Article 16U.K.Obligation to inform
1.The competent authority in the executing State which receives the EIO shall, without delay, and in any case within a week of the reception of an EIO, acknowledge reception of the EIO by completing and sending the form set out in Annex B.
Where a central authority has been designated in accordance with Article 7(3), this obligation is applicable both to the central authority and to the executing authority which receives the EIO from the central authority.
In the cases referred to in Article 7(6), this obligation applies both to the competent authority which initially received the EIO and to the executing authority to which the EIO is finally transmitted.
2.Without prejudice to Article 10(4) and (5) the executing authority shall inform the issuing authority immediately by any means:
(a)if it is impossible for the executing authority to take a decision on the recognition or execution due to the fact that the form provided for in Annex A is incomplete or manifestly incorrect;
(b)if the executing authority, in the course of the execution of the EIO, considers without further enquiries that it may be appropriate to carry out investigative measures not initially foreseen, or which could not be specified when the EIO was issued, in order to enable the issuing authority to take further action in the specific case; or
(c)if the executing authority establishes that, in the specific case, it cannot comply with formalities and procedures expressly indicated by the issuing authority in accordance with Article 9.
Upon request by the issuing authority, the information shall be confirmed without delay by any means capable of producing a written record.
3.Without prejudice to Article 10(4) and (5) the executing authority shall inform the issuing authority without delay by any means capable of producing a written record:
(a)of any decision taken pursuant to Articles 10 or 11;
(b)of any decision to postpone the execution or recognition of the EIO, the reasons for the postponement and, if possible, the expected duration of the postponement.
