Robert was called to the Bar in 1996 and is a member of Gray’s Inn.


  • Chancery
  • Commercial
  • Employment
  • Holiday and Travel Law 
  • Personal Injury
  • Tax


Before practicing at the Bar, Robert worked for several years as an institutional fund manager for a major UK insurance company with several billion pounds under management. The intricate understanding and knowledge he has gained of financial markets, company accounts and market regulation gives him an unrivalled background for two of his areas of practice in particular, namely tax and commercial. He regularly appears in court at all levels.

He is a chartered fellow of the Chartered Institute for Securities and Investment (for which he is an external specialist adviser) and a member of the Revenue Bar Association. 

He has recently had an appeal against HMRC successfully determined under TMA 1970 s54 and successfully represented a company in the High Court to rescind its winding - up order. 


He is routinely instructed on a variety of trust (and Will) matters including the interpretation and drafting of trusts. He has a particular interest in the meaning and consequence of “shams”.  

He has regularly advised on, and appeared (successfully!) in insolvency cases, often both for and against HMRC. 


He undertakes a wide variety of commercial cases and has often acted both for and against the clearing banks; at present he has a particular interest in the alleged mis-selling of their derivative products.

Employment Law

Robert has a growing interest in this area. Having worked for many years in the City, he has a natural affinity with investment bank employees whom he often represents. 

Personal Injury

He has had much experience in this area over his years at the Bar; coming from a medical family, this is perhaps unsurprising. He regularly advises on quantum for PI claims.


Robert covers all the direct taxes and regularly advises and represents private clients, trustees and SMEs. His work ranges from advising private clients and trusts on CGT to advising companies on share schemes and advice on the merger of trusts.   

Other civil

Robert regularly appears in court on a variety of other civil matters including negligence (a speciality being Road Traffic Accidents and related credit hire claims) and Travel cases. From his early days at the Bar, he has vast experience of possession actions, charging orders and the like. 

Robert is accredited under the Public Access Scheme to accept direct instructions.
