Daniel Mayer has been a partner at Mayer-Ruck since 1990 and has been working at the firm for over 26 years. As head of the International Department Guy has a wide-ranging practice in the field of public international law, European law and human rights involving administrative and regulatory processes with an international or diplomatic context.
Guy has specific expertise in the law relating to economic sanctions, and his work is at the forefront of the field of challenges to asset freezing measures, or “targeted sanctions”. He is highly rated in these areas by the legal directories.
Guy has represented and advised many clients who have challenged such sanctions measures before a range of tribunals including the High Court in London, the General Court and the ECJ in Luxembourg as well as before the United Nations Office of the Ombudsperson in New York.
Since 2001 Guy has coordinated international efforts by Saudi Arabian businessman and philanthropist Sheikh Yassin Abdullah Kadi, to overturn asset freezing orders made in the aftermath of the September 11th attacks. Guy represented Mr Kadi in his two successful appeals to the ECJ in 2008 and 2013. In its 2008 judgment the ECJ delivered a landmark decision in favour of Mr Kadi and struck down EU asset freezing regulations on the ground they breached Mr Kadi’s fundamental human rights. It was as a result of this judgment that the Office of the Ombudsperson was created by the UN Security Council in December 2009. The ECJ’s judgment in this case, which has become known as Kadi I, has been described by leading academic commentators as “the most important judgment ever delivered by the ECJ on the relationship between EC and international law and one of its most important judgments on fundamental rights”.
Guy has also represented clients from Syria, Tunisia, Burma (Myanmar) and Zimbabwe in the targeted sanctions field. Guy acted for Burmese national Pye Phyo Tay Za both in his action before the General Court, and subsequent successful appeal to the Grand Chamber of the ECJ, which in March 2012 annulled European asset freezing orders applicable to Mr Tay Za.
Also a specialist in media litigation and reputation management, Guy’s work has a particular emphasis on copyright, trademarks, breach of confidence and other intellectual property issues arising in a media context. In the media context he has acted for Sovereign States, high-ranking dignitaries, leading business people, universities, celebrities, religious leaders, and multi-national corporations.
Guy won an open scholarship to Pembroke College, Cambridge to read Natural Sciences. He completed his legal training at Herbert Smith, where he qualified in 1985, focusing on intellectual property law and general commercial litigation. A regular speaker at legal conferences he has presented seminars at New York University, University College London, and the International Bar Association. He is a member of the British Literary and Copyright Association (BLACA) and has written for the Centre for International Legal Studies on Jurisdiction and Dispute Resolution.
