Mark specialises in media, public and human rights law.
He has acted in numerous leading media, human rights, and public law cases over the last 25 years. Clients have ranged from the Leader of the Opposition to survivors and bereaved in the Grenfell Tower Inquiry. He has developed and acted in strategic litigation in the UK (e.g. winning the right to settle in the UK for thousands of Gurkha veterans) and in Europe (e.g. securing human rights protection for thousands of asylum seekers subject to inter-state transfers under the Dublin regime).
He is instructed as lead counsel against silks in both domestic and international courts. International cases include the landmark European Court of Justice case of McCarthy, in which he defeated the UK’s claim to a unilateral right to suspend free movement rights. He was lead counsel throughout, ultimately appearing against the Attorney General, who told the Grand Chamber that “the issues are of exceptional importance from the perspective of the UK”.
