Awareness of Possible Negligent Treatment, Not Death Alone, Starts the Fatal-Claim Triennium
Case: CD and others against Grampian NHS Board
Citation: [2026] CSOH 92
Court: Outer House, Court of Session
Judge: Lord Arthurson
Date: 17 September 2026
1. Introduction
This fatal medical-negligence action arose from the death of E, a young child, in September 2019 following a brain tumour and haemorrhage. Grampian NHS Board admitted breach of duty and causation, accepting that negligent delay in appropriate care and treatment caused the death.
Claims brought by three relatives were settled extra-judicially. The remaining claims were those of E’s father, his subsequent wife, who had played a substantial role in E’s upbringing, and that wife’s adult daughter. Their claims were confined to grief and sorrow damages under section 4(3)(b) of the Damages (Scotland) Act 2011.
The court had to decide:
- when the three-year limitation period began for each claimant;
- whether equitable relief should alternatively be granted under section 19A of the Prescription and Limitation (Scotland) Act 1973;
- whether the adult daughter qualified as E’s statutory “relative”; and
- the appropriate damages for the father and stepmother.
2. Summary of the Judgment
-
The father and stepmother did not have actual or constructive awareness of the facts connecting E’s death with possible negligent treatment until they received the summons on 13 September 2022.
-
Their limitation period therefore began on that date. The procedure by which they joined the action was consequently timeous.
-
If that conclusion were wrong, the court would nevertheless have exercised its section 19A discretion to permit their claims to proceed.
-
The adult daughter did not qualify as E’s deemed sister under section 14 of the 2011 Act because she had not been brought up in the same household as E and accepted as a child of the same family.
-
Her claim was also time-barred because she gave no evidence capable of establishing her own date of knowledge. Claimants could not be treated collectively as a “family block”.
-
The father was awarded £150,000 and the stepmother £75,000, both inclusive of interest to the date of decree.
3. Factual Findings Central to Limitation
E lived with the father and stepmother during regular residential contact. The evidence established a close, loving and settled family relationship. The stepmother had been heavily involved in practical aspects of E’s upbringing, while her adult daughter also maintained a substantial bond with E.
The decisive feature was the relatives’ exclusion from information about E’s earlier treatment. They were abroad when E deteriorated, returned urgently, and encountered her at an advanced and terminal stage. Information from clinicians concentrated on diagnosis and prognosis, not on the history of delayed admission or treatment.
They were estranged from E’s mother, had no relevant communication with other relatives involved in the litigation, and knew nothing about the NHS Board’s Significant Adverse Event Review. Until the summons was sent to them, they understood E’s death as the tragic progression of a fatal brain tumour rather than as a consequence potentially attributable to negligent non-treatment.
4. Legal Reasoning
4.1 Section 18: actual and constructive awareness
Section 18 of the Prescription and Limitation (Scotland) Act 1973 makes the limitation period in a fatal claim depend not only on the date of death but also on when the claimant became, or could reasonably have become, aware of the material statutory facts. Those facts include the possible attribution of the death to an act or omission.
Lord Arthurson rejected the argument that the father and stepmother should have inferred wrongdoing merely from E’s death or from some general awareness of delay. A catastrophic outcome does not by itself establish constructive knowledge of negligence.
There must be some factual basis capable of alerting the particular claimant that the death may be attributable to another person’s act or omission. Here, no clinician explained that delayed care had affected the outcome, and the claimants had no reason to suspect substandard treatment. In those circumstances, there was also no obligation on them to make further enquiries.
Their first relevant awareness arose on 13 September 2022, when the summons disclosed that something may have gone wrong in E’s treatment. The triennium therefore started then, making their subsequent joinder to the proceedings timeous.
4.2 Knowledge must be assessed individually
The sixth claimant’s position demonstrated that limitation is personal to each pursuer. She did not give evidence, and her written statement did not address her knowledge or the reasonableness of any failure to investigate. She therefore failed to discharge the burden of bringing herself within section 18.
The court expressly rejected the proposition that all relatives could be treated as a single “family block”. One family member’s evidence or date of knowledge cannot automatically establish another’s entitlement to rely on delayed awareness.
4.3 Section 19A: equitable relief from time bar
Lord Arthurson considered section 19A as an alternative basis for allowing the father’s and stepmother’s claims. The court acknowledged two matters favouring the NHS Board: the admitted failure of the instructed solicitor to add the claimants before the asserted deadline, and the loss of the Board’s limitation defence.
