Companies law: new rules require INC-20A certification and RD-1 filings with timelines and deemed approvals. The amendment requires the section 10A declaration to be filed in Form INC-20A and certified by a practising Company Secretary, Chartered Accountant or Cost Accountant; sectoral regulator approvals must be attached where applicable. It prescribes filing e-Form RD-1 (with fees and specified attachments) for change of financial year and for conversion of a public company into a private company, allows the Regional Director to call for further information via e-Form RD-GNL-5 with up to two re-submissions, provides timelines including deemed approval if no order is issued, and mandates filing the Regional Director's order with the Registrar in Form INC-28.
