The principal area of reform would be auditing digital expenditure. GoI is pushing digital transactions that are inherently more traceable than physical ones, and offer clearer policy solutions through data analytics. GoI is itself processing much more data now, which makes oversight easier. But its auditor needs to build strength in big data to keep pace with the structural transformation of government finance. A case in point would be cash transfers to beneficiary accounts. These can club several government welfare schemes and reduce the need for individual physical audits. But the need for forensic auditing does not go away.
Of course, long-standing issues linger over transparency in the appointment of CAG, conflicts of interest in the selection being skewed in favour of the administrative service, and the lack of technical expertise at the top. Successive governments have upheld the independence of this constitutional authority in manners of their choosing. It would be in their larger interest to invest in institutional strength the Constitution has envisioned for CAG.
