International

In a globalized economic environment, business players are increasingly exposed to mechanisms of judicial cooperation between states.

International letters rogatory (CRI), European investigation orders (DEE), international arrest warrants, extraditions, cross-border investigations, asset freezes, seizure of banking information:

international criminal law procedures can have an immediate and considerable impact on the interests of a company, a regulated entity (bank, insurance company, investment fund, management company), a director, an executive, an investor, or even a shareholder.

Recognized expertise in international criminal law:

ECLIPSE, with over 20 years of experience among its partners and a practice exclusively dedicated to criminal law, has recognized expertise in international criminal law and international mutual legal assistance in criminal matters.

We are involved in all stages of proceedings involving foreign or Luxembourg judicial authorities in the context of judicial cooperation in criminal matters.

Strategic assistance for professionals in the financial sector:

We assist professional clients: financial sector players, fund managers, management companies, family offices, private banks, international investors, and company executives facing sensitive situations with high financial or reputational stakes in the context of international investigations or enforcement measures.


ECLIPSE is particularly involved in:

  • European Investigation Orders (EIOs)
  • International letters rogatory
  • Requests for international mutual legal assistance in criminal matters

Seizures, confiscations, and protection of rights

We also assist our clients in proceedings involving asset seizures, special confiscations, or in rem confiscations, which can deprive a client of the free disposal of their assets for many years.

Our firm also acts in cases of searches or seizures of documents/computer data ordered on the basis of a request for mutual legal assistance or a European Investigation Order, particularly when issues of professional secrecy are at stake. We ensure that only the elements strictly necessary for the investigation are included in the file, and refer the matter to the competent courts if necessary.

Rigorous analysis and proactive defense:

We analyze the legality of requests for international criminal cooperation and ensure that our clients’ fundamental rights are protected: confidentiality, proportionality of measures, and respect for procedural guarantees.

We also take proactive action with the Luxembourg or foreign authorities to anticipate or challenge the effects of these proceedings, in particular before the District Court’s Chamber of Council through the appropriate appeals.

Our in-depth knowledge of international criminal cooperation instruments, combined with our practice of criminal business law, enables us to offer a strategic, pragmatic, and tailor-made defense.

“Criminal Law Thursdays”: raising awareness and engaging with our clients:

Finally, ECLIPSE organizes monthly information and awareness sessions for its clients:

“Criminal Law Thursdays,” during which our team addresses specific topics, several of which are dedicated to international criminal proceedings, in light of the latest legal and case law developments.
