In what ways does the Indian Constitution ensure transparency and accountability in government expenditure through these articles?
The Indian Constitution ensures transparency and accountability in government expenditure through the following provisions:

1. Article 115 requires the President to lay before both Houses of Parliament another statement showing the estimated amount of supplementary, additional or excess expenditure if it is found that the allocated amount for a particular service is insufficient, there is a need for new services not contemplated in the annual financial statement, or when any money has been spent on a service during a financial year in excess of the granted amount.
2. Article 116 allows the House of the People to make grants in advance for a part of any financial year pending the completion of the voting of such grant and passing of the law in relation to that expenditure, ensuring timely allocation of funds for crucial services.
3. Articles 112, 113, and 114 ensure transparency and accountability by mandating the annual financial statement, the procedure for voting on demands for grants, and the passing of a law for the appropriation of moneys out of the Consolidated Fund of India to meet such expenditure or grant.

These provisions enable the Parliament to monitor government expenditure closely, ensuring that public funds are utilized efficiently and effectively for the intended services.
