 Facing one crisis after another, Prime Minister Piroćanac, lacking the support of Prince, later King, Milan, had no room left to prepare a new, more liberal constitution that would replace the old one of 1869.Piroćanac, as most other Progressives, was in favour of a two chamber system, advocating the upper chamber of Parliament as an obstacle against populism (“despotism of the masses”), ascribed mostly to the then-opposition National Radical Party of Nikola Pašić.The upper chamber, consisting of intellectuals appointed by the King would, as he proposed, control the irresponsible and uneducated peasant, mostly Radical, deputies.
