Air Pollution

Study identifies sources of PM2.5 in northern India

Note4Students

From UPSC perspective, the following things are important :

Prelims level: PM 2.5

Why in the News?

A recent study published in Nature Communications has analyzed the sources and health impacts of PM2.5 pollution in Northern India, particularly in the Indo-Gangetic Plain.

About PM2.5

  • PM2.5 (Particulate Matter ≤2.5 microns) refers to tiny air pollutants small enough to penetrate deep into the lungs and enter the bloodstream.
  • These fine particles come from both natural sources (like dust storms and wildfires) and human activities (like burning fossil fuels and industrial emissions).
  • PM2.5 poses severe health risks, contributing to respiratory diseases, heart conditions, and reduced lung function.
  • The oxidative potential of PM2.5 is an important indicator of its toxicity and ability to cause cellular damage.

Key Findings of the Study

  1. Major Sources of PM2.5 in Northern India:
  • The study analyzed PM2.5 pollution across five locations in the Indo-Gangetic Plain, including Delhi and Kanpur.
  • Delhi: PM2.5 is mainly from vehicular emissions, fossil fuel burning, and residential heating.
  • Outside Delhi: It consists of ammonium sulfate, ammonium nitrate, and biomass-burning aerosols.
  1. PM2.5 Toxicity and Health Risks:
  • PM2.5 toxicity is linked to organic aerosols from inefficient combustion of biomass and fossil fuels.
  • Traffic emissions and residential fuel burning significantly contribute to PM2.5-related health risks.
  1. Traffic as a Major Contributor:
  • Hydrocarbon-like organic aerosols (HOA) from vehicular emissions were highest at urban roadside sites in Delhi (8 μg/m³).
  • HOA accounts for 50% of fossil fuel-derived aerosols, increasing to 40% in warmer months.
  1. Winter Pollution Due to Residential Heating and Cooking:
  • Cow dung combustion for heating and cooking in winter increases organic aerosols, with levels 10 times higher than in summer due to biomass burning and shallow boundary layers.
  1. India’s PM2.5 Toxicity Among the Highest Globally:
  • The study found that PM2.5 oxidative potential (toxicity) in Indian cities is up to 5 times higher than in Chinese and European cities.

Dramatic Performances Act, 1876

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Dramatic Performances Act, 1876

Why in the News?

PM Modi recently questioned why the colonial-era Dramatic Performances Act, 1876, which allowed authorities to ban plays deemed seditious, defamatory, or obscene, remained in force 75 years after independence.

What is the Dramatic Performances Act, 1876?

  • The Dramatic Performances Act, 1876, was a colonial-era law enacted by the British to suppress nationalist and anti-government sentiments in public performances.
  • The Act empowered the government to ban, regulate, or censor public plays, pantomimes, and dramas that were deemed:
    • Scandalous or defamatory
    • Seditious or inciting disaffection against the government
    • Obscene or corrupting to public morality
  • It also allowed magistrates to search, seize, and arrest performers and organizers without a warrant.
  • The law prescribed up to three months of imprisonment and/or a fine for violations.

References to Article 19 and Article 372

  • Conflict with Article 19(1)(a) – Right to Free Speech:
    • After independence, freedom of speech and expression was guaranteed under Article 19(1)(a).
    • The Allahabad High Court (1956) ruled the Act unconstitutional, stating it restricted free speech beyond reasonable limits.
  • Exceptions Under Article 19(2):
    • Article 19(2) allows reasonable restrictions on free speech for: Security of the state, public order, morality, and defamation.
    • The court ruled that the Dramatic Performances Act exceeded these limits.
  • Article 372 and Colonial Laws:
    • Article 372(1) of the Constitution states that laws in force before independence shall continue to be in effect unless repealed or modified by the Parliament.
    • Though invalidated in 1956, the law was formally repealed in 2018 under the Repealing and Amending (Second) Act, 2017.

PYQ:

[2014] What do you understand by the concept of “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.

Judicial Reforms

Article 136 of the Indian Constitution

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Article 136 of the Indian Constitution

Why in the News?

Vice President Jagdeep Dhankhar recently raised concerns over the wide usage of Special Leave Petitions (SLPs) under Article 136 of the Indian Constitution, stating that what was meant to be a “narrow slit” has now turned into a wide judicial intervention.

What is a Special Leave Petition (SLP) under Article 136?

  • A SLP is an extraordinary appeal mechanism that allows the Supreme Court (SC) to intervene in any judgment, decree, or order passed by a lower court or tribunal, except in matters related to the Armed Forces Tribunal.
  • SLP is discretionary, meaning the SC is NOT obligated to hear every petition filed under Article 136.
  • The concept of SLP originates from the Government of India Act, 1935, which gave a similar power to the Privy Council in colonial times.

