Practice Relating to Rule 36. Demilitarized Zones
Section B. Attacks on demilitarized zones
Canada’s LOAC Manual (1999) states: “It is prohibited for parties to a conflict to conduct military operations in or to attack an area that they have agreed to treat as a demilitarized zone.”
The manual further states that an area loses its status as a demilitarized zone if used “for purposes related to the conduct of military operations where it has agreed not to do so”.
The manual considers that “making … demilitarized zones the object of attack” constitutes a grave breach of the 1977 Additional Protocol I.
Canada’s LOAC Manual (2001) states in its chapter on targeting:
1. It is prohibited for parties to a conflict to conduct military operations in or to attack an area that they have agreed to treat as a demilitarized zone.
…
4. An area loses its status as a demilitarized zone where:
…
b. a party uses the demilitarized zone for purposes related to the conduct of military operations where it has agreed not to do so.
In its chapter on “War crimes, individual criminal liability and command responsibility”, the manual provides that “making … demilitarized zones the object of attack” constitutes a grave breach of the 1977 Additional Protocol I.
Canada’s Geneva Conventions Act (1985), as amended in 2007, provides: “Every person who, whether within or outside Canada, commits a grave breach [of the 1977 Additional Protocol I] … is guilty of an indictable offence.”
