Supreme Court seeks Election Commission's records on changes to Form 6
Must knowGS-2
A three-judge Bench headed by Chief Justice Surya Kant on Monday issued notices to the Election Commission, Chief Election Commissioner Gyanesh Kumar, the two Election Commissioners and senior Commission officials, seeking the "complete original and primary records" behind the changes made to Form 6, the application form through which new voters enrol on the electoral roll. The Bench was hearing a plea that alleged a "modified" Form 6 was used during the Special Intensive Revision (SIR) of the rolls and sought the ongoing exercise be declared illegal.
The Chief Justice said the court would examine who modified the form once the Commission's report arrived, and warned that any decision taken without unanimity or majority "will have to go": "We can always annul any decision," he said. Justice Joymalya Bagchi added that the court could injunct decisions taken neither unanimously nor by majority. In a separate remark, the CJI clarified that the Supreme Court had not approved "any" of the modifications to Form 6.
The controversy traces to a September 23 investigation which reported that the two Election Commissioners had objected on record, calling the changes "illegal and unauthorised", including the online form on the ECINet portal asking applicants whether they, their parents or grandparents figured on the electoral roll of the last SIR. It has since become a political flashpoint: Rahul Gandhi posted that the form was changed illegally to help the ruling party, while BJP spokesperson Sambit Patra accused him of "spreading lies and confusion", arguing the court had issued notices, not a verdict.
Why it matters: Form 6 is the statutory doorway to the franchise for new voters, so altering it implicates Article 326's guarantee of universal adult suffrage and the Commission's powers under Article 324. Prelims: know the forms, 6 (new enrolment), 7 (objection or deletion), 8 (change of residence or corrections), and that the ECI is a multi-member body expected to act collectively. Mains: judicial review of election management, the institutional independence of the Commission, and the line between administrative convenience and the duty not to exclude eligible citizens.

Bombay High Court: what is the purpose of SIR if citizens are being removed?
Must knowGS-2
Hearing a petition in which six members of one family were struck off the rolls after their Form 8 applications for a change of address were rejected, the High Court of Bombay at Goa on Monday questioned the very purpose of the Special Intensive Revision if citizens were being deleted from the voters' list. "If citizens are excluded, what will we do with SIR?" a Division Bench asked, describing the voter's position as a "Catch-22": the Commission cannot refuse to hear an applicant who reports a shift of residence.
The human cost is visible in West Bengal, where nearly 19,000 voters in Nandigram and Rejinagar will miss Tuesday's byelections because their appeals are pending before Appellate Tribunals, part of 38.31 lakh voters across the state whose cases are stuck in the system. The tribunals have decided only about 1.26 lakh appeals, roughly three per cent; the Calcutta High Court had observed in July that clearing the backlog at the current pace would take 21 years. In Rejinagar, only 4 of 12,452 appeals have been decided; in Nandigram, 89 of 6,443.
Elsewhere, the Telangana Chief Electoral Officer ordered action against the misuse of Form 7 to delete eligible voters, and fresh petitions in the Supreme Court and the Bombay High Court have questioned the functioning of CEC Gyanesh Kumar, one seeking an SIT investigation and his removal, citing the on-record objections of the two Election Commissioners. The petitioners argue that Article 324(1) vests the superintendence, direction and control of elections in the Commission as a body, not in an individual Chief Election Commissioner.
Why it matters: the SIR, the first full-scale intensive revision in over two decades, is now being litigated on multiple fronts at once. Prelims: today's byelections cover six seats, Nandigram and Rejinagar (West Bengal), Madurantakam and Dharapuram (Tamil Nadu), Thattanchavady (Puducherry) and Nagaon (Assam). Mains: due process in mass revision exercises, the right to vote under Article 326 and the Representation of the People Act, and the institutional design of a multi-member Election Commission.

Bangladesh: Hasina's presence in India the "principal challenge" to PM's visit
Must knowGS-2
Bangladesh's State Minister for Foreign Affairs Humaiyun Kobir said on Monday that the "principal challenge" in planning Prime Minister Tarique Rahman's visit to India is the activities of deposed premier Sheikh Hasina and her team, who are based in India. Speaking on the sidelines of the Bay of Bengal Conversation organised by Dhaka's Centre for Governance Studies, he said New Delhi had to appreciate the "challenges of a newly elected government" and that the exiled leaders' activities "will not help India".
Kobir also stressed Bangladesh's "strategic autonomy", and said the visit, though bilateral, faced challenges that dialogue could overcome. Hasina has been in India since the fall of her government in August 2024, and her continued presence remains the sharpest irritant in the bilateral relationship.
Why it matters: the episode captures how a domestic political transition in the neighbourhood resets India's equations, from hospitality for a former head of government to working ties with her successor. Prelims, the India-Bangladesh land boundary settlement, Teesta waters, cross-border connectivity. Mains, managing ties across regime change in the neighbourhood, and the tension between "strategic autonomy" as Dhaka frames it and India's interest in a stable eastern flank.

