AXA General Insurance Ltd & Ors v Lord Advocate & Ors (Scotland)

Factual and Procedural Background

The Appellants, a group of insurance companies, sought to overturn the Damages (Asbestos-related Conditions) (Scotland) Act 2009 (“the 2009 Act”). The Act reverses the House of Lords decision in Rothwell v Chemical & Insulating Co Ltd by declaring that asymptomatic pleural plaques, pleural thickening and asbestosis constitute actionable personal injury. The insurers argued that the statutory re-classification would expose them to very substantial liabilities under historic employers’ liability policies.

Following extensive debates (22 days before Judge Emslie and 8 days before the Inner House), the Lord Ordinary dismissed the insurers’ petition ([2010] CSOH 2). The Inner House largely upheld that decision ([2011] CSIH 31) but refused standing to eight individuals diagnosed with pleural plaques. The insurers appealed to the Supreme Court; the Lord Advocate and those eight individuals cross-appealed. Written interventions came from authorities in Northern Ireland and a non-governmental organisation; oral submissions were also received on behalf of the Welsh Government.

Legal Issues Presented

1. Whether the 2009 Act is incompatible with Article 1 of Protocol 1 to the European Convention on Human Rights (“A1 P1”) and therefore outside the legislative competence of the Scottish Parliament under section 29(2)(d) of the Scotland Act 1998.
2. Whether, at common law, the Act is susceptible to judicial review as an unreasonable, irrational or arbitrary exercise of legislative power.
3. Whether the eight individual pleural-plaque claimants are “directly affected” so as to have standing to participate under Rule 58.8(2) of the Court of Session Rules.

Arguments of the Parties

Appellants’ Arguments

• The Act retroactively alters insurers’ contractual liabilities, amounting to an unjustifiable interference with their possessions contrary to A1 P1.
• Retroactivity is “manifestly without reasonable foundation”; Parliament could have created a publicly-funded scheme instead of burdens on insurers.
• Even if Convention-compliant, the Act is irrational at common law because it compels private entities to fund a social policy objective.
• The eight individual respondents lack title or interest: their asserted rights depend entirely on the validity of legislation under attack.

Respondents’ Arguments

• Insurers are not “victims” under Article 34 ECHR: any impact is indirect and contingent on future litigation.
• Alternatively, any interference pursues a legitimate social aim—remedying perceived injustice to asbestos-exposed workers—and is proportionate.
• Acts of the Scottish Parliament can only be reviewed on the express grounds in section 29; irrationality review is unavailable.
• The pleural-plaque claimants are “directly affected” because the insurers seek relief that would extinguish their causes of action.

Court's Reasoning and Analysis

Victim status & possessions: Insurers face real, not hypothetical, liabilities intended by the legislature; their financial reserves are “possessions” for A1 P1 purposes.

Interference: The Act retrospectively enlarges liabilities under historic policies, constituting an interference with peaceful enjoyment of possessions.

Lawfulness: Despite retroactive effect, the Act is “law” within the Convention meaning; rule-of-law concerns are addressed by excluding determined or settled claims.

Legitimate aim: Parliament sought to correct a perceived social injustice—loss of compensation for asbestos-exposed workers—an aim squarely within social-policy discretion.

Proportionality/fair balance:

• Insurers had never enjoyed a settled expectation; the common law had been uncertain until Rothwell.
• The Act reinstated a long-standing practice (20 years of settled claims) rather than creating wholly new liabilities.
• Claims remain subject to proof of negligence and normal defences; only the “actionability” hurdle is removed.
• Insurance is inherently risk-based; unforeseen disease definitions fall within the commercial risk undertaken.

Common-law irrationality:

• Acts of the Scottish Parliament possess plenary competence save for limits in s 29(2) Scotland Act.
• Courts cannot review such Acts for “irrationality” absent breaches of fundamental rights or rule-of-law principles.
• No such exceptional circumstances existed.

Standing of third-tenth respondents: The eight pleural-plaque claimants are “directly affected” under Rule 58.8(2) because success for the insurers would extinguish their causes of action; a rights-based private-law test is inapposite in public-law review.

Holding and Implications

Holding: APPEAL DISMISSED; CROSS-APPEAL ALLOWED. The 2009 Act is within the legislative competence of the Scottish Parliament and compatible with A1 P1. The eight individual claimants are entitled to participate in the proceedings.

Implications: Insurers remain potentially liable for pleural-plaque claims in Scotland; pleural-plaque victims retain statutory causes of action. The judgment clarifies (1) the breadth of the Scottish Parliament’s margin in social-policy legislation, (2) the limited scope for common-law review of devolved statutes, and (3) a modern, interest-based approach to standing in Scottish judicial-review proceedings. No new precedent is set on damages quantum, but significant guidance is provided on constitutional review and procedural participation.
