Before Adverse Action — The Legal Shield Around Preliminary Investigations

Nothing rattles a boardroom quite like an unexpected visit from investigators. The urge to demand “show me your authority” is strong, but courts in India, the UK, and the US broadly agree — investigations should not be stalled by requests for disclosure. In a recent case before the Delhi High Court, pursuant to the government’s order to the Serious Fraud Investigation Office (SFIO) to investigate a group of companies, a charitable company (Petitioner) that had allegedly transacted with those companies was directed to produce extensive financial records. 1 The court declined to compel disclosure of the government order for two reasons: 1) the SFIO’s notice already disclosed enough about the inquiry’s nature and purpose to negate any claim of opacity; and 2) the risk of undermining the broader investigation with parallel proceedings before another High Court. Non-interference as deference — Legal position in India The Delhi High Court’s ruling aligns with established Indian law: Courts generally avoid interfering with ongoing investigations or quash FIRs except in rare, exceptional cases. 2 Show-cause notices are similarly immune to judicial intervention, since they do not impose adverse consequences. 3 In January 2026, the Supreme Court reinforced this approach, refusing to halt a preliminary Competition Commission of India investigation and emphasising that probes must proceed in accordance with law. 4 Read holistically, these decisions establish a clear judicial pattern — unless an investigation results in adverse action affecting rights, preliminary steps remain shielded from early court intervention. Is this a peculiarly Indian instinct? A similar calculus operates in the UK and the US. In England, an oil and gas company sought judicial review of the Serious Fraud Office’s (SFO) refusal to disclose material relating to an ongoing investigation. The High Court found no basis to compel disclosure, noting that even the applicable European Union (EU) Directive contemplates disclosure only “without prejudicing the course of ongoing investigations”. 5 It has further been held that only a wholly exceptional case could justify judicial review of the SFO’s decision to investigate, given that such discretion is broader than the discretion whether to prosecute. 6 The closest American analogue — the federal grand jury subpoena— is, if anything, more restrictive. A recipient generally has no right to know the basis for suspicion, before complying. A subpoena issued through normal channels is presumed reasonable, and a motion to quash on relevancy grounds must fail unless there is no reasonable possibility that the material sought is relevant to the investigation’s general subject. 7 The one narrow concession is that where a recipient does not know even the general subject-matter, a court may require the government to reveal it. That still falls well short of disclosing the grounds for suspicion or any equivalent of an authorising order. The boundary is the real story None of the three jurisdictions give a party under investigation an enforceable right to the investigator’s file. The value of comparison lies not in that shared refusal, but in what each system treats as an exception. Indian Courts may intervene where an FIR or notice is issued without jurisdiction, is wholly illegal, or is manifestly mala fide . English Courts may intervene where an investigator’s conduct is genuinely irrational or in bad faith. American Courts may quash a subpoena where the government cannot show a legitimate purpose, or where compliance would be unreasonable or oppressive. The consistent thread is not blanket immunity for investigators, but a high evidentiary bar for anyone seeking to interrupt an investigation before it produces an adverse consequence. What this means in practice The lesson is straightforward — do not expect a court to intervene at the preliminary stage, because in ordinary cases it will not. Three habits follow: 1.
