NEWS PEG
  • The 53rd GST Council Meeting chaired by the Union Finance Minister approved major taxpayer relief measures, waiving interest and penalties for demand notices issued under Section 73 of the CGST Act for non-fraudulent bona fide errors during the initial implementation years (FY 2017–18 to 2019–20).
  • The Council recommended setting up a uniform monetary threshold for tax department appeals before appellate tribunals (₹20 lakh for GSTAT, ₹1 crore for High Courts, ₹2 crore for Supreme Court) to drastically declog tax litigation.
  • Key citizen-centric decisions included exempting platform tickets and waiting room services provided by Indian Railways from GST and capping corporate guarantees among group entities at 1%.
STATIC FOUNDATION
  • Section 73 vs Section 74 (CGST Act, 2017): Section 73 governs determination of tax unpaid/short-paid for reasons OTHER than fraud, willful misstatement, or suppression of facts; Section 74 deals with cases involving deliberate fraud/suppression.

03 · GS-III: Defense Technology, Hypersonic Propulsion & Deterrence

Hypersonic Missile Technology: Hypersonic Technology Demonstrator Vehicle (HSTDV), Scramjet Engines and Strategic Deterrence

NEWS PEG
  • The Defense Research and Development Organisation (DRDO) conducted successful flight trials of its indigenous Hypersonic Technology Demonstrator Vehicle (HSTDV), demonstrating sustained flight at speeds exceeding Mach 6 (over 7,000 km/h) using an indigenous scramjet engine.
  • Military defense strategists highlighted that hypersonic glide vehicles (HGVs) and hypersonic cruise missiles fly in the upper atmosphere along unpredictable non-ballistic trajectories, rendering conventional radar tracking and ballistic missile defense (BMD) interceptors ineffective.
  • The breakthrough places India among an elite group of four nations (alongside USA, Russia, China) possessing indigenous hypersonic scramjet propulsion capabilities.
STATIC FOUNDATION
  • Hypersonic Speed: Velocities exceeding Mach 5 (five times the speed of sound, ~6,174 km/h).
  • Ramjet vs Scramjet Engine:
  • Ramjet: Operates by combusting fuel in a stream of air compressed by the forward speed of the aircraft; airflow through the combustion chamber is slowed to subsonic speeds (efficient up to Mach 5).
  • Scramjet (Supersonic Combusting Ramjet): Airflow through the entire engine remains supersonic throughout combustion; highly efficient for speeds between Mach 5 and Mach 15.
  • Hypersonic Glide Vehicle (HGV) vs Ballistic Missile: Ballistic missiles follow a predictable parabolic trajectory in space; HGVs are boosted by rockets into the upper atmosphere and glide/maneuver unpredictably to target.
PRELIMS TRAP & PYQ BRIDGE MAINS ENHANCEMENT
  • Strategic Deterrence Stability: Overcoming Advanced Missile Shields — How hypersonic maneuvering capabilities maintain credible minimum deterrence against regional adversaries.
  • Frontier Materials Engineering: Ultra-High Temperature Ceramics (UHTCs) — Developing carbon-carbon composites capable of withstanding intense 2,000°C atmospheric friction heat.

04 · GS-III: Industrial Policy, Electric Mobility & Urban Transport

Electric Mobility Transition (FAME-III / EMPS): Public Transport Electrification, Charging Grid Infrastructure and Battery Recycling

NEWS PEG
  • The Ministry of Heavy Industries rolled out the operational guidelines for the Electric Mobility Promotion Scheme (EMPS) with a dedicated allocation of ₹500 crore to bridge the transition toward the upcoming FAME-III framework.
  • The policy shifts direct subsidy focus away from private four-wheelers toward commercial electric two-wheelers, three-wheelers (e-rickshaws), and public municipal e-buses under PM-eBus Sewa.
  • Urban transport studies showed that while commercial EV penetration crossed 18% in two-wheelers and 54% in three-wheelers, inadequate high-speed public charging plazas and unstandardized battery-swapping protocols remain key adoption barriers.
STATIC FOUNDATION
  • FAME India Scheme (Faster Adoption and Manufacturing of Electric Vehicles): Launched in 2015 under National Electric Mobility Mission Plan (NEMMP); FAME-II had an outlay of ₹10,000 crore focusing on demand incentives and public charging infrastructure.
  • PM-eBus Sewa Scheme: Approved with ₹57,613 crore outlay to deploy 10,000 electric buses in 169 cities on Public-Private Partnership (PPP) model.
  • Battery Swapping Policy (NITI Aayog): Proposes interoperability standards, unique battery identification numbers, and equalized GST on loose batteries and charging services (5%).
  • Environmental Lifecycle Impact: EVs produce zero tailpipe emissions; total lifecycle decarbonization depends on grid power mix (transitioning from coal to renewables).
PRELIMS TRAP & PYQ BRIDGE MAINS ENHANCEMENT
  • Prioritizing Public & Commercial Electrification: Maximizing Emission Reductions per Subsidy Rupee — Why targeting high-mileage commercial fleets and city buses yields greater climate benefits than private luxury EVs.

