With the end of the war in 2009, the need to address the widespread death, destruction, and displacement was overwhelming. Allegations against all sides of potential war crimes and crimes against humanity demands an independent investigation and the prosecution within a credible court of law of those responsible for international crimes committed during the final stages of the war and during its aftermath. The Centre for Policy Alternatives (CPA) has consistently called for such independent investigations and other accountability measures to address truth, justice, reparations and non-recurrence of violence in Sri Lanka. This appeal continues six years after the end of the war. In this report, CPA sets out a range of processes and mechanisms available to the Sri Lankan government to ensure accountability for serious human rights violations and alleged crimes committed during the war. While many stakeholders are identified in the report, the ultimate responsibility for truth and justice in Sri Lanka lies with its citizens; accordingly they must play the central role in the design and implementation of future processes and mechanisms. CPA hopes that the options provided in this report enrich the discussions and debates about the design and implementation of a credible domestic process with the long term goal of achieving truth and justice in Sri Lanka.
