Are there any mechanisms in place to ensure that state governments are held accountable for their use of public funds?
Yes, there are mechanisms in place to ensure that state governments are held accountable for their use of public funds. These include the following provisions:

1. Expenditure charged upon the Consolidated Fund of a State shall not be submitted to the vote of the Legislative Assembly, but nothing in this clause shall be construed as preventing the discussion in the Legislature of any of those estimates (Article 203(1)).
2. The Legislative Assembly shall have power to assent, or to refuse to assent, to any demand for a grant, or to assent to any demand subject to a reduction of the amount specified therein (Article 203(2)).
3. No demand for a grant shall be made except on the recommendation of the Governor (Article 203(3)).
4. As soon as may be after the grants under Article 203 have been made by the Assembly, there shall be introduced a Bill to provide for the appropriation out of the Consolidated Fund of the State of all moneys required to meet the expenditure charged on the Consolidated Fund of the State but not exceeding in any case the amount shown in the statement previously laid before the House or Houses (Article 204(1)).

These provisions require the state government to present its financial plans and budget proposals for approval by the Legislative Assembly, allowing for discussion, scrutiny, and potential amendments. This process helps to ensure transparency and accountability in the use of public funds by state governments.
