Step 1: Understanding the Concept:
The question describes the principle of Absolute Liability, a rule of tortious liability developed by the Indian Supreme Court. This principle is an evolution of the rule of Strict Liability (laid down in \textit{Rylands v. Fletcher}) but is far more stringent as it admits none of the exceptions available under strict liability.
Step 2: Detailed Explanation:
The principle of absolute liability was laid down by the Supreme Court in the landmark case of M.C. Mehta v. Union of India, AIR 1987 SC 1086. This case is also famously known as the Oleum Gas Leak case or the Shriram Food and Fertilisers case, as it involved a leak of oleum gas from a unit of Shriram Food and Fertilisers Industries in Delhi.
In this case, Chief Justice P.N. Bhagwati held that the rule of strict liability was outdated for modern industrial societies. The court formulated the new principle of absolute liability, the essence of which is captured verbatim in the question: enterprises engaged in hazardous or inherently dangerous activities have an absolute and non-delegable duty to ensure no harm results, and if it does, they are liable to compensate the victims without recourse to any of the traditional exceptions like 'act of God' or 'act of a third party'.
Step 3: Final Answer:
This principle was held in the Shriram food and Fertilisers case.
