Could the POSH Act apply to political parties?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: POSH Act

Why in the News?

Recently, the SC considered a Public Interest Litigation (PIL) advocating for the applicability of the Sexual Harassment of Women at Workplace (Prevention, Prohibition, and Redressal) Act, 2013 to political parties.

What is the legal status of political parties concerning the POSH Act?

  • Current Legal Interpretation: The Kerala HC previously ruled that political parties do not fall under the scope of the POSH Act due to a lack of an employer-employee relationship with their members. This interpretation suggests that political parties are not obligated to establish ICCs as required by the Act.
  • Definition of Workplace: The POSH Act defines “workplace” broadly, including various public and private entities. However, applying this definition to political parties is complex, as many party workers operate without a defined workplace and often have temporary roles that do not align with traditional employment structures.
  • Potential for Inclusion: Advocates argue that since the POSH Act includes locations visited by employees during their course of employment, it could extend protections to party workers in field operations. The definition of “employee” also encompasses temporary and contract workers, which could potentially include political party members.

How can Internal Complaints Committees (ICCs) be effectively established?

What are Internal Complaints Committees (ICCs)?

ICCs are mandated bodies established under the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013 in India. These committees play a crucial role in addressing complaints of sexual harassment in the workplace, ensuring a safe and supportive environment for all employees.

  • Need for ICCs: The recent PIL presented in the court emphasizes that political parties should have mechanisms to address sexual harassment complaints in line with the POSH Act.
    • Currently, internal discipline mechanisms within parties may not adequately address issues of sexual harassment or comply with ICC requirements under the Act.
  • Challenges in Implementation: Creating ICCs within political parties poses challenges due to their non-traditional structures. The determination of who qualifies as an “employer” in this context is crucial for establishing accountability and compliance with the POSH Act.
  • Existing Party Structures: Political party constitutions outline hierarchical structures that could potentially facilitate the establishment of ICCs. However, these existing frameworks may not meet the requirements set forth by the POSH Act regarding membership and external oversight.

What role should the ECI play in enforcing compliance with the POSH Act?

  • Competent Authority: The Supreme Court directed that any grievances regarding the application of the POSH Act to political parties should first be addressed to the ECI, which is seen as the competent authority for enforcing compliance among registered political entities.
  • Historical Context: The ECI has previously been involved in ensuring compliance with other laws applicable to political parties, such as the Right to Information Act. However, its role concerning workplace harassment laws remains less defined.
  • Future Implications: If political parties are compelled to comply with the POSH Act through ECI directives, it could set a precedent for accountability and gender equality in politics, potentially influencing broader societal norms regarding workplace harassment.

Way forward: 

  • Strengthening Compliance Framework: The Election Commission of India (ECI) should issue clear guidelines requiring political parties to establish Internal Complaints Committees (ICCs) in alignment with the POSH Act, ensuring accountability and gender-sensitive grievance redressal mechanisms.
  • Legislative Clarification: Amend the POSH Act to explicitly include political parties within its scope, defining “employer” and “workplace” in the context of party structures to address the unique challenges of non-traditional workplaces.

The digital frontier of inequality

Note4Students

From UPSC perspective, the following things are important :

Mains level: Challenges related to digitalization;

Why in the News?

India’s digital revolution, with 1.18 billion mobile connections and 700 million Internet users, faces challenges from rising tech-facilitated gender-based violence. In response, the Ministry of Women and Child Development launched the ‘Ab Koi Bahana Nahi‘ campaign.

 

The “Ab Koi Bahana Nahi” campaign, launched on November 25, 2024, aims to combat gender-based violence in India. It promotes public accountability and action, coinciding with the global 16 Days of Activism.

How does the digital divide exacerbate existing socioeconomic inequalities?

  • Urban-Rural Disparities: There is a stark contrast in digital access between urban and rural areas. Urban regions enjoy better connectivity and higher internet speeds, while rural areas lag, limiting their ability to participate in the digital economy and access essential services.
  • Gender Inequality: The digital gender divide remains pronounced, with fewer women than men having access to digital technologies. This disparity restricts women’s economic and educational opportunities, reinforcing existing societal inequalities.
  • Economic Inequality: The lack of access to technology disproportionately affects lower-income groups, preventing them from improving their quality of life. Those without digital access are unable to compete in an increasingly online job market, leading to widening economic disparities.

