The appellants appealed the dismissal of their motion to certify a class action against the manufacturer of the drug Celexa, alleging a failure to warn that the drug is a teratogen.
The Divisional Court found that the motion judge made palpable and overriding errors by concluding the appellants had abandoned general causation as a common issue and by analyzing the duty to warn in isolation from general causation.
The appeal was allowed, the decision set aside, and the certification motion was remitted to be heard afresh by another judge.
