[UPSC 2022] Discuss global warming and mention its effects on the global climate. Explain the control measures to bring down the level of greenhouse gases which cause global warming, in the light of the Kyoto Protocol, 1997.
Linkage: SO2 as “one of the major greenhouse gases that cause global warming”. Flue Gas Desulphurisation (FGD) units are designed specifically to remove SO2 emissions from the combustion of fossil fuels. Therefore, FGD units serve as a direct “control measure to bring down the level of greenhouse gases” as addressed by the question.
Mentor’s Comment: India’s top science advisory group has suggested ending the 2015 rule that made it compulsory for all coal-based power plants to install Flue Gas Desulphurisation (FGD) units. This has raised serious concerns because FGDs are key to reducing sulphur dioxide (SO₂) pollution, which causes 15% of India’s PM2.5 levels and leads to breathing problems, environmental damage, and climate change. Although installing FGDs is expensive (₹1.2 crore per MW), experts warn that dropping the plan could harm public health and clean air efforts. Worryingly, only 39 of 537 plants have installed FGDs, and deadlines keep getting pushed back.
Today’s editorial focuses on the analysis of the installation of the Flue Gas Desulphurisation (FGD) units in a thermal power plant. This content is very relevant to GS Paper III (Environment, Science and Technology) Mains.
_
Let’s learn!
Why in the News?
A group of experts, led by Principal Scientific Advisor Ajay Sood, has recently suggested that India should cancel the 10-year-old rule that requires all coal-based thermal power plants to install Flue Gas Desulphurisation (FGD) units.
Why India should cancel the 10-Year-Old Rule (2015 FGD Mandate)?
High Installation Cost Burden: Installing FGD units costs around ₹1.2 crore per MW, which can significantly raise power generation costs and electricity tariffs. Eg: For 97,000 MW of new capacity, the cost would be about ₹97,000 crore, making power less affordable.
Delayed and Poor Implementation: Despite the 2015 rule, compliance has been dismal—only 39 out of 537 plants had FGDs installed by 2025. Eg: Repeated deadline extensions (up to 2029) show lack of feasibility and institutional capacity.
Limited Local Air Quality Impact in Some Areas: In certain regions, the contribution of SO₂ emissions from TPPs to PM2.5 levels is relatively small. Eg: In Delhi, most air pollution comes from other sources like vehicles and construction, so FGDs at distant plants may offer minimal benefit.
What is a Flue Gas Desulphurisation (FGD) unit?
FGD units are devices used in coal-fired thermal power plants (TPPs) to remove sulphur dioxide (SO₂) from flue gas. Flue gas is a byproduct of burning fossil fuels and contains pollutants like SO₂, CO₂, NOx, and particulate matter.
Three common FGD technologies:
Dry sorbent injection (adds powdered limestone to flue gas).
Wet limestone treatment (reacts SO₂ with limestone slurry to form gypsum).
Sea water scrubbing (used near coastal areas).
How does it reduce SO₂ emissions from thermal power plants?
Chemical Neutralisation Reaction: FGD units use alkaline substances like limestone or lime to react with acidic SO₂ in flue gas, converting it into stable, non-toxic compounds. Eg: In wet limestone FGD, SO₂ reacts with limestone slurry to form gypsum (CaSO₄·2H₂O), a harmless industrial byproduct.
Efficient Scrubbing Techniques: Technologies like wet scrubbers or dry sorbent injection physically remove SO₂ from exhaust gases before release into the atmosphere. Eg:Dry sorbent injection sprays powdered lime into the flue gas stream, which binds with SO₂ and is later captured by filters.
Controlled Emission Discharge: FGD ensures that the treated flue gas released into the environment has significantly lower SO₂ levels, complying with environmental norms. Eg: Power plants near coasts use sea water FGD, where sea water absorbs SO₂ and is then treated before being discharged safely.
Why are SO₂ emissions harmful?
Respiratory and Health Issues: Sulphur dioxide (SO₂) irritates the respiratory system, causing problems like asthma, bronchitis, and lung damage, especially in children and the elderly. Eg: Studies in urban industrial areas show a direct link between SO₂ exposure and increased hospital admissions for respiratory illnesses.
Formation of Secondary Particulate Matter (PM2.5): SO₂ reacts in the atmosphere to form fine particulate matter (PM2.5), which can penetrate deep into lungs and enter the bloodstream, posing serious health risks. Eg: According to studies, 80% of PM2.5 from coal combustion is due to secondary particles formed from SO₂.
Contribution to Acid Rain: SO₂ combines with water vapor in the atmosphere to form sulphuric acid, leading to acid rain that damages soil, crops, forests, and aquatic ecosystems. Eg: Regions near coal-fired plants have reported acidic lakes and damaged crops due to acid rain deposition.
Environmental Degradation: High SO₂ levels can corrode buildings, especially monuments made of limestone or marble, and degrade overall air and water quality. Eg: The Taj Mahal has shown signs of yellowing, partly attributed to SO₂-related pollution.
Climate and Visibility Impact: Though SO₂ itself is not a greenhouse gas, it leads to formation of aerosols, affecting cloud formation, reducing visibility, and causing climate imbalance. Eg: In industrial belts, hazy skies and temperature variations are linked to SO₂-derived aerosols.
