The JPC has met not for a variety of reasons since April when the draft report was circulated to the members. Its last meeting took place in February this year.
"The meeting has been convened for September 23. The procedure states that after the draft report is circulated, a meeting is called to adopt it. I do not know whether some members could demand a discussion. But I am open to it," JPC Chairman P C Chacko told PTI.
The decision to convene the meeting of the 30-member panel came days after sharp differences between the government and the opposition over nomination of two Rajya Sabha members to the JPC.
