This thesis attempts to explain the role of indigenous institutions in dispute settlement among thernTulama Oromo of the Sulultadistrict the case of Qaalluu Oofaa Abbuukko. There are variousrnlocal dispute settlement institutions in sululta district such as jarsumma, peace settlement atrnlinage; tokko shanne, Qaalluu institution and dispute settlement among different religiousrninstitutions. However, due to limitation of time and resource this study mainly focused on thernrole of Qaalluu institution to settle the dispute. The main focuse of the thesis is to explore therncauses of disputes and indigenous dispute settlement mechanisms with particular area on thernrole of Qaalluu Oofaa Abbuukko institution in the study area. For this study I employed bothrnprimary data and secondary resources. The relevant primary data were colected throughrnqualitative tools such as in-depth interviews, observations, focus group discussion and selectedrncase studies. The secondary data were published and unpublished articles, journals, newsrnpapers, books, MA thesis and PHD researches. In this study I tried to set out different types ofrndisputes taking place in the area such as, money borrowing or lending, property like land,rnlivestock and cereals, in appropriate sexual relations, marital dispute, and inheritence and theftrncases. The study also explores different mechanisms of dispute settlement, which are generalyrndivided into formal (state-based) and indigenous (informal) dispute settlement mechanisms. InrnQaalluu institution, the disputants do not call wases (guarantors). However, insecularrninstitution, and formal court the disputants call upon their wases (guarantors), the process takesrnshort period compared to the formal state structures. Active decision-making and quickerrndecision are given to the disputants. Arbitration in the context of Qaalluu court is quicker.rnThe procedures are generally easy and more economical, those disputants who cannot affordrnthe above in the formal structure mostly bring their cases before this customary institution; courtrnstructure is takes place at district level. Discussing settlement the dispute and reconcilationrn(araarsuu) are not complex like formal courts. The last process, reconciliation, is not availablernin the formal dispute settlement setting. All disputants are equal before this customaryrninstitution and it is free from corruption. There are many advantages of indigenous institutions with regard to equality before customaryrnlaws. In Qaalluu Ofaa Abbuukko institution post-recouncilation the disputants and elders arernenjoy together in the same room by taking traditional or local drinking this show that to confirmrnthe reconciliation. However, in the formal court, the judge and disputants are very far apart, nornfreely contact and discuss with them, in addition, no false witnesses in Qaalluu. In therngovernment system, it is usually difficult for the plaintiff to win the case because of the falsernevidences arranged by the accused. In the absence of evidence, the Qaalluu look at the casernwhereas in the absence of evidence the government court dismisses the case. Therefore, thernQaalluu court is the best choice particularly if there is no evidence for some plaintiff. Casesrnwithout evidences have no values before the formal dispute settlement mechanism. Due to this,rnthe local people preferre to employ this strategy as the principal approach to manage disputernthat they come across in their every encounters.rnIn this thesie, we accuired the knowledge how Sululta Oromo practices customary and spiritualrnlaws, rules and regulation in the indigenous judicial system to confirm peace and recouncilationrnamong the disputants by using Qaalluu Oofaa Abbkko institutions. The institutions deal withrnsome disagreements which araised from the communities. They serve equally, without payment,rnat village or local, safe time, solve unwitnessed issue, using native language and make oth, curse and blessing to confirm peace. The studies thus give description on how the Oromo in general and Sululta Oromo traditional institutions interact to settle the dispute, focus on harmony and knowledge of recouncilation inorder to resolve dispute
