Aurelia Colombi Ciacchi. Ronald Holzhacker University of Groningen. Netherlands Abstract Civil Society Organizations (CSO. have played an increasingly vocal role in their struggle to advance both human rights protection and promotion in Southeast Asian countries. Most notably. CSOs have become a more important actor in dealing with human rights issues in particular by virtue of their role in drawing attention to human rights violations. In the case of massive human rights violations happening in Southeast Asia. CSOs pursue various strategies to address and try to end such abuses. Spreading information of human rights violations occurring in each member state to regional peers, and then finding new allies such as international organizations to put pressure back to human rights-violating states, in what is characterized as a dynamic of the boomerang model, one of the prominent strategies CSOs use to relieve human rights violations. Another strategy recently observed involves CSOs reaching out to powerful judicial institutions whose decisions can be legally binding on a violating state. This paper applies the boomerang model theory to the efforts of CSOs, specifically with respect to their work in helping to end the extrajudicial killing of drug dealers in the Philippines during President DuterteAos tenure, to display how the dynamics of the boomerang model works and what this strategy has achieved in terms of ending the extrajudicial killings. Beyond the boomerang model, this paper further demonstrates the strategy of CSOs in reaching out directly to powerful judicial institutions, in this case the International Criminal Court (ICC). The paper discusses why CSOs pursued this strategy of reaching out to the ICC, bypassing the regionAos human rights institutionAithe ASEAN Intergovernmental Commission on Human Rights (AICHR). Keywords: Civil Society Organizations (CSO. Extrajudicial Killing in the Philippines. The International Criminal Court (ICC) INTRODUCTION In Southeast Asia, civil society organizations (CSO. across the region have for over a decade, been challenging the regional organization, the Association of Southeast Asian Nations (ASEAN), to address issues and concerns impacting citizens. 1 In December 1997.

Eduardo Stanati Netipatalachoochote. Aurelia Colombi Ciacchi. Ronald Holzhacker ASEAN officially widened its policy-making to include CSOs. 2 Additionally, the Bali Concord II 2003 and the Vientiane Action Program 2004 restated commitments regarding civil society engagement with ASEAN. 3 The idea of collaborating with CSOs became a consistent part of the ASEAN rhetoric and was reaffirmed in article 1. of the ASEAN Charter 2007. 4 At present, there are many CSOs working on different interests and issues in this region. The exact number of CSOs seems difficult to pinpoint as some of them exist only in name while in reality they may not be reachable, and some have merged with other CSOs. According to the 2016 USAID CSO Sustainability Index for Asia, the Philippines has 279,499 registered CSOsAithe highest number in the region. Indonesia. Thailand, and Cambodia have about 250,000. 14,000. and 5,000 respectively. 6 Despite this high number, it is surprising that only 52 CSOs have been accredited by ASEAN. The accreditation is officially regulated by the Guidelines on Accreditation of Civil Society Organizations. The first Guidelines were adopted at the 5th Meeting of the 19th ASEAN Standing Committee (ASC). Manila, 16-18 June 1986, and the current version was adopted by the 19/2012 the Committee of Permanent Representatives (CPR) Meeting on 5 th November 2012 and noted by the 11th the ASEAN Coordinating Council (ACC) Meeting on 17th November 2012. With respect to CSOs in the human rights field, a number of CSOs have emerged to be a facilitator on matters of human rights when the Working Group for an ASEAN Human Rights Mechanism (Working Grou. was created in 1995, because the Working Group consisted of parliamentary human rights committees, the academic community, and CSOs. 8 Official statements of the Working Group show that several CSOs such as MARUAH Singapore, the Philippine Alliance of Human Rights Advocates (PAHRA), the Asia Foundation, and Friedrich Naumann Stiftung have often participated in C Tadem.
