This case is frequently cited as support for the idea that corporate law requires boards of directors to maximize shareholder wealth. However, one view is that this interpretation has not represented the law in most states for some time.

Among non-experts, conventional wisdom holds that corporate law requires boards of directors to maximize shareholder wealth. This common but mistaken belief is almost invariably supported by reference to the Michigan Supreme Court’s 1919 opinion in Dodge v. Ford Motor Co. — Lynn Stout

Dodge is often misread or mistaught as setting a legal rule of shareholder wealth maximization. This was not and is not the law. Shareholder wealth maximization is a standard of conduct for officers and directors, not a legal mandate. The business judgment rule [which was also upheld in this decision] protects many decisions that deviate from this standard. This is one reading of Dodge. If this is all the case is about, however, it isn’t that interesting. — M. Todd Henderson
