Constitutional Limits on Free Speech (Article 19(2))
Only eight specific grounds for restricting free speech:
Sovereignty & integrity of India
Security of the State
Friendly relations with foreign States
Public order
Decency or morality
Contempt of court
Defamation
Incitement to an offence
No additional restrictions are allowed.
Courts must strictly interpret restrictions.
Key Judicial Precedents
Case
Principle Established
Shreya Singhal v. Union of India (2015)
Struck down vague terms like “annoyance” under Section 66A IT Act; reasserted narrow grounds for restricting speech.
Kaushal Kishore v. State of UP (2023)
Confirmed that Article 19(2) is exhaustive – no extra restrictions.
Supreme Court March 2025 Ruling
Speech should be judged by reasonable person standards, not hypersensitive perspectives.
Critical Analysis
Concerns:
Judicial inconsistency: Varying approaches by different benches.
Potential bias in interpreting “harm” and “intent.”
Risk of chilling effect on academic and critical speech.
Defence’s Argument:
Posts were patriotic and not intended to cause harm.
Implication:
This case could reshape the boundaries of free speech in India, especially during national crises.
Summary
The Supreme Court’s handling of the case reflects a nuanced shift in free speech jurisprudence:
Freedom of expression is protected, but courts may scrutinize the intent and impact of speech.
The case highlights tensions between state security concerns and constitutional freedoms.
The evolving interpretation of “reasonable restrictions” could influence future cases, particularly those involving academic freedom and social media speech.

2. Golaknath v. State of Punjab (1967): Landmark Case in Constitutional Law – Polity
Why in News?
Golaknath case (IC Golaknath v. State of Punjab, 1967): A pivotal Supreme Court judgment that restricted Parliament’s power to amend fundamental rights.
First time the Court ruled that Parliament cannot amend fundamental rights, emphasizing the protection of civil liberties.
Background of the Case
Aspect
Details
Case Name
IC Golaknath v. State of Punjab, 1967
Facts
The Golaknath family, landowners from Punjab, challenged the Punjab Security of Land Tenures Act, 1953, which declared their land as “surplus” under land ceiling laws. They argued it violated their Fundamental Rights to property under Articles 19(1)(f) and 31.
Ninth Schedule Issue
The law was placed in the Ninth Schedule (via 17th Constitutional Amendment) to make it immune from judicial review.
Core Legal Question
Can Parliament amend Fundamental Rights under Article 368, or are such amendments invalid under Article 13(2)?
Petitioners’ Argument
Fundamental rights are sacrosanct; Parliament cannot amend them.
Government’s Argument
Parliament has full power to amend the Constitution, including Fundamental Rights.
Supreme Court’s Verdict (27 February 1967)
Aspect
Ruling
Bench Strength
11 Judges
Majority
6:5 in favour of Golaknath
Key Holding
– Parliament cannot amend Fundamental Rights. – Amendments = Law under Article 13(2) and must adhere to Fundamental Rights. – This restriction applies prospectively (doctrine of prospective overruling).
Overruled Cases
– Sankari Prasad v. Union of India (1951) – Sajjan Singh v. State of Rajasthan (1964) (Both had earlier upheld Parliament’s power to amend Fundamental Rights.)
Impact on Ninth Schedule
Laws placed in the Ninth Schedule could still be subject to judicial review if they violated Fundamental Rights.
Key Doctrines Introduced
Doctrine
Meaning
Purpose
Doctrine of Prospective Overruling
The Court’s ruling applies only to future cases, not retroactively.
To avoid legal chaos and maintain stability in past laws.
Fundamental Rights as Inviolable
Fundamental Rights are transcendental and cannot be amended or abrogated by Parliament.
Protects civil liberties from majoritarian laws.
Impact of the Judgment
Positive Impact
Criticisms
– Strengthened the judicial role in safeguarding civil liberties. – Ensured Parliament could not override citizen rights through constitutional amendments.
– Restricted Parliament’s flexibility to implement socio-economic reforms (e.g., land reforms). – Led to a constitutional crisis over the amending power, eventually resolved by Kesavananda Bharati case (1973).
