If the Board finds on the basis of information at its disposal in accordance with the provisions of this Convention that a Party which has submitted an estimate under paragraph 1 (f) of article 19 has not limited opium produced within its borders to licit purposes in accordance with relevant estimates and that a significant amount of opium produced, whether licitly or illicitly, within the borders of such a Party, has been introduced into the illicit traffic, it may, after studying the explanations of the Party concerned, which shall be submitted to it within one month after notification of the finding in question, decide to deduct all, or a portion, of such an amount from the quantity to be produced and from the total of the estimates as defined in paragraph 2 (b) of article 19 for the next year in which such a deduction can be technically accomplished, taking into account the season of the year and contractual commitments to export opium.