One Nation, One Election: Supreme Court cancels proposed meeting with House panel
GS-2
The chairman of the Joint Committee of Parliament on the One Nation, One Election Bills, P P Chaudhary, said on Monday that the Supreme Court had on September 22 confirmed a meeting with committee members at 4.30 pm on October 6, but cancelled it on October 1 after objections were raised. The panel was to make a "local study visit" to the court, including an informal discussion with the Chief Justice and other judges on simultaneous elections.
The controversy broke after Rajya Sabha MP Kapil Sibal called the proposed meeting "unconstitutional" at an October 1 press conference, arguing that the Bills under the committee's deliberation could one day come before the court for adjudication, making any pre-decisional interaction between the legislature's panel and the judiciary improper.
Why it matters: the episode spotlights separation-of-powers concerns inside the ONOE debate. Simultaneous elections would need constitutional amendments, touching provisions on the duration of the Lok Sabha and the assemblies among others, and have already faced the basic-structure question of federalism. Prelims: a Joint Committee of Parliament examines a Bill with members drawn from both Houses. Mains: the propriety of informal legislature-judiciary engagement on live legislative proposals, and the federalism critique of simultaneous polls.

Three new Supreme Court judges, including the court's second woman Justice
GS-2 · Prelims
President Droupadi Murmu on Monday appointed three High Court Chief Justices as judges of the Supreme Court: Justices Sunita Agarwal (Gujarat), Devendra Kumar Upadhyaya (Delhi) and Aparesh Kumar Singh (Telangana). The appointments, announced by Law Minister Arjun Ram Meghwal, follow the collegium's recommendation on September 28.
Justice Sunita Agarwal becomes the court's second sitting woman judge, alongside Justice B V Nagarathna. Both Justices Agarwal and Upadhyaya have the Allahabad High Court as their parent High Court; Justice Singh's parent High Court is Jharkhand. Once the three take oath, expected on Tuesday, the court's working strength rises from 34 to 37.
Why it matters: these are the second set of appointments since Parliament raised the court's sanctioned strength from 34 to 38, including the CJI, through the Supreme Court (Number of Judges) Amendment Act, 2026. Prelims: Supreme Court judges are appointed by the President on the collegium's recommendation under Article 124, and Parliament fixes the number of judges by law. Mains: the collegium system's opacity versus executive primacy debate, and the representation of women in the higher judiciary, with Justice Nagarathna in line to become India's first woman CJI in 2027.
Great Nicobar project: Supreme Court declines stay; tribal culture a fundamental right
GS-2 · GS-3
The Supreme Court on Monday refused the Union government's plea to stay proceedings before the Calcutta High Court in a petition challenging the Great Nicobar Island Project. A three-judge Bench headed by the Chief Justice instead asked the High Court to hear and decide the matter without delay. The petition, filed by former Union Environment Secretary Meena Gupta, argues the project threatens the island's fragile ecosystem and violates the Forest Rights Act, 2006.
The Bench observed that "preservation of culture is a constitutionally protected fundamental right". The Centre, represented by the Attorney General and the Additional Solicitor General, countered that the project, worth over Rs 72,000 crore and centred on a container transhipment terminal, was of "immense" national importance and strategic value, and that there would be "no loss of habitation" for the indigenous tribal population.
Why it matters: the project sits at the fault line between strategic infrastructure and the rights of some of India's most vulnerable tribal communities, including the Shompen, a Particularly Vulnerable Tribal Group. Prelims, Great Nicobar hosts India's southernmost point (Indira Point); PVTGs; the Forest Rights Act, 2006. Mains, development versus indigenous rights, how far "strategic necessity" can stretch against constitutional protections, and what safeguarding tribal culture demands of project clearances.

