The Supreme Court on October 6 reserved judgment on a crucial question of election law: whether the Election Commission of India is bound to hold a bye-election when the remainder of a legislative term, after deducting the six-month statutory window, falls below one year. A three-judge bench consisting of Justice Vikram Nath, Justice Augustine George Masih, and Justice Sandeep Mehta heard extensive submissions from all sides before deferring its verdict. The case arose from a Bombay High Court order that directed the Election Commission to conduct a bye-election for the Pune Lok Sabha constituency, a direction the Commission challenged.

The Core Dispute

At the heart of the matter is Section 151A of the Representation of the People Act, 1951 , which mandates that a bye-election to fill a casual vacancy in Parliament or a state legislature "shall be held within a period of six months from the date of the occurrence of the vacancy." The provision contains two exceptions: it does not apply if the remainder of the term of the member in relation to the vacancy is less than one year, or if the Election Commission, in consultation with the central government, certifies that it is difficult to hold the bye-election within the prescribed period.

The critical interpretive question is from what point the one-year period under the first exception is to be calculated. The Bombay High Court held that the relevant date is the date on which the vacancy occurs. The Election Commission has contended that the six-month period available to it for conducting the bye-election must be accounted for before determining whether the one-year exception applies.

Background: The Pune Vacancy and the High Court Order

The dispute originated from the death of sitting Pune MP Girish Bapat on March 29, 2023. The term of the 17th Lok Sabha was due to expire on June 16, 2024, leaving more than 14 months from the date of vacancy. The Election Commission declined to hold a bye-election, issuing a certificate under Section 151A asserting that it was difficult to conduct the election because of its engagement with preparations for the 2024 general elections and the fact that any candidate elected would serve only a limited tenure.

Pune resident and voter Sughosh Joshi challenged this decision before the Bombay High Court, arguing that Section 151A required the vacancy to be filled within six months and that the constituency could not be left unrepresented. On December 13, 2023, the High Court directed the Election Commission to conduct the bye-election.

The High Court ruled that the one-year exception did not apply because the vacancy had occurred on March 29, 2023 , and more than one year of the Lok Sabha's term remained on that date. It held that "the date of occurrence of the vacancy was the only relevant date for determining whether the remainder of the term was less than one year." The court further observed that the Election Commission could not adopt a "sliding scale" approach, allowing months to pass after a vacancy and then relying on the remaining period as a reason not to conduct the election. It also rejected the argument that administrative inconvenience or preoccupation with other elections constituted "difficulty" under the second exception.

The Supreme Court stayed the High Court's direction in January 2024, noting that the interpretation of Section 151A required careful consideration. The factual question concerning the Pune seat is no longer a live issue, as the 17th Lok Sabha completed its term on June 16, 2024, and a new Lok Sabha has since been elected.

Parties' Positions

During the proceedings before the Supreme Court, the Election Commission maintained that the one-year period should be considered after accounting for the six-month period available for conducting the bye-election. This approach, it argued, would give effect to the statutory timeline while preventing bye-elections for short residual terms.

The respondents, including the original petitioner Sughosh Joshi, challenged this interpretation. They emphasised the statutory right of a constituency to representation and argued that the Election Commission could not effectively extend the six-month deadline by redefining the starting point of the one-year exception. They also pointed to what they said was the Commission's inconsistent application of Section 151A across different vacancies.

The Union of India, represented by Solicitor General Tushar Mehta and Additional Solicitor General K.M. Nataraj, also made submissions on the legal question.

Next Steps

After hearing arguments from senior counsel Dama Seshadri Naidu, Kaushik Laik, and Uday Bhatia for the petitioners, and Ritin Rai for the respondents, along with the law officers, the bench reserved judgment. The court permitted the parties to file fresh detailed written submissions within a week.

The Supreme Court's eventual ruling will settle the interpretation of Section 151A and determine the circumstances under which the Election Commission can lawfully decline to hold a bye-election when a legislative seat falls vacant. The decision will have practical consequences for the representation of constituencies across the country and the Commission's discretion in scheduling elections.
