Current Affairs [Prelims] Lexicon – September, 2024

Polity & Governance

12th Schedule

The 12th Schedule, added by the 74th Constitutional Amendment Act of 1992, lists eighteen functions devolved to urban local bodies, including urban planning, water supply, sanitation, and public health. These functions are meant to empower municipalities with administrative and financial autonomy. However, in practice, many of these functions are managed by multiple agencies, causing overlapping authority and reducing the independent power of city governments. The Schedule aims to promote decentralization and improve urban governance by clearly defining municipal responsibilities.

Why in news?

The report on urban governance notes that despite the 12th Schedule, multiple agencies managing devolved functions weaken city governments authority, impacting governance effectiveness.

6th Schedule Areas

The 6th Schedule of the Constitution of India provides autonomous administrative councils to tribal regions in Assam, Meghalaya, Tripura, and Mizoram. These councils have legislative, judicial, and executive powers to govern tribal affairs and protect indigenous cultures. In Assam, the 6th Schedule areas include districts like Karbi Anglong and Dima Hasao. The councils can make laws on land, forest management, and social customs. The autonomy limits the direct application of state laws, including Assam Accord implementations, without local approval. This arrangement preserves tribal identity and self-governance within the Indian federal framework.

Why in news?

The Assam government will implement Clause 6 recommendations statewide except in 6th Schedule areas, where implementation requires concurrence from local authorities and people.

Arbitration Council of India

The Arbitration Council of India (ACI) was established by the 2019 amendment to the Arbitration and Conciliation Act, 1996, to promote arbitration and improve the arbitration ecosystem in India. The ACI is tasked with accrediting arbitrators, maintaining a roster of qualified arbitrators, and developing institutional arbitration facilities. Despite being legislated, the council has not yet been constituted as of 2024. The ACI aims to standardize arbitration practices and enhance the quality of arbitral awards. It is expected to play a key role in reducing arbitration delays and costs once operational. The council is also designed to promote India as a global arbitration hub.

Why in news?

The 2019 amendment created the Arbitration Council of India, but it remains unconstituted as the government reviews arbitration laws to reduce pendency and costs.

Article 163 of the Constitution of India

Article 163 mandates that the Governor of a state acts on the aid and advice of the Council of Ministers, except in situations where the Constitution requires the Governor to act at their discretion. It establishes the Governors role as largely ceremonial but allows discretionary powers in exceptional circumstances. This article is fundamental in defining the balance of power between the Governor and the elected government. The Supreme Court has interpreted it to permit independent action by Governors when there is a real likelihood of bias or conflict of interest in the Councils advice. This provision is often invoked in political and constitutional disputes.

Why in news?

Siddaramaiah challenged the Governors sanction for investigation, citing Article 163, arguing the Governor should have followed the Council of Ministers advice, which was ignored.

Article 172 of the Constitution of India

Article 172 of the Constitution of India prescribes that the term of a state legislative assembly is five years from the date appointed for its first meeting unless dissolved sooner. This article allows the Parliament to extend the term during a national emergency, but such extension must be ratified by the legislatures of at least half of the states. The article ensures a fixed tenure for state governments, maintaining federal balance. It was part of the original constitutional framework adopted in 1950 and has been invoked rarely. Amendments to this article without state ratification challenge the federal structure and are constitutionally contentious.

Why in news?

The High-Level Committees proposal for One Nation, One Election suggests amending Article 172 to synchronize state assembly terms with Lok Sabha elections without requiring state ratification, raising constitutional and federal concerns.

Article 174(2)(b) of the Constitution of India

Article 174(2)(b) empowers the Governor of a state to dissolve the Legislative Assembly “from time to time.” This dissolution can occur on the recommendation of the Council of Ministers, effectively ending the current Assembly’s term prematurely. Once dissolved, the Election Commission of India (ECI) is mandated to conduct fresh elections within six months. This provision allows flexibility in state governance and election timing, enabling early elections if political circumstances demand. It is a critical constitutional mechanism for managing state assemblies and ensuring democratic continuity under exceptional or strategic political situations.

Why in news?

The article discusses the possibility of early Delhi Assembly elections, referencing Article 174(2)(b) as a legal basis for dissolving the Assembly before its term ends.

