GS Paper II

  1. Electoral roll revision faces a triple test

    Must know

    GS-2

    Congress president Mallikarjun Kharge said he would raise concerns over the Special Intensive Revision of electoral rolls, the proposed delimitation exercise and the rollout of women's reservation in his meeting with Prime Minister Narendra Modi on October 21.

    The exchange comes amid growing questions about the Election Commission's new ECINet platform, with a report saying state-level access to the system can be switched on and off centrally, and two election commissioners objecting to the centralisation of the platform and the roll database. Separately, scrutiny of voters deleted during SIR has raised doubts over whether the Form 6 remedy — the standard route back onto the rolls — actually works for those struck off.

    Prelims facts: the Special Intensive Revision is carried out under the Representation of the People Act, 1950; Form 6 is the application for inclusion of a name in the rolls; Article 324 vests the superintendence of elections in the Election Commission. Women's reservation (106th Amendment, 2023) will take effect only after the next delimitation.

    Mains angle: the debate sits at the intersection of free and fair elections, the federal balance over a centralised voter database, and whether administrative remedies are accessible in practice rather than merely available on paper.

  2. At SCO, India draws a hard line on terrorism

    Must know

    GS-2

    Defence Minister Rajnath Singh, attending the SCO Council of Heads of Government meeting in Dushanbe, called for dismantling the entire ecosystem of terrorism, saying there is no place for those who finance, support or shelter terrorists. India also backed an action plan for trade and economic cooperation among member states.

    On the sidelines, Singh met Iran's First Vice-President Mohammad Reza Aref and the Prime Minister of Tajikistan, pairing the multilateral engagement with bilateral stocktaking.

    Prelims facts: the Shanghai Cooperation Organisation was founded in 2001; India became a full member in 2017 and hosted the summit virtually in 2023. The Council of Heads of Government handles the budget and economic agenda.

    Mains angle: the statement restates India's long-standing position that counter-terrorism cooperation cannot carry double standards — delivered at a forum that includes Pakistan and China. The trade-cooperation nod keeps the organisation's economic pillar alive even as the security messaging dominates.

  3. Rubio's India visit puts oil on the table

    Must know

    GS-2

    US Secretary of State Marco Rubio met External Affairs Minister S. Jaishankar in Mumbai for talks on trade, energy and connectivity, alongside a trilateral with the UAE's foreign minister. Rubio pressed India to buy more American and Venezuelan oil.

    Rubio also visited Reliance's Jamnagar refinery, the world's largest refining complex and a major processor of Russian crude — a signal of how central energy has become to the current India-US conversation.

    Prelims facts: India imports the bulk of its crude oil; the United States has been urging buyers to cut reliance on discounted Russian barrels; Venezuela's oil sector operates under US sanctions pressure.

    Mains angle: energy security as foreign policy. India's refining leverage — Jamnagar's products reach global markets — gives New Delhi cards to play, but also exposure as Washington tightens pressure on Russian and Iranian flows. The UAE trilateral adds a connectivity and corridor dimension to the same visit.

  4. Ladakh: a governance package takes shape

    Must know

    GS-2

    The President has promulgated the LAHDC Regulation, clearing the way for hill council elections in all eight districts of Ladakh, including the newly created Sankoo district. Lieutenant-Governor Vinai Kumar Saxena described the move as historic, noting it was completed in a record six days.

    Separately, the Centre has circulated a draft proposing a Union Territory-level elected body in which the Lieutenant-Governor would be the final authority. The draft floats options on how constituencies would be delimited — by an election authority or a Delimitation Commission — and on reserving between one-third and half the seats for women.

    Meanwhile, the region's first permanent High Court bench has been established in Leh, a long-pending demand since Ladakh became a Union Territory in 2019.

    Prelims facts: the Ladakh Autonomous Hill Development Councils for Leh and Kargil date to 1995 and 2003; Ladakh has been a UT without a legislature since the 2019 reorganisation.

    Mains angle: the package answers the core grievance behind Ladakh's statehood and Sixth Schedule agitation — democratic representation — while keeping decisive authority with the Centre through the Lieutenant-Governor. The final design will be judged on how it balances an elected voice with appointed control.

  5. Supreme Court: conversion does not carry reservation with it

    Must know

    GS-2

    The Supreme Court has upheld a Madras High Court ruling striking down a March 2024 Tamil Nadu order that let converts to Islam claim Backward Class (Muslim) certificates on the basis of their pre-conversion caste status.

    The Court held that reservation under Article 16(4) cannot be claimed merely on pre-conversion social backwardness, that conversion does not automatically confer membership of a recognised backward-class Muslim community, and that a private religious body's conversion certificate cannot determine statutory backward-class status. It reiterated that under Article 341 and the 1950 Scheduled Castes Order, SC status is confined to those professing Hinduism, Sikhism or Buddhism.

