The Central Armed Police Forces (General Administration) Bill, 2026

Source:  TP

Subject:   Role of Civil Services in a Democracy

Context: The Central Government introduced the Central Armed Police Forces (General Administration) Bill, 2026 in the Rajya Sabha.

About The Central Armed Police Forces (General Administration) Bill, 2026:

What it is?

• The Bill is a regulatory framework designed to govern the recruitment, promotion, and service conditions of Group ‘A’ General Duty Officers and other personnel within specified CAPFs.
• It seeks to provide legislative clarity to the historical practice of IPS officers leading these forces, ensuring that the unifying link between the Union and the States remains structurally intact.

Key Features of the Bill:

• Scope of Application: Applies to five primary CAPFs: CRPF, BSF, CISF, ITBP, and SSB. The government can add more forces via notification.
• Rule-Making Power: Empowers the Central Government to frame rules for recruitment, deputation, and service conditions, overriding any existing laws or court orders.
• Mandatory IPS Deputation: Explicitly earmarks high-level posts for IPS officers:
  • 50% of Inspector General (IG) posts.
  • Minimum 67% of Additional Director General (ADG) posts.
  • 100% of Special Director General (SDG) and Director General (DG) posts.
• Protection of Benefits: Saves and continues all existing financial benefits granted to Group ‘A’ officers prior to the Act.
• Personnel Coverage: Includes Group ‘A’ executive officers (Assistant Commandant and above), IPS officers on deputation, and Army officers on deputation or re-employment.

Need for Such Changes:

• Inter-Agency Coordination: IPS officers provide a bridge between the Union’s armed forces and State police departments.

Example: Since senior operational posts in States are held by IPS officers (ADGs/SDGs), having them in CAPF leadership ensures seamless coordination during internal security crises.

• Maintaining Force Character: The Bill institutionalizes the unique character of CAPFs as forces that assist civil power.

Example: The Supreme Court noted in Sanjay Prakash (2025) that IPS presence is vital to maintain the functional ethos and administrative requirements of these forces.

• National Integration: Reflects Sardar Patel’s vision of the IPS as a unifying link across the federal structure.

Example: IPS officers bring field experience from various States, giving them a broader strategic vision required to lead national border and industrial security forces.

• Legislative Supremacy: Clarifies that service policy falls under the domain of the Executive and Legislature, not the Judiciary.

Example: The Bill rectifies the judicial overreach where courts previously directed a reduction in IPS deputation quotas, which is essentially a policy matter.

• Camaraderie and Training: Mandatory stints at the Centre for IPS officers foster better relationships with cadre officers.

Example: As per the January 2026 MHA guidelines, mandatory two-year central stints for IPS IGs will help cement operational bonds with CAPF-cadre subordinates.

Challenges Associated:

• Stagnation of Cadre Officers: High-level IPS quotas limit the career progression of GAGDOs (Group A General Duty Officers).

Example: Direct-entry CAPF officers often wait decades for promotions, as the top tiers (ADG, SDG, DG) are now legally reserved for IPS officers.

• Judicial Conflict: The Bill appears to directly undo recent Supreme Court directions.

Example: It overrides the Sanjay Prakash (2025) ruling which instructed the government to progressively reduce IPS deputation at the IG level within two years.

• Parachuting Perception: There is perceived resentment among cadre officers who feel IPS officers lack specific force-specific expertise.

Example: Critics argue that an officer who has spent a career in district policing may not be immediately suited for specialized roles like border guarding (BSF) or industrial security (CISF).

• Federal Friction: While intended as a link, the dominance of IPS can sometimes lead to friction between Central command and State requirements.

Example: Dependence on a single service for top leadership can lead to service-specific biases in resource allocation and operational strategy.

• Legal Challenges: The notwithstanding clause may be challenged on the grounds of constitutional validity.

Example: Opponents may argue that overriding court orders regarding Organised Group A Service (OGAS) status violates the principle of judicial review.

Way Ahead:

• Timely Cadre Reviews: To mitigate resentment, the government must conduct regular cadre reviews to increase the total number of posts, ensuring growth for both IPS and cadre officers.
• Balanced Deputation: While maintaining IPS at the top, the government could explore increasing the share of cadre officers in specialized technical or training wings.
• Specialized Induction: IPS officers being deputed to CAPFs should undergo mandatory force-induction training to understand the specific operational nuances of the BSF, CRPF, etc.
• Strengthening OGAS Rights: Ensuring that the financial and administrative benefits of being an Organised Group A Service are fully realized by CAPF cadre officers.

