When voting on the budget or an amending decision, the Metropolitan Council may vote on programme authorisations and commitment authorisations for unforeseen expenditure in the investment section and the operating section respectively. For each of the two sections, their amount may not exceed 2% of the actual expenditure for the section.
The failure to commit a programme authorisation or a commitment authorisation for unforeseen expenditure, noted at the end of the financial year, results in the authorisation lapsing.
Programme authorisations and commitment authorisations for unforeseen expenditure are allocated under the conditions provided for by decree.
