1.Aggravating vs Mitigating Factors in Death Penalty (Death Penalty)

Indian Express

What & Where

Death penalty: irreversible state execution for specified grave crimes under Bharatiya Nyay Sanhita 2023, UAPA 1967, NDPS 1985.

Doctrine: “Rarest of rare” (SC, Bachan Singh 1980) decides sentence after weighing aggravating vs mitigating factors in separate post-conviction hearing.

Geography: Retained by 55 nations, abolished by 112 (2022); India among retentionist democracies.

Quick Facts for MCQs

Sentencing Factors

  • Age <30, mental disturbance, reform probability regularly cited as mitigation; inconsistency noted by 262nd Report.
  • Aggravation includes pre-planning, extreme brutality, killing on-duty public servant.
  • Santosh Bariyar 2009: Court must show evidence why reform impossible.

Judiciary Rulings

  • Jagmohan 1972, Bachan Singh 1980 uphold penalty; Machhi Singh 1983 shifts focus to crime’s shock value.
  • Shatrughan Chauhan 2014 protects against execution delay; Dattaraya 2020 quashes death for lack of separate hearing.
  • Suo Motu 2022 referred “meaningful opportunity” issue to Constitution Bench.

Law Commission Reports

  • 35th Report 1967 strongly supported death penalty.
  • 187th Report 2003 flagged procedural flaws without seeking abolition.
  • 262nd Report 2015 urged removal for all offences except terrorism/war.

International Examples

  • 2022: Kazakhstan, PNG, Sierra Leone, CAR abolished; Equatorial Guinea, Zambia limited scope.
  • Only advanced democracies still executing: USA, Japan.
  • Global abolition trend: 48 countries (1991) → 112 (2022).

5.CBDT Principal Purpose Test Guidelines (Double Tax Avoidance)

The Hindu

What & Where

Principal Purpose Test (PPT): DTAA anti-abuse rule denying treaty benefit when dominant intent is tax-saving

CBDT 25 Jan 2025 circular: operationalises PPT prospectively across India’s network of 94 DTAAs

Grandfathering carve-out: legacy routes via Mauritius, Singapore, Cyprus kept outside PPT for pre-specified investment periods

Quick Facts for MCQs

Legal & Policy

  • Applicability limited; no retrospective investigation of pre-2017 inflows
  • Tax officers instructed to consult OECD Commentary, BEPS Action 6, UN Model before invoking PPT
  • Denial consequence: income taxed under domestic law without treaty concessions

International Frameworks

  • BEPS Inclusive Framework unites 147 jurisdictions, India signatory since 2016
  • Pillar 1 reallocates profits to market jurisdictions, separate from PPT but complementary
  • UN Model guides developing nations on balancing source-residence taxing rights

Bilateral Nuances

  • Mauritius, Singapore protocols already embed Limitation-of-Benefits clauses, hence separate grandfathering
  • Cyprus treaty amended 2016; capital-gains benefit on shares bought before 1 Apr 2017 retained
  • Future investments through these centres subject to India’s GAAR even if PPT exempt

Economic Angle

  • NRIs & MNEs must reassess holding structures; routing solely for 0% capital-gains now risky
  • Clearer rules expected to bolster genuine FDI while reducing round-tripping incentives

6.Revised Open Market Sale Scheme Policy (Food Grain Buffer)

PIB

What & Where

OMSS(D): periodic e-auction of surplus wheat & rice from FCI’s central pool to stabilize prices

Nationwide coverage: FCI depots, states may lift grain sans auction over NFSA quota

2024-25 tweak: rice reserve price cut ₹550 to ₹2,250/q to aid ethanol, contain inflation

Quick Facts for MCQs

Scheme Mechanics

  • Inflation control: calibrated releases prevent market spikes, complement MSP procurement
  • Ethanol push: cheaper rice encourages grain-based biofuel distilleries under blending target
  • Safety-net: surplus offload frees storage for fresh MSP buys, averts holding costs

Auction Parameters

  • E-auction platform: weekly bids, all-India depots listed digitally
  • Quantity caps: discourages hoarding, widens trader participation
  • Reserve price setting: ministry revises based on procurement cost, economic cost, market trend

FCI Reforms

  • Digital procurement: nationwide computerisation ensures one-nation one-MSP DBT to farmers
  • Tech adoption: AI grain analysers, digital quality labs feed real-time dashboards
  • Loss minimisation: silo storage, integrated supply chain via ANNA DARPAN portal cut wastage

Food Security Angle

  • NFSA linkage: OMSS releases never compromise TPDS & welfare scheme allocations
  • Fortified rice: parallel rollout through PDS tackles hidden hunger
  • Decentralised procurement: more states under DCP, reducing transport cost, boosting local stocks

Indian Express

What & Where

ADHD: neurodevelopmental disorder marked by inattention, hyperactivity, impulsivity.

Persistence: often begins in childhood, continues into adulthood (3-4 % of adults worldwide).

Study locus: recent life-expectancy analysis from UK, published in British Journal of Psychiatry.

Quick Facts for MCQs

Medical Profile

  • Inattention includes distractibility, forgetfulness, careless mistakes impacting daily tasks.
  • Hyperactivity manifests as restlessness, excessive movement in quiet contexts.
  • Impulsivity leads to interrupting, acting without foresight, risky behaviours.

Risk Factors

  • Genetics: family history sharply elevates susceptibility.
  • Prenatal exposure: nicotine, alcohol, drugs disrupt foetal neurodevelopment.
  • Environment: lead toxicity, low birth weight correlate with higher ADHD incidence.

Management & Therapy

  • Medication: stimulants first-line; non-stimulants used when stimulants contraindicated.
  • Behavioural interventions: structured routines, time-management, reinforcement techniques.
  • Lifestyle tweaks: balanced diet, regular exercise, adequate sleep enhance focus & mood.

Study Findings

  • UK study reports significantly reduced life expectancy for adults with ADHD.
