This study explored on the constitutional provisions and practice in Ethiopia‟s federal system with a particular reference to Konso ethnic group‟s quest for self-rule. The Konso ethnic group, which previously secured separate self-rule at the highest level of local unit, Special Woreda Status, has recently relegated to ordinary Woreda status after the establishment of the new „Segen Area Peoples‟ Zone‟ in 2011. Given that the federal project in Ethiopia is a new model (synthesis) that has replaced the failed „Nation-Sate‟ building project since 1991, selfgovernment to the NNPs has become the ideological core of the incumbent party and pillar of the constitution. As per the gist of the FDRE Constitution, the NNPs are the actual constituent units and composers of the federation, and hence they are entitled to unconditional self-determination right (Art 39 (1)). The merger has changed the Special Woredas to ordinary Woredas, at the same time shifted the nationality self-rule to multi-ethnic self-rule, which is a paradigm shift from favorable to unfavorable scenario in view of the practice of self-rule. Methodologically, the researcher employed qualitative research approach which relied on primary and secondary sources of data. The tools used to collect data were interviews, field observation, FGD and document analysis. Pertaining to the findings, even though both the FDRE and SNNPRS constitutions promised “unconditional right to every national, nationality and people to have the right to self-determination up to secession”, the Konso quest of self-rule was rejected, their previous semi-autonomous status was dissolved and relegated to ordinary Woreda. Unlike Special Woredas, the role of ordinary Woreda is restricted to functionary roles and/or public service provisions. The Woredas are not endowed with key identity related self-government autonomy like the power to determine on the working language and the power to fire and hire officials if deems necessary. As the power and function of service delivery institutions are downgraded, it creates inconveniency to people for service accession. Reduction of capital budget, decline in the pace of development program, particularly infrastructure of urban development program is critical issue. Thus, the SNNP regional government has not been abided by its original ideological pledge nor respected the very frame of reference- that of the constitution, pertaining to self-rule.
