Article 83 of Indian Constitution

Article 83 of the Constitution of India provides the duration of both the Houses of Parliament that is the Lok Sabha and the Rajya Sabha. It provides a five-year term to the Lok Sabha in order to ensure governance and the Rajya Sabha is a permanent body which does not have a fixed term. One-Third members of Rajya Sabha keep retiring every two years. In this article, we are going to discuss Article 83 of the constitution, its interpretations and significance. 

Article 83 of Indian Constitution Interpretation

Article 83 of the Indian Constitution states - “1)The Council of States shall not be subject to dissolution, but as nearly as possible one-third of the members thereof shall retire as soon as may be on the expiration of every second year in accordance with the provisions made in that behalf by Parliament by law. 2)The House of the People, unless sooner dissolved, shall continue for five years from the date appointed for its first meeting and no longer and the expiration of the said period of five years shall operate as a dissolution of the House: Provided that the said period may, while a Proclamation of Emergency is in operation, be extended by Parliament by law for a period not exceeding one year at a time and not extending in any case beyond a period of six months after the Proclamation has ceased to operate.

Article 83 of the Constitution of India can be interpreted in the following manner: 

  • According to Article 83, Rajya Sabha is a permanent body that has an indefinite tenure. 
  • One-third members of the Rajya Sabha retire every two years in order to maintain continuity and stability in the legislative process. 
  • The Lok Sabha on the other hand, has a defined tenure of five years and can also be dissolved earlier. 
  • The tenure of Lok Sabha can be extended in the case of national emergency. In such cases, the tenure can be extended up to six months after the Proclamations ceased to operate. 

Article 83 of the Constitution of India Significance

Article 83 talks about the tenure of the Houses of Parliament, with the goal of providing stability, continuity, and democratic accountability in the functioning of the Lok Sabha and Rajya Sabha. Article 83 is important because: 

  • The Rajya Sabha is declared as a permanent body not subject to dissolution, with one-third of its members retiring every two years, ensuring continuity in legislation.
  • The Lok Sabha has a fixed term of five years, unless dissolved earlier, which provides a definite electoral cycle, ensuring democratic renewal.

The article covers the legislative process at the state level, especially related to the President's assent to bills reserved by the Governor for consideration. This principle helps maintain a system of checks and balances for both the centre and the state and maintain a balanced federal structure of India. In this article, we are going to cover all about article 201, its interpretation, provisions and significance. 

Article 201 of Indian Constitution Background

To protect the national interests and ensure constitutional alignment, the framers of the Constitution of India gave power to the President of India to overlook some state bills using Article 201. This article is applicable to legislation that affects the judiciary and wider national implications. 

Article 201 of Constitution of India Interpretation

Article 201 provides the process under which a state legislature passes a bill that is reserved by the Governor for the President’s consideration. Under such cases, the President can: 

  • Give assent to the bill that becomes a law
  • Withhold assent to the bill and it does not become a law
  • Return the bill (Money bill cannot be returned)-  The President can return it with recommendations. The State Legislature must reconsider it within 6 months. If passed again (with or without changes), it is sent back for Presidential assent.

This provision ensures rigorous scrutiny of State laws that have broader constitutional or judicial consequences.

Article 201 Landmark Judgements 

Article 201 was considered for the following Legal Judgements: 

  • Hoechst Pharmaceuticals Ltd. v. State of Bihar (1983) 

 The Supreme Court held that the Presidential assent cures repugnancy—a State law conflicting with Central law becomes valid once the President assents.

  • Kohito Marak v. State of Meghalaya (2019)
    The Meghalaya High Court said that once a Bill is reserved for the President, his assent is very important for the Bill to become law.

Article 201 Importance

Article 201 has the following significance: 

  • Protect Federal Balance – Makes sure that State laws do not override national interest.
  • Keeps Judicial Independence Safe – Any law affecting High Court powers requires Presidential interference.
  • Promotes Uniformity – Helps bring consistency in laws across States on issues of national importance.

Takeaways From the Swachh Survekshan

Context

  • The ninth edition of Swachh Survekshan, hailed as the world’s largest cleanliness survey, marks a significant milestone in India’s urban sanitation landscape.
  • Spearheaded by the Swachh Bharat Mission (SBM)-Urban, this annual survey has evolved from a modest competition among fewer than 100 cities in 2016 to an extensive evaluation involving over 4,500 urban centres in 2024-25.
  • While public attention often fixates on rankings and awards, the deeper value of the survey lies in the critical insights it offers into urban waste management, city-level governance, and the evolving behavioural patterns of citizens and policymakers alike.

