  • On the allegations against the SEBI chief      

    Why in the News?

    Hindenburg Research has alleged SEBI Chairperson Madhabi Puri Buch and her husband held stakes in Adani-linked offshore funds, implying bias in SEBI’s Adani investigation.

    Accusations Against SEBI Chairman Madhabi Puri Buch 

    • Hindenburg Research has accused SEBI Chairman Madhabi Puri Buch of conflicts of interest related to offshore funds tied to the Adani Group, financial opacity regarding a consulting firm transferred to her husband, and potential favoritism towards Blackstone, where her husband is a senior advisor. 

    Status of the Ongoing Investigation by SEBI

    • Supreme Court Oversight: The Supreme Court has directed SEBI to investigate the allegations made by Hindenburg Research.
    • Show Cause Notice by SEBI: In June 2024, SEBI issued a show cause notice to Hindenburg Research, indicating that the regulator is actively pursuing the matter.

    About SEBI’s Code on Conflict of Interest:

    According to SEBI’s Code on Conflict of Interest, board members, including the Chairperson, are prohibited from holding any other office of profit or engaging in professional activities that involve receiving a salary or professional fees.It can constitute a number of different things that need to be disclosed by the concerned board member:

    • Certain transactions in shares: The Code says that a member must disclose their, and their family’s (spouse, dependent children below 18 years of age) holdings within 15 days of the assumption of Office, and annually update this disclosure.
    • Outside private activities: SEBI board members are not allowed to hold any other ‘office of profit’.
    • Acceptance of gifts: Board members are not allowed to accept “any gift (whose value exceeds Rs 1,000) by whatever name called, to the extent possible, from a regulated entity”. If they do, they have to hand it over to the General Services Department of the SEBI.
    • Miscellaneous: Members are bound to disclose “any post, other employment or fiduciary position” which they hold or have held in the past five years, in connection with any regulated entity.

    Way forward: 

    • Enhance stricter disclosure requirements:  SEBI should implement stricter disclosure requirements for all board members, including the Chairperson, ensuring transparency about their financial interests, past affiliations, and potential conflicts.
    • Establishing an Independent Ethics Committee: An independent ethics committee should be created to oversee and review any potential conflicts of interest involving SEBI board members.

    Mains: Issues related to Section 70 of the PMLA;

    Mentor comments: Two recent Supreme Court observations in the bail petitions of Delhi CM Arvind Kejriwal and ex-Deputy CM Manish Sisodia highlight significant legal issues. Justice Sanjiv Khanna’s Bench questioned the role of the Aam Aadmi Party (AAP) in a PMLA case involving its leaders, asking if the party itself could be made an accused. This led the Enforcement Directorate to include AAP as an accused in Mr. Kejriwal’s case, marking the first time a political party is implicated under PMLA. This raises serious concerns given the pivotal role of parties in a parliamentary democracy.

    Let’s learn! 

    Why in the News?

    Two Supreme Court Benches questioned the role of political parties under the PMLA, leading to AAP being accused, which raises important constitutional issues.

    About PMLA: 

    The Prevention of Money Laundering Act, 2002 (PMLA) is a significant piece of legislation in India aimed at combating money laundering and related financial crimes. 

    Objectives:
    1. The PMLA is designed to prevent the process of money laundering, which involves concealing the origins of illegally obtained money.
    2. The Act provides for the confiscation of properties derived from or involved in money laundering activities.It establishes mechanisms for the detection and investigation of money laundering offenses.

    Issues related to Section 70 of the PMLA:

    • Application of Section 70 of PMLA to Political Parties: The legal question arises whether political parties can be categorized under the definition of “company” or “association of individuals” as per Section 70 of the PMLA. The law typically applies to bodies corporate or firms, which are transactional entities, unlike political parties.
    • Distinction in Definitions: Section 29A of the Representation of the People Act (RPA), 1951, defines a political party as an association of citizens that calls itself a political party. This specific designation creates a legal distinction between general associations of individuals and political parties, it means political parties may not be intended to fall under the scope of Section 70 of the PMLA.
    • Ejusdem Generis Interpretation: The legal principle of ejusdem generis suggests that “association of individuals” under Section 70 should be interpreted as entities similar to bodies corporate or firms. Since political parties are not engaged in business or transactional activities like these entities, their inclusion under Section 70 is legally questionable.

