Immigration and Public Law


Trevor is a director of public law and immigration at Duncan Lewis, having joined in 2012. Over the last 15 years Trevor has garnered extensive experience in virtually every aspect of immigration law, and since 2012, he has specialised exclusively in immigration related judicial review and Court of Appeal cases.

Examples of Trevor’s successful cases, include; unlawful detention claims, challenging the legality of a refusal to grant indefinite leave to remain to an adult claimant who resided in this country for over seven years as a child prior to the expiry of the Home Office police DP5/96, challenging the legality of the Secretary of State’s refusal to exempt an individual from the knowledge of life in the UK test, and challenging the refusal to grant leave to remain to an elderly stroke victim cared for in this country by her British children and grandchildren since 2003.

Trevor’s extensive experience in the Court of Appeal includes acting in the 2016 case, SB and ABD (A Minor), R (On the Application Of) v SSHD, which established the precise circumstances in which a claimant can qualify for further discretionary leave to remain. He also acted in an extremely important human rights case, which held that it is still possible to succeed on a human rights claim under Article 8 of the European Convention of Human Rights, even after the refusal of an Article 3 claim, in MM (Zimbabwe) v SSHD.  

In the Supreme Court case, N (FC) v SSHD, Trevor helped establish the threshold which must be reached for a claimant to be successful on an application for leave to remain made exclusively on medical grounds under Article 3 of the European Convention of Human Rights.


Trevor was admitted as a solicitor in 2001 and joined Duncan Lewis in 2012 as a partner-level director.


Trevor is a Law Society Immigration (Level 3) Advanced accredited member, which means that he has shown a high level of knowledge and experience in the area of Immigration law. There are only a small number of immigration practitioners throughout England & Wales that hold this quality mark.


Trevor gained his Bachelor of Laws (Hons) degree from the University of Warwick in 1996 and obtained his LPC from the London Guildhall University.
