The Court of Appeal considered the doctrines of waiver by election and waiver by estoppel. The former involves the exercise of a right to choose between inconsistent remedies and requires unequivocal conduct. Waiver by estoppel occurs where an insurer unequivocally represents that it accepts liability or will not rely on breach of a condition precedent and the insured has detrimentally relied on the representation such that it would be inequitable for the insurer to resile from his representation. The Court said that although an insurer could not equivocate for a long time whilst giving the insured the impression that it was treating the claim as covered by its policy, Euclidian was entitled to a reasonable amount of time to consider the situation including awaiting answers from Kosmar as to why there was such a delay in giving notice. The Court of Appeal disagreed with the first instance judge, stating that when considering breach of a procedural condition precedent such as the notice clause, the relevant doctrine was not election but estoppel. The Court found that there was no evidence that the insurer had decided to waive the need for Kosmar to comply with the notice provision and the September Communications were not unequivocal declarations of Euclidian’s position. The fact that there was no unequivocal communication by the insurer meant that a claim based on waiver by estoppel also failed. Kosmar was therefore not entitled to an indemnity from its insurer.
Although on reading the facts of this case, one might understand why Kosmar believed its insurer to have agreed to ignore the breach of the notice provision, the Court of Appeal’s decision makes clear that unless an insurer has clearly stated its willingness to deal with the claim an insured will not be excused from the consequences of its breach of procedural condition precedent.
