Context: In a landmark judgment delivered on October 31, 2025, the Supreme Court of India emphatically ruled that investigating agencies cannot directly summon a lawyer representing a client to disclose case-related details. The Court anchored its decision on Section 132 of the Bharatiya Sakshya Adhiniyam (BSA), 2023, asserting that legal communications are protected by privilege unless they fall under clearly defined exceptions.

This article explains the judgment, the law, the constitutional framework, global comparisons, and its significance for India’s legal system — tailored for UPSC aspirants.

Background of the Case

• The case originated from a suo motu writ petition, following a Special Leave Petition by a Gujarat-based advocate who had secured bail for a client.
• The police later summoned him under Section 179 of the BNSS to “elicit details” about the case.
• The High Court upheld the summon. The Supreme Court took exception, terming such summons a serious threat to legal independence.

What Does Section 132 of BSA Say?

Under Section 132 of the Bharatiya Sakshya Adhiniyam, 2023:

“No advocate shall be compelled to disclose any communication made to him in the course of his employment as an advocate by or on behalf of his client…”

This privilege:

• Belongs to the client.
• Is invoked by the advocate.
• Is rooted in the principle of non-self-incrimination under Article 20(3) of the Constitution.

Key Directions of the Supreme Court

1. General Bar on Summons: An investigating officer cannot summon an advocate merely for appearing or advising a client.
2. Exceptions Allowed with Safeguards:
   • Summons must cite facts showing the communication furthered a crime or fraud.
   • It must have written approval from a superior officer (SP rank or higher).
3. Judicial Oversight: Any such summons is reviewable under Section 528 of the BNSS.
4. In-house Counsel Not Protected: Full-time salaried legal employees cannot claim Section 132 privilege.
5. Digital Devices and Documents: Must be opened only in court, with technical assistance for confidentiality.

Constitutional and Statutory Foundations

Why the Ruling Matters

• Strengthens rule of law: Lawyers can’t be bullied to weaken an accused’s defense.
• Promotes fairness: Upholds adversarial legal system’s neutrality.
• Clarifies limits of state power: Prevents misuse of criminal procedure to intimidate legal professionals.

Distinction from Past Cases

The Court declined to frame new guidelines (as in Vishaka v. State of Rajasthan) noting:

• No legislative vacuum exists.
• The BSA’s provisions and exceptions are comprehensive.
• Precedents like Jacob Mathew (on medical negligence) are not comparable.

In-House Counsel: Why They’re Not Covered

Based on Bar Council Rule 49:

• Salaried employees cannot be practicing advocates.
• SC cited the European Court of Justice’s Akzo Nobel case:
  • In-house lawyers lack independence due to employer control.
  • Hence, they are not entitled to privilege.

Global Legal Comparisons

Critical Evaluation

Positives:

• Curtails overreach by investigative agencies.
• Gives clear enforcement structure for lawyer protections.
• Preserves faith in legal institutions.

Cautions:

• Cannot shield lawyers engaged in criminal conspiracy.
• Over-broad reading of privilege may stall justice in genuine misuse.

Way Forward

1. Capacity-building of law enforcement on legal boundaries.
2. Codified SOPs for exceptions under Section 132 BSA.
3. Protection for digital-age confidentiality (e.g. end-to-end encryption).
4. Clarity on In-House Legal Ethics to prevent misuse while respecting corporate independence.

Conclusion

The 2025 Supreme Court ruling anchored in Section 132 BSA is a milestone in India’s constitutional jurisprudence. It reaffirms that legal advice is sacrosanct, and coercing lawyers into becoming agents of the state threatens the very edifice of justice and democracy.

For UPSC aspirants, this case offers insights into how constitutional rights, statutory frameworks, and judicial innovation intersect to safeguard fundamental freedoms.

Solid-State Batteries: The Next Generation of Energy Storage

Solid-state batteries (SSBs) are a revolutionary type of battery technology that uses a solid electrolyte instead of the liquid or gel polymer electrolytes found in conventional lithium-ion batteries. This fundamental change in composition promises significant improvements in safety, energy density, and performance.

