The Supreme Court overturned a 40-year-old rule by allowing children to claim damages for lost years of life due to medical negligence, prompted by an 11-year-old girl (identified as CCC) who sued Sheffield Teaching Hospitals NHS Foundation Trust over injuries from negligent care.

In a 4-1 decision, the Court sent the case back to the High Court to calculate lost years damages, rejecting the 1981 rule that barred such claims for children without dependants and holding that compensation should rely on available evidence of impact rather than age-based assumptions.

The ruling overrules the 1981 Croke v Wiseman decision and brings the damages framework for minors in line with broader principles on compensation for harm.

Stakeholders acknowledged higher potential costs but stressed redressing historic injustices and preventing future harm, noting the ruling underscores the NHS’s ongoing exposure to clinical negligence costs.

Lord Reed said an age-based line is inconsistent with principle, and the assessment should use whatever material is reasonably available to determine just compensation.

The High Court will consider the family’s bid for about £800,000 in additional damages to reflect lost earnings and pension losses from ages 29 to 85, based on UK averages.

Dissenting voice: Lady Rose warned that calculating lost years for children may be problematic if evidence of earning capacity or personal circumstances is insufficient, highlighting ongoing debate about scope.

The ruling emphasizes proportionality in damages — losses should be compensated to reflect the actual harm rather than enforcing a rigid age threshold.

The decision is expected to raise the NHS’s future costs in medical negligence settlements by allowing compensation for long-term lost earnings and future care in childbirth-related negligence cases.

CCC’s mother expressed relief, viewing the ruling as correcting a historic injustice and aiding other injured children, with lawyers calling it a fair acknowledgment of the impact of life-shortening negligence.

This case signals a shift in how minors’ damages are calculated in UK medical negligence, potentially shaping future litigation and compensation practices for affected children.

Initial estimates had around £823,506 for lost years, with CCC’s team arguing for roughly £9.2 million total; the final figure will be determined by the High Court after the ruling.
