The Comptroller and Auditor General of India (CAG), established under Article 148 of the Constitution, is the guardian of the public purse.
While legality focuses on whether expenditure is made according to law, propriety examines whether such expenditure is justified, prudent, and in the public interest.
Ensuring Legality of Expenditure
Ensures all expenditures are authorized by Parliament or State Legislature through Appropriation Acts.
Verifies that funds are drawn from the Consolidated Fund only under proper sanction.
Checks compliance with financial rules, codes, and delegated authorities.
Prevents unauthorized re-appropriation or excess expenditure beyond approved limits.
Eg- CAG’s audit of defence expenditure.
Ensuring Propriety of Expenditure
Examines whether expenditure is necessary, justifiable, and in the public interest – Ensures Responsible Use of Public Funds
Prevents Misuse – Evaluates waste, extravagance, or favouritism even if legally permissible.
Strengthens spirit of financial responsibility – Questions whether spending ensures value for money and meets ethical standards of governance.
Promotes a culture of fiscal morality and prudence in the use of public funds.
Strengthens Parliamentary Control and oversight with insights on ethical and prudent financial management
