Will DA also pass order granting expressly, immunity from levy of interest and penalty by the AO as well as immunity from prosecution?

Ans. As per clause 6, subject to the provisions of clause 5, the DA shall not institute any proceeding in respect of an offence; or impose or levy any penalty; or charge any interest under the Income-tax Act in respect of tax arrears. This shall be reiterated in the order under section 5(2) passed by DA.
