Sudhakaran was removed from the state committee after he formally made a request in this regard. After his exclusion from the state committee, the party had not given him any post.
The 89-member state committee includes three ministers from the Pinarayi cabinet - Saji Cheriyan, Muhammad Riyas and V N Vasavan - apart from the CM himself.
The party had asked Sudhakaran not to distance himself from the CPM over the disciplinary action.
Disciplinary action has been witnessed in all districts, even in Assembly constituencies where the party secured big victories.
The inquiry report stopped short of saying that Sudhakaran tried to ensure the defeat of party candidate H Salam in the Ambalapuzha.
He was demoted to the district committee from the state committee in 2002 over factionalism within the party's Alappuzha district unit.
The CPM state secretariat took the action on the former minister after an internal enquiry found that he had cold-shouldered the party's chances in the assembly constituency.
The CPM had initiated disciplinary action across the state for the lapses during the election campaign.
Sudhakaran, who is isolated in the party over his alleged lack of cooperation during LDF's campaigning for the Assembly Polls in Ambalapuzha, has written a poem titled 'Nettavum Kottavum'
State minister Saji Cherian and Alappuzha district secretary R Nasser have backed Ambalapuzha MLA H Salim's allegation that G Sudhakaran was inactive during the assembly poll campaign.
