The plaintiffs sought certification of a national class action against the defendants regarding alleged defects and failures to warn associated with Allergan breast implants, specifically concerning risks of BIA-ALCL, premature rupture, and ASIA/BII.
The court found that the plaintiffs met all the criteria under section 5(1) of the Class Proceedings Act, 1992, including demonstrating a plausible methodology for their claims through expert evidence, despite significant scientific debate.
The action was certified against all defendants, expanding a previous partial certification order.
