About POCSO Act
- First comprehensive law in India dealing specifically with sexual abuse of children enacted 2012.
- Administered by Ministry of Women and Child Development ensuring child protection and safety nationwide.
- Intended to protect children from sexual assault, sexual harassment, pornographic violations; establish Special Courts for trials.
- 2019 amendment: strengthened penalties for specified offences to deter abusers and promote dignified upbringing for children.
Key Provisions
- Gender-Neutral Legislation
- Act defines child as “any person” under age of 18 ensuring protection regardless of gender comprehensively.
- Mandatory Reporting
- Non-reporting is crime: any person in charge of institution (excluding children) failing to report sexual offence faces punishment.
- No time limit for reporting: victim may report offence at any time, even years after abuse occurred ensuring justice accessibility.
- Victim Protection
- Keeping victim’s identity confidential: Act forbids disclosure of victim’s identity in any media unless authorized by special courts.
Concerns
- Rising Abuse
- Abuse on rise: particularly since Covid-19 outbreak when new forms of cybercrime emerged targeting children online.
- Awareness Gap
- Lack of awareness/knowledge on part of minor girls, boys, parents, society as whole hindering effective protection.
- Criminalisation of Adolescent Sex
- CJI D Y Chandrachud asked lawmakers to address growing concern over criminalisation under POCSO of adolescents engaging in consensual sexual activity.
- Minors aged 16-18 engaging in consensual act under law’s sexual activity definition risk being booked under POCSO.

- Study found: one in four POCSO cases in West Bengal, Assam, Maharashtra were “romantic cases” with victim in consensual relationship with accused.
Law Commission Recommendations
- 22nd Law Commission: lowering age of consent may be counterproductive for women requiring careful consideration.
- Likely to recommend awareness measures on adolescent healthcare including making sex education mandatory in schools.
- Teaching basics of consent under POCSO Act in schools ensuring informed understanding among adolescents.

SWIFT System

About SWIFT
- The SWIFT system is a member-owned cooperative that enables secure financial messaging between institutions.
- Established in 1973 by 239 banks from 15 countries to streamline international financial communication.
- SWIFT facilitates the exchange of secure instructions for cross-border fund transfers between banks.
- It is the largest global network for international payments and settlements.
How SWIFT Works
- Each financial institution receives a unique Bank Identifier Code (BIC) consisting of 8 or 11 characters.
- These codes standardise communication and ensure accurate routing of international payment instructions.
- SWIFT does not transfer or hold money; it only transmits essential financial messages like account details and transfer amounts.
- By standardising protocols, it improves efficiency, predictability, and security in global banking operations.
Governance and Structure
- Headquartered in La Hulpe, Belgium, SWIFT is overseen by central banks of the G10 countries, along with the European Central Bank and the National Bank of Belgium.
- It has approximately 3,500 shareholder institutions, representing global financial networks.
- A 25-member board of directors, elected by these shareholders, governs SWIFT and supervises system management.
Importance in Global Finance
- SWIFT is essential for the functioning of the international financial system due to its secure communication architecture.
- It enables reliable cross-border transactions by reducing operational risks and process inefficiencies.
- Membership ensures seamless access to global financial markets and smooth settlement operations.
Exclusion as a Sanction Tool
- Removal from SWIFT is a powerful economic sanction, restricting a country’s ability to conduct international financial transactions.
- Such exclusion significantly disrupts trade, foreign investment, and global banking access for targeted nations.

Key Features
- Accelerates combustion but does not burn on its own.
- Highly soluble and hygroscopic, absorbing moisture rapidly.
- Thermally unstable, decomposing violently under heat or confinement.
- Appears similar to common salts, making bulk identification difficult.
Regulation in India
- Classified as an explosive under the Explosives Act, 1884, following a 2011 notification.
- Governed by the Ammonium Nitrate Rules, 2012 for manufacture, transport, storage, and import/export.
- Mixtures containing over 45% ammonium nitrate are treated as explosives.
- Requires licences under the IDR Act, 1951 and AN Rules, 2012 for handling and commercial use.
Applications
- Agriculture
- Used as a high-nitrogen NPK 34-0-0 fertilizer.
- Provides efficient nitrogen release and is preferred in some crops over urea.
- Industrial Explosives
- Key ingredient in ANFO (Ammonium Nitrate Fuel Oil), which forms nearly 80% of explosives in mining and quarrying.
- Also used in mixtures like Amatol, Ammonal, Minol, and Nitrolite.
- Terrorism
- Frequently misused in Improvised Explosive Devices (IEDs) due to easy availability and high blast potential.
- Niche Uses
- Used in instant cold packs due to its endothermic dissolution.
- Applied experimentally in off-grid cooling systems and was formerly used in certain airbag systems.
