Dunlop v McGowans

Factual and Procedural Background

The Appellant purchased a block of property in The City in 1970 with the intention of redevelopment. A portion of the premises was leased to a cooperative society under a tenancy that could be terminated at Whitsunday in any year provided 40 days’ written notice was served. The Appellant instructed the Respondents, solicitors, to give the requisite notice so that vacant possession could be obtained at Whitsunday 1971. The Respondents failed to do so, resulting in the tenant remaining until Whitsunday 1972 and delaying the redevelopment.

On 3 November 1976—more than five years after the missed notice—the Appellant sued the Respondents for negligence and breach of contract, claiming various heads of pecuniary loss incurred both before and after 3 November 1971. The Respondents invoked quinquennial negative prescription under Part I of the Prescription and Limitation (Scotland) Act 1973.

The Lord Ordinary allowed a proof before answer, holding that prescription did not extinguish claims for losses incurred after 3 November 1971. On reclaiming motion, the Second Division recalled that interlocutor and dismissed the action. The Appellant then appealed to the House of Lords, which delivered the present judgment on 6 March 1980.

Legal Issues Presented

1. Whether, under section 11(1) of the Prescription and Limitation (Scotland) Act 1973, each separate item of pecuniary loss constitutes a distinct “appropriate date,” thereby preventing negative prescription from extinguishing claims for items suffered within five years of the action.
2. Whether section 14(1)(a) of the Act, dealing with time occurring before commencement of Part I (25 July 1976), suspends or resets the five-year prescriptive period when that period had already fully elapsed before commencement.

Arguments of the Parties

Appellant's Arguments

• Section 11(1) produces multiple “appropriate dates”: one for each provable pecuniary loss. Losses suffered after 3 November 1971 were therefore still actionable, even though earlier losses were time-barred.
• A distinction should be drawn between “pecuniary loss” (actual, quantified loss) and “potential loss” (future or unquantified loss). Only when a loss becomes pecuniary does the prescriptive clock start for that item.
• Under section 14(1)(a), because more than five years had expired by 25 July 1976, none of that pre-commencement time should count toward the quinquennial period, leaving the Appellant with a fresh five-year period from 25 July 1976.

Respondents' Arguments

• The obligation to make reparation is single and indivisible; prescription runs from the concurrence of injuria and damnum—here, Whitsunday 1971—regardless of later quantification.
• Section 11(1) merely fixes the point when loss occurs; it does not fragment the obligation into multiple enforceable dates.
• Section 14(1)(a) is a transitional provision intended only to allow up to, but less than, five years of pre-commencement time to count; it does not wipe out periods longer than five years.

Court's Reasoning and Analysis

The court characterised the Respondents’ liability as a “single and indivisible obligation” arising when the Appellant could not obtain vacant possession at Whitsunday 1971. It rejected the Appellant’s attempt to split losses into discrete items for prescription purposes, noting that section 11(1) simply clarifies that the prescriptive period starts when loss, injury, or damage is sustained—not when separate monetary consequences later materialise. Allowing multiple start dates would generate uncertainty and “confusion,” contrary to the Act’s purpose.

The court further found no textual basis in the Act for distinguishing “pecuniary” from “potential” loss. Quantification difficulties at the outset do not postpone the running of prescription; estimation would have sufficed in 1971.

Addressing section 14(1)(a), the court construed the proviso as transitional: where more than five years had already elapsed before 25 July 1976, all but four years and 364 days of that period would still count. Thus, the full quinquennial period had indisputably expired before Part I commenced, and the action was time-barred. The court regarded the Appellant’s contrary reading as producing an “absurd” result and inconsistent with legislative intent.

Holding and Implications

Appeal dismissed; the decision of the Second Division is affirmed.

The Respondents’ obligation to pay damages was extinguished under the five-year negative prescription, and the Appellant’s action cannot proceed. The judgment clarifies that section 11(1) does not permit fractional prescription dates for separate heads of loss and affirms a strict, single-obligation approach to the commencement of prescription under Scottish law. No broader precedent was announced beyond the interpretation of the 1973 Act’s relevant provisions.
