The special delegation is appointed by decision of the representative of the State in the département within eight days of the dissolution, the definitive annulment of the elections, the acceptance of the resignation or the declaration that it is impossible to form the municipal council.
The special delegation elects its chairman and, if applicable, its vice-chairman.
The chairman, or, failing that, the vice-chairman, performs the duties of mayor. His powers end as soon as the new council is installed.
