UPSC Current Affairs – 23 September 2026 | Supreme Court, Groundwater Crisis, AI Governance, Critical Minerals & More
I. POLITY, CONSTITUTION & GOVERNANCE
1. Supreme Court: Refusal to Sing National Song Cannot Invite Criminal Penalty
The Supreme Court observed that a democratically elected government may determine the scope and length of the National Song, but it cannot impose criminal penalties on a person who, on grounds of conscience or religion, refuses to sing one or more stanzas.
The observation came while hearing a challenge to the Prevention of Insults to National Honour (Amendment) Act, 2026, along with administrative directions concerning the rendition of Vande Mataram.
The Court referred to its 1986 judgment in Bijoe Emmanuel v. State of Kerala, which recognised:
- Freedom of conscience
- Freedom of religion
- Constitutional tolerance
- The right to silent objection
The petitioners argued that the later stanzas of Vande Mataram contain devotional references and that compulsory singing under penal sanction could infringe fundamental rights.
Constitutional significance
The issue brings together:
Article 25 → Freedom of conscience and religion
Article 26 → Freedom to manage religious affairs
Article 19 → Freedom of expression
Constitutional secularism → State neutrality towards religion
The key UPSC question is the balance between national symbols and individual constitutional freedoms.
The Court has sought the Union government’s response; therefore, the newspaper report concerns proceedings and observations rather than a final determination on the constitutional challenge.
2. Supreme Court on the Uttar Pradesh Gangsters Act: Criminalisation Must Have Legislative Basis
A significant Supreme Court judgment concerning the Uttar Pradesh Gangsters and Anti-Social Activities (Prevention) Act, 1986 raises the fundamental question: Who has the authority to define a crime?
In Shiv Pratap Singh v. State of U.P. and Himanshu Srivastava v. State of U.P., the Court held that the statutory framework could not leave the essential determination of who qualifies as a “gangster” to executive discretion through subordinate legislation.
Principle of legality
Criminal law is based on the principle:
No crime without law; no punishment without law.
This is expressed through the Latin maxims:
- Nullum crimen sine lege
- Nulla poena sine lege
The principle is reflected in Article 20(1) of the Constitution.
Why is this important?
The judgment highlights the separation of functions:
Legislature → Defines offences and punishments
Executive → Implements the law
Judiciary → Determines guilt according to law
The Court’s concern was that an executive authority should not effectively determine criminal culpability through administrative categorisation.
This is an excellent GS-II topic on separation of powers, rule of law and criminal justice.
3. Delhi SIR: Supreme Court Questions “Mechanically Issued” Notices
The Supreme Court questioned the manner in which notices were issued to more than 33 lakh voters in Delhi during the Special Intensive Revision (SIR) of electoral rolls.
The Court observed that some notices relating to “logical discrepancies” or “no mapping” appeared to have been mechanically generated.
The Bench asked whether voters receiving such notices actually understood what discrepancy they were required to explain.
The Election Commission’s counsel stated that:
- The deadline for disposal of notices was October 29.
- The Commission was open to an extension.
- No name would be deleted without reasons.
The Court sought a status report from the Election Commission.
UPSC relevance
The issue involves:
- Article 324
- Election Commission of India
- Electoral-roll revision
- Inclusion and exclusion
- Due process
- Natural justice
- Electoral participation
A crucial distinction for aspirants is between administrative allegations/claims and judicial findings. The Supreme Court’s comments concern the procedure and notices; they do not themselves establish that voters will be disenfranchised.
4. Elections to 12 Rajya Sabha Seats on October 16
The Election Commission announced elections to 12 Rajya Sabha seats:
- 10 from Uttar Pradesh
- 1 from Uttarakhand
- 1 from West Bengal
The polling is scheduled for October 16, 2026.
The notification will be issued on September 29, with nominations closing on October 6.