• Imagine a traditional lithium-ion battery like a sandwich where the bread slices are the electrodes (anode and cathode), and the filling is a wet, liquid electrolyte. This liquid electrolyte allows lithium ions to move back and forth between the electrodes, charging and discharging the battery.
• Now, imagine a solid-state battery as a similar sandwich, but instead of a wet filling, it has a thin, solid slice of cheese or a ceramic wafer as its electrolyte. This solid material still allows the lithium ions to pass through, but without the fire risk, leakage issues, or degradation problems associated with liquids.

Example: Toyota has been a pioneer in solid-state battery research, developing prototypes that use a sulfide-based solid electrolyte. Another example is QuantumScape, which uses a proprietary ceramic solid electrolyte, targeting high-energy density and fast-charging capabilities for electric vehicles

Features of Solid-State Batteries:

1. Enhanced Safety:
   • No Flammable Liquid Electrolyte: This is the most significant advantage. Liquid electrolytes are highly flammable and can catch fire or explode if the battery is overcharged, short-circuited, or physically damaged (thermal runaway). Solid electrolytes eliminate this risk
   • No Leakage: Solid components mean no risk of electrolyte leakage, which can damage devices and pose health hazards.
2. Higher Energy Density:
   • Lithium Metal Anode: Solid electrolytes are compatible with a lithium metal anode, which has a much higher theoretical energy density compared to the graphite anodes used in current Li-ion batteries. This means more power in a smaller and lighter package.
   • Compact Design: The solid nature allows for more compact stacking of cells without the need for bulky separators or cooling systems required for liquid electrolytes
3. Longer Cycle Life:
   • Reduced Degradation: The solid electrolyte is more stable and less prone to side reactions with the electrodes that typically degrade liquid electrolytes over time, leading to a longer battery lifespan
   • Less Dendrite Formation: While still a challenge, some solid electrolytes are better at suppressing the formation of lithium dendrites (needle-like structures that can cause short circuits) during charging, further improving safety and longevity
4. Wider Operating Temperature Range and Stability: Solid materials are generally more stable across a broader range of temperatures, potentially allowing SSBs to operate more efficiently in extreme hot or cold conditions compared to liquid electrolyte batteries, which can become sluggish or unstable
5. Faster Charging (Potential) and High Ionic Conductivity: Advanced solid electrolytes are being developed with high ionic conductivity, which can enable faster charging rates without compromising safety or battery life.

Context: The efficacy of the self-enumeration module for the first phase of Population Census 2027 will be tested from Saturday (November 1, 2025) with enumerators visiting the homes of prominent citizens in their areas and helping them fill the details on a website, a senior government official told The Hindu. This will be the first digital Census, and the first to enumerate caste in independent India.

What Is a Census?

A census is the official enumeration of the population, conducted periodically by the government. It provides critical data on the size, composition, socio-economic features, and geographical distribution of the population.

• India’s first Census was held in 1881 under British rule.
• Since then, it has been conducted every 10 years.
• The exercise includes demographic, cultural, and economic information of the entire population.

Why Is the Census Important?

Evidence-Based Policy Making: Census data provides a solid foundation for planning public health, education, housing, and employment schemes.

Electoral and Political Utility: Census data supports delimitation of parliamentary and assembly constituencies, and helps implement reservation policies (e.g., one-third women’s reservation).

Welfare Delivery and Budget Allocation: Data disaggregation helps ensure targeted benefits to SCs, STs, OBCs, minorities, senior citizens, and other vulnerable groups.

Demographic and Social Analysis: It captures fertility, mortality, migration, urbanization, ageing, and literacy patterns, critical to understanding human development.

Benchmark for Surveys: Surveys like NFHS, NSSO, etc., use census data as a benchmark for extrapolating trends. Without the census, these surveys lack accuracy.

Legal Provisions for Census in India

Timeline and Status of India’s Upcoming Census

• Census 2021 postponed due to COVID-19.
• Next Census will be conducted in two phases:
  • Oct 2026: For snow-bound regions (e.g., J&K, Himachal, Ladakh).
  • March 2027: For rest of India.
• Data Release expected by end of 2027.

What Is the National Population Register (NPR)?

The NPR is a register of all “usual residents” (living in a locality for 6+ months) of India, created under the Citizenship Act, 1955.

• Managed by the Registrar General of India.
• Includes foreigners.
• Data from NPR feeds into National Register of Indian Citizens (NRIC/NRC).

