2-Minute Revision
The Comptroller and Auditor General is India's supreme audit institution established under Articles 148-151 of the Constitution. Appointed by the President for six years or until age 65, the CAG enjoys security of tenure similar to Supreme Court Judges and can be removed only through impeachment.
The office combines Comptroller (pre-audit) and Auditor (post-audit) functions, though the latter dominates modern operations. CAG conducts three types of audits: financial audit examining accounts and transactions, compliance audit checking adherence to rules, and performance audit evaluating program effectiveness.
The audit jurisdiction covers Union Government, State Governments, Union Territories, autonomous bodies, and government companies with majority shareholding. CAG reports are submitted to President for Union matters and Governors for State matters, who table them in respective legislatures.
The Public Accounts Committee examines these reports and ensures follow-up action. Recent landmark reports on 2G spectrum, coal allocation, and Rafale deal have demonstrated CAG's crucial role in ensuring democratic accountability.
The institution has modernized through IT audits, environmental audits, and digital transformation while maintaining its core mandate of financial transparency and government accountability.
5-Minute Revision
The Comptroller and Auditor General represents one of India's most important constitutional institutions for ensuring financial accountability and transparency. Established under Articles 148-151, the CAG serves as the supreme audit institution with comprehensive mandate covering all levels of government.
Article 148 provides for CAG's appointment by President and security of tenure, Article 149 defines duties and powers, Article 150 empowers CAG to prescribe account formats, and Article 151 mandates report submission to President/Governors for legislative tabling.
The CAG is appointed by the President, typically from the Indian Audit and Accounts Service, for six years or until age 65. Constitutional safeguards for independence include removal only through impeachment (like Supreme Court Judges), salary charged on Consolidated Fund, and prohibition from post-retirement government positions.
The CAG conducts three types of audits: financial audit (examining accounts and transactions for accuracy and compliance), compliance audit (checking adherence to laws, rules, and procedures), and performance audit (evaluating efficiency, effectiveness, and economy of government programs).
This comprehensive audit mandate has evolved from traditional financial auditing to include IT audits, environmental audits, and specialized thematic audits addressing contemporary governance challenges.
The audit jurisdiction extends to Union Government departments, State Governments, Union Territory administrations, autonomous bodies receiving government grants, and public sector enterprises with majority government shareholding.
CAG reports form the foundation of parliamentary oversight through the Public Accounts Committee (PAC) and Committee on Public Undertakings (COPU), creating an accountability cycle from audit to legislative scrutiny to executive corrective action.
Landmark audit reports have significantly impacted Indian governance - the 2010 2G spectrum report exposed massive revenue losses leading to policy reforms, the 2012 coal allocation report contributed to transparent auction mechanisms, and recent reports on Rafale deal and GST implementation have influenced public discourse and administrative improvements.
The institution has embraced digital transformation through Computer Assisted Audit Techniques, data analytics, and online audit management systems while expanding into emerging areas like cybersecurity audits and digital governance assessments.
Current challenges include auditing complex financial instruments, public-private partnerships, and rapidly evolving technology platforms while maintaining traditional audit rigor and constitutional independence.
