The Public Accounts Committee is often described as the watchdog of the watchdog's reports. Examine its role in ensuring financial accountability of the executive, and suggest measures to address delays in its functioning.

The CAG audits the executive, and its reports are laid before Parliament under Article 151. They become real accountability only when the Public Accounts Committee (PAC) examines them, which is why it is called the "watchdog of the watchdog's reports". It is India's oldest parliamentary committee (1921) and a strong check on spending. Chronic delays, however, weaken it.

Role in ensuring financial accountability

• Scope-of-demand test: It examines the Appropriation Accounts, Finance Accounts and CAG reports to check that money was spent as Parliament authorised. It also probes losses, wasteful expenditure and tax-administration lapses [2].
• Bipartisan scrutiny: It has up to 22 members (15 from Lok Sabha, 7 from Rajya Sabha), and ministers are barred from membership. By convention since 1967, an Opposition member chairs it, which Speaker Om Birla called a sign of democratic "maturity" [1][2].
• Audit follow-through: Ministries must send Action Taken Notes (ATNs), vetted by the CAG, within three months of a report being tabled [5].

Limitations and causes of delay

• Advisory and post-mortem: Its recommendations are not binding, and by the time it acts the money has already been spent [2].
• Backlog: Some PAC reports have been pending for 15–20 years [1].
• Executive non-compliance: The PAC's 105th Report (1995-96) set a four-month ATN deadline. Yet on 30 June 2013, the Finance Ministry counted 815 pending ATNs while the CAG counted 722. Railways (169) and Defence (143) were among the largest defaulters [3]. ATNs on 48 paragraphs from four ministries were still pending in December 2021 [4].
• Annual re-election of Lok Sabha members breaks the continuity of long inquiries [2].

Measures to address delays

• One shared digital tracker for every audit paragraph, visible to ministries, the CAG and the PAC, to end mismatched counts. AI and data analytics can flag unusual spending and help choose which paragraphs to examine, as Birla urged [1][3].
• Consequences for defaulters: The Department of Expenditure should publish overdue ATNs ministry by ministry, like the UK's Treasury Minutes, and fix responsibility on Secretaries.
• Targeted hearings for departments with the most pending ATNs, such as Railways, Defence and the tax boards [3].
• Floor time in the House to debate PAC reports and the government's Action Taken Reports.
• Longer member tenure so inquiries keep continuity.

The PAC turns CAG audits into political answerability, but late findings have little deterrent value. Time-bound ATNs, technology-enabled tracking and steady follow-up in the House can make it a timely guardian of the public purse. This would complete the constitutional chain of accountability under Article 151 and match SDG 16's goal of accountable institutions.
