The in 1945 established Christian Social Party (The Flemish CVP and the French speaking PSC) showed some important differences in comparison with the prewar Catholic Party. The structure of the CVP-PSC was unitary, based upon individual membership instead of the prewar federation of « estates » (standen). With this unitary structure, the founding fathers of the CVP-PSC tried to avoid the conflicts between the estates, a permanent cause of criticism and disurtity in the Catholic Partyduring the interwar period. In spite of the new organizational structure of the CVP-PSC, new methods of informal recognition of the estates were introduced for the aggregation of their claims and their representation within the party. The way this informal recognition of the estates in the CVP-PSC was solved, is briefly described in the first part of this article. Subsequent to the survey of the evolution of the political position of the estates and their relation to the CVP-PSC, the composition of the lists of candidates in the CVP-PSC for the general elections of 8 november 1981 is discussed. Special attention is paid to the balancing in number and the ranking ofcandidates from the estates. Finally, the representation of the estates in the parliamentary group of the CVP-PSC is calculated for the general elections of 1974, 1977, 1978 and 1981.
