Duomatic principle
The Duomatic principle is a principle of English company law relating to the informal approval of actions by a company's shareholders (and, potentially, directors). The principle is named after one of the earlier judicial decisions in which it was recognised: Re Duomatic Ltd [1969] 2 Ch 365, although in that case Buckley J was approving an older statement of the law from the decisions in In re Express Engineering [1920] 1 Ch 466 and Parker and Cooper Ltd v Reading [1926] Ch 975.