What is the status of FGD installation in India (2025)?
Low Overall Commissioning: Only about 39 out of 537 thermal power plant units (≈ 19,430 MW capacity) have commissioned FGD systems, representing ~11% of the total required capacity. Eg: Just 13 out of 35 units within 300 km of Delhi have installed FGDs, showing slow progress in high-pollution zones.
Stalled Projects and Delays: Contracts have been awarded for about 238 units (~105,200 MW), and 139 units (~42,847 MW) are still in the tendering stage, but many projects remain stalled. Eg: Some plants, especially near Delhi, may take up to 36 months to complete FGD installation due to regulatory and logistical hurdles.
Repeated Deadline Extensions: Compliance deadlines have been extended multiple times: from 2017 → 2024 → 2026–2029, depending on the location and plant category. Eg: The Ministry of Environment has pushed back deadlines for thermal plants in Delhi NCR without strict justification, raising concerns about enforcement.
Way forward:
Prioritised FGD Installation: Expedite FGD implementation in high-emission and densely populated zones to balance cost and health impact.
Policy and Financial Support: Provide targeted subsidies or incentives to TPPs and integrate FGD costs into long-term tariff planning for smoother adoption.
The fire on MV Wan Hai 503 near Kannur exposed India’s weak maritime safety. With over 140 hazardous containers onboard, it posed a major risk during the monsoon, threatening the environment and lives.
What are the major types of peacetime maritime accidents faced by the Indian coast?
Sinking of merchant ships – leads to cargo loss, traffic disruption, and environmental damage.
Fire onboard vessels – threatens coastal life, property, and marine ecology.
Oil spills – have long-lasting environmental impacts and are difficult to contain.
Why was the MV Wan Hai 503 incident a significant maritime safety challenge?
Presence of Hazardous Cargo: Over 140 of the 1,754 containers onboard contained hazardous materials, posing a high risk of toxic release and chemical explosions. Eg: Multiple colors of smoke (brown, white, grey, black) indicated different substances burning simultaneously.
Proximity to Coastline During Fire: The ship began drifting dangerously toward the Indian coast near Azhikkal, Kerala, during monsoon rough seas, increasing the threat of coastal disaster. Eg: The tow rope initially snapped under pressure, risking further drift and collision with the shore.
Complexity of Fire-Fighting and Towing: Fire-fighting was complicated by weather conditions and ship instability, requiring precise coordination. Eg: An Indian Navy helicopter had to airdrop a salvage team to pass a steel wire rope for safe towing to deeper waters.
Multi-Agency Emergency Response Needed: The incident required rapid coordination between the Indian Navy, Coast Guard, and the ship owner’s team using tugs. Eg: The ship was finally stabilized 45 nautical miles offshore, where the water depth was nearly one kilometre, minimizing risk to coastal areas.
How did Indian agencies respond to the fire on MV Wan Hai 503?
Rapidfirefighting effortsamid adverse conditions: The Indian Coast Guard initiated firefighting operations despite rough seas caused by the monsoon. Eg:Firefighting continued while the ship drifted dangerously toward the Kerala coast, with thick smoke from burning hazardous cargo.
Coordinatedaerial and naval action: The Indian Navy deployed a helicopter to airdrop a salvage team onto the ship and deliver a steel wire rope to secure it. Eg: The steel rope enabled safe towing after the initial tow rope snapped due to tension and sea conditions.
Strategictowing and risk mitigation: Indian agencies, in coordination with the ship owner’s agents and tugboats, towed the vessel 45 nautical milesaway from the coast to prevent environmental and coastal damage. Eg: The vessel was moved to deeper waters (1 km depth) to minimize the impact of any further explosion or sinking.
Why are gas-carrying and oil-laden ships considered severe fire and explosion hazards?
High flammability of cargo: Gas and crude oil are highly combustible, making these ships extremely prone to fires and explosions if containment fails. Eg: Even a minor spark can ignite vapours from gas or oil, causing catastrophic fires onboard.
Large volume of hazardous material: These vessels carry enormous quantities of flammable substances, which amplify the scale of damage during accidents. Eg: The New Diamond VLCC was carrying 2,70,000 tonnes of crude oil when it caught fire off Colombo in 2020.
Critical maritime chokepoint risks: Accidents involving such vessels at strategic locations like the Suez Canal or Strait of Malacca can disrupt global trade and cause widespread damage. Eg: A gas carrier explosion at a maritime chokepoint could halt international shipping routes, impacting global supply chains.
What are the key areas India needs to strengthen in maritime fire-fighting and salvage operations? (Way forward)
Rapid Salvage Capability: India must improve its ability for quick salvage of sinking or damaged vessels to prevent cargo loss, environmental damage, and navigation disruption. Eg: During the MV Wan Hai 503 incident, timely towing by the Indian Navy helped avert a coastal disaster, but highlighted the need for faster salvage deployment.
Multi-agency Coordination: Effective response to maritime emergencies requires seamless coordination among the Coast Guard, Navy, port authorities, and private salvage firms. Eg: The successful control of the New Diamond VLCC fire involved joint efforts from Indian and Sri Lankan naval forces.
