Fearing deportations at the  deposition, He invoked the Fifth Amendment right against self incrimination. Court rulings
The District court agreed that Balsys testimony could put him in danger with foreign countries but claimed that "The reasonableness of his fear is not challenged by the Government, and we thus squarely face the question whether a criminal prosecution by a foreign government not subject to our constitutional guarantees presents a “criminal case” for purposes of the privilege against self-incrimination." Balsys appealed this decision to the Second Circuit but in a 7-to-2 decision the court held. With Justice Souter delivering the Courts Opinion stating fear of self incrimination and a following prosecution by a foreign country does not fall under the Fifth Amendment right against self incrimination.
