He has particular experience, both as an advisor and advocate, of large-scale litigation relating to pensions, commercial and company litigation, financial services, trusts, insolvency, professional negligence and property disputes.

Previous editions say “he is a very charming opponent, but steely when needed”. “He is clear-headed, very practical, resourceful and has strong advocacy skills” (Chambers & Partners 2018). Sebastian also has “a sharp intellect and a fantastic manner with clients.” (The Legal 500 2017)
