International criminal law (ICC & ICJ)

Representation before the International Criminal Court and the International Court of Justice.

What this covers
  • Representation in ICC investigation and pre-trial stages
  • Written procedure and oral submissions
  • ICJ contentious proceedings
  • Corporate disclosure and internal investigation
  • Risk assessment for legal entities and officers
  • Coordination with national proceedings and regulators

The International Criminal Court and the International Court of Justice sit at the centre of a body of law that states write but cannot enforce alone. We represent legal entities and their officers before those courts — in investigations, in written proceedings, and in hearings.

Proceedings in The Hague combine elements of common law and civil law, sit under a statute that is not the Rome Statute, and are heard in two languages with a five-year bench. Case preparation therefore starts earlier and runs differently than a domestic file.

We build the strategy around the specific posture of the file — investigation, confirmation of charges, trial or enforcement of a judgment — and around the corporate interests that sit behind it: liability, disclosure, and the consequences for the business.

FAQ

Frequently asked

Do you represent legal entities or individuals before the ICC?

Both, and most often the legal entity and its officers at the same time. Corporate exposure, disclosure and the interests of the individual are usually one problem, not three.

At which stage should we come to you?

Before a referral is made, if that is still in your hands. Advice given at the document stage can shape the referral; after it, the options are mostly about mitigation and representation.

How do ICJ proceedings differ from ICC proceedings?

The ICJ hears disputes between states; the ICC prosecutes individuals. The ICJ works from the written pleading and the record; the ICC works from an investigation and disclosure. Different rules, different deadlines, different remedies.
