The fiduciary duties of loyalty and care, the corporate opportunity doctrine and the business judgment rule are introduced in the context of three vignettes drawn from decided cases that explore: a classic test of loyalty when one partner elects to take advantage of an opportunity the partnership may also be able to pursue (Meinhard v. Salmon); the care and procedure directors should employ when approving a merger or sale of the company (Smith v. Van Gorkum); and the board's role and process in hiring, firing and severance decisions (Ovitz at Disney).