Conclusion:

The CAPF (General Administration) Bill, 2026 is a decisive step toward stabilizing the leadership structure of India’s internal security forces by codifying the role of the IPS. While it addresses the need for a unified command and federal coordination, the government must simultaneously address the promotion aspirations of the dedicated CAPF cadre.

Custodial Death in India

Source:  DH

Subject:  Governance

Context: Despite recorded custodial deaths of over five persons per day in India, a comprehensive anti-torture law remains elusive, with the most recent legislative attempt having lapsed in Parliament.

• Current discussions highlight India’s failure to ratify the UN Convention Against Torture (UNCAT) and the lack of a legal definition for torture in the Indian Penal Code.

About Custodial Death in India:

What it is?

• Custodial death refers to the death of a person while in the custody of law enforcement agencies (Police or Judicial/Prison custody). It is often the result of excessive use of force, torture, medical negligence, or poor conditions of confinement, representing one of the most severe violations of the Fundamental Right to Life and Dignity under Article 21 of the Indian Constitution.

Data & Stats on Custodial Death:

• Frequency: India recorded 11,419 custodial deaths between 2016-17 and 2021-22, averaging more than five deaths every day.
• Low Conviction Rate: National Crime Records Bureau (NCRB) data shows that from 2018 to 2021, not a single police official was convicted for custodial deaths.
• Under-reporting: While the NHRC receives thousands of complaints, a vast majority of staged encounters or deaths in rural lockups go unreported as custodial torture.
• International Standing: India is one of the few major democracies that has signed (1997) but not ratified the UN Convention Against Torture (UNCAT).
• Demographics: A disproportionate number of custodial victims belong to marginalized communities, including Dalits, Adivasis, and religious minorities.

Factors Leading to Rising Custodial Death:

• Culture of Impunity: Police officials often feel protected by institutional support and slow legal processes.

Example: The lack of a single conviction between 2018 and 2021 emboldens officials to use third-degree methods without fear of consequences.

• Coercive Interrogation Protocols: Extracting confessions is often treated as the primary method of solving crimes.

Example: Despite confessions to police being inadmissible in court, they are still used to discover evidence, leading to physical abuse during interrogation.

• Institutional Whitewashing: Internal inquiries often protect the accused rather than seeking the truth.

Example: Departmental inquiries are frequently conducted by colleagues of the accused, leading to clean chits and the suppression of transparent autopsy reports.

• Lack of Specialized Legislation: The absence of a specific Anti-Torture Law creates a legal vacuum.

Example: The IPC does not define torture, and existing sections (330, 331) only cover physical hurt for confession, leaving out mental agony and extra-judicial punishments.

• Normalization of Violence: Public and political narratives sometimes glorify instant justice or encounter culture.

Example: High-handed police action often receives tacit social approval, which discourages victims’ families from pursuing long, expensive legal battles against the state.

Supreme Court Judgments on Custodial Death:

• D.K. Basu vs. State of West Bengal (1997): The landmark judgment that laid down 11 mandatory guidelines for arrest and detention to prevent custodial torture.
• Nilabati Behera vs. State of Orissa (1993): Established that the state has a strict liability to pay compensation for the violation of the right to life in custody.
• Prakash Singh vs. Union of India (2006): Directed the setting up of a Police Complaints Authority (PCA) at the state and district levels to look into complaints of serious misconduct.
• Sube Singh vs. State of Haryana (2006): Rebalanced the state’s power by affirming that the sovereign immunity defense does not apply in cases of custodial torture.
• Paramvir Singh Saini vs. Baljit Singh (2020): Mandated the installation of CCTV cameras and recording equipment in all police stations across the country to ensure transparency.

Challenges Associated:

• Definitional Gaps: The current legal understanding of torture is too narrow.

Example: The lapsed 2010 Bill ignored mental torture and non-interrogation abuse, which are central to the UNCAT definition.

• Statutory Limitations: Filing complaints is often hindered by short windows of time.

Example: Previous draft bills proposed a six-month limitation period, which is insufficient for victims who are often too traumatized or intimidated to act immediately.

• Procedural Lapses: Crucial steps like independent autopsies are often bypassed.

Example: Without a binding legal obligation for a transparent, third-party autopsy, evidence of physical abuse is easily erased or altered.

