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 shall be charged against the appropriations which 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 Lyon 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 is equivalent to the provisional opening of appropriations.
