From UPSC perspective, the following things are important :
Mains level: Private Property; DPSP;
Why in the News?
A 9-judge Constitution Bench of the Supreme Court, in a majority judgment (8:1), held that not every private resource can be considered a ‘material resource of the community’ to be used by the government to serve the ‘common good’ under Article 39(b).
- This overturns the earlier interpretation formed in 1977 that has been followed by the Supreme Court till 1997.
What are Constitutional Provisions?
- Part IV of the Constitution contains the Directive Principles of State Policy (DPSP) where government should strive to achieve social and economic justice in our society.
- Article 39(b) in Part IV provides that ‘ownership and control of material resources of the community are so distributed as best to subserve the common good.’
- Articles 19(1)(f) and 31 originally guaranteed right to property and compensation for acquisition as a Fundamental Right respectively.
- Article 31C that was added through the 25th amendment in 1971, provided an exception that laws made to fulfil the principles under Articles 39(b) and (c) shall not be void on the ground that it violated Fundamental Rights including right to property.
- In the Kesavananda Bharati case (1973), a 13-judge Bench of the Supreme Court upheld the validity of Article 31C but made it subject to judicial review.
- In 1978, the right to property was omitted from Fundamental Rights and made a constitutional right under Article 300A.
- Any law to acquire private property by the government should only be for a public purpose with adequate compensation meted out.
What were earlier judgments?
- In the State of Karnataka vs. Ranganatha Reddy (1977) case, the Supreme Court upheld a law nationalizing private bus services, with Justice V.R. Krishna Iyer interpreting “material resource of the community” in Article 39(b) to include all national wealth.
- This minority opinion influenced the Sanjeev Coke Manufacturing Company vs. Bharat Coking Coal Limited (1982) case, which also supported nationalization, and was referenced in Mafatlal Industries Limited vs. Union of India (1996).
What is the current ruling?
- The SC recently ruled in the Property Owners Association vs. State of Maharashtra case that not all privately owned properties qualify as “material resources of the community” under Article 39(b).
- A 9 judge bench, stated that only certain properties, based on their nature and impact on public welfare, can be considered for state acquisition to serve the common good.
- This decision marks a shift from earlier interpretations that emphasized that individual property rights are protected and not every private asset can be appropriated by the state.
- The ruling also noted that the term “distribution” in Article 39(b) includes both state acquisition and redistribution to private entities when it benefits the community.
|
What criteria should determine if a privately owned resource qualifies as a ‘material resource of the community’?
- Purpose and Public Utility: Privately owned resources may be classified as “material resources of the community” if they are essential for societal welfare, addressing collective needs, or fulfilling significant public purposes, such as energy, water, or land critical for infrastructure.
- Proportionality and Fairness: The court emphasized that any state action must be proportional, balancing public benefit with the impact on private owners.
- Economic Impact and Control: Resources that substantially impact the national economy or are crucial for maintaining societal equity (such as natural resources) may be considered community resources, but this does not apply to general private property.
How does this ruling impact the balance between individual property rights and the state’s ability to intervene for public welfare?
- This ruling reinforces individual property rights, clarifying that private property cannot be arbitrarily acquired under the guise of benefiting society. The state must justify the acquisition based on substantial, verifiable public welfare needs.
- Limitations on State Power: By rejecting an expansive interpretation of Article 39(b), the court limits state power, ensuring that only properties directly tied to public interest and welfare fall under this category.
What are the potential economic implications of this ruling in India?
- Investment Climate: This ruling strengthens protections for private property, likely improving investor confidence by assuring that property rights are safeguarded from excessive state intervention.
- Economic Development and Social Equity: By narrowing the scope of Article 39(b), the ruling limits redistributive policies to sectors where public welfare is a clear priority, allowing economic resources to be distributed in a manner that considers social equity while respecting individual rights.
- Real Estate and Industrial Sectors: The ruling could positively affect sectors with high-value assets, such as real estate and industry, as businesses will have greater certainty regarding property ownership and security.
How might this decision influence future legal interpretations and legislative actions?
- Refined Scope for Article 39(b) Applications: Future legislation under Article 39(b) must specifically justify how resources qualify as “material resources of the community,” likely limiting nationalization or acquisition to specific, strategically important sectors.