• Weak Oversight: Bodies like the NHRC often lack proactive investigative teeth.

Example: The NHRC seldom pursues independent investigations into torture, often relying on the same police reports that are under question.

• Resource Constraints: Most police stations lack the infrastructure to comply with judicial mandates.

Example: The Supreme Court’s order to install functional CCTVs remains unfulfilled in thousands of stations due to budget and maintenance issues.

Way Ahead:

• Ratify UNCAT: India must move beyond being a signatory and ratify the UN Convention Against Torture to align domestic laws with global human rights standards.
• Enact Comprehensive Legislation: Pass a dedicated Anti-Torture Act that defines torture expansively, including mental and psychological abuse.
• Independent Investigation Agency: Create an independent oversight body, separate from the police, to investigate all cases of custodial death and torture.
• Strict Accountability: Implement command responsibility where senior officers are held accountable for the actions of their subordinates in lockups.
• Sensitization Training: Revamp police training to focus on scientific interrogation techniques (like forensic DNA and data analysis) rather than physical coercion.

Conclusion:

Torture is a relic of a colonial penal culture that has no place in a modern constitutional democracy. The rising toll of custodial deaths is a stark reminder that judicial guidelines alone cannot substitute for a robust, central anti-torture law. Until accountability is institutionalized and the dignity of detainees is safeguarded by statute, the promise of Article 21 will remain unfulfilled for the most vulnerable.

Superior Kerosene Oil (SKO)

Source:  News on Air

Subject:  Miscellaneous

Context: The Ministry of Petroleum and Natural Gas has issued a gazette notification allowing the distribution of Superior Kerosene Oil (SKO) under the Public Distribution System (PDS) across 21 States and UTs, including Delhi and Gujarat.

About Superior Kerosene Oil (SKO):

What it is?

• Superior Kerosene Oil (SKO) is a highly refined middle distillate fraction of crude oil. It is a specific grade of kerosene that has undergone extra processing to remove impurities (like sulphur and aromatics), ensuring it meets stringent quality standards for domestic and industrial use.
• In India, it is primarily distributed through the Public Distribution System (PDS) to provide energy security to low-income households.

Aim: The primary aim of providing SKO is to ensure a reliable and affordable fuel source for cooking and lighting in rural and semi-urban areas.

Key Characteristics of SKO:

• High Smoke Point: It is refined to have a high smoke point (minimum 18-22 mm), which ensures that it burns with a steady, smokeless flame.
• Low Sulphur Content: SKO contains very low levels of sulphur, reducing the emission of harmful oxides (SOx) during combustion, making it safer for indoor use.
• Flash Point: It has a specific flash point (typically above 35°C to 40°C) to ensure safety during storage and transport, preventing accidental ignition.
• Coloration: In India, PDS-destined SKO is often dyed blue to distinguish it from non-subsidized kerosene and to prevent its illegal diversion for adulterating automotive fuels like diesel.

Applications:

• Domestic Cooking: Used in wick stoves and pressure stoves as a primary or backup cooking fuel.
• Lighting: Widely used in hurricane lanterns and simple lamps in areas with unreliable power grids.
• Industrial Use: Used as a solvent in paints, a degreaser in mechanical workshops, and a base for some pesticide formulations.
• Aviation: When further refined and treated with additives, a similar fraction serves as Aviation Turbine Fuel (ATF).

How it differs from Regular Kerosene?

While both are derived from the same petroleum fraction, the Superior tag denotes significant differences:

OPU–IVF–ET Technology

Source:  IE

Subject:  Science and Technology

Context: Scientists at the Indian Veterinary Research Institute (IVRI), Bareilly, have achieved a significant breakthrough by producing five healthy Sahiwal calves from a single donor cow using advanced OPU–IVF–ET technology.

About OPU–IVF–ET Technology:

What it is?

• OPU–IVF–ET stands for Ovum Pick-Up, In Vitro Fertilization, and Embryo Transfer. It is an advanced assisted reproductive technology (ART) for livestock. It involves recovering eggs directly from a donor’s ovaries, fertilizing them in a lab, and then implanting the resulting high-quality embryos into surrogate mothers.

Organization Involved: Indian Veterinary Research Institute (IVRI), Bareilly.

Aim: The technology aims to accelerate genetic improvement of indigenous livestock.

How it Works?