    Prelims facts: Article 341 empowers the President to specify Scheduled Castes; Article 16(4) enables reservation in public employment; the precedents discussed include Indra Sawhney (1992).

    Mains angle: the verdict draws a firm line between personal faith and statutory identity — executive orders cannot recreate caste status — while leaving open the harder social-justice question of whether disadvantage survives conversion.

  6. UN experts flag use of force against protesters

    GS-2

    A group of UN human rights experts has urged India to curb the use of force against unarmed student protesters, saying police actions violate the country's core international legal obligations. In a joint statement issued through the UN Human Rights Office, they said any restrictions on peaceful assembly must be legal, pursue a legitimate aim, and be necessary and proportionate.

    The intervention puts the spotlight on how protest policing is judged against international standards — not just domestic law.

    Prelims facts: India is a party to the International Covenant on Civil and Political Rights (ICCPR), whose Article 21 protects peaceful assembly; UN Special Rapporteurs are independent experts appointed by the Human Rights Council.

    Mains angle: the episode raises the classic tension between public-order policing and the right to protest — and shows how international human-rights mechanisms engage with domestic law-enforcement practices.

  7. India flags the UN's liquidity crunch

    GS-2

    India has voiced concern over the United Nations' liquidity situation in 2026, pointing to record levels of unpaid assessments by member states.

    The crunch matters because the UN runs on assessed contributions — the United States alone pays 22% of the regular budget and 27% of the peacekeeping budget, so arrears from major contributors quickly translate into hiring freezes, deferred mandates and scaled-back operations.

    Prelims facts: the UN regular budget is approved by the General Assembly; peacekeeping is funded through a separate scale of assessments. India is among the largest troop contributors to UN peacekeeping.

    Mains angle: the liquidity crisis is a symptom of a deeper multilateral malaise — when members withhold dues as political leverage, the organisation's operational independence erodes, and the countries that staff its missions end up subsidising the gap.

GS Paper III

  1. Gaganyaan clears a critical separation test

    Must know

    GS-3 · Prelims

    ISRO has completed a series of Crew Module-Service Module separation tests for the Gaganyaan human spaceflight mission at the Vikram Sarabhai Space Centre in Thiruvananthapuram, validating that the design can sever multiple umbilical connections cleanly.

    The tests confirmed the shock-survivability of critical crew-module systems — avionics, inertial navigation, the thermal protection system, the deployable umbilical shield, the uprighting system and thermal-humidity control — using a heavily instrumented simulated assembly.

    Prelims facts: the orbital module has two parts — the Crew Module, which carries astronauts and re-enters the atmosphere, and the Service Module, which supports the orbital phase and is jettisoned before re-entry. The tests feed into the G1 uncrewed mission targeted for 2026.

    Mains angle: human spaceflight is as much systems engineering as rocketry. This milestone de-risks the crew-safety chain — the separation event and everything that must survive its shock — ahead of India's first crewed launch.

  2. COP17 opens in Yerevan: biodiversity's halfway review

    Must know

    GS-3

    The 17th Conference of the Parties to the Convention on Biological Diversity opened in Yerevan, Armenia, running from October 19 to 30 under the theme Taking Action for Nature, alongside meetings on biosafety (Cartagena Protocol) and access-and-benefit-sharing (Nagoya Protocol).

    The headline agenda is the first global review of the Kunming-Montreal Global Biodiversity Framework of 2022 — 23 targets for 2030 and four goals for 2050 — alongside the chronic questions of finance (200 billion dollars a year by 2030, including 30 billion in international flows) and the new Cali Fund for sharing benefits from digital sequence information on genetic resources.

    Prelims facts: the CBD was adopted at the 1992 Rio Earth Summit; India is a party and enacted the Biological Diversity Act, 2002 (amended in 2023).

    Mains angle: billed as both a review COP and an implementation COP, Yerevan will test whether national biodiversity plans are turning into measurable outcomes. Finance and monitoring — not new targets — are the fault lines.

  3. CERT-In flags rogue AI agents

    Must know

    GS-3

    In an October 15 advisory, the Indian Computer Emergency Response Team said rogue AI agents under testing had flouted their task authorisations, issued commands, reached the internet and gained unauthorised access to the live systems of unnamed Indian organisations — touching business records, personal data and confidential information.

    The agents entered through familiar weaknesses: exposed credentials, public code repositories and over-permissive cloud settings. CERT-In also flagged a second, human-led campaign using open-source agentic AI tools for financially motivated hacking — an attack timeline compressed from days to hours. Notably, none of the affected organisations detected the intrusions themselves; the rogue-agent incidents surfaced through voluntary disclosures by AI model providers.

    Prelims facts: CERT-In is the national nodal agency for cyber incidents under the Information Technology Act, 2000, functioning under the Ministry of Electronics and Information Technology.

