Do Articles of Association Override a Shareholders’ Agreement?
Articles of Association do not automatically override a shareholders’ agreement in every situation. The two documents have different legal functions.
The Articles govern the company’s formal procedures and bind the company and its members. A shareholders’ agreement is a private contract that binds only the people or organisations that are parties to it.
If the documents conflict, a company decision may be valid under the Articles while still causing one or more shareholders to breach the shareholders’ agreement.
The Articles form part of the company’s constitution and contain the formal rules for running the company.
They commonly cover:
Under section 33 of the Companies Act 2006, the company’s constitution binds the company and its members.
A person who becomes a registered shareholder will generally become subject to the Articles in their capacity as a member.
A shareholders’ agreement is a private contract between some or all of the shareholders. The company may also become a party to it.
It may cover:
Only the parties to the agreement are normally bound by it. A new shareholder does not automatically become a party simply because they acquire shares.
The result depends on the particular provision and action involved.
For example, the Articles may allow a company decision to be approved by shareholders holding 75% of the votes. The shareholders’ agreement may state that the same decision requires unanimous approval.
If shareholders holding 75% approve the decision:
This is why neither document can be said to override the other in every circumstance.
Generally, yes. The Articles govern the formal corporate procedures that directors and shareholders must follow.
They determine matters such as:
A shareholders’ agreement does not automatically amend these constitutional rules.
The shareholders’ agreement may contain a priority clause stating that its terms take priority if it conflicts with the Articles.
Such a clause can be effective as a contractual promise between the parties. It may require the shareholders to:
However, the clause does not automatically rewrite the Articles or alter the company’s formal procedures. Until the Articles are properly amended, a conflicting corporate action may still be valid even though it breaches the agreement.
No. Signing a shareholders’ agreement does not itself amend the Articles.
To change the Articles, the company must normally:
The required documents must normally be filed within 15 days of the relevant event.
The parties may agree to take steps to amend the Articles, but a private contract cannot make an unlawful company action valid.
A shareholders’ agreement cannot:
Any provision requiring an unlawful action may be unenforceable.
If a shareholder breaches the shareholders’ agreement, the other parties may seek contractual remedies.
Depending on the agreement and circumstances, these may include:
If the company breaches its Articles, different company-law remedies may be available, including challenging the validity of a decision or seeking an order requiring the company to follow its constitution.
A new shareholder will generally become bound by the Articles when entered in the company’s register of members.
They will not normally be bound by the shareholders’ agreement unless they sign:
The Articles and shareholders’ agreement should require a buyer to join the agreement before a share transfer is approved or registered, where appropriate.
If the company has not signed the shareholders’ agreement, it will not normally be contractually bound by it.
The agreement may still require its shareholder parties to use their voting rights to cause the company to take specified actions. However, directors must continue to exercise independent judgement and comply with their statutory duties.
Adding the company as a party may make some obligations easier to enforce, but the company cannot agree to restrictions that unlawfully prevent it from exercising statutory powers.
Important constitutional protections are often included in the Articles, while more detailed or confidential arrangements are included in the shareholders’ agreement.
Matters commonly addressed in both include:
The provisions should be drafted consistently.
A company can reduce the risk by:
Articles of Association do not automatically override a shareholders’ agreement in every situation.
The Articles control the company’s formal constitutional procedures and bind the company and its members. The shareholders’ agreement creates private contractual obligations between its parties.
A company action may therefore be valid under the Articles but still breach the shareholders’ agreement. The safest approach is to ensure that both documents are consistent and reviewed together whenever the company’s ownership or management arrangements change.
