Extradition – Mutual Legal Assistance – Asylum

Cross-border criminal cooperation and international protection mechanisms—particularly extradition, mutual legal assistance, service of judicial documents, and asylum procedures—play a critical role in both the administration of criminal justice and the protection of fundamental rights. This section provides an overview of the legal safeguards, potential risks, and practical considerations associated with these mechanisms, with a particular focus on cases originating from Türkiye. It explains key concepts such as the principle of non-refoulement, politically motivated prosecutions, and the legal protections available under international and domestic law, while also outlining the steps individuals should take and the resources they may rely upon if they believe they are at risk abroad or upon returning to Türkiye.

Extradition and mutual legal assistance are two of the principal mechanisms through which states cooperate in the administration of criminal justice across national borders.

These mechanisms are designed to enhance the effectiveness of criminal law enforcement, facilitate the proper administration of justice, and ensure that criminal proceedings can be carried out efficiently on an international level.

In recent years, however, growing concerns have emerged regarding the misuse of these mechanisms for political purposes. In the context of Türkiye, extradition requests and mutual legal assistance requests based on broadly defined allegations of terrorism or membership of a criminal or terrorist organisation have, in many cases, been criticised as being politically motivated and directed against political opponents, journalists, academics, and members of civil society. Such practices undermine not only the fundamental rights of the individuals concerned but also mutual trust between states and the integrity of the international legal system.

Extradition refers to the surrender of an individual to another state for the purpose of criminal prosecution or the enforcement of a criminal sentence.

Mutual legal assistance, by contrast, involves one state carrying out specific procedural acts—such as taking witness statements, obtaining documents, or collecting evidence—on behalf of the judicial authorities of another state.

Because both mechanisms involve the exercise of sovereign powers across national borders, they must always be balanced against the safeguards provided by international human rights law.

Brussels Law Office closely monitors extradition and mutual legal assistance proceedings involving Türkiye or originating from Türkiye. We provide legal information, guidance, and advocacy for individuals affected by such proceedings, as well as for legal practitioners, policymakers, and other stakeholders.

This section explains the legal framework governing extradition and mutual legal assistance, the political offence exception, procedural safeguards, the potential consequences for affected individuals, and the practical steps that should be taken when confronted with such proceedings.

Even individuals living abroad who are not currently subject to an extradition request or mutual legal assistance proceedings should have a basic understanding of these mechanisms.

The effective protection of human rights depends not only on responding to violations after they occur, but also on preventing them through legal awareness and informed decision-making.

This section also provides practical guidance on how to deal with judicial documents and official notifications served abroad at the request of the Turkish authorities.
