The ministry also reiterated ban on holding meetings and conferences in five-star hotels saying the guidelines on cutting non-plan expenditure should be "strictly" followed.
In a communication to all ministries and departments, the Finance Ministry said that proposals for approval of Expenditure Secretary or Cabinet Secretary are to submitted at at least one month in advance.
The instruction has been issued after it was found that timelines for submission of cases were not adhered to and also a large number of cases were being referred to the Department of Expenditure seeking post-facto approval.
The government has put in place measures aimed at cutting non-plan spending by 10 per cent as part of fiscal discipline roadmap.