Prelims angle
Remember the constitutional distinction:
Lok Sabha → Direct election
Rajya Sabha → Indirect election
Rajya Sabha members representing States are elected by elected members of the respective State Legislative Assemblies through proportional representation by means of the single transferable vote.
The newspaper also notes that the electoral arithmetic could alter the party composition of the Upper House.
II. ECONOMY & AGRICULTURE
5. Maharashtra Women Farmers’ Empowerment Bill
One of today’s most important social-sector developments is Maharashtra’s Women Farmers’ Empowerment Bill, passed in July 2026.
The legislation provides women with independent recognition as farmers irrespective of land ownership through a Woman Farmer Certificate.
This is significant because India’s conventional administrative definition of a farmer has often been linked to land ownership or land records.
The recognition problem
Women participate extensively in agricultural activity but frequently:
- Do not own the land
- Do not appear in land records
- Work as unpaid family labour
- Have limited access to institutional credit
- Are excluded from certain agricultural databases and schemes
The newspaper notes that only around 14% of operational agricultural land holdings were with women according to the 2015–16 Agricultural Census.
Who can be recognised?
The legislation explicitly covers categories such as:
- Landless cultivators
- Landless livestock rearers
- Agricultural labourers
- Plantation labourers
- Pastoralists
Why it matters
The issue illustrates the difference between:
Landowner ≠ Farmer ≠ Agricultural worker
Policy recognition based exclusively on land records can produce a gendered data and welfare-access gap.
The article also suggests integration of the new recognition mechanism with Agri Stack and Farmer IDs.
Mains linkage
Gender + Agriculture + Land rights + Social protection + Digital governance
6. Punjab’s Groundwater Crisis
Punjab’s groundwater extraction rate has reached around 152%, according to the 2025–26 Dynamic Groundwater Assessment cited in the newspaper.
Around 72% of Punjab’s 153 assessment blocks are reportedly in the red zone.
The problem is closely linked to the State’s agricultural production structure.
Why Punjab’s groundwater is under stress
The rice-wheat system was strengthened by:
- Assured procurement
- Minimum Support Price mechanisms
- Subsidised electricity
- Easy groundwater access
- Irrigation-intensive cultivation
The result has been a highly concentrated cropping pattern.
The deeper economic problem
Groundwater depletion creates an unusual distributional effect.
As water tables fall:
Deeper borewells → Higher capital requirement → Greater advantage to wealthier farmers
Smaller farmers may increasingly have to purchase water, transferring resources towards larger landowners.
Way forward
The newspaper highlights the need to:
- Promote crop diversification
- Improve irrigation efficiency
- Reduce incentives for excessive extraction
- Support smallholders
- Encourage collective irrigation infrastructure
- Redirect subsidies towards farmers rather than groundwater consumption alone
This is an excellent GS-III agriculture + environment + subsidy reform topic.
III. SCIENCE & TECHNOLOGY
7. Canal-Top Solar Photovoltaics: Turning Canals into Energy Infrastructure
One of the strongest Science & Technology topics in today’s paper is Canal-Top Photovoltaics (CTPV).
Unlike floating solar panels, which are installed on water bodies, CTPV involves installing solar panels on elevated structures over irrigation canals.
Advantages
1. No additional land requirement
Solar infrastructure can be built over existing canals.
This is particularly important because land acquisition is becoming a constraint for large solar projects.
2. Reduction in evaporation
Solar panels provide shade over the water surface and can reduce water loss through evaporation.
3. Potential efficiency gains
The water below the panels can provide a cooling effect, potentially improving panel performance in hot conditions.
The newspaper cites the 1-MW canal-top solar project at Narmada Canal in Gujarat, commissioned in 2012, as an early Indian example.
Potential
A 2024 assessment cited by the article estimated India’s CTPV and canal-bank solar potential at around 131 GW, subject to technical and geographical conditions.
