Martin McCarthy KC High Court Success in Crime Costs Appeal – R v Mpanzu [2025] EWHC 1582 (SCCO)
Chambers are pleased to share that Martin McCarthy KC has succeeded in a significant High Court crime costs appeal on behalf of a Litigator, clarifying the approach to ‘upscaling’ electronic PPE.
In R v Mpanzu, Senior Costs Judge Rowley held that: When billing data is provided in raw PDF format, all information printed on the page should be treated as potentially relevant, unless shown otherwise.
For data produced in A1 format, the correct multiplier is x8, not x4—marking a key shift in how electronic evidence is assessed.
This judgment provides welcome clarity for litigators navigating complex digital evidence and reinforces a fairer, more consistent approach to costs assessment.
