The Bombay High Court on Wednesday sought to know from CBI if sanction was required to prosecute former Maharashtra Chief Minister Ashok Chavan on corruption charges in the Adarsh Housing scam case.

Justice Sadhana Jadhav raised the query while hearing a revision petition filed by CBI seeking permission to delete Chavan's name from the FIR in the case following refusal of grant of sanction to prosecute from Maharashtra Governor Kateekal Sankaranaryanan.
