Dr. Stephen Castell, Chartered Information Systems Practitioner and Member of the Expert Witness Institute, is Chairman of CASTELL Consulting. He is an internationally acknowledged Independent Computer Expert who has been involved in a wide range of computer litigation over many years. CASTELL Consulting, currently in its twenty-fifth year, provides independent professional consultancy and expert services in Computer Systems, Software, Project Management, Strategy, and Contract Disputes, to a wide variety of international clients and companies. 

As an Expert Witness in computer litigation, Dr. Castell has acted in over 100 major cases including the largest and longest computer software actions to have come to trial in the English High Court. He is the author of the best-selling Computer Bluff (1983), and of The APPEAL Report (1990) on the admissibility of computer evidence in court and the 'legal reliability' of information systems and technologies (with the CCTA).

Dr Castell, award-winning international Professional ICT Consultant and Expert has acted as expert witness in an unusual medical equipment procurement litigation of relevance to the current Covid-19 pandemic and its profound clinical and hospitalisation implications.  The court case, specific details of which cannot be given since the matter is subject to Confidentiality Hearing strictures, was over a dispute concerning due and diligent process undertaken by a major Hospital Management Group, the Defendant in the action, in issuing a Tender for complex diagnostic units, and the Group’s selection of the bid put in by a US corporation, a leader in its field.  That winning bid was challenged by a Claimant, another US corporation, a market competitor to the winning company.  The dispute hinged on whether or not the operational computer software of the winning bidder’s units was compliant with the Hospital Management Group’s strict Tender stipulation that the software had to be identical across all versions of the equipment to be supplied in meeting the Tender requirements.  

Dr Castell’s investigation and analysis of the operational software involved, and his opinion as to the extent that the software was compliant with the strict Tender condition, provided insight and assistance to the parties in reaching a satisfactory settlement.
