Section 994 of the Companies Act 2006 allows shareholders to ask the court to intervene when the affairs of a company are conducted in a way that is unfairly prejudicial to their interests.
Although the statutory wording is relatively short, the meaning of “unfair prejudice” has been shaped by decades of case law. Courts have developed principles explaining when conduct crosses the line from a commercial disagreement into something that justifies court intervention.
Understanding these cases is important for shareholders and directors involved in disputes. They show how courts interpret fairness, what evidence is persuasive, and when a petition is likely to succeed.
Why is case law important in unfair prejudice claims?
Section 994 provides the legal framework, but it gives the court broad discretion. As a result, judges rely heavily on previous decisions to determine whether conduct is unfairly prejudicial.
Case law helps answer several key questions.
First, it clarifies what conduct counts as unfair. Not every disagreement between shareholders will qualify.
Second, it explains how courts balance strict legal rights against equitable principles such as good faith and legitimate expectations.
Third, it guides the court when deciding what remedy is appropriate, particularly in relation to share buy-outs.
For these reasons, many unfair prejudice petitions focus heavily on how previous decisions have approached similar disputes.
What did O’Neill v Phillips establish about fairness in shareholder disputes?
One of the most influential decisions in unfair prejudice law is O’Neill v Phillips, decided by the House of Lords.
The case concerned a dispute between two shareholders in an insurance brokerage business. One shareholder alleged that the majority had unfairly withdrawn a promise to make him an equal partner.
The court emphasised that unfairness must be grounded in legal rights or equitable principles. A shareholder cannot rely simply on a subjective sense of injustice.
Lord Hoffmann explained that fairness is usually assessed by reference to:
- the company’s constitution
- any shareholders’ agreements
- equitable principles governing the relationship between the parties.
The concept of legitimate expectations plays an important role. In many private companies, particularly those operating as quasi-partnerships, shareholders expect to participate in management or decision making. If that expectation forms part of the underlying relationship, excluding a shareholder from management may be unfair.
However, the court also stressed that not every disappointment amounts to unfair prejudice. There must be a clear departure from the understanding on which the parties agreed to conduct business together.
How have courts applied the unfair prejudice test in later cases?
Since O’Neill v Phillips, courts have applied the principles to a wide range of shareholder disputes.
Several patterns appear frequently in the case law.
1. Exclusion from management
In small companies where shareholders expected to take part in running the business, removing a shareholder-director from management may constitute unfair prejudice.
Courts often examine whether the company functioned like a partnership, where mutual trust and participation were central to the relationship.
2. Diversion of company business
Courts have also intervened where directors or majority shareholders divert business opportunities or assets away from the company for personal benefit.
This may involve transferring contracts, intellectual property or clients to another entity controlled by the majority.
3. Excessive remuneration or extraction of value
Another recurring issue is where the majority extracts profits through salaries, bonuses or related-party arrangements rather than paying dividends. This can disadvantage minority shareholders who rely on dividends as their return on investment.
4. Share dilution and manipulation of control
Issuing shares to dilute the minority’s voting power may also amount to unfair prejudice if done for an improper purpose.
Courts will consider whether the share issue genuinely served the interests of the company or was primarily intended to entrench control.
These examples demonstrate that unfair prejudice claims often arise from a combination of financial harm and the breakdown of trust between shareholders.
What does the THG v Zedra Supreme Court decision mean for shareholders?
A significant recent development in this area came with the Supreme Court decision in THG plc v Zedra Trust Company (Jersey) Ltd, handed down in February 2026.
The case addressed whether unfair prejudice petitions are subject to the statutory limitation periods contained in the Limitation Act 1980.
The Supreme Court confirmed that those limitation periods do not apply to petitions under section 994.
This means that shareholders are not automatically prevented from bringing a petition simply because several years have passed since the conduct occurred.
However, the court also emphasised that delay remains relevant. Because the court has wide discretion over remedies, it may take delay into account when deciding whether relief should be granted.
For example, delay may influence:
- whether the court considers a remedy fair
- the appropriate valuation date for a share buy-out
- the availability of evidence.
The decision therefore provides flexibility but does not remove the practical risks of waiting too long before seeking legal advice.
What lessons do these cases provide for shareholders considering a petition?
The case law surrounding unfair prejudice petitions highlights several practical points.
- First, not every shareholder disagreement justifies court intervention. The conduct must be both unfair and prejudicial.
- Second, the courts often examine the nature of the relationship between shareholders, particularly in smaller private companies. Where a business operates as a quasi-partnership, expectations about management participation may carry significant weight.
- Third, documentary evidence is often decisive. Shareholder agreements, company accounts, board minutes and communications frequently determine how the court interprets events.
- Finally, although there is no statutory limitation period, delay can still weaken a claim. Obtaining early legal advice can help shareholders understand their options and avoid strategic disadvantages.
