Artikel 4

1. Each Contracting Party shall have the right to suspend the exercise of the rights specified in Article 2 of the present Agreement by the airline(s) designated by the other Contracting Party, or to revoke the operating authorization, 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 said airline(s) are vested in the Contracting Party designating the airline(s) or in its nationals, or
b) in the case of failure by said airline(s) to comply with the legislation or regulations of the State of the Contracting Party granting these rights, or
c) in the case the airline(s) otherwise fail(s) to operate in accordance with the conditions prescribed under the present Agreement.
2. Unless immediate suspension, revocation or imposition of the conditions mentioned in paragraph 1 of this Article is essential to prevent further infringements of legislation or regulations, such right shall be exercised only after consultations with the other Contracting Party. Unless otherwise agreed by the Contracting Parties, such consultations shall begin within a period of sixty (60) days from the date of receipt of the request.
