Where the outcome of an application for annulment appears to be manifestly necessary, the President of the Examining Magistrates’ Chamber shall rule on this application, in accordance with the provisions of Article 199, without the two members of the Chamber being present.
If the necessary decision consists of the annulment of the acts or documents of the proceedings, it may, if the public prosecutor agrees, be made by order without the hearing provided for in the same article 199.
The author of the application for annulment may, however, request that it be examined by the investigating chamber.