A Comprehensive Urban Sanitation Assessment

  • The survey serves as a crucial reality check for city managers and policymakers, offering an evidence-based assessment on ten comprehensive parameters, ranging from waste segregation, collection, and disposal to sanitation worker welfare and grievance redressal.
  • Its robust methodology, incorporating third-party verification and feedback from 140 million residents, lends credibility to its findings and amplifies its utility as a planning and monitoring tool.
  • In essence, Swachh Survekshan has transformed into a powerful lever for competition and performance enhancement, nudging cities across India toward cleaner futures.

 Significance and Key Features of the Survey

  • Encouraging Equitable Participation: Population Categories and the Super Swachh League
    • significant reform in this edition was the creation of the Super Swachh League, designed to break the monotony of a few cities repeatedly dominating the top ranks.
    • Indore, Surat, and Navi Mumbai, historically top performers, were placed in a new league, opening the door for cities like Ahmedabad, Bhopal, and Lucknow to rise in the rankings within their population categories.
    • The segmentation of cities into five population brackets, from those with fewer than 20,000 people to over one million, helped level the playing field and encouraged more diverse participation.
    • This democratisation has proved fruitful.
    • Odisha’s success exemplifies this shift: Bhubaneswar’s ascent from 34th to 9th place, and the rise of smaller cities like Aska and Chikiti, highlight how inclusive frameworks can foster widespread improvement.
  • A Growing Ecosystem of Best Practices and Innovation
    • Beyond rankings, the Swachh Survekshan serves as a repository of best practices that can be scaled and replicated.
    • The transformation of cities such as Indore and Surat reveals the possibilities of municipal innovation.
    • Indore's pioneering six-way waste segregation model, Surat’s monetisation of treated sewage, Pune’s ragpicker-run cooperatives, and Lucknow’s waste wonder park underscore how creativity, policy support, and community engagement can turn urban waste into an asset.
    • Similarly, Agra’s conversion of the toxic Kuberpur dumpsite into green space showcases the potential of modern remediation technologies like bioremediation and biomining.
  • Cleanliness as an Economic and Cultural Imperative
    • Tourist hubs and high-footfall areas received special attention in the latest survey, with Prayagraj being recognised for sanitation management during the Maha Kumbh.
    • As India accounts for a meagre 1.5% of global tourist arrivals, sustained cleanliness is essential not only for public health and aesthetics but also for enhancing the tourist experience and economic growth.
    • The thematic focus of Swachh Survekshan 2025, Reduce, Reuse, Recycle (RRR), underscores this broader ambition.
    • While the previous year's theme, waste to wealth, signalled an economic opportunity, India has yet to fully capitalise on the value embedded in its waste streams.

Challenges Ahead and The Way Forward

  • Despite visible progress, the survey reveals persistent challenges in developing behavioural change.
  • While SBM has successfully instilled societal rejection of open defecation, nurturing a similar mindset around waste minimisation, consumerism, and recycling has been elusive.
  • This behavioural inertia remains one of the most significant roadblocks to lasting impact.
  • Moreover, the daily generation of 1.5 lakh tonnes of solid waste poses a formidable challenge. Effective management will depend largely on the capacity and performance of ULBs.
  • Their ability to enforce waste segregation, ensure efficient collection, and handle plastic and e-waste will shape the next chapter in India’s urban cleanliness story.
  • Going forward, the focus must shift from celebrating momentary rankings to institutionalising cleanliness as a civic virtue and economic opportunity.
  • With policy support, community ownership, and technological innovation, Indian cities can transition from managing waste to creating wealth, dignity, and health for all.

Conclusion

  • India’s urban cleanliness journey, as illuminated by Swachh Survekshan 2024-25, is both inspiring and instructive.
  • It demonstrates that with the right mix of competition, data, public engagement, and political will, even the most chaotic waste systems can be reformed.
  • The remarkable turnaround of Surat from a garbage-laden city in the 1990s to a sanitation model today proves that change is not only possible, it is replicable.

