Sabarimala Case and the Debate on Religious Diversity: A Constitutional Perspective
1. Why in News?
- The ongoing proceedings in the Supreme Court of India regarding the Sabarimala Temple entry issue have reignited a fundamental constitutional debate on who defines religion and its essential practices.
- The Union Government has strongly argued that imposing rigid judicial definitions on religious practices may suppress the inherent plurality and diversity of Hinduism. This comes in the context of review petitions and larger constitutional questions referred to a bigger bench after the 2018 judgment that allowed women of all ages to enter the Sabarimala Temple. The case has become a flashpoint on the balance between individual rights (Articles 14 and 25) and religious freedom and autonomy (Articles 25 and 26).
2. Background of the Sabarimala Case
- The controversy centres on the traditional restriction at the Sabarimala Temple in Kerala, where women aged 10–50 were barred from entry based on custom and belief that the presiding deity (Lord Ayyappa) is a Naisthika Brahmachari (eternal celibate).

- In Indian Young Lawyers Association v. State of Kerala (2018), a 4:1 Constitution Bench ruled that:
- The exclusion violated Article 14 (equality) and Article 25 (freedom of religion).
- The practice was not an “essential religious practice” and could not override fundamental rights of women.
- Review petitions led to the matter being referred to a larger bench to examine broader questions, including the scope of judicial intervention in religious matters and the doctrine of essential religious practices.
3. Government’s Stand: Diversity Over Uniform Definition
The Centre has submitted that:
- Hinduism is not monolithic: It comprises diverse sects, beliefs, rituals, and traditions with no single founder, uniform doctrine, or central authority.
- Imposing a rigid judicial definition of “essential religious practices” risks undermining this pluralism.
- Courts should exercise restraint and avoid becoming arbiters of faith, as this may disturb long-standing community traditions and amount to judicial overreach.
4. Key Constitutional Provisions Involved
- Article 19(1)(a): Freedom of speech and expression (extended to include right to access religious places in some interpretations).
- Article 25: Freedom of conscience and right to profess, practise, and propagate religion (subject to public order, morality, health, and other provisions).
- Article 26: Rights of religious denominations to manage their own affairs in matters of religion.
- Article 14: Equality before law — central to challenges against exclusionary practices.
5. Doctrine of Essential Religious Practices (ERP)
- Developed by the Supreme Court to determine which practices are protected under Articles 25 and 26.
- Courts decide whether a practice is “essential” to a religion based on its core tenets.
- Criticism: The doctrine leads to subjective judicial interpretation, potential overreach, and erosion of religious autonomy. The current case questions whether the judiciary should continue applying this doctrine or defer more to community practices.
6. Core Issues in the Debate
- Who defines religion? — State/Judiciary vs Religious communities.
- Individual rights vs Collective faith — Gender justice vs traditional customs.
- Constitutional morality vs Social practices — Progressive interpretation vs cultural continuity.
7. Significance and Implications
- Legal: May lead to redefinition or refinement of the ERP doctrine and set limits on judicial intervention in religious matters.
- Social: Touches the broader debate on gender justice, tradition, and reform within religions.
- Political: Highlights Centre–Judiciary dynamics and the role of the State in religious affairs.
- Constitutional: Tests the limits of “principled distance” in Indian secularism — balancing religious freedom with fundamental rights.
8. Way Forward Suggested
- Develop clearer, more objective guidelines for applying the ERP doctrine.
- Ensure judicial restraint and sensitivity while protecting fundamental rights.
- Promote dialogue between communities, religious denominations, and constitutional institutions.
- Maintain a delicate balance between individual dignity, gender equality, and collective religious freedom.

