Experience

  • Bill has tried dozens of cases involving disputes representing business entities, majority owners, and minority owners. In a seminal case twenty-five years ago, Bill won the first major shareholder oppression case under the revised Minnesota Business Corporation Act, recovering over $33 million for his clients. In 2005 Bill's advocacy resulted in a court ordering that his client who had been forced out of a small business be paid nearly $300 million for his interest. In 2008 he led a trial team that obtain a judgment of nearly $60 million for limited partners in a dispute with general partners and trustees in a complex series of trusts and limited partnerships in a western state. In 2009 Bill successfully defended the world's largest granite quarrier and fabricator in a lawsuit brought against it by minority shareholders.
  • In the areas of non-competes and trade secrets, Bill regularly tries temporary injunction trials and trials on the merits throughout the country enforcing his clients' non-compete agreements. In the past few years he has successfully defended three different misappropriation of trade secret cases; in each case the plaintiff sought to recover $100 million or more, and in each case the plaintiff recovered nothing.
  • Recently Bill led a team which obtained a decision from the Delaware Court of Chancery which expanded the range of fiduciary duties of parent corporations. And in early 2010 he negotiated a $56 million settlement of a breach of fiduciary claim which creditors of a bankrupt corporation brought against its former chief financial officer.
  • Beyond business litigation, Bill represented U.S. Senator Al Franken in three cases before the Minnesota Supreme Court in connection with the canvass of the 2008 election. He also represented Planned Parenthood of Minnesota in the trial and appeals of its successful challenge to a Minnesota statute which was ultimately resolved by the U.S Supreme Court.
