Artikel 4

1. Each Contracting Party shall have the right to revoke an operating authorization or to suspend the exercise of the rights specified in Article 2 of this Agreement by an airline designated by the other Contracting Party, or to impose such conditions as it may deem necessary on the exercise of these rights:
a) in any case where it is not satisfied that substantial ownership and effective control of that airline are vested in the Contracting Party designating the airline or in the nationals of such Contracting Party; or
b) in the case of failure by that airline to comply with the laws or regulations of the Contracting Party granting these rights; or
c) in case the airline otherwise fails to operate in accordance with the conditions prescribed under this Agreement.
2. Unless immediate revocation, suspension, or imposition of the conditions mentioned in paragraph 1) of this Article is essential to prevent further infringements of laws or regulations, such right shall be exercised only after consultation with the other Contracting Party.
3. In the event of action by one Contracting Party under this Article, the rights of the other Contracting Party under Article 13 shall not be prejudiced.
