The Public Liability Insurance Act of 1991 was enacted in response to major industrial disasters in India, mandating that entities dealing with hazardous substances must obtain liability insurance to protect the public from potential damages. The Act establishes a framework for compensating victims without the need to prove fault and outlines the responsibilities of owners handling hazardous materials, including the creation of relief funds. It also details penalties for non-compliance and mandates the involvement of various stakeholders to facilitate effective implementation.
