Extradition, mutual legal assistance and Interpol

We have acted in some of the most complex and high-profile extradition cases in recent times and can guide you through extradition proceedings no matter where you are.

In an increasingly globalised world, it is becoming more commonplace for people doing business in multiple jurisdictions to fall foul of foreign regulators or prosecutors. This can result in demands for business documents, bank statements and digital data to be handed over or extradition requests being issued for individuals.

If you find yourself subject to extradition proceedings, we can help. We have a detailed knowledge of extradition law and procedures, including the most effective arguments to resist requests.

As an international law firm with offices across Europe, the US and Asia-Pacific, together with our extensive network of professional contacts around the world, we are able to offer you complete global representation. Our lawyers have defended extradition requests from a multitude of countries worldwide including the Russian Federation, US, the UAE, Paraguay, India, Canada, Turkey and many EU countries.

Mutual Legal Assistance

Mutual legal assistance (MLA) is the process by which countries request cross-jurisdictional co-operation in obtaining evidence in one country to assist in a criminal investigation or proceedings in another country. Whether you are a business or an individual, this is a complex area to navigate and can place severe restrictions on your ability to carry on your business or to effectively challenge any foreign investigation or proceedings.

Our experienced lawyers can advise you on any available challenges to MLA requests, together with any associated risk of extradition. We can also assist if you are being requested to give evidence as a witness in foreign criminal proceedings.

Interpol Red Notices

With over 190 members, Interpol is the largest international policing organisation. Member countries often issue a Red Notice through Interpol whilst simultaneously making an application for an international arrest warrant in extradition proceedings.

Due to the nature of a Red Notice – a request to the law enforcement agencies of other member countries to locate and provisionally arrest a person pending extradition – it can have severe implications on your liberty and ability to travel. It can also cause considerable reputational damage and lead to adverse findings should you be subject to due diligence checks for personal and professional reasons.

Our lawyers have experience of successfully challenging Red Notices resulting in removal. Whatever your situation, we are on hand to offer strategic advice throughout extradition proceedings and devise creative solutions to help reach the desired outcome.
