Theory of parliamentary regimes presumes that parliament can express vote of no confidence in government. On the other hand executive power (government or head of state) is endowed with right to dissolve the parliament. However, these “doomsday devices” are not in balance in many parliamentary regimes, including the Czech Republic. On the basis of a comparative analysis of dissolution provisions in the constitutions of European states the article argues that the government in the Czech Republic should be given the right to dissolve the lower chamber at least in case that the latter expresses vote of no confidence in the former.
