Singh, who had earlier struck a defiant note saying CBI has no authority to question a Constitutional functionary having powers of a civil court, without Centre's sanction, made the statement before a two-member CBI team at his NCSC office in the Lok Nayak Bhavan here.
Buta Singh's son, Sarobjit, was arrested on July 31 by CBI for allegedly demanding a bribe of Rs. one crore from a Nashik-based contractor to close an atrocity case against him pending before the Commission headed by his father.
The High Court had on August 26 sought response from the CBI on a petition filed by Singh, who had accused the probe agency of "illegally" summoning him.
Singh, who had approached the High Court on August 25, had also contended that he holds a post of Cabinet rank and the CBI cannot question or interrogate him without taking the Centre's sanction.
