpatrick and Carpenter for violations of the Foreign Corrupt Practices Act of 1977, 91 Stat. 1495, as amended, 15 U. S. C. §78dd-l et seq., and both pleaded guilty.
Respondent then brought this civil action in the United States District Court for the District of New Jersey against Carpenter, Akindele, petitioners, and others, seeking damages under the Racketeer Influenced and Corrupt Organizations Act, 18 U. S. C. §1961 et seq., the Robinson-Patman Act, 49 Stat. 1526, 15 U. S. C. § 13 et seq., and the New Jersey Anti-Racketeering Act, N. J. Stat. Ann. § 2C:41-2 et seq. (West 1982). The defendants moved to dismiss the complaint under Rule 12(b)(6) of the Federal Rules of Civil Procedure on the ground that the action was barred by the act of state doctrine.

The District Court, having requested and received a letter expressing the views of the legal adviser to the United States Department of State as to the applicability of the act of state doctrine, treated the motion as one for summary judgment under Rule 56 of the Federal Rules of Civil Procedure and granted the motion.
The Court of Appeals for the Third Circuit reversed.
II
This Court’s description of the jurisprudential foundation for the act of state doctrine has undergone some evolution over the years. We once viewed the doctrine as an expression of international law, resting upon “the highest considerations of international comity and expediency,”
Oetjen
v.
Central Leather Co.,
The parties have argued at length about the applicability of these possible exceptions, and, more generally, about whether the purpose of the act of state doctrine would be furthered by its application in this case. We find it unnecessary, however, to pursue those inquiries, since the factual predicate for application of the act of state doctrine does not exist. Nothing in the present suit requires the Court to declare invalid, and thus ineffective as “a rule of decision for the courts of this country,”
Ricaud
v.
American Metal Co.,
In every case in which we have held the act of state doctrine applicable, the relief sought or the defense interposed would have required a court in the United States to declare invalid the official act of a foreign sovereign performed within its own territory. In
Underhill
v.
Hernandez,
Petitioners point out, however, that the facts necessary to establish respondent’s claim will also establish that the contract was unlawful. Specifically, they note that in order to prevail respondent must prove that petitioner Kirkpatrick made, and Nigerian officials received, payments that violate Nigerian law, which would, they assert, support a finding that the contract is invalid under Nigerian law. Assuming that to be true, it still does not suffice. The act of state doctrine is not some vague doctrine of abstention but a
“principle of decision
binding on federal and state courts alike.”
Sabbatino, supra,
at 427 (emphasis added). As we said in
Ricaud,
“the act within its own boundaries of one sovereign State . . . becomes ... a rule of decision for the courts of this country.”
In support of their position that the act of state doctrine bars any factual findings that may cast doubt upon the validity of foreign sovereign acts, petitioners cite Justice Holmes’ opinion for the Court in
American Banana Co.
v.
United
*407
Fruit Co.,
Whatever Justice Holmes may have had in mind, his statement lends inadequate support to petitioners’ position here, for two reasons. First, it was a brief aside, entirely unnecessary to the decision.

was squarely decided on the ground (later substantially overruled, see
Continental Ore Co.
v.
Union Carbide & Carbon Corp.,
Petitioners insist, however, that the policies underlying our act of state cases — international comity, respect for the sovereignty of foreign nations on their own territory, and the avoidance of embarrassment to the Executive Branch in its conduct of foreign relations — are implicated in the present case because, as the District Court found, a determination that Nigerian officials demanded and accepted a bribe “would impugn or question the nobility of a foreign nation’s motivations,” and would “result in embarrassment to the sovereign or constitute interference in the conduct of foreign policy of the United States.”
*409
These urgings are deceptively similar to what we said in
Sabbatino,
where we observed that sometimes, even though the validity of the act of a foreign sovereign within its own territory is called into question, the policies underlying the act of state doctrine may not justify its application. We suggested that a sort of balancing approach could be applied— the balance shifting against application of the doctrine, for example, if the government that committed the “challenged act of state” is no longer in existence.
The short of the matter is this: Courts in the United States have the power, and ordinarily the obligation, to decide cases and controversies properly presented to them. The act of state doctrine does not establish an exception for cases and controversies that may embarrass foreign governments, but merely requires that, in the process of deciding, the acts of foreign sovereigns taken within their own jurisdictions shall be deemed valid. That doctrine has no application to the *410 present case because the validity of no foreign sovereign act is at issue.
The judgment of the Court of Appeals for the Third Circuit is affirmed.
It is so ordered.
Notes
Even if we agreed with the Government’s fundamental approach, we would question its characterization of the legal adviser’s letter as reflecting the absence of any policy objection to the adjudication. The letter, which
