Mint today reported that under the current notice, the Sebi has no power to ask ICICI Bank top executive to step down but it can impose financial penalty. A maximum penalty of Rs 25 crore or three times the ill-gotten gains can be levied under Sebi rules, but in Chanda Kochhar's case, the quantum of the penalty may be at the discretion of Sebi's adjudicating officer, the report said.
