• (a) at least twelve States, including four States each with not less than 2 million units of gross tonnage, have expressed their consent to be bound by it, and

AMENDMENT OF LIMITS

Article XLVIII

1. Without prejudice to the provisions of article 47, the special procedure in this article shall apply solely for the purposes of amending the limits set out in article 9, paragraph 1 and article 14, paragraph 5.

2. Upon the request of at least one half, but in no case less than six, of the States Parties, any proposal to amend the limits specified in article 9, paragraph 1, and article 14, paragraph 5, shall be circulated by the Secretary-General to all Members of the Organization and to all Contracting States.

3. Any amendment proposed and circulated as above shall be submitted to the Legal Committee of the Organization (the Legal Committee) for consideration at a date at least six months after the date of its circulation.

4. All Contracting States, whether or not Members of the Organization, shall be entitled to participate in the proceedings of the Legal Committee for the consideration and adoption of amendments.

5. Amendments shall be adopted by a two-thirds majority of the Contracting States present and voting in the Legal Committee, expanded as provided in paragraph 4, on condition that at least one half of the Contracting States shall be present at the time of voting.

6. When acting on a proposal to amend the limits, the Legal Committee shall take into account the experience of incidents and, in particular, the amount of damage resulting therefrom, changes in the monetary values and the effect of the proposed amendment on the cost of insurance. It shall also take into account the relationship between the limits established in article 9, paragraph 1, and those in article 14, paragraph 5.

7. (a) No amendment of the limits under this article may be considered less than five years from the date this Convention was opened for signature nor less than five years from the date of entry into force of a previous amendment under this article.

(b) No limit may be increased so as to exceed an amount which corresponds to a limit laid down in this Convention increased by six per cent per year calculated on a compound basis from the date on which this Convention was opened for signature.

(c) No limit may be increased so as to exceed an amount which corresponds to a limit laid down in this Convention multiplied by three.

8. Any amendment adopted in accordance with paragraph 5 shall be notified by the Organization to all Contracting States. The amendment shall be deemed to have been accepted at the end of a period of eighteen months after the date of notification, unless within that period no less than one-fourth of the States which were Contracting States at the time of the adoption of the amendment have communicated to the Secretary-General that they do not accept the amendment, in which case the amendment is rejected and shall have no effect.

9. An amendment deemed to have been accepted in accordance with paragraph 8 shall enter into force eighteen months after its acceptance.

10. All Contracting States shall be bound by the amendment, unless they denounce this Convention in accordance with article 49, paragraphs 1 and 2, at least six months before the amendment enters into force. Such denunciation shall take effect when the amendment enters into force.

11. When an amendment has been adopted but the eighteen-month period for its acceptance has not yet expired, a State which becomes a Contracting State during that period shall be bound by the amendment if it enters into force. A State which becomes a Contracting State after that period shall be bound by an amendment which has been accepted in accordance with paragraph 8. In the cases referred to in this paragraph, a State becomes bound by an amendment when that amendment enters into force, or when this Convention enters into force for that State, if later.

12. For a State which expresses its consent to be bound by this Convention after the conditions for entry into force have been met, such consent shall take effect three months after the date of expression of such consent, or on the date on which this Convention enters into force in accordance with paragraph 1, whichever is the later.

DENUNCIATION

Article XLIX

1. This Convention may be denounced by any State Party at any time after the date on which it enters into force for that State Party.

2. Denunciation shall be effected by the deposit of an instrument of denunciation with the Secretary-General.

3. Denunciation shall take effect twelve months, or such longer period as may be specified in the instrument of denunciation, after its deposit with the Secretary-General.

CESSATION

Article LI

1. This Convention shall cease to be in force:

• (a) on the date when the number of States Parties falls below 6; or
• (b) twelve months after the date on which data concerning a previous calender year were to be communicated to the Director in accordance with article 21, if the data shows that the total quantity of contributing cargo to the general account in accordance with article 18, paragraphs 1(a) and (c) received in the States Parties in that preceding calender year was less than 30 million tonnes.

Notwithstanding (b), if the total quantity of contributing cargo to the general account in accordance with article 18, paragraphs 1(a) and (c) received in the States Parties in the preceding calendar year was less than 30 million tonnes but more than 25 million tonnes, the Assembly may, if it considers that this was due to exceptional circumstances and is not likely to be repeated, decide before the expiry of the above-mentioned twelve-month period that the Convention shall continue to be in force. The Assembly may not, however, take such a decision in more than two subsequent years.

2. States which are bound by this Convention on the day before the date it ceases to be in force shall enable the HNS Fund to exercise its functions as described under article 52 and shall, for that purpose only, remain bound by this Convention.
