Can a monarchy have a tripartite division of authority?
Can a monarchy have a tripartite (legislative, executive, judicial) division of authority*? Viz., can a single person (the monarch) exercise all three of these authorities, or does he need to delegate those tasks to others? In the latter case, is there an ordering among the three branches—viz., does the monarch act as one supreme branch and the other two subjected to it?
*A. Ottaviani, Compendium Iuris Publici Ecclesiastici (1954) defines each of these powers:
1. Legislative: "right of determining in an obligatory manner the things which are necessary and useful for attaining the end of the society" (p. 43)
2. Judicial: "the right of declaring and proposing in an obligatory manner which concrete acts of subjects are conformed or contrary to right, and the legitimate effects of this conformity or contrariety" (p. 49)
3. Executive: "right of enforcing the application of laws and sentences, of directing persons or of disposing of things, and of removing all obstacles which impede the full possession of the social end" (p. 61)