- Increased Judicial Scrutiny on Property Rights: Courts are likely to more critically evaluate state actions that aim to redistribute private property, requiring robust evidence of public interest and alignment with constitutional principles.
- Potential for Policy Revisions: Laws that invoke Article 39(b) and related provisions may need to be reviewed to ensure they comply with this interpretation, leading to a more nuanced application of public welfare policies.
Way forward:
- Establish Clear Guidelines for Public Interest Acquisition: The government should define transparent criteria for categorizing “material resources of the community,” ensuring acquisitions serve substantial public welfare needs and align with societal priorities, especially in areas like infrastructure and essential services.
- Strengthen Judicial and Legislative Safeguards: Introduce legal safeguards to protect individual property rights, allowing courts to rigorously assess state actions on property acquisition, ensuring proportionality, fairness, and adherence to constitutional principles.

From UPSC perspective, the following things are important :
Mains level: Issues related to vigilantism;
Why in the News?
On July 30, Uttar Pradesh toughened its 2021 anti-conversion law, increasing the maximum sentence to life imprisonment, tightening bail conditions, and expanding “illegal conversion” to include promises of marriage and trafficking.
How do current laws facilitate vigilante actions under the guise of protecting societal values?
- Expansion of Complainant Scope: The amended law allows any individual, regardless of personal involvement or direct impact, to lodge complaints about alleged unlawful conversions.
- Broad Interpretation of “Public Interest”: By permitting police officers and unrelated third parties to file FIRs, the law can be exploited to initiate cases that target religious minorities or interfaith couples, framing these as societal threats.
- Legal Ambiguity and Arbitrary Application: The inconsistent interpretations of “aggrieved person” under Section 4 by different courts have led to uncertainty.
- This ambiguity has allowed authorities and vigilantes to target groups and individuals selectively, often with little or no evidence of wrongdoing, undermining personal freedoms and due process.
- Reduced Threshold for Evidence: By widening the scope of what constitutes “illegal conversion” to include vague terms like “promise of marriage,” the law can easily be manipulated.
- This opens the door for complaints based on assumptions or suspicions, rather than clear, proven instances of forced conversion.
What measures can be implemented to ensure effective enforcement of laws against mob violence and vigilantism?
- Strict Definitions and Limits on Complainants: Restricting who can file complaints to genuinely aggrieved parties—directly affected individuals or close relatives—could help prevent misuse by third-party vigilante actors.
- Accountability Mechanisms for Law Enforcement: Police officers who file unfounded FIRs based on ideologically motivated complaints should face accountability measures.
- Disciplinary action or judicial oversight in cases of misuse would help discourage officers from acting on non-substantial complaints.
- Enhanced Legal Protections for Victims of Vigilantism: Establishing a separate body to investigate and prosecute cases of mob violence and vigilante actions can protect targeted groups.
- Promotion of Public Awareness and Legal Literacy: Initiatives to raise awareness about individual rights and legal processes can empower citizens to resist unlawful actions by vigilantes.
What role do societal perception and political influence play in the rise of vigilantism?
- Ideological Justifications for Vigilantism: Laws like the anti-conversion amendment are often framed as measures to protect cultural or religious values, creating a narrative that justifies vigilante actions as morally and socially acceptable.
- Political Endorsement and Implicit Encouragement: When political entities endorse such laws or publicly support vigilante actions, they create a permissive environment for vigilantism.
- Media Influence and Public Perception: Coverage of interfaith relationships or religious conversions as “threats” to societal harmony often fuels public support for vigilante actions.
- Sensationalist media narratives contribute to a heightened perception of certain groups as “others,” justifying vigilantism as a form of social correction.
- Inadequate Legal Deterrence: Weak penalties for mob violence or leniency in prosecuting vigilantes reinforce the perception that vigilantism will be tolerated, especially if aligned with popular or politically endorsed views.
Way forward:
- Enact Clearer Legal Boundaries and Protections: Define strict limits on who can file complaints under anti-conversion laws, ensuring only directly affected individuals or close family members can do so.
