"If another clone-faction is formed, our party will consider going to court," Rogozin said, adding that he saw the possibility as an attempt to begin an information war against Rodina.
He also said the entire story around several deputies leaving the faction had caused too much fuss.
"Deputies have left other factions before as well, but it never caused so much of a sensation."
Earlier, Duma Deputy Speaker Sergei Baburin was expelled from the Rodina faction "for actions aimed at splitting the faction and compromising its reputation."
Some of Baburin's supporters threatened to leave the faction following his expulsion.
Baburin and his supporters lodged a request with the Duma regulation committee to register their new faction, Narodnaya Volya (People's Will), named after the party he leads. However, Baburin said the committee refused to register the faction, saying that "since you ran for the 2003 parliamentary elections as members of the Rodina election bloc, your faction cannot have a different name."
Therefore, Baburin said, it was possible that there could be two Rodina factions.
Oleg Kovalev, the head of the parliamentary regulation committee, said the new faction led by Baburin might emerge as early as this week.
According to Kovalev, both the Rodina faction and Baburin's supporters said they wanted to be called Rodina. Kovalev admitted that one of the factions might be called Rodina (the Party of Russian Regions), and the other Rodina (People's Will).
