Discuss the significance of the Supreme Court's ruling in *Lalita Kumari v. State of Uttar Pradesh* (2013) in balancing citizens' rights with the need for effective investigation of economic offences.

The Constitution Bench in Lalita Kumari (2013) settled a long-standing conflict: registration of an FIR under Section 154 CrPC is mandatory where information discloses a cognizable offence, but a preliminary inquiry is permissible where it does not — expressly including corruption and commercial offences [1]. The ruling is thus a calibrated compromise between liberty and law enforcement, not a concession to either.

Protecting citizens' rights

• Economic-offence allegations are often documentary and contested; an instant FIR can destroy reputation and livelihood, aspects of Article 21, before any evidence is tested [1].
• The consequences attach early: under the PMLA the ED can provisionally attach property and the accused bears a reverse burden of proof (Section 24) — provisions upheld in Vijay Madanlal Choudhary (2022) but now referred for reconsideration [2].
• The inquiry is a filter against frivolous and motivated complaints, the risk being highest where the accused is a political figure.

Preserving effective investigation

• The scope of the inquiry is narrow — only to ascertain whether a cognizable offence exists, not to verify the truth of the allegation; once disclosed, FIR registration is compulsory [1].
• It must be time-bound, with reasons and delay recorded in the General Diary, creating an audit trail against both inaction and shielding of the influential [1].
• It enables states to act responsibly on material shared by central agencies under Section 66(2), PMLA [3] — as in Kerala's 2026 order for a preliminary probe in the CMRL–Exalogic matter, where an inquiry, not an FIR, was directed [4].

Enduring influence

• The principle has been statutorily codified in Section 173(3), BNSS, 2023, permitting a prima facie enquiry within fourteen days in specified cognizable cases [5].

Lalita Kumari therefore converted police discretion into a structured, reviewable duty. Its promise is realised only when inquiries are genuinely time-bound and their outcome placed on record; open-ended files invite the very misuse the Court sought to prevent. Procedural fairness, the judgment affirms, strengthens rather than weakens the fight against economic crime.
