The appropriations allocated to expenditure for each financial year may not be used to pay expenditure for another financial year.
However, expenditure committed but not mandated at the close of the financial year is charged against the appropriations that must be carried over to the budget for the following financial year.
They may be paid until these appropriations are made available on the basis of the statement of outstanding commitments drawn up by the President of the Metropolitan Council, showing expenditure which, having been committed before 31 December of the previous year, has not been mandated before the end of the financial year. This statement serves as a provisional appropriation.