Key Features of SLP:

  • Jurisdiction of Article 136:
    • The SC has the power to grant special leave to appeal against judgments of High Courts, tribunals, or other judicial bodies.
    • This allows the SC to examine cases that may not have a direct appeal provision under law.
  • Scope of Application:
    • SLPs can be filed in both civil and criminal cases.
    • It can be used even in cases where a High Court refuses to grant a certificate of appeal to the Supreme Court.
    • The SC may accept or reject an SLP without providing reasons.
  • Time Limit for Filing:
    • 90 days from the date of the High Court’s judgment.
    • 60 days if the High Court refuses to certify an appeal.
  • Judicial Discretion:
    • SLP is not an automatic right of appeal but is granted only in cases where the SC finds that a substantial question of law or injustice is involved.
    • Even if an SLP is accepted, the SC may later decline to interfere in the final decision.
  • Conversion into a Formal Appeal: If the SC grants leave under an SLP, the case turns into a full-fledged appeal, allowing both parties to present their arguments.

PYQ:

[2021] With reference to the Indian judiciary, consider the following statements:

  1. Any retired judge of the Supreme Court of India can be called back to sit and act as a Supreme Court judge by the Chief Justice of India with the prior permission of the President of India.
  2. A High Court in India has the power to review its own judgement as the Supreme Court does.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither I nor 2

[1st March 2025] The Hindu Op-ed: The steps that will shape India’s AI ambition

PYQ Relevance:

Q) The emergence of the Fourth Industrial Revolution (Digital Revolution) has initiated e-Governance as an integral part of government”. Discuss. (UPSC CSE 2020)

Mentor’s Comment: UPSC mains have always focused on the Fourth Industrial Revolution (Digital Revolution)  (2020) and the development of IT industries  (2021).

Despite a skilled workforce, Indian firms often lose AI deals due to capability gaps. In the intense AI race against Silicon Valley, China, and Southeast Asia, India must focus on fostering innovation and ensuring market regulations do not hinder its progress.

Today’s editorial talks about the AI-related challenges in India. This content would help in GS Paper 3 mains.

_

Let’s learn!

Why in the News?

In Bengaluru, Indian developers face tough competition from China for AI projects. To lead the AI race, India must focus on supportive regulations and enhancing technological capabilities.

What are the key issues related to Artificial Intelligence (AI) in India?

  • Job Displacement and Skill Gap: Increased AI adoption threatens to automate routine jobs, leading to large-scale unemployment and requiring a workforce with advanced digital skills. Example: The NASSCOM report (2023) highlighted that 69% of Indian tech workers need to upskill in AI and machine learning to remain employable as automation rises.
  • Algorithmic Bias and Ethical Concerns: AI systems can reflect and amplify societal biases, leading to discriminatory outcomes in hiring, lending, and public services. Example: In 2023, the Union Public Service Commission (UPSC) faced criticism when its AI-based screening system allegedly disadvantaged candidates from marginalized backgrounds during preliminary evaluations.
  • Misinformation and Deepfake Threats: AI-generated misinformation and deepfakes undermine public trust, pose security risks, and impact democratic processes. Example: During the 2024 Lok Sabha elections, deepfake videos impersonating political leaders circulated widely on social media, raising concerns about election manipulation.
  • Regulatory Uncertainty and Compliance Costs: The lack of a unified AI policy and fragmented regulations create legal ambiguity, increasing compliance burdens for Indian startups. Example: In 2023, Indian app developers filed a complaint with the Competition Commission of India (CCI) against Google for restrictive AI-related practices on the Play Store, citing unfair competition.
  • Global Competitiveness and Innovation Lag: Over-regulation and high compliance costs could hinder AI innovation, making India less competitive against global leaders like the U.S. and China. Example: India’s AI startup investments lag behind China and the U.S., with China attracting four times more AI funding in 2023, according to a Stanford AI Index report.

Where does India stand in the global Artificial Intelligence (AI) race?

  • Emerging AI Hub with Growing Investments: India is positioning itself as an emerging AI hub with increasing investments in AI research and development, but it still lags behind global leaders like the U.S. and China. Example: According to the Stanford AI Index Report 2023, India ranked fifth globally in AI research output but attracted significantly less AI funding compared to China and the U.S.
  • Government Initiatives to Boost AI Innovation: India has launched several initiatives to promote AI adoption, such as the “National Program on AI” and the establishment of AI research centers to enhance innovation and application. Example: In 2023, the Ministry of Electronics and Information Technology (MeitY) introduced the “IndiaAI” mission to promote AI-based solutions in healthcare, agriculture, and education.
  • Challenges in Global Competitiveness: Despite having a large talent pool, India faces challenges in scaling AI innovation due to fragmented regulations, limited high-performance computing resources, and competition from advanced economies. Example: While India produced over 20,000 AI and machine learning professionals in 2023, its AI exports remain limited compared to China’s dominance in AI-driven hardware and cloud solutions.