Pakistan, Saudi Arabia and Turkiye agree on rapid troop deployment in the Kingdom
GS-2
At an emergency meeting of the "Mecca Defence Alliance" in Riyadh on Monday, Pakistan, Saudi Arabia and Turkiye agreed to move immediately to implement their collective-defence commitments, including the "rapid deployment" of agreed military forces and capabilities in Saudi Arabia, under "approved arrangements" and national laws. The decision was announced in a joint statement shared by Pakistan's foreign ministry.
The meeting reaffirmed the three countries' solidarity "in confronting the heinous attacks against the Kingdom and the holy sites". It follows a Saudi-led coalition statement that the Iran-aligned Houthis attacked a power distribution station in Medina on October 1.
Why it matters: the pact formalises a Pakistan-Saudi-Turkiye security axis in West Asia at a moment of sharpened Iran-Saudi and Houthi tensions. For India, the stakes run through energy security, the safety of its large diaspora in the Gulf, and its careful balancing of ties with Iran, Saudi Arabia and Israel. Prelims, Medina (Saudi Arabia); the Houthis (Ansar Allah) of Yemen; the Bab el-Mandeb chokepoint. Mains, what a collective-defence arrangement in West Asia means for India's extended-neighbourhood policy.

Exercise Mountain Guardian: India-UAE joint drill begins in Uttarakhand
GS-2
The joint military exercise "Mountain Guardian" between India and the UAE began on Monday at the Foreign Training Node, Chaubatia, in Uttarakhand. Ninety-two personnel, equally drawn from both armies, are taking part, with the Indian contingent from a Bhairav Battalion and the UAE contingent from a Mountain Infantry Battalion. Women officers and combatants from both sides are participating in specialist roles.
Running from October 5 to 18, the exercise focuses on mountain warfare and aims to build interoperability, mutual understanding and cooperation between the two armies.
Why it matters: defence cooperation is now a full pillar of the India-UAE relationship, with the two militaries already exercising together across services, including the Desert Cyclone army exercise. Prelims, Chaubatia (Uttarakhand); mountain-warfare training nodes. Mains, how joint exercises convert a transactional energy-and-diaspora relationship into a strategic partnership.

Kaliningrad: Russia's Baltic exclave becomes a new flashpoint
GS-2
Russian President Vladimir Putin warned on October 1 at the Valdai Discussion Club that if Russia faced a direct attack, "the question of the Russian Federation deploying all types of weapons at our country's disposal will inevitably and immediately be on the agenda", remarks made with reference to Kaliningrad. He insisted Moscow had no plans to attack anyone, "neither in 2029, not in 2030, not even in 2050", but said Russia would be compelled to respond to aggression.
Kaliningrad, Russia's exclave on the Baltic Sea wedged between Poland and Lithuania, has been in the spotlight as NATO countries step up military activity in the Baltic Sea and around the exclave.
Why it matters: the exclave sits at one end of the narrow Suwalki corridor, NATO's vulnerable land link between the Baltic states and the rest of the alliance, which is why Kaliningrad doubles as both tripwire and pressure point. Prelims, map work: Kaliningrad Oblast between Poland and Lithuania on the Baltic; NATO's eastern flank. Mains, escalation dynamics in the Baltic theatre and how exclaves become leverage in great-power rivalry.

IMF clears $345 million more for Sri Lanka
GS-2 · GS-3
The IMF said on Monday it had reached a preliminary agreement with Sri Lanka that unlocks about $345 million from the country's $2.9-billion bailout programme. The lender noted 11 consecutive quarters of expansion after the economy contracted 7.3% in 2022, but warned that higher energy prices, El Nino and the West Asia conflict could threaten the recovery.
The agreement is the latest review milestone in Sri Lanka's climb out of its 2022 sovereign default on $46 billion of external debt, for which it secured a four-year, $2.9-billion IMF package in 2023.
Why it matters: Sri Lanka's stabilisation is the neighbourhood's textbook case of an IMF Extended Fund Facility, debt restructuring, fiscal consolidation and reform conditionality. Prelims, the 2022 default, the EFF window, Colombo's creditor negotiations. Mains, debt sustainability in small economies, the politics of IMF conditionality, and what Sri Lanka's recovery path offers as a comparative case for the region.