Article 19(1)(g) of the Constitution of India

Article 19(1)(g) guarantees all citizens the right to practice any profession, or to carry on any occupation, trade, or business. This right is subject to reasonable restrictions under Article 19(6). It has been invoked in cases involving digital intermediaries and content regulation, arguing that excessive government control can infringe on professionals ability to operate freely. The Bombay High Court found that the amended IT Rules violated Article 19(1)(g) by imposing vague and overbroad restrictions, affecting social media intermediaries’ right to conduct business without undue state interference.

Why in news?

Justice Chandurkar ruled that the amended IT Rules infringed upon Article 19(1)(g), affecting the right of intermediaries to conduct their business, contributing to the strike down of the FCU provision.

Article 19(2) of the Constitution of India

Article 19(2) permits the Government of India to impose reasonable restrictions on the freedom of speech and expression for reasons including sovereignty, security, public order, decency, or defamation. These restrictions must be narrowly defined and justified to prevent arbitrary censorship. The Bombay High Court ruled that the amended IT Rules exceeded these limits by allowing vague and broad restrictions on speech without procedural safeguards, violating the constitutional protection of free expression. The article serves as a key legal standard in assessing laws regulating speech and digital content in India.

Why in news?

The Bombay High Court struck down the amended IT Rules for violating Article 19(2) by imposing vague and excessive restrictions on online speech through the FCU mechanism.

Article 20(3) of the Constitution of India

Article 20(3) protects individuals from self-incrimination, ensuring that no person accused of an offense can be compelled to testify against themselves. It guarantees the right to remain silent during investigations and trials, safeguarding against coercive interrogation. This right is fundamental in criminal law and is often cited in cases involving custodial questioning. It underpins the principle that the burden of proof lies on the prosecution. Justice Bhuyan invoked this article to argue that Kejriwals evasive answers did not justify arrest, emphasizing the constitutional protection of silence during investigations.

Why in news?

Article 20(3) was referenced in the Supreme Court judgment to uphold Kejriwals right to silence during CBI interrogation, influencing the dissenting view on the legality of his arrest.

Article 239A of the Constitution

Article 239A was inserted into the Constitution of India in 1963 to provide for the creation of local legislatures and councils of ministers in certain Union Territories. It originally applied to Puducherry, enabling it to have a Legislative Assembly and a Council of Ministers with powers similar to those of states. This article allows the President to make provisions for the administration of Union Territories by legislatures and councils, subject to Parliament’s laws. The application of Article 239A to Jammu and Kashmir in 2019 marked constitutional shift, extending legislative powers to the UT while maintaining central oversight through the Lieutenant Governor.

Why in news?

Article 239A was extended to Jammu and Kashmir in 2019, enabling the newly formed Union Territory to have a Legislative Assembly, marking the first elections since the abrogation of Article 370.

Article 348 of the Constitution of India

Article 348 governs the language of judicial proceedings in India. Clause (1) mandates that all Supreme Court and High Court proceedings be conducted in English unless Parliament legislates otherwise. Clause (2) allows a State Governor to authorize the use of Hindi or any other official State language in High Court proceedings, but only with the Presidents consent. This dual provision creates a constitutional framework balancing English’s primacy with regional language inclusion. Despite this, only a few High Courts currently use Hindi officially. The article reflects the complexities of language use in Indias judiciary, rooted in constitutional law and administrative procedure.

Why in news?

Article 348 is central to the ongoing debate on allowing regional languages in High Court proceedings, as recent parliamentary questions and government responses show efforts and challenges in changing the language policy.

Article 82A of the Constitution of India

Article 82A is a proposed new article introduced by the Kovind Committee to facilitate simultaneous elections for Lok Sabha and State Assemblies. It mandates that all Legislative Assemblies elected after the “appointed date” will end their terms simultaneously with the Lok Sabha. Article 82A allows the Election Commission of India (ECI) to recommend postponement of state Assembly elections if simultaneous polls are not feasible. Despite postponement, the Assemblys term will still end with the Lok Sabhas term. This article aims to synchronize election cycles through constitutional amendment and is part of the first Constitution Amendment Bill.

Why in news?

Article 82A was proposed as part of the constitutional amendments cleared by the Union Cabinet to implement simultaneous elections in India, following recommendations by the Kovind Committee.

