Evaluate the role of judicial oversight in balancing personal liberty (Article 21) with the imperatives of an ongoing criminal/money-laundering investigation.

Article 21 permits curtailment of liberty only by a fair, just and reasonable procedure [1], while the Prevention of Money-Laundering Act, 2002 arms the Enforcement Directorate (ED) with powers of search, attachment and arrest without prior judicial sanction [2]. Courts sit at this intersection, and their oversight has been largely effective in calibrating the two — though uneven in outcome.

Oversight protecting personal liberty

• Arrest as exception, not rule: the Arnesh Kumar (2014) guidelines require recorded reasons and notice of appearance before arrest in less-serious offences [3].
• Calibrated interim relief instead of binary outcomes: in the Salboni land-grab matter the Supreme Court stayed the arrest of Sumit Roy while directing him to appear for interrogation within fixed hours and cooperate — liberty preserved, investigation uninterrupted [4].
• Insistence on reasons for arrest being communicated to the accused checks arbitrary custody [3].

Oversight serving investigative imperatives

• In Vijay Madanlal Choudhary (2022), the Court upheld the ED's core PMLA powers — attachment, search and arrest — refusing to disable proceeds-of-crime probes [3].
• Courts equally spur reluctant agencies: in September 2026 the Supreme Court rebuked central agencies for "dragging their feet" against powerful persons while moving swiftly against ordinary accused, echoing the Calcutta High Court's earlier "despair" at the probe's intensity [4]. This makes oversight an instrument of Article 14 equality before law [1].

Limitations

• Relief is case-by-case and post-facto; oral strictures carry no enforceable remedy against selective vigour.
• The reverse burden of proof and stringent bail conditions under PMLA continue to weigh against the accused [2].
• Judicial review cannot substitute for internal agency accountability, which remains executive-controlled.

Judicial oversight thus succeeds as a corrective, not as a system of accountability. Strengthening it requires time-bound investigation, strict compliance with recorded-reasons safeguards, and transparent internal review within agencies — so that Articles 14 and 21 operate together, and the rigour of an investigation depends on the evidence, not the status of the accused.