The States identified as having particularly high potential include:
- Uttar Pradesh
- Bihar
- Karnataka
- Andhra Pradesh
- Punjab
Challenges
- High structural cost
- Maintenance difficulties
- Wind loading
- Canal geometry
- Access for repairs
- Grid connectivity
- Higher cost compared with ground-mounted solar
UPSC takeaway
Floating solar ≠ Canal-top solar
| Floating Solar | Canal-top Solar |
|---|---|
| Panels mounted on floating structures | Panels mounted above canals |
| Uses water bodies | Uses canal infrastructure |
| Requires anchoring systems | Requires elevated structural support |
| Reduces evaporation | Can reduce canal evaporation |
This is a strong GS-III renewable-energy and water-energy nexus topic.
8. AI Safety: Scientists Caution Against “Doomsday” Rhetoric
Experts associated with a UN International Scientific Panel on AI have cautioned against presenting artificial intelligence risks exclusively through apocalyptic scenarios.
The central argument is that AI-risk discussions should distinguish between:
What is scientifically established
and
What is a plausible extrapolation from current evidence.
The International Scientific Panel on AI was created in 2025, with members selected in February 2026, to strengthen scientific understanding of AI and inform UN deliberations.
Why is this important?
AI governance has two simultaneous requirements:
Risk prevention
- Safety
- Misuse
- Autonomous systems
- Misinformation
- Cybersecurity
- Labour disruption
Evidence-based policy
- Risk assessment
- Technical research
- Measurement
- International cooperation
- Avoidance of exaggerated claims
For UPSC, this fits within:
AI governance + emerging technology + ethics + international institutions
The article also raises the important distinction between existential risk and more immediate, measurable AI harms.
IV. ENVIRONMENT
9. Karnataka Assembly Resolution on Western Ghats ESA
The Karnataka Legislative Assembly and Council adopted a resolution asking the Union government to restrict the Ecologically Sensitive Area (ESA) under the Kasturirangan framework to notified forests.
The State has also sought one year to conduct a physical survey.
The latest draft notification reportedly covers approximately:
20,668 sq. km across 10 districts.
Karnataka’s proposed approach would reduce the area to approximately 16,000 sq. km.
Why is the Western Ghats issue important?
The Western Ghats are:
- A global biodiversity hotspot
- Rich in endemic species
- Important for river systems
- A major rainfall-influencing region
- A source of ecosystem services
- Home to large rural populations
The central policy challenge is:
Ecological conservation ↔ Development ↔ Livelihoods ↔ Federalism
The development also illustrates the recurring tension between Union environmental regulation and State-level implementation.
V. INTERNATIONAL RELATIONS
10. India Joins Partnership for Multilateralism (P4M)
India has joined the Partnership for Multilateralism (P4M).
The initiative was originally launched by:
- European Union
- Brazil
- Canada
- Kenya
India became an additional co-sponsor along with Australia and Barbados.
External Affairs Minister S. Jaishankar participated in the first P4M Summit held alongside the 81st UN General Assembly.
India’s broader objective
India has repeatedly advocated reformed multilateralism, arguing that global institutions should better reflect contemporary geopolitical and economic realities.
The P4M discussion focuses on strengthening:
- International cooperation
- International law
- Multilateral institutions
- Transparent decision-making
- UN-centred cooperation
India is also seeking support for its candidature for a UN Security Council non-permanent seat for 2028–29.
Mains linkage
“Reformed multilateralism is essential to address the mismatch between 20th-century institutions and 21st-century realities.”
11. India–Bangladesh: New High Commissioner
Bangladesh’s current Foreign Secretary Asad Alam Siam will become Bangladesh’s next High Commissioner to India.
India has granted the required agrément, paving the way for his appointment.
The appointment comes amid efforts to maintain diplomatic engagement between New Delhi and Dhaka.
