1. The customs authorities shall, at the request of the declarant, invalidate a declaration already accepted in the following cases:
where they are satisfied that the goods are immediately to be placed under another customs procedure;
where they are satisfied that, as a result of special circumstances, the placing of the goods under the customs procedure for which they were declared is no longer justified.
However, where the customs authorities have informed the declarant of their intention to examine the goods, a request for invalidation of the declaration shall not be accepted before the examination has taken place.
2. The declaration shall not be invalidated after the goods have been released. The measures designed to amend non-essential elements of this Regulation, by supplementing it, laying down exceptions to the first subparagraph of this paragraph, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 184(4).
