Withdrawal of insolvency applications requires committee approval and is barred after resolution plan invitations begin. Section 12A regulates withdrawal of an application admitted under sections 7, 9 or 10 during the corporate insolvency resolution process. Withdrawal may be allowed only on an application made by the resolution professional with ninety per cent approval of the committee of creditors, and only in the prescribed manner. It is not permitted before constitution of the committee of creditors or after the first invitation for submission of a resolution plan has been issued. The Adjudicating Authority must pass an order within thirty days, or record reasons for delay in writing.