The Reality of the Changing Dimensions of Warfare

Context

  • Niccolò Machiavelli’s view that politics is governed by power struggles and survival remains relevant today.
  • The traditional international order, shaped by events like the Peace of Westphalia and the Congress of Vienna, is crumbling.
  • As older norms fade, new tools of dominance, rooted in technological innovation, are rising.
  • The focus has shifted from diplomacy to digital warfare, reshaping both global politics and military strategy.

The Illusion of Post-War Peace

  • The end of World War II in 1945, followed by the atomic bombings of Hiroshima and Nagasaki, led many to believe in the arrival of a long-lasting peace enforced by American military might.
  • Concepts like a rules-based international order emerged. Yet, this peace proved to be an illusion.
  • From Korea to Vietnam and North Africa, conflicts persisted, revealing that global tensions had not subsided but transformed.
  • The Cold War’s end in 1989 did not usher in a peaceful era. Instead, new conflicts emerged, challenging earlier assumptions.
  • major turning point was Operation Desert Storm in 1991, which marked the start of modern high-tech warfare.
  • Precision-guided missiles, satellite intelligence, and three-dimensional strikes redefined battle doctrine.
  • This conflict began shifting war from manpower-heavy strategies to ones emphasising technology and speed.

9/11, the Era of Pretextual Warfare and The Rise of Digitised and Autonomous Warfare

  • 9/11 and The Era of Pretextual Warfare
    • September 11, 2001, was another defining moment. While some mark 1989 as the start of a new world order, others see 9/11 as the true catalyst.
    • The attacks allowed the U.S. and its allies to launch military interventions under the banner of combating terrorism.
    • However, this did not clarify whether the fundamentals of warfare were changing.
    • It took time to realise that the traditional rules of conflict were eroding. Military invasions began to rely more on perception and less on legality, and the justifications for war became increasingly ideological.
    • The seeds of algorithmic warfare had been planted, though their consequences were not yet visible.
  • The Rise of Digitised and Autonomous Warfare
    • Recent conflicts, particularly the Russia-Ukraine war since 2022 and the India-Pakistan clash in May 2025, have brought these changes into sharp focus.
    • Warfare today is driven by automation, AI, and network-centric strategies.
    • Drones, equipped with image recognition and loitering munitions, now play a central role in combat operations.
    • The 2025 India-Pakistan conflict showcased this shift. Both sides used fixed-wing drones, loitering munitions, and precision-guided bombs.
    • Fighter jets and missiles, like India’s BrahMos and Pakistan’s PL-15s, were deployed in tandem with advanced Turkish drones.
    • These engagements revealed a battlefield dominated by AI and autonomous systems, where speed, coordination, and digital integration matter more than physical presence.
    • The modern battlefield is now multi-domain, air, land, cyber, and space.
    • Cyberattacks, AI-driven targeting, and hypersonic weapons are shaping a new generation of warfare.
    • Traditional combat strategies, based on physical superiority, are fast becoming obsolete.

India’s Strategic Imperative

  • India must reassess its defence posture in this changing landscape.
  • Despite investments in platforms like the BrahMos and Rafale jets, the pace of indigenous technological development lags behind.
  • China, by contrast, has developed fifth-generation and is preparing sixth-generation fighter aircraft. It also leads in drone warfare and cyber capabilities.
  • India’s continued reliance on legacy systems and external procurements may limit its agility.
  • The May 2025 conflict underscores the need for rapid modernisation, particularly in autonomous systems, drones, AI, and cyber defence.
  • The advent of high-altitude, long-endurance UAVs has redefined surveillance and targeting, making them essential assets in any modern military engagement.
  • Furthermore, India must diversify its military hardware to be better prepared for a two-front conflict with Pakistan and China.

Conclusion

  • The evolution of conflict from conventional warfare to technologically driven, digital battlespaces signals the return of Machiavellian realism in new form, where power is defined not by land or numbers, but by information and innovation.
  • The post-WWII illusion of peace has been shattered, and the nature of war has fundamentally changed.
  • The future of warfare will be determined by those who master digital ecosystems, AI, and autonomous combat capabilities.

Critical Minerals and India’s Strategic Imperative - Building Resilience for the Future

Context:

  • Critical minerals are becoming the geoeconomic backbone of the 21st century, powering clean energy transitions, digital technologies, and national security systems.
  • For India, dependence on imports and limited domestic capacity threaten future industrial, technological, and strategic autonomy.

