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.

Areas of Expertise:

"In the landmark case of Hoop v. Doe,  the Chief Judge of the US District Court for the Southern District of Iowa approved alternate service of process on the defendants' wallet address using an NFT. The Court found that service provided in this manner was "reasonably calculated to reach" the defendants since all other methods of providing service were inadequate. This resulted in the Court entering a permanent injunction against disposition of the assets at issue, freezing them at the exchange level and preventing them from being disposed of on any exchange that performs KYC on its customers. It is my hope that many more such cases will be brought, and justice will become more prevalent on the blockchain." - J. Mason Bump
