From UPSC perspective, the following things are important :
Prelims level: Collegium system, NJAC
Mains level: Not Much
Central Idea
- The Supreme Court Collegium, led by Chief Justice of India D. Y. Chandrachud, has recommended new Chief Justices for seven major High Courts in India.
- The recommendations focus on criteria such as seniority, regional representation, and gender diversity.
What is Collegium System?
- The Collegium of judges is the Indian Supreme Court’s invention.
- It does not figure in the Constitution, which says judges of the Supreme Court and High Courts are appointed by the President and speaks of a process of consultation.
- In effect, it is a system under which judges are appointed by an institution comprising judges.
- After some judges were superseded in the appointment of the CJI in the 1970s, and attempts made subsequently to effect a mass transfer of High Court judges across the country.
- Hence there was a perception that the independence of the judiciary was under threat. This resulted in a series of cases over the years.
Evolution: The Judges Cases
- First Judges Case (1981) ruled that the “consultation” with the CJI in the matter of appointments must be full and effective.
- However, it rejected the idea that the CJI’s opinion, albeit carrying great weight, should have primacy.
- Second Judges Case (1993) introduced the Collegium system, holding that “consultation” really meant “concurrence”.
- It added that it was not the CJI’s individual opinion, but an institutional opinion formed in consultation with the two senior-most judges in the Supreme Court.
- Third Judges Case (1998): On a Presidential Reference for its opinion, the Supreme Court, in the Third Judges Case (1998) expanded the Collegium to a five-member body, comprising the CJI and four of his senior-most colleagues.
Functions of the Collegium
(1) Appointment of CJI
- The President of India appoints the CJI and other Supreme Court judges.
- The outgoing CJI recommends his successor, and the appointment is typically made based on seniority, following the controversy of the 1970s.
- The Union Law Minister forwards the recommendation to the Prime Minister, who then advises the President on the appointment.
(2) Appointment of Other SC Judges
- The proposal for appointing other judges to the Supreme Court is initiated by the CJI.
- The CJI consults other members of the Collegium, as well as the senior-most judge from the High Court to which the recommended person belongs.
- The opinions of the consultees must be recorded in writing and included in the file.
- The Collegium sends the recommendation to the Law Minister, who forwards it to the Prime Minister for the President’s advice.
(3) Appointment of High Court Judges
- Chief Justices (CJs) of High Courts are appointed based on the policy of having Chief Justices from outside the respective states. The Collegium makes the final decision on their elevation.
- The appointment of High Court judges is recommended by a Collegium consisting of the CJI and two senior-most judges.
- The Chief Justice of the High Court concerned initiates the proposal in consultation with two senior-most colleagues.
- The recommendation is then sent to the Chief Minister, who advises the Governor to forward the proposal to the Union Law Minister.
(4) Transfer Recommendations by the Collegium
- The Collegium is also responsible for recommending transfers of Chief Justices and other judges.
- Article 222 of the Constitution allows for the transfer of judges from one High Court to another.
- When a Chief Justice is transferred, a replacement must be simultaneously appointed for the concerned High Court. An acting Chief Justice can be appointed for a maximum of one month.
- In transfer matters, the CJI’s opinion is determinative, and the consent of the judge being transferred is not required.
- However, the CJI should consider the views of the Chief Justice of the concerned High Court and one or more Supreme Court judges who are in a position to provide their opinions.
- All transfers must be made in the public interest, aiming for the betterment of the administration of justice.

From UPSC perspective, the following things are important :
Prelims level: Greedflation
Mains level: NA
Central Idea: Greedflation
- The concept of “Greedflation” has emerged, suggesting that corporate greed for higher profits is a significant cause of the high inflation experienced in the United States since the pandemic.
- Proponents of this theory argue that increased corporate profit margins have contributed to rising prices.
- However, many economists question the validity of this narrative and offer alternative explanations for inflation.
Inflation and Business Pricing
- Pricing Dynamics: Businesses set prices based on consumer willingness to pay, aiming to maximize profits.
- Consumer Influence: Consumers ultimately determine the market price through their buying decisions.
- Market Competition: Businesses unable to sell products at high prices must lower prices to clear their stock.
Inflation as a Macro-Level Phenomenon
- Widespread Price Rise: Inflation refers to a general increase in the price level across the economy.
- Corporate Influence on Prices: Corporations can impact overall prices by reducing supply, but there is no evidence of deliberate output reduction.
- Monetary Policy and Inflation: The expansionary monetary policy of the U.S. Federal Reserve, combined with supply-chain disruptions, explains recent inflation.
Rising Corporate Profit Margins
- Rising Costs vs. Consumer Prices: Input costs have risen faster than consumer goods prices, leading to unexpected profit margin growth.
- Corporate Profits vs. Wider Economy: Large corporations may have benefited from smaller business closures during the pandemic, but they represent a small portion of the overall economy.
- Profit Margins and Inflation: Rising profit margins do not directly cause high inflation; prices are determined by buyers, not sellers.
Critique of “Greedflation” as Cost-Push Inflation
- Cost-Push Inflation Comparison: Greedflation is likened to cost-push inflation theories that attribute price increases to rising input costs.
- Consumer Influence on Costs: The cost of inputs is indirectly determined by consumers through competitive bidding in the market.
Conclusion
- The notion of greedflation, attributing high inflation to corporate greed, lacks support from economists who emphasize the influence of consumer behaviour and macroeconomic factors.
- While rising profit margins of corporations may indicate market dominance, they do not directly drive inflation.
- Instead, factors such as monetary policy and supply disruptions better explain the recent inflationary pressures experienced in the United States.

