Explain the mode of acquisition - occupation
The mode of acquisition is occupation. It is a means by which a State can acquire territory which belongs to no other entity. The occupation must be effective and must be intended as a claim of sovereignty over the area. Initially, people used to acquire land by use of force and spread their boundaries gradually. A new norm was formulated under the UN Charter 2(4) which prohibited the use of force in order to occupy a territory. For example, Israel occupied a territory in west bank of Gaza. It was however, not given legal acceptability.
