• Polity: The Supreme Court ruled that the Governor cannot withhold assent to Bills indefinitely; it must act within a constitutionally reasonable time.
• Economy: The Reserve Bank of India reported that India's foreign exchange reserves rose to $698 billion, the fourth-highest in the world.
• Environment: The Zoological Survey of India released a State of India's Birds report showing 60 per cent of monitored species declining.
• Science: DRDO tested the Akash-NG (New Generation) missile system; it demonstrated a Mach 3.5 intercept capability.

GS area: Polity (Governor, legislative process)

The Supreme Court held that a Governor's power to withhold assent to a State Bill (Article 200) and reserve a Bill for Presidential consideration (Article 201) is not absolute. The Governor must act within a constitutionally reasonable time and must give reasons if returning a Bill.

• Article 200: After a State Legislature passes a Bill, the Governor may: (a) assent; (b) withhold assent; (c) return the Bill for reconsideration (if not a money Bill); (d) reserve the Bill for Presidential consideration.
• The court's holding: The Governor has no inherent right to sit on a Bill indefinitely. Withholding of assent without time limit or reason is unconstitutional (violates Article 14 and undermines the democratic process).
• Background: Tamil Nadu, Telangana and Punjab had complained that their Governors had kept Bills pending for 2-3 years without action.
• Article 361: The Governor is protected from civil or criminal proceedings while in office. This immunity makes the Governor's passive inaction difficult to challenge directly.
• Pocket veto: The term used for the Governor's prolonged withholding of assent with no formal rejection. The court held that a pocket veto is constitutionally impermissible.
• Precedent (Punjab case, 2023): In the Governor of Punjab case, the SC had already held that reserving a passed Bill for Presidential consideration, when there is no genuine constitutional issue, is an abuse of power.

GS area: Economy (balance of payments, external sector)

The RBI's weekly data showed India's foreign exchange reserves rose to $698 billion as of 18 April 2026, from $648 billion at the start of FY27, driven by strong services exports and FPI inflows after the Russia-India energy deal clarified.

• Components of forex reserves: (1) Foreign currency assets (FCA), (2) Gold reserves, (3) SDRs (Special Drawing Rights from IMF), (4) Reserve Tranche Position with the IMF.
• FCA: The largest component. Held predominantly in US Treasury bonds, euros and a small share in yuan. The currency composition is not publicly disclosed in full.
• Gold reserves: 876 tonnes as of March 2026. Valued at market prices.
• SDRs: An IMF reserve asset. India received a large SDR allocation in August 2021 ($17.86 billion equivalent) as part of the IMF's COVID-19 support.
• Adequacy benchmark: The IMF recommends 3-4 months of import cover. India's $698 billion covers approximately 12 months of imports, one of the most comfortable buffers globally.
• Reserve accumulation strategy: The RBI does not target a specific level. It intervenes to prevent "excessive volatility" in the rupee, buying dollars when the rupee strengthens excessively.

The State of India's Birds 2026 report, a collaborative citizen-science project using eBird data, found that 60 per cent of 942 monitored bird species showed long-term decline, up from 40 per cent in the 2020 report.

• Species of greatest concern: 217 species classified as "high concern," including the Indian Vulture, Sarus Crane, Great Indian Bustard, Bengal Florican and Lesser Florican.
• Cause of decline (ranked): Habitat loss (agriculture and urbanisation) 45 per cent; pesticide use (killing insect food base) 30 per cent; direct hunting 10 per cent; climate change 10 per cent; other 5 per cent.
• eBird: A citizen-science bird-record submission platform run by Cornell Lab of Ornithology. India contributes approximately 25 per cent of global eBird records, making it the platform's largest country dataset.
• Vulture decline: India's vulture crash in the 1990s-2000s was caused by diclofenac (NSAID) used in cattle, which was lethal to vultures feeding on treated carcasses. Diclofenac for veterinary use was banned in 2006.
• Great Indian Bustard (GIB): Fewer than 200 individuals remain. The primary threat is overhead power lines causing collision deaths. A Supreme Court order to underground power lines in GIB habitat areas is partially implemented.
• Wetland birds: 70 per cent of wetland-dependent species showed decline, driven by wetland drainage, dumping and pollution.

GS area: Science and Technology (defence)

DRDO successfully tested the Akash New Generation (Akash-NG) surface-to-air missile system, intercepting a supersonic aerial target at Mach 3.5 speed and 40 km range.

• Akash original system: Inducted into the Indian Army (2015) and Air Force (2014). Range: 25 km. Speed: Mach 2.5. Can engage multiple targets simultaneously.
• Akash-NG improvements: Extended range to 60 km. Higher speed intercept capability (Mach 3.5 target engagement). Active radar seeker (not dependent on ground radar in terminal phase). Better counter-manoeuvring target capability.
• MBDA comparison: Akash-NG competes with the French MICA and the Israeli SPYDER system. India had been relying on imported air defence in mid-range; Akash-NG fills this gap indigenously.
• Integrated Air Command and Control System (IACCS): The Akash systems are linked to IACCS, the Air Force's network-centric air defence umbrella.
• BrahMos distinction: BrahMos is a cruise missile (offensive weapon). Akash is a surface-to-air missile (defensive weapon for destroying hostile aircraft and missiles).
• Export potential: India has approved Akash sales to Philippines, Vietnam and Armenia. The Akash-NG test success increases the system's export attractiveness.

The Ministry of Health's NHM annual report for 2025-26 showed that 22 per cent of rural sub-centres lacked a qualified Auxiliary Nurse Midwife (ANM), and 14 per cent of rural Primary Health Centres operated without a resident doctor.

• NHM (2013): Merger of the National Rural Health Mission (NRHM, 2005) and National Urban Health Mission. Provides financial and technical support to states for public health infrastructure and workforce.
• Sub-centre: The first point of contact between the community and the health system. Staffed by one ANM and one male health worker. Covers 3,000-5,000 population in plains and 1,000-3,000 in hilly areas.
• PHC (Primary Health Centre): Next level. Covers 30,000 population in plains. Must have a government MBBS doctor. Provides outpatient, maternal and child health, and minor surgical services.
• ASHA (Accredited Social Health Activist): Community-level volunteer linking households to ANMs and PHCs. About 10.4 lakh ASHAs across India.
• PMJAY (Ayushman Bharat Pradhan Mantri Jan Arogya Yojana): Provides health insurance of Rs 5 lakh per year for 12 crore poor households. PMJAY covers hospitalisation but not the primary care layer. A weak PHC system means patients often bypass primary care and reach hospitals in avoidable late-stage illness.
• Alma-Ata Declaration (1978): The foundational global document on Primary Health Care (PHC). India is a signatory. The Declaration affirmed that primary care must be accessible to all, universally and equitably.

• National Pension System (NPS) corpus: The PFRDA reported that the NPS corpus crossed Rs 14 lakh crore as of March 2026, up from Rs 11.7 lakh crore in March 2025. It covers 6.8 crore subscribers, both government (Tier I mandatory) and non-government (Tier II voluntary).
• PM-JANMAN tribal welfare scheme: The scheme targeting 75 PVTGs showed that 53 per cent of target households received pucca houses, 71 per cent had clean drinking water connections and 43 per cent had functional electricity connections.
