Certificates of airworthiness, certificates of competency and licences, issued or validated by one Contracting Party and still in force, shall be recognised as valid by the other Contracting Party for the purpose of operating the agreed services on the routes specified in the Annex provided that such certificates or licences were issued or validated pursuant to, and in conformity with, the standards established under the Convention. Each Contracting Party shall have the right, however, to refuse to recognise, for the purpose of flights above its own territory, certificates of competency and licences granted to its own nationals by the other Contracting Party.
