1. User charges that may be imposed by the competent charging authorities or bodies of each Party on the Designated Airline(s) of the other Party shall be just, reasonable, not discriminatory and equitably apportioned among categories of users. In any event, any such User charges shall be assessed on the Designated Airline(s) of the other Party on terms not less favorable than the most favorable terms available to any other Airline at the time the charges are assessed.
2. User charges imposed on the Designated Airline(s) of the other Party may reflect, but shall not exceed, the Full cost to the competent charging authorities or bodies of providing the appropriate airport, airport environmental, air navigation and aviation security facilities and services at the airport or within the airport system. Such Full cost may include a reasonable return on assets, after depreciation. Facilities and services for which charges are made shall be provided on an efficient and economic basis.
3. Each Party shall encourage consultations between the competent charging authorities or bodies in its Territory and the Designated Airline(s) using the services and facilities and shall encourage the competent charging authorities or bodies and the Designated Airline(s) to exchange such information as may be necessary to permit an accurate review of the reasonableness of the charges in accordance with the principles of paragraph 1 and 2 of this Article. Each Party shall encourage the competent charging authorities to provide users with reasonable notice of any proposal for changes in User charges to enable users to express their views before changes are made.
4. Neither Party shall be held in dispute resolution procedures pursuant to Article 18 (Settlement of Disputes) of this Agreement, to be in breach of a provision of this Article, unless (1) it fails to undertake a review of the User charge or practice that is the subject of complaint by the other Party within a reasonable time period; or (2) following such a review it fails to take all steps within its power to remedy any User charge or practice that is not consistent with this Article.
