The purpose of this piece of work is examining practice of self-government in the SNNPRSrnwith particular reference to the Segen Area peoples’ Zone. Given that the federal project inrnEthiopia is a new model (synthesis) that has replaced the failed ‘nation-sate’ building projectrnsince 1991, self-government to the NNPs has become the ideological core of the incumbentrnparty and pillar of the constitution. As per the gist of the FDRE Constitution, the NNPs arernthe actual constituent units and composers of the federation, and hence they are entitled tornunconditional self-determination right (Art 39 (1)). The SNNPRS, which is one of the 9 subnationalrnunits of the FDRE, is known for extraordinary diversity constituting some 75% ofrnthe total NNPs of the federation. The NNPs of this Regional State practice self-rule at thernlocal level with territorial autonomy. The Regional State Constitution permits the indigenousrnNNPs of the Region to establish local self-government by adopting Zone/Special Woredasrn(Art 45(2)). The previously self-governing NNPs in the region namely: Konso, Dirashe, Burjirnand Amaro, had been exercising such right for not less than fifteen years. However, currentlyrnthey have been merged and established shared Zonal Administration known as Segen ArearnPeoples’ Zone incorporating newly emerged Woreda called Alle. The merger has changedrnthe Special Woredas to Ordinary Woredas, at the same time shifted the nationality self-rulernto multi-ethnic self-rule, which is a paradigm shift from favorable to unfavorable scenario inrnview of practice for self-rule. For examination of this study the method and procedurernemployed was qualitative in design with multiple data collection tools namely: documentrnanalysis, field observation, FGD, and interview. Triangulation and ethical consideration wasrnmade to come up with reliable and valid findings, conclusions, and recommendations. Thernsample technique utilized was purposive sampling- a non-probabilistic method. To this effect,rnconvenience and judgmental sampling was administered. The data gathered with this methodrnwas systematically organized followed by analysis and interpretation. As per the findings, thernmerger has caused negative outcome on the practice of self-rule to the NNPs. The conclusionrndrawn is that the merger has negated the constitutional promise and ideological commitmentrnof the ruling party besides the pragmatic negative outcome. Finally, the study suggestedrnpossible mechanisms to address the challenges of self-rule practice followed by the merger.rnKey terms: federalism, self-determination, self-government, ethnicity, and local government
