CHALMERS AND (SECOND) GAIL CHALMERS AGAINST DIAGEO SCOTLAND LTD

Factual and Procedural Background

The Plaintiff couple reside in a house within a development located adjacent to and generally downwind from a whisky aging facility owned and operated by the Defendant company. The Defendant's whisky maturation process releases ethanol vapour ("the angels' share") into the atmosphere. The Plaintiffs claim that this ethanol vapour constitutes a nuisance causing damage to their property, specifically by depositing black fungus on their house and outdoor items, resulting in loss and diminution of property value. The Plaintiffs seek damages amounting to £40,000.

The case previously underwent a procedural debate before a Judge, where the Defendant sought dismissal on grounds including failure to aver a relevant nuisance claim and prescription of any cause of action. The Judge ruled that enquiry was necessary before deciding these matters and allowed the Plaintiffs to amend their pleadings to specify their claims on loss. Despite amendments, the Defendant remained dissatisfied with the pleadings' relevancy and specification regarding quantum, leading to a further procedural debate.

Legal Issues Presented

1. Whether the Plaintiffs have pled a relevant and sufficiently specific case of nuisance caused by the Defendant's ethanol vapour emissions.
2. Whether the Plaintiffs' claims for diminution in property value and cleaning costs amount to impermissible double counting.
3. Whether the Plaintiffs have provided adequate specification and fair notice of the quantification of their damages claim.
4. How to properly measure damages in relation to loss of amenity, diminution in value, and consequential losses in the context of a continuing nuisance.

Arguments of the Parties

Defendant's Arguments

• The Defendant contended that the Plaintiffs failed to state a relevant and sufficiently specific claim regarding quantification of loss and damage.
• They argued that claiming both diminution in property value and cleaning costs constitutes double counting; if cleaning costs are compensated, diminution in value should not also be claimed, and vice versa.
• The Defendant asserted that the Plaintiffs did not specify how long they intended to remain in the property, which is necessary to assess future loss and the appropriate multiplier for damages.
• They highlighted inconsistencies and lack of coherent calculation in the pleadings concerning the claimed sum, particularly regarding past and future costs.
• The Defendant maintained that the blackening was indistinguishable from common blackening in other locations, causing no material damage or diminution in property value.

Plaintiffs' Arguments

• The Plaintiffs submitted that their averments on quantification were relevant and sufficiently specific to proceed to proof.
• They argued the Defendant's double counting point was flawed because cleaning costs and diminution in value represent distinct heads of loss; cleaning costs are consequential losses separate from diminution in property value.
• The Plaintiffs asserted that there was no claim for loss of amenity and diminution in value simultaneously without adjustment, but either could be claimed along with cleaning costs and replacement of damaged furniture.
• They proposed that the multiplier for future loss should initially be actuarially based on life expectancy, subject to adjustment for any future sale of the property.
• The Plaintiffs contended that their pleadings provided fair notice of the types and amounts of expenses claimed and that precise calculation of the sum sued for would be determined after evidence is led at proof.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
Hunter v Canary Wharf Ltd [1997] AC 655	Damages for nuisance include diminution in property value and loss of amenity; personal distress is part of loss of amenity and cannot be separately compensated.	The court relied on Lord Hoffmann’s speech to explain the relationship between diminution in value and loss of amenity and to clarify that damages can be awarded for consequential losses but not double recovery for distress.
Raymond v Young [2015] HLR 805	Damages for diminution in value and loss of amenity are alternative measures; awarding both constitutes double counting.	The court used this precedent to assess the interaction between the heads of damage claimed and to conclude that the proper measure of loss should be determined after evidence, avoiding double recovery.
Bone v Seale [1975] 1 WLR 797	Illustrates the principle that diminution in capital value is not the sole measure of loss in nuisance cases involving smells.	Referenced to support the proposition that loss of amenity and consequential damages may be appropriate in nuisance cases.
Ruxley Electronics and Construction Ltd v Forsyth [1996] AC 344	Law of damages is flexible enough to award compensation for intangible losses such as loss of amenity.	Used to underpin the court's approach to valuing intangible losses linked to nuisance.
Dennis v Ministry of Defence [2003] EGLR 121	Discusses reduction of loss of capital value to account for transitory nuisance.	Referenced in the context of avoiding double recovery where diminution in value reflects historic nuisance effects.

Court's Reasoning and Analysis

The court considered the Plaintiffs’ claim of nuisance caused by ethanol vapour depositing black fungus on their property, resulting in damage and loss of amenity. The court acknowledged the procedural history, including prior rulings permitting enquiry into the merits and allowing amendments to pleadings to specify quantum of loss.

Addressing the Defendant’s contention of double counting, the court distinguished between diminution in property value (including loss of amenity) and cleaning costs as separate heads of loss. It held that cleaning costs represent consequential losses analogous to other recoverable consequential damages and are not duplicative of diminution in value, provided future cleaning costs are limited to the Plaintiffs’ period of ownership.

The court examined leading authorities, notably Hunter v Canary Wharf Ltd and Raymond v Young, to clarify that damages for loss of amenity and diminution in value are alternative measures and cannot be claimed simultaneously without adjustment. However, the court recognized that loss of amenity includes personal distress and inconvenience and that the proper measure of damages should be determined after evidence is led.

Regarding the quantification of damages, the court found the Plaintiffs’ pleadings sufficiently specific to afford fair notice of the types and amounts of costs claimed. It emphasized that in ordinary actions, detailed valuation is not required at the pleading stage and that precise assessment would follow proof. The court noted that the Plaintiffs did not aver intention to sell the property imminently, and thus an actuarial multiplier for future loss based on life expectancy was appropriate, subject to adjustment if a sale occurred.

Overall, the court concluded that the issues concerning double counting and quantum were better resolved after full enquiry and evidence, and that the Plaintiffs had pled a relevant and adequately specific case to proceed to proof.

Holding and Implications

The court's final decision was to allow proof before answer, thereby permitting the case to proceed to a full evidential hearing on liability and quantum. Questions of expenses were reserved for later determination.

The direct effect of this decision is that the Plaintiffs’ claim is not dismissed at this stage, and they are entitled to pursue their case on the merits. The ruling clarifies the approach to pleading and preliminary assessment of damages claims in nuisance cases involving ongoing environmental effects, but it does not establish new legal precedent beyond applying existing authorities.