1. Ovum Pick-Up (OPU): Mature eggs (oocytes) are collected from a genetically superior donor cow using ultrasound-guided needles (non-stimulated conditions).
2. In Vitro Fertilization (IVF): The collected eggs are fertilized with high-quality sperm from a proven bull in a strictly controlled laboratory environment.
3. Embryo Culture: The fertilized eggs develop into blastocysts (early-stage embryos) over a few days.
4. Embryo Transfer (ET): These test-tube embryos are then implanted into the uterus of surrogate cows (typically those with lower milk yields).
5. Gestation: The surrogates carry the calves to term (approx. 9 months), resulting in offspring with the superior traits of the original donor.

Key Features:

• High Efficiency: IVRI achieved blastocyst production rates of over 47% in cattle, which is on par with global standards.
• Non-Stimulated Recovery: Scientists can recover eggs without heavy hormone stimulation, ensuring the long-term health of the donor cow.
• Cryopreservation: Embryos can be frozen and stored to be used or transported as needed, allowing for breeding on demand.
• Genetic Multiplication: It allows a single elite cow (e.g., one producing >12 liters/day) to spread its traits to dozens of offspring in a single year.

About Sahiwal Cow:

What it is?

• The Sahiwal is one of the most important indigenous (Zebu) dairy breeds of the Indian subcontinent. It is highly prized for its milk production and hardiness.

Breed & Habitat:

• Origin: Historically from the Montgomery region (now in Pakistan) and the Punjab region of India.
• Prevalence: Primarily found in Punjab, Haryana, and Rajasthan.

Key Characteristics:

• High Milk Yield: It is considered the best indigenous dairy breed, with some cows capable of producing significant lactation yields (up to 3,320 kg).
• Heat Tolerance: Due to its origin in arid regions, it is highly resistant to extreme heat and ticks, making it ideal for tropical climates.
• Physical Traits: Typically reddish-brown or pale red in color. They are characterized by a large hump, a lethargic gait (often called Lola due to their loose skin), and a prominent dewlap.
• Milk Quality: Sahiwal milk is rich in fat and is often associated with the A2 beta-casein protein, which is considered easier to digest and healthier by many consumers.

Jungle Cat

Source:  TH

Subject:  Species in News

Context: A comprehensive new study published in Scientific Reports has established the first national population baseline for the jungle cat (Felis chaus) in India, estimating their numbers between 1.57 lakh and 4.59 lakh

About Jungle Cat:

What it is?

• The jungle cat, also known as the reed cat or swamp cat, is a medium-sized wild cat native to the Middle East, South and Southeast Asia, and southern China. Despite its name, it is not a resident of jungles or dense rainforests, but rather prefers open, well-watered environments.

Habitat:

• Preferred Environment: They avoid dense forests and heavily modified urban landscapes, preferring wetlands, grasslands, and semi-arid regions.
• Agro-pastoral Landscapes: They are frequently found in agricultural fields and farms, where they have adapted to live alongside human activity.
• Geographic Range: In India, major populations are found in Madhya Pradesh, Rajasthan, and Odisha.

IUCN Status:

• IUCN Red List: Least Concern.
• Status in India: Protected under Schedule II of the Wildlife (Protection) Act, 1972.

Key Characteristics:

• Physical Appearance: They have a distinctive white muzzle, yellow irises, and long legs that often feature faint horizontal stripes.
• Large Tufted Ears: Their ears are notably large and end in small black tufts, similar to a lynx, which helps in detecting the subtle movements of prey.
• Nocturnal & Secretive: They are primarily active at night and are notoriously difficult to study due to their shy and elusive nature.
• Diurnal Flexibility: Unlike many other small cats, they are occasionally active during the day to hunt, especially in areas with low human interference.
• Adaptive Hunters: They are strong swimmers and have been known to dive into water to catch fish, though their primary diet consists of small rodents and birds.

Significance:

• By residing in and around farms, jungle cats hunt rodents that destroy crops. This provides a vital ecosystem service to farmers, acting as a biological shield for agriculture.
• Their presence indicates the health of Open Natural Ecosystems (ONEs), which are often overlooked in conservation policies compared to dense forests.

Ghorad (Great Indian Bustard)

Source:  News on Air

Subject:  Species in News

Context: After a decade-long hiatus, a Great Indian Bustard (Ghorad) chick has been born in Gujarat’s Kutch district through a pioneering inter-state conservation effort.

About Ghorad (Great Indian Bustard):

What it is?