05 · GS-II: Indian Constitution, Tribal Autonomy & Sixth Schedule

Sixth Schedule Autonomy and Autonomous District Councils (ADCs): Legislative Powers, Financial Devolution and Article 244(2)

NEWS PEG
  • The Ministry of Home Affairs held high-level tripartite talks with representatives from the 10 Autonomous District Councils (ADCs) of Assam, Meghalaya, Tripura, and Mizoram to address long-standing demands for direct central funding and expanded legislative autonomy.
  • ADC leaders highlighted that under the current architecture of Article 244(2) and the Sixth Schedule, financial allocations are routed through State governments, leading to delays, administrative bottlenecks, and discretionary cuts.
  • The Union Government discussed draft constitutional amendments to empower the State Finance Commissions to recommend direct budgetary transfers to ADCs and establish Village Councils for grassroots participatory democracy.
STATIC FOUNDATION
  • Sixth Schedule (Articles 244(2) & 275(1)): Provides for administration of tribal areas in 4 North-Eastern States: Assam, Meghalaya, Tripura, and Mizoram (AMTM); creates Autonomous District Councils (ADCs) and Regional Councils.
  • Powers of ADCs: Legislative powers on land, forests (other than reserved forests), canal water, shifting cultivation, village committees, marriage, divorce, and social customs (laws require Governor's assent); judicial powers to constitute village courts; taxing powers on land revenue, vehicles, and trades.

06 · GS-III: Environment, Atmospheric Chemistry & Black Carbon

Black Carbon Depletion on Himalayan Glaciers: Radiative Forcing, Albedo Reduction and Clean Cooking Transitions

NEWS PEG
  • Atmospheric research stations operated by the Wadia Institute of Himalayan Geology (WIHG) recorded a surge in Black Carbon (BC) concentrations over Gangotri and Dokriani glaciers during pre-monsoon biomass burning seasons.
  • The study demonstrated that black carbon soot deposits darken the pristine snow surface, reducing surface albedo from 85% to under 50% and absorbing solar radiation, which accelerates summer glacier mass loss by up to 30%.
  • Environmental scientists urged the rapid expansion of clean cooking gas under the Pradhan Mantri Ujjwala Yojana (PMUY) and agricultural crop residue pelletization to eliminate domestic fuelwood combustion and open field stubble fires across the Indo-Gangetic plains.
STATIC FOUNDATION
  • Black Carbon (Soot): Pure form of carbon produced by incomplete combustion of fossil fuels, biofuels, and biomass; it is a Short-Lived Climate Pollutant (SLCP) with a lifetime of days to weeks in the atmosphere but a global warming potential 460–1500 times higher than CO2.
  • Albedo Effect: Fraction of solar radiation reflected by a surface; fresh snow has high albedo (0.8–0.9), while soot-covered darkened snow absorbs heat and melts rapidly.
  • Sources of Black Carbon in South Asia: Residential biomass cookstoves (~45%), industrial brick kilns & diesel exhaust (~30%), and open agricultural biomass burning (~25%).
  • Climate and Clean Air Coalition (CCAC): Global voluntary partnership under UNEP to reduce Short-Lived Climate Pollutants (Methane, Black Carbon, HFCs).
PRELIMS TRAP & PYQ BRIDGE MAINS ENHANCEMENT
  • Mitigating Cryosphere Melting: Controlling Short-Lived Climate Pollutants (SLCPs) — Why cutting black carbon yields immediate local cooling benefits for Himalayan glaciers.
  • Sustaining Ujjwala LPG Adoption: Targeted Refill Subsidies — Preventing rural households from sliding back to polluting biomass cookstoves due to commercial cylinder refill costs.
  • Zig-Zag Brick Kiln Modernization: Industrial Emission Standards — Mandating cleaner combustion technology in Indo-Gangetic brick manufacturing clusters.
