David also participated in several landmark tax cases before the US Supreme Court, including the Barclays Bank, Boeing, and Goodyear cases. David has been described as “one of the top five tax controversy experts in the US”, and he received recognition as a “leading attorney” in US tax litigation by Chambers US, and as one of the world’s top 25 transfer pricing specialists.
