Lloyds TSB General Insurance Holdings and others (Original Respondents And Cross-appellants) v. Lloyds Bank Group Insurance Company Limited (Original Appellants and Cross-respondents

An aggregation clause in a commercial insurance policy must be construed in a balanced manner by giving effect to the particular unifying factor chosen by the parties. Where the defined act or omission must give rise to the insured civil liability, systemic failures lying behind individual breaches cannot aggregate the resulting claims.

A related series of acts or omissions requires the relationship specified or necessarily implied by the clause. Similarity or a common underlying origin is insufficient. Under this clause, the acts or omissions had to operate together to cause each claim. Separate failures to advise separate investors therefore remained separate claims, each subject to the deductible.

The insured companies paid more than £125 million to settle about 22,000 claims arising from the mis-selling of personal pensions. They sought indemnity under a professional indemnity policy. No individual claim exceeded the £1 million deductible, but the insureds contended that the claims could be aggregated as resulting from a single act or omission, or a related series of acts or omissions.

Moore-Bick J held that failures in training and monitoring permitted aggregation: [2001] Lloyd's Rep IR 237. The Court of Appeal rejected the single-act argument but held that the individual breaches formed a related series because they shared an underlying cause: [2001] EWCA Civ 1643; [2002] Lloyd's Rep IR 113.

The central issue was whether the aggregation wording permitted the claims to be treated as one claim for application of the deductible.

1. Disposition. The House unanimously allowed the insurer's appeal, dismissed the insureds' cross-appeal and answered both preliminary questions in the negative. Lord Hoffmann and Lord Hobhouse delivered the principal speeches. Lord Nicholls, Lord Millett and Lord Walker agreed with their reasons.

2. Construction of aggregation clauses. Per Lord Hobhouse, such clauses may favour either party and must be construed in a balanced fashion. Professionally drafted insurance contracts commonly offer established alternative forms of aggregation wording. The parties' selection among them forms part of their bargain and must be respected. Per Lord Hoffmann, the description of the designated unifying factor is therefore critical: general language produces wider aggregation, while narrow language must retain its intended effect.

3. Single act or omission. Per Lord Hoffmann and Lord Hobhouse, the policy definition required the relevant act or omission to be the breach which caused the third party's financial loss and gave rise to the insured civil liability. The systemic absence of adequate training or monitoring was too remote. Liability under rule 3.4(4)(a) of the LAUTRO Rules arose upon each representative's failure to give best advice to an investor. The obligation to ensure compliance created the company's own contingent or absolute liability; it did not make the company vicariously liable for the representative. There were consequently as many material acts or omissions as there were claims.

4. Related series. Per Lord Hoffmann, the words “related series” could not introduce an unstated and much broader upstream unifying factor which contradicted the clause's narrow primary concept. The causal relationship specified by the clause was downstream: the acts or omissions had to act together to result in each of the claims. Mere similarity, repetition or descent from a common systemic failure was insufficient.

   Lord Hobhouse likewise held that the clause was not an originating-cause clause. The parties had omitted the wider formulations used in other policies, such as attribution to a single source or originating cause. The common origin and similar character of the individual failures therefore could not aggregate them.

5. Each investor's claim arose from a separate contravention of rule 3.4(4)(a), rather than from one act or from the same combination of related acts. Every claim remained subject to its own £1 million deductible.

1. House of Lords: The insurer's appeal was allowed unanimously, the insureds' cross-appeal was dismissed and the Court of Appeal's conclusion on aggregation was reversed: [2003] UKHL 48.
2. Court of Appeal: The court rejected aggregation by reference to a single act or omission, but dismissed the insurer's appeal because it considered that the individual breaches constituted a related series sharing a common underlying cause: [2001] EWCA Civ 1643; [2002] Lloyd's Rep IR 113.
3. Commercial Court: Moore-Bick J held that failures to establish adequate training and monitoring arrangements caused the claims and permitted them to be aggregated: [2001] Lloyd's Rep IR 237.
