"It is highly irresponsible on part of the BJP as an opposition party to disrupt the House in this manner. They (BJP) have said on record that they were behind the sting operation.
"I have asked them time and again to produce the original CD so that it could be sent for a forensic examination. No probe, let alone one by CBI, can be ordered into the case unless there is an FIR lodged in connection with it," Rawat said.
In Gairsain, the opposition party "created an uproar" in the state assembly on the opening day of a session forcing several adjournments of the proceedings.
Rawat said all options for a probe are open before the state government into the sting CD episode but the original CD is a prerequisite for it and the ball is in the BJP's court.
