La “royal prerogative” e la forma di governo del Regno Unito

The author examines the evolution of the constitutional order of the United Kingdom by examining the evolution of royal prerogative powers starting from the study of the most relevant constitutional conventions that regulate the relations between the Monarch, the Government and the Parliament. The essay focuses on the origin of the prerogative powers and on the link between Sovereign and Prime Minister in their exercise. He highlights how, more recently, furthermore, the transformations of the English Constitution have been realized through legislative reforms of the Parliament that have regulated some aspects of the Constitution first regulated by the conventions. In particular, more recently, the power of dissolution of the House of Commons. At the same time there has been a strong limitation of the powers of prerogative by case law, as happened in the Miller case and Miller 2/Charry case. The reform of the power of dissolution of the House of Commons, no longer exercisable by the Monarch on the discretionary advice of the Prime Minister, the greater recourse to coalition governments and the role of the Courts. It also seems to be inferred from the recent institutional events concerning Brexit. In any case, it will be necessary to look at the practical application that will receive the Fixed-Term Parliament Act of 2011 and it is not certain that these reforms are destined to last seem to limit the Prime Minister's role in the Parliament.
