Precedent-Setting Wins

Southwick is responsible for some of the country’s most significant rulings in the past 20 years.

In Brand et al v. Promega
, Southwick represented a group of minority shareholders against privately held Promega Corporation and its founder, CEO, and majority owner on a claim of shareholder oppression. Southwick was first chair in a four-week bench trial and forced a post-trial settlement and $300 million+ buyout in one of the largest shareholder oppression recoveries on record.

In Dial Corporation et al v. News Corp. et al.
, Southwick took on industry giant, News Corp., when he served as co-lead counsel in this class action alleging federal monopolization claims. A settlement agreement was signed on the first day of trial requiring the defendants to pay $250 million to a class of packaged goods manufacturers.

In Vitamin C Antitrust Litigation
, Southwick secured a $54.1 million jury verdict in an antitrust price-fixing class action brought on behalf of direct purchasers of vitamin C against two Chinese vitamin C manufacturers in the first-ever case in which mainland Chinese companies were successfully sued under US antitrust law. The verdict was tripled as required by law and, after adjusting for $32.5 million in settlements with other defendants, a final judgment of $147 million was entered against the defendants. This antitrust price-fixing class action was later reviewed by the United States Supreme Court, which issued a unanimous 9-0 decision in favor of the plaintiffs. Following more proceedings before the Second Circuit, the case is currently back before the Supreme Court on a second round of certiorari petitions.

Community Involvement and Recognition:

Southwick spends a good amount of time each year litigating matters pro bono. For Houston’s historic Alley Theater, the oldest professional theatre company in Texas and the third-oldest resident theatre in the country, Southwick represented Alley pro bono in insurance litigation related to Hurricane Harvey-caused business interruption. Southwick helped secure a partial summary judgment ruling on behalf of Alley and a few months later the team again scored a victory for the theater when they settled the final piece of the litigation–terms of this settlement are confidential.

Southwick is also a member of the Board of Advisors of the Syracuse University College of law. plant.
