Justin Mort KC specialises in high value construction disputes with particular interest in and expertise in (1) energy, (2) infrastructure and (3) process engineering projects.
Justin is recommended for Construction in both Chambers Global and Legal 500. He is also recommended in the Legal 500 for Middle East (construction) and for international arbitration. Comments in the current editions of these directories include:
“Dedicated 100% to the matter before him. He drills down the facts like no other QC. His work ethic and focus is commendable. He made himself available so can prepare on short notice and put in a stellar show at the hearing.” (Legal 500: Middle East, construction)
“Justin is a persuasive advocate who tears through detail to get to the points that really matter. His advocacy is exceptional – clear, cogent and compelling.” (Legal 500: London Bar, construction)
“Simplifies the complicated. Knows his stuff. Great to work with.” (Legal 500: international arbitration)
“He is regularly called upon in international disputes regarding energy projects.” (Chambers Global: construction)
“His attention to detail is phenomenal and his cross-examination style formidable.” (Chambers Global: construction)
These comments, and similar ones appearing in the directories over the last 20+ years, are both accurate and apposite: Justin has an unparalleled reputation as a successful trial advocate, cross-examiner, strategist and lawyer.
Justin is a huge team player. He is immediately responsive to client demands and questions at any time of day. He ensures that the wider client team are fully engaged in his proposed trial strategy. Uniquely he provides detailed notes of his proposed oral submissions and cross examination to the client well in advance of any hearing for comment, and in order to ensure that the client team can better follow and appreciate his method during any hearing. His working habits (typically starting at 4am or 5am London time) correspond well with clients based in time zones located to the east of London such as in the Middle East or in China.
Justin’s innumerable reported cases arising from court proceedings, particularly in the TCC, and the original and ingenious legal arguments that he has deployed in fighting them, together constitute a formidable contribution to the law governing construction claims and arbitration.
Justin has extensive experience of disputes, determined in arbitration, litigation or by other means, arising out of major infrastructure projects, including those with a significant IT element. Some recent examples, from both the UK and international arbitration, include:
Acting for a contractor in a series of disputes (in arbitration) subject to UAE law, including claims for variations and extension of time.