Advanced Fire-fighting Infrastructure: India needs to upgrade fire-fighting equipment on patrol vessels and at key ports, especially for handling hazardous cargo and oil/gas fires. Eg: The Coast Guard’s patrol vessels are now fitted with basic fire-fighting systems, but large-scale fires require specialised ships and foam-based suppression systems.
Mains PYQ:
[UPSC 2023] What are the ways in which oil pollution affects the marine ecosystem? In what way is oil pollution particularly harmful for a country like India?
Linkage: Maritime Accident Response” explicitly talks about the “oil spills” as one of the three major peacetime maritime accidents that the Indian coast needs protection against. It also states that oil is a “more severe fire hazard” than hazardous cargo, especially in the context of gas-carrying merchant ships. This question directly addresses the environmental and national impact of oil pollution, which is a significant aspect of maritime accidents and firefighting efforts.
The tragic aircraft accident in Ahmedabad on June 12, 2025, has once again thrown a spotlight on India’s deeply flawed aviation accident investigation system.
Why is the AAIB’s independence in question despite being a statutory body?
Operational Control by MoCA: Although the AAIB is technically autonomous, it functions under the Ministry of Civil Aviation (MoCA), which also regulates airlines through the Directorate General of Civil Aviation (DGCA). Eg: In the Air India AI171 crash (2025), both the investigation and regulation were under MoCA’s control, raising concerns of bias and lack of transparency.
Leadership Appointments by the Same Authority: The MoCA appoints the heads of both the DGCA and the AAIB, undermining the bureau’s credibility as an independent investigative body. Eg: This centralized appointment structure is unlike the railway sector, where investigations are done by the Commissioner of Railway Safety, independent of the Railway Ministry.
Suppression of Uncomfortable Findings: Independent reviews and reports exposing deeper faults are often buried or ignored. Eg: The Air Marshal J.K. Seth Committee Report (1997) identified serious aviation safety issues, but it was never implemented because it told inconvenient truths.
What systemic flaws affect India’s aviation safety framework?
Lack of Functional Independence in Investigations: The Aircraft Accident Investigation Bureau (AAIB) operates under the same ministry (MoCA) that regulates the aviation sector, compromising neutrality. Eg: After the Air India AI171 crash in June 2025, concerns were raised that the investigation might not be impartial due to overlapping roles of MoCA and AAIB.
Fragmented Oversight and Regulatory Capture: Aviation oversight in India suffers from poor coordination, limited resources, and influence by the very entities it is supposed to regulate. Eg: The J.K. Seth Committee Report (1997) pointed out such flaws, including regulatory capture, yet its recommendations remain largely unimplemented.
Reactive Rather Than Preventive Safety Culture: India’s aviation safety system often responds after accidents occur, rather than identifying and mitigating risks in advance.Eg: Multiple helicopter and flying school crashes in 2024–25 were not adequately investigated for systemic lapses, highlighting the absence of a proactive safety mechanism.
How does MoCA’s control lead to conflict of interest in aviation oversight?
MoCA Controls Both Regulation and Investigation: MoCA oversees the Directorate General of Civil Aviation (DGCA) and also controls the Aircraft Accident Investigation Bureau (AAIB), creating an inherent conflict between promoting aviation and investigating its failures. Eg: In the Air India AI171 crash (2025), MoCA was in charge of both regulating the airline and investigating the crash, raising doubts about impartiality.
Lack of Independent Appointments: Senior officials in both DGCA and AAIB are appointed by MoCA, making it difficult for these bodies to act independently or challenge government or airline lapses. Eg: The J.K. Seth Committee (1997) warned about lack of independence due to MoCA’s direct control over top appointments, yet no structural change followed.
Investigative Findings May Be Influenced or Suppressed: When the regulator and investigator are under the same authority, reports may be watered down or delayed to avoid political or bureaucratic accountability. Eg: The Kozhikode crash (2020) report’s recommendations were not fully implemented, with experts citing MoCA’s influence in diluting critical findings.
Why is pilot error often blamed in aviation accident reports?
Legally Convenient: Blaming the pilot simplifies legal liability and expedites insurance claims, avoiding lengthy investigations or broader accountability. Eg: In many crash reports, including Aurangabad crash (1993), pilot error was highlighted while structural or operational flaws were downplayed.
Shields Other Stakeholders: It protects airlines, maintenance agencies, air traffic control, and the regulator from scrutiny or punishment. Eg: In the Air India Express IX611 case (2018), suspected overloading was ignored while responsibility was pushed toward the flight crew.
Systemic Culture of Scapegoating: There’s a lack of a genuine no-blame culture in India’s aviation safety framework. Pilots, even posthumously, become convenient scapegoats. Eg: After the Kozhikode crash (2020), the pilot was quickly blamed, although systemic issues like runway design and poor weather protocols were also contributing factors.
Way forward:
Ensure Structural Independence of Investigative Bodies: Transfer the AAIB and DGCA out of the Ministry of Civil Aviation’s direct control and make them statutory authorities reporting to Parliament. This will eliminate conflict of interest and promote credible, impartial investigations.
Promote a No-Blame Safety Culture: Need to amend existing rules to prevent automatic criminal liability for pilots unless gross negligence is proven (e.g., Rule 19(3) of Aircraft Rules, 1937).
