The majority of conflicts across the global today ar non-international in nature. This has led to the challenge of making relevant, a body of principles that were developed in the context of international conflict, to non-international armed conflicts. The objective of this paper is to demonstrate the extent of this challenge from a Sri Lankan perspective. The article analyses selected attempts made in Sri Lanka to implement IHL and to enact enabling legislation for the fulfilment of her international obligations under IHL. It identifies some challenges that the Sri Lanka situation poses to the applicability of the law on non-international armed conflict and makes suggestions as to measures that could be adopted in Sri Lanka to minimise suffering caused by the armed conflict and suggests direction for the future development of the law relating to non-international armed conflict.
