A bench comprising Justices J Chelameswar and A M Sapre sought the details when Prashant Bhushan, counsel for Maudany, argued for clubbing of all the terror cases pending against his client in Bangalore.
"You both ascertain the facts and file affidavits," the bench said, adding that the affidavits should contain the fact as to whether the same set of persons were facing trial in all the nine cases.
Maudany is the prime accused in the Bangalore serial blasts that had occurred on July 25, 2008. Nine bombs had exploded in the city in which two people were killed and 20 injured.
In July last year, the court had granted one-month bail to Maudany on health grounds.
The court had also said the Karnataka government was at liberty to take all steps to ensure that he does not get in touch with witnesses in the case, including putting him under surveillance.