- Strengthen Public Awareness and Judicial Oversight: Promote legal literacy campaigns to educate citizens on their rights and the dangers of vigilante actions, and establish judicial oversight for cases involving mob violence and vigilantism to ensure accountability and protection for targeted groups.

From UPSC perspective, the following things are important :
Mains level: Significance of Aadhaar biometric data;
Why in the News?
The Unique Identification Authority of India (UIDAI) enforces strict regulations on data disclosure to safeguard individuals’ privacy and prevent misuse of personal information. Under normal circumstances, the police cannot access the demographic or biometric details stored in the Aadhaar database.
What are the legal limitations of using Aadhaar biometric data for forensic purposes?
- Stringent Privacy Protections: The Aadhaar Act mandates strict protection of personal data, especially biometrics.
- Sections 29(1) and 33(1) prevent sharing of core biometric data (fingerprints and iris scans) with third parties, even law enforcement, barring limited situations.
- Court Order Requirement: Section 33(1) allows disclosure of certain demographic data upon the order of a High Court or above, but core biometrics are strictly protected and cannot be shared, creating limitations for police investigations involving unidentified bodies.
- Forensic Investigative Gaps: Police databases are often limited to individuals with criminal records, restricting the ability to identify deceased persons through fingerprints.
- Without access to a comprehensive Aadhaar database, identification processes for unknown deceased individuals become more challenging and time-consuming.
How can the balance between privacy rights and forensic needs be achieved?
- Right to Privacy vs. Right to Dignity: Balancing the fundamental right to privacy with the right to a dignified life and death is essential, especially in cases where access to biometric data can help identify unknown bodies.
- Controlled Access Mechanisms: Limited, case-specific access, such as requiring a judicial magistrate’s order (rather than a High Court order), can allow law enforcement to use Aadhaar biometrics in cases involving unidentified bodies, reducing the burden on higher courts while preserving privacy safeguards.
- Transparent Oversight: Any mechanism permitting Aadhaar data usage for forensics should include robust oversight, including logging access and stringent penalties for misuse, ensuring that access is restricted to genuinely necessary cases.
What technological and procedural changes are necessary to facilitate the use of Aadhaar data in forensics?
- Advanced Identification Algorithms: Introducing algorithms similar to the U.S. Deceased Persons Identification (DPI) system would enable more accurate and efficient matching of deceased persons’ fingerprints with larger databases.
- Digitization of Police Records: Digitizing state-level fingerprint databases would allow faster cross-referencing and aid forensic investigations, creating a more accessible identification system even without Aadhaar.
- Secure Data Access Channels: Secure and encrypted channels specifically for forensic use, with limited access, could protect the data while allowing controlled use.
- Specific Legislative Frameworks: There should be new amendments that could clarify circumstances under which biometric data can be accessed for deceased individuals, distinguishing these cases from broader data privacy concerns.
Way forward:
- Amend Legal Framework for Controlled Access: Need to introduce specific legislative amendments allowing limited, case-specific access to Aadhaar biometrics for forensic purposes in cases involving unidentified deceased individuals, with strict judicial oversight to maintain privacy protections.
- Establish Secure Access Protocols and Oversight: Need to implement secure, encrypted access channels and enforce strict oversight mechanisms, including access logging and penalties for misuse, ensuring biometric data is accessed only when absolutely necessary for forensic identification.

From UPSC perspective, the following things are important :
Prelims level: Sun’s Rotation
Why in the News?
Indian astronomers at the Kodaikanal Solar Observatory (KSO) have achieved a groundbreaking feat by mapping, for the first time, the variation in the Sun’s rotation speed from its equator to its poles.
Sun’s Rotation: Key Facts
- Unlike a solid body, the Sun exhibits differential rotation, meaning different parts of the Sun rotate at different speeds.
- The rotation speed varies depending on latitude, with faster rotation near the equator and slower rotation toward the poles.
- This variation is primarily due to the Sun’s composition of gaseous plasma rather than solid material.
Rotation Period Variation by Latitude:
- Equatorial Regions: The rotation period at the equator is the fastest, around 24.47 days (sidereal rotation).
- Sunspot Zones (about 16 degrees latitude): Rotation slows slightly, with a period of about 27.3 days.
