Shareholder Rule Gets Short Shrift


Derived from 19th century case law, the general school of thought has been that a company cannot assert privilege against its own shareholder, save in relation to documents that came into existence for the purpose of hostile litigation against that shareholder (the so-called “Shareholder Rule”).

In a judgment dated 27 November 2024, Mr Justice Picken (sitting in the English High Court) delivered a landmark ruling decisively rejecting the ‘Shareholder Rule’ on all bases (the Judgment). The Judgment represents a long awaited, significant, departure from what was considered to be a long-standing legal principle and seeks to align the concept of privilege under English law with contemporary corporate realities. The Judgment also clarifies the concept and scope of Joint Interest Privilege as a mater of English law.

Background

The Judgment was given in relation to ongoing group litigation brought by Aabar Holdings S.À.R.L (Aabar) and other shareholders against Glencore PLC (Glencore) involving claims under s. 90 and 90A of the Financial Services and Markets Act 2000 in relation to alleged (but in some cases admitted) misconduct by companies within the Glencore group. Within the context of the proceedings, a dispute arose as to whether Glencore would be entitled to assert privilege against the shareholder litigants.

Aabar argued that, during the relevant period, it was the indirect shareholder of Glencore (via its shareholding in another company which was the ultimate beneficial owner of Glencore via its holding of intermediated securities) and that, by virtue of the Shareholder Rule, Glencore was not entitled to withhold documents from it on the basis of privilege.

The Shareholder Rule

The Shareholder Rule was historically rooted in the notion that the shareholders of a company had a proprietary interest in the company’s assets, including the legal advice it received. However, Aabar’s counsel argued that the underlying rationale of the Shareholder Rule (i.e. the proprietary interest just described) had “morphed” into an emanation of joint interest privilege and that Aabar, as shareholder, had a joint interest with its company, Glencore, which meant that it was entitled to receive copies of documents which would have otherwise ordinarily been protected by privilege.

The End of the Shareholder Rule?

The Court dismissed Aabar’s argument and ultimately rejected the Shareholder Rule:

Given its finding, there were certain other issues which the Court had been asked to determine which fell away because they were based on the Shareholder Rules being found to exist. Notwithstanding this, the Court went on to consider such issues on the premise that the Shareholder Rule did in fact exist in some form or another. In this scenario, it found the following:

Significance of the Judgment for Shareholder and Companies

The Judgment, as it presently stands, means that a shareholder cannot rely on the so-called Shareholder Rule, or simply assert joint interest privilege, in order to obtain disclosure of otherwise privileged information held by the company. This is a far-reaching consequence for any proceedings concerning disputes between a company and its shareholder(s), such as unfair prejudice or derivative actions. As noted above, rather than there being some blanket rule, the Court favoured a case-by-case approach, in which the relevant facts must demonstrate that the company and shareholder had a mutually beneficial and joint interest in obtaining the relevant advice or documents of which disclosure by the shareholder is sought. From the shareholder’s perspective, if they want a better chance of being able to see privileged material belonging to the company, then they may seek to agree with the company ahead of time that the relevant advice is being sought on a joint basis. Conversely, directors of a company can now breathe a little easier, knowing that legally privileged documents cannot be obtained by a shareholder simply as of right via the back door of the Shareholder Rule.

Given the significance of the Judgment, we anticipate that it may be appealed by Aabar. Equally there are other cases where the existence of otherwise of the Shareholder Rule also features and it will be interesting to see how the courts in those other cases grapple with the issue and whether those decisions are appealed. So watch this space….
