NMC Health PLC v Ernst & Young LLP (Re Disclosure)

Factual and Procedural Background

This opinion concerns a resumed hearing following an initial hearing on 1st November, where insufficient time was available to address a particular matter fully. The matter relates to a category of documents described as "investigative documents," generated by the administrators of Company A. The hearing addresses issues concerning the disclosure and privilege of these documents in the context of ongoing litigation involving allegations of fraud and claims against an auditor.

The procedural context includes a previous hearing before Judge Bright on 15th April of the same year, which considered a narrower category of administration documents. The current hearing revisits certain issues with further developed submissions from counsel representing the parties.

Legal Issues Presented

1. Whether the Defendant is precluded from revisiting issues relating to investigative documents due to a prior ruling by Judge Bright (the Henderson v Henderson abuse of process principle).
2. The relevance of the investigative documents generated by the administrators.
3. Whether the Claimant is entitled to assert litigation privilege over certain investigative documents, specifically interview transcripts and witness statements.

Arguments of the Parties

Appellant's Arguments

• The Defendant contends that the Henderson v Henderson principle precludes the Claimant from raising points about investigative documents that were previously addressed.
• The Defendant disputes the relevance of the broader category of investigative documents beyond contemporaneous administration documents.
• Litigation privilege should not apply to all investigative documents, particularly where the dominant purpose was not the conduct of litigation.
• Correspondence from the administrators' solicitors shortly after appointment suggests no dominant purpose of litigation at that time, undermining the Claimant's privilege claim.

Appellee's Arguments

• The Claimant asserts that the Henderson v Henderson principle does not bar revisiting issues concerning a wider category of investigative documents beyond the narrower category previously considered.
• The Claimant accepts the relevance of interview transcripts and witness statements but argues other investigative documents are irrelevant and should not be disclosed.
• Litigation privilege applies to the interview transcripts and witness statements, as these were created with the dominant purpose of litigation, specifically claims against the auditor and others.
• Evidence from a senior solicitor and administrators supports that the dominant purpose of the interviews and witness statements was for litigation, despite initial correspondence indicating investigations rather than active claims.
• Analogies are drawn with Hong Kong case law where similar investigative documents were held privileged due to their dominant purpose related to litigation.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
Henderson v Henderson	Prevents re-litigation of issues already decided (abuse of process).	The court acknowledged the principle but did not base its decision on it, noting the prior ruling concerned a narrower category of documents.
China Forestry Holdings Co Limited (In Official Liquidation) and Others v KPMG [2020] HKCFI 2614	Limitations on disclosure of investigative documents in fraud-related auditor negligence claims, focusing on relevance and probative value.	The court adopted the principle that post-event investigative documents with questionable probative value are irrelevant and should not be disclosed; this principle was applied analogously.
Waugh v British Railways Board [1980] AC 521	Definition of litigation privilege: documents created with dominant purpose of litigation are privileged.	Litigation privilege was applied to the interview transcripts and witness statements based on this definition.
Starbev v Interbrew Central European Holding BV [2013] EWHC 4038 (Comm)	Clarifies that litigation privilege requires dominant purpose of enabling legal advice or evidence gathering for contemplated litigation.	Supported the court's analysis of the dominant purpose test for litigation privilege in this case.
Akai Holdings Limited In Compulsory Liquidation v Ernst & Young (2008) HKCFA	Confirmed that liquidators’ interviews and notes are privileged if created for dominant purpose of litigation reasonably in prospect.	The court relied on this case to support the assertion of litigation privilege over interviews and witness statements.
West London Pipeline and Storage Limited v Total UK Ltd [2008] EWHC 1729 (Comm)	Requirement for specificity in affidavits claiming privilege to show dominant purpose.	The court found the evidence sufficient to satisfy the dominant purpose test for litigation privilege.

Court's Reasoning and Analysis

The court first considered whether the Henderson v Henderson abuse of process principle barred revisiting the issue of investigative documents. The court found no need to base its decision on this principle, noting the prior ruling dealt with a narrower category of documents and that the current wider category was distinct.

Turning to relevance, the court distinguished between contemporaneous administration documents, which had been disclosed and accepted as relevant, and post-event investigative documents generated by the administrators, which were not relevant. The court found persuasive the reasoning of the Hong Kong court in China Forestry, which held that post-event investigative documents with questionable probative value should not be disclosed, especially where the trial was not about the fraud itself but about related claims.

The court acknowledged the acceptance of the relevance of interviews and witness statements but rejected the relevance of the wider category of investigative documents, describing attempts to find relevant material within that category as "needle in the haystack" and speculative.

Regarding litigation privilege, the court applied the established legal test that privilege attaches to documents created with the dominant purpose of litigation reasonably in prospect. The court reviewed detailed witness evidence from the Claimant’s solicitor confirming that the interviews and witness statements were created with the dominant purpose of litigation. The court also considered correspondence from the early stages of administration, which suggested no active claims were being pursued at that time, but concluded that this did not undermine the assertion of privilege since the dominant purpose was to enable litigation broadly, not necessarily only against the Defendant.

The court relied on analogous authority from the Hong Kong Court of Final Appeal in Akai Holdings, which recognized that liquidators’ investigative documents could be privileged if created for the dominant purpose of litigation. The court also found the supporting affidavits sufficiently detailed to satisfy the requirement for specificity in claims of privilege.

In sum, the court held that the investigative documents beyond the interviews and witness statements were not relevant and thus not disclosable, while the interviews and witness statements were relevant and protected by litigation privilege.

Holding and Implications

DISPOSED OF

The court ruled that the broader category of investigative documents generated post-event by the administrators are not relevant and therefore need not be disclosed. The court did not need to decide the abuse of process point or privilege in relation to those documents. However, the court found that the interview transcripts and witness statements are relevant and that litigation privilege properly attaches to them, protecting them from disclosure.

The direct effect of this decision is that the Claimant is not required to disclose the wider investigative documents but must maintain privilege over the interviews and witness statements. No new precedent was established; rather, the court applied established principles to the facts before it.