- Higher Latitudes (up to 75 degrees): Rotation slows significantly; for example, at 75 degrees latitude, the rotation period is about 33.4 days.
- Poles: The slowest rotation occurs at the poles, with a period around 31.1 days.
Sidereal vs. Synodic Rotation Periods:
- Sidereal Rotation Period: The time taken for the Sun to complete one full rotation relative to distant stars. It varies by latitude, from 24.47 days at the equator to around 33.4 days at higher latitudes.
- Synodic Rotation Period: This is the time for a fixed feature on the Sun to appear in the same position when observed from Earth. It is longer than the sidereal period due to Earth’s own movement around the Sun, averaging around 26.24 days.
Why Differential Rotation Occur?
- Gaseous Plasma Composition: The Sun is composed of plasma—a hot, ionized state of matter—which allows its different regions to rotate at different speeds.
- Convective Zone Dynamics: The outer convective layer of the Sun contributes to differential rotation. Plasma circulates, rising and sinking, which influences the rotational speed at different latitudes.
Scientific Implications
- Solar Dynamo Theory: The differential rotation of the Sun is central to theories about the solar dynamo—the process that generates the Sun’s magnetic field.
- Mystery of Differential Rotation: Despite extensive research, the exact mechanism behind the Sun’s differential rotation remains an active area of investigation in solar physics.

From UPSC perspective, the following things are important :
Mains level: Issues related to Rural Governance;
Why in the News?
From 2019-20 to 2023-24, India’s economy grew at 4.6% annually, with the farm sector at 4.2%, yet rural wages remain stagnant.
Disparity between Rural Wages and Economic Growth:
- Divergent Growth Trends: While the Indian economy has experienced significant GDP growth (averaging 4.6% annually from 2019-20 to 2023-24), rural wages have stagnated, with real agricultural wages showing minimal growth and often negative real wage growth due to rising inflation.
- Labor Supply Dynamics: The surge in female Labor Force Participation Rates (LFPR) in rural areas has increased the overall labor supply, exerting downward pressure on wages as more workers compete for the same or fewer jobs, primarily in low-productivity agricultural sectors.
- Capital-Intensive Growth: Economic growth has become increasingly capital-intensive and labor-saving, leading to a disproportionate share of income going to capital rather than labour.
- This trend results in fewer job opportunities in high-paying sectors, further exacerbating the stagnation of rural wages.
|
What are the major factors behind the Stagnant Rural Wages?
- Increased Female Labour Force Participation (Surplus of Labour): The rural female Labour Force Participation Rate (LFPR) has seen a sharp rise, particularly due to government initiatives that have freed up women’s time for outside employment.
- However, this has led to a significant increase in the overall rural workforce, causing a surplus of labor that exerts downward pressure on wages.
- Majority of choosing Agricultural Employment: Although more women are entering the labour force, the majority are finding employment in agriculture rather than in higher-paying non-farm sectors.
- This results in a surplus of workers in an already low-productivity sector, which suppresses wages further.
- Capital-Intensive Economic Growth: The Indian economy’s growth has increasingly come from capital-intensive sectors that require fewer workers.
- Consequently, the share of income generated is shifting from labour (wages) to capital (profits). This trend limits demand for rural labour, leading to wage stagnation.
- Low Demand for Non-Agricultural Labor: Wage growth in rural non-agricultural sectors has been even weaker, with real wages declining. This reflects limited job opportunities outside of agriculture, partly due to low demand for labour in industries that are more capital-intensive.
What are the steps taken by Govt to address the issue of Low Rural Wages?
- Income Transfer Schemes: Both central and state governments have introduced various income transfer schemes, like Pradhan Mantri Kisan Samman Nidhi (PM-KISAN) which provides an annual income support of Rs 6,000 to farmer households in rural areas.
- Many states have launched income-support schemes specifically for women, such as Maharashtra’s Ladki Bahin Yojana, which provides Rs 1,500 per month to women from low-income households.
- Employment Generation Programs: Schemes like the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) provide a safety net by guaranteeing 100 days of wage employment for rural households.
- The government has also promoted rural entrepreneurship through initiatives like the Mudra Yojana, which offers micro-loans to rural businesses and enhance employment opportunities.
