Anonymized and Structured Summary of the Opinion (Outer House, Court of Session)

Court: Outer House, Court of Session  |  Neutral citation: [2025] CSOH 93  |  Case reference: GP10/23

Opinion delivered by: Judge [Sandison]

Representative party: Plaintiff (represented by Attorneys [Smith], [Middleton], [Reid], [Black]; firm referenced in the opinion)

Defendants: Company A; Company B; Company C; Company D; Company E; Company F (represented by Attorneys [Ellis], [Young], [McAndrew]; firms referenced in the opinion)

Factual and Procedural Background

These are group proceedings in which the Plaintiff acts as representative party for a class of persons (about 20,600 as at a stated date in the pleadings) who claim loss and damage arising from the alleged presence in certain diesel engines of prohibited "defeat devices" within the meaning of EU Regulation No. 715/2007 (the "Emissions Regulations"). The Plaintiff seeks declarator that particular branded vehicles incorporating Euro 5 and Euro 6 diesel engines contained prohibited defeat devices that operated to reduce the effectiveness of NOx emissions control systems during normal operation while permitting compliance during test cycles, and (secondly) monetary payment to compensate group members for loss.

The Plaintiff (a retired deputy head teacher resident in the jurisdiction, described in the opinion as the representative party) asserts a personal claim in respect of a diesel vehicle acquired under a conditional sale agreement governed by the Consumer Credit Act 1974. The putative defendants are alleged variously to have been involved in designing, manufacturing, marketing, supplying, financing and retailing the affected vehicles. The summons sets out multiple bases of action, including unlawful means conspiracy, fraudulent misrepresentation, negligence, breach of statutory duty under EU and domestic regulations, breach of contract (in respect of financed vehicles), consumer-protection claims and remedies under the Consumer Credit Act.

A document recovery process had been ordered and was ongoing; this opinion arose from debate on a number of preliminary pleas (including pleas as to limitation/prescription, relevancy and specification of averments, jurisdictional questions under the Consumer Credit Act and the competency of pleaded causes such as unlawful means conspiracy and fraud). The opinion cross-references an earlier opinion of the court dealing with related procedural steps.

Legal Issues Presented

1. Whether the court has jurisdiction to entertain remedies under section 140B of the Consumer Credit Act 1974 in the context of these group proceedings (and, if so, under which subsection(s) of section 140B).
2. Whether pleaded causes of action (fraudulent misrepresentation, unlawful means conspiracy, negligent misrepresentation, breach of statutory duty, breach of contract and Consumer Protection claims) are specified with sufficient particularity and are relevant so as to survive preliminary debate and be remitted to proof before answer.
3. Whether and to what extent a substantial part of the group members' claims are prescribed (time‑barred) under the Prescription and Limitation (Scotland) Act 1973 as it stood before or after amendment, including the application of sections 6, 11, and associated rules (and the interpretation and application of the "reasonable diligence" proviso and the saving provisions for fraud/error).
4. Whether the pleaded unlawful means conspiracy case is a permissible further or new ground such that it is time‑barred because it was introduced later in the pleadings, or whether it can be treated as an elaboration of prior pleaded misconduct.
5. Whether any pleaded alternative or apparently inconsistent averments (for example, that there were no defeat devices; if there were, they were not prohibited; or if prohibited, their presence was inadvertent) render the pleadings defective or abusive.

Arguments of the Parties

Defendants' Arguments

• Jurisdiction under the Consumer Credit Act: defendants submitted that many claims under section 140B of the 1974 Act should be pursued in the sheriff court (as local applications) and that the court lacks jurisdiction to hear section 140B applications in these group proceedings except in narrow circumstances; they argued that section 140B(2)(a) (debtor's application) and (4) limit forum and that s.140B(2)(c) does not extend to the present proceedings because sums paid or payable under finance agreements are not materially relevant to the core payment remedies sought.
• Prescription/time bar: defendants contended that many group members suffered loss at the date they purchased or acquired their vehicles so the five‑year prescriptive period ran from that date; the plaintiff had not averred sufficient facts to engage suspension or postponement rules (s.6(4), s.11(2), s.11(3)/(3A)) and had not made the specific averments required to avoid prescription, including particularity as to fraud or induced error; publicity about the "Dieselgate" scandal in 2015, defendants argued, put potential claimants on inquiry and thus the period to sue began well before the commencement of these proceedings.
• Fraud and misrepresentation pleadings: defendants argued that allegations of fraud were insufficiently specified (need to identify particular natural persons and specify the false statements and mens rea), that many alleged statements were broad marketing or editorial material and not actionable, and that statements might be opinion rather than fact. They sought exclusion from probation of broad or unparticularised fraud averments.
• Unlawful means conspiracy: defendants argued the pleaded conspiracy lacked essential ingredients — there were no specific averments that each defendant intended to harm identifiable claimants, no adequate specification of an agreement or combination, inadequate averment of requisite knowledge that the means were unlawful, and an insufficient causal connection between the alleged unlawful means and the loss complained of.
• Alternative/inconsistent defences: the defenders argued that they may properly plead alternative defences (no defeat devices; if any, exceptions apply; or inadvertence) and that the weaker‑alternative rule should not be used to strike down their defences at this stage.