Mains PYQ:
[UPSC 2018] Describe various measures taken in India for Disaster Risk Reduction (DRR) before and after signing ‘Sendai Framework for DRR (2015-2030)’. How is this framework different from ‘Hyogo Framework for Action, 2005?
Linkage: The article explicitly frames an aircraft accident as a “wake-up call” and argues that India needs a system that “prevents failures, and not just manages the damage.” It states, “We cannot keep firefighting. We need a system that prevents failures”. This directly relates to the concept of Disaster Risk Reduction (DRR), which emphasises proactive measures and preparedness over reactive response.
The Union Finance Ministry has capped spending under the Mahatma Gandhi National Employment Guarantee Scheme (MGNREGS) at 60% of its total annual allocation for the first half of FY 2025-26.
About MGNREGS:
Legal Foundation: MGNREGS is a rights-based Centrally Sponsored Scheme launched under the MGNREGA Act of 2005 to ensure the Right to Work for rural households.
Origins:
The idea of employment guarantee in India began with Maharashtra’s pilot, Employment Guarantee Scheme (MEGS), in 1965 under the V. Naik government.
At the national level, the idea was first proposed in 1991 by then PM P. V. Narasimha Rao and later enacted in 2005.
Employment Guarantee: It provides 100 days of wage employment per year to any adult willing to do unskilled manual labour in rural India.
Legal Obligation: It is the first law in India that imposes a legal duty on the government to provide employment and compensate for non-compliance.
Development Goal: The scheme aims to promote livelihood security, inclusive growth, and rural development.
Key Features:
Statutory Right: Employment under MGNREGS is a legal entitlement, not just a welfare scheme.
Eligibility: Any rural adult aged 18 or above can apply and must be offered work within 15 days.
Proximity and Wages: Work must be provided within 5 km of the applicant’s residence with minimum wage, and delays attract compensation.
Unemployment Allowance: If work is not provided on time, the state must pay an allowance.
Demand-Driven Model: The scheme is worker-initiated, requiring the government to respond to demand.
Transparency and Audits: Regular social audits and online updates ensure accountability in job cards, muster rolls, and fund use.
Local Implementation: It is decentralised, led by Gram Panchayats, with support from block and state officials, and centrally funded.
Women’s Inclusion: At least one-third of beneficiaries must be women, enhancing gender equity.
Sustainable Assets: Projects focus on durable rural infrastructure like ponds, roads, canals, and plantations.
Rationale Behind the Spending Cap:
Expenditure Control: This cap is part of the Monthly/Quarterly Expenditure Plan to prevent front-loading of funds and mid-year shortages.
Previous Trends: In earlier years, over 70% of funds were spent by September, creating dues of ₹15,000–25,000 crore.
Current Status: As of June 2025, 28% of the budget is already used, while ₹19,200 crore in dues remain from FY25.
Criticism: Experts argue the cap undermines the demand-driven design of the act and may violate the legal right to work.
[UPSC 2006] Consider the following statements in respect of the National Rural Employment Guarantee Act, 2005:
1. The Act provides 100 days of employment to households as a fundamental right.
2. Women are given priority such that half of the employment seekers are women.
Options: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 *
Passively Managed Funds—those that track a market index without active stock selection—have become increasingly popular among investors seeking low-cost, predictable returns.
About Passively Managed Funds:
Passively managed funds, commonly known as passive funds, are investment vehicles designed to replicate the performance of a specific market index, such as the Nifty Fifty or the Sensex.
Unlike actively managed funds, the fund manager in a passive fund does not select stocks or make frequent buy-and-sell decisions.
Instead, the fund holds the same stocks in the same proportion as the underlying index.
How Passive Funds Work?
These funds track a benchmark index by investing in all or a representative sample of the securities in that index.
The objective is to mirror the index’s returns, not to outperform it.
As a result, they incur lower management costs and have minimal portfolio turnover.
Types of Passive Funds:
Index Funds:
These are mutual funds that can be purchased or redeemed directly from the fund house.
Transactions are processed only once a day, based on the day’s closing Net Asset Value.
They offer ease of use and are suitable for systematic investment plans and long-term investors.
Exchange Traded Funds:
These are funds listed on stock exchanges, like the National Stock Exchange or the Bombay Stock Exchange.
Investors buy or sell units during trading hours through brokers, just like stocks.
They require a dematerialised account and are suitable for investors seeking intraday trading flexibility.
Advantages of Passive Funds:
Low Expense Ratios: Because no active research or trading is involved.
Transparency: Holdings closely follow a well-known index.
Diversification: Spreads investment risk across multiple securities.
No Human Bias: Avoids mistakes due to the fund manager’s poor decisions.
Limitations:
No Outperformance: Returns will always be close to the index and cannot exceed it.
Tracking Error: Slight variation between the fund’s performance and the index due to operational reasons.
Limited Flexibility: Cannot adapt to sudden market downturns.
[UPSC 2025] Consider the following statements:
Statement I: As regards returns from an investment in a company, generally, bondholders are considered to be relatively at lower risk than stockholders.
Statement II: Bondholders are lenders to a company, whereas stockholders are its owners.
Statement III: For repayment purposes, bondholders are prioritised over stockholders by a company.
