India celebrates its second National Space Day on August 23, 2025, marking Chandrayaan-3’s success and upcoming missions, but lacks a comprehensive national space legislation to regulate and promote its growing space sector.

India’s Expanding Space Sector and Legal Gaps

Background

  • India has emerged as a major space power with missions like Chandrayaan-3, Gaganyaan, and the proposed Bharat Antariksh Station.
  • Despite progress, the absence of comprehensive national space legislation creates uncertainty for commercial and private actors.
  • India has ratified major UN space treaties, but has not yet enacted a domestic law aligning with these obligations.

Global Space Legislation Framework

  • Outer Space Treaty, 1967 (OST):
    • Declares space as the “province of all mankind.”
    • Prohibits national appropriation of outer space.
    • States bear responsibility for space activities of both government and private entities.
    • Companion treaties establish liability, rescue, registration, and moon agreements.
  • National Legislations:
    • U.S., Japan, Luxembourg have enacted laws facilitating licensing, commercial rights, and liability coverage.
    • Such frameworks ensure legal predictability and attract private investment.

India’s Current Approach

  • Incremental and Methodical Strategy:
    • Authorisation Frameworks Developed:
      • Indian Space Policy, 2023 – encourages private participation.
      • IN-SPACe Norms, Guidelines, and Procedures (NPG) – sets authorisation processes.
      • Catalogue of Indian Standards for Space Industry – ensures safety standards.
    • Pending Aspect:
      • A comprehensive “Space Activities Law” covering liability, licensing, accident investigation, debris management, and intellectual property rights.

Three new Bills propose to remove ministers facing criminal charges, raising concerns about misuse, political vendetta, and democratic implications.

Legal and Political Dimensions

  • State’s Discretion in Criminalisation: The state decides which acts are criminal, but its discretion risks being misused for political or partisan purposes.
  • Vulnerability of Politicians: Since 2015, as many as 193 cases against politicians have been registered by the Enforcement Directorate (ED), but only two convictions have occurred.
  • Judicial Concerns: The Supreme Court and High Courts have repeatedly expressed concerns over the low conviction rates and potential misuse of investigative powers.

Administrative and Democratic Concerns

  • Risk of Political Corruption: Bills enabling disqualification on the basis of mere charges or custodial detention may incentivize false cases against opponents.
  • Electoral Consequences: Such measures can curtail fair competition in elections by sidelining opposition leaders before due process of law is completed.
  • Threat to Federal Balance: Frequent interventions through central agencies like ED and CBI may undermine State governments’ functioning and autonomy.

Way Forward and Safeguards

  • Due Process Must Prevail:Any disqualification of elected representatives must follow judicial conviction, not mere allegation or charge-sheet.
  • Political Accountability Mechanisms:Parliament and political parties must strengthen internal accountability and ethical standards rather than bypassing judicial safeguards.
  • Comprehensive Reform Needed:Comprehensive reforms in criminal justice delivery, speedy trials, and electoral laws are essential instead of shortcut disqualification provisions.

Practice Question:

“Disqualifying ministers facing criminal charges through legislative shortcuts risks undermining democratic fairness and due process. Critically examine the challenges posed by such measures and suggest alternative reforms for ensuring political accountability.”     (250 words)

The Special Intensive Revision (SIR) of electoral rolls in Bihar has led to the deletion of nearly 3.5 million migrant voters (4.4% of total voters), raising concerns of large-scale disenfranchisement.

Structural Barriers in Electoral System

  • Sedentary-Centric Infrastructure: India’s voter registration is still based on proof of residence and in-person verification, which disadvantages migrants living in rented rooms, slums, or temporary sites.
  • Migrants’ Vulnerable Position: Migrants face dual exclusion: they cannot register in destination States due to outsider-tag and are being removed from origin rolls due to absence during verification.
  • Political Resistance in Host States: Fear of altered electoral outcomes, regionalism, and sub-nationalism discourages host States from facilitating migrant voter inclusion.

Democratic and Social Implications

  • Declining Voter Participation: Bihar’s average turnout in the last four Assembly elections was only 53.2%, the lowest among major States, reflecting the widening democratic deficit.
  • Triple Burden Identified by Study: A TISS-ECI study (2015) highlighted three barriers for migrants: administrative hurdles, digital illiteracy, and social exclusion.
  • Seasonal and Circular Migration Dynamics: Around 7 million circular migrants leave Bihar annually, with 2.7 million returning during festivals, but many will be unable to vote due to mass deletions from electoral rolls.

The Way Forward

  • Need for Portable Electoral Identity: India requires a portable and flexible voter identity system, enabling verification across origin and destination States.
  • Role of Local Governance and Civil Society: Panchayats and community bodies should conduct migrant-focused outreach and re-registration drives for ensuring democratic participation.
  • Replicating Kerala’s Migration Survey Model: High migration States like Bihar and Uttar Pradesh must adopt systematic migration surveys to track and protect voters’ rights.

Practice Question:

“Large-scale disenfranchisement of internal migrants highlights the tension between India’s sedentary electoral infrastructure and its mobile workforce. Discuss the challenges and suggest reforms to ensure inclusive electoral participation.”     (250 words)

Context:

Himachal Pradesh has lost 50% of its glacier area in the last 30 years, raising questions about development, resilience, and redefining prosperity.

Climate Challenges in the Himalayas

  • Melting Glaciers and Disasters: In Himachal Pradesh, rapid glacial melt has caused frequent floods, landslides, and road destruction, threatening lives and livelihoods.
  • Cascade of Uncertain Risks: Data indicates an indefinite series of cascading disasters, making future planning highly uncertain for the Himalayan region.
  • Redefining Development and Value: The crisis calls for a shift in the definition of prosperity, moving beyond economic growth towards ecological balance and resilience.

Psychological and Social Dimensions

  • Alarmism and Fatalism: Excessive focus on catastrophic projections creates numbness and fatalism, reducing people’s sense of agency to act.
  • Need for Constructive Narratives: Building hope-driven narratives that combine determination with wisdom can inspire communities to face challenges positively.
  • Role of Education and Awareness: Raising awareness through eco-sensitive education is vital for cultivating a generation capable of adaptive thinking and resilience.

Pathways for Future Action

  • Localised and Inclusive Solutions:Civil society organisations must scale up restoration and disaster-mitigation solutions to strengthen local resilience.
  • Multi-layered Response Strategy:Future planning must integrate climate fragility with development aspirations, ensuring sustainability in high-risk ecosystems.
  • Balancing Prosperity with Ecology:True prosperity lies in equitable development within ecological limits, demanding cooperation between governments, civil society, and citizens.

Practice Question:

“Alarmist narratives around climate change often paralyse communities instead of empowering them. In the context of Himalayan vulnerabilities, critically examine how development planning can balance ecological fragility with human aspirations.”   (250 words)
