The Government may oppose, by decree in the Council of State, on the grounds of unworthiness or lack of assimilation, other than linguistic, the acquisition of French nationality by the foreign spouse within two years of the date of the receipt provided for in the second paragraph of Article 26 or, if registration has been refused, from the day on which the court decision admitting the legality of the declaration has become final.
The foreign spouse’s actual polygamous status or conviction for the offence defined in article 222-9 of the Penal Code, where this has been committed against a minor of fifteen years of age, shall constitute a failure to assimilate.
If the Government objects, the person concerned is deemed never to have acquired French nationality.
However, the validity of acts performed between the declaration and the decree of opposition may not be challenged on the grounds that the author was unable to acquire French nationality.
