Administrative act appeal within the administrative procedure: comparative legal analysis by O. O. Markova

“…We consider it expedient to move away from the concept of consideration of a complaint by a higher body, since administrative officials often violate the principle of impartiality and fairness when considering a complaint, and to establish that the subject of consideration of a complaint is a collective body – a commission formed by a higher-level administrative body, to provide for pre-trial resolution of a conflict (dispute), which involves individuals filing a complaint within the framework of an administrative appeal, as a mandatory condition, which will solve the problem of parallel judicial review. …”
