This book analyses the institution of Minister of Justice in the constitutional systems of several European countries: the United Kingdom, Ireland, Germany, Austria, France, Italy, and Poland. The research was based on the hypothesis that the Minister of Justice is, in fact, inessential, because the institution is to a large extent incompatible with the principles of the separation of powers and the independence of the judiciary. Certain competences currently assigned to this institution might be allocated to other bodies and departments, including those that function as part of the government (the Cabinet), without any prejudicial effect on the functioning of the state.The book is aimed at academics in the field of comparative constitutional law.Piotr Mikuli, Ph.D. (habil.), is a professor at the Jagiellonian University in Kraków and head of the Chair in Comparative Constitutional Law.
