Constitutional court dismisses appeal against administrative decision regarding the revocation of a naturalization certificate due to procedural defects.

The Constitutional Court dismissed the applicant's appeal against the Federal Ministry of the Interior's decision to revoke their naturalization certificate. The applicant argued that the revocation violated their right to a fair hearing and due process, while the state contended the certificate was obtained through deception. The court ruled that the administrative procedure was flawed but determined the substantive grounds for revocation were sufficient to justify the decision despite the procedural irregularities.
