JOSEPH MACKAY AGAINST NISSAN MOTOR CO LTD AND OTHERS

Factual and Procedural Background

The Applicant applied for permission to bring group proceedings in the Court of Session concerning the alleged fitting of prohibited defeat devices to certain diesel vehicles manufactured by two automotive groups, herein referred to as Company A and Company B. The Applicant also sought to be authorised as the representative party on behalf of approximately 8,500 persons claiming loss due to this alleged conduct. The proposed Defenders are various companies within the two automotive groups. Both applications—permission to bring group proceedings and authorisation as representative party—were opposed by the Defenders and were heard by the court.

Legal Issues Presented

1. Whether the claims raise issues of fact or law that are the same as, or similar or related to, each other (commonality test).
2. Whether the representative party has made all reasonable efforts to identify and notify all potential group members of the proceedings.
3. Whether a prima facie case has been demonstrated.
4. Whether the group proceedings represent a more efficient administration of justice than individual proceedings (superiority test).
5. Whether the proposed proceedings have real prospects of success.
6. Whether the Applicant is a suitable person to be authorised as representative party, considering abilities, interests, independence, conflicts, competence, and financial resources.

Arguments of the Parties

Applicant's Arguments

• The group proceedings procedure promotes access to justice and is intended to conveniently hear claims such as those concerning defeat devices in vehicles.
• The claims raise common or related issues regarding excessive nitrogen oxide emissions from certain diesel engines in vehicles manufactured by Company A and Company B, justifying a combined group proceeding.
• Significant efforts have been made to notify potential group members, including extensive advertising.
• The Applicant has demonstrated a prima facie case with real prospects of success, sufficient to meet the threshold for permission to proceed.
• It is premature and inappropriate to require detailed specification of individual claims or complex technical issues at this stage.
• The Applicant relies on funding from an experienced litigation funder with sufficient financial resources to meet any adverse expenses awards.
• The Applicant is independent, has a personal interest as a member of the group, and is suitable to act as representative party despite lacking special expertise.

First to Fifth Defenders' Arguments

• The commonality test is not met as the group includes purchasers and lessees of vehicles from two separate manufacturers with distinct and varying technical characteristics.
• The application lacks adequate specification, including details of loss, and many claims appear time-barred by prescription.
• The group proceedings would not efficiently administer justice due to the heterogeneity of claims and the complexity of evidence required.
• The application fails to demonstrate real prospects of success, given the lack of specificity and the complexity of the claims.
• The group register is flawed, containing duplications, irrelevant vehicles, and insufficient detail for the Defenders to investigate claims.
• Allegations of fraudulent misrepresentation lack the necessary specificity required by law.
• The Applicant has not sufficiently demonstrated the ability to fairly represent a diverse group, nor adequately disclosed funding arrangements to satisfy indemnity concerns.

Sixth to Tenth Defenders' Arguments

• The Applicant has not shown that reasonable efforts were made to identify and notify all potential group members.
• The application fails to specify the case properly, raising issues of duplication, jurisdiction, and inadequate information about group members.
• The claims are too broadly and generically pleaded, without identifying specific vehicles, engine types, or defeat devices.
• The Applicant has not demonstrated a prima facie case under relevant EU law, nor quantified the claims.
• Many claims are time-barred by prescription.
• The application does not demonstrate that group proceedings would be a more efficient administration of justice.
• The Applicant has not adequately addressed funding and indemnity concerns, particularly regarding the financial capacity of the litigation funder.

Court's Reasoning and Analysis

The court undertook a stepwise analysis of the statutory and procedural criteria for granting permission to bring group proceedings and authorising a representative party. It first considered the commonality test, finding that despite the presence of two distinct groups of Defenders, there were sufficiently related factual and legal issues arising from the alleged fitting of defeat devices in diesel engines across vehicles of both companies. The court acknowledged the complexity but concluded that the issues were "related" rather than requiring identity.

Regarding notification efforts, the court accepted the Applicant's submissions that reasonable steps, including extensive advertising, had been taken to identify and notify potential group members, with no effective challenge from the Defenders.

On the prima facie case, the court emphasized the limited nature of the test at this stage, requiring only the appearance of a serious question to be tried, distinct from the merits or real prospects test. The court found that the Applicant met this threshold despite acknowledged deficiencies in specification and potential difficulties which could be managed through case management.

The court held that group proceedings represented a more efficient administration of justice compared to thousands of individual claims, aligning with the policy aims of the governing legislation to improve access to justice.

In assessing real prospects of success, the court applied the test from Wightman, concluding that while success was not probable, the claims had real and substantial prospects sufficient to proceed.

For the appointment of the representative party, the court reviewed the criteria set out in the Rules of Court. The Applicant was found to be independent, with a personal interest and no current conflict of interest. Although lacking special expertise and not having demonstrated active engagement with legal advice, the court accepted that the Applicant could competently act in the role. The financial resources, supported by a reputable litigation funder with adequate assets and experience, satisfied the court that the Applicant could meet any expenses awards.

The court noted some concerns about the adequacy of demonstration that the Applicant would act fairly and adequately in the interests of the group but found no evidence of conflict or unfairness at this stage. It emphasized that a relatively low bar applies to suitability to ensure the group proceedings mechanism functions effectively.

Holding and Implications

The court's final decision was to GRANT PERMISSION for the Applicant to bring group proceedings, to be known as the "Renault Nissan NOx Emissions Group Proceedings," and to AUTHORISE the Applicant to act as the representative party on behalf of the group.

The direct effect is that the group proceedings will proceed, allowing the claims of approximately 8,500 persons to be heard collectively. The decision does not establish new precedent but reflects the application of existing statutory and procedural criteria to the facts presented. The court indicated that future case management will address issues of specification, individual claims, and potential conflicts as the proceedings progress.
