I came across this line about the duties of CAG in a book.
He satisfies himself about the wisdom, faithfulness and economy of the expenditure incurred.
What does this line mean? What does satisfy mean here, in what way.
CAG is Comptroller and Auditor General of India. His office is very powerful one and stands as the guardian of Indian Government. He looks after all the expenses made by Government of Union of India and States of India.