What is the current regulatory framework for Artificial Intelligence (AI)?

  • Existing Laws Governing AI Use: India does not have a dedicated AI law but regulates AI through existing legal frameworks like the Information Technology (IT) Act, 2000, which governs data protection, cybersecurity, and intermediary liability.
  • Sector-Specific Guidelines: Various government bodies have issued guidelines for AI applications in specific sectors. For example: RBI Guidelines for AI in financial services (e.g., credit scoring) and Telecom Regulatory Authority of India (TRAI) recommendations on AI in data privacy and telecommunications.
  • National Strategy on AI: The government launched the National Strategy for Artificial Intelligence (NITI Aayog, 2018) to guide AI research, ethical standards, and public-sector AI deployment. Example: Under the IndiaAI Mission (2023), the government aims to promote responsible AI use while fostering innovation across industries.
  • Competition and Data Protection Framework: The Competition Commission of India (CCI) monitors anti-competitive practices by tech firms using AI algorithms. The Digital Personal Data Protection Act, 2023 regulates how AI systems process personal data. Example: In 2023, the CCI investigated Google for alleged AI-related anti-competitive practices on the Play Store.
  • AI Ethics and Responsible Use: Guidelines on the ethical use of AI emphasize transparency, fairness, and accountability without imposing ex-ante (preemptive) regulation. Example: In 2023, the Ministry of Electronics and IT (MeitY) released advisory notes on preventing algorithmic bias and ensuring explainability in AI decisions.

Way forward: 

  • Comprehensive AI Policy Framework: Establish a unified and adaptive AI policy focusing on ethical guidelines, data privacy, and accountability to balance innovation with public interest.
  • Investment in AI Infrastructure and Skill Development: Enhance funding for AI research, expand high-performance computing resources, and implement large-scale reskilling programs to bridge the skill gap and improve global competitiveness.

The SEC and Hague Service Convention

Note4Students

From UPSC perspective, the following things are important :

Mains level: Hague Service Convention;

Why in the News?

On February 18, 2025, the U.S. Secuirty and Exchange commission asked the Indian government under the Hague Service Convention, to serve summons on Gautam Adani and Sagar Adani in a securities and wire fraud case.

What is the Hague Service Convention? 

  • The Hague Service Convention, formally known as the Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters (1965), is a multilateral treaty that facilitates the service of legal documents across international borders in civil and commercial cases.

How does it function? 

  • The Hague Service Convention standardizes the process for serving legal documents across borders in civil and commercial matters.
  • It operates through Central Authorities in member countries, ensuring efficient service, protecting defendants’ rights, and allowing alternative methods like postal service if permitted. It excludes criminal cases and non-signatory nations.

How is the U.S. Securities and Exchange Commission attempting to serve summons on the Adanis? 

  • Invoking the Hague Service Convention: The SEC has requested assistance from India’s Ministry of Law and Justice under Article 5(a) of the Hague Service Convention to officially deliver the summons to Gautam Adani and Sagar Adani.
  • Exploring Alternative Service Methods: The SEC is considering alternative methods under Rule 4(f) of the U.S. Federal Rules of Civil Procedure, which allows service through means like email or social media, if conventional methods face delays.
  • Proceeding Despite FCPA Suspension: Although the Trump administration has temporarily paused the Foreign Corrupt Practices Act (FCPA) enforcement for 180 days, the SEC argues that the pause does not apply retroactively, allowing their investigation into the Adanis to continue.

What are India’s reservations under the Convention? 

  • Opposition to Alternative Service Methods: India rejects all alternative service methods under Article 10 of the Convention, including postal service, diplomatic channels, and direct service by foreign judicial officers.
    • Example: A U.S. court cannot serve legal documents in India via U.S. consular channels unless the recipient is a U.S. national residing in India.
  • Mandatory Use of Central Authority: All service requests must go through India’s Ministry of Law and Justice, which is the designated central authority for processing foreign summons. Requests must be in English or include an English translation.
    • Example: In Punjab National Bank (International) Ltd. v. Boris Shipping Ltd. (2019), a U.K. court ruled that service through alternative methods was invalid due to India’s reservations.

How long does the service process typically take?

  • The service process under the Hague Service Convention in India typically takes six to eight months.
  • After receiving a request, India’s Ministry of Law and Justice verifies and forwards it to the appropriate authority.
  • Upon completion, an acknowledgement is issued to the requesting country, confirming successful service.

Way forward: 

  • Expedite Processing Mechanisms: Implement digital tracking and streamlined workflows within the Ministry of Law and Justice to reduce delays in handling service requests.
  • Strengthen Bilateral Cooperation: Enhance legal cooperation with key countries through bilateral agreements to complement the Hague Service Convention and facilitate faster document service.