UPSC relevance
India–Bangladesh relations involve:
- Neighbourhood First
- Trade
- Connectivity
- River-water issues
- Border management
- Security cooperation
- Migration
- Energy
- Regional connectivity
The development should therefore be understood as part of the broader diplomatic institutional relationship, rather than as an isolated personnel change.
12. India–U.S. Trade Negotiations and Section 301 Investigations
The newspaper reports that an India–U.S. trade agreement may face delays because of U.S. Section 301 investigations involving India and some competing economies.
The report says the issue involves differences in the tariff treatment of India and competitor countries.
A related development is the Lindsey O. Graham Sanctioning Russia and Iran Act, which the newspaper reports as enabling the U.S. executive to impose tariffs of up to 100% on major importers of Russian oil, potentially affecting India and China.
UPSC concepts
This story connects several economic concepts:
MFN treatment
versus
Preferential market access
and
Unilateral trade measures
It also demonstrates how geopolitical considerations increasingly interact with international trade policy.
For UPSC, focus on:
- WTO principles
- Section 301
- Tariff barriers
- Trade diversion
- Energy security
- Strategic autonomy
The newspaper’s report attributes the assessment about the likely delay to a person familiar with the negotiations; it should therefore not be treated as an official announcement of the outcome.
13. Strait of Hormuz and the Global Energy System
The ongoing West Asian conflict continues to have major implications for the Strait of Hormuz.
The newspaper reports that traffic through the strategic maritime corridor has been severely disrupted.
Why Hormuz matters
The Strait connects the:
Persian Gulf ↔ Gulf of Oman ↔ Arabian Sea
It is one of the world’s most important maritime energy chokepoints.
Disruption can affect:
- Crude-oil prices
- LNG supplies
- Shipping insurance
- Freight rates
- India’s import bill
- Inflation
- Current account balance
For India, the issue is especially important because the country is highly dependent on imported crude oil.

VI. ECONOMY & FINANCE
14. RBI Absorbs ₹71,971 Crore Through VRRR
The Reserve Bank of India absorbed ₹71,971 crore from the banking system through an overnight Variable Rate Reverse Repo (VRRR) auction.
The auction was conducted for ₹75,000 crore and received bids for around 96% of the notified amount.
The accepted rate was 5.24%.
What is VRRR?
Under a variable rate reverse repo operation, banks park surplus funds with the RBI for a specified period.
It allows the RBI to manage systemic liquidity.
Why would RBI absorb liquidity?
Excess liquidity can:
- Push short-term interest rates downward
- Increase monetary transmission challenges
- Contribute to demand pressures
- Complicate monetary-policy implementation
The operation therefore forms part of the RBI’s liquidity-management toolkit.
The newspaper reports banking-system liquidity at around ₹4.92 lakh crore surplus as of September 21.
15. India’s First Blue Bond
Sagarmala Finance Corporation is planning India’s first blue bond, according to the report.
The proposed issue is for approximately ₹6 billion, with a greenshoe option of ₹5 billion, through 10-year bonds.
What are blue bonds?
Blue bonds are debt instruments used to finance projects connected with marine and water-related sustainability.
Potential uses include:
- Clean water
- Wastewater treatment
- Recycling
- Sustainable fisheries
- Ocean energy
- Marine conservation
- Sustainable shipping
Green bond vs Blue bond
Green bond → Broad environmental projects
Blue bond → Sustainable ocean/water-related projects
This is a useful financial-instrument question for Prelims.
VII. MINERALS & INDUSTRIAL POLICY
16. “Squatting” on Mining Blocks and India’s Lithium Strategy
The Mines Ministry has raised concerns about mining companies holding acquired mineral blocks without commencing operations within the expected timeframe.
This practice has been described as “squatting”.
Why is this a problem?
Mineral blocks are allocated to facilitate actual resource development.
If production is delayed:
Mineral reserves remain unutilised → Domestic supply remains constrained → Import dependence persists
The Mines Secretary also indicated that India is keeping open the possibility of cooperation in lithium exploration in Mali.
