Parties and roles: Lily Thomas is the petitioner who initiated or carried the matter to the Supreme Court. Union of India & Ors. 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 a constitutional writ proceeding. Sections 8(1)-(3) of the Representation of the People Act disqualified persons convicted of specified offences. Section 8(4), however, protected a sitting MP, MLA or MLC for three months and, if an appeal was filed, until the appeal ended. Thus a convicted incumbent could retain office while an identically situated non-member could not contest. Lily Thomas and Lok Prahari challenged Parliament's power to postpone a constitutional disqualification. The practical problem was prolonged continuation of convicted lawmakers merely because an appeal remained pending. Procedural and real-world context: 01 Sep 2005: Lily Thomas filed W.P.(C) 490/2005. | 17 Sep 2005: Registered. In simple terms, the Court had to resolve could Parliament enact Section 8(4) and defer disqualification only for sitting legislators? Did Articles 101(3)(a), 102(1)(e), 190(3)(a) and 191(1)(e) require the same and immediate consequence? Did Section 8(4) violate Article 14? The outcome mattered immediately because section 8(4) was ultra vires. Parliament may prescribe one set of disqualifications but cannot delay its operation for sitting members. Procedural setting: 01 Sep 2005: Lily Thomas filed W.P.(C) 490/2005. | 17 Sep 2005: Registered. | 2005-2013: Heard with Lok Prahari's W.P.(C) 231/2005. | 10 Jul 2013: Judgment pronounced; petitions allowed. The central problem before the Court was could Parliament enact Section 8(4) and defer disqualification only for sitting legislators? Did Articles 101(3)(a), 102(1)(e), 190(3)(a) and 191(1)(e) require the same and immediate consequence? Did Section 8(4) violate Article 14? The controversy was considered in the framework of Representation of the People Act, 1951, ss.7 and 8; Code of Criminal Procedure, 1973, ss.374, 389(1), 482, together with Constitution arts.14 (not decided), 32, 101(3)(a), 102(1)(e), 141, 142, 190(3)(a), 191(1)(e), 246, 248; List I Entry 97. The wider importance of the case lies in ultra vires; limited legislative competence; immediate vacancy; same disqualification standard; stay of conviction; prospective operation.

Petitioners: Articles 102 and 191 prescribe the same disqualifications for being chosen and for being a member; Articles 101 and 190 require immediate vacancy. A convicted member could seek a judicial stay of conviction. | Union: the protection preserved legislative stability, avoided changes of majority due to convictions later reversed, and only postponed—not altered—the disqualification. Competing positions in context: Lily Thomas's position: as the petitioner, Lily Thomas 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 Ultra vires; limited legislative competence; immediate vacancy; same disqualification standard; stay of conviction; prospective operation. Union of India & Ors.'s position: as respondent, Union of India & Ors. 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 Representation of the People Act, 1951, ss.7 and 8; Code of Criminal Procedure, 1973, ss.374, 389(1), 482 and Constitution arts.14 (not decided), 32, 101(3)(a), 102(1)(e), 141, 142, 190(3)(a), 191(1)(e), 246, 248; List I Entry 97, 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.

Section 8(4) was ultra vires. Parliament may prescribe one set of disqualifications but cannot delay its operation for sitting members. A seat becomes vacant when disqualification is incurred. Filing an appeal is insufficient, though an appellate court may stay the conviction itself. The Article 14 issue was expressly left undecided. Existing convictions with timely pending appeals were protected prospectively. Effect of the decision: the ruling explains or applies Ultra vires; limited legislative competence; immediate vacancy; same disqualification standard; stay of conviction; prospective operation and binds the parties to the operative directions made in W.P.(C) No. 490/2005; with W.P.(C) No. 231/2005. It also guides lower courts and public authorities on materially similar questions under Representation of the People Act, 1951, ss.7 and 8; Code of Criminal Procedure, 1973, ss.374, 389(1), 482. 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.
