Local and regional self-government should, in fact, be treated as an important form of
competences sharing among the various levels of territorial and political organization,
thus as a system of vertical "power sharing". It must be taken into consideration for the
purpose of establishing adequate institutional solutions of mutual checks and balance
among not only different organs but among different power levels. Therefore, it is
necessary to try to precisely state, expand and guarantee self-government under the
Republic and Federal Constitutions. It has been made narrower in practice or easily
limited not only under the law, but also by the arbitrary decisions of certain organs of the
executive power.
