Article 29 establishes a procedure that may be followed by the Contracting States in the

event that one of the Contracting States considers that a substantial change in the domestic laws of the other Contracting State relevant to the Convention has been made. In such a case, the first-mentioned Contracting State may make a request to the Contracting State making the change in law for consultations with a view to determining the possible effect of such change on the balance of benefits provided by the Convention and, if appropriate, to amending the provisions of the Convention to arrive at an appropriate balance of benefits. This provision is intended to provide a procedure in a case where changes to the law of one of the Contracting States may alter significantly the legal application of the Convention as intended by the Contracting States as of the date of signature. In the event that these consultations lead to an agreement regarding amendments to the Convention, any such amendments would, of course, require a protocol or new treaty which would be subject in the United States to Senate advice and consent to ratification.

The request for consultations must be in writing, and as a communication from one Contracting State to the other should be made through diplomatic channels. The requested Contracting State shall enter into consultations with the Contracting State making the request within three months of the date of receipt of the request.
