Practice Relating to Rule 37. Open Towns and Non-Defended Localities
Bosnia and Herzegovina’s Military Instructions (1992) provides:
In order to ensure full protection of such place [an open town], it is necessary that the other side to the conflict also recognizes the status of the city and to reach an agreement on the necessary preconditions in that regard. These preconditions are usually related to the following: the places should not be defended and no armed forces should be deployed in it; no military units should cross its territory for the purpose of transporting military material; no activities of military importance should be undertaken in industrial plants; and there should be no liaison with local armed forces and allied armed forces.
