The Review has decided to contribute to the discussion on whether the rules of occupation should be strengthened, clarified, or developed, by devoting the present edition to the subject of the grey areas and contentious issues arising from occupation law. The Review asked experts on matters related to occupation to offer their perspective, whether historical, military, or legal, in order to explore six key questions. How and along what lines has occupation law developed? When does the invasion phase end and the duties of occupiers and the rights of people living under occupation begin? Is the law always suited to prolonged occupation? Is there any justification for changing the institutions and/or the laws of an occupied territory? What is the role of the military in the occupation of a territory? What is the role of human rights?
