The Supreme Court dismissed a petition seeking to block caste enumeration in Census 2027, ruling that the decision to count castes lies within the "policy domain" of the executive and is not justiciable as a fundamental rights question.

• First since 1931: a comprehensive caste enumeration was last conducted in 1931 under British India. The 1941 census collected the data but it was never published. The 2027 exercise will be the first post-independence enumeration of Other Backward Classes.
• Cabinet approval: the Union Cabinet Committee approved the caste enumeration component of Census 2027 in April 2025.
• Mandal Commission (1980): Justice B.P. Mandal's commission estimated OBCs at 52 per cent of India's population, using 1931 data. This formed the basis for the 27 per cent OBC reservation in central government jobs upheld in Indra Sawhney (1992).
• SECC 2011: the Socio-Economic and Caste Census of 2011 captured caste data and found 46 lakh distinct caste names, but this data was never officially published or used for policy purposes.
• Bihar Caste Survey (2023): the Bihar government found that OBCs and Extremely Backward Classes together constitute 63 per cent of the state's population, significantly above the Mandal Commission estimate.
• Constitutional tension: Article 17 abolishes untouchability and implicitly points toward a caste-free society; Articles 15(4), 16(4), and 340 simultaneously use caste as a category for affirmative action. The census exercise sits at this constitutional intersection.

Operation Sindoor (May 7-10, 2025) provided India's first operational experience of modern drone warfare at scale, revealing both the potential of loitering munitions and critical gaps in India's air defence doctrine.

• Loitering munitions: also called kamikaze drones, these are unmanned aerial vehicles that loiter over a target area and then dive into the target on command or autonomously. They combine the persistence of a reconnaissance drone with a warhead.
• Iron Beam (Israel): a laser-based air defence system that intercepts drones and missiles at a cost of $2-3.50 per laser shot. This contrasts sharply with the $40,000-50,000 per missile cost of the Iron Dome kinetic interceptors.
• Cost asymmetry: the fundamental problem of modern air defence is that a defending nation spending $50,000 per interception to destroy a $500 drone is unsustainable at scale. Laser systems address this asymmetry.
• India's Sudarshan Chakra: India's planned integrated air defence system includes laser and directed-energy components. The programme has a target completion date of 2035.
• Fibre-optic FPV drones: first-person view drones guided by fibre-optic cables (rather than radio frequencies) cannot be jammed by electronic warfare systems because they carry no radio signal. Operation Sindoor encountered this limitation.
• Doctrinal implication: drone warfare has lowered the cost of offensive operations while raising the cost of defence, requiring a rethink of India's layered air defence architecture.

GS area: International Relations (India-Europe)

India upgraded bilateral ties with Italy to a Special Strategic Partnership, with Prime Minister Modi also receiving the FAO Agricola Medal 2026 from the Food and Agriculture Organisation's Director-General.

• Defence Industrial Road Map: India and Italy agreed a roadmap for co-production in naval platforms, helicopters, and aerospace. Italy's Leonardo and Fincantieri are among the defence firms with Indian interest.
• Critical Minerals MoU: the MoU covers cooperation in sourcing, processing, and recycling of critical minerals. Italy has interests in African critical mineral supply chains and India is building a raw material partnership with several African nations.
• IMEC corridor: the India-Middle East-Europe Economic Corridor includes Italy as a terminal point in Europe. The partnership advances the connectivity and trade dimension of IMEC.
• FAO Agricola Medal: awarded by the Food and Agriculture Organisation for exceptional service in the field of agriculture and food security. PM Modi is the first Indian Prime Minister to receive this award.
• India-Italy trade: bilateral trade is approximately $14-15 billion. Italy is among India's top five EU trade partners.

Three Union Ministries jointly expressed opposition to new hydroelectric projects in the upper Ganga basin, covering the Alaknanda and Bhagirathi river systems, citing ecological sensitivity and disaster risk.

• 2013 Kedarnath disaster: the June 2013 flash floods and landslides in Uttarakhand killed over 5,000 people and destroyed infrastructure worth thousands of crores. Multiple hydro projects under construction were identified as aggravating factors.
• Rishiganga flood (2021): a glacial lake outburst flood in February 2021 destroyed the Rishiganga power plant and severely damaged the 520 MW Tapovan Vishnugad project under construction.
• Seismic Zone V: the entire upper Ganga basin falls within Seismic Zone V, the highest seismic hazard category in India. Dam construction in this zone carries exceptional risk.
• Ecological sensitivity: the Alaknanda and Bhagirathi basins are the source streams of the Ganga. Multiple National Park and wildlife sanctuary boundaries intersect the proposed project areas.
• National Green Tribunal: the NGT has examined several upper Ganga hydro projects and has stayed or conditioned environmental clearances for projects found to violate the Environment (Protection) Act or the Forest (Conservation) Act.
• Existing projects: the moratorium applies to new projects. Existing projects such as Tehri (1,000 MW) and Nathpa Jhakri (1,500 MW) on the Sutlej (a separate basin) are not affected.

