Telangana Congress leaders alleged that the JAC was acting at the behest of Telangana Rashtra Samiti (TRS) chief K Chandrasekhara Rao.
Earlier, the JAC rejected the terms of reference of Srikrishna panel as they include considering the demand for maintaining Andhra Pradesh in its present form.
JAC had asked all elected representatives to quit by Monday evening, Feb 15, failing which a series of protests would be launched against them.
Congress MP Ponnam Prabhakar advised JAC convenor M Kodandaram not to work like a "postman" of the TRS.
Prabhakar asked him to take into consideration the views of all parties before taking a decision.
Only two of 50 Congress legislators from Telangana have submitted their resignations to the Assembly Speaker, who has not yet accepted them.
The Speaker, however, accepted the resignations of all 10 TRS legislators as well as one each of the Telugu Desam Party (TDP) and the Bharatiya Janata Party (BJP). One legislator of the Praja Rajyam Party has also submitted his resignation.
The Congress leaders said they would not resign and instead decided to write a letter to party president Sonia Gandhi to revise the terms of reference of Srikrishna committee.