Plaintiff's Arguments

• Consumer Credit Act jurisdiction: Plaintiff submitted that s.140B(2)(c) expressly allows an application under section 140B to be raised in any court where amounts paid or payable under a credit agreement are relevant, and that the group proceedings court has jurisdiction because such finance issues are relevant and are ancillary or incidental to the principal remedies sought; treating such applications as matters for many thousands of separate sheriff court actions would be impractical and contrary to efficient case management.
• Prescription: Plaintiff argued that many averments describe continuing acts or omissions (including continuing statutory duties and continuing misrepresentations such as Certificates of Conformity that were not withdrawn) so s.11(2) may postpone the start of the prescriptive period; alternatively, suspension under s.6(4) applies because the defenders engaged in concealment or induced error that prevented discovery of claims until shortly before proceedings were raised (notably, publicity/advertising about these proceedings in 2021).
• Fraud & conspiracy pleadings: Plaintiff submitted that, taken pro veritate and given the information asymmetry and ongoing document recovery process, the pleadings give fair notice of the case and are sufficiently specific for a mass‑action context; naming the signatories of the Certificates of Conformity and alleging board/officer responsibility gave fair notice and defendants know far more about the relevant internal actors than the Plaintiff and so cannot complain of lack of specification.
• Relevance of misrepresentation claims: Plaintiff maintained that Certificates of Conformity and sales/marketing materials were factual (or mixed fact/law) statements about emissions compliance and were directed at potential purchasers so an assumption of responsibility and duty of care (for negligent misstatement claims) could arise in the circumstances.

Court's Reasoning and Analysis

The court conducted a structured analysis divided broadly into (i) jurisdiction under the Consumer Credit Act; (ii) prescription/time bar issues under the Prescription and Limitation (Scotland) Act 1973 (as amended for relevant cohorts); (iii) relevancy and specification of fraud and misrepresentation averments; (iv) the unlaw ful means conspiracy cause of action; and (v) alternative/inconsistent averments and case management consequences.

On jurisdiction under the Consumer Credit Act 1974: The court interpreted section 140B(2)(c) purposively and concluded that the court has jurisdiction to determine applications under the 1974 Act where the amount paid or payable under a credit agreement is relevant to the "other proceedings" before it. The court rejected a narrow reading that would confine all such applications to the sheriff court (s.140B(2)(a) and (4) do require local applications in certain situations, but that does not oust the court's jurisdiction where the credit agreement sums are relevant to the principal proceedings). The court also noted that, alternatively, jurisdiction could be supported by the Civil Jurisdiction and Judgments Act 1982, s.22(4), where the matter is ancillary or incidental to the proceedings.

On prescription (sections 6 and 11 of the 1973 Act): The court emphasised careful identification of the act/omission relied upon and whether it is "continuing" for the purposes of s.11(2). It rejected the defenders' narrow gloss that s.11(2) applies only where loss continues to accrue; rather s.11(2) addresses continuing acts, neglects or defaults themselves. The court accepted that certain misrepresentations (for example, Certificates of Conformity) and duties under regulatory schemes may be of continuing character and that s.11(2) might therefore postpone the start of the quinquennium. The court also explained the scope of s.6(4) (fraud and error-induced suspension): fraud in that subsection is to be construed broadly (concealment, device or acting designed to prevent assertion of rights), and induced error can arise from words or conduct, active or passive. The "reasonable diligence" proviso was recognised as a factual inquiry for which the Plaintiff bears an initial onus to plead the circumstances bringing the matter within s.6(4), after which the defendants must plead facts bringing the matter within the "reasonable diligence" test. The court noted the relevance of press coverage (e.g. "Dieselgate") to inquiry but stressed the need for evidence and fact-finding before concluding that claimants were on inquiry such that prescription would bar their claims.

On fraud and specification: The court acknowledged the conventional strictness in fraud pleading (identify false statements, when, by whom, reliance and mens rea), but stressed that fair notice is context-dependent. In group proceedings, the court accepted a pragmatic standard: the representative party need only provide fair notice that is reasonable in the circumstances of a mass action where information asymmetry (defendants possess internal documentation) makes precise identification difficult for the representative party at pleading stage. The court found that the Plaintiff had identified the Certificates of Conformity (including signatories) and sales/marketing materials, and explained the underlying basis for alleging falsity (concealment of defeat devices), which provided fair notice adequate to require a proof before answer rather than dismissal or striking of those averments.

