This book examines the role of immigration lawyers who represent victims of trafficking and explores modern slavery frameworks within the constraints of the legal aid market. Underpinned by cause lawyering theories, it exposes the real-life professional and personal impact of being an immigration lawyer representing victims of trafficking. It explains strategies used by lawyers to achieve good legal outcomes for their clients, but also the ways they seek to shape the law itself and their motivations for doing so. The book explores the ways in which modern slavery, regarded as a heinous crime with serious, long-term consequences for victims, is high on the political agenda and has been a focus of government action in recent years. It argues that because many victims of trafficking do not have a right to remain in the UK, leading to a dangerous lack of support, access to an immigration lawyer can be their only path to stability. Interviews with immigration lawyers who represent victims of trafficking are drawn on throughout this book, alongside analysis of complex legal cases and frameworks. At a time when called 'do gooder' lawyers have themselves been under the spotlight, this book goes behind the headlines to examine the role of immigration lawyers who advise and represent victims of trafficking, navigating immigration law and modern slavery frameworks within the constraints of a legal aid market ill-fitted to the complex cases of their clients.
