The doctrine refers to the leader of the
General League of Roman Catholic Electoral Associations,
Willem Hubert Nolens. He articulated this principle in 1922 after the League's board sought to forbid cooperation. Nolens' aim was not to exclude collaboration with the social democrats but rather to leave the door slightly open. Towards the end of the
interwar period, the doctrine lost its significance as the rise of fascism and the economic crisis led the SDAP to adopt a more responsible stance, removing several ideological obstacles. This resulted in the formation of the
second De Geer cabinet in August 1939, which included both the SDAP and the League's successor, the
Roman Catholic State Party (RKSP). After
World War II, the phrase "utmost necessity" was often referenced when the successor of the RKSP, the
Catholic People's Party (KVP), did or did not form a coalition with the successor of the SDAP, the
Labour Party (PvdA). Political scientist
Hans Daudt formalized this into a theory in 1980 (also known as the
Daudt doctrine), but it is generally rejected within political science. == References ==
