In special cases, clearance on terms may be granted, for example restriction to one specific position. The King may issue regulations on the application of conditions for clearance. Section 8-7.Clearance of persons holding foreign citizenship A person holding foreign citizenship may be granted clearance following an individual overall assessment, provided that there are no reasonable grounds for doubting that the person is suitable for security clearance. In addition to the circumstances specified in section 8-4, the assessment shall emphasise the security-related significance of the home state, the person's ties with the home state and ties with Norway. When conducting clearance of a person holding foreign citizenship, special consideration shall be given to whether risk may be reduced through the application of conditions, for example position clearance. The King may issue regulations on clearance of persons holding foreign citizenship. Section 8-8.Revocation, downgrading or suspension of clearance If the clearance authority receives information giving grounds for doubting whether a cleared person is suitable for security clearance, the clearance authority shall consider revoking or downgrading the clearance, or suspend the clearance and implement further investigations. The authorisation authority shall be notified immediately of any decision to revoke, restrict or suspend a clearance. The clearance authority shall give the National Security Authority notice of the decision, which shall include a statement of reasons. Section 8-9.Authorisation The head of the undertaking constitutes the authorisation authority, and is responsible for security-related management and control of authorised persons. An authorisation interview shall be held before authorisation is granted. Authorisation may only be granted if the authorisation authority is not in possession of information giving reasonable grounds for doubting whether a person is suitable for access to classified information or critical national objects and infrastructure. The National Security Authority may require the undertaking to keep the National Security Authority informed of persons authorised. The King may issue regulations on authorisation, the duties of the authorisation authority and the duty of the undertaking to keep the National Security Authority informed of the identities of authorised persons.
