Michael is a senior and distinguished Queen’s Counsel, whose career has included practising at the Common and Commercial Law Bar, as a Senior Legal Adviser with HM Customs& Excise and, subsequently, as a tax partner in international law and accounting firms. He was called to the Bar in 1974, admitted as a Solicitor in 1991 and, having returned to the Revenue Bar in 1997, was appointed Queen’s Counsel in 2002. He was Head of Indirect Tax at Hogan Lovells International LLP from 2012 until he returned to Chambers to practise in 2015.

For much of his career, Michael has specialised in indirect taxes with a particular focus on European Union law, acting for a wide range of clients in the banking, financial, insurance, real estate and retail sectors. He is an experienced tax litigator and has appeared as an advocate before all UK courts and tribunals and at the European Court of Justice. He represented the motor dealer claimants in the compound interest Group Litigation and Loyalty Management in its successful appeal to the Supreme Court relating to the Nectar Card scheme. He regularly advises charities in the arts and educational sectors (of which he is a particular supporter) and high net worth individuals with indirect tax issues.

As well as acting for many of the global players, Michael also enjoys taking cases from small businesses/professional firms, which often raise interesting or novel points of law or practice.  

He has advised on professional negligence claims relating to tax, acted as an expert witness and sat as an arbitrator.

He is a frequent conference speaker and panel chairman.
