This dissertation analyses the domestic implementation of the repression of violations of International Humanitarian Law. Through this analysis it seeks to clarify the obligations placed on States under International Humanitarian Law to ensure an effective and workable system for the repression of violations. In assessing these obligations, this dissertation attempts to highlight the importance of an effective system that is properly implemented in a timely manner. It is shown that the obligations placed on States are not burdensome and are outweighed by the advantages of proper implementation. This dissertation demonstrates these advantages through a case study of Uganda where the consequences of the failure to implement an effective system of repressions of violations of International Humanitarian Law are documented. Practical solutions that may assist in remedying the defective system to repress violations in Uganda are provided. It is argued not only for the need to properly implement an effective system of repression of violations, as required under International Humanitarian Law, but for the need to implement a system that goes beyond that which States are legally obliged to do.
