All processes must conform to the general IT-requirements of electronic messaging that ensure the successful reading, checking and recording of a process by the Union registry. All processes must conform to the specific process-related requirements set out in Chapters IV to VI of this Regulation.

The EUTL shall conduct automated checks for all processes to identify irregularities, hereinafter referred to as ‘discrepancies’, whereby the proposed process does not conform to the requirements of Directive 2003/87/EC and of this Regulation.

In case of processes completed through the direct communication link between the Union registry and the EUTL referred to in Article 5(2), the EUTL shall terminate any processes where it identifies discrepancies upon conducting the automated checks referred to in Article 66(2), and shall inform thereof the Union registry and the administrator of the accounts involved in the terminated transaction by returning an automated check response code. The Union registry shall immediately inform the relevant account holders that the process has been terminated.

In case of transactions completed through the ITL referred to in Article 5(1), the ITL shall terminate any processes where discrepancies are identified either by the ITL or the EUTL upon conducting the automated checks referred to in Article 66(2). Following a termination by the ITL, the EUTL shall also terminate the transaction. The ITL informs the administrators of the registries involved of the termination of the transaction by returning an automated check response code. If one of the registries involved is the Union registry, the Union registry shall also inform the administrator of the Union registry accounts involved in the terminated transaction by returning an automated check response code. The Union registry shall immediately inform the relevant account holders that the process has been terminated.

The Union registry and every other KP registry shall contain check input codes and check response codes to ensure the correct interpretation of information exchanged during each process. The check codes shall correspond to those contained in the Data Exchange and Technical Specifications provided for in Article 71.

Prior to and during the execution of all processes the Union registry shall conduct appropriate automated checks to ensure that discrepancies are detected and incorrect processes are terminated in advance of automated checks being conducted by the EUTL.

The EUTL shall periodically initiate data reconciliation to ensure that the EUTL's records of accounts, holdings of Kyoto units and allowances match the records of these holdings in the Union registry. For that purpose the EUTL shall record all processes.

The ITL periodically initiates data reconciliation to ensure that the ITL's records of the holdings of Kyoto units match the records of these holdings in the Union registry and every other KP registry.

If during the data reconciliation process referred to in paragraph 1, an irregularity, hereinafter referred to as ‘inconsistency’, is identified by EUTL, whereby the information regarding accounts, holdings of Kyoto units and allowances provided by the Union registry as part of the periodic reconciliation process differs from the information contained in the EUTL, the EUTL shall ensure that no further processes may be completed with any of the accounts, allowances or Kyoto units which are the subject of the inconsistency. The EUTL shall immediately inform the Central Administrator and the administrators of the relevant accounts of any inconsistency.

All transactions communicated to the ITL in accordance with Article 5(1) shall be final when the ITL notifies to the EUTL that it has completed the process.

All transactions and other processes communicated to the EUTL in accordance with Article 5(3) shall be final when the EUTL notifies to the Union registry that it has completed the processes.

The data reconciliation process referred to in Article 69(1) shall be final when all inconsistencies between the information contained in the Union registry and the information contained in the EUTL for a specific time and date have been resolved, and the data reconciliation process has been successfully re-initiated and completed.
