Parties and roles: Sita Soren is the appellant/applicant who initiated or carried the matter to the Supreme Court. Union of India is the respondent opposing the relief or defending the challenged action, decision, law or proceeding. The labels “plaintiff” and “defendant” are generally not used here because this is an appellate, special or Supreme Court proceeding. Sita Soren, then a Jharkhand MLA, was prosecuted for allegedly accepting money to vote for a candidate in a Rajya Sabha election. She invoked constitutional immunity for anything said or any vote given in the legislature. A 1998 majority in P.V. Narasimha Rao had protected legislators who accepted bribes and then actually spoke or voted as promised, creating an anomaly between bribe-takers who performed and those who did not. The Court reconsidered whether legislative freedom requires immunity from ordinary criminal law for bribery. Procedural setting: 2012: Sita Soren was accused of accepting a bribe connected with a Rajya Sabha election. | 2014: Jharkhand High Court rejected her claim of legislative privilege. | 2019: Supreme Court referred the immunity issue to a larger bench. | Sep 2023: Seven-judge reference ordered. | 04 Mar 2024: Judgment delivered unanimously. The central problem before the Court was do Articles 105(2) and 194(2) grant MPs or MLAs immunity from criminal prosecution for accepting bribes connected with a speech or vote? Should the majority ruling in P.V. Narasimha Rao be overruled? The controversy was considered in the framework of Prevention of Corruption Act, 1988; Indian Penal Code, 1860; Representation of the People Act, 1951, together with Constitution arts.105(2), 194(2), 32 and 141. The wider importance of the case lies in legislative privilege; functional necessity; probity in public life; rule of law; stare decisis and overruling.

Soren argued the constitutional text immunised a vote and acts closely connected with it, and stare decisis protected the earlier ruling. The Union and intervenors argued bribery is complete before the vote, is not essential to legislative functioning, and corrodes representative democracy rather than protecting debate. Competing positions in context: Sita Soren's position: as the appellant/applicant, Sita Soren sought the relief indicated by the questions of law and challenged the opposing action or interpretation. The claim was that the Court should apply the governing provisions consistently with Legislative privilege; functional necessity; probity in public life; rule of law; stare decisis and overruling. Union of India's position: as respondent, Union of India resisted that relief, defended the impugned measure or decision, or proposed a narrower interpretation of the Court's power and the applicable law. The Court therefore had to test these submissions against Prevention of Corruption Act, 1988; Indian Penal Code, 1860; Representation of the People Act, 1951 and Constitution arts.105(2), 194(2), 32 and 141, the record of the proceedings and binding precedent. This summary states the principal controversy in accessible language; the official judgment remains authoritative for counsel-specific submissions and paragraph references.

The Court unanimously held that legislative privilege does not immunise bribery. The offence is complete upon acceptance or agreement to accept an illegal gratification and is not part of the essential legislative function protected by the Constitution. P.V. Narasimha Rao was overruled to that extent. Privilege claims must satisfy a functional-necessity test tied to free deliberation, not personal impunity. Effect of the decision: the ruling explains or applies Legislative privilege; functional necessity; probity in public life; rule of law; stare decisis and overruling and binds the parties to the operative directions made in Criminal Appeal No. 451/2019. It also guides lower courts and public authorities on materially similar questions under Prevention of Corruption Act, 1988; Indian Penal Code, 1860; Representation of the People Act, 1951. Scope and caution: only the ratio decidendi and operative directions of the signed judgment are binding; summaries should not be treated as substitutes for the judgment, separate opinions, later review orders or subsequent precedent.
