ABSTRACT The concern of this study was to examine the legal parameters and limitation on one‟s right of contesting for leadership in Tanzania. The main problem which furnishes for this study to be conducted was the lack of well and or clear articulation of the legal parameters and limitations with regards to the right of participating in public affairs as leaders, the right which is attainable when one is legally accorded and freely contests in elections. Thus, the right to contest for leadership in Tanzania however being provided by the Constitution of the United Republic, the same right is being restricted to be accessible only to those who are members and candidates nominated and or sponsored by political parties. Since that, joining with a political party is a conditional precedent before one opts to directly participate by contesting for parliamentary, presidential and or local government posts. It is from the findings of this study that the legal regime in Tanzania on this area does not neither match with international nor regional adopted standards in allowing its citizen to participate in governing their affairs direct as leaders, and that the current legal regime does not take Tanzania to an ideal level. For want of an ideal system recommendations has been made from this study effecting for the amendments of certain provisions of the Constitution and some other enabling electoral laws, and further the study recommends for executive branch to pull by taking all the necessary steps to the accomplishments of the ongoing constitutional review process and incorporate therein ideal provisions allowing citizens to freely contest for leaderships.
