Convention for the Unification of Certain Rules for International Carriage by Air (Montreal, 28 May 1999)
Chapter III - Liability of the Carrier and Extent of Compensation for Damage
Article 24 - Review of limits
1. Without prejudice to the provisions of Article 25 of this Convention and subject to paragraph 2 below, the limits of liability prescribed in Articles 21, 22 and 23 shall be reviewed by the Depositary at five-year intervals, the first such review to take place at the end of the fifth year following the date of entry into force of this Convention, or if the Convention does not enter into force within five years of the date it is first open for signature, within the first year of its entry into force, by reference to an inflation factor which corresponds to the accumulated rate of inflation since the previous revision or in the first instance since the date of entry into force of the Convention. The measure of the rate of inflation to be used in determining the inflation factor shall be the weighted average of the annual rates of increase or decrease in the Consumer Price Indices of the States whose currencies comprise the Special Drawing Right mentioned in paragraph 1 of Article 23.
2. If the review referred to in the preceding paragraph concludes that the inflation factor has exceeded 10 percent, the Depositary shall notify States Parties of a revision of the limits of liability. Any such revision shall become effective six months after its notification to the States Parties. If within three months after its notification to the States Parties a majority of the States Parties register their disapproval, the revision shall not become effective and the Depositary shall refer the matter to a meeting of the States Parties. The Depositary shall immediately notify all States Parties of the coming into force of any revision.
3. Notwithstanding paragraph 1 of this Article, the procedure referred to in paragraph 2 of this Article shall be applied at any time provided that one-third of the States Parties express a desire to that effect and upon condition that the inflation factor referred to in paragraph 1 has exceeded 30 percent since the previous revision or since the date of entry into force of this Convention if there has been no previous revision. Subsequent reviews using the procedure described in paragraph 1 of this Article will take place at five-year intervals starting at the end of the fifth year following the date of the reviews under the present paragraph.
