The article deals with the issue of incompatibility of public functions in the Czech legal environment and the relation of the accumulation of functions to the principle of division of power and the ability to promote the interest of society as a whole. After a general introduction explaining the basic concepts of incompatibility, the article examines the question of whether the cumulation of public functions by Members of Parliament can bring with it some rather neglected negative manifestations today, justifying considerations of enshrining their incompatibility, and whether the assessment of this issue differs in any way depending on whether we are talking about Chamber of Deputies, or Senate.
The author concludes that excessive cumulation of functions of a member of the Parliament of the Czech Republic and a member of a municipal or regional council may in some cases be detrimental to the promotion of societal interests, especially in the Senate, and encourages the Czech legislator to thoroughly consider tackling these cases of cumulation by seting respective functions incompatible.
