Principle of ubiquity

In German criminal code, principle of ubiquity, (Ubiquitätsprinzip, Section 9 §1 Alt. 3 and 4 of the Strafgesetzbuch) states that the crime is considered to have occurred in the place of the action of the perpetrator or in the place where the harm occurred.^[1]

Its parallel in the United States law is the combination of the objective territoriality principle (the effects doctrine) and subjective territoriality principle.^[1]

For example, if a person sends a poison cookie from Germany to a United States resident and the latter one suffers, then both Germany and the United States have a jurisdiction over the case.^[1]
