1.Law Governing Sentence Suspension (Judiciary Powers)

The HinduSuspension of Sentence · Supreme Court · Life Imprisonment

What & Where

Suspension of sentence = temporary halt of punishment during appeal; conviction stands till reversed.

Statutory anchor: Sec 389 CrPC 1973 → Sec 430 Bharatiya Nagarik Suraksha Sanhita 2023.

Ordered by appellate courts (Sessions, High Court, Supreme Court) after trial‐court conviction.

Quick Facts for MCQs

Legal & Policy

Supreme Court stay on Delhi HC order in Unnao case revived scrutiny of suspension doctrine.
BNSS retains CrPC framework; no separate victim-centric safeguards added.
Special laws (POCSO, PMLA) can restrict CrPC suspension via non-obstante clauses.

Judicial Standards

Short fixed terms: suspension routine to avoid appeal right becoming illusory.
Life/sexual offences: court needs ‘palpable error’ showing probable acquittal.
Long incarceration alone ruled insufficient in Shivani Tyagi 2024.

Challenges & Reforms

Dilution of deterrence, witness intimidation, public cynicism in high-profile cases.
Absence of uniform yardsticks breeds forum shopping, inconsistent outcomes.
Suggested: SC-framed guidelines, fast-track appeals, POCSO amendment to cover elected officials.

Key Data Points

Feature	Data-Point
Nature	Discretionary, not a right
Applies to	All punishments incl. life terms & death
Key prerequisite	Appeal or revision filed
Legal effect	Stays execution of sentence only
Victim hearing	Proviso to Sec 389(1) mandates notice to prosecution/victim

4.Secondary Air Pollutants Formation (Air Pollution)

Indian ExpressSecondary Pollutants · PM2.5 · Ozone

Illustration for Secondary Air Pollutants Formation (Air Pollution)

What & Where

Secondary pollutants = atmospheric products of precursor gases; key types include secondary PM2.5, ozone, acids, PANs

CREA finds they form ≈33 % of Delhi’s annual PM2.5 burden, rising during stagnant winter episodes

Particles can form within hours, travel hundreds of km, making Delhi reliant on up-wind emission control

Quick Facts for MCQs

Formation Chemistry

Oxidation; SO₂ → sulfate; sulfate + NH₃ → ammonium sulfate aerosols
Oxidation; NOx → nitric acid; acid + NH₃ → ammonium nitrate particles
Photochemistry; NOx + VOCs + sunlight → ozone, PANs

Winter Smog Dynamics

Stagnant moist winter air accelerates secondary particle surge despite local emission restrictions
Fog droplets provide aqueous medium enhancing sulfate and nitrate generation
Weak winds hinder dispersion, prolonging high-PM events over NCR

Health & Policy

Health; fine secondary PM2.5 reaches alveoli, raising respiratory and cardiovascular risk
Policy; controlling only visible PM10 overlooks crucial SO₂, NOx, NH₃ mitigation
Regional; emissions from coal-rich up-wind states significantly influence Delhi air quality

High-MSP rice and free electricity incentivise relentless groundwater pumping, stalling crop diversification.
Green-Revolution food-security legacy sustains rice-wheat dominance despite semi-arid conditions.
Weak groundwater laws permit unlimited borewell drilling, worsening aquifer stress.

Environmental Impact

Rapid aquifer decline degrades wetlands, soil moisture and biodiversity across Punjab-Haryana plains.
Energy-intensive deeper pumping escalates farm costs and carbon footprint.
Exporting 24 bcm water yearly shifts scarcity burden to future generations.

Policy Initiatives
