1 Chancery Lane has long had a reputation for appellate advocacy at the highest level.

Last week Andrew Warnock Q.C. and Maurice Rifat were successful in the Supreme Court in the case of Stoffel & Co v Grondona [2020] UKSC 42 which concerned the impact of the illegality defence to a claim against a solicitor for professional  negligence in the context of a mortgage fraud.

The application of the illegality defence was also considered this year by the Supreme Court in Whittington Hospital NHS Trust v XX [2020] UKSC 14 in which Lord Edward Faulks Q.C. appeared for the appellant.

The issue of the “illegality” defence occurs in all Chamber’s practice areas and to mark Andrew’s and Maurice’s success in Stoffel we are offering our clients this bumper bulletin on this sometimes tricky issue.

• Maurice Rifat offers an overview of the development of the illegality defence and the role it plays in our legal system. Read Maurice Rifat’s article here.

• Andrew Spencer explains how the Supreme Court dealt with illegality as a defence to a professional negligence claim in Stoffel and looks for clues as to when the illegality defence might succeed in a professional negligence case.  Read Andrew Spencer’s article here.

• Zachary Bredemear looks at Stoffel from a property law perspective and offers three lessons to be taken from the case. Read Zachary Bredemear’s article here.

• Laura Johnson considers how the Supreme Court dealt with the illegality defence when confronted by issues of mental health and manslaughter in Henderson v Dorset Healthcare University NHS Foundation Trust (which was handed down with Stoffel) and explains how Whittington fits into the courts’ approach to illegality in medical negligence claims.  Read Laura Johnson’s article here.