Those factors were outweighed by the wider equities:
- the principal action had been raised timeously;
- the Board had already investigated the underlying events fully;
- liability had been admitted;
- three related claims had already been settled;
- the disputed delay was measured in weeks; and
- there was no material evidential prejudice caused by that short delay.
Refusing relief would therefore have given the Board a windfall rather than protected it from genuine forensic prejudice. Had section 18 not preserved the claims, section 19A would have been exercised in their favour.
4.4 Statutory eligibility of the alleged sibling
The adult daughter argued that, because her mother was E’s stepmother, she and E should be deemed sisters under section 14 of the Damages (Scotland) Act 2011.
The court adopted a plain reading of the statutory language. The claimant had to show that she had been brought up in the same household as E and had been accepted as a child of the family in which E was also a child. Regular visits and maintaining a bedroom for contact periods did not satisfy that requirement. As an adult who had been brought up in a different household, she fell outside the statutory class, despite the genuine closeness of the relationship.
The court regarded the result as unattractive but held that emotional closeness could not replace the statutory household and upbringing conditions.
5. Precedents Cited
Paterson v Lanarkshire Heath Board 2023 SLT 67
Lord Arthurson treated the award in Paterson v Lanarkshire Heath Board 2023 SLT 67 as a “barometer” for parental bereavement damages. He concluded that the death of a very young child in the present circumstances required an uplift from the figure used there.
The authority therefore operated as a comparative starting point rather than a rigid tariff. The resulting £150,000 award to the father reflects a broad, fact-sensitive assessment of grief and sorrow.
McArthur v Timberbush 2021 SLT 1021
The court referred to McArthur v Timberbush 2021 SLT 1021 when assessing the stepmother’s award at £75,000. The opinion does not set out the case’s facts or detailed reasoning, so its precise comparative role is not fully explained. Its citation indicates that the court used existing bereavement awards to calibrate the value of a close parental-type relationship that was not identical to the biological father’s position.
No limitation authorities are identified in the short ex tempore opinion. The parties’ written submissions were incorporated by reference but not reproduced.
6. Assessment of Damages
Section 4(3)(b) of the 2011 Act permits compensation for the grief and sorrow caused by a deceased person’s death. Such damages are non-patrimonial: they compensate personal suffering rather than measurable financial loss.
The court adopted a broad but relationship-sensitive approach. It considered the child’s age, the depth and quality of the relationships, the family arrangements, and the evidence of affection and involvement.

7. Complex Concepts Simplified
- Triennium
- The three-year period within which an action must ordinarily be brought.
- Constructive awareness
- Knowledge that a person does not actually have but could reasonably have acquired through appropriate enquiry.
- Section 19A discretion
- The court’s equitable power to allow an otherwise late personal-injury or fatal claim to proceed when it is fair to do so.
- Sist as an additional pursuer
- In this context, the procedure for joining a person to an existing action as another claimant.
- Loss of society damages
- Compensation payable to qualifying relatives for non-financial consequences of a death, including grief, sorrow and loss of the deceased’s society.
8. Potential Impact
The decision is a fact-sensitive Outer House authority rather than an appellate reformulation of section 18. Nevertheless, it provides important guidance in fatal medical-negligence litigation:
- A death or grave medical outcome does not automatically put relatives on notice of negligence.
- Constructive knowledge requires a reason to suspect that treatment or non-treatment contributed to the death.
- Family estrangement, exclusion from clinical information and ignorance of internal investigations may materially postpone the date of awareness.
- Each claimant must establish their own knowledge position; relatives cannot rely automatically on evidence given by other family members.
- Section 19A relief is more likely where the defender already investigated a timely principal action and suffers no practical prejudice from a short delay.
- Close emotional relationships do not expand the statutory categories of relatives beyond the language chosen by Parliament.
- The awards may provide a significant reference point for future Scottish claims involving the death of a young child and parental or parental-type grief.
9. Conclusion
CD and others against Grampian NHS Board confirms that the fatal-claim limitation period does not begin merely because relatives know of a death or an unsuccessful medical outcome. Where they have no information suggesting negligent treatment and no reasonable basis for enquiry, time begins only when they first become aware of the possible connection between the death and an act or omission.
The judgment also stresses the individual nature of limitation, the importance of actual forensic prejudice under section 19A, and the strict statutory limits on who may claim as a relative. Its substantial damages awards recognise both the exceptional gravity of losing a young child and the need to assess each relationship on its own evidence.
