The Law+ Model

Law, Plus Everything Around It.

Every Omnia team pairs disputes counsel with people who know how governments, markets and the media move.

  1. Law

    Counsel before arbitral tribunals, the English courts and the International Court of Justice.

    Successfully contested the 2015 extradition of Rwanda’s intelligence chief in the English courts.

  2. Policy

    We advise ministries and international bodies, so we know how they think.

    Oral submissions for Albania at the ICJ’s climate change hearings, pro bono.

  3. Business

    Commercial judgement on value, risk and timing, with funders ready to share the cost.

    Sutton Energy’s multi-million dollar dispute over a West African port, settled.

  4. Communications

    Reputation handled as carefully as the case, in public and in private.

    Our report with Alaco on the charges against Alexander B. Cummings; ten days later, all were dropped.

We established Omnia to offer ‘more than law’, combining best-in-class legal skills with political and diplomatic insight.

FAQs

Before You Call Us.

Or ask a partner directly on +44 20 3915 6006.

Do you act for states or for investors?

Both. We have acted for dozens of governments and state entities, and for investors bringing treaty claims, so we know how each side thinks. We check for conflicts before taking on any new matter.

Can you join a dispute that is already under way?

Yes. The Gambia instructed us after an award had been made against it, and the award was annulled in full. We can take over a matter, join existing counsel or advise in the background.

Do you always try to settle first?

Wherever it serves you, yes: swift, amicable and discreet. When a fight is the right course, we see it through to an award and its enforcement, without compromise.

Who will work on my matter?

A partner leads every matter from the first call, with a small team chosen for it. Cherie Blair CBE KC leads many of our largest cases herself.

How are your fees structured?

Our lean model allows flexible fee structures, agreed with you at the start. We also work closely with third-party funders and insurers, who can share the cost and risk of a claim.

Where in the world do you work?

Everywhere our clients need us, from Accra to Almaty, Mongolia to Montenegro, under any governing law or set of arbitration rules. Our lawyers are admitted in eight jurisdictions.
