Key legal question
How the policy term 'infirmity' in the CGA must be interpreted for the 10-month limitation.
Extracted holding
The term is governed by the contractual definition in art. 1 CGA: a definitive loss or impairment of a function or organ.
Extracted reasoning
Contract terms expressly incorporated into the policy are interpreted according to their conventional meaning within the contract as a whole. The insurer had to prove an infirmity within the contractual definition, not merely a pre-existing psychiatric disorder or prior treatment.
