By a decree in Conseil d'Etat, the Government may, on grounds of indignity or lack of assimilation other than
linguistic (Act no 2003-1119 of 26 Nov. 2003), oppose the acquisition of French nationality by the foreign spouse within
a period of one year after the date of the acknowledgement of receipt provided for in Article 26, paragraph 2, or, where
the registration was refused, after the day when the judgment which admits the lawfulness of the declaration has
entered into force.
(Act no 73-42 of 9 Jan. 1973) If there is an opposition by the Government, the party concerned shall be deemed to
have never acquired French nationality.
However, the validity of transactions concluded between the declaration and the decree that challenges it may not
be objected to on the ground that the maker was not allowed to acquire French nationality.
