Alongside these national events, INCEPT has developed a dedicated Methodology that maps the practices making a real difference across EU Member States. Here is what the research found.
Centralise and standardise at the national level. Countries that have established a dedicated central authority for handling EIOs consistently perform better. Having a single body responsible for receiving, assessing, and routing interception requests reduces delays, improves legal consistency, and builds trust with partner states. Equally important is the use of standardised templates and checklists, ensuring that every EIO contains the technical and legal information an executing authority actually needs.
Communicate early and often. One of the most impactful practices identified is straightforward: consult before you formally submit. Early informal discussions between issuing and executing authorities allow potential legal or technical obstacles to be identified and resolved in advance. When cases span multiple jurisdictions, EU bodies such as Eurojust and the European Judicial Network can play a vital coordination role.
Keep communications secure. Interception cases involve highly law enforcement-sensitive data, and the way authorities communicate must reflect that. Best practice points firmly towards encrypted, authenticated platforms such as e-CODEX for official EIO transmission, with every transfer of intercepted data accompanied by clear documentation of its source and intended use.
Invest in practical, continuous training. Judicial authorities benefit most from training that is hands-on and cross-border — combining real case studies, simulation exercises, and workshops involving practitioners from multiple Member States. Training should cover not only the procedural framework but also the technical realities of modern communications and the fundamental rights considerations at the heart of every interception decision.
Build consistency through Standard Operating Procedures. Well-designed SOPs give judicial authorities a reliable, documented framework for handling interception requests from start to finish — reducing errors, improving consistency, and making the entire process more transparent and accountable.
These workshops marked the final national training of the INCEPT project. The exchange will continue at the upcoming international event in Poznań, Poland on 19–20 April 2026, organised by Adam Mickiewicz University where participants and experts will build on these discussions at a cross-border level.
In the meantime, on the Incept accounts, we have been actively sharing weekly insights from the project's research and the issues discussed during the national events.