Prelims level: Har Ghar Jal Initiative
Mains level: NA
Central Idea
- The Har Ghar Jal initiative, part of the Jal Jeevan Mission, aims to provide potable water connections to all rural households in India by 2024.
- However, multiple sources and data analysis indicate that the initiative is likely to fall short of its target, with only 75% of village homes expected to have drinking water taps by April 2024.
Har Ghar Jal Initiative: A quick recap
- Har Ghar Jal (translation: Water to Every Household) is a scheme initiated by the Ministry of Jal Shakti under Jal Jeevan Mission in 2019.
- It aimed to provide tap water to every rural household by 2024.
- Finance Minister announced the scheme in 2019 Union budget.
- In August 2022, Goa and Dadra and Nagar Haveli and Daman and Diu became the first ‘Har Ghar Jal’ certified State and UT respectively with 100% tap-water access.
- As of January 2023, other states and UTs Gujarat, Puducherry and Telangana have also achieved 100% tap-water access.
- Since its inception, the scheme has significantly improved household clean tap water availability in India.
Challenges Faced by the Initiative
- Delayed Progress: The COVID-19 pandemic and a lack of qualified manpower in states have contributed to the delayed implementation of the scheme.
- Shortages of Essential Materials: The ongoing Russia-Ukraine war resulted in major shortages of steel and cement, crucial for manufacturing and connecting metal pipes, leading to delays and price revisions.
- Manpower Shortage: Some states faced challenges in finding skilled workers to construct tanks, cisterns, and water connections of acceptable quality.
- State-Specific Issues: Certain states, such as Rajasthan, face challenges in ensuring the availability of water, while West Bengal and Kerala struggle with water contamination issues.
- Certification Gap: While the states report high coverage figures, there is a significant gap between reported and verified connections.
Expectations and Progress
- Revised Expectations: The officials now expect about 75% of households to be covered by March 2024 and 80% by December 2024.
- Work Yet to Begin: Around one crore households (5% of the total) have not even begun work under the scheme.
- Timeframe Challenges: Connecting all households in villages that already have access to water sources takes an average of eight months, making it unlikely to finish in some places before 2025-26.
Political Factors and Connection Status
- Political Angle: Some states, like Bihar and Telangana, did not rely on central funds and did not certify their connection status due to political considerations.
- Significance of Certification: “Har Ghar Jal” villages certified as 100% compliant prominently display the images of the Prime Minister and Chief Minister, especially if Central funds were used.

Prelims level: Hul Diwas, Santhal Revolt
Mains level: NA
Central Idea
- Prime Minister commemorated Hul Diwas, honoring the sacrifice of Santhals in their fight against British colonial authorities.
What is Hul Divas?
- The Santhal rebellion, known as the ‘Hul,’ was an organized war against colonialism led by the Santhals, who stood against various forms of oppression inflicted upon them by the British.
- This article explores the significance of the Santhal rebellion, their identity, the reasons behind the Hul, its organization, and its lasting impact.
Santhals and their Migration
- The Santhal people, or Santhalis, migrated from the Birbhum and Manbhum regions of Bengal to modern-day Santhal Pargana.
- The British relocated the Santhals to the forested area of Damin-i-Koh, dislodging the indigenous Pahariya community, as part of their revenue collection strategy.
- However, the Santhals faced severe colonial oppression, including exploitative moneylenders and the police.
Reasons behind the Hul
- The Santhals rebelled against the British due to extortions, oppressive extractions, dispossession of property, false measurements, and other illegalities.
- Tribal councils and meetings discussed the possibility of rebellion, leading to a massive assembly of over 6,000 Santhals on June 30, 1855, marking the beginning of the rebellion.
- Led by Sidhu and Kanhu, the Santhals rose against the British, attacking symbols of colonial rule and executing moneylenders and zamindars.
Organization of the Hul
- Contrary to popular belief, the Hul was a well-planned and organized political war.
- Evidence from documents and historical accounts reveals preparations such as guerrilla formations, military teams, detectives, secret bases, logistics, and a network of message carriers for coordination.
- Non-Adivasi Hindu castes also participated in the rebellion, highlighting the diverse nature of the movement.
Lesser-Known Facts about the Hul
- The rebellion saw participation from 32 communities, both tribals and non-tribals, challenging the notion that it was solely a Santhal rebellion.
- Phulo-Jhano, two sisters, led an army of 1,000 women, playing crucial roles in providing food supply, gathering information, and attacking British camps.
- The East India Company’s army was defeated twice during the rebellion, debunking the belief that they were invincible.
British Narratives and Accounts
- British reports and personal narratives provide insights into the causes of the Santhal rebellion, including excessive taxation, falsehood, and negligence of British officials, extortion by moneylenders, corruption, and oppression.
- The sufferings inflicted by moneylenders or ‘mahajans’ on the Santhals were a primary cause of the uprising.
Accounts from Prisoners and Divine Intervention
- Similar to other tribal uprisings, accounts exist of deities appearing in dreams or before the rebels.