- Skill Development Initiatives: The government has been investing in rural skill development programs to promote employability in non-farm sectors.
- Programs under schemes like the Deen Dayal Upadhyaya Grameen Kaushalya Yojana (DDU-GKY) focus on upskilling rural youth and women to enable them to find better-paying, non-agricultural employment.
- Rural Infrastructure Development: Initiatives to build rural infrastructure, such as the Pradhan Mantri Gram Sadak Yojana (PMGSY), create temporary employment in construction and improve access to jobs, markets, and services.
|
Way forward:
- Diversification of Employment Opportunities: Enhancing support for non-agricultural sectors through targeted investments in skill development, vocational training, and entrepreneurship programs can create diverse job opportunities.
- Strengthening Agricultural Productivity: Implementing policies that focus on modernizing agricultural practices and improving productivity can increase the income of rural labourers.

Dedicated Freight Corridors (DFCs) are specialized railway tracks for freight transportation, designed to improve efficiency with faster, high-capacity trains like double-stack containers and heavy-haul freight trains.
What is the Present Status?
- India has two main DFCs:
- Eastern DFC (EDFC): Spanning 1,337 km from Sonnagar (Bihar) to Sahnewal (Punjab). The EDFC is operational and includes feeder routes connecting coal mines and thermal plants.
- Western DFC (WDFC): Extends 1,506 km from Jawaharlal Nehru Port (Mumbai) to Dadri (Uttar Pradesh). The WDFC is 93% complete, serving major ports in Gujarat. Full completion is expected by December 2025.
- As of March 31, 2024, the project has incurred costs of ₹94,091 crore, excluding land acquisition.
|
What does the Australian varsity study say?
- Conducted by the University of New South Wales, this study used a Computable General Equilibrium model to assess the WDFC’s impact, specifically from FY 2019–20.
- The study’s findings include:
- Reduced freight costs and travel times have decreased commodity prices by up to 0.5%.
- The DFCs contributed to a 2.94% increase in Indian Railways’ revenue between FY 2022–23 and FY 2018–19.
- Western regions gained significantly from reduced freight costs, which had a “social-equalizing effect,” benefiting states with lower per capita GDP.
- Published in Elsevier, the study integrated freight costs, industry inputs, population data, and rail and road data.
What economic benefits do Dedicated Freight Corridors (DFCs) bring to India?
- Improved Supply Chains: DFCs provide faster, efficient transit for freight, enhancing the supply chain for industries and logistics providers.
- Cost Savings: Reduction in freight transport costs lowers overall logistics expenses, which can lead to price reductions for consumers.
- Revenue Growth for Railways: DFCs have directly contributed to revenue increases, supporting the Railways’ finances.
- Increased Freight Share: The corridors are key to meeting the National Rail Plan’s target of achieving a 45% rail share in freight by 2030.
- Exports and Imports: Faster, dedicated freight routes boost export-import activities, as DFCs support port connectivity, particularly in the West.
How do DFCs enhance the overall logistics and transportation infrastructure in India?
- Decongested Rail Network: By shifting freight traffic off the main passenger routes (e.g., the Golden Quadrilateral), DFCs alleviate congestion, improving both freight and passenger rail reliability.
- Regional Development: States along the DFC routes experience increased industrial activity due to improved logistics support, which can enhance local economies and job creation.
- Future Corridors: Plans are underway for four additional corridors (East Coast, East-West I & II, North-South) to further expand the freight network, enhancing connectivity across the country.
Current Operational Status and Future Outlook
- As of now, 325 trains run daily on the DFCs, which is a 60% increase from the previous year.
- DFC trains are faster, safer, and capable of carrying heavier loads, contributing to over 10% of Indian Railways’ total freight operations.
- DFCCIL is conducting further research on DFCs’ economic impact, with results expected soon, which will provide deeper insights into their long-term contributions to India’s economic growth.
|
Challenges related to the development of DFC:
- Land Acquisition Delays: Acquiring over 8,800 hectares, often privately owned and developed land, has caused setbacks, with disputes and legal cases prolonging the process.
