Pre & Mains Notes

1. Special Summary Revision: what EC announced, how it differs from SIR WHAT HAPPENED Amid protests against the SIR, the EC announced the Special Summary Revision schedule for 17 States/UTs, including five that vote in 2027. Final roll: January 4, 2027. CORE ISSUE SSR is the routine annual update of electoral rolls; SIR was an intensive, one-off revision after 20 years in which every elector had to re-establish eligibility. KEY DETAILS • Legal base: Article 324 + RP Act 1950 + Registration of Electors Rules 1960 • SSR: existing electors auto-included in draft roll; new electors at 18+ as of Jan 1, 2027; deletions only after notice and hearing • SIR: enumeration form + documents incl. citizenship; 13+ crore draft deletions; central "logical discrepancy" notices - absent in SSR • Polling-station rationalisation by November 2; claims/objections for a month WHY IT MATTERS GS Paper II – Polity: Election Commission. Article 324, RP Act 1950 and roll-revision types are prelims staples. 2. Economics Nobel 2026: how expectations shape consumption and prices WHAT HAPPENED Robert E. Hall and Michael Woodford win for quantifying the forward-looking behaviour of households (consumption) and companies (pricing). CORE ISSUE People and firms act today on what they expect tomorrow - measuring this improves policy targeting and communication. KEY DETAILS • Hall: identified the exact share of "hand-to-mouth" households - vital for fiscal support in supply shocks • Woodford: firms' future expectations drive current prices; PMI tracks a month ahead, longer-horizon surveys needed • India lesson: 81+ crore get free food on 13-15-year-old estimates; better data can streamline subsidy spend WHY IT MATTERS GS Paper III – Economy. Nobel picks are prelims regulars; subsidy targeting and policy communication are mains themes. 3. India-China trade: rising deficit, denied market access, tech export curbs WHAT HAPPENED FM Sitharaman said the trade imbalance with China is "growing exponentially" and market access has been denied for a decade; Beijing said "let's work on it". China also announced curbs on exports of key technologies like AI. CORE ISSUE Non-tariff barriers and tech export controls are now the main levers in India-China economic ties. KEY DETAILS • Deficit widened to $68.9 bn in Apr-Sep, from $54.4 bn a year ago; China is the largest import source • India prefers talks, not punitive action; exports to China up 36% this year • China's tech export curbs are a supply-chain risk for India's electronics and AI push WHY IT MATTERS GS Paper III – Economy: External Sector. Deficit data for prelims; NTBs and export controls for mains.

Pre & Mains Notes

1. OCI cardholders: a visa privilege, not citizenship WHAT HAPPENED Government's wide powers over OCI cardholders are in focus after actor Imran Khan, an OCI, was told to leave India; Delhi HC upheld the notice. CORE ISSUE OCI is a facility for foreign citizens of Indian origin - not dual citizenship, and not a right. KEY DETAILS • OCI: Introduced in 2005 under the Citizenship Act; lifelong, multi-entry visa. • Excluded: Voting, constitutional posts, government jobs, buying agricultural land. • Cancellation: FRRO can cancel (fraud, "disaffection"); Aatish Taseer, Ashok Swain earlier cases. • New law: Immigration and Foreigners Act, 2025 replaced the Foreigners Act, 1946; wider powers. WHY IT MATTERS Separate citizenship from OCI privileges; Article 19 rights are for citizens only. GS Paper II — Polity: Citizenship. 2. Conversion does not carry reservation benefits: SC WHAT HAPPENED SC refused to interfere with a Madras HC judgment; a man who converted to Islam cannot claim the backward-class reservation of his antecedent caste. CORE ISSUE Reservation under Article 16(4) targets social backwardness tied to the Hindu caste order; conversion changes the basis of the claim. KEY DETAILS • Ruling: Caste identity is not an immutable personal attribute after conversion. • 1950 Order: SC status limited to Hindus, Sikhs and Buddhists. • Distinction: Article 25 protects faith; reservation is a separate constitutional benefit. WHY IT MATTERS Links reservation, conversion and social justice - a recurring prelims and mains theme. GS Paper II — Social Justice. 3. A contested UNSC seat poses a test for India WHAT HAPPENED After the 81st UNGA session, India is pushing its bid for a 2028-29 non-permanent UNSC seat; vote in June 2027. CORE ISSUE India faces Tajikistan for the Asia-Pacific seat; needs two-thirds of UNGA - at least 129 of 193 votes. KEY DETAILS • UNSC: 5 permanent (veto) + 10 non-permanent members elected for two years. • Track record: India has served eight terms; last was 2021-22. • Signals: Kyrgyzstan beat the Philippines; Germany lost to Portugal and Austria. • Options: Contest, persuade Tajikistan to withdraw, or withdraw. WHY IT MATTERS UNSC reform and India's multilateral diplomacy are prelims and mains staples. GS Paper II — International Relations: United Nations.

