 After the constitutional reform of 2003 it became an overseas collectivity while retaining the title "departmental collectivity" of Mayotte.Mayotte became an overseas department of France ("département d'outre-mer", DOM) on 31 March 2011 following the result of the March 2009 Mahoran status referendum, which was overwhelmingly approved by around 95% of voters.Becoming an overseas department will mean it will adopt the same legal and social system as used in the rest of France.
