Recognition of a security authorisation issued by an authority of a foreign power is governed by Section 62 of Act No 412/2005 on the protection of classified information and security of competence, as amended:

§ 62
Access to classified information on the basis of the recognition of a security authorisation issued by an authority of a foreign power

Access to classified information may be granted to a natural person who has been instructed, or to an entrepreneur, even in cases where the Office recognises a security authorisation issued by an office of a foreign power competent for the protection of classified information (hereinafter referred to as a "security authorisation"). The Office shall recognise security authorisations if provided for in an international treaty by which the Czech Republic is bound. The Office may also recognise security authorisations if recognition is in accordance with the foreign policy and security interests of the Czech Republic; there is no legal entitlement to such recognition. In the procedure referred to in the third sentence, the Office may request the opinion of the Ministry of Foreign Affairs and the relevant intelligence services; If the Office does not receive the requested opinion within 30 days from the date of receipt of the request for such opinion, the opinion shall be deemed to be positive.

An application may also be made through an office of a foreign power competent for the protection of classified information..

        The request referred to in paragraph 2 shall be accompanied by an official translation of the security authorisation or a certified copy thereof; such documents shall not be required where the application is made through an office of a foreign power competent for the protection of classified information, provided that the latter certifies, on the application or attestation which accompanies the application, that the applicant is in possession of the relevant security authorisation.
      6. Recognition pursuant to the first sentence of Section 62(1) of the Act shall be sent by the Office to the security authorisation holder within 10 days of the date of submission of the application; if the application pursuant to Section 62(2) of the Act is not submitted through the Office of a Foreign Power, the Office shall send the holder of the security authorisation the recognition of Section 62(1) within 20 days of the date of delivery of the application to the Office. Recognition pursuant to the second sentence of Section 62(1) shall be sent by the Office to the security authorisation holder within 60 days of the date of submission of the application; if recognition would not be in accordance with the foreign political or security interests of the Czech Republic, the Office will not comply with the request and will notify the applicant in writing within the same period.
