A significant costs judgment is set to reshape how medical evidence is funded in personal injury and clinical negligence litigation.

In JXX v Archibald, Senior Costs Judge Rowley departed from the two-decade-old Stringer v Copley authority, ruling that Medical Reporting Organisation (MRO) fees should be treated as disbursements rather than outsourced solicitor work — and capping recoverable mark-up on expert fees at 25%, well below the 30–53% typically charged.

As Bond Solon notes, the ruling marks “a significant shift in how Medical Reporting Organisation (MRO) fees are treated in costs recovery,” with the court unpersuaded that market competition or MRO business realities justified higher mark-ups.
The decision is being appealed by both parties — Premex’s appeal targets the 25% cap specifically — but in the interim it is expected to carry, in the words of costs barrister Nicola Shaldon (4 New Square), “significant persuasive weight given the seniority of the costs judge.”