What are the implications of digital inequality for education and unemployment opportunities?

Uniform Civil Code: Triple Talaq debate, Polygamy issue, etc.

What Ambedkar, KM Munshi said on Uniform Civil Code (UCC)?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Uniform Civil Code (UCC)

Why in the News?

Prime Minister renewed his call for a nationwide Uniform Civil Code (UCC), citing the views of Dr. B.R. Ambedkar and KM Munshi from the Constituent Assembly discussions.

What is Uniform Civil Code (UCC)?

  • UCC is envisioned under Article 44 of the Constitution, which calls for securing a UCC for all citizens throughout India.
    • Personal law subjects, including marriage, divorce, and inheritance, fall under the Concurrent List.
  • Hindu personal laws: Also applicable to Sikhs, Jains, and Buddhists as well, were codified by Parliament in 1956, encompassing: The Hindu Marriage Act, 1955 The Hindu Succession Act, 1956 The Hindu Minority and Guardianship Act, 1956 The Hindu Adoption and Maintenance Act, 1956.
  • Muslim personal matters are governed by the Shariat law of 1937.
  • The state refrains from interfering, and religious authorities decide based on Quran and Hadith.
  • UCC measures in India:
  1. Special Marriage Act, 1954: Permits civil marriage for any citizen, regardless of religion, allowing marriage outside religious customs.
  2. Shah Bano Case 1985: Supreme Court ruled in favour of Shah Bano for maintenance under Section 125 of CrPC, advocating for a UCC.
  3. Sarla Mudgal Judgement 1995 and Paulo Coutinho vs Maria Luiza Valentina Pereira case 2019: Supreme Court reiterated the need for implementing the UCC, urging the government to enact it.

What KM Munshi Said on UCC

  • Support for UCC: During the Constituent Assembly debate on November 23, 1948, KM Munshi advocated for the UCC. He rejected the argument that it would be tyrannical towards minorities.
  • Counterarguments: Munshi pointed out that advanced Muslim countries did not regard personal law as untouchable and had implemented civil codes.
  • Equality for Women: He emphasized that without a UCC, women’s rights in personal matters (like inheritance and succession) would remain unequal, particularly in Hindu law, which discriminated against women.
  • National Unity: Munshi linked UCC with national unity, stating that religion should be restricted to spiritual spheres and that social and civil matters should be regulated uniformly for the progress of the nation.

What Ambedkar Said on UCC

  • Support for UCC: Dr. B.R. Ambedkar, in the debate, did not delve into the merits or demerits of a UCC but strongly supported Article 35 (which was later renumbered as Article 44 of the Constitution of India), which called for securing a uniform civil code for citizens.
  • Challenging Religious Personal Laws: He criticized the view that Muslim personal law was immutable and noted that regions like the North-West Frontier Province (pre-independence) followed Hindu law for issues like succession.
  • State Power and Personal Law: He argued that religion should not govern personal laws and that the State had the right to legislate and reform social systems to address inequities and discriminations in personal laws.

What happened at the end of the Debate?

  • Passage of Article 35: After discussions, Article 35 was passed by the Constituent Assembly. This article laid down the directive principle that the State shall endeavor to secure a UCC for the citizens of India.
  • Renumbering to Article 44: Later, this article was renumbered as Article 44 in the Indian Constitution. It continues to remain a Directive Principle of State Policy (DPSP), guiding future policies on personal laws and advocating for uniformity in civil matters across religious communities.

Climate Change Impact on India and World – International Reports, Key Observations, etc.

First Ice-Free day in the Arctic could come by 2030: Study

Note4Students

From UPSC perspective, the following things are important :

Prelims level: De-glaciation of Arctic

Why in the News?

A recent study suggests that the Arctic Ocean may experience its first ice-free day—where sea ice falls below one million square kilometres—by 2030, or even sooner.