    Issues related to Policy and criminality

    • Cabinet Decision-Making and Accountability: The cabinet, as the highest decision-making body in a parliamentary democracy, is collectively responsible for policy decisions. The judiciary typically does not examine the motives or correctness of cabinet policies, focusing instead on the process and legality. Charging individual ministers with criminality for collective cabinet decisions undermines the collective principle.
    • Ivor Jennings’ View on Cabinet Role: Constitutional authority Ivor Jennings describes the cabinet as the “directing body of national policy,” emphasizing that it is accountable to the legislature and ultimately to the people, who can disapprove of policies through democratic processes.
    • Policy vs. Criminality in Judicial Interpretation: The observation by the Bench in Mr. Sisodia’s case highlights the difficulty in drawing a line between policy decisions and criminal actions. Criminal charges against individual ministers for decisions made by the cabinet may disrupt the functioning of the cabinet and are legally unsustainable in a parliamentary democracy.

    Way forward: 

    • Clarification through Legislative Amendment: To address the ambiguity surrounding the applicability of Section 70 of the PMLA to political parties, the legislature could consider amending the PMLA to explicitly clarify whether political parties fall under the definition of “association of individuals.” This would provide legal certainty and prevent potential misuse or misinterpretation of the law.
    • Judicial Guidelines on Policy and Criminality: The judiciary could establish clear guidelines on the distinction between policy decisions made by the cabinet and criminal actions taken by individual ministers. These guidelines would help ensure that the cabinet’s collective responsibility is preserved while allowing for accountability in cases of individual misconduct that fall outside the scope of legitimate policy-making.
  • What is the Google ‘monopoly’ antitrust case and how does it affect consumers?     

    Why in the news?

    US Federal court ruled Google’s $26 billion payments to default on smartphone browsers violated US antitrust law, blocking competitors and benefiting the Justice Department.

    About Google’s Antitrust Case

    • The U.S. Department of Justice (DOJ) brought an antitrust case against Google, accusing it of maintaining a monopoly in the online search and advertising sectors.
    • The DOJ argued that Google’s dominance was achieved through exclusive distribution agreements, which prevented competitors from succeeding in the market.

    What Did the Ruling State?

    • Google Monopolistic Practices: Google broke antitrust laws to keep its monopoly on “general search services” and “general search text ads.”
    • Note: The Sherman Antitrust Act is a landmark U.S. federal law enacted in 1890 to promote competition and prevent monopolistic practices.
    • Advantageous position due to the “default” search engine: The Google company has an unseen advantage over its competitors where it’s search engine processes an estimated 8.5 billion queries per day worldwide.
      • The present judgment by US District of Colombia limits itself to the relevant geographic market of the US.
    • Paying billions to smartphone makers: Google was accused of paying billions to smartphone makers like Apple and Samsung to ensure Google was the default search engine on their devices and browsers.

    How Do Monopolistic Practices Harm Consumer Experience?

    • Impact on Competition: Monopolistic practices, like those exhibited by Google, stifle competition by preventing rivals from entering the market and can lead to higher prices and reduced innovation.
    • Unfair Platform for Start-ups: The new start-ups would have to surmount the entry barriers to create a GSE of comparable quality to Google. These barriers would cost high capital, access to distribution channels, and brand recognition.
    • Quality Degradation: A monopolist may lose the incentive to improve the quality of its products, as there is little risk of losing customers to competitors.
      • The ruling highlighted that Google conducted a study in 2020 that showed it would not lose search revenue even if it significantly reduced the quality of its search product.
    • Limites the choices of consumer: When a company holds a monopoly, consumers are often left with few alternatives, allowing the monopolist to exploit its position.

    Government Initiatives taken in India for similar line:

    The Draft Competition Bill 2024: The Ministry of Corporate Affairs’ Bill prevents giant tech companies/ Systemically Significant Digital Enterprises (SSDEs) from participating in anti-competitive practices.