- Escalating Costs: Project costs have surged significantly, with Japan International Cooperation Agency (JBIC) noting that expenses have nearly doubled, raising concerns about financial viability and potential investor reluctance.
- Technology Disputes: Differences over locomotive technology—diesel versus electric—pose delays, as stakeholders like Indian Railways and JBIC debate environmentally friendly solutions.
- Utility and Infrastructure Challenges: Shifting utilities (power lines, water pipes) and constructing road overbridges and under-bridges add logistical complexities.
- Funding and Financial Management: Reliance on external funding and the need for efficient resource management impact project timelines and execution stability.
Way Forward:
- Streamlined Land Acquisition and Cost Management: Need to implement a centralized framework for faster land acquisition and cost oversight to mitigate delays and prevent cost escalations, ensuring project feasibility and investor confidence.
- Technological and Funding Consensus: Need to establish clear technology standards (e.g., electric locomotives) for environmental benefits and secure diversified funding sources to reduce dependence on external financing, enabling timely completion and sustainable operations.

From UPSC perspective, the following things are important :
Prelims level: Black Hole Triple and its formation
Why in the News?
Scientists have discovered a “black hole triple” in space, marking the first time such a system has been identified.
Black Hole Triple: What does it mean?
- Many black holes are found in binary systems with another star or black hole.
- This triple system includes two stars orbiting a black hole:
- The nearer star orbits the black hole every 6.5 days.
- The distant star orbits approximately every 70,000 years.
- The system, located in the constellation Cygnus, features V404 Cygni, one of the oldest black holes known, which is nine times larger than the Sun.
- It is 8,000 light years away from Earth.
What is a Black Hole?
- A black hole is a space region with such strong gravity that no light or matter can escape.
- Most black holes form from supernova explosions—the death of massive stars.
- This triple system suggests an alternative, less violent formation process.
|
How was it discovered?
- Researchers from Caltech and MIT discovered the system while reviewing astronomical data from telescopes.
- They described the stars as being gravitationally bound, indicating they form a triple system.
- It is believed that V404 Cygni did not form through a supernova explosion, which typically ejects outer stars.
- Instead, it likely formed through direct collapse: the star collapsed inward without exploding.
- Known as a “failed supernova”, this process causes an implosion without expelling matter, leading to a gentler black hole formation.
Future of the Triple System
- The triple system may not remain as such, as V404 Cygni is consuming the nearby star.
- This discovery suggests that some existing binary systems may have originally been triple systems, where the black hole later consumed one of its members.

Prelims level: Glacial Lakes
Why in the News?
Since 1977, the South Lhonak Lake, a glacial lake in Sikkim has expanded significantly, growing from 17 hectares to 167 hectares by 2023.
Formation of Glacial Lakes:
- When a glacier melts and retreats, the hollow left behind often fills with water, creating a glacial lake.
- The rocky moraine at the glacier’s end can act as a natural dam, holding the water to form the lake.
- Glacial lakes act as hydrological buffers, regulating water flow from melting ice, which can sometimes pose challenges to downstream communities.
- Glacial lakes often have a vivid blue color, similar to swimming pools, due to the scattering of light by fine rock particles (rock flour) in the water.
- There are several types of glacial lakes, each formed by specific processes and glacier dynamics:
-
- Moraine-Dammed Lakes: Formed when moraine debris piles up at the end of a glacier and traps meltwater behind it. These are common and pose risks of outburst flooding.
- Kettle Lakes: This was created when a chunk of glacier ice is buried in the moraine and eventually melts, leaving a depression filled with water.
- Cirque Lakes: Formed in circular basins (cirques) carved by glaciers at high elevations. These lakes are often small and located at the glacier’s original head.
- Pro-glacial Lakes: Situated in front of the glacier, between the ice and the moraine dam. These lakes are sometimes formed when the glacier’s snout melts and deposits water in the valley.
- Tarn Lakes: Formed in depressions left behind in the cirques or basins after the glacier has completely melted.
|
Major Glacial Lakes in India
India’s Himalayan region is home to numerous glacial lakes, each with unique characteristics:
- Gurudongmar Lake (Sikkim): One of the highest lakes in the world at 5,430 meters above sea level, fed by glacial melt and known for its religious significance.
