At 4 New Square, which is notably strong in handling work from the accountancy, financial, legal, and actuarial professions, Jamie Smith QC represented Deloitte in a high-profile judicial review concerning R (Lewin) v FRC and issues around the practice of ‘Maxwellisation’, which concerned whether third parties impacted by regulatory decisions can be permitted to respond to adverse comments about them prior publication, thereby limiting potential reputational damage. Before the Institute of Chartered Accountants in England and Wales, Scott Allen successfully defended an accountant accused of dishonesty. The case raised important issues about the way in which dishonesty must be alleged and proven before disciplinary tribunals.
