The Milan Pandey faction filed a case at the Supreme Court against Bibeksheel Party Coordinator Rabindra Mishra and the Election Commission on Wednesday.
The Pandey faction filed the case at the apex court against Mishra and the poll body saying that the party took action against them for no reasons.
Former party coordinator Pandey said that they moved the court alleging that the party took action against them at the direction of Mishra.
The party had expelled Pandey on December 21.
Earlier, Pandey had announced a 201-member Central Committee in the name of strengthening the party. The establishment faction, however, expelled Pandey taking this as an attempt to split the party.