Subsequent Developments
The Kesavananda Bharati case (1973)overturned Golaknath to an extent, ruling that Parliament can amend Fundamental Rights as long as it does not alter the “Basic Structure” of the Constitution.
Golaknath, however, remains a milestone in asserting the importance of Fundamental Rights.
Summary
Golaknath v. State of Punjab (1967) was a turning point in Indian constitutional law.
The Court ruled that Parliament cannot amend Fundamental Rights, marking the first significant limitation on Parliament’s power under Article 368.
Introduced prospective overruling to maintain legal stability.
The decision reinforced the sanctity of Fundamental Rights and the judiciary’s role in their protection.
Set the stage for the later Kesavananda Bharati case (1973) and the Basic Structure doctrine.

5. Short Selling and Associated Risks – Economy
Why in News?
SEBI (Securities and Exchange Board of India) is considering easing restrictions on short selling for most stocks.
Earlier, a January 2024 proposal aimed to ban short selling in stocks outside the Futures & Options (F&O) segment, creating market uncertainty.
The debate highlights the opportunities and risks of short selling in Indian markets.
What is Short Selling?
Aspect
Explanation
Definition
A trading strategy where an investor sells a stock they don’t own, hoping to buy it back later at a lower price and make a profit. Opposite of traditional “buy low, sell high.”
How It Works
1.Borrow stock from a broker → 2. Sell at current market price → 3. Buy it back later (hopefully at a lower price) → 4. Return the stock to the broker.
Example
– Short Sell at ₹100 → Buy back at ₹90 → Profit = ₹10. – Short Sell at ₹100 → Price rises to ₹130 → Loss = ₹30.
Key Point
Profit is limited (since price can only fall to zero), but losses are theoretically unlimited (since prices can rise indefinitely).
Types of Short Selling in India
Type
Key Features
Risk Profile
Spot Market Short Selling
– Intraday only: Must buy back before 3:30 PM (market close). – Short delivery risk if not squared off → penalties.
Moderate Risk: Must close same day.
Futures Market Short Selling
– Can hold positions overnight or longer (until expiry). – Requires higher margin → suited for experienced traders.
Higher Risk: Exposed to overnight market movements.
Risks Associated with Short Selling
Risk
Explanation
Impact
Unlimited Losses
If stock prices rise instead of falling, there is no upper limit to potential losses.
Example: Short at ₹100, price rises to ₹300 → Loss ₹200 per share.
Short Delivery Risk (Spot Market)
Failure to buy back before market close leads to auction penalty (could be 20%+ of value).
Penalty + forced buy at higher prices.
Liquidity Risk
In illiquid stocks, buying back may be difficult → forced to buy at higher prices.
Increases loss potential.
Market Volatility
Heavy short selling can amplify price fluctuations → contributes to market instability.
May trigger regulatory interventions (circuit breakers, bans).
Regulatory Risk
SEBI can impose sudden restrictions or bans on short selling in certain scenarios.
Adds unpredictability for traders.
SEBI’s Regulatory Stance
Aspect
Details
Past Concerns
January 2024 proposal aimed to ban short selling outside the F&O segment.
Current Proposal (2025)
Likely to ease restrictions and allow broader short selling access.
Objective
Strike a balance between market efficiency (short selling provides price discovery, hedging) and risk control (prevent manipulation, excessive volatility).
Benefits of Short Selling (If Regulated Properly)
Benefit
Explanation
Price Discovery
Helps identify overvalued stocks → market becomes more efficient.
Liquidity
Increases market liquidity by enabling two-sided trade.
Hedging Tool
Useful for risk management (e.g., hedging long positions).
Checks Speculation
Allows market participants to express negative views on stocks → prevents irrational exuberance.
Summary
Short selling is a strategy where investors sell borrowed stocks to profit from price drops.
It offers liquidity and price discovery benefits, but carries significant risks:
Unlimited losses if prices rise.
Short delivery penalties in spot markets.
Liquidity challenges in illiquid stocks.
