Union Law Minister M Veerappa Moily said the Centre was seized of the matter on the formation of a committee or mechanism to look into all issues and concerns of all regions in Andhra Pradesh.
"The terms of reference are under preparation and not yet finalised," Moily, who is also in charge of party affairs in the state, said in a statement.
Congress leaders should "withdraw" themselves from the Joint Action Committee, he said and warned that "any violation of the party discipline will be seriously dealt with".
Moily also asked party leaders not to rush to the press on a "sensitive" issue like this to precipitate the matters and disrupt the normalcy restored after the discussions held with all political parties and leaders by the Union Home Minister P Chidambaram on January five.
The statement comes close on the heels of JAC extending its deadline to February seven for getting the resignations of legislators accepted following Chidambaram's announcement that a committee on the issue will be appointed by next week.
There were expectations that the Centre will announce the mechanism tomorrow. (
