And, for greater certainty, the Fourth Geneva Convention...

Art. 45. Protected persons shall not be transferred to a Power which is not a party to the Convention.

This provision shall in no way constitute an obstacle to the repatriation of protected persons, or to their return to their country of residence after the cessation of hostilities.

Protected persons may be transferred by the Detaining Power only to a Power which is a party to the present Convention and after the Detaining Power has satisfied itself of the willingness and ability of such transferee Power to apply the present Convention. If protected persons are transferred under such circumstances, responsibility for the application of the present Convention rests on the Power accepting them, while they are in its custody. Nevertheless, if that Power fails to carry out the provisions of the present Convention in any important respect, the Power by which the protected persons were transferred shall, upon being so notified by the Protecting Power, take effective measures to correct the situation or shall request the return of the protected persons. Such request must be complied with.

In no circumstances shall a protected person be transferred to a country where he or she may have reason to fear persecution for his or her political opinions or religious beliefs.

The provisions of this Article do not constitute an obstacle to the extradition, in pursuance of extradition treaties concluded before the outbreak of hostilities, of protected persons accused of offences against ordinary criminal law.