    • The Bill imposes restrictions on SSDEs, barring them from favouring their own products and services, and from using or sharing users’ personal data without their consent.
    • Big tech companies have objected to the Bill because the compliance burdens would shift focus from innovation and research.

    Way forward: 

    • Encouraging Innovation: Governments and regulatory bodies should support the development of alternative search engines and platforms through incentives, grants, and support for startups.
    • Banning Exclusive Agreements: Prohibit exclusive distribution agreements that make one product or service the default, ensuring that consumers have a choice and that competitors can fairly compete.

    Mains question for practice: 

    Q Discuss the significance of India’s Competition Act, 2002 in regulating anti-competitive practices and promoting a fair market environment. 10M

  • Hidden dangers of irrational use of antibiotics on microbiome    

    Why in the news?

    While vital for treating infections, antibiotics can disrupt the microbiome by indiscriminately killing both harmful pathogens and beneficial gut bacteria, especially broad-spectrum types.

    Various roles played by Antibiotics (Applications):  

     

    Treatment of Infections

    Antibiotics are essential for treating bacterial infections, significantly reducing mortality rates associated with infectious diseases

    For example, penicillin and other antibiotics, the mortality rate from strep throat dropped dramatically from 1% to less than 0.1%.

    Preventing Disease Spread 

    Treating bacterial infections, antibiotics can prevent the spread of disease to other individuals

    For instance, during the 2009 H1N1 influenza pandemic, antibiotics were used to treat secondary bacterial pneumonia, which was a major cause of death.

    Reducing Complications

    Antibiotics can reduce the risk of serious complications from bacterial infections.

    For instance, In the case of urinary tract infections (UTIs), untreated infections can lead to kidney damage or life-threatening conditions like sepsis. However, with prompt antibiotic treatment, the risk of complications is greatly reduced

    Supporting Medical Procedures

    Antibiotics are used prophylactically to prevent infections before certain medical procedures

    For example in surgery

    Concerning Aspects of Antibiotic Use

    • Dysbiosis: The disruption of the microbiome, known as dysbiosis, can lead to severe health issues, including inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). 
    • Increased Infection Risk: Antibiotics can reduce colonization resistance, which is the microbiome’s ability to prevent pathogenic microorganisms from establishing infections. This reduction increases the risk of infections by harmful bacteria, such as Clostridioides difficile.
    • Antimicrobial Resistance (AMR): Overuse of antibiotics contributes to the development of antimicrobial resistance, making it more challenging to treat infections. The global crisis of antibiotic resistance is exacerbated by the enrichment of antibiotic resistance genes within the gut microbiota due to antibiotic exposure.
    • Long-term Health Consequences: Repeated antibiotic use can prevent full recovery of the microbiome, leading to chronic health issues. Research shows that children who receive multiple courses of antibiotics are at higher risk for developing conditions like IBD later in life.
    • Impact on Other Organ Systems: Dysbiosis can affect various organ systems through gut-organ axes, influencing conditions such as mental health disorders (via the gut-brain axis), liver diseases (via the gut-liver axis), and skin conditions (via the gut-skin axis) due to altered immune responses and increased permeability.

    Government initiatives: 

    1. The Indian Council of Medical Research (ICMR) has initiated an antibiotic stewardship program (AMSP) on a pilot basis in 20 tertiary care hospitals across India to control the misuse and overuse of antibiotics in hospital wards and ICUs.
    2. ICMR collaborated with the Indian Council of Agriculture Research, Department of Animal Husbandry, Dairy and Fisheries, and the Drugs Controller General of India (DCGI) to ban the use of Colistin as a growth promoter in animal feed in poultry.
    3. The Government of India launched the National Action Plan on Antimicrobial Resistance (NAP-AMR) in April 2017, focusing on a One Health approach.

    Way forward: 

    • Antibiotic Stewardship Programs: Implement and promote antibiotic stewardship programs in healthcare settings to ensure antibiotics are prescribed only when necessary and with the appropriate dosage and duration.
    • Probiotic Supplementation: Encourage the use of probiotics alongside antibiotic treatments to help maintain a healthy microbiome and mitigate the risks of dysbiosis and related health issues.