• The Great Indian Bustard (Ardeotis nigriceps), locally known as Ghorad in Gujarat and Maharashtra, is one of the heaviest flying birds in the world. It is considered the flagship species of India’s grassland ecosystem and is often called the Guardian of the Grasslands.

IUCN Status: Critically Endangered.

Population: Estimated to be fewer than 150 individuals globally, with the majority residing in Rajasthan’s Desert National Park.

Legal Protection: Listed in Schedule I of the Indian Wildlife (Protection) Act, 1972, providing it the highest level of legal protection.

Habitat:

• Primary Landscape: Dry, open grasslands and scrublands with scattered bushes.
• Geographic Range: Historically found across the Indian subcontinent, it is now restricted to isolated pockets in Rajasthan (Kutch/Thar), Gujarat, Maharashtra, Karnataka, and Andhra Pradesh.
• Nesting: They are ground-nesting birds, making their eggs highly vulnerable to predators like stray dogs and foxes.

Key Characteristics:

• Physical Stature: Large, ostrich-like appearance with a black cap contrasting with a pale neck and brownish body.
• Heavyweight Flyer: Adult males can weigh up to 15 kg and stand about one meter tall.
• Breeding Behavior: During the breeding season, males produce a deep resonant boom that can be heard from nearly a kilometer away to attract females.
• Slow Breeders: Females typically lay only one egg per year, which contributes to their extremely slow population recovery.
• Omnivorous Diet: They feed on a variety of insects (like grasshoppers and beetles), small rodents, reptiles, and seeds, making them natural pest controllers for nearby farms.

About Operation Egg Transfer:

What it is?

• Operation Egg Transfer is a high-tech foster-parenting conservation strategy. It involves replacing an unfertilized egg in a wild nest with a laboratory-fertilized egg to ensure a successful birth in regions where the natural male population has vanished.

Organization Involved: Forest Departments of Gujarat and Rajasthan.

Technical Partner: Wildlife Institute of India (WII).

Aim: The primary aim was to revive the GIB population in Kutch, Gujarat, where the lack of male bustards meant that local females were laying unfertilized eggs.

Key Features:

• Cold Chain/Incubation Logistics: The fertilized egg was transported over 19 hours from Rajasthan to Kutch in a specialized portable incubator to maintain precise temperature and humidity.
• Decoy Strategy: The forest team carefully swapped an unfertilized egg in a wild nest in Abdasa with the fertilized one while the female was away.

The Baltic Sea

Source:  NDTV

Subject:  Mapping

Context: A multinational research expedition aboard the vessel Alkor has set sail from Kiel to map 1.6 million tonnes of rusting World War II munitions and shipwrecks on the Baltic Sea floor.

About The Baltic Sea:

What it is?

• The Baltic Sea is a semi-enclosed, brackish inland sea located in Northern Europe. It is one of the world’s largest bodies of brackish water (a mix of fresh and salt water) and serves as a critical maritime corridor for trade, energy, and telecommunications.

Location & Bordering Nations: The sea is positioned between the Scandinavian Peninsula, the mainland of Northern and Central Europe, and the Danish islands.

• It is bordered by nine countries: Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, and Sweden.
• It is connected to the Atlantic Ocean via the North Sea through the narrow straits of Kattegat and Skagerrak.

Key Characteristics:

• Shallow and Semi-Enclosed: The Baltic Sea is relatively shallow, with an average depth of about 55 m, and its narrow connection with the North Sea causes very slow water circulation, leading to nearly 30 years for complete water renewal.
• Brackish Nature: The mixing of freshwater from 200+ rivers and limited saline inflow from the North Sea creates brackish water, resulting in vertical salinity layering and a highly stratified marine ecosystem.
• Low Biodiversity, High Sensitivity: Because of its young geological formation and unstable salinity conditions, only limited species survive here, making the ecosystem highly fragile and easily disturbed by pollutants or invasive organisms.
• Anthropogenic Pressure: Heavy shipping traffic and dense underwater infrastructure such as Nord Stream pipelines, telecom cables, and offshore wind farms increase ecological stress and accident risks in the Baltic region.

Implications:

• Corroding wartime ammunition releases toxic chemicals such as TNT and mercury, which enter marine food chains and accumulate in fish and shellfish, posing risks to marine life and human consumption.
• Sunken vessels like the Franken wreck still contain large volumes of oil, and any structural collapse may cause severe spills whose impact may persist for decades due to slow water exchange.
