One of the hallmarks of the Foreign Corrupt Practices Act has been that it cannot be used against a foreign official who demands or takes a bribe for helping a company win a contract or retain business.

A bill introduced in Congress this month seeks to change that. Called the Foreign Extortion Prevention Act, the legislation would expand the prohibition on bribery to foreign officials who demanded or solicited bribes.

The Foreign Corrupt Practices Act’s prohibition on paying bribes abroad is limited to companies in the United States and those acting in this country. It has always excluded the foreign official who takes the bribe, and courts over the years have reaffirmed that.

In United States v. Castle, a 1991 decision, the United States Court of Appeals for the Fifth Circuit found that two Canadian officials could not be prosecuted for a conspiracy to violate the F.C.P.A. because Congress exempted foreign officials. In United States v. Hoskins, a 2018 ruling, the federal appeals court in Manhattan held that a foreign national who was never in the United States could not be prosecuted under the foreign bribery law because “Congress did not intend for persons outside of the statute’s carefully delimited categories to be subject to conspiracy or complicity liability.”

The bill, which has both Democrats and Republicans as sponsors, would put the prohibition on a foreign official’s accepting a bribe under the federal anti-bribery statute, 18 U.S.C. § 201, rather than the Foreign Corrupt Practices Act. The proposal would also make it a crime for a foreign official “otherwise than as provided by law for the proper discharge of official duty” to demand or accept anything of value for being influenced in the performance of official responsibilities.

But putting the prohibition under the federal anti-bribery statute would subject it to the limitations the Supreme Court placed on the law in its 2016 ruling in McDonnell v. United States. That case overturned the conviction of a former governor of Virginia by rejecting a broad reading of what is an “official act.” The justices explained that it must involve “a formal exercise of governmental power that is similar in nature to a lawsuit, administrative determination or hearing.” They found that “merely setting up a meeting, hosting an event or contacting an official — without more — does not count as an ‘official act.’”

Favoring a business by arranging meetings or contacting other foreign officials to help it win a contract may not rise to the level of an “official act,” especially if the foreign official who received the bribe did not have the direct authority to decide who should be awarded a contract. So the potential limitations on the federal bribery statute could be read into prosecutions of foreign officials for accepting bribes that violated the F.C.P.A.

The F.C.P.A. also contains two defenses that were added in 1988. One is the “local law” defense, which allows a defendant to show that under the written laws and regulations of the place where the bribe occurred that it was not illegal. Another defense permits small “facilitation payments” to obtain routine government action in the country. In both situations, a foreign official could argue that these defenses should preclude liability for accepting a payment.

A greater potential issue for the Justice Department if the legislation becomes law is whether a foreign official will be brought to the United States to face a criminal charge. If the person is still in office, a foreign government may be reluctant to send the person to America. But a criminal indictment would most likely limit where the foreign official could travel. The person would need to avoid countries that have an extradition treaty with the United States.

The Department of Justice has not been without tools to punish foreign officials who engage in bribery. The money-laundering statute allows a foreign official receiving money through bribery, misappropriation or theft of public funds to be charged with a crime. Federal prosecutors could also use the Travel Act, which prohibits traveling into the United States to engage in bribery.

Both statutes, though, require either travel to the United States or a financial transaction using the United States financial system.

The new legislation would make it much easier to pursue a foreign official. The Justice Department would not have to show a connection to the United States beyond a payment by an American company.

Whether it would result in an increase in prosecutions is a different question. Still, simply charging the official could have the effect of identifying who was responsible in a country for accepting illegal bribes. That should make it easier for American companies and their employees to demand fairness from foreign officials rather than being extorted for payments.
