In re: Liquid Aluminum Sulfate Antitrust Litigation, MDL No. 2687 (D.N.J.)

Lieff Cabraser served as a member of the Court-appointed Plaintiffs’ Steering Committee in litigation involving liquid aluminum sulfate or “Alum.” Alum is a chemical used by municipalities and in industry for treating water, controlling algae in lakes and ponds, manufacturing paper and pulp, and other uses.

The direct purchaser plaintiffs alleged that the defendant manufacturers of Alum conspired to raise and fix the prices of Alum over a fourteen-year period, allocated customers and submitted artificially inflated bids, resulting in overcharges to municipalities and other buyers of Alum.

Over the course of the litigation, the direct purchaser plaintiffs reached settlements with each of the defendants, ultimately totaling over $105 million.
