From Bichhri to Vellore: Tracing the Judicial Trajectory of the Polluter Pays Principle in India (1996–2025)

The Polluter Pays Principle (PPP) has emerged as a cornerstone of environmental jurisprudence in India, holding polluters financially and legally accountable for the harm they cause to the environment. This paper traces the judicial evolution of PPP from its foundational articulation in Indian Council for Enviro-Legal Action v. Union of India (1996), popularly known as the Bichhri case, to its reaffirmation and refinement in the recent Supreme Court judgment in Vellore District Environment Monitoring Committee v. Union of India (2025). The study investigates how the Supreme Court has progressively transformed PPP from a doctrinal import into a practical tool for environmental accountability and remediation. The principles’ theoretical foundation, along with their integration into India’s legal system, have been analysed in this paper, drawing from key cases the National Green Tribunal decided. The paper discusses the impact of the principle of PPP on the balance between economic development and environmental protection, taking into account the immediate impacts of climate change, pollution, and biodiversity loss, which India is facing. Thus, the paper aims to fully explain how the PPP has shaped and continues to influence the governance of the environment in India.