A policy for domestic processing of lithium and nickel is also reportedly being prepared.
Strategic significance
Lithium and nickel are important for:
- Batteries
- Electric vehicles
- Energy storage
- Renewable-energy systems
- Advanced manufacturing
The broader objective is to develop an integrated battery ecosystem rather than merely securing raw materials.
VIII. HEALTH & PHARMACEUTICAL REGULATION
17. Supreme Court Raises Concern Over Cancer-Medicine Pricing
The Supreme Court expressed concern over the pricing of essential cancer medicines after noting an example in which a drug reportedly carried an MRP of ₹27,000 despite being supplied to retailers at around ₹2,700.
The Court questioned whether such a ten-fold difference could be justified.
UPSC significance
The issue raises broader questions about:
- Drug-price regulation
- Essential medicines
- NPPA
- Pharmaceutical supply chains
- Consumer protection
- Public health
- Accessibility of healthcare
The important distinction is between:
MRP → Maximum retail price
and
Trade price → Price at which medicine enters the distribution chain
The Supreme Court’s observations were made during proceedings; they should not be treated as a final determination that every such price difference constitutes unlawful pricing.
18. CDSCO Warns Against Indiscriminate Antibiotic Use
The Central Drugs Standard Control Organisation (CDSCO) has cautioned against indiscriminate or prolonged use of painkillers and antibiotics.
The regulator referred to the regulatory framework under:
- Drugs and Cosmetics Act, 1940
- Drugs Rules, 1945
It advised against self-medication with antibiotics and emphasised that many uncomplicated viral infections do not require antibiotics.
UPSC linkage
This connects to the broader problem of:
Antimicrobial Resistance (AMR)
Unnecessary antibiotic use can increase selective pressure favouring resistant microorganisms.
The topic can be linked to:
- One Health
- Public-health surveillance
- Prescription regulation
- Hospital infection control
- Pharmaceutical stewardship
IX. ADDITIONAL SCIENCE & TECHNOLOGY CONCEPT
19. From Springs to Superconductivity: The Physics of Elasticity
Today’s The Hindu Science page provides an interesting conceptual explanation of spring mechanics, elasticity, electromagnetic interactions and superconductivity.
A spring stores mechanical potential energy when compressed.
The relationship between force and displacement is expressed by Hooke’s Law:
F = −kx
where:
- F = restoring force
- k = spring constant
- x = displacement
The article then connects microscopic atomic interactions to elastic behaviour.
At very low temperatures, certain materials can exhibit superconductivity, where electrical resistance falls to zero.
The article explains the role of Cooper pairs in conventional superconductivity.
UPSC relevance
This is useful for conceptual Science & Technology preparation:
Elasticity → Atomic interactions → Lattice vibrations → Electron interactions → Cooper pairs → Superconductivity
X. CULTURE & HISTORY
20. Battle of Haifa: History, Memory and India–Israel Relations
An important analytical article revisits the Battle of Haifa of 1918, fought during the final phase of the First World War.
Indian cavalry units, including the Jodhpur, Mysore and Hyderabad Lancers, participated in the campaign.
The article explores how the battle has acquired different meanings for:
- India
- Israel
- Palestinians
- Historians
UPSC significance
The episode can be connected to:
- Indian participation in World War I
- Colonial military history
- India’s global military legacy
- India–Israel relations
- Palestine question
- Politics of historical memory
The article particularly highlights the tension between recognising the courage of Indian soldiers and examining the imperial political context in which they fought.

Essay
The newspaper provides several potential essay themes:
“A law that does not clearly define an offence cannot produce predictable justice.”
“Recognition is the first step towards inclusion, but recognition without access is incomplete empowerment.”
“India’s energy transition is as much a land and water challenge as it is an energy challenge.”
“Historical memory becomes meaningful when it accommodates multiple perspectives.”
