Art. 11. 1. If one of the High Contracting Parties commits, in respect of any item of cultural property under special protection, a violation of the obligations under Article 9, the opposing Party shall, so long as this violation persists, be released from the obligation to ensure the immunity of the property concerned. Nevertheless, whenever possible, the latter Party shall first request the cessation of such violation within a reasonable time.
2. Apart from the case provided for in paragraph I of the present Article, immunity shall be withdrawn from cultural property under special protection only in exceptional cases of unavoidable military necessity, and only for such time as that necessity continues. Such necessity can be established only by the officer commanding a force the equivalent of a division in size or larger. Whenever circumstances permit, the opposing Party shall be notified, a reasonable time in advance, of the decision to withdraw immunity.
3. The Party withdrawing immunity shall, as soon as possible, so inform the Commissioner-General for cultural property provided for in the Regulations for the execution of the Convention, in writing, stating the reasons.
