Northamptonshire County Council's imposed emergency spending controls, as it deals with sever financial challenges.
The ruling bans all new spending, except for key services to safeguard the vulnerable.
The authority says it's at serious risk of not delivering a balanced budget - and will discuss the issue later this month.
Councillors have 21 days to discuss the implications of the section 114 notice and this is due to be addressed at the Full Council meeting on February 22nd.
The notice does not affect staff pay and the council will continue to meet its statutory functions.