Census and Caste Enumeration

• The upcoming census will include caste and sub-caste data for the first time post-Independence.
• Past censuses recorded only SC/ST data.
• This enables:
  • Better welfare budgeting.
  • Assessment of access to schemes like PMAY, Skill India.
  • Improved social justice indicators.

Innovations in the 2026–27 Census

• Digital data collection through mobile apps (in 16 languages).
• Self-enumeration option for citizens.
• Census Management & Monitoring System (CMMS) portal for real-time coordination.
• Faster compilation and analysis with GIS mapping and real-time dashboards.

Determinants of Population Change

Example:

• India’s IMR declined from 37/1000 (2015) to 30/1000 (2019).
• MMR improved from 8.1 (2015–17) to 7.3 (2016–18).

WHO Oral Rehydration Salts (ORS) Formulation

The World Health Organization (WHO) and UNICEF currently recommend a Low-Osmolarity ORS formulation for the prevention and treatment of dehydration due to diarrhea. This precise composition is essential for effective fluid and electrolyte absorption in the intestine.

The composition per 1 Litre of clean drinking water is as follows:

Key Role of Formulation: The $1:1$ molar ratio of glucose to sodium is crucial for activating the sodium-glucose co-transport mechanism in the small intestine, which facilitates the absorption of water into the body. High-sugar, non-compliant drinks can worsen diarrhea by drawing water into the intestines.

Component	Chemical Name	Concentration (g/L)	Concentration (mmol/L)
Glucose, Anhydrous (Sugar)	C6H12O6	13.5g/L	75 mmol/L
Sodium Chloride (Salt)	NaCl	2.6g/L	75 mmol/L
Potassium Chloride	KCl	1.5g/L	20 mmol/L
Trisodium Citrate, Dihydrate	C6H5Na3O.2H2O	2.9 g/L	10 mmol/L (Citrate)
Total Osmolarity			245 mOsm/L

Delhi High Court’s Stand on ORS-Labelled Beverages

• Upholding the FSSAI Ban: The Delhi High Court made it clear that it would not interfere with the FSSAI’s order (dated October 30) banning the sale of beverages labelled with the term ‘ORS’.
• Public Health is Paramount: The court firmly stated that “Public health considerations are paramount” and must take precedence over commercial interests.
• Product Flagged as Health Hazard: Justice Sachin Datta noted that the FSSAI had flagged such non-compliant ORS-labelled products as a “health hazard” and “hazardous,” making an interim arrangement impossible.
• Refusal to Exhaust Existing Stock: The court refused the plea by Dr. Reddy’s Laboratory (DRL) to permit the sale and exhaustion of its existing stock of the ‘Rebalanz VITORS’ product.
• Pathway for Rebranding: The court orally proposed that DRL could approach the FSSAI for guidance on its existing stock and indicated it will allow DRL to rebrand its product (e.g., to ‘Rebalanz Vitenergy’) before continuing to sell it.
• No Possibility of Interim Relief: The court clearly indicated that it would pass orders that would allow the FSSAI’s embargo to continue, stating, “I’m not disturbing it given the public health concerns.”

FSSAI Order:

• Violation and Misleading Practice: The FSSAI orders (October 14 and 15) reasoned that using the term ‘ORS’ in trademarks or names for food products (like fruit-based, ready-to-drink beverages)—even with prefixes or suffixes—violates the Food Safety and Standards Act, 2006, by being “false, deceptive, ambiguous, and erroneous.”
  • ORS (WHO formula) is classified as a drug and is regulated under the Drugs and Cosmetics Act, 1940. Most high-sugar electrolyte drinks are classified as food and are regulated by FSSAI.
  • Food Business Operators (FBOs) were directed to immediately remove the word ‘ORS’ from all product packaging, advertisements, and brand names.
  • Non-compliance is punishable as misbranding and misleading consumers under the Food Safety and Standards Act, 2006.
• Risk of High-Sugar Drinks: The FSSAI’s October 30 order specifically highlighted that the ingestion of high-sugar electrolyte drinks marketed as ORS can “worsen dehydration” by drawing water out of body cells, posing a “direct and immediate risk to human health.”

Note: This FSSAI directive withdrew previous FSSAI orders (from 2022 and 2024) that had temporarily permitted the use of ‘ORS’ in brand names provided they carried a mandatory disclaimer stating: “The product is NOT an ORS formula as recommended by WHO.”The new rule enforces a complete ban on the non-compliant use of the term.