Critical Minerals - A New Geostrategic Axis:

  • Why critical minerals matter:
    • Critical minerals are metallic or non-metallic elements that are essential for clean energy systems, EVs, semiconductors, and strategic technologies, and whose supply chains are at risk of disruption.
    • Their demand is driven by energy transition, digitalisation, and supply chain resilience.
    • Examples include minerals of high importance like lithium, cobalt, nickel, graphite, and rare earth elements (REEs).
  • Geopolitical concerns:
    • High geographical concentration and opaque supply chains.
    • For example, China controls 90% of REE refining, 70% of cobalt processing, and 60% of lithium conversion.
    • China’s lead stems from decades of policy coherence and industrial planning.

India’s Critical Mineral Strategy:

  • National Policy initiatives:
    • 2022: Identification of 30 critical minerals by the Ministry of Mines.
    • 2025: Launch of National Critical Mineral Mission (NCMM) to secure supply chains.
  • Current challenges:
    • 100% import dependence on key minerals like lithium, cobalt, and REEs.
    • Domestic exploration is growing, for example, 195 exploration projects in the past year, and 227 approved for the upcoming year.

Auctions and Exploration - Progress and Bottlenecks:

  • Mines and Minerals (Development and Regulation) Act:
    • Inclusion of critical minerals enabled four rounds of auctions, fifth concluded in Jan 2025.
    • However, low bidder turnout due to high capital costs, inadequate processing capacity, and technical expertise gaps needs to be addressed.
  • Midstream vulnerability:
    • India lacks refining and processing capacity for battery-grade materials.
    • Continued foreign dependence, especially on China, looms large.

Building Industrial Capability - Proposed Solutions:

  • Establish mineral processing zones.
  • Offer Production-Linked Incentives (PLI) for refining, separation, and conversion industries.
  • Catalyse private investment in midstream processing.

Ensuring Mineral Security Amid Geopolitical Risks:

  • External disruptions: China’s export curbs on REEs impact India's automotive sector, including EV production.
  • Strategic recommendations:
    • Accelerate independent supply chain development.
    • Deepen bilateral partnerships, for example, ongoing collaboration with Australia, Argentina, shows a path forward.
    • Engage through Quad, G20, and Minerals Security Partnership (MSP).

Sustainability, Recycling, and ESG Compliance:

  • Circular economy approach:
    • Recycling of batteries and electronics to reduce import dependency.
    • Challenges: Informal recycling sector, lack of formal infrastructure, need for high-efficiency recovery systems, etc.
  • Sustainable mining and environmental, social and governance (ESG):
    • Many reserves are in tribal/ecologically sensitive zones.
    • Delays due to protests, legal hurdles, and ESG concerns.
    • Must adopt ESG frameworks, community participation, and local benefit-sharing models.

Way Forward - Policy and Strategic Alignment:

  • Conduct regular assessments of critical mineral demand and supply.
  • Update mineral lists as per evolving industrial and strategic priorities.
  • Develop critical mineral stockpiles to buffer against supply shocks.
  • Align mineral policy with foreign policy, energy policy, and industrial strategy.

Conclusion - India’s Strategic Imperative:

  • India must act decisively to reduce dependency, foster self-reliance, and build resilient and sustainable supply chains.
  • With the right policy execution, institutional backing, and international collaboration, India can emerge as a major global player in the critical mineral economy.

Foundation Day of Indian States and UTs, History, Significance

Default Image

After India gained independence in 1947, the country had 562 princely states. Most of these eventually accepted to become a part of the Indian Union. Over time, many of them were reorganised into new administrative states. A major shift occurred with the States Reorganization Act of 1956, which restructured Indian states based primarily on linguistic basis. Each state and union territory has its formation dates which is essential for every aspirant who is planning to appear in any competitive exam. The article shared below discusses the Foundation Day of Indian States and UTs.

Formation of Indian States and Union Territories

The Formation of Indian States and Union Territories began after independence in 1947. The country comprised over 565 princely states and 17 provinces, which were integrated into the Indian Union under the leadership of Sardar Vallabhbhai Patel and his secretary, V.P. Menon, by 1948. When the Constitution was being drafted in 1949, the First Schedule categorized the Indian territory into four parts:

  • Part A: Former Governor’s Provinces
  • Part B: Former Princely States or their groupings
  • Part C: Territories administered by Chief Commissioners appointed by the President
  • Part D: The Andaman and Nicobar Islands

States Reorganization Act of 1956

State Reorganization Act of 1956 was introduced to determine the boundaries of each princely state to safeguard the diversity of each linguistic identity especially after Andhra was carved out in 1953 for Telugu-speaking people. The States Reorganization Act reorganized the country into 14 states and 6 union territories, replacing the older classification under Parts A, B, C, and D of the Constitution.