Which one of the following is correct in respect of the above statements?
(a) Both Statement II and Statement III are correct, and both of them explain Statement I *
(b) Both Statement I and Statement II are correct, and Statement I explains Statement II
(c) Only one of the Statements II and III is correct and that explains Statement I

Two recent maritime accidents off Kerala’s coast have spotlighted shipping safety, ecological risks, and the International Maritime Organisation’s (IMO) role in global maritime regulation.
About the International Maritime Organisation (IMO):
Overview: The IMO is a UN specialised agency that regulates international shipping and aims to prevent marine pollution from ships.
Establishment: It was established in 1948 via a UN conference in Geneva and formally came into existence in 1958. It is headquartered in London, United Kingdom.
Membership: It has 175 member states and 3 associate members. India joined in 1959.
Objective: To develop a fair and effective global regulatory framework for the shipping industry that is universally adopted and consistently implemented.
Legal Functions: It also addresses liability and compensation and facilitates international maritime traffic through legal frameworks.
World Maritime Day: It observes World Maritime Day on the last Thursday of September each year to promote awareness of maritime significance.
IMO Governance Structure:
Assembly: The highest governing body meets every 2 years.
Council: Comprises 40 members serving 2-year terms, acts as the executive organ, and focusing on safety and pollution control.
Committees: Five main committees and multiple subcommittees draft and adopt conventions, codes, and guidelines for maritime operations.
SOLAS (Safety of Life at Sea)Convention: Originating after the Titanic disaster, SOLAS mandates lifeboat capacity on both ship sides and is regularly updated by the IMO to meet modern safety standards.
India and IMO:
Overseeing Agency: IMO-related matters in India are handled by the Directorate General of Shipping.
Council Representation: India is a Category B member of the IMO Council, indicating its growing maritime influence.
Future Goals: Under Vision 2030 and Amrit Kaal Vision 2047, India plans to set up a dedicated IMO cell.
Conventions Not Yet Ratified: India has not yet ratified the 2004 Ballast Water Convention and the 2010 HNS Convention.
Flags of Convenience (FOC): Many ships operate under FOCs (e.g., Liberia, Marshall Islands) to bypass stringent regulations.
Who is Liable for Environmental Damage and Lost Cargo?
Owner Liability: Ship owners are liable for bothcargo loss and environmental damage under international law.
Bill of Lading: Cargo is transported under a bill of lading, a legal contract between ship owner and cargo holder.
Marine Insurance: P&I Clubs (Protection & Indemnity) cover liabilities related to cargo loss, environmental damage, and loss of life.
Liability Caps: While cargo liability is capped, environmental claims—especially for oil or toxic spills—can be uncapped and costly.
Polluter Pays Principle: The MARPOL Convention enforces that polluters bear the cost of environmental damage, even if national law limits compensation.
Wreck Liability: The Nairobi Convention (2007) holds ship owners responsible for wreck removal or financial liability within 200 nautical miles of a nation’s coast.
Recent Examples: Accidents like Wan Hai 503 and ELSA 3, involving toxic spills and lost containers, show the importance of robust legal frameworks.

Following the tragic crash of the Air India Boeing 787 Dreamliner in Ahmedabad, authorities concluded the identities of the victims using DNA analysis.
What is DNA?
Overview: DNA (Deoxyribonucleic Acid) is the molecule that carries genetic instructions essential for the development, growth, and reproduction of all living organisms.
Location in the Body: It is present in nearly every human cell and is unique to each person, except for identical twins.
Structure: DNA is made up of four chemical bases—Adenine (A), Cytosine (C), Guanine (G), and Thymine (T)—arranged in sequences that encode genetic data.
Biological Fingerprint: Due to its individual uniqueness, DNA acts like a biological fingerprint, useful in crime investigations and disaster victim identification.
How DNA Identification Works?
Use in Forensics: DNA is extracted from human remains when visual identification is not possible due to burns, decomposition, or trauma.
Reference Matching: Extracted DNA is compared with:
Family reference samples (from parents, children, siblings)
Personal belongings (like a toothbrush, razor, or hairbrush)
Sample Reliability: Bones and teeth are preferred in degraded conditions, as they preserve DNA more effectively.
Forensic Accuracy: Specialized forensic labs analyze and match DNA sequences, confirming identity with high levels of accuracy.
Common DNA Analysis Methods:
Short Tandem Repeat (STR) Analysis:
Focuses on short, repeating sequences of DNA that vary among individuals.
Requires nuclear DNA, typically from well-preserved samples.
Considered the gold standard for forensic identification.
Mitochondrial DNA (mtDNA) Analysis:
Extracts DNA from mitochondria, not the nucleus, making it more resilient in degraded samples.
Inherited only from the mother, allowing tracing through the maternal lineage.
Y-Chromosome Analysis:
Targets Y chromosomes, passed from father to son.
Useful for identifying male victims when paternal relatives are available.
Single Nucleotide Polymorphism (SNP) Analysis:
Detects single-letter changes in the DNA sequence.
Applied when DNA is highly degraded and other methods are less effective.
Can be used with reference items like personal hygiene tools.
