Those facing action are Achuthanandan's Press Secretary K Balakrishnan, Personal Assistant A Suresh and Additional Private Secretary V K Sasidharan.
According to party sources, the action is based on an inquiry against them conducted by a party panel headed by LDF convenor Vaikom Viswan.
The charge against them was that they had leaked to media contents of a review document prepared by the party state committee for internal circulation during the CPI(M) congress in Kozhikode last year.
However, the decision would be implemented only after getting the concurrence of the central leadership, the sources said.
The state secretariat of the party had on Thursday recommended action against the three party members, who have been serving as Achuthanandan's personal staff.