Electoral Reforms In India

Counting matters: On delimitation, federalism, the Census

Note4Students

From UPSC perspective, the following things are important :

Mains level: Impact of delimitation exercise;

Why in the News?

Tamil Nadu Chief Minister M.K. Stalin has called for an all-party meeting on March 5 to discuss the delimitation exercise, aiming to start a national discussion on the issue.

What is the primary concern of Tamil Nadu regarding the delimitation exercise?

  • Loss of Parliamentary Representation: Tamil Nadu fears that if delimitation is based solely on population size, it may lose Lok Sabha seats due to its lower population growth compared to northern States. For instance, while Tamil Nadu’s electorate grew by 171% (1971-2024), undivided Bihar’s grew by 233%, which could lead to a reduction in Tamil Nadu’s political influence.
  • Penalty for Population Control Success: Tamil Nadu is concerned that its effective population control measures will be penalized. States with higher fertility rates (e.g., Uttar Pradesh, Bihar) might gain seats, while those with lower growth like Tamil Nadu and Kerala could lose out, despite their better health and development indicators.

What are the potential impacts of the delimitation exercise?

  • Shift in Political Power Dynamics: Delimitation could increase the number of representatives from northern States with higher populations (e.g., Uttar Pradesh and Bihar), thereby shifting political influence away from southern and western States that have implemented effective population control measures.
  • Federal Imbalance and Regional Inequality: Southern states that perform better in terms of health, education, and population control may feel penalized. For example, Kerala’s successful population policies could lead to fewer seats despite its contributions to national development, undermining the principle of cooperative federalism.
  • Resource Allocation Disparities: More seats for northern States could lead to greater influence over Union Budget allocations and central schemes, potentially reducing the share of resources to States with fewer representatives like Karnataka and Andhra Pradesh.
  • Political Tensions and Regional Discontent: Perceived favoritism towards northern States could increase regional tensions. For example, Tamil Nadu’s call for an all-party meeting reflects concerns that their voices will be marginalized, which may fuel political agitation and demands for policy reassessment.

Why was the delimitation exercise frozen based on the 1971 Census?

  • To Ensure Fairness Among States with Varying Population Growth: This aimed to protect the political representation of States that successfully implemented population control policies.
    • Example: Southern States like Tamil Nadu and Kerala have lower population growth but would lose seats if delimitation were updated, while Uttar Pradesh and Bihar would gain due to their higher population increases.
  • To Maintain the Balance of Power in Federal Governance: The freeze ensured that the distribution of parliamentary seats did not disrupt the federal structure by over-representing certain regions. This preserved a geographical balance in national decision-making.
    • Example: Despite Tamil Nadu’s slower population growth, its 39 Lok Sabha seats remain unchanged since 1971, allowing it to maintain a significant voice in national policies.

What steps has the Union government taken to clarify its position on maintaining proportional representation for Southern States?

  • Delimitation Freeze Extension: The government extended the freeze on parliamentary seat allocation based on population through the 42nd Amendment (1976) until 2001, and later extended it to 2026 through the 84th Amendment (2001).
  • Equitable Resource Allocation: The 15th Finance Commission (2021-26) used a balanced approach by including both population (2011 Census) and demographic performance to ensure fair distribution of resources, addressing concerns of Southern states.
    • Example: The Commission allocated 12.5% weightage for demographic performance, rewarding states with better population control.
  • Consultative Processes: The Union government engages with Southern states through inter-state council meetings and Finance Commission consultations to address their concerns about fair representation and resource distribution.
    • Example: In 2023, the government held deliberations on the implications of delimitation and reassured Southern states of equitable consideration in future seat revisions.

Way forward: 

  • Balanced Delimitation Framework: Implement a hybrid approach that considers both population size and demographic performance to ensure fair representation without penalizing states with successful population control policies.
  • Strengthen Federal Dialogue: Regular consultative mechanisms through Inter-State Councils and Finance Commissions to address regional concerns, ensuring equitable resource allocation and preserving the spirit of cooperative federalism.

With summers nearing, the arid and semi-arid regions of Rajasthan particularly in Churu, Jaisalmer, and Barmer districts largely rely on ‘Kundi’ system of traditional rainwater harvesting.

kundi

What is Kundi System?

  • Found in Churu, Rajasthan, kundis (or kunds) are traditional rainwater harvesting structures designed for storing drinking water.
  • A circular or rectangular pit, often lined with bricks or stones, is dug into the ground.
  • Rainwater is collected through sloped catchments and funneled into the kundi for storage.
  • A lid or stone slab covers the pit to prevent contamination and evaporation.
  • These structures help communities survive in regions with scarce groundwater and unpredictable rainfall.

