While fulfilling his Constitutional obligations, the Comptroller & Auditor General examines various aspects of Government expenditure, which include among others:-
While conducting the audit of receipts of the Central and State Governments, the Comptroller & Auditor General satisfies himself that the rules and procedures ensure that assessment, collection and allocation of revenue are done in accordance with the law and there is no leakage of revenue which legally should come to Government.
After Independence, there has been a tremendous spurt in economic development and social welfare activities with the attendant increase in expenditure-revenue and capital - and in receipts and borrowings to match the expenditure.

Audit has evolved from mere accounting and regularity check to evaluation of the systems and the end results of the operations of government, testing their economy, efficiency and effectiveness.
