Richard Sage

Call 2006

“Very hardworking and will dedicate himself to a case. He is always available to provide a guiding hand and his advice is invaluable.”
(Legal 500, 2021)

Product Liability

Richard has a busy and successful practice in the field of product liability law, complemented by his extensive knowledge of the law relating to construction, insurance and professional negligence. Richard has regularly appeared in the High Court and the Court of Appeal, frequently acting without a leader against QCs and other leading highly-ranked juniors.

Richard was led by Alexander Antelme QC, alongside David Myhill, in the ground-breaking metal-on-metal hips litigation (Gee v DePuy International [2018] EWHC 1208), and continues to act in relation to similar disputes in other jurisdictions.

Richard is regularly instructed on cases involving complex engineering evidence, reflecting his background in construction claims and his MSc in construction law. He is highly sought after in cases where expert scientific evidence is central to the claim.

Richard’s product liability practice is complemented by his considerable experience in property damage claims. He was junior counsel in one of the leading Court of Appeal decisions on proving causation in property damage claims (Milton Keynes BC v Nulty [2012] EWCA Civ 15). In 2021, Richard was junior counsel to one of the defendants in the Clandon Park litigation. This was one of the largest TCC claims in 2021, involving a nationally important stately home that was destroyed in a fire allegedly caused by a defective lift installation.

Richard has invaluable experience working as part of a wider team on substantial cases, group actions and in multi-party litigation arising out of defective products. For example, Richard has acted for insurers of multiple defendants facing hundreds of claims for installing allegedly defective cavity wall insulation in homes across the UK, with a substantial combined value. He has had extensive involvement representing the manufacturers of metal-on-metal hips in resisting a large volume of claims.

Richard’s practice also means he is very familiar with coverage disputes relating to product liability claims. He regularly advises on the scope of indemnity provisions, exclusions, warranties, and on issues such as misrepresentation and non-disclosure.

Richard is recommended in both Chambers and Partners and the Legal 500 for his product liability work. According to the latest edition of Legal 500, “Richard is very thorough, and quickly on top of the detail of a case, no matter how technical and complicated. He is efficient, responsive, very approachable and good with clients and experts” (2021). According to the latest edition of Chambers and Partners, “His attention to detail is very good and he always thinks through to the end game. He is thoroughly easy to deal with, very approachable and very good with clients” (2021); and “He is thorough, prompt and punctual. He’s approachable and clearly explains complex issues” (2021).
