1. Where a Member State considers that to give effect to an alert entered in accordance with Article 26, 32 or 36 is incompatible with its national law, its international obligations or essential national interests, it may require that a flag be added to the alert to the effect that the action to be taken on the basis of the alert will not be taken in its territory. The flag shall be added by the SIRENE Bureau of the issuing Member State.
2. In order to enable Member States to require that a flag be added to an alert entered in accordance with Article 26, all Member States shall be notified automatically of any new alert of that category through the exchange of supplementary information.
3. If in particularly urgent and serious cases, an issuing Member State requests the execution of the action, the executing Member State shall examine whether it is able to allow the flag added at its behest to be withdrawn. If the executing Member State is able to do so, it shall take the necessary steps to ensure that the action to be taken can be carried out immediately.
