Practice Relating to Rule 107. Spies
Section B. Status of spies
Cameroon’s Disciplinary Regulations (1975) states:
Members of the Armed Forces in organized units, francs-tireurs detached from their regular units, commando detachments and isolated saboteurs, as well as voluntary militias, self-defence groups and organized resistance formations are lawful combatants on condition that those units, organizations or formations have a designated commander, that their members wear a distinctive sign, notably on their clothing, that they carry arms openly and that they respect the laws and customs of war. These combatants must be considered prisoners of war. Anyone who does not comply with these conditions may be considered a spy subject to the applicable criminal sanctions.

Cameroon’s Instructor’s Manual (1992) states that a combatant caught spying “loses his status as a prisoner of war”.

Cameroon’s Instructor’s Manual (2006), under the heading “Non-Combatants”, states that
[S]pies are … considered non-combatants and do not benefit from the status of prisoner of war in case of capture … [S]pies must be treated humanely … [and] one must avoid … infringements of their physical or psychological integrity. These persons must be tried in accordance with the law of the state.
