Corporations: Examples and Explanations (2015, 8th ed.), notes that "[c]orporation statutes are not all-encompassing; court decisions clarify and fill in the gaps of the statutes and the corporation's constitutive documents. The most important judicial gap-filling involves the fiduciary duties of directors, officers, and controlling shareholders. Common-law fiduciary principles that regulate abuse by those who control the corporation's decision-making machinery lie at the heart of corporate law." (section1.2.3, Role of Judge-Made Law, page 10)