Other Traditional Water Harvesting Systems in India

Khadin (Rajasthan) Earthen embankment (bund) built across slopes to retain surface runoff for moisture conservation and groundwater recharge, used since the 15th century.
Johads (Rajasthan, Haryana) Small crescent-shaped embankments that store rainwater, recharge groundwater, prevent runoff, and improve water availability.

New Species of Plants and Animals Discovered

Species in news: Doomsday Fish

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Doomsday Fish

Why in the News?

Recent sightings of the rare oarfish, also known as the “Doomsday Fish,” near the shores of Baja California Sur, Mexico, have sparked speculation and social media frenzy.

About the ‘Doomsday Fish’

  • Japanese Folklore calls the oarfish “Ryugu no tsukai” or “Sea God’s Palace Messenger” and believes its rare appearance signals an impending natural calamity.
  • The belief gained strength in 2011 when multiple oarfish washed ashore in Japan just before the Tohoku earthquake and tsunami (9.0 magnitude).
  • Some cultures also consider the oarfish a messenger of the deep, warning humans of major disturbances in the ocean.

Popular Legends

  • Some scientists suggest that deep-sea fishlike oarfish may be sensitive to underwater vibrations from fault lines and could surface before an earthquake.
    • However, no conclusive scientific evidence supports this theory.
  • Powerful ocean currents, storms, or underwater disturbances may push weakened or dying oarfish toward the surface.
  • The El Niño phenomenon or changes in water temperature might also affect their movements.
  • A 2019 study in the Bulletin of the Seismological Society of America found no relationship between oarfish sightings and earthquakes in Japan.

Electoral Reforms In India

[28th February 2025] The Hindu Op-ed: A process where free and fair elections will be a casualty

PYQ Relevance:

Q)To enhance the quality of democracy in India the Election Commission of India has proposed electoral reforms in 2016. What are the suggested reforms and how far are they significant to make democracy successful? (UPSC CSE 2017)

 

Mentor’s Comment: UPSC mains have always focused on the Election Commission of India (2017) and role of the Election Commission of India (2022).

The Chief Election Commissioner and Other Election Commissioners (Appointment, Conditions of Service and Term of Office) Bill, 2023, is the first law made under Article 324(5) of the Constitution for appointing the CEC and ECs. It was introduced after the Supreme Court’s March 2023 order, which aimed to ensure fair appointments through a high-power committee.

Today’s editorial discusses about the selection process of Election commissioners which is currently in news. This content would help in GS Paper2 mains.

_

Let’s learn!

Why in the News?

The Chief Election Commissioner and Other Election Commissioners (Appointment, Conditions of Service and Term of Office) Bill is flawed because it favors the candidate chosen by the government.

What are the key provisions of the 2023 Bill for appointing?

  • Selection Committee Composition: A three-member committee chaired by the Prime Minister, with the Leader of Opposition (LoP) in the Lok Sabha and a Cabinet Minister (nominated by the Prime Minister) as members.
  • Search Committee: Headed by the Law Minister, along with two senior bureaucrats, to prepare a list of five eligible candidates for consideration.
  • Appointment Procedure: The President of India appoints the Chief Election Commissioner (CEC) and Election Commissioners (ECs) based on the recommendations of the selection committee.
  • Seniority Principle: The senior-most Election Commissioner is to be appointed as the Chief Election Commissioner.
  • Binding Nature of Recommendations: It is mandatory for the President to appoint candidates recommended by the selection committee.

Why has the new law been challenged?

  • Deviation from Supreme Court’s Directive: In March 2023, a five-judge Bench of the Supreme Court, headed by Justice K.M. Joseph, directed that appointments should be made by a high-powered committee comprising the Prime Minister, LoP, and the Chief Justice of India (CJI). The new law replaces the CJI with a Cabinet Minister, weakening the independence of the selection process.
  • Lack of Transparency: The search committee’s list of eligible candidates is not made public, reducing accountability.
  • Government’s Dominance: The composition ensures a built-in majority for the government’s preferred candidate, undermining free and fair selection.

What constitutional infirmities have been identified in the selection process?

  • Government-Controlled Majority in the Selection Committee: The selection committee consists of the Prime Minister (Chairperson), a Cabinet Minister nominated by the Prime Minister, and the Leader of the Opposition (LoP).
    • This structure inherently creates a 2:1 majority in favor of the government, allowing the Prime Minister and the Cabinet Minister to dominate the decision-making process, undermining an independent and impartial selection.
  • Lack of Independent Oversight: Replacing the Chief Justice of India (CJI) with a Cabinet Minister weakens judicial oversight. This reduces checks and balances, as a Cabinet Minister is subordinate to the Prime Minister and unlikely to challenge the government’s preferences.
  • Violation of Fair and Objective Assessment: The process does not ensure objective evaluation of candidates due to the predetermined government majority. This may violate Article 14 (Right to Equality) as it denies a fair chance to qualified candidates outside the government’s favor and threatens the basic structure doctrine by compromising the independence of the Election Commission.

