A recent Court of Appeal ruling provides guidance on the circumstances in which unfair prejudice petitions can be used to address company losses.
Here, Senior Associate and experienced commercial litigator Matthew Moy explains what this means for shareholders.
In the case of Ntzegkoutanis v Kimionis [2023] EWCA Civ 1480, the Court of Appeal considered and clarified when it is appropriate for a shareholder bringing an unfair prejudice petition to also seek relief in favour of the company to which the petition relates — in addition to the relief that the shareholder seeks to claim for themselves.
The decision restates the law in this area and provides practical guidance on when to bring an unfair prejudice petition or a derivative action. It confirms that, in certain circumstances, shareholders may be able to achieve remedies in favour of their company without first having to overcome the stringent requirements of the derivative action regime.
Broadly speaking, shareholder claims arising from wrongful conduct fall into two main categories:
It is often the case that director misconduct has unfairly prejudiced shareholders and damaged the company — which raises the question of which procedure is more appropriate. An unfair prejudice petition is often preferred as it prioritises the shareholder’s individual interests. Conversely, a derivative action prioritises the company’s interests and is also considered to be more difficult to pursue — not least as it requires the court’s permission, which can be difficult to obtain.
Ntzegkoutanis v Kimionis concerned a company — Coinomi Limited — established by Mr Ntzegkoutanis and Mr Kimionis to develop and market a cryptocurrency wallet app.
Mr Ntzegkoutanis alleged that Mr Kimionis had excluded him from the management of Coinomi and also misappropriated the company’s assets and business.
He brought an unfair prejudice petition, seeking (among other things):
(i) That the misappropriated assets were held on a constructive trust for Coinomi.
(ii) An order that Mr Kimionis compensates Coinomi for losses caused by his conduct.
(iii) That Mr Kimionis sells his shares in Coinomi to Mr Ntzegkoutanis at a reduced value.
Mr Kimionis argued that (i) and (ii) sought relief on behalf of the company — rather than being relief for Mr Ntzegkoutanis as a shareholder of the company — and should be struck out. Mr Kimionis said the only way to pursue these remedies was to bring a derivative action on behalf of the company and obtain the court’s permission, which he alleged Mr Ntzegkoutanis was trying to bypass.
The High Court granted the strike out application on the basis that (i) and (ii) should have been brought as derivative claims. The judge referred to a decision (among others) of the Hong Kong Court of Final Appeal in Re Chime Corp Ltd (2004) 7 HKCFAR 546 (cited with approval in subsequent cases in numerous commonwealth jurisdictions, including England) in which it had been said that:
“It is a rare and exceptional case which the court will permit to proceed by way of an unfair prejudice petition when it would otherwise be brought by way of a derivative claim, because [to do so] subverts the regime … which imposes limitations on bringing derivative claims”.
Mr Ntzegkoutanis did not agree and appealed.
The Court of Appeal allowed the appeal and provided the following guidance:
Where — on the other hand — a petitioner seeks relief on behalf of the company and personal relief (which would not be available in a pure derivative claim, such as an order to purchase shares) and the petitioner is genuinely interested in obtaining that personal relief, striking out that petition would be inappropriate. Indeed, it might be impractical to insist on separate claims where, for example, the petitioner seeks both an order to buy or sell shares and an order for payment to the company for breach of duty.
The case contains welcome clarification of the law on the relationship between unfair prejudice petitions and derivative actions and confirms that the restrictive approach in Chime will not be followed. It explains that in certain circumstances, shareholders may be able to achieve remedies in favour of their company without first having to overcome the requirements of a derivative action.
However, such relief will not always be appropriate and petitioners will need to carefully consider how to frame their case. In particular, they will need to seek personal relief as a primary basis and avoid giving the impression that pursuing a remedy for the benefit of the company via an unfair prejudice petition is an improper attempt to seek relief in favour of the company through the back door.