Lumpy Skin Disease (LSD)

What is Lumpy Skin Disease (LSD)?

Lumby Skin Disease Latest News

With over 900 cattle infected with Lumpy Skin Disease (LSD) and more cases emerging daily, Pune district is staring at a potential decline in milk supply.

About Lumby Skin Disease

  • It is a highly infectious viral disease that affects all breeds of cattle and water buffalo. 
  • Causative Agent: It is caused by the lumpy skin disease virus (LSDV), a member of the genus Capripoxvirus (CaPV) within the family Poxviridae (smallpox and monkeypox viruses are also a part of the same family). 
  • LSDV is not zoonotic, so humans cannot get infected by the virus.
  • The disease is endemic in Africa and the Middle East and has been spreading increasingly in Europe and Southeast Asia over recent years.
  • The disease is most common in the wet summer and fall months, especially in low-lying areas near water bodies, but it can also occur in the dry season. 
  • LSD is a highly host-specific disease. It primarily affects cows and to a lesser extent, buffalo.
  • The disease is more severe in cattle compared to buffaloes in terms of morbidity and mortality. 
  • The disease is of economic importance as it can cause a temporary reduction in milk production, temporary or permanent sterility in bulls, damage to hides and, occasionally, death.

Lumby Skin Disease Transmission

  • It is transmitted by blood-feeding insects, such as certain species of flies, mosquitoes, or ticks.
  • Infected animals shed the virus through oral and nasal secretions, which may contaminate common feeding and water troughs.
  • Thus, the disease can either spread through direct contact with the vectors or through contaminated fodder and water.

Lumby Skin Disease Symptoms

  • The disease is characterized by high fever and enlarged superficial lymph nodes on the skin and peculiar multiple nodules or lumps on the skin. 
  • It can also lead to death, especially in animals that have not previously been exposed to the virus or have low immunity.

Lumby Skin Disease Treatment

  • There is no treatment for the virus, so prevention by vaccination is the most effective means of control.
  • The infected animals receive supportive care, which involves the use of antibiotics, painkillers, and wound care sprays to treat symptoms.

  • Location: It is a prominent water body situated within the vicinity of Gangaikonda Cholapuram in the Ariyalur District of Tamil Nadu, India.
  • It is locally known as Ponneri lake.

Historical Background

  • This historic lake owes its existence to Rajendra Chola I, a famous ruler of the Chola Dynasty 
  • It was dug by King Rajendra Chola I to celebrate his northern campaign, according to Tiruvalangadu Copper Plates.
  • To ensure a continuous water supply to Cholagangam Lake, a meticulously planned canal was constructed at a distance of sixty stones` throw from the Kollidam River.

Presidential Reference: Can the Supreme Court Clarify Past Rulings?

Presidential Reference

Presidential Reference Latest News

  • Recently, the Supreme Court issued notices to the Centre and all States on a Presidential Reference seeking its opinion on whether courts can compel the President and Governors to act within specified timelines on Bills passed by State legislatures. 
  • A Constitution Bench, led by Chief Justice B.R. Gavai, will begin detailed hearings by mid-August.

Background of the Case: SC’s April Verdict Under Scrutiny

  • The Reference was made under Article 143 of the Constitution after President Droupadi Murmu submitted 14 questions following the Court’s April 2025 judgment. 
  • That ruling, delivered in a case brought by the Tamil Nadu government, held that Governor R.N. Ravi’s delay in assenting to ten re-passed State Bills was illegal.
  • In this judgment, the apex court, for the first time, imposed judicially enforceable timelines on both Governors and the President.
  • The current Reference seeks clarity on whether courts can direct constitutional authorities on how and when to act. 

Scope and Significance of the Supreme Court’s Advisory Jurisdiction

  • Article 143(1) of the Indian Constitution allows the President to seek the Supreme Court’s opinion on legal or factual matters of significant public importance, even if no case is pending in court. 
  • This advisory power, inspired by the Government of India Act, 1935, has been used at least 14 times since Independence. 
  • The Court’s role in such cases is limited strictly to the questions raised in the Presidential Reference and cannot go beyond them. 
  • Although debated in the Constituent Assembly over concerns of political misuse, the provision was retained to help resolve constitutional deadlocks. 
  • To safeguard its use, Article 145(3) mandates that such References must be heard by a Constitution Bench of at least five judges.

Supreme Court’s Discretion to Decline Presidential References

  • While Article 143(1) empowers the President to seek the Supreme Court’s opinion, the Court is not bound to respond in every case. 
  • It holds discretionary authority to decline a Reference, as clarified in the Special Courts Bill case (1978), which interpreted the term “may” in Article 143 as conferring such discretion. 
  • However, if the Court chooses not to give an opinion, it must record its reasons. 
  • This was reaffirmed in Dr. M. Ismail Faruqui v. Union of India (1994), where the Court held that References involving expert evidence or political questions may be declined. 
  • Notably, in 1993, the Court refused to answer a Reference on the Ayodhya-Babri Masjid dispute due to the ongoing civil case and concerns of constitutional impropriety. 
  • Similarly, in 1982, the Court did not respond to a Reference on a proposed law related to resettlement of migrants in Jammu and Kashmir, as the law was enacted before the Court could intervene. 
  • These cases underscore the Court’s cautious approach in maintaining its judicial integrity and avoiding political entanglement.

Nature of Supreme Court’s Advisory Opinions

  • The binding nature of the Supreme Court’s advisory opinions remains debated
  • Article 141 makes only the “law declared” by the Court binding on all courts, and in St. Xavier’s College v. State of Gujarat (1974), the Court clarified that advisory opinions are not binding precedents but hold persuasive value
  • Still, some rulings, like R.K. Garg v. Union of India (1981), treated the reasoning in advisory opinions as binding, despite earlier caveats. 
  • The ambiguity continued in the Cauvery Water Disputes Tribunal case (1991), where the Court acknowledged advisory opinions as deserving “due weight and respect” but stopped short of declaring them binding. 
  • As of now, any opinion from the current Presidential Reference will not override the binding April 2025 ruling delivered under the Court’s adjudicatory powers. 
  • However, such an opinion will likely influence ongoing and future related cases, including those involving Kerala and Punjab.

Scope of Supreme Court’s Power to Modify April 2025 Verdict via Presidential Reference

  • The Supreme Court has clearly stated in past rulings, such as in the Cauvery Water Disputes Tribunal case, that Article 143 cannot be used by the executive to overturn or review a settled judicial decision
  • Once the Court has authoritatively ruled on a matter under its adjudicatory jurisdiction, there is no room for doubt that would justify a Presidential Reference. 
  • The only valid method to challenge such a decision is through review or curative petitions
  • However, the Court has also held, notably in the Natural Resources Allocation case (2012), that under Article 143(1), it may clarify or restate legal principles without disturbing the core decision or affecting parties’ rights
  • Similarly, in 1998, a Presidential Reference led to modifications in the collegium system without invalidating the original 1993 judgment
  • Hence, while the April 2025 ruling remains final and binding, the current Reference may be used to clarify or elaborate on its legal reasoning. 
  • With 14 questions raised—some going beyond the April ruling—the Constitution Bench may provide broader constitutional interpretations without undoing the earlier judgment.

Presidential Reference FAQs

Q1: What is a Presidential Reference?

Ans: It's a legal query the President sends to the Supreme Court under Article 143 on significant constitutional matters.

Q2: Can the Supreme Court reject a Reference?

Ans: Yes, it has discretionary power to decline and must record reasons, especially if the matter is political or pending.

Q3: Are advisory opinions binding?

Q4: Can the Court overturn its rulings via Reference?

Ans: No, but it can clarify or elaborate legal principles without disturbing prior binding decisions.

Q5: Why is the April 2025 ruling under scrutiny?

Ans: The government seeks clarity on whether courts can enforce timelines on the President and Governors for assenting Bills.

Paika Rebellion Controversy: Odisha’s Historic Uprising and the NCERT Debate

Paika Rebellion

Paika Rebellion Latest News

  • Former Odisha CM Naveen Patnaik has strongly objected to the exclusion of the 1817 Paika Rebellion from NCERT’s new Class VIII history textbook, terming it a “huge dishonour” to the valiant Paikas. 
  • The NCERT clarified that the rebellion would be included in the second volume of the textbook, to be released later this year.

The Paikas: Odisha’s Warrior Farmers

  • In 19th-century rural India, widespread discontent often erupted into armed resistance due to longstanding injustices and the disruptive policies of the expanding British East India Company. 
  • Among those who rose in rebellion were the Paikas of Odishaa class of traditional foot soldiers
  • Since the 16th century, Odisha’s Gajapati kings had recruited Paikas from various social groups to serve as military retainers. 
  • In return for their martial services, they were granted hereditary rent-free lands known as nish-kar jagirs, which they cultivated during times of peace. 
  • The erosion of their privileges under British rule sowed deep resentment, setting the stage for uprisings like the Paika Rebellion of 1817.

British Betrayal and the Fall of Khurda

  • In 1803, Colonel Harcourt’s British forces marched from Madras to Puri with little resistance and moved on to capture Cuttack. 
  • Harcourt struck a deal with Mukunda Deva II of Khurda, promising him compensation of ₹1 lakh and four parganas in exchange for safe passage through his territory.  However, the British failed to fully honour the agreement. 
  • In response, Jayee Rajguru, the king’s custodian, led 2,000 armed Paikas to Cuttack to pressure the British. 
  • While Harcourt paid ₹40,000, he withheld the promised parganas. Rajguru's subsequent conspiracy against British rule was thwarted, leading to his arrest and execution on December 6, 1806. 
  • The British then dethroned the king, destroyed Barunei Fort, seized royal lands, and exiled Mukunda Deva II to Puri.

Growing Resentment and the Road to Revolt

  • The fall of native rule in Odisha led to a sharp decline in the status and livelihood of the Paikas. 
  • Stripped of royal patronage and hereditary rent-free land, they were further burdened by the British East India Company’s new land revenue policies
  • These reforms forced many Odia landowners to sell their land cheaply to absentee Bengali landlords. 
  • Additionally, the switch to a rupee-based taxation system increased economic pressure, especially on tribals, who now had to meet rising demands from landlords paying taxes in silver. 
  • The British also tightened control over salt trade, extending it to coastal Odisha in 1814, further straining hill communities. 
  • These combined economic hardships and the loss of traditional privileges ultimately sparked a full-scale rebellion against British rule.

The Paika Rebellion of 1817

  • In March 1817, a group of around 400 Kondhs from Ghumusar, armed with traditional weapons, marched towards Khurda. 
  • They were soon joined by the Paikas, led by Bakshi Jagabandhu Bidyadhar, the former commander-in-chief of the Khurda kingdom and ex-holder of the Rodanga estate. 
  • Together, they launched a fierce revolt against British authority—attacking the Banpur police station, burning government buildings, looting the treasury, and killing officials. 
  • The uprising spread across several regions with bloody confrontations, but the British eventually suppressed the rebellion. 
  • Jagabandhu evaded capture for years, hiding in the forests, and finally surrendered in 1825 under negotiated terms.

Paika Rebellion and Contemporary Political Narratives in Odisha

  • The legacy of the Paika Rebellion has become a strong symbol of Odia pride and sub-nationalism.
  • In 2017, marking 200 years of the uprising, the then State government demanded that it be recognised as India’s “first war of independence,” citing its occurrence decades before the 1857 Revolt.
  • Although the Centre did not accept this status, the then Union Culture Minister stated in 2021 that the rebellion would be acknowledged in Class VIII textbooks as one of the early popular uprisings against British rule.
  • Prime Minister Modi honoured Paika descendants in 2017, and the then President Ram Nath Kovind laid the foundation of the Paika Memorial in 2019.

Paika Rebellion FAQs

Q1: Who were the Paikas?

Ans: Odisha’s warrior peasants who served the Gajapati kings and revolted when British rule ended their privileges.

Q2: Why did the Paika Rebellion happen?

Ans: British land reforms, salt monopoly, and loss of royal patronage triggered widespread unrest among Paikas and tribals.

Q3: What happened in the 1817 Rebellion?

Ans: Led by Bakshi Jagabandhu, Paikas and Kondhs attacked British posts but were eventually defeated.

Q4: Why is it politically sensitive?

Ans: Odisha leaders want it recognized as India’s first war of independence to assert cultural pride and historical identity.

Q5: What is NCERT’s stance?

Ans: NCERT clarified the rebellion will appear in the second textbook volume, set for release in September-October 2025.

Influence of Plastic Industry on Environmental Policies – A Growing Global Concern

Plastic Industry

Plastic Industry Latest News

  • The plastic industry has come under renewed scrutiny for allegedly deploying tactics to influence environmental policy in its favour, particularly during global treaty negotiations on plastic pollution.

Introduction

  • In recent years, environmental experts have grown increasingly concerned over the plastic industry’s influence on green policy-making. 
  • Reports and investigations indicate that the industry, backed by powerful fossil fuel interests, has employed tactics strikingly similar to those once used by the tobacco industry: sowing public doubt, delaying regulation, and manipulating narratives to shift responsibility from corporations to consumers.
  • These strategies are gaining prominence as governments globally attempt to tighten controls on plastic production and waste, particularly through the formulation of a potential UN treaty on plastic pollution.

Echoes of the Tobacco Industry Playbook

  • The plastic industry’s approach to avoiding regulatory pressure mirrors several historical tactics of the tobacco industry:
    • Shifting Responsibility to Consumers
      • While tobacco ads famously carried disclaimers like “Smoking is injurious to health”, even as they promoted smoking, the plastic industry blames consumers for not recycling effectively, thereby sidestepping the industry's responsibility in creating unsustainable plastic systems.
    • Funding Misleading Science and PR
      • Just as tobacco companies funded studies to deny smoking-related health risks, internal records from major plastic producers show they promoted plastic recycling from the 1980s onward despite privately acknowledging its technical and economic limitations. 
      • Public campaigns highlighting recyclability served to stall bans and stricter regulations.
    • Greenwashing and Mislabelling
      • Much like “light” cigarettes falsely marketed as healthier, today’s biodegradable and compostable plastics often fail to break down as claimed, especially in India’s underdeveloped waste management systems. 
      • Corporate greenwashing further distorts consumer understanding and weakens public demand for accountability.
      • One prominent example was Coca-Cola, which, despite promoting its sustainability image, quietly dropped its target of 25% reusable packaging by 2030 and backtracked on key recycling goals.

Targeting the Global South for Expansion

  • With regulatory pressure mounting in the Global North, the plastic industry has increasingly turned toward low- and middle-income nations to maintain market growth.
  • According to the OECD’s Global Plastic Outlook (2022):
    • Plastic consumption is expected to more than double in Sub-Saharan Africa by 2060.
    • In Asia, it could triple during the same period.
    • In contrast, growth is expected to be just 15% in Europe and 34% in North America.
  • Weaker environmental regulations, limited public awareness, and ineffective waste management infrastructure in these regions make them more vulnerable to plastic pollution and industry manipulation.

India’s Plastic Policy Landscape

  • India has taken several steps to curb plastic pollution, but faces implementation challenges.
    • Informal Sector: Backbone of India’s Plastic Recycling
      • An estimated 70% of India’s recycled plastic is collected and processed by the informal sector, ragpickers, sorters, and grassroots recyclers, who work in hazardous conditions with little legal protection or social security.
      • Recognising their contribution, the National Action for Mechanised Sanitation Ecosystem (NAMASTE) scheme launched in 2024 aims to:
        • Integrate waste workers into formal systems
        • Provide them with Ayushman Bharat health insurance, safety gear, and social security
      • As of May 2025:
        • Over 80,000 workers had been profiled
        • 45,700+ received personal protective equipment
        • 26,400+ were issued Ayushman Bharat cards
    • India’s Plastic Waste Management Rules (2016, amended 2022) mandate manufacturers to take financial and operational responsibility for the plastic they generate.
    • However, enforcement remains weak:
      • Only 11% of single-use plastic waste is covered by India’s current ban
      • Fewer than 50% of producers are reportedly complying with EPR guidelines
      • This undermines progress and allows the industry to continue unchecked in many areas.

Industry Lobbying in Global Negotiations

  • Recent rounds of the UN Intergovernmental Negotiating Committee (INC) for a global plastics treaty have been notably influenced by industry lobbying.
  • At INC-3, fossil fuel and chemical industry lobbyists outnumbered their previous participation by 36%
  • Civil society groups raised concerns about industry-backed delegates slowing down progress on binding commitments
  • Internal documents and reports from the Centre for Climate Integrity and Centre for International Environmental Law (CIEL) have exposed how the plastic industry has long known the inadequacy of recycling as a solution but continued to promote it to avoid scrutiny.
