In 2003, when CNDD-FDD was still a rebel movement, it negotiated with the government an agreement that provided both CNDD-FDD combatants and members of the state security forces with “temporary immunity” from prosecution, but gave no further explanation of the concept.[19] A subsequent law, which applied to political leaders returning from exile, clarified that temporary immunity (more often referred to in Burundi as “provisional immunity”) applied to “politically motivated crimes” committed between independence in 1962 and the signing of the ceasefire in November 2003. The law provided no further definition of “politically-motivated” crimes; however, it explicitly excluded the crime of genocide, war crimes, and crimes against humanity from provisional immunity.[20]
