This book contains a comparative constitutional analysis of the constitutional/judicial review systems in 208 countries. Itgives a broader overview and deeper knowledge of such systems around the world. The study was created by the students research group of the European Law School to the New University in Slovenia, conducted by professor Arne Marjan Mavčič.

The institutional and functional comparative method is making readers familiar with constitutional systems of different countries, drawing on features for individual world regions and considering specific types of constitutional and judicial review. Using a special systemic presentation model, the researchers treat different systems and institutions that hold their exclusive decision-making power on constitutional matters. Their review quite often covers legislative acts that are the highest legal instruments of a specific legal and political system. This gives each constitutional/judicial review institution a special status with power to provide constitutional and/or review under the system of the separation of powers, especially in relation to the legislative power in that it may even annul statutes adopted by the legislative body.

Each systemic presentation model is completed depending on the currently available data (sources).