Shellear Fish Climbs 15-Metre Waterfall in Congo: Rare Adaptation in Extreme Environment
1. Why in News?
- Scientists have confirmed a remarkable behaviour in the Shellear fish (Parakneria thysi): it can climb vertical waterfalls up to 15 metres (50 feet) tall in the Democratic Republic of the Congo (DRC).
- This discovery, reported in early April 2026, highlights one of the most extraordinary adaptations in the animal kingdom. The tiny fish uses specialised anatomical features to scale the Luvilombo Falls on the Luvilombo River in the upper Congo Basin. Researchers believe the climbing helps the fish reach upstream areas with better living conditions, less competition, and fewer predators.
2. About Shellear Fish (Parakneria thysi)
- Scientific Name: Parakneria thysi

- Common Name: Shellear fish (due to its shell-like appearance or habitat).
- Habitat: Benthopelagic freshwater species found in the upper Congo Basin, particularly around the Luvilombo Falls on the Luvilombo River.
- Size: Tiny fish, typically 37–48 mm in length, growing up to a maximum of around 96 mm.
- Unique Adaptation for Climbing:
- Possesses tiny, hook-like projections on specialised pads on its pectoral and pelvic fins.
- Has hypertrophied (enlarged) muscles that allow it to support its body weight while climbing vertical rock surfaces against strong water flow.
- This enables the fish to “walk” or crawl up steep, wet rock faces in fast-flowing waterfalls.
3. Why Do They Climb?
Researchers suggest the primary reasons are:
- To reach upstream habitats with more suitable living conditions.
- To access areas with less competition for food and breeding grounds.
- To escape predators that are more abundant in downstream pools.
This behaviour is an excellent example of evolutionary adaptation to extreme environments.
4. Threats to the Species
The study identified two major human-induced threats:
- Illegal fishing using fine-mesh mosquito nets, which easily catch these small fish.
- Water extraction for irrigation, which in some years has significantly depleted the flow of the Luvilombo River, affecting the fish’s habitat and climbing routes.
5. Significance of the Discovery
- Demonstrates the incredible biodiversity and adaptive capabilities of species in the Congo Basin, one of the world’s most important freshwater ecosystems.
- Adds to the growing list of “climbing” or “amphibious” fish (similar to mudskippers or climbing perch) that challenge conventional understanding of fish locomotion.
- Highlights the urgent need for conservation of fragile riverine ecosystems facing anthropogenic pressures.

Chief Election Commissioner: Appointment, Powers, Removal Process and Recent Developments
1. Why in News?
- Notices submitted by Opposition MPs in both Houses of Parliament seeking the removal of Chief Election Commissioner Gyanesh Kumar were rejected by the Rajya Sabha Chairman and Lok Sabha Speaker.
- The presiding officers held that the allegations did not meet the high constitutional threshold of “proved misbehaviour or incapacity” required under Article 324(5). The notices, signed by 63 Rajya Sabha and 130 Lok Sabha members, contained seven charges, but were found to lack sufficient evidence or prima facie merit. Some issues were already under judicial consideration or had been adjudicated earlier. This episode has once again brought the appointment, independence, and removal process of the CEC into focus.
2. Office of the Chief Election Commissioner
- The Chief Election Commissioner (CEC) is the head of the Election Commission of India (ECI), a constitutional body established under Article 324 of the Constitution.

