Parties and procedural roles: Radhika Agarwal and connected taxpayers or company officers were petitioners challenging coercive arrest powers exercised in tax investigations. The Union of India, tax departments and investigating officers were respondents defending statutory enforcement; business persons exposed to summons, search and arrest were the affected class. Supreme Court proceedings generally describe the sides as petitioner/appellant and respondent, or accused and prosecution, rather than plaintiff and defendant. In a suo motu case or constitutional reference, the Court or President initiates the proceeding and governments, authorities and affected stakeholders assist or respond.

Detailed story and problem statement: Radhika Agarwal and connected petitioners challenged arrest and summons powers exercised by Customs and GST officers, alleging coercion before tax adjudication. The Union defended the special fiscal-enforcement statutes and seriousness of evasion. The controversy became legally significant because the challenged action affected liberty, equality, institutional fairness, democratic accountability, property, family relations, professional rights or another protected interest. The side seeking relief said that the governing legal safeguards had not been honoured; the opposing side relied on its statutory power, the record and the need for workable administration or enforcement.

Procedural development: Multiple tax-arrest petitions accumulated from 2018; statutory amendments and precedent were examined; Constitution questions decided 27 February 2025. The matter reached the Supreme Court as W.P.(Crl.) No. 336/2018. Against this factual and procedural setting, the Court had to resolve: Are Customs/GST arrest provisions constitutional, and what safeguards govern summons, arrest, remand and recovery during investigation?

Petitioners sought CrPC-style safeguards, written grounds and protection from compelled payment. The Union argued revenue officers are not police and possess express arrest power.

Arguments supporting relief: The petitioner, appellant, accused or assisting party seeking intervention relied on Tax arrest powers; reasons to believe; procedural safeguards, the guarantees in Articles 20(3), 21 and 22, and the language and purpose of Customs Act, 1962 Sections 104 and 135; CGST Act, 2017 Sections 69 and 132; CrPC, 1973. That side argued that legal power is limited by fairness, relevant evidence, reasoned decision-making and proportionality. It asked the Court to examine the actual burden imposed and to grant effective relief rather than leave the alleged violation without a remedy.

Arguments opposing relief: The respondent government, regulator, prosecution, employer or private party relied on statutory competence, institutional autonomy, contractual or procedural rules, public interest, finality, administrative feasibility or the strength of the factual record, according to the nature of RADHIKA AGARWAL vs UNION OF INDIA. It urged restraint and argued that the challenged outcome fell within lawful discretion or that the requirements for extraordinary Supreme Court intervention were not met.

Judicial comparison: The bench tested these positions against precedent, statutory ingredients, the evidentiary and procedural record, and consequences for similarly situated people or institutions. The controlling questions were: Are Customs/GST arrest provisions constitutional, and what safeguards govern summons, arrest, remand and recovery during investigation?

The Court upheld statutory arrest powers but required objective reasons to believe, communication of grounds, CrPC-compatible safeguards and meaningful magistrate scrutiny. Threats, coercive recovery and routine handcuffing are impermissible; statements remain governed by constitutional protections.

Reasoning adopted by the Supreme Court: The Court interpreted Customs Act, 1962 Sections 104 and 135; CGST Act, 2017 Sections 69 and 132; CrPC, 1973 consistently with Articles 20(3), 21 and 22 and applied Tax arrest powers; reasons to believe; procedural safeguards. It examined jurisdiction and legislative or statutory authority, compliance with natural justice, relevance and sufficiency of the material, proportionality of the measure and the practical consequences of the proposed rule. Where appropriate, the Court distinguished merits from procedure, individual relief from general directions, and binding ratio from observations limited to the facts.

Result for the parties: The operative directions in W.P.(Crl.) No. 336/2018 determine RADHIKA AGARWAL vs UNION OF INDIA. The relief granted or refused, and any remand, bail condition, prospective operation, monitoring requirement, time limit, compensation rule or preservation of earlier proceedings, must be understood as part of the final outcome described above.

Broader legal significance: The ruling guides courts, legislatures, governments, investigators, regulators, employers or private parties confronting materially similar issues. Its scope remains subject to the qualifications expressed by the bench; where this summary and the signed decision differ, the official judgment and operative paragraphs are controlling.
