Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
Sweden’s IHL Manual (1991) notes:
Additional Protocol I … states that the contracting parties shall to the greatest extent possible assist each other in connection with penal procedures instituted as a consequence of grave breaches of the Geneva Conventions or the Protocol. The States shall also cooperate in extradition cases …
In the extradition request the government can refer to the article in Additional Protocol I concerning mutual assistance in criminal proceedings ([the 1977 Additional Protocol I], Art. 88:2), according to which due consideration shall be given to a request for extradition from the state in whose territory the alleged offence has occurred.