[UPSC 2000] Assertion (A): DNA Finger-printing” has become a powerful tool to establish paternity and identity of criminals in rape and assault cases. Reason (R): Trace evidence such as hairs, saliva and dried semen are adequate for DNA analysis.
Options: (a) Both A and R are true, and R is the correct explanation of A (b) Both A and R are true, but R is not a correct explanation of A (c) A is true, but R is false (d) A is false, but R is true
The UPSC often picks real-life legal or social conflicts and then asks aspirants to explore the constitutional principles behind them. In 2014, for example, it asked whether films in India stand on a different footing under freedom of speech. This article builds on a similar theme—how freedom of expression collides with defamation in the digital age, through the ANI vs Wikipedia case.
Aspirants either stay stuck in textbook definitions or miss the real-world application of concepts like Article 19(1)(a), reasonable restrictions, or public interest. Many don’t know how to transition from theory to argument. For example, they might know “truth is a defence in defamation” but wouldn’t know how to use that in a Wikipedia-related controversy.
This article fills that gap. It takes a complex courtroom battle and unpacks it into clear, exam-relevant subthemes: ‘Should Digital Platforms Follow Editorial Standards?’, ‘Drawing the Line between Criticism and Defamation’, and ‘Important SC Judgments’. For instance, it shows how Wikipedia cited Indian Express and LiveLaw to defend its content—connecting it directly with the idea of “truth” and “public interest” in criticism. What makes this article stand out is that it doesn’t just explain the case—it teaches you how to think like a UPSC topper. It breaks down PYQ-style arguments, adds Supreme Court cases like Rajagopal v. State of Tamil Nadu, and builds a toolkit for writing high-quality GS 2 or Ethics answers. If you’re someone who struggles to move from facts to framing a balanced argument, this article is your shortcut.
This article explores the clash between freedom of expression and defamation in the digital age, using the ANI vs Wikipedia case as a lens. UPSC often asks questions that begin with real-life conflicts and lead into constitutional principles, like the 2014 Mains question on films and free speech.
Many aspirants know textbook terms like Article 19(1)(a) or “truth as a defence,” but struggle to apply them in real scenarios. This article bridges that gap. It breaks down key subtopics such as editorial standards for digital platforms, the line between criticism and defamation, and relevant Supreme Court cases. With clear examples and case references, it helps you move from theory to structured argument—exactly what UPSC expects.
PYQ ANCHORING
GS 2: What do you understand by the concept “freedom of speech and expression”? Does it cover hate speech also? Why do the films in India stand on a slightly different plane from other forms of expression? Discuss. [2014]
MICROTHEME: Fundamental Rights
What happens when a global encyclopedia clashes with a national news agency in the court of law? You get a legal drama playing out in real-time—on your screen and on Wikipedia.
It all started on July 9, 2024, when news agency ANI dragged the Wikimedia Foundation to the Delhi High Court. The trigger? A Wikipedia page that called ANI a “propaganda tool for the central government” and included content ANI claimed was defamatory. ANI hit back hard—asking for ₹2 crore in damages, a takedown of the content, a publishing ban on similar material, and even edit access to the page. But Wikipedia pushed back, defending its open, community-driven model and citing media sources like LiveLaw and Indian Express to back the content.The Delhi High Court ordered Wikipedia to reveal the identities of the editors behind the page—and even warned of a block if it didn’t comply. A new page popped up summarizing the legal battle itself, and ANI cried foul again, calling it contempt. The court agreed, ordering that page down. Now, the fight has reached the Supreme Court, where Wikimedia argues this threatens the fundamental right to document ongoing legal matters.
This case raises serious—and tricky—questions: Where do we draw the line between free speech and defamation in the digital age? Should courts force transparency on platforms built on anonymous contributions? And who really controls the narrative in the age of crowdsourced knowledge?
ANI vs Wikipedia Case
The dispute started on July 9, 2024, when news agency ANI filed a defamation case against the Wikimedia Foundation in the Delhi High Court. ANI claimed a Wikipedia page falsely labelled it a “propaganda tool for the central government” and contained defamatory content.
ANI sought: Takedown of the content, ₹2 crore in damages, a ban on publishing such material and access to edit the page (which was protected from ANI edits but open to others). Wikipedia defended its neutral, community-moderated platform, stating:
The page used content from credible media sources (e.g., LiveLaw, Indian Express)
The article was not authored by Wikipedia, but by independent contributors
The content is protected by free speech rights
In August 2024, Delhi HC ordered Wikipedia to disclose the identities of users who posted the edits; warned of a potential block. A new Wikipedia page summarizing the legal case itself was created. ANI filed a contempt plea, saying it interfered with ongoing proceedings.
Delhi HC ordered this new page to be taken down
Wikimedia challenged this in the Supreme Court, saying it threatens the right to free documentation of legal proceedings.
Supreme Court Proceedings (April 2025):
The Supreme Court has reserved its verdict on Wikimedia’s appeal against the Delhi High Court’s takedown order.
A decision is expected in the coming weeks.
This is a free speech vs defamation case.
ANI is upset about what was written about it on Wikipedia—especially being labelled as a mouthpiece of the government.
They sued Wikipedia and wanted the content removed, the page locked, and compensation.
