Corporate & Commercial Litigation. Morris Nichols lawyers have litigated many of the landmark cases that established the principles of Delaware corporate law and defined the fiduciary duties governing boards of directors of many major corporations in the United States. From the seminal Revlon case to the more recent landmark decision in MFW, we represent many of the world’s largest companies in litigation of national significance.

We advocate on behalf of corporations, directors, substantial stockholders, partnerships, limited and general partners, and limited liability companies in lawsuits involving challenges to mergers, acquisitions and financing transactions; takeover battles and proxy contests; busted deals; as well as class and derivative actions. We also represent special committees of independent directors in connection with reviewing conflict transactions and with the investigation of potential and pending derivative claims. In addition, we routinely handle matters involving complex valuations of Delaware corporations and alternative entities, as well as statutory proceedings before the Delaware Court of Chancery such claims for inspection of books and records; claims by directors for advancement and indemnification of their legal fees; and claims to compel an annual stockholders’ meetings.

Our practice focuses on issues of corporate governance and those that are more transactional in nature, including advice concerning mergers, acquisitions, spin-offs, financings and other complex transactions. Our work ranges from suggesting simple solutions based on our Delaware experience to providing formal legal opinions to designing and structuring complex transactions for businesses and investors throughout the world. We also regularly serve as special counsel to boards of directors and board committees, particularly in situations involving potential conflicts of interest.
