In the Supreme Court Simon has appeared in two of the most important commercial appeals of recent times. He has the intellectual credibility and the experience required to impress at the highest level. He does not merely present his client’s case, but argues it to maximise the likelihood of persuading the tribunal. Simon has substantial trial experience and he particularly relishes the unique challenge of appellate advocacy. He does not take pointless points.” (Chambers & Partners, 2022) “His arguments are short, sweet and punchy. Calm under pressure and unfailingly courteous, he wins over the judge and allows witnesses to be drawn in only to fall into the trap. “He is self contained, on top of his brief and one of the few barristers who is more of an expert than the expert. He is fluent, persuasive, amusing and altogether very impressive indeed.' (Legal 500 2023) 'An outstanding advocate with an outstanding brain: when he speaks the Supreme Court listens carefully.' (Legal 500 2023)