What are the key observations of the Supreme Court? 

  • Independence of the Election Commission is Vital: The Supreme Court emphasized that the Election Commission of India (ECI) must be independent and impartial to ensure free and fair elections, which is a fundamental feature of democracy.
    • Example: In the Election Commission of India vs. State of Tamil Nadu (1993), the Court held that the ECI has plenary powers to conduct free and fair elections, reinforcing the need for independent appointments.
  • Need for a Neutral Selection Process: The Court highlighted that appointments to constitutional bodies like the ECI should be made through a neutral and independent process to prevent executive dominance.
    • Example: In March 2023, the Constitution Bench directed that, until a law is enacted, the Prime Minister, LoP, and the CJI should select the CEC and ECs to ensure balanced decision-making.
  • Concerns over Executive Overreach: The Court warned that allowing the executive to control appointments could undermine the institution’s autonomy and jeopardize the integrity of the electoral process.
    • Example: The Court observed that the historical practice of Prime Minister-led appointments was unsatisfactory, as it compromised the Commission’s independence.
  • Violation of Article 14 (Right to Equality): The Court observed that a selection process favoring the government could violate Article 14 by denying an equal opportunity to eligible candidates.
    • Example: The current law creates a government-majority panel, allowing political bias in appointments and limiting fair competition.
  • Upholding the Basic Structure Doctrine: The Court reiterated that free and fair elections are part of the basic structure of the Constitution, which cannot be compromised by biased appointment procedures.
    • Example: In S.R. Bommai vs. Union of India (1994), the Court affirmed that any law threatening the democratic process would violate the basic structure doctrine and could be struck down.

Way forward: 

  • Restore Judicial Oversight: Reintroduce the Chief Justice of India (CJI) in the selection committee to ensure impartiality and independent oversight.
  • Enhance Transparency: Make the search committee’s candidate list public and adopt objective criteria for fair and unbiased selection.

Electoral Reforms In India

Counting matters: On delimitation, federalism, the Census

Note4Students

From UPSC perspective, the following things are important :

Mains level: Impact of delimitation exercise;

Why in the News?

Tamil Nadu Chief Minister M.K. Stalin has called for an all-party meeting on March 5 to discuss the delimitation exercise, aiming to start a national discussion on the issue.

What is the primary concern of Tamil Nadu regarding the delimitation exercise?

  • Loss of Parliamentary Representation: Tamil Nadu fears that if delimitation is based solely on population size, it may lose Lok Sabha seats due to its lower population growth compared to northern States. For instance, while Tamil Nadu’s electorate grew by 171% (1971-2024), undivided Bihar’s grew by 233%, which could lead to a reduction in Tamil Nadu’s political influence.
  • Penalty for Population Control Success: Tamil Nadu is concerned that its effective population control measures will be penalized. States with higher fertility rates (e.g., Uttar Pradesh, Bihar) might gain seats, while those with lower growth like Tamil Nadu and Kerala could lose out, despite their better health and development indicators.

What are the potential impacts of the delimitation exercise?

  • Shift in Political Power Dynamics: Delimitation could increase the number of representatives from northern States with higher populations (e.g., Uttar Pradesh and Bihar), thereby shifting political influence away from southern and western States that have implemented effective population control measures.
  • Federal Imbalance and Regional Inequality: Southern states that perform better in terms of health, education, and population control may feel penalized. For example, Kerala’s successful population policies could lead to fewer seats despite its contributions to national development, undermining the principle of cooperative federalism.
  • Resource Allocation Disparities: More seats for northern States could lead to greater influence over Union Budget allocations and central schemes, potentially reducing the share of resources to States with fewer representatives like Karnataka and Andhra Pradesh.
  • Political Tensions and Regional Discontent: Perceived favoritism towards northern States could increase regional tensions. For example, Tamil Nadu’s call for an all-party meeting reflects concerns that their voices will be marginalized, which may fuel political agitation and demands for policy reassessment.

Why was the delimitation exercise frozen based on the 1971 Census?

  • To Ensure Fairness Among States with Varying Population Growth: This aimed to protect the political representation of States that successfully implemented population control policies.
    • Example: Southern States like Tamil Nadu and Kerala have lower population growth but would lose seats if delimitation were updated, while Uttar Pradesh and Bihar would gain due to their higher population increases.
  • To Maintain the Balance of Power in Federal Governance: The freeze ensured that the distribution of parliamentary seats did not disrupt the federal structure by over-representing certain regions. This preserved a geographical balance in national decision-making.
    • Example: Despite Tamil Nadu’s slower population growth, its 39 Lok Sabha seats remain unchanged since 1971, allowing it to maintain a significant voice in national policies.