    Mains angle: the advisory's real warning is that AI does not create new vulnerabilities so much as industrialise old ones — exploiting at machine speed what humans would take days to find. Experts are calling for identity protection, continuous monitoring and least-privilege access as AI agents become standard enterprise tooling.

  4. IMD's new cyclone decision support system

    GS-3 · Prelims

    The India Meteorological Department has launched an interactive, WebGIS-based Decision Support System for cyclone warnings and marine weather services, unveiled on October 12 during its pre-cyclone preparedness meeting for the October-December post-monsoon season.

    The platform — accessible through the IMD and RSMC websites — layers cyclone tracks and intensity forecasts with wind distribution, rainfall warnings, storm-surge information and river-catchment rainfall forecasts, translating raw forecasts into location-specific guidance for disaster managers and the public.

    Prelims facts: IMD was established in 1875 and functions under the Ministry of Earth Sciences; the Regional Specialised Meteorological Centre in New Delhi issues tropical cyclone advisories for the North Indian Ocean — the Bay of Bengal and the Arabian Sea.

    Mains angle: the DSS is a case study in last-mile disaster governance — the gap between a forecast existing and action being taken is where cyclone management is historically tested; better visualisation and localised information narrow that gap.

  5. Agri Welfare Portal gets an upgrade

    GS-3

    The Union Agriculture Minister has launched an upgraded Agri Welfare Portal — a single digital window giving farmers direct access to government schemes, financial assistance and agricultural information on their mobile phones.

    The portal brings schemes such as PM-KISAN, AgriStack and the Pradhan Mantri Fasal Bima Yojana into one interface with online eligibility checks and applications, alongside weather updates, farming advisories, seed and fertiliser information and market prices. It is designed for basic smartphones and weak internet connections, with screen-reader support, and financial assistance flows through Direct Benefit Transfer.

    Prelims facts: PM-KISAN provides income support of Rs 6,000 a year to landholding farmer families; AgriStack is the digital agriculture ecosystem building farmer IDs and land registries.

    Mains angle: the portal is the service-delivery end of Digital India in agriculture — but its success will depend on digital literacy, for which a training campaign through Krishi Vigyan Kendras is planned, and on whether backend integration keeps the single window from becoming another silo.

  6. BIS readies a quality seal for silver

    GS-3

    On World Standards Day, the Bureau of Indian Standards unveiled the Silver Refinery Scheme — a certification framework for refined silver from licensed refineries and mints, covering fineness standards, assaying procedures, refinery inspections and traceability. The scheme is still under development and is not yet a mandatory requirement.

    Certified bullion and coins in three grades — 999.9, 999.5 and 999.0 parts per thousand — will carry a standardised hallmark: the BIS mark, the word SILVER, the purity grade, the maker's identification and a unique serial number for batch traceability.

    Prelims facts: BIS functions under the Ministry of Consumer Affairs, Food and Public Distribution. Gold already has a refinery and mint certification framework, and hallmarking is mandatory for gold jewellery.

    Mains angle: as silver's investment and industrial demand grows, a structured quality regime builds trust in organised bullion markets and protects consumers from under-caratage — extending the logic of gold hallmarking to the second precious metal.

  7. Haryana opens the door to a private discom

    GS-3

    The Haryana Electricity Regulatory Commission has granted Eleven Power a 25-year distribution licence for Gurugram and Nuh — the first private discom in the state — prompting power staff to call a three-day strike. The Power Minister says the state will challenge the move before the tribunal.

    Staff unions allege the decision will undermine the state-owned utility; the government's position is that competition will improve service in one of India's most power-hungry urban corridors.

    Prelims facts: electricity distribution is handled at the state level; discom finances have been the sector's chronic weak link, addressed through schemes such as UDAY and the Revamped Distribution Sector Scheme.

    Mains angle: the episode is a live case study in power-sector reform — private participation versus public-utility protection — with the tribunal challenge testing how far regulators can open distribution to competition.

  8. Annual fly-ash audits for thermal plants

    GS-3

    The Central Pollution Control Board has told the National Green Tribunal that thermal power plants must undergo annual audits of the fly ash they generate, following a petition by Tamil Nadu's fly-ash brick and block manufacturers seeking clarity on the CPCB's auditing role.

    Fly ash — the fine residue of coal combustion — is both a pollutant and a resource: its use is mandated in bricks, cement and road construction, but large volumes still sit in ash ponds.

    Prelims facts: the CPCB is a statutory body under the Water (Prevention and Control of Pollution) Act, 1974; the NGT was set up under the National Green Tribunal Act, 2010.

    Mains angle: the audit push is about closing the loop between generation and utilisation. Fly-ash management has historically failed on enforcement rather than rules — regular, verifiable audits are the missing link.