Key Highlights of the Study

  • First Ice-Free Day Prediction: The study predicts that the Arctic Ocean could experience its first ice-free day (less than one million square kilometres of sea ice) by 2030, or even sooner, depending on climatic conditions.
  • Simulations and Models:
    • 11 different climate models were used to run 366 simulations from 2023 to 2100 to assess the future of Arctic sea ice.
    • Most simulations predict the ice-free day within 7 to 20 years, with some models suggesting it could happen as early as September 2027.
  • Conditions for Ice-Free Day: The occurrence of an ice-free day will depend on a combination of unusually warm seasons and stormy weather, which accelerates the melting of the sea ice.
  • Impact on Sea Ice: Once the first ice-free day occurs, it could be followed by an ice-free period lasting between 11 to 53 days, potentially leading to the first ice-free month.

How does the Arctic Tundra store Carbon?

  • The Arctic tundra stores carbon primarily through a process where plants absorb carbon dioxide (CO2) from the atmosphere via photosynthesis.
    • This carbon gets trapped in the soil and organic matter (plants and animals) that accumulate over time.
  • The cold Arctic climate slows the decomposition of plant and animal remains, meaning that organic materials, including carbon, remain locked in the permafrost.
    • This permafrost acts as a natural storage system, preventing CO2 from being released back into the atmosphere.
  • Scientists estimate that the Arctic tundra holds about 1.6 trillion metric tonnes of carbon, which is roughly double the amount of carbon in the Earth’s atmosphere.

Why is the Arctic Tundra emitting more carbon than absorbing it?

  • Rising temperatures in the Arctic are causing the permafrost to thaw at an accelerated rate.
    • When permafrost thaws, microbes in the soil become active, breaking down the organic material trapped in the frozen ground, which results in the release of carbon dioxide (CO2) and methane (CH4), two potent greenhouse gases.
    • The Arctic has been warming at a rate four times faster than the global average.
    • 2024 was the second-warmest year on record for the region, contributing significantly to the thawing of the permafrost.
  • Wildfires in the Arctic have become more frequent and intense, further accelerating the thawing of permafrost. Wildfire smoke also contributes to the release of greenhouse gases.
  • Between 2001 and 2020, the combination of rising temperatures and increased wildfires led to the Arctic tundra releasing more carbon than it absorbed, marking a significant shift in its role from a carbon sink to a carbon emitter.

Why does it matter?

  • Climate Change Acceleration: The loss of sea ice will amplify the Albedo effect, causing the Arctic region to absorb more sunlight and heat, which will accelerate global warming and trigger extreme weather events in mid-latitudes.
  • Rising Sea Levels: The loss of Arctic ice contributes to sea level rise, with potential long-term impacts on coastal populations and ecosystems, particularly if the Greenland ice sheet melts completely, which could raise sea levels by 6 meters.
  • Ecosystem and Species Impact: The melting of sea ice will threaten species that rely on the ice for habitat, such as polar bears, walruses, and reindeer, disrupting the Arctic food chain.
  • Human and Infrastructure Threats: Arctic communities and their infrastructure are at risk as the region warms at four times the global average, threatening the livelihoods of people living in these areas.

Back2Basics: Albedo Effect

arctic albedo

  • It refers to the measure of how much sunlight is reflected by a surface.
  • It is expressed as a percentage; a surface with a high albedo reflects more sunlight, while a surface with a low albedo absorbs more.
  • Light-colored surfaces like ice and snow have high albedo, reflecting most of the sunlight, whereas dark surfaces like oceans and forests have low albedo, absorbing more heat.

 

PYQ:

[2022] Discuss global warming and mention its effects on the global climate. Explain the control measures to bring down the level of greenhouse gases which cause global warming, in the light of the Kyoto Protocol, 1997.

[2012] The increasing amount of carbon dioxide in the air is slowly raising the temperature of the atmosphere because it absorbs:

(a) the water vapour of the air and retains its heat
(b) the ultraviolet part of the solar radiation
(c) all the solar radiations
(d) the infrared part of the solar radiation
