Although corporate groups (herein after, CGs) are expanding in the present Ethiopian businessrnenvironment, their legal status particularly in the commercial code remained unregulated. Theyrnare now the sources of many legal and practical concerns among the legal actors and legalrninstitutions of the country. Among such concerns, the legal and practical issues in relation tornanticompetitive practices under the competitive environment and competition regime of Ethiopiarnare the major one. Particularly with respect to abuse of market dominance and anticompetitivernagreements, these CGs sparked critical legal issues that can be substantiated by practicalrnscenarios. But, on the other hand, the present competition law of Ethiopia doesnâ€™t recognizernthese CGs and remained within the spirit of the traditional corporate law mentality.rnThus, this study is interested in the examination, discussion and evaluation of the interplay ofrnthese CGs and Ethiopian competition law from legal and practical stand point. Its majorrnobjective is to explore and unveil the competition dimension of these CGs with particularrnemphasis on the rules of abuse of market dominance and anticompetitive agreements.rnWhile this study focuses on major CGs of Ethiopia for its general discussion EFFORT andrnMIDROC CGs are used as examples of the practical situation on the ground. The study employsrnpurposive sampling and observation, interview and library research techniques to collect its datarnwhich it will critically discusses, review, evaluate, analyze and interpreted to produce the output.rnAccordingly, this study concludes that CGs, despite their negative effect on the marketrncompetition via their acts of abuse of dominance and anticompetitive agreement, they remainedrnunregulated under the competition law of Ethiopia. As a result this study calls for proper andrntimely legal and policy reform in the form of having special laws governing these CGs.
