Public Interest Litigation in Environmental Protection: Effectiveness, Emerging Trends and Contemporary Challenges

This paper evaluates the effectiveness of Public Interest Litigation (PIL) as a means of environmental protection in India, against the backdrop of perceived failures of the executive and legislative branches. Although the judiciary has expanded the scope of PILs from human rights to ecological preservation, enhancing transparency and accountability, the actual effect of these interventions is still under discussion. The research finds a continuing ‘implementation gap’ characterized by lack of public awareness and institutional resistance, building on an analysis of judicial trends and enforcement challenges. The findings reveal that while the Indian judiciary has successfully institutionalised doctrines like the "Precautionary Principle," the lack of a coordinated approach between grassroots movements and government authorities hinders long-term sustainability. The article concludes with a proposal for a dual-action framework for legal reform. Our findings indicate that while the Indian judiciary has been successful in institutionalising doctrines such as the “Precautionary Principle”, the absence of a synchronized approach between grassroots movements and government authorities leads to a lack of long-term sustainability. The paper concludes with a proposition of the dual action framework of legal reform and intensive public awareness campaigns to ensure that PILs are not just a reactive tool for environmental redressal.
