Practice Relating to Rule 129. The Act of Displacement
Ireland’s Basic LOAC Guide (2005) states:
One of the most important clauses dealing with the protection of persons in the territory of any Occupying Power is that prohibiting deportation. Individual or mass forcible transfers (i.e. the ethnic cleansing conducted by all three belligerent factions in Bosnia) are prohibited regardless of their motive.
