Practice Relating to Rule 106. Conditions for Prisoner-of-War Status
Section B. Levée en masse
Switzerland’s Basic Military Manual (1987) states: “The civilian population does not have the right to take up arms except in the case of a levée en masse
to resist an invader.”
The manual further states:
The civilian population of a non-occupied territory which, en masse
, takes up arms spontaneously at the approach of the enemy is entitled to commit acts of war, even if this population did not have time to organize itself, provided arms are carried openly and the laws and customs of war are respected.
