The Jul 22 CC's resolution said Achuthanandan's stand that his differences with the state leadership pertained to "political and ideological issues had no basis whatsoever."
On the contrary, his recent statements smacked of factional tendency, the resolution published today by the party's official organ "Deshabhimani" said.
Citing some highly critical statements made by the senior leader against the state set-up controlled by his arch foe Pinarayi Vijayan, the resolution said these amounted to hurling accusations at the leadership in public and weakening CPI(M).
It noted that Achuthanandan himself had "self-critically" admitted that he committed a mistake by comparing Vijayan with the late SA Dange, who presided over the split in the undivided Communist Party of India in 1964.
Similarly, he also agreed that he should not have visited the home of the murdered Marxist rebel and RMP leader TP Chandrasekharan on the day of the assembly by-election from Neyyattinkara (which the CPI-M lost to Congress).
The CC resolution also said the controversial speech by former Idukki district secretary MM Mani that the party had eliminated its foes in the past also did grievous damage to the party's image.
The special CC session was held on Jul 21 and 22 exclusively to discuss the deep divisions in the Kerala unit. The long-running tussle between Achuthanandan and Vijayan intensified in the wake of the Chandrasekharan murder.
The senior leader had then made an unsparing attack on Vijayan, holding that the state leadership should have tried to bring back rebels like Chandrasekharan, instead of castigating them as "renegades".
