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.
In a recent trial, in which I acted as an expert witness, some notable differences appeared to me to emerge, as between UK and USA judicial standards and practices, in regard to the role, obligations, testimony, presentation and rigor of digital forensics expert findings.

Software implementation contracts are frequently terminated with the software rejected amidst allegations from both supplier and customer, e.g. software/database errors/deficiencies, faulty design, shifting user/business requirements. An important technical issue on which the IT Expert appointed in such disputes is asked to give an expert opinion is: what was the quality of the delivered software and was it fit for purpose?
Disputes over failed software construction projects raise interlinked technical and legal issues which are complex, costly, and time-consuming to unravel – whatever the financial size of the claims and counterclaims, the facts and circumstances of the contract between the parties, or the conduct of the software development

The findings of this expert investigation were clearly reported by Dr Castell to the court and (most unusually) were fully accepted by the Prosecution without any need for cross-examination, assisting in achieving a Not Guilty verdict from the Jury.

For years, this has been the definitive and comprehensive technical reference for software engineers, systems programmers, and any engineer who needs to understand Windows NT systems internals. While this text has a fresh new look on the outside, the text, pictures, code samples and references on the inside are vintage 1998. Nevertheless, the book retains a tremendous amount of value in its clear (erudite even) descriptions of the Windows NT operating system architecture and internals; information on the implementation of standard Windows NT kernel mode drivers; Key details on the workings of Windows NT I/O Manager; and detailed technical discussions on interrupt management and synchronization issues.
