Alan Maclean KC is an accomplished and experienced Silk.  

He is equally at home in first instance trials in the Commercial Court, the Chancery Division, international arbitration or the CAT, requiring detailed mastery of complex facts, as he is arguing points of law in the Supreme Court, the Court of Appeal or the Administrative Court.  He strives always to demonstrate mastery of the essential skills of a 21st century Silk: a firm grasp of legal principle; sound judgment; enthusiasm for hard work; strategic and tactical awareness; skilful cross-examination of lay and expert witnesses and excellent written and oral advocacy.  

Alan has built a broad practice in Silk, ranging across many aspects of commercial litigation and arbitration (in such fields as civil fraud, energy, sanctions, telecommunications and sports law) as well as public and regulatory law.   Competition law, in the Court of Appeal, the High Court, the CAT and the CMA has also become an important part of Alan's busy practice.

Alan's practice also includes a significant advisory element.  He endeavours to provide straightforward, dispassionate and realistic advice, whether in writing or in consultation. 

In addition to his work in England and Wales, Alan has appeared as leading Counsel in Gibraltar, the BVI and before both the Cayman Island and Eastern Caribbean Courts of Appeal. He has also advised in several Hong Kong matters and has experience as an arbitrator.

Alan has long been recognised as a leading Silk in the leading legal directories, Chambers UK and the Legal 500. In the latest editions he is variously recommended for his expertise across administrative and public law, commercial litigation, energy, international arbitration and professional discipline/regulatory work.
