I am a band 2 ranked individual in Chambers 2024 for Banking Litigation (London) and a ranked “leading practitioner” for banking litigation in Legal 500 2024. The 2024 Legal 500 testimonial states “Unlike some relatively senior partners who have become rainmakers for their firm rather than hands-on litigators, David Flack always thinks hard about the case himself and so managing the case becomes an on-going dialogue where two minds are definitely better than one. He has a collaborative approach, is the opposite of egotistic, and is one of the nicest, most positive people you could hope to meet. He is living proof that you do not need to be Mr Nasty as a litigator to get brilliant results”I was previously in-house litigation counsel for 8 years at UBS Investment Bank in London
