The Brattle Group was instructed as quantum experts to Naftogaz in its dispute with Gazprom concerning unpaid gas transit fees. In June 2025 an ICC tribunal awarded Naftogaz USD1.37 billion, ruling that Gazprom had breached its contractual obligations by halting payments for the transit of Russian gas through Ukraine.

Brattle is one of the best firms there is. It has fantastic professionals at every level that are great on cross-examination. They are truly independent and are thought leaders.
The Brattle personnel I have been working with are elite in their field of expertise and are more than economic analysts. Rather, they are true litigation partners and close team members in our matters.
The Brattle experts I worked with were both deeply knowledgeable about the subject matter and industry and strategically sophisticated when it came to the dispute. They were more than just expert witnesses, they were partners in helping advance the client's case and business interests.
Brattle has some of the top financial economists and transfer pricing economists in the US working within the firm. It also has access and provides support services for a strong group of academic experts from top universities around the world. Brattle delivers strong value for our clients.
They are truly excellent, not only on the professional side but also very user-friendly. They are experts that can also explain the material to the client in a very simple and easy manner.
