It is necessary to examine more deeply the function of the judicial control of the State Administrative Court in realizing good government. The main problem to be answered in this study is how the State Administrative Court functions in the context of realizing good government, what factors affect the function and what steps are taken by the State Administrative Court in carrying out its functions to create good government.
