Doctrine of Ultra Vires and Constructive Notice — Company Law Notes

Doctrine of Ultra Vires and Constructive Notice

In 1875 a railway-carriage company signed a contract to finance a railway line in Belgium — a perfectly good deal. Yet the House of Lords struck it down as void from the start, because building railways was not in the company’s object clause. The company had no power to do it, so even its own shareholders could not later approve it.

Doctrine of ultra vires

Ultra vires [Latin: beyond the powers]. A company’s capacity is limited by its object clause (topic 3). Any act outside the objects is ultra vires the company — it is void ab initio [void from the beginning] and cannot be ratified even by all the shareholders. The doctrine protects two groups:

Shareholders — their money is used only for the purposes they signed up for.
Creditors — the company’s funds are not diverted to unauthorised ventures.

Key consequences:

An ultra vires contract is void; neither party can enforce it.
Ultra vires acts cannot be ratified, even by unanimous consent.
Property acquired under an ultra vires transaction still belongs to the company.
Directors who apply funds ultra vires may be personally liable to replace them.

Distinguish ultra vires the company (void, unratifiable) from ultra vires the directors (act within company’s powers but beyond directors’ authority — this can be ratified by the members).

Note the modern dilution: to reduce hardship, companies now draft very wide object clauses, and s.4 lets objects be stated broadly, so pure ultra vires disputes are rarer today — but the doctrine remains examinable and alive for gifts/donations and clearly foreign objects.

Doctrine of constructive notice

The MOA and AOA are public documents, registered and open to inspection. The law therefore presumes that everyone dealing with the company has read and understood them — this is constructive notice [notice the law imputes to you whether or not you actually read]. An outsider cannot say “I did not know the articles required X”; he is deemed to know. It is the company’s shield.

Section 4(1)(c): the memorandum must state “the objects for which the company is proposed to be incorporated and any matter considered necessary in furtherance thereof.”

In Simple Terms: A company can legally do only what its object clause allows; anything beyond is dead on arrival and nobody can revive it (ultra vires). And because the MOA/AOA are public, the law treats every outsider as if he has read them (constructive notice).

🧩 WORKED EXAMPLE — company switches to making gold ornaments

Facts. A company’s object is to manufacture mechanical spares. It now wants to manufacture and sell gold ornaments.

Rule. Making gold ornaments is outside the objects; the act is ultra vires and void unless the object clause is first altered by special resolution (s.13).

Apply. Without altering the objects, contracts for the new business are void and unenforceable.

Conclusion. Advise the company to alter its object clause (special resolution) before starting the new venture; until then the activity is ultra vires.

Case Laws

A. Lakshmanaswami Mudaliar v LIC (1963) — Indian case; a donation outside the objects is ultra vires and void.
[C-10] Kotla Venkataswamy v Rammurthy (1934) — outsider bound by constructive notice of the articles.