An analysis of eleven high-GDP Indian states' budgets for 2024-25 found that India's justice system is structurally imbalanced, spending heavily on police while systematically underfunding courts and legal aid.

• Total justice budget: Rs 2 lakh crore across the eleven states studied, equivalent to approximately 4.6 per cent of their combined state budgets.
• Police share: policing accounts for over 80 per cent of the justice budget. Per capita spending on police is approximately Rs 1,616.
• Judiciary share: courts receive less than 1 per cent of the justice budget. Per capita judicial spending is approximately Rs 450.
• Legal aid: per capita spending on legal aid is approximately Rs 9, among the lowest in comparable democracies.
• Judge-to-population ratio: India has approximately 15 judges per 10 lakh population. The Law Commission has recommended raising this to 50 per 10 lakh, a benchmark drawn from comparative international data.
• Prison occupancy: prisons are operating at 137 per cent capacity. Over 60 per cent of prison inmates are undertrials awaiting trial rather than convicted prisoners.
• Arrests: approximately 26 lakh persons were arrested in 2024 across India, many for petty offences. High arrest rates feed directly into the undertrial population and prison overcrowding.

Tamil Nadu announced India's first state-owned Green Climate Fund with an initial corpus of Rs 1,000 crore, alongside a dedicated climate budget of Rs 3,000 crore and a Governing Council on Climate Change chaired by the Chief Minister.

• Green Climate Fund (state-level): distinct from the international Green Climate Fund (GCF) headquartered in Incheon, South Korea. The Tamil Nadu fund is a state fiscal mechanism, not a borrowing from the GCF.
• Governing Council on Climate Change: a high-level coordination body chaired by the Chief Minister, bringing together departments of energy, agriculture, water resources, and forests under a unified climate governance structure.
• TN Shore Mission: a coastal adaptation programme supported by the World Bank, covering shoreline protection, mangrove restoration, and coastal community resilience.
• EV charging targets: Tamil Nadu plans to install 20,000 EV charging stations by 2031 as part of its clean transport transition.
• Climate budget: a dedicated Rs 3,000 crore climate budget marks a shift from project-level spending to a cross-sectoral, multi-year commitment. Only a handful of Indian states have a standalone climate budget line.

India is actively deepening LNG trade with Australia as a strategic alternative to Persian Gulf and Red Sea supply routes, with Australian cargoes transiting the Indian Ocean without crossing any of the current conflict chokepoints.

• Route advantage: Australian LNG from the North West Shelf and Darwin projects travels directly across the Indian Ocean to India's east coast ports (Ennore, Kakinada), avoiding the Strait of Hormuz, the Bab el-Mandeb, and the Malacca Strait.
• Australia's lithium: Australia holds approximately 47 per cent of the world's recoverable lithium reserves. An LNG partnership with Australia can be embedded in a broader critical minerals partnership.
• ECTA 2022: the India-Australia Economic Cooperation and Trade Agreement signed in April 2022 reduced tariffs significantly: textiles by 25 per cent, agricultural goods by 50 per cent, and automobiles by 85 per cent.
• East coast LNG capacity: India's east coast LNG regasification capacity is currently limited. Ennore (Tamil Nadu) and Kakinada (Andhra Pradesh) are the primary terminals but lack the scale of west coast facilities at Hazira and Dahej.
• Quad linkage: the Quadrilateral Security Dialogue (India, US, Japan, Australia) has a clean energy working group. Australian LNG and lithium cooperation with India is one output of this framework.

• Sperm whale communication (Royal Society B, April 2026): researchers found five-layer acoustic complexity in sperm whale click patterns. Two click types function like vowels. Project CETI uses AI and machine learning to decode whale communication. The study notes convergent evolution: both humans and sperm whales independently developed complex combinatorial communication systems.
• Article 39A: the Directive Principle in Article 39A directs the state to ensure free legal aid for citizens who cannot afford legal costs. The Legal Services Authorities Act, 1987 gives statutory form to this directive. The Rs 9 per capita legal aid finding reveals how far the reality is from the constitutional aspiration.
