There is a principle of American law, upheld by the Supreme Court, that a Federal law is only supposed to be considered of "extraterritorial" application (applies outside the boundaries of United States territory) if the Congress specifically intended that application, and was signified by including such language within the law itself.https://en.wikipedia.org/wiki/Extraterritorial_jurisdiction
"In Morrison v. National Australia Bank, 2010, the Supreme Court held that in interpreting a statute, the "presumption against extraterritoriality" is absolute unless the text of the statute explicitly says otherwise."
"The Supreme Court threw out the lawsuit after invoking the presumption against extraterritoriality. That canon of statutory interpretation instructs judges to assume “that legislation of Congress, unless a contrary intent appears, is meant to apply only within the territorial jurisdiction of the United States.”[8] In applying the presumption in RJR Nabisco, however, a majority of four Justices[9] rejected multiple indications that Congress intended RICO’s private right of action to extend abroad[10] while raising the bar on what Congress must do to make its extraterritorial expectations clear.[11]" [end of quote]
"THE RULE OF DUAL CRIMINALITY: Even if extradition is sought only under the computer intrusion indictment, it will still need to meet the test of dual criminality, found in Article 2, which provides that "An offense shall be an extraditable offense if the conduct on which the offense is based is punishable under the laws in both States." Although computer hacking is no doubt also a crime in the U.K., there is a further wrinkle of territoriality, because Assange's alleged offense was committed outside the United States. Another section of Article 2 provides:
If the offense has been committed outside the territory of the Requesting State, extradition shall be granted in accordance with the provisions of the Treaty if the laws in the Requested State provide for the punishment of such conduct committed outside its territory in similar circumstances. If the laws in the Requested State do not provide for the punishment of such conduct committed outside of its territory in similar circumstances, the executive authority of the Requested State, in its discretion, may grant extradition provided that all other requirements of this Treaty are met."
Unlike the U.S., however, Britain apparently takes a strict view of territorial jurisdiction. According to The New York Times, Britain has already denied a U.S. extradition request for computer intrusion, on the grounds that the offense was committed on British soil and would therefore have to be tried in the U.K.