The Delhi High Court took ANI’s side and ordered Wikipedia to:
Share user identities
Take down content that summarized the case
But Wikipedia pushed back, saying:
It’s just a publicly editable encyclopedia
The content was from real news reports
Court cases can be documented by the public
Now, the Supreme Court is looking into whether ANI’s hurt reputation justifies removing public documentation, and whether the High Court overstepped by ordering content takedown without proving contempt of court.
The case is important for freedom of expression, platform responsibility, and transparency in court reporting in India.
Should Digital Platforms Follow Editorial Standards Like News Media?
With the rise of digital platforms like Wikipedia, Reddit, and YouTube, the lines between traditional media and user-generated content have blurred. These platforms influence public opinion, shape narratives, and often serve as primary information sources. This raises a crucial question: should these platforms be held to the same editorial standards as legacy news media? While their structures differ, their societal impact increasingly demands scrutiny.
Point
Explanation
Example
1. Reach and Impact
Digital platforms influence public opinion just like newspapers and TV.
YouTube videos on political issues get millions of views, often more than news shows.
2. Risk of Misinformation
Lack of editorial checks allows fake or harmful content to spread.
Reddit threads spreading conspiracy theories with no fact-checking.
3. Trust and Credibility
Editorial rules improve the quality and trustworthiness of content.
Wikipedia’s rules on citing reliable sources improve its accuracy.
4. Model Differences
Platforms work differently from newsrooms but still need basic rules.
A podcast platform may not edit content but can still check for hate speech.
5. Inconsistent Moderation
Without standards, platforms often remove or keep content unfairly.
Instagram may remove political satire but allow offensive memes.
6. Protection from Pressure
Clear rules can protect platforms from political or corporate influence.
If standards exist, platforms can resist pressure to take down factual reports.
7. Safeguarding Democracy
People rely on these platforms for information, so they need responsibility.
During elections, misleading videos on Facebook can affect voter choices.
Defamation vs. Criticism: Drawing the Line in a Democracy
In a democracy, free speech and criticism are essential for holding power accountable. At the same time, individuals have the right to protect their reputation. The line between defamation and legitimate criticism lies in the intent, truth, and public interest behind a statement. The challenge is to protect both democratic discourse and personal dignity.
Distinguishing Defamation from Legitimate Criticism
Point
Explanation
Example
1. Truth as a Defense
Statements based on verified facts are protected.
The Punjab and Haryana High Court upheld journalists exposing the 2015 Vyapam scam based on evidence, protecting their right to report.
2. Public Interest Matters
Criticism made for public good is often considered fair comment.
The reporting on the Pegasus spyware scandal by media outlets, highlighting surveillance of activists and journalists, was seen as public interest.
3. Intent and Malice
Deliberate falsehoods meant to harm are defamation.
The defamation case against actor Kangana Ranaut for spreading false claims about certain individuals was cited as malicious intent.
4. Tone and Language
Constructive criticism is legitimate; abusive or hateful speech may be defamatory.
Politicians criticizing government policy on COVID-19 management is fair; hate speech against religious groups crosses into defamation.
5. Platform and Audience
Larger platforms have greater responsibility for accuracy.
The Delhi High Court’s order for Wikipedia to remove defamatory content about ANI showed how a widely accessed platform’s misinformation can have serious impact.
6. Private vs Public Figures
Public figures face more scrutiny but have protection from baseless attacks.
Coverage of former Prime Minister Modi’s policies is subject to criticism; however, baseless personal attacks against him have led to legal notices.
7. Legal Safeguards
Courts balance free speech and protection against defamation.
The Supreme Court’s ruling in Subramanian Swamy vs. Union of India upheld strong defamation laws but stressed they should not curb free speech unnecessarily.
The balance between free speech and reputation must be navigated carefully. While criticism is a democratic right, it should be fact-based and civil, not a tool for personal attacks.
Defamation Laws Around the World

New Zealand
Abolished criminal defamation in 1993; only civil claims remain.
USA
No federal criminal defamation law, but 24 states retain criminal defamation provisions.
Europe
About 75% of member states of the OSCE maintain criminal defamation laws despite international calls for decriminalization.
Important Supreme Court judgments on defamation
1. Subramanian Swamy v. Union of India (2016)
Key Point: Upheld the constitutionality of criminal defamation under Sections 499 and 500 of the IPC.
Court’s View: Right to reputation is part of the right to life under Article 21, and must be balanced against free speech under Article 19(1)(a).
Impact: Reinforced that defamation laws are a reasonable restriction on free speech.
2. Shreya Singhal v. Union of India (2015)
Key Point: While this case struck down Section 66A of the IT Act for violating free speech, it clarified that defamation remains a valid restriction under Article 19(2).
Impact: Helped distinguish between reasonable restrictions (like defamation) and vague, arbitrary laws on speech.
3. Rajagopal v. State of Tamil Nadu (1994) (a.k.a. Auto Shankar Case)
Key Point: Recognized the right to privacy and held that publishing without consent violates personal rights—unless content is part of the public record or public interest.
Impact: Set a precedent that public officials cannot sue for defamation just because information is inconvenient if it is true and based on public records.
4. Khushwant Singh v. Maneka Gandhi (2002)
Key Point: The court allowed the publication of certain controversial passages in Khushwant Singh’s autobiography, noting that public figures should be open to criticism.
