It is important that Security Council member States and regional organizations ensure that mediators in the peace and preventive diplomacy process can contribute to ensuring accountability, including by encouraging the parties concerned to envisage transitional justice clauses in peace agreements. Those responsible for serious crimes committed during conflicts, including gender-based violence, must be excluded from all branches of Government, and the principle of no amnesty or any other form of indulgence for the perpetrators of such offenses must be applied. Such measures should be implemented comprehensively and should also envisage the full rights of victims to redress.