What steps has the Union government taken to clarify its position on maintaining proportional representation for Southern States?

  • Delimitation Freeze Extension: The government extended the freeze on parliamentary seat allocation based on population through the 42nd Amendment (1976) until 2001, and later extended it to 2026 through the 84th Amendment (2001).
  • Equitable Resource Allocation: The 15th Finance Commission (2021-26) used a balanced approach by including both population (2011 Census) and demographic performance to ensure fair distribution of resources, addressing concerns of Southern states.
    • Example: The Commission allocated 12.5% weightage for demographic performance, rewarding states with better population control.
  • Consultative Processes: The Union government engages with Southern states through inter-state council meetings and Finance Commission consultations to address their concerns about fair representation and resource distribution.
    • Example: In 2023, the government held deliberations on the implications of delimitation and reassured Southern states of equitable consideration in future seat revisions.

Way forward: 

  • Balanced Delimitation Framework: Implement a hybrid approach that considers both population size and demographic performance to ensure fair representation without penalizing states with successful population control policies.
  • Strengthen Federal Dialogue: Regular consultative mechanisms through Inter-State Councils and Finance Commissions to address regional concerns, ensuring equitable resource allocation and preserving the spirit of cooperative federalism.

Capital Markets: Challenges and Developments

The SEC and Hague Service Convention

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Hague Service Convention;

Why in the News?

On February 18, 2025, the U.S. Secuirty and Exchange commission asked the Indian government under the Hague Service Convention, to serve summons on Gautam Adani and Sagar Adani in a securities and wire fraud case.

What is the Hague Service Convention? 

  • The Hague Service Convention, formally known as the Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters (1965), is a multilateral treaty that facilitates the service of legal documents across international borders in civil and commercial cases.

How does it work? 

  • The Hague Service Convention standardizes the process for serving legal documents across borders in civil and commercial matters. It operates through Central Authorities in member countries, ensuring efficient service, protecting defendants’ rights, and allowing alternative methods like postal service if permitted. It excludes criminal cases and non-signatory nations.

How is the U.S. Securities and Exchange Commission attempting to serve summons on the Adanis? 

  • Invoking the Hague Service Convention: The SEC has requested assistance from India’s Ministry of Law and Justice under Article 5(a) of the Hague Service Convention to officially deliver the summons to Gautam Adani and Sagar Adani.
  • Exploring Alternative Service Methods: The SEC is considering alternative methods under Rule 4(f) of the U.S. Federal Rules of Civil Procedure, which allows service through means like email or social media, if conventional methods face delays.
  • Proceeding Despite FCPA Suspension: Although the Trump administration has temporarily paused the Foreign Corrupt Practices Act (FCPA) enforcement for 180 days, the SEC argues that the pause does not apply retroactively, allowing their investigation into the Adanis to continue.

What are India’s reservations under the Convention? 

  • Opposition to Alternative Service Methods: India rejects all alternative service methods under Article 10 of the Convention, including postal service, diplomatic channels, and direct service by foreign judicial officers.
    • Example: A U.S. court cannot serve legal documents in India via U.S. consular channels unless the recipient is a U.S. national residing in India.
  • Mandatory Use of Central Authority: All service requests must go through India’s Ministry of Law and Justice, which is the designated central authority for processing foreign summons. Requests must be in English or include an English translation.
    • Example: In Punjab National Bank (International) Ltd. v. Boris Shipping Ltd. (2019), a U.K. court ruled that service through alternative methods was invalid due to India’s reservations.

How long does the service process typically take?

  • The service process under the Hague Service Convention in India typically takes six to eight months. After receiving a request, India’s Ministry of Law and Justice verifies and forwards it to the appropriate authority. Upon completion, an acknowledgement is issued to the requesting country, confirming successful service.

Way forward: 

  • Expedite Processing Mechanisms: Implement digital tracking and streamlined workflows within the Ministry of Law and Justice to reduce delays in handling service requests.
  • Strengthen Bilateral Cooperation: Enhance legal cooperation with key countries through bilateral agreements to complement the Hague Service Convention and facilitate faster document service.

Air Pollution

[27th February 2025] The Hindu Op-ed: Coal power is costing India up to 10% of its rice and wheat crops

PYQ Relevance:

Q) “In spite of adverse environmental impact, coal mining is still inevitable for Development”. Discuss. (UPSC CSE 2017)

 

Mentor’s Comment: UPSC mains have always focused on the diverse environmental impact of coal  (2017), and environmental impacts of coal-fired thermal plants(2014).

India relies on coal for 65% of its electricity due to its low cost and large reserves. Coal-fired power plants release harmful gases like CO₂, SOx, NOx, and particulate matter, causing pollution and climate issues. Using Low NOx Burners with Over Fire Air technology can reduce NOx emissions by 45-80% without affecting power generation.

