The [ICTR] Chamber notes that the Tutsi population does not have its own language or a distinct culture from the rest of the Rwandan population. However, the Chamber notes that there are a number of objective indicators of the group as a group with a distinct identity. Every Rwandan citizen was required before 1994 to carry an identity card which included an entry for ethnic group…. The Rwandan Constitutions and laws in force in 1994 also identified Rwandans by reference to their ethnic group…. Moreover, customary rules existed in Rwanda governing the determination of ethnic group, which followed patrilineal lines of heredity…. The Rwandan witnesses who testified before the Chamber identified themselves by ethnic group…. Moreover, the Tutsis were conceived of as an ethnic group by those who targeted them for killing.
