Company law governs the creation, operation, and dissolution of companies incorporated under UK statute, sitting at the intersection of contract, equity, and statute. Its central question is how the law should balance the interests of shareholders, directors, creditors, and the public when a separate legal personality — the company itself — stands between individuals and their commercial dealings. The Companies Act 2006 provides the primary statutory framework, but judge-made doctrine remains indispensable for filling its gaps.
Four doctrines define the subject. The separate legal personality principle, established in Salomon, is the bedrock: a company is a legal person distinct from its members, capable of owning property and incurring liabilities in its own name. Built on top of that sits the rule in Foss v Harbottle, which determines who may sue for a wrong done to the company and therefore controls access to the courts. Directors' duties — now codified in the Companies Act 2006 but still interpreted through equitable case law — ask how far those running the company must subordinate personal interests to the company's, and the doctrine of piercing the corporate veil asks when, in rare cases, the courts will look through separate personality altogether.
Several tensions remain live and examinable. Courts continue to wrestle with when, if ever, the corporate veil should be pierced after the Supreme Court's cautious treatment in Prest v Petrodel Resources, which preferred proprietary reasoning over veil-piercing. The scope of the no-profit and no-conflict duties remains contested, particularly whether they apply to former directors and in family-company contexts as shown by the divergence between Bhullar and earlier authorities. Minority shareholder protection also sits in flux: the statutory unfair prejudice remedy under s.994 is expanding in practice, raising questions about whether the equitable winding-up jurisdiction from Ebrahimi is becoming redundant.