Today’s editorial discusses pollution caused by coal-fired power plants in India. This information is relevant for GS Paper 3 in the UPSC Mains exam.

_

Let’s learn!

Why in the News?

New research from Stanford University in the US shows that coal-fired power plants are reducing India’s rice and wheat production, causing up to a 10% loss in several states.

Why did the researchers focus on nitrogen dioxide (NO₂) emissions? 

  • Phytotoxic Effects on Crops: NO₂ is phytotoxic, meaning it directly harms plant health by interfering with cellular functions and enzymatic activities. Example: In agricultural areas near coal plants, NO₂ exposure leads to lower chlorophyll levels, reducing plant vitality and yield.
  • Formation of Secondary Pollutants: NO₂ contributes to the formation of ground-level ozone, which further damages crops by limiting photosynthesis and causing oxidative stress. Example: Increased ozone formation near coal hubs like Chhattisgarh exacerbates crop loss during peak growing seasons.
  • Limited Existing Research in India: While global studies link NO₂ to agricultural damage, there was no systematic study at the power-plant level in India. Example: This research fills the gap by connecting NO₂ emissions from coal plants directly to wheat and rice yield losses.
  • Satellite Data Availability: Advanced satellites like TROPOMI allow precise tracking of NO₂ concentrations, making it easier to study the pollutant’s widespread effects. Example: Researchers used satellite-derived vegetation indices (NIRv) to measure crop health across polluted regions.
  • High Contribution from Coal Plants: Coal-fired power plants are a major source of NO₂ emissions, especially in industrial and agricultural belts. Example: In Chhattisgarh, around 19% of monsoon-season NO₂ comes from coal plants, causing significant crop damage.

How does this pollutant impact plant health and crop yield?

  • Disruption of Photosynthesis: NO₂ reduces the amount of sunlight available for photosynthesis by forming secondary pollutants like particulate matter. This limits energy production in plants. Example: In areas near coal plants, reduced sunlight exposure leads to a 5-10% decline in rice and wheat yields in states like West Bengal and Madhya Pradesh.
  • Cellular and Enzymatic Damage: NO₂ interferes with crucial cellular processes and enzymatic functions, weakening plant growth and reducing their ability to absorb nutrients. Example: Crops exposed to high NO₂ levels in Chhattisgarh show slower growth and lower productivity, especially during peak seasons.
  • Ozone Formation and Oxidative Stress: NO₂ contributes to ground-level ozone, which causes oxidative stress in plants, leading to leaf damage and reduced crop yields. Example: In Uttar Pradesh, where overall NO₂ levels are high, wheat crops suffer significant losses due to ozone-induced stress during the winter season.

Which states show the highest agricultural losses?

  • Chhattisgarh: The most affected region with the highest share of NO₂ pollution from coal plants (19% during the monsoon and 12.5% in winter). It is a major hub for coal-fired power generation, leading to severe air pollution and crop yield losses.
  • West Bengal: There are significant NO₂ exposure from coal plants that affects 5.7% of cropland, with yield losses between 5-10% and even greater than 10% in some areas. The proximity of coal plants to fertile agricultural zones increases the impact on rice and wheat production.
  • Madhya Pradesh: About 5.9% of cropland near coal plants experiences 5-10% yield losses, while 11.9% of agricultural land could face losses exceeding 10%.
  • Uttar Pradesh: High overall NO₂ pollution, but only a small portion originates from coal-fired power plants. The other industrial sources dominate NO₂ emissions, yet coal plants still add to the burden on winter wheat yields.
  • Tamil Nadu: Low overall NO₂ levels but a large share comes from coal plants, disproportionately affecting local agriculture. The concentration of coal-fired power plants contributes a substantial portion of the region’s air pollution.

What steps have been taken by the Indian government? 

  • Increased Budget Allocation for Coal Sector: The 2025-2026 Union Budget has increased the allocation for the Ministry of Coal by 255% over the revised estimates of FY 2024-2025, reflecting a focus on managing coal resources and addressing environmental concerns.
  • Pollution Control Mandates: The government has introduced emission norms for coal-fired power plants, requiring the installation of pollution control equipment like Flue Gas Desulphurization (FGD) to reduce nitrogen oxides (NO₂) and other pollutants.
  • Renewable Energy Promotion: Policies such as the National Solar Mission and incentives for renewable energy aim to reduce coal dependency and minimize air pollution while promoting cleaner energy alternatives.

Way forward: 

  • Strengthen Emission Regulations: Implement stricter NO₂ emission limits for coal-fired power plants, enforce regular monitoring, and expedite the adoption of advanced pollution control technologies like selective catalytic reduction (SCR).
  • Promote Sustainable Agriculture and Clean Energy: Support farmers in NO₂-affected regions with resilient crop varieties and promote a transition to renewable energy through increased investment in solar and wind infrastructure.
