Richard Padley, acting on behalf of the Architect's Registration Board ('ARB'), prosecuted John Priestley of three offences of carrying on business as an architect without registering with the ARB. Mr Priestley was brought to the attention of the ARB when he was successfully appointed as expert to the Grenfell Tower Enquiry as an architect expert witness to comment on the quality of the workmanship and selection of materials used to build the tower. When it became known he wasn't in fact registered with the ARB he lost his appointment. Mr Priestley was fined £1000 for each of three offences of carrying on business as an architect without the appropriate registration between June and August 2018. He was also required to pay the prosecution's costs in full.
