Commission Implementing Regulation (EU) 2025/1550 of 28 July 2025 establishing the technical specifications and other requirements for the decentralised IT system, referred to in Regulation (EU) 2023/1543 of the European Parliament and of the Council

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EU) 2023/1543 of the European Parliament and of the Council of 12 July 2023 on European Production Orders and European Preservation Orders for electronic evidence in criminal proceedings and for the execution of custodial sentences following criminal proceedings (1), and in particular Article 25(1), points (a), (b), (c) and (d) thereof,

Whereas:

(1) In order to establish the decentralised IT system referred to in Regulation (EU) 2023/1543, it is necessary to define and adopt technical specifications, measures and objectives for the implementation of that system.

(2) In accordance with Regulation (EU) 2023/1543, the decentralised IT system should be comprised of IT systems of the Member States and the Union agencies and bodies, and interoperable e-CODEX access points through which those IT systems are interconnected. Accordingly, the technical specifications and other requirements of the decentralised IT system should reflect this framework.

(3) In accordance with Regulation (EU) 2023/1543, the access points of the decentralised IT system should be based on authorised e-CODEX access points as defined in Article 3(3) of Regulation (EU) 2022/850 of the European Parliament and of the Council (2).

(4) Member States may opt to use the reference implementation software developed by the Commission as their back-end system in place of a national IT system. In order to ensure interoperability, both national IT systems and the reference implementation software should be subject to the same technical specifications and requirements set out in this Regulation.

(5) In order to mitigate potential technical issues related to the capacity and reliability of the decentralised IT system, it is necessary to establish a threshold for the volume of electronic evidence transmitted through that system. Following the system’s launch, the frequency and volume of such transmissions should be monitored, and the threshold should be adjusted, where appropriate, to maximise the system’s efficiency.

(6) In order to strengthen the interoperability and efficiency of the decentralised IT system the use of appropriate ETSI standards should be mandated. Future developments should be monitored, and, where necessary, the adoption of additional ETSI standards should be considered.

(7) Ireland is bound by Regulation (EU) 2023/1543 and is therefore taking part in the adoption of this Regulation.

(8) In accordance with Articles 1 and 2 of Protocol No 22 on the position of Denmark, annexed to the Treaty on European Union and to the Treaty on the Functioning of the European Union, Denmark is not bound by or subject to the application of this Regulation.

(9) The European Data Protection Supervisor was consulted in accordance with Article 42(1) of Regulation (EU) 2018/1725 of the European Parliament and of the Council (3) and delivered an opinion on 25 June 2025.

(10) The measures provided for in this Regulation are in accordance with the opinion of the committee established by Article 26 of Regulation (EU) 2023/1543,

HAS ADOPTED THIS REGULATION:
