The court had said that despite lapse of over a month, the statement has not been recorded till date.
The judge, who is holding the trial in the 2G case on a day-to-day basis, had directed the CBI to expedite the matter and to take it up with the CMM so that Ammal's statement is recorded at the earliest.
The CMM Chennai was appointed as the commissioner for the purpose after the Supreme Court had on August 22 refused to exempt Ammal from deposing as a witness in the case.
The apex court, however, had exempted her from personal appearance in the special CBI court and had directed that she be examined in Chennai.
The apex court had passed the order on a plea filed by Ammal's daughter Selvi seeking a direction to exempt her mother from appearing before the trial court as prosecution witness on medical grounds.
