    Justin Mort QC specialises in disputes arising out of construction, energy, infrastructure and process engineering projects. He is recommended in Chambers and Partners in the “Construction” (Band 1) and “Energy and Natural Resources” sections. He is also recommended in Chambers and Partners Global and the Legal 500.

    He has an unparalleled reputation as a successful trial advocate, strategist and lawyer. Comments in the directories include: “Justin is a fantastic lawyer as he gets straight into things and works incredibly hard on the detail. He can rip apart cases that need a detailed analysis”, “A strong, forceful advocate who is completely at home in the TCC” and “singled out for the strength of his intellect, and his vast knowledge of the technicalities of construction law”. He has recently worked on claims arising from a variety of energy projects including the construction of a wind farm in Scotland (delay claim), Pembroke power station (termination and final account dispute), a gas power station in Singapore, a hydro-electric dam in Malaysia (unforeseen grounds conditions claim) and a waste to energy power plant in England.

    Lately he has worked on disputes arising in Dubai, Hong Kong, Singapore, Malaysia, Thailand, Ukraine, Kazakhstan, Venezuela, Gibraltar, Denmark, St Lucia, and Zambia as well as the UK. Infrastructure projects that Justin has worked on include major works for the supply of electricity, the maintenance of trunk roads and other transport projects, and numerous PFI projects. Justin is presently working on two (unrelated) disputes arising out of the 2012 London Olympics. Justin taught construction and arbitration law as part of the LLM at the Centre of Commercial Studies at Queen Mary College. He has appeared in numerous reported decisions concerning the interpretation and application of the Arbitration Act 1996.  He has detailed knowledge and experience of the principal arbitration rules.

    Justin also specialises in injunctive proceedings. He has recently acted for a party seeking an injunction to prevent a firm of solicitors from acting against their client, a mandatory injunction for return of takeover packages removed to Italy (Alstom v SOMI), an anti-suit injunction in the Commercial Court (U&M v KCM) and an injunction in the Companies’ Court to prevent the presentation of a winding-up petition. He edited the section on injunctions in Keating on Construction Contracts.

    Justin is a renowned authority on the Housing Grants Construction and Regeneration Act 1996. In 2013 he expanded the application of the Act by arguing that a collateral warranty was a “construction contract” (Parkwood v Laing O’Rourke).  In September 2014 he successfully argued that an express contractual right to adjudicate did not fall within the operation of the Contracts (Rights of Third Parties) Act 1999 (Hurley Palmer Flatt Ltd v Barclays Bank plc). 


    Justin Mort is recommended as a leading junior in in Chambers and Partners for construction (Band 1) and energy & natural resources. He is also recommended for construction in Chambers Global and the Legal 500.