Atomic Energy Regulatory Board (AERB)

The Atomic Energy Regulatory Board (AERB) is an Government of India agency responsible for regulating nuclear safety and radiation protection. Established in 1983, it functions under the Department of Atomic Energy but operates independently in regulatory matters. AERB reviews and authorizes nuclear facility designs, construction, and operations to ensure compliance with safety standards. It also oversees radiation safety in medical, industrial, and research applications. AERB conducts inspections, enforces safety protocols, and manages emergency preparedness for nuclear incidents.

Brahmaputra Board

The Brahmaputra Board was established in 1980 to manage flood control, bank erosion, irrigation, hydropower, navigation, and dam projects in the Brahmaputra River Basin, covering northeastern India and parts of West Bengal. It has suffered from chronic understaffing, with over 200 of 415 posts vacant, limiting its effectiveness. Attempts to restructure or replace it have been made, notably in 2012 and 2015, but political concerns, especially over dam construction in Arunachal Pradesh, stalled progress. The Board coordinates flood management but has struggled to meet objectives due to administrative and technical constraints.

Why in news?

The government plans to replace the Brahmaputra Board with Newma to address persistent issues like floods and erosion more effectively in the northeastern region.

Central Administrative Tribunal (CAT) Nainital Circuit Bench

The Central Administrative Tribunal (CAT) is a specialized body that adjudicates disputes related to public service employees in India.

It functions as an independent authority to oversee vigilance activities and recommend actions. The CVC can direct investigative agencies like the CBI to probe corruption complaints. It plays a key role in maintaining integrity within public administration by monitoring anti-corruption measures and reviewing cases. The CVC is not under the control of any ministry, ensuring operational autonomy. It was instrumental in directing the CBI to investigate the Coalgate scam following a political complaint.

Why in news?

The CVC ordered the CBI to investigate the Coalgate coal allocation scam, which is central to recent Supreme Court discussions on CBI independence.

Clean Acquittal

A clean acquittal refers to an accused being acquitted based on conclusive evidence proving innocence, not due to witnesses turning hostile or procedural flaws. It signifies a definitive judgment of innocence after trial. Clean acquittals are rare in Indias criminal justice system, where many acquittals result from technicalities or lack of evidence. The Supreme Court has recognized that prolonged detention of undertrials who later receive clean acquittals may violate their fundamental rights under Article 21 (right to life and liberty). Such cases may entitle the accused to compensation for wrongful incarceration.

Why in news?

The Supreme Court brought into light the injustice of prolonged detention followed by clean acquittal and suggested possible compensation claims for such undertrial prisoners.

Cognitive Cities

Free Movement Regime (FMR)

The Free Movement Regime (FMR) was a cross-border agreement allowing people living within 16 km of the India-Myanmar border to move without a visa. It facilitated trade, social, and cultural exchanges between border communities, including the Kukis spread across both countries. The regime was scrapped recently by the Government of India, citing security concerns. Its removal has created logistical and emotional difficulties for ethnic groups reliant on cross-border ties. The FMRs termination has deepened ethnic divisions, with Meiteis supporting border fencing and Kukis opposing it due to fears of community separation and disruption of traditional ties.

Why in news?

The scrapping of the FMR has intensified ethnic tensions in Manipur, as the Meitei community demands expedited border fencing while Kukis resist the move, fearing it will sever their cross-border connections.

Global Commons – Polar Regions and Outer Space

Global Commons refer to natural resources or areas beyond national jurisdiction, including the Arctic, Antarctica, outer space, and the high seas. No country owns these areas, but international agreements regulate their use to prevent exploitation. The Antarctic Treaty (1959) prohibits military activity and mineral mining, promoting scientific cooperation. The Outer Space Treaty (1967) bars national appropriation of celestial bodies and mandates peaceful use. These Commons are vulnerable to environmental threats and geopolitical tensions. Governance relies on multilateral frameworks to balance access, conservation, and sustainable use for all humanity.

They have jurisdiction over minor civil disputes like land and tenancy, and criminal cases such as theft and assault. These courts operate with simplified procedures and emphasize conciliation to resolve disputes amicably. Gram Nyayalayas are mobile courts, capable of conducting sessions at any location within their jurisdiction. Despite the legal framework, fewer than 500 gram nyayalayas have been set up, with only 314 operational, largely due to infrastructural, financial, and awareness challenges. They aim to provide speedy, affordable justice at villagers’ doorsteps.

Why in news?

The Supreme Court recently emphasized the need for better implementation of gram nyayalayas, denoting their inconsistent establishment and inadequate functioning across India.

Indias Digital Competition Bill
