Constitutional court dismisses appeal against administrative decision regarding the revocation of a naturalized Austrian citizen's citizenship.

The Constitutional Court dismissed the applicant's appeal against the Federal Ministry of the Interior's decision to revoke his Austrian citizenship. The applicant, a naturalized citizen, argued that the revocation violated his constitutional rights and the principle of legal certainty. The court held that the administrative decision was lawful because it was based on a specific statutory provision allowing revocation for loss of loyalty to the Republic.
