In this "bet the company" litigation, we represented a quarry owner in approximately 350 lawsuits and as to another 150 claimants, in which the plaintiff residential and commercial building owners sought $55 million in damages. The plaintiffs argued the concrete was failing due to alkali-carbonate reactivity (ACR) caused by our client's quarry rock. In three years of hard fought litigation, we defeated class action certification and crafted a defense strategy that challenged both the legal bases and factual premises of the plaintiffs' claims, leading to a settlement for a fraction of the claimed damages. Concurrently, we worked with the client's carriers to obtain coverage for most of the client's settlement contribution share, then utilized a class action for settlement purposes only and resolved all asserted and unasserted claims related to ACR, except for a few claimants who opted out of the settlement.
