The complex content thereof outlines a range of disciplines with their characteristic subject maƩer and methods. Primarily, these are: Constitution Theory; Constitution Dogmatism; Constitution History; Constitution Philosophy; Constitution Sociology; Economic Theory of Constitution; Constitution Politics.

It is caused by the objec-tive reality that involves every segment of the constitution. Though, the goal is the same: maximization of effectiveness of the constitution.
