Revocation of French citizenship of a citizen with double nationality, grounded on participation in a criminal conspiracy to commit an act of terrorism.
Art. 8 ECHR
1. Deprivation of citizenship, imposed by French authorities on plaintiffs, does not amount to a disproportionate interference with the right to private and family life.
2. The decision to deprive an individual of his/her citizenship does not amount to a disproportionate sanction in case he/she has double citizenship. As a matter of fact, double citizenship ensures that the individual will not become stateless.
3. The deprivation of citizenship provided by the French Civil Code is not a criminal sanction. As a consequence, the deprivation of citizenship of a person who has already been convicted on a terrorist offence cannot be considered as bis in idem.
