A delegation of Congress leaders led by Majhi and comprising former minister Bijaylaxmi Sahu submitted a memorandum to CEO SK Lohani later.
Congress was keen to field Bandana Mangaraj, wife of deceased candidate Ajit Mangaraj in the by-poll.
The bypoll originally scheduled on April 17 was postponed following the death of Ajit Mangaraj on April 14 due to Covid-19.
However, behind the war of words, the main issue remains that Mahtab seems to be getting closer to the BJP after getting sidelined in the BJD.
As many as 15 candidates have filed nomination papers for bypoll to Pipili Assembly constituency scheduled on April 17.
The BJP on Thursday announced the candidature of Ashrit Pattanayak for the by-election to Pipili Assembly constituency in Puri district scheduled on April 17.
The by-election to Pipili constituency was necessitated after the death of the sitting BJD MLA and former minister Pradeep Maharathy on October 4 last year.
Senior leaders of Delang block BJD had recently decided in favour of projecting her as the party candidate for the by-poll.
