Timely remedial action for revenue audit objections required, with complete proforma reports and appropriate statutory reassessment where needed. Where Revenue Audit or C&AG draft para objections are accepted by Commissioners, remedial action must be completed immediately and proforma reports in Part 'A' and 'B' must be fully and correctly completed and sent to the Board within the prescribed timeline, with dates of receipt and dispatch recorded; action should be taken under section 147 or 263 where detailed examination is required and section 154 used only for mistakes apparent from record.
