Masyumi Party
Besides being criticised by other parties, Natsir Cabinet also got criticised by its own core party, Masyumi. The criticism was aimed at December 1949 congressional decision that banned a party's general chairman from becoming a minister. The purpose of this congress was party consolidation but it was changed by the Party Council in Bogor at 3-6 June 1950 that profess the federal system could no longer be maintained. In order to not violated the congress decision too much, Natsir was deactivated from his position as the general chairman of Masyumi Party and was replaced by Jusuf Wibisono.