Pre & Mains Notes

1. Inflation: WPI is not the household bill WHAT HAPPENED Wholesale inflation rose to 11.4% in September. CORE ISSUE Different price indices measure different baskets and stages of sale. KEY DETAILS • WPI: Wholesale goods prices; excludes services. • CPI: Retail prices of household goods and services. • Base effect: A low year-earlier price level can push up annual inflation. WHY IT MATTERS Distinguish wholesale inflation from the cost of living; understand supply shocks. GS Paper III - Economy: Inflation. 2. Self-help groups: credit to livelihoods WHAT HAPPENED An editorial flags the support gap for women's SHGs after the urban livelihoods mission ended. CORE ISSUE A loan alone does not ensure a lasting livelihood. KEY DETAILS • SHGs: Pool savings, lend internally and access bank credit. • Empowerment: Financial literacy, collective voice and household decision-making. • Missing links: Skills, markets and institutional support. • Distinction: DAY-NULM is urban; DAY-NRLM is rural. WHY IT MATTERS Use SHGs to explain financial inclusion, poverty reduction and women's empowerment. GS Paper II - Social Justice. 3. Trade deficit: read the gap, not growth alone WHAT HAPPENED India's goods trade deficit with China reached $105.93 billion in January-September. CORE ISSUE Exports can grow faster yet the deficit can widen because imports start from a larger base. KEY DETAILS • Arithmetic: $125.19 bn imports - $19.26 bn exports = $105.93 bn deficit. • Distinction: Trade deficit is not the government's fiscal deficit. • Composition: Imported inputs can support production; finished-goods dependence raises different concerns. WHY IT MATTERS Understand trade balances, domestic manufacturing and supply-chain dependence. GS Paper III - Economy: External sector.

Pre & Mains Notes

1. PFAS: the gap in drinking-water safety WHAT HAPPENED: Studies find persistent PFAS in Indian water sources; conventional treatment does not reliably remove them. CORE ISSUE: Detecting contamination is not the same as measuring exposure or making water safe. KEY DETAILS • PFAS: Resist degradation because of strong carbon-fluorine bonds. • Treatment: Conventional biological treatment cannot remove them. • BIS: Examining PFAS limits; current drinking-water standard has none. WHY IT MATTERS: Detection alone does not establish health risk; monitor exposure and control pollution at source. GS Paper III - Environment / Pollution & Science 2. BIMSTEC: regional action against terrorism WHAT HAPPENED: The first BIMSTEC Home Ministers' meeting in Delhi adopted the Delhi Declaration on terrorism. CORE ISSUE: Cross-border crime needs coordinated intelligence, financial controls and law-enforcement cooperation. KEY DETAILS • Members: Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka, Thailand. • Focus: Terror financing, recruitment and emerging-technology misuse. • Cooperation: Intelligence, cybercrime, drugs and fugitive repatriation. WHY IT MATTERS: Cross-border threats need regional intelligence and financial cooperation. GS Paper II - International Relations / GS Paper III - Security 3. INS Mangrol: defence in shallow waters WHAT HAPPENED: The Navy commissioned INS Mangrol in Mumbai, strengthening coastal anti-submarine warfare. CORE ISSUE: Shallow coastal waters need specialised platforms to detect and engage underwater threats. KEY DETAILS • Class: Third Mahe-class shallow-water ASW craft; Cochin Shipyard. • Programme: 16 craft from CSL and GRSE; over 80% indigenous content. • Capability: Sonar, waterjet propulsion and coastal submarine detection. WHY IT MATTERS: Protects coastal approaches while freeing larger warships for deep-water roles. GS Paper III - Defence Technology / Maritime Security