- The ECI is responsible for the superintendence, direction, and control of the conduct of free and fair elections to:
- Parliament
- State Legislatures
- Offices of the President and Vice-President
3. Appointment of the CEC
- Appointed by the President of India.
- As per the Chief Election Commissioner and Other Election Commissioners Act, 2023, the appointment is made on the recommendation of a Selection Committee consisting of:
- Prime Minister (Chairperson)
- Leader of Opposition in the Lok Sabha
- One Union Cabinet Minister (nominated by the Prime Minister)
This mechanism was introduced to bring greater transparency and balance in the selection process.
4. Tenure and Service Conditions
- Tenure: Six years or until the age of 65 years, whichever is earlier.
- Service conditions cannot be varied to the disadvantage of the CEC after appointment, ensuring functional independence.
5. Powers and Functions of the CEC/ECI
Under Article 324, the Election Commission (headed by the CEC) has wide-ranging powers, including:
- Preparation and revision of electoral rolls.
- Conduct of free and fair elections.
- Enforcement of the Model Code of Conduct.
- Monitoring of election expenditure.
- Plenary powers to act in areas where law is silent, to ensure the integrity of the electoral process (affirmed by the Supreme Court).
6. Removal Process of the CEC
- The removal of the CEC is similar to that of a Supreme Court Judge.
- Under Article 324(5), the CEC can be removed by the President only on grounds of proved misbehaviour or incapacity.
- The process requires:
- A motion passed in both Houses of Parliament.
- Special majority: Majority of the total membership of the House and two-thirds of the members present and voting.
This high threshold protects the office from arbitrary or politically motivated removal and safeguards institutional independence.
7. Recent Rejection of Removal Notices (2026)
- Allegations included claims of biased appointment, differential treatment, refusal to share electoral data, and issues related to the Special Intensive Revision (SIR) of electoral rolls.
- The presiding officers ruled that:
- Many allegations lacked evidence.
- Some were already under judicial review.
- Others did not meet the constitutional standard of “misbehaviour”.
- The decision reinforced the high bar required for initiating removal proceedings against the CEC.

Artemis II Mission Sets New Record: Crewed Spacecraft Travels 406,771 km from Earth
1. Why in News?
- During the Artemis II mission — NASA’s first crewed flight under the Artemis programme — the four astronauts aboard the Orion spacecraft travelled approximately 406,771 km from Earth.
- This distance, achieved while looping around the far side of the Moon, set a new record for the farthest human spaceflight in history. The previous record was held by Apollo 13 (1970), which went farther only due to an emergency trajectory deviation. In contrast, Artemis II’s distance was a planned outcome of its free-return trajectory, not the mission’s primary objective.
2. About Artemis II Mission
- Type: Crewed lunar flyby mission (not a landing mission).
- Spacecraft: Orion (multi-purpose crew vehicle).
- Crew: Four astronauts (first crewed Artemis flight after the uncrewed Artemis I).
- Duration: Approximately 10 days.
- Main Goal: To test the Orion spacecraft’s systems, life support, and overall performance in deep space conditions with humans on board, paving the way for future lunar landings and a sustainable Moon base.
3. Flight Path: Free-Return Trajectory
Unlike Apollo 8, which entered a circular lunar orbit, Artemis II follows an elliptical free-return trajectory: 
- High Earth Orbit (HEO) Phase: Orion first enters a highly elliptical orbit around Earth, reaching up to ~74,000 km. This 42-hour phase allows astronauts to test critical systems (environmental control, life support, etc.). If any issue arises, the spacecraft remains within Earth’s gravity well, enabling a quick abort and safe return.
- Translunar Slingshot Phase: After system checks, Orion is propelled toward the Moon. It passes approximately 10,300 km beyond the lunar far side. The Moon’s gravity captures the spacecraft and slingshots it back toward Earth without requiring major engine burns for the return journey.
Advantages of Free-Return Trajectory:
- Safety: Even if main engines fail, the spacecraft will naturally return to Earth due to lunar gravity assist.
- Fuel Efficiency: Minimises the need for heavy deceleration and acceleration burns.
- Propellant Reserve: Saves fuel for contingencies and emergency manoeuvres.
4. Significance of the Record
- Artemis II has set a new benchmark for human spaceflight distance (406,771 km), surpassing the Apollo-era record under planned mission parameters.
- Demonstrates the reliability of the Orion spacecraft for deep-space human missions.
- Provides critical data on crew performance, life-support systems, and spacecraft behaviour in the lunar environment.
- Marks a major step toward NASA’s long-term goal of sustainable human presence on the Moon and eventual Mars missions.
5. Next Steps in the Artemis Programme
- Artemis II is primarily a test flight focused on validating Orion’s capabilities with crew.
- Success will clear the path for Artemis III (planned crewed lunar landing) and subsequent missions to establish a lunar base (Artemis Base Camp).
- The programme aims to land the first woman and first person of colour on the Moon and use the lunar surface as a stepping stone for deeper space exploration.