On negligent misrepresentation and duty of care: The court analysed the "assumption of responsibility" approach: it set a two‑part pragmatic threshold for negligent misstatement claims in the context of widely circulated commercial statements. The court held that a duty of care arise where (1) the statement contains factual material directly about emissions compliance (increasing foreseeability of reliance), and (2) the statement was made in a context where the defendant hoped to promote a transaction (sales brochures, point of sale materials, advertising aimed at purchasers). Applying that test the court concluded that certain misrepresentation claims against the manufacturers and sellers are properly arguable and suitable for enquiry; some aspects (notably aspects aimed only at remote publication or opinion) may be irrelevant and could be the subject of later pruning by interlocutor following further submissions and evidence.

On unlawful means conspiracy: The court undertook a detailed doctrinal review. It accepted that conspiracy is a distinct delict requiring a combination and an unlawful instrumentality that caused the claimant's loss. The court applied authorities (including general conspiracy principles) and concluded that the Plaintiff's averments—that defendants combined to present vehicles as compliant to purchasers by concealment of defeat devices and false representations—are sufficiently specific and directed at a definable class (potential purchasers/lessees) to give fair notice and to enable proof. The court rejected the defenders' submission that the claims were necessarily bound to fail for want of particularity regarding intention or knowledge: in the mass consumer context the court held it was plausible that the defendants' representations were directed to purchasers and that injury to purchasers was a likely consequence, so the conspiracy averments were not irrelevant and should proceed to proof (subject of course to proof and prescription analysis).

On alternative/inconsistent averments: The court held that defendants may plead several alternative contentions — that there were no defeat devices, or if there were they were exempted under regulatory exceptions, or that any prohibited devices were present inadvertently — and that, viewed in context, these are alternative mixed questions of fact and law and permissible. The court rejected an order striking out the defences on that ground at this stage.

Throughout the analysis the court emphasised the distinctive features of group proceedings: the representative nature of the action, the number of claimants, information asymmetry, and the need to balance fair notice against the practical burdens of overly detailed pleading in mass claims. The court repeatedly stressed that many contested questions (including prescription) are fact‑intensive and cannot be resolved on paper alone without evidence.

Holding and Implications

Holding (core procedural outcome): The court concluded that the Plaintiff's key averments (fraudulent misrepresentation, many negligent misrepresentation averments, and the unlawful means conspiracy cause of action) are not, on the pleadings, bound to fail and are suitable to proceed to proof before answer. The court also held that it has jurisdiction to entertain claims and remedies under section 140B of the Consumer Credit Act 1974 in the group proceedings under s.140B(2)(c) (and alternatively under s.22(4) of the Civil Jurisdiction and Judgments Act 1982) where sums paid or payable under credit agreements are relevant. The court refused to strike out the pleaded causes for lack of specification on the generality of the pleadings, subject to further case management.

Direct consequences for the parties:

• The Plaintiff's averments on fraud, negligent misrepresentation (as to specified statements such as Certificates of Conformity and certain marketing materials) and unlawful means conspiracy are to be proceeded with to evidential proof; they are not dismissed at this preliminary stage.
• Certain elements of the negligent misrepresentation pleaded against some defendants may be the subject of further targeted argument and potential refusal of probation, but the court declined to strike out wholesale at this stage; the court will receive further submissions and may make interlocutors before final probation decisions.
• The court accepts jurisdiction to determine s.140B remedies within the group proceedings where relevant; group members asserting CCA remedies may pursue them as part of these proceedings rather than being relegated to numerous separate sheriff court claims.
• Prescription issues remain a live, fact‑dependent question. The court did not hold that the material claims are preserved across the whole class; rather, it held that many prescription/submission questions require evidence and cannot be resolved on the papers. The plaintiff may seek to establish suspension or postponement of prescription under s.11(2) or s.6(4); defendants retain the right to advance time‑bar pleas at proof.
• Alternative and apparently inconsistent defences relied upon by defendants were not struck out; the court accepted they were, in context, permissible alternative legal/technical positions.

Final procedural order (as stated by the court): The court ordered that the case be put out so that the parties could make submissions on whether the content of the opinion requires refusal of probation to any averments and on what the next appropriate stage of procedure should be. No final determination on many contested preliminary pleas (in particular prescription and detailed refusal of parts of the pleadings) was made pending further case management and proof.

Concluding Observations

This opinion applies a pragmatic approach tailored to the realities of large‑scale representative litigation. The court balanced traditional pleading strictures (especially in fraud cases) against practical limitations faced by representative claimants and emphasised that many contested legal and factual questions (notably prescription, knowledge, and intention in conspiracy) are inherently evidential and require proof. The effect of the decision is to keep alive the Plaintiff's principal claims for the purposes of an evidential hearing while reserving to the court the ability, following further submissions and targeted interlocutors, to refuse probation to any averments that are ultimately shown to be legally irrelevant or insufficiently specified.
