14. Illegal expeditions.

If any person within Her Majesty's dominions and without Her Majesty's licence1 prepares or fits out any naval or military expedition to proceed against the dominions of any friendly state2, any person engaged in the preparation or fitting out or assisting in it, or employed in any capacity in that expedition, is guilty of an offence3. If the illegal expedition is to any extent prepared within Her Majesty's dominions, the participation in it outside those dominions by a person having British nationality is also an offence
