United States v. Ning WenUnited States v. Ning Wen
A jury found Ning Wen guilty of violating the export-control laws by providing militarily useful technology to the People’s Republic of China without the required license. See
As enacted in 1978, FISA applied to interceptions the “primary purpose” of which was foreign intelligence; as amended in 2001 by the USA PATRIOT Act, the statute applies to interceptions that have international intelligence as a “significant purpose”.
The statutory question under the current version of the Act is whether acquiring international intelligence is a “significant purpose” of the intercept. The intercept’s “primary” purpose may or may not be pertinent to the fourth amendment (we discuss that subject below) but is not pertinent to the validity of the intercept under the statute. Like the district court, we have reviewed the affidavits
in camera
and conclude that the statutory standards for an intercept order have been satisfied. There is no basis for suppression under FISA itself.
The fourth amendment does not supply a better footing for exclusion. FISA requires each intercept to be authorized by a warrant from a federal district judge. See
At one time it was seriously questioned whether an intercept order is a “warrant” for constitutional purposes, see Telford Taylor,
Two Studies in Constitutional Interpretation
79-88 (1969), but characterization was settled in favor of “warrant” status by
Dalia v. United States,
The only plausible constitutional objection to the warrant actually issued would be that FISA uses a definition of “probable cause” that does not depend on whether a domestic crime has been committed. Under
Yet we know from the administrative-search cases that the “probable cause” of which the fourth amendment speaks is not necessarily probable cause to believe that any law is being violated. The Court held in
Camara v. Municipal Court,
These principles carry over to FISA. Probable cause to believe that a foreign agent is communicating with his controllers outside our borders makes an interception reasonable. If, while conducting this surveillance, agents discover evidence of a domestic crime, they may use it to prosecute for that offense. That the agents may have known that they were likely to hear evidence of domestic crime does not make the interception less reasonable than if they were ignorant of this possibility. Justice Stewart’s position that the plain-view doctrine is limited to “inadvertent” discoveries, see
Coolidge v. New Hampshire,
Affirmed.
