Practice Relating to Rule 157. Jurisdiction over War Crimes
Uganda’s Geneva Conventions Act (1964) provides:
Any person, whatever his nationality, who, whether within or without Uganda commits or aids, abets or procures the commission by any other person of any grave breach of any of the [1949 Geneva] Conventions … commits an offence and on conviction thereof [shall be punished].
Where an offence under this section is committed without Uganda a person may be proceeded against, indicted, tried and punished therefor in any place in Uganda as if the offence had been committed in that place, and the offence shall, for all purposes incidental or consequential on the trial or punishment thereof, be deemed to have been committed in that place.
