An entrepreneur pursuing judicial review proceedings (Public Access client)
“Mark was meticulous down to the last detail. He was understanding and took a real interest in our case and I feel sure we wouldn’t have had the same positive outcome had we had a different barrister. Mark, along with his paralegal Eva, ensured a very smooth and efficient experience, putting together our evidence in a very professional and diligent manner and very promptly answering our many questions. I can highly recommend Mark as being a very reliable and knowledgeable barrister.”

Mark sits as a judge of the Upper Tribunal and First-tier Tribunal which gives him great insight into the way a case should be presented. He has particular expertise in higher appeals having spent many years specialising in test-case litigation both with the Refugee Legal Centre and since arriving in private practice; he is very well known to the Senior Immigration Judiciary at Field House – see for example the Foreword to his new book with Peter Jorro Immigration Appeals and Remedies Handbook (“invaluable … to the armoury of all … a compulsory addition to the library of every immigration judge and practitioner”: President of the Upper Tribunal Mr Justice McCloskey). Mark is very active in public speaking and training (he is a Fellow of the Institute of Advanced Legal Studies with “encyclopaedic… pre-eminent” knowledge according to one Supreme Court judge) and is a contributor to MacDonald’s Immigration Law and Practice. Mark has long been one of the experts who specialist immigration lawyers go to in order to make sure that they are up to speed with the latest legal arguments.
Business and private immigration
Mark’s business acumen, developed whilst being a company director at HJT Training (which he established and expanded with fellow Garden Court Immigration Team member David Jones), makes him a good choice for commercial immigration advice. He has real expertise in every aspect of business immigration, from Van Der Elst visas to investors, entrepreneurs and Tier 2 inter-company transfers. He has advised numerous wealthy individuals in complex cases involving different aspects of immigration law. He has particular expertise with remedies against difficulties that have arisen under the Points Based System including the withdrawal and suspension of sponsor licences, both of employers and educational establishments, an area on which he has written and spoken extensively. Mark has repeatedly been chosen as the Immigration Lawyers’ Practitioners’ Association speaker of choice at their annual conference for expert business immigration lawyers.
European Union free movement law
Mark has particular expertise in all aspects of European Union free movement law from claims under the 2006 Regulations to free-standing applications relying directly on Treaty Rights. He regularly trains and speaks publicly on matters involving European Economic Area (EEA) nationals. His successful judicial review case of Heritage (IJR)  UKUT 441 on the relationship between EU residence rights and “precarious” immigration status has received significant attention: the government has now been granted permission to appeal to the Court of Appeal.
Public and administrative law
Mark has a flourishing judicial review practice, specialising in human rights, refugee, and subsidiary protection issues, though frequently extending to all kinds of public law challenges to the Home Office decision making. He has been at the forefront of litigating “no right of appeal” judicial reviews on human rights grounds, a topic on which he has written and spoken extensively.
Refugee and asylum law
Recognised by the legal directories as a “real expert on asylum matters”, Mark is co-author (with Peter Jorro, also of Garden Court) of Asylum Law and Practice described as and as “indispensable in advocacy work for refugees and human rights”, by Professor Guy Goodwin-Gill. He is particularly interested in the European dimension of international protection, and arguments based on the Qualification, Procedures and Reception Directives, and the Charter of Fundamental Rights. Mark’s interests and experience extend to issues of exclusion from refugee status and subsidiary protection. He is a member of UNHCR’s pro bono panel of advocates and is a convenor for the International Association of Refugee Law Judges. He is also a Visiting Fellow at the Refugee Law Initiative, School of Advanced Study, at the University of London.
Mark conducts compliance and regulatory work, and has worked for the Law Society, Office for the Immigration Services Commissioner, and with individual law firms in contractual disputes with the Legal Services Commission (LSC, now the LAA). His previous experience as a solicitor working under public funding is especially useful in this regard.

Mark appeared for the claimants in the earlier test case on the safety of Italy for “third country” returnees.
Mark has been extensively involved in a number of challenges to returns to Greece, in which context he has repeatedly addressed conferences of Europe’s leading asylum lawyers.

SQ (Pakistan) & Anor  EWCA Civ 1251

Mark was instructed by Mark Lilley-Tams of Paragon Law.
