In the petition, he questioned the action of Mani being sworn in as Minister for Finance, Law and Housing in the Cabinet "by violating Clause XXII of the Constitution" of KC(M), which was accepted and approved by the Election Commission for the purpose of continuation its registration.
George cited Clause XXII of the party's constitution which reads "if the party chairman, vice chairman, treasurer or secretaries became a minister, Speaker or Deputy Speaker, they shall resign their previous post before assuming charge as Minister, Speaker or Deputy Speaker."
He said it is also a ground to deregister Kerala Congress(M) as a political party.
Last week, Kerala Congress(M) high-power committee, chaired by Mani, had suspended George as vice-chairman and member of all party committees, reducing him to the status of only a member.
The party had accused George of persistently ridiculing it and the UDF leadership.
