The mechanism of checks and balances in the system of state power in Ukraine through the prism of modern constitutionalism: deficiencies and prognostic modernization

ISSN online: 2617-9776 print: 0869-2491

The article provides a scientific analysis of the mechanism of checks and balances in the system of state power in Ukraine through the prism of modern Ukrainian constitutionalism. Based on a systematic scientific and practical analysis of the shortcomings and conceptualization of the problems of the functioning of this mechanism, proposals are formulated for its predictive modernization. 

Thus, it has been proven that the main elements of the mechanism of checks and balances in the context of modern Ukrainian constitutionalism should be the following: compliance by state authorities with the principle of acting exclusively within the limits of their powers established by the Constitution of Ukraine and in accordance with the law; the presence of competent interrelations between all state authorities, which is determined by their competent capabilities to exercise mutual control, adhering to the idea that the independence of the branches of power does not mean their limitlessness (in terms of functions, powers, competence); on the contrary, each of the authorities, protecting itself from possible interference, must control and restrain the other authority; interdependence of state authorities in their formation and when appointing officials; the presence of constitutionally defined opportunities for mutual holding to constitutional responsibility (the right to dissolve parliament, a vote of no confidence in the government by parliament, impeachment of the head of state, etc.); the presence of organizational and legal forms and procedural means (mechanisms) defined in the Constitution and legislation of Ukraine, which would be aimed at regulating and overcoming possible conflicts between state authorities; the constitutionally enshrined principle of interaction between legislative, executive and judicial authorities; effective parliamentary and judicial control over the executive branch in conditions of martial law and other existential challenges. 

Keywords: constitutionalism; state power; separation of powers; legislative power; executive power; judicial power; checks and balances; interaction of branches of government; rule of law; parliamentary control; Constitution of Ukraine.
