John is a partner in the Corporate & Business Litigation Group, and a former member of the Firm’s Executive Committee.  John’s practice includes representing investors, directors and officers, corporations, limited liability companies and general and limited partnerships in litigation concerning mergers and acquisitions and other complex commercial disputes.

John routinely defends corporate defendants against stockholder lawsuits and has significant experience with takeover litigation. Family Dollars’ $8.5 billion acquisition of Dollar Tree, the Men’s Wearhouse $1.8 billion acquisition of Jos. A. Bank, Air Products’ $7 billion takeover attempt of Airgas, the Bear Stearns merger with JPMorgan in the midst of the 2008 financial crash, and Caremark Rx, Inc.’s $27 billion merger with CVS Corporation are just some of John’s representative matters.  

John also routinely represents both individual and corporate clients who need to prosecute or defend corporate governance disputes including, for example, contests for board control, demands for appraisal or similar valuation disputes, demands for books and records, advancement and indemnification, requests for dissolution and receiverships, and a broad variety of other corporate governance disputes.  John has extensive trial experience and has received the National Institute for Trial Advocacy, Advocate designation awarded to individuals who have devoted substantial time to trial practice continuing education.  

John’s litigation practice is complimented by his advisory work and he also routinely advises boards of directors and special committees in internal investigations, and stockholder derivative demands.

At the invitation of the Honorable Andre G. Bouchard, Chancellor of the Delaware Court of Chancery, John serves on the Delaware Court of Chancery Rules committee, a body charged with regularly reviewing the Court’s rules and practices and working with the Court to ensure that the Court’s rules and practices remain optimal. He also frequently writes and speaks on emerging issues in corporation law both nationally and internationally. Most recently he partnered with the Honorable Randy J. Holland, Justice of the Delaware Supreme Court, and the Taiwan Corporate Governance Association in a project to develop an international corporate law database that will serve as a resource for judges assigned to Taiwan’s newly developed business court. 

In 2015, John was invited to deliver the key note address at the Taiwan Corporate Governance Association’s 2015 International Summit on Corporate Governance, a two-day event focused on strengthening internal and external corporate governance mechanisms. The corporate governance summit was attended by members of Taiwan’s Securities and Futures Exchange, members of Taiwan’s Judicial and Legislative branches and a panel of international corporate governance experts and academics from various countries,including the United States, Japan, South Korea, Hong Kong, Singapore and Australia.

Since 2020, he has been recognized by The Legal 500 US for his M&A litigation defense work.
