Its chief spokesperson K C Tyagi said the Yadav faction wanted to delay a decision so as to deny it the electoral symbol of arrow in the Gujarat Assembly polls.
He had yesterday announced that the Bihar Chief Minister Nitish Kumar-led party will contest on its four to five traditional seats in the state.
Tyagi said a delegation, including the party's leader in the Rajya Sabha R C P Singh and Bihar government minister Rajiv Ranjan Singh besides him, will approach the Election Commission (EC) tomorrow to press for an early decision.
He has accused the Yadav faction, which claims support of a majority of the party's office-bearers, of filing "forged" documents before the EC to support its claim.
Almost all party MLAs and MPs, barring its Rajya Sabha members, have supported Kumar and submitted affidavits in his support.
The Yadav faction, which was opposed to Kumar's alliance with the BJP, has held its conventions and approached the EC to claim the party's symbol.