    Mains PYQ: 

    Q Can overuse and free availability of antibiotics without Doctor’s prescription, be contributors to the emergence of drug-resistant diseases in India? What are the available mechanisms for monitoring and control? Critically discuss the various issues involved. (2014)

  • Cold War nuke tests light up a bug in present-day climate models  

    Why in the News?

    A new calculation suggests that climate models might be overestimating how long plants keep carbon before releasing it as per the recent study published in Science by an international research team.

    Study by an International Team of Researchers:

    • A recent study published in Science by an international research team suggests that plants absorb more CO2 from the atmosphere than previously thought but release it back into their surroundings sooner than expected.
    • Researchers utilized climate models to analyze the impact of radiocarbon (carbon-14) from nuclear bomb tests on the carbon cycle. They tracked changes in radiocarbon levels in the atmosphere and how it was absorbed by plants during photosynthesis.
    • The study estimates that plants store around 80 billion tonnes of carbon per year, primarily in leaves and finer roots, which is higher than previous estimates of 43-76 billion tonnes. This indicates that plants may be cycling carbon through the atmosphere and soil more rapidly than previously thought.

    Study from the Relics of the Cold War:

    • The nuclear bomb tests conducted during the Cold War inadvertently provided scientists with valuable data for climate research.
      • The tests released significant amounts of radiocarbon into the atmosphere, allowing researchers to study its movement and absorption by vegetation.
    • The presence of radiocarbon in the atmosphere serves as a marker for understanding carbon dynamics.
      • The study analyzed the radiocarbon levels before and after the 1963 Limited Test Ban Treaty, which halted atmospheric nuclear testing, providing insights into how carbon is cycled between the atmosphere and vegetation.
    • The study highlights that many climate models have not incorporated radiocarbon data, which could lead to inaccuracies in predicting carbon cycling and its impact on climate change.
      • Only one model, the Community Earth System Model 2, has accounted for radiocarbon, but it predicted lower absorption levels than the study found.

    How the Whole System is Cycling Faster?

    • Accelerated Carbon Exchange: The researchers concluded that the entire carbon cycle is operating faster than previously understood.
      • This means that while plants absorb more CO2, they also release it back into the atmosphere more quickly, leading to a more dynamic and less stable carbon storage system.
    • Implications for Climate Mitigation: The findings suggest that strategies relying on plant carbon sequestration to offset fossil fuel emissions may need to be reevaluated.
      • If plants are releasing carbon sooner than expected, the potential for mitigating climate change through natural carbon sinks could be less effective than previously thought.

    Way forward: 

    • Incorporate Radiocarbon Data: Integrate radiocarbon data into existing and future climate models to more accurately predict carbon cycling and the role of vegetation in carbon sequestration. This will lead to more reliable forecasts of climate change impacts and inform better policy decisions.
    • Develop Dynamic Carbon Cycle Models: Improve models to account for the faster carbon cycling observed, ensuring they reflect the actual pace at which carbon is absorbed and released by plants. This will help in refining strategies for climate mitigation.
  • What is the Nankai Trough?  

    Why on the News?

    Japanese authorities have warned its citizens of a ‘megaquake’ and large tsunamis along the Nankai Trough.

    What is the Nankai Trough?

    • The Nankai Trough is an extensive subduction zone, nearly 900 km long.
    • It is the place of collision of the Eurasian Plate over the Philippine Sea Plate.
    • This trough has a history of producing large earthquakes approximately every 100 to 150 years.
    • The most recent Nankai Trough quake happened in 1946 with magnitude 8.0 tremor and 6.9 metre tsunami, killing 1,330 people.

    Potential for a Megaquake: 

    • Japan’s researchers estimated in January 2022 that there is a roughly 70% chance of a magnitude 8-9 megaquake striking the Nankai Trough within next 30 years.
    • Such a quake could affect a vast region stretching from central Shizuoka, about 150 km south of Tokyo, to southwestern Miyazaki.
