1981-1998: As a junior specialising in company/commercial litigation, Jonathan was heavily involved in cases such as Guinness, Polly Peck and Barlow Clowes, as well as numerous shareholder disputes, and media and entertainment cases.  He also appeared overseas, in the Sea Containers takeover dispute and in the litigation following the insolvency of Bermuda Fire and Marine.  Chambers & Partners described him as an "absolute star", and ranked him in 4 categories - company law, financial services, chancery and insolvency.  The Legal 500 described him as "brilliant" and "outstanding", ranking him as one of the top 3 juniors at the Bar, with recommendations in commercial litigation, company law, banking and insolvency.

1998-2006: In 1998 Jonathan was appointed First Treasury Counsel (Chancery), and for the next 8 years he was retained exclusively by the Government.  His practice widened to include all aspects of public law, with an emphasis on human rights and freedom of information.  Although by convention he remained a junior, his practice was effectively that of a silk throughout.

2006 onwards:
In 2006, Jonathan returned to private practice as a silk.  On announcing his retirement as First Treasury Counsel, the Attorney General said that Jonathan was a barrister "of the very highest calibre" who had given "outstanding service to the government in many cases of the greatest public importance".  Jonathan now combines his wider experience in public law with his previous specialisation in company/commercial litigation.  He has been named as Lawyer of the Week in The Times, as one of the Hot 100 by the Legal 500 and as Chancery Silk of the Year by Chambers UK.
