What makes defence disputes distinct
Defence matters sit at the meeting point of complex engineering and demanding contracting, under security constraints that few other sectors share. A dispute might concern a procurement contract's performance, the integration of a complex system, a programme's cost and schedule, or export-control compliance. The right expert understands both the technology and the contracting environment, and is mindful of the classification and confidentiality issues that come with the territory.
Procurement, systems and programme delay
Procurement disputes turn on contract performance, requirement definition and acceptance under demanding frameworks. Systems engineering questions ask whether the engineering met the specification and intended capability. Programme delay and quantum claims, common in long defence programmes, require structured delay analysis and a clear account of what drove cost growth, disruption and acceleration. The Ministry of Defence and its delivery bodies set the contracting context.
Export control, cyber and supply assurance
Export control matters require familiarity with licensing regimes and controlled-goods classification, administered in the UK by the Export Control Joint Unit. Cyber and information security in defence systems is increasingly litigated, and manufacturing and supply assurance disputes test quality systems, non-conformance and the provenance of parts.
Instructing within the constraints
Defence instructions need an expert who can work within security and confidentiality requirements without compromising independence. That independence, the overriding duty to the court under CPR Part 35, is exactly what gives the evidence weight. Our guide on how to instruct an expert witness explains the process.
