Practice Relating to Rule 129. The Act of Displacement
Section A. Forced displacement
Mexico’s Army and Air Force Manual (2009) states: “The States party to the  Geneva Conventions undertake to: … prohibit … deportation.”
In a section on the 1949 Geneva Convention IV, the manual also states:
234. Protection of persons
A. One of the most important provisions is the one prohibiting deportations. Individual and mass forcible transfers and deportations of protected persons from occupied territory to the territory of the occupying power or to that of any other country, occupied or not, are prohibited, regardless of the reason.
Mexico’s Penal Code (1931), as amended in 2000, punishes the forcible transfer of children under the age of 16 years to another group, when committed as a part of a genocide campaign.
