Constitutionalism and legal order in Tanzania have been subject to significant transitions since independence, influenced by both domestic political dynamics and external factors such as international law and economic integration. A comparative analysis approach is employed, drawing from case studies of past and current constitutional revisions, as well as empirical data from Tanzanian courts and legislative records. The study integrates qualitative and quantitative methods to provide a comprehensive understanding of the legal landscape in Tanzania. The findings indicate that while there has been progress in judicial independence and legal reforms, challenges persist in ensuring consistent application of laws across different sectors and regions in Tanzania. Despite the strides made towards constitutionalism and the rule of law, persistent issues related to judicial independence and regional disparities require further attention and policy interventions. The recommendations include strengthening institutional mechanisms for legal compliance, enhancing judicial training programmes, and promoting cross-regional collaboration in legal implementation.
