From the table it also appears that in some states (Belgium, France and Italy) only naturalised citizens or those who acquired the nationality after birth in another way (declaration or option) can be deprived of their nationality because of terrorist activities. In France, citizens can be deprived of their nationality until 15 years after naturalisation. In Belgium a similar restriction in time (10 years) applied until 2015. In Austria, Denmark, Germany, Finland and the Netherlands, citizens by birth can be deprived of their nationality. This also applies to the revocation ground most used in the UK (conducive to the public good). Four of the six states having the power to revoke the nationality of citizens by birth may take that decision without a previous criminal conviction. A previous conviction is required in Belgium, France and Italy but also in Denmark and Finland. 34 Art. 14 (2) Rijkswet op het Nederlanderschap.
