Monckton Chambers (Chambers of Tim Ward QC and Philip Moser QC)


Jon Turner QC is widely recognised as one of the Bar’s foremost litigators in competition law, EU law, and telecoms and utilities regulation and has been involved in many of the leading cases in these areas in recent years. In addition he is an established and highly-regarded litigator in the fields of commercial, public and administrative, and environmental law. He is the joint first ranked leading silk in The Legal SOO’s EU and competition category and a ‘star performer’: Turner ‘combines approachability with prodigious intellect and a willingness to get stuck in’. Turner’s ‘ability both to be part of, and ultimately, to lead a team into court’ made him ‘one of the foremost QCs at the competition Bar’. ‘Jon Turner QC is ‘a blessed barrister’, according to clients. As well as being ‘extremely bright and brilliant at recalling evidence,’ he enjoys the untrammeled respect of both peers and clients’. Publications of note include: contributor to Bellamy and Child’s ‘Common Market Law of Competition’, 4th ed and supplement (chapter on Civil Remedies); contributor to supplement to Bellamy and Child’s Common Market Law of Competition, 3rd ed (Chapters on Article 86, Enforcement and Procedure, Vertical Agreements affecting Distribution and Supply); consulting editor of Bellamy & Child’s ‘European Union Law of Competition’ update to the seventh edition.

London Bar


Within: Leading Silks

Jon Turner QC - Monckton ChambersThe master of competition law, if he does not know it, it is not worth knowing.

Within: Competition

Monckton Chambers is 'a formidably strong set, with a critical mass of highly regarded members in this specialism'. The set has members instructed in all manner of competition cases, including the most high-profile cartel investigations, follow-on damages claims, and litigation over standard essential patents. Paul Harris QC  represents the claimants in the Merricks collective action case, in which a litigation funder-backed class representative seeks to bring a claim against Mastercard concerning interchange fees, nominally on behalf of every UK resident who purchased anything from a Mastercard-accepting retailer in a sixteen year window. Jon Turner QC is defending Google in an abuse of dominant position claim brought by price comparison website Foundem; the claim concerns the placement of competing price comparison websites on Google's search engine. More unusually, on behalf of the States of Jersey, Kassie Smith QC carried out a review into the Jersey Competition and Regulatory Authority, after the Jersey Royal Court overturned a finding that a fuel supplier abused its dominant position at Jersey airport.
