Harry Hoaas and Larry Griffiths were shareholders in Grand Casino, Inc. which owned and operated a casino in Watertown, South Dakota. Griffiths owned 51 percent of the stock and Hoaas 49 percent. Hoaas managed the casino, which Griffiths typically visited once a week. At the end of 1997, an accounting showed that the cash on hand was less than the amount posted in the casino's books. In October 1999, Griffiths did a complete audit. Hoaas was unable to account for $135,500 in missing cash. Griffiths then kept all of the casino's most recent profits, including Hoaas's $9,447.20 share, and, without telling Hoaas, sold the casino for $100,000 and kept all of the proceeds. Hoaas filed a suit in a South Dakota state court against Griffiths, asserting, among other things, a breach of fiduciary duty. Griffiths countered with evidence of Hoaas's misappropriation of corporate cash. What duties did these parties owe each other? Did either Griffiths or Hoaas, or both of them, breach those duties? Explain. 314 N.W.2d 61 (2006).
