AXA General Insurance Ltd v HM Advocate [2011] UKSC 46
This case summary is about AXA General Insurance Ltd v HM Advocate [2011] UKSC 46. It is an important case for law students who are studying constitutional and administrative law. The case examines the boundaries of legislative competence of the Scottish Parliament and its impact on judicial review. The focus is on the Act relating to asbestos-related conditions and its challenge on the basis of irrationality and property rights under the European Convention.
Facts
Insurers challenged the Damages (Asbestos-related Conditions) (Scotland) Act 2009. The legislation responded to the conclusion in Rothwell that asymptomatic pleural plaques did not themselves constitute actionable damage in negligence. It made specified asbestos-related conditions actionable in Scotland, exposing insurers to additional liabilities under employers’ policies. The insurers argued that the Act infringed their property rights and fell outside the Scottish Parliament’s legislative competence. They also sought common law review on grounds including irrationality. The Supreme Court considered both the statutory limits of devolved legislation and the relevance of ordinary administrative-law grounds.
Legal Issue
Was the 2009 Act within the Scottish government’s legislative competence? Was the 2009 Act subject to judicial review for irrationality?
Held
The Supreme Court rejected the challenge. The Scottish Parliament was entitled to respond to what it regarded as a social injustice, and the measure did not impose an unjustified interference with the insurers’ property rights. The Court also rejected the use of ordinary irrationality or unreasonableness review to challenge Acts of the Scottish Parliament. Such Acts are subject to the competence limits established by the Scotland Act, but the legislature is not equivalent to an administrative decision-maker. The judgments discussed exceptional constitutional limits grounded in the rule of law. Those observations should be separated from the actual decision upholding the asbestos legislation and from the distinct requirements governing standing.
⭐ Legal Principle
Acts of the Scottish Parliament are subject to statutory limits on legislative competence, including applicable Convention rights. AXA rejected their review on ordinary administrative grounds of irrationality, while recognising the constitutional importance of the rule of law and the courts’ supervisory role.
Significance
AXA distinguishes a democratically elected devolved legislature from an ordinary administrative authority. Acts of the Scottish Parliament remain subject to statutory competence limits, including applicable Convention requirements, but not routine Wednesbury review. Judicial observations about fundamental attacks on the rule of law should be identified as constitutional reasoning, not confused with the actual outcome. The insurers’ challenge failed. The case also contributes to the development of standing in Scottish public law, distinct from whether a Convention interference is justified.
Common exam questions about this case
Why was the Scottish Parliament treated differently from a local authority?
It is a democratically elected legislature exercising a general law-making function within the Scotland Act framework. The court therefore rejected ordinary irrationality review of its legislation. That did not make it sovereign in the Westminster sense: statutory competence limits and applicable rights constraints continued to be judicially enforceable.
Did the insurers win because their property interests were affected?
No. An interference with economic interests did not by itself establish an unjustified violation of property rights. The legislation pursued a social-policy response to asbestos-related conditions, and the legislature had a wide area of judgment in that field. The Court upheld the measure rather than treating the insurers’ financial impact as decisive.
What error should be avoided when describing Rothwell?
Rothwell held that asymptomatic pleural plaques were not actionable damage in the relevant negligence claims. The Scottish legislation responded by making specified asbestos-related conditions actionable. Reversing Rothwell’s outcome would remove the reason for the legislation and distort the constitutional dispute considered by the Supreme Court.
