This guide provides general educational information. It does not replace legal advice, regulatory guidance or a case-specific assessment.
Authority before access
Authority before access should be examined in relation to the specific objective of digital forensics explained: preservation, examination and limits. The enquiry should use relevant, authorised sources, distinguish verified facts from indicators, and explain where information is incomplete, conflicting or unavailable. Decisions should not rely on a single isolated record when context or corroboration is required.
A proportionate approach records source quality, date, context and practical limitations. Where the matter may affect legal, employment, regulatory, clinical or financial decisions, qualified advisers should interpret the findings within their professional role.
