Construing a policy of insurance

As the policy is a commercial contract, the Court should, in construing it, “ask what a reasonable businessperson would have understood [the relevant] terms to mean”: Electricity Generation Corporation t/as Verve Energy v Woodside Energy Ltd (2014) 251 CLR 640; [2014] HCA 7 (Electricity Generation) at [35].

The task is an objective one; it involves identifying the imputed intention of the parties, by reference to the contractual text construed in the light of its context and purpose: Electricity Generation at [35]; Mount Bruce Mining Pty Ltd v Wright Prospecting Pty Ltd (2015) 256 CLR 104; [2015] HCA 37 (Mount Bruce) at [46]-[51] and [108]-[109]; Victoria v Tatts Group Ltd [2016] HCA 5; (2016) 90 ALJR 392 at [51]-[75]; Simic v New South Wales Land and Housing Corporation (2016) 260 CLR 85; [2016] HCA 47; (2016) 91 ALJR 108 at [18].

Importantly, in their joint judgment in Mount Bruce, French CJ, Nettle and Gordon JJ said (at [48]) that: Ordinarily, this process of construction is possible by reference to the contract alone. Indeed, if an expression in a contract is unambiguous or susceptible of only one meaning, evidence of surrounding circumstances (events, circumstances and things external to the contract) cannot be adduced to contradict its plain meaning. (Footnote omitted)

Their Honours also emphasised that “context” may be discerned from the entire text of the contract in question: at [46].
