Fortis Healthcare Moves SC: What Forensic Audit Means for Corporate Compliance

Overview: Fortis Healthcare has moved the Supreme Court against the Delhi High Court’s order directing a forensic audit in the Daiichi Sankyo enforcement proceedings. The company disclosed the filing of its Special Leave Petition (SLP) on 16 September 2026.

For businesses, however, the development is relevant beyond the immediate court dispute. A major litigation involving a listed company can bring transaction records, statutory documentation, regulatory disclosures and corporate compliance processes under close scrutiny. The Fortis matter provides a useful example of why companies need reliable records and a clear compliance trail when significant transactions later become the subject of legal proceedings.

A major corporate dispute can quickly become a documentation and compliance issue — particularly when transactions, shareholdings and regulatory disclosures come under judicial scrutiny.

That is now playing out in the Fortis Healthcare matter. Fortis has filed a Special Leave Petition before the Supreme Court challenging the Delhi High Court’s 31 August 2026 order directing a forensic audit in the Daiichi Sankyo enforcement proceedings.

Fortis disclosed the SLP filing on 16 September 2026 under its Regulation 30 disclosure obligations. The immediate legal question is whether the High Court’s forensic-audit direction will stand.

But for other companies, the development raises a broader practical question: are your corporate records, transaction documents and regulatory disclosures strong enough to withstand scrutiny years after a transaction takes place?

That is where the corporate-compliance angle becomes important. A forensic audit may require the reconstruction of transactions from underlying agreements, share records, financial information and other supporting documents. Maintaining those records is therefore not merely an administrative exercise; it can become critical when a company’s transactions are subsequently examined by regulators, courts, auditors or other stakeholders.

Why This Fortis Development Matters to Companies

The Fortis case is a specific legal dispute, but the compliance lesson is much broader.

Companies regularly undertake transactions involving shares, investments, financing arrangements, pledges, related entities, board decisions and other significant corporate actions. At the time, the transaction may appear complete once the relevant approvals and filings have been made.

The difficulty can arise years later when a transaction needs to be reconstructed.

A company may then have to locate:

• board and shareholder resolutions;
• agreements and amendments;
• share-transfer records;
• registers and statutory filings;
• financial and banking records;
• correspondence supporting the transaction;
• records of pledges or encumbrances; and
• regulatory disclosures made at the relevant time.

The Fortis proceedings demonstrate why maintaining a proper documentary and statutory trail matters when significant transactions become subject to later scrutiny.

For listed companies, this also connects with the requirement to make appropriate disclosures of material events and developments under the applicable SEBI framework.

The Latest Fortis Development

Against this broader compliance backdrop, Fortis Healthcare has now taken its challenge to the Supreme Court.

The company’s regulatory disclosure states that it filed an SLP on 16 September 2026, challenging the Delhi High Court’s 31 August 2026 order in the proceedings concerning Daiichi Sankyo Company Ltd and others.

The filing was disclosed under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

The SLP is therefore the latest legal step taken by Fortis in the matter. It does not, by itself, mean that the High Court order has been stayed or overturned.

The Delhi High Court Order?

On 31 August 2026, the Delhi High Court directed a forensic audit in the enforcement proceedings. The Court appointed S Ramanand Aiyar & Co., Chartered Accountants, as the forensic auditor and directed that the exercise be completed within six months.

The audit concerns the reconstruction and examination of relevant transactions, including matters relating to Fortis shares, shareholding, pledges, encumbrances, transfers and sales.

Importantly, the High Court treated the forensic audit as an investigative exercise. The direction to conduct the audit does not, by itself, determine civil liability.

The Compliance Takeaway for Businesses

The immediate proceedings will now continue through the Supreme Court process. But companies need not wait for a dispute to arise before reviewing their documentation.

A sound corporate compliance framework should make it possible to trace a significant transaction from its commercial decision to board approval, execution, accounting, statutory records and regulatory disclosure.

This becomes particularly important for listed companies and businesses undertaking complex transactions, where several compliance functions may operate together.

Proper maintenance of statutory registers, board records, transaction documents and regulatory filings can provide the documentary trail needed when a transaction is later questioned or examined.

That is the wider corporate-compliance lesson from the Fortis development — compliance is not only about making a filing on time; it is also about being able to substantiate the transaction behind that filing.
