1. Introduction
In recent years, the fight against transnational crimes has determined an increase in
the number of transnational criminal proceedings, which has brought about significant
changes in transnational evidence law. The possibility of gathering evidence overseas
and using it before domestic courts has become all the more relevant, especially from
the viewpoint of accurate judicial ascertainment. In particular, significant steps forward
have been taken to strengthen judicial cooperation in the gathering of evidence, which, in
turn, has highlighted the need to improve the protection of human rights in transnational
criminal justice2. Indeed, “being subject to a transnational criminal procedure should
not affect the right to defence and should not result in a lowering of the procedural rights
of the accused”3.
In this light, this paper addresses the problems related to the gathering and use of
testimonial evidence obtained in other countries from the perspective of a participatory
approach to transnational criminal justice. Indeed, taking evidence overseas can hamper
the defendants’ right to confrontation if they are not duly given an opportunity to
challenge and question witnesses testifying against them.
This analysis will preliminarily consider whether Article 6(3)(d) ECHR, which
enshrines the right to confrontation, is also relevant in transnational criminal
proceedings4. Furthermore, we will investigate whether the taking of testimonial
evidence in other countries meets the requirement set out by this fundamental provision.

ECtHR’s Case-Law, in Utrecht Law Review, vol. 9, no. 4, 2013, p.128. In light of this, a current definition of transnational
criminal proceedings depicts them as “concerned with the relationship between the requesting and the requested
states (international dimension), as well as with the relationship between the requesting or the requested State
on the one hand and the individual (defendant, victim, third party) on the other (internal dimension)”. M. B,

procedures and those based on mutual recognition – rely upon a human rights-oriented perspective and on a
participatory understanding of the gathering of transnational evidence. S. R, Audi Alteram Partem in