Nobel Prize in Medicine 2026 for optogenetics, controlling neurons with light
Must knowGS-3 · Prelims
The 2026 Nobel Prize in Physiology or Medicine has gone jointly to Karl Deisseroth, Peter Hegemann and Georg Nagel for discovering channelrhodopsin, a light-sensitive protein from algae, and developing optogenetics, a technique that uses light to switch individual neurons on and off with precision.
In essence, they gave scientists a remote control for brain cells: by introducing the algal protein into neurons, flashes of light can activate or silence specific neural circuits, letting researchers map how the brain's electrical networks produce movement, memory, emotion and behaviour. The laureates share 12 million Swedish kronor, about $1.2 million.
Why it matters: optogenetics is now a standard tool in neuroscience, with potential therapeutic applications in Parkinson's disease, epilepsy and memory disorders. Prelims, the 2026 laureates and their discovery; optogenetics as the pairing of light and genetics to control neurons; the Medicine prize opens Nobel week in early October. Mains, how basic research becomes transformative technology, and the ethics of intervening in neural circuits.
UN pre-COP talks open in Fiji ahead of COP31 in Turkey
GS-3
The UN "pre-COP" climate summit opened on Monday in Nadi, Fiji, where Pacific leaders are pressing the world to reckon with life on the frontline of climate change. Prime Minister Sitiveni Rabuka opened the stakeholder programme and Climate Minister Lynda Tabuya addressed the ceremony. The week's talks, also extending to the atoll nation of Tuvalu, are the precursor to COP31, the annual UN climate conference to be held next month in Turkey.
Pre-COP meetings are where negotiating blocs align their positions before the main conference. For Pacific small-island states, the non-negotiables are loss-and-damage finance, adaptation funding and keeping the 1.5 degrees Celsius goal alive.
Why it matters: Prelims, COP31 is the 31st Conference of the Parties to the UNFCCC; Fiji and Tuvalu are Small Island Developing States on the climate frontline. Mains, climate justice, the persistent gap between promised and delivered climate finance, and how pre-COP diplomacy shapes the final negotiated text.

Rangarajan: no GST on UPI merchant fees above Rs 2,000
GS-3
Former RBI Governor C. Rangarajan said on Monday that the GST Council, meeting within a day or two, should state clearly that no GST will be levied on the Merchant Discount Rate (MDR) for UPI transactions above Rs 2,000. Under the new UPI Payment Rules 2026, a 0.4% MDR applies to person-to-merchant transactions above Rs 2,000 from October 15, 2026.
Rangarajan questioned the timing of the levy, noting that 75% of UPI transactions are below Rs 2,000: "perhaps one could have waited", he said, before charging for what is effectively a public good. Taxing the MDR itself, he argued, would pile a further cost on merchants.
Why it matters: the MDR debate pits cost-recovery for banks and payment firms against the zero-cost model that powered UPI's scale; adding GST on the fee would raise the merchant's burden further. Prelims, MDR (the fee merchants pay on digital transactions); UPI as public digital infrastructure built by NPCI; the GST Council under Article 279A. Mains, pricing of public goods, the political economy of digital payments, and whether taxing the rails slows financial inclusion.
India demonstrates its first free-space quantum key distribution link over 5.56 km
GS-3
QNu Labs, together with BISAG-N and IIT Gandhinagar, has demonstrated India's first free-space Quantum Key Distribution (QKD) link over 5.56 km, in a field trial on the night of September 27-28 between the two institutions. The link held the quantum bit error rate below 5% and generated secure keys at 230-260 bits per second, using a pointing, acquisition and tracking system to keep the optical beam aligned.
The generated keys were integrated with Vedic Kavach, BISAG-N's post-quantum cryptography platform, and used for end-to-end encrypted test messages, a complete demonstration from quantum key generation to usable encryption.
Why it matters: free-space QKD, sending quantum keys through the air instead of fibre, is the stepping stone to satellite-based quantum communication and a tamper-evident backbone for critical networks. Prelims, QKD exploits quantum principles so that any eavesdropping disturbs the transmission and is detected; BISAG-N (Bhaskaracharya National Institute for Space Applications and Geo-informatics). Mains, the National Quantum Mission (2023), strategic autonomy in secure communications, and the global race toward quantum-safe cryptography.

First captive-bred Great Indian Bustards released into the wild
GS-3 · Prelims
Two captive-bred male Great Indian Bustards were released on Sunday into the Desert National Park, Jaisalmer, the first time birds raised under Project GIB have been returned to the wild, shifting the programme from breeding to rewilding. The Union Environment Minister and Wildlife Institute of India scientists oversaw the release; the seven-month-old birds were fitted with satellite tags before being set free from a soft-release facility at Sam.
Only about 150 bustards survive in the wild. Under Project GIB, eggs collected from the wild since 2019 have been artificially incubated at two conservation breeding centres in Jaisalmer, at Ramdevra and Sam, to build a founder population for exactly this moment. Eleven birds have been earmarked for release; the facilities now hold close to a hundred birds, with 24 chicks produced in 2025 and 29 in 2026.
Why it matters: the bustard is critically endangered and a flagship of grassland conservation; its decline tracks habitat loss, power-line collisions and hunting pressure. Prelims, GIB (Ardeotis nigriceps), critically endangered, Rajasthan's state bird; Desert National Park; captive breeding versus rewilding. Mains, species-recovery programmes, the limits of ex-situ conservation, and the hard trade-off between renewable-energy expansion across bustard habitat and biodiversity.
