Anti-Defection Law Merger Provision: Tenth Schedule Rules, Two-Thirds Majority & UPSC Notes

June 15, 2026

Source: The Hindu | Page 13 | Tags: 15 June 2026, Anti-Defection Law, GS2, Political Parties, Polity

Context:
A group of around 20 Trinamool Congress MPs has informed the Lok Sabha Speaker of its decision to merge with the National Citizens Party of India. The group claims support of more than two-thirds of TMC MPs and seeks protection under the merger provision of the Anti-Defection Law.

Anti-Defection Law

Constitutional Basis

Tenth Schedule

Added By

52nd Constitutional Amendment Act, 1985

Split vs Merger

Split

Earlier, a split by one-third members was exempt from disqualification.

This exception was removed by the 91st Constitutional Amendment Act, 2003.

Merger

Merger remains valid if at least two-thirds of legislators agree to join another political party.

In such cases, members are protected from disqualification.

Why Merge with NCPI?

Since the split exception no longer exists, merely forming a separate faction can attract disqualification.

Therefore, the MPs have chosen to merge with a registered political party and claim protection under the merger clause.

This is being seen as the first legal step before seeking recognition of their faction in Parliament.

Why Was This Not Seen in Shiv Sena / NCP Cases?

In those cases, the dispute was mainly over which faction represented the original party and controlled its name and symbol.

Here, the MPs are first relying on the merger provision of the Tenth Schedule through another registered party.

Registered vs Recognised Party

Registered Party

Registered with Election Commission of India under Section 29A of the Representation of the People Act, 1951.

Recognised Party

A registered party that fulfils ECI criteria for State Party or National Party status.
Gets a reserved symbol.

Key Difference

Every recognised party is registered, but every registered party is not recognised.

PYQ Fact

The term “political party” appears in the Constitution through the Tenth Schedule.

Drought and Antimicrobial Resistance: Climate Change Impact on Soil Bacteria Explained

June 15, 2026

Source: The Hindu | Page 11 | Tags: 15 June 2026, Antimicrobial Resistance (AMR), Environment, GS3, Health

Context:
A Nature Microbiology study says drought stress can increase antimicrobial resistance in soil bacteria by concentrating natural antibiotics in dry soil, favouring resistant bacteria.

This may worsen AMR by 2050, especially in drought-prone regions like India.

Antimicrobial Resistance

Antimicrobial Resistance occurs when microbes stop responding to medicines, making infections difficult to treat.

It can occur in:

Bacteria
Viruses
Fungi
Parasites

Major Drivers of AMR

Wrong or incomplete antibiotic doses
Overuse of antibiotics in humans
Antibiotic use in livestock farming
Wastewater pollution
Pharmaceutical pollution

Key Finding of the Study

When soil dries due to drought, natural antibiotics become concentrated.

This creates survival pressure where resistant bacteria survive better.

This shows that climate change can directly influence AMR, not just medical misuse.

India’s Vulnerability

India is vulnerable due to:

Frequent droughts
High antibiotic use
Livestock farming
Wastewater irrigation
Weak rural healthcare access

Why This Matters

Links climate change with public health.
Shows that AMR is not only a hospital or medicine-use problem.
Drought-prone regions may face higher AMR risk.
Requires One Health approach linking humans, animals and environment.

Assam Nagaland Oil and Gas MoU: Hydrocarbon Exploration, Energy Security & PNGRB Facts

June 15, 2026

Source: The Hindu | Page 11 | Tags: 15 June 2026, Energy Security, GS3, Petroleum & Natural Gas

Context:
The Centre, Assam and Nagaland have signed an MoU to resume oil and gas exploration in the Disputed Area Belt along the Assam–Nagaland border after nearly 30 years.

The agreement aims to unlock hydrocarbon resources, increase domestic production and strengthen India’s energy security.

Northeast Hydrocarbon Potential

Assam is the birthplace of India’s oil industry.
Digboi is one of India’s earliest oil centres.
Assam accounts for nearly 22% of India’s crude oil reserves.
Assam accounts for around 15% of India’s natural gas reserves.

Major Oil and Gas Fields

Digboi
Naharkatiya
Moran
Lakwa
Rudrasagar

Nagaland’s Potential

Nagaland has significant untapped hydrocarbon potential in the Naga Schuppen Belt of the Assam–Arakan Basin.

MoU Coverage

The MoU covers a resource-rich belt of over 1,000 sq km along the inter-state border.

Upstream and Downstream

Upstream

Exploration
Drilling
Production of crude oil and natural gas

Downstream

Refining
Processing
Storage
Transportation
Distribution
Marketing of petroleum products and natural gas

Petroleum and Natural Gas Regulatory Board

Status

Statutory body under the PNGRB Act, 2006

Functions

PNGRB regulates downstream activities only, such as:

Pipelines
City Gas Distribution
Transportation
Marketing

Important Limitation

PNGRB does not regulate upstream activities such as exploration and production.

PYQ Fact

Exploration and production of crude oil / natural gas fall outside PNGRB’s jurisdiction.

Transportation, distribution and marketing fall within PNGRB’s jurisdiction.

Higher Ethanol Blending in India: Beyond E20, Flex-Fuel Vehicles & Energy Security

June 15, 2026

Source: The Indian Express | Explained Page | Tags: 15 June 2026, Alternative Fuel Technologies, Biofuels, Energy Security, GS3

Context: Higher Ethanol Blending in India
After achieving the 20% ethanol blending target, E20, ahead of schedule, India is preparing for higher ethanol blends such as E25, E30 and E85, along with adoption of flex-fuel vehicles to reduce crude oil imports and strengthen energy security.

Alternative Powertrain Vehicles

Alternative Powertrain Vehicles use fuels or propulsion systems other than conventional petrol or diesel engines.

Important Types

Battery Electric Vehicle
Hydrogen Fuel Cell Vehicle
Fuel Cell-Electric Hybrid Vehicle
Flex-Fuel Vehicle

Flex-Fuel Vehicle

A Flex-Fuel Vehicle can run on different petrol-ethanol blends.

How It Works

It uses an Engine Control Module, an onboard computer that detects the fuel blend and automatically adjusts engine performance.

Its engine and fuel system components are designed to handle higher ethanol content.

Ethanol Blends

E20

20% Ethanol
80% Petrol
Current national target achieved

E85

85% Ethanol
15% Petrol
Requires flex-fuel vehicles and supporting infrastructure

Why is India Moving Beyond E20?

India imports nearly 85% of its crude oil requirement.
Higher ethanol blending can further reduce import dependence.
Supports domestic biofuel production.
Supports farmer incomes.
Builds a long-term flex-fuel ecosystem.

Long-Term Roadmap

E20
→ Higher Ethanol Blends
→ Flex-Fuel Ecosystem

Brazil’s Experience

Ethanol programme started in the 1970s.
Flex-fuel vehicles dominate the market.
Consumers can choose petrol, ethanol or blends at fuel stations.

India’s Challenges

Most vehicles are currently optimised for E20.
Higher ethanol blends may reduce mileage because ethanol has lower energy content.
Vehicle modification is required.
Fuel infrastructure needs to be upgraded.
Adequate ethanol supply must be ensured.
Food vs fuel concerns may arise if feedstock demand increases.