Impact: Emphasized that public interest and fair comment are valid defences against defamation.
5. Bennett Coleman v. Union of India (1973)
Not about defamation directly, but crucial in establishing that freedom of the press is part of free speech.
Relevance: Forms the constitutional base when balancing defamation laws with press freedom.
Way Forward
Teach people how to spot fake news and unfair attacks. This helps everyone understand the difference between honest criticism and harmful lies.
Support fact-checking by trusted groups. When news and online content are checked carefully, people can trust what they read.
Make laws clearer about what counts as defamation. This stops people from using defamation laws to scare or silence those who speak up.
Encourage all media, including websites and social platforms, to follow good ethical rules. This means sharing honest and respectful criticism without spreading false or harmful info.
Create special courts that quickly handle defamation cases. This way, problems get solved fast and don’t drag on to intimidate critics.
Protect journalists and whistleblowers who expose corruption or wrongdoing. They should feel safe to speak up without fear of being sued unfairly.
Make digital platforms responsible for managing harmful content. They should work to stop defamation while still allowing people to share their opinions freely.
#BACK2BASICS: DEFAMATION
Defamation refers to the communication of a false statement that harms the reputation of an individual, business, product, group, government, religion, or nation.
Defamation Law in India// DOMINATE PRE
In India, defamation is recognised both as a criminal offence and a civil wrong, governed respectively under the Indian Penal Code (IPC) and the Code of Civil Procedure (CPC).
Civil Defamation: Under civil law, defamation is addressed through the Law of Torts, where the aggrieved party can claim damages as compensation for harm to their reputation.
Criminal Defamation: Defamation is a bailable, non-cognizable, and compoundable offence under criminal law. According to Section 500 of the IPC, the punishment may include simple imprisonment for up to two years, a fine, or both.
Constitutional Provisions
Article 19(1)(a):Guarantees the fundamental right to freedom of speech and expression.
Article 19(2):Allows for reasonable restrictions on this freedom in the interest of defamation, contempt of court, incitement to an offence, etc.
Legal Provisions on Defamation in India
Section 499 IPC: Defines defamation as making or publishing any statement (spoken, written, or by signs/visible representations) that harms reputation. The section extends defamation to statements about a “collection of persons” as well.
Exceptions under Section 499: Defamation is not applicable if the statement is:
True and made for the public good,
Related to the conduct of government officials,
Pertaining to any public question, or
Concerned with the merits of public performance.
Punishment (Section 500 IPC): Whoever commits defamation may be punished with imprisonment up to two years, a fine, or both.
How Does Criminal Defamation Work in India?
If someone feels that their reputation has been harmed by a false statement, they can choose to file a criminal defamation case. But unlike other serious crimes, criminal defamation has its own process.
The Legal Process: Step-by-Step
Not a Serious Crime (Legally Speaking): Criminal defamation is considered a non-cognisable and bailable offence, which means the police cannot arrest the accused just because someone filed a complaint. It also means no FIR is registered automatically.
Approach the Magistrate: Instead of going to the police, the aggrieved person usually files a private complaint before a magistrate. They must record their statement to convince the magistrate that the case is serious enough to proceed.
Summons and Bail: If the magistrate is satisfied, they issue summons to the accused. This is when the case officially begins, and the accused must apply for bail.
Is There a Case?: The magistrate checks if there is a prima facie (on the face of it) case. If yes, the trial moves forward. If not, the case is dismissed and the accused is let go without a full trial.
Why Is Criminal Defamation Controversial?
While protecting someone’s reputation is important, critics say using criminal law for this has serious drawbacks.
Concerns Raised:
Threat to Free Speech:The fear of going to jail can silence journalists, activists, and ordinary citizens from speaking the truth or expressing opinions.
Used to Harass:Some people use defamation cases to intimidate or harass critics, especially those exposing corruption or misconduct.
Disproportionate Punishment:Sending someone to prison for saying something offensive may seem like an overreaction when a civil suit could do the job.
Arguments in Favour of Decriminalising Defamation
Freedom to Speak Freely:Encourages open debate and expression without the threat of jail.
Proportionate Response:Civil penalties (like fines) are more appropriate than prison.
Lighter Load on Courts:Criminal cases clog up the judicial system. Civil suits are easier to manage.
Prevents Misuse:Stops powerful people from misusing defamation laws to suppress dissent.
Arguments Against Decriminalising Defamation
Protecting People’s Reputations:False statements can do serious damage—there should be accountability.
Fighting Fake News:Criminal laws act as a strong deterrent against false and malicious content.
Shielding the Vulnerable:People without power or access to lawyers may find criminal law a stronger safeguard.
Maintaining Social Harmony:Defamation laws help prevent public unrest by discouraging reckless statements.
What the Supreme Court Says
In the Subramanian Swamy v. Union of India case, the Supreme Court upheld the constitutionality of criminal defamation. The Court made some key points:
Balance is Key: Free speech is important, but so is a person’s right to their reputation.
Reasonable Restriction: Criminal defamation is a reasonable limit on speech, as allowed under Article 19(2) of the Constitution.
Dignity Matters: The Court ruled that the right to reputation is part of the right to life (Article 21) and must be protected alongside the right to free expression.