SEBI’s evolving stance reflects a balancing act between market freedom and risk containment.

7. The Maths of How India’s Coastline Lengthened Without Gaining Land – Geography
Why in News?
The Ministry of Home Affairs (2023-24 report) updated India’s coastline length from 7,516.6 km to 11,099 km.
The increase is due to advanced mapping technologies, not actual land gain.
Key Takeaways
Aspect
Details
Previous Measurement
7,516.6 km (based on earlier, lower-resolution maps).
Updated Measurement (2023-24)
11,099 km (based on high-resolution charts).
Reason for Change
Not physical expansion, but finer mapping techniques capturing minute coastal features like estuaries, tidal flats, and inlets.
Impact
Affects maritime security, disaster preparedness, resource management, and policy-making.
How Did the Coastline Get Longer Without Adding Land?
The Coastline Paradox
Proposed by mathematician Lewis Fry Richardson:
The measured length of a coastline increases as measurement scale becomes finer.
Coastlines are fractal in nature—they have irregular shapes (bays, inlets, estuaries).
A rough measurement smooths over small features, while finer measurement captures every detail, making the coastline appear longer.
Example:
Measurement Scale
Coastline Length
Coarse (low-res)
Shorter length, misses small features
Fine (high-res)
Longer length, captures every irregularity
Mapping Techniques That Changed the Numbers
Technology
Function
Electronic Navigation Charts (ENCs)
High-precision digital maps for maritime navigation.
Geographic Information Systems (GIS)
Layered spatial analysis of land-water boundaries.
LiDAR-GPS
Laser-based, high-resolution elevation and terrain mapping.
These tools reveal estuaries, tidal creeks, sandbanks, and inlets that older methods missed.
Broader Implications of Updated Coastline Data
Sector
Impact
Maritime Security
Improved mapping → better surveillance, patrolling, and defense.
Disaster Preparedness
Accurate coastal data crucial for cyclone early warning systems and tsunami modeling.
Resource Management
Better management of fisheries, minerals, and marine biodiversity.
Legal Frameworks
Redefines maritime zones under UNCLOS: Territorial waters, Exclusive Economic Zones (EEZ), and Continental Shelf claims.
– Territorial Sea: 12 nautical miles – Contiguous Zone: 24 nautical miles – EEZ: 200 nautical miles – Continental Shelf: Up to 350 nautical miles (in some cases).
The increase in India’s coastline length is a mathematical and cartographic outcome, not a physical one.
Advanced GIS, LiDAR, and ENC technologies have enabled finer measurement, revealing intricate features of the coastline.
This has implications for security, disaster management, and sustainable coastal development.
A classic example of the Coastline Paradox: The more accurately we measure, the longer the boundary appears.
Exam Connect – Possible Questions
Prelims
The length of a coastline varies depending on: a) The physical expansion of the coastline. b) The resolution of the mapping technique used. c) The political boundaries of the state. d) The age of the coastline. Answer: b) The resolution of the mapping technique used.

8. The Coastline Paradox – Environment
Why in News?
In December 2024, the Ministry of Home Affairs updated India’s coastline length in its 2023–24 report:
From 7,516.6 km → 11,098.8 km.
No territorial expansion or tectonic changes: the change arises from refined measurement techniques, illustrating the Coastline Paradox.
What is the Coastline Paradox?
Aspect
Details
Origin
First identified by Lewis Fry Richardson (British mathematician and physicist) in early 20th century; mathematically explored by Benoit Mandelbrot (1967).
Definition
The measured length of a coastline depends on the scale of measurement. As measurement units get smaller, the measured length increases, revealing more intricate details.
Key Idea
A finite geographical area (like a country’s coastline) can have a theoretically infinite boundary length because coastlines are fractals—infinitely complex shapes with self-similar patterns at different scales.
Analogy
Imagine measuring a jagged cliff using a large stick vs. a small toothpick: the smaller the tool, the more details you capture.
Extreme Example
If you measure India’s coastline using a unit the size of a water molecule, the length could theoretically approach infinity!
Illustration of the Coastline Paradox
