GOODWILL PAINT AND CHEMICAL INDUSTRY vs UNION OF INDIA AND ANR.

The Supreme Court upheld the constitutional validity of Section 5 of the Poisons Act, 1919, affirming that it grants the State Government the authority to declare substances as poisons for regulation purposes. The Court ruled that the restrictions imposed on the possession and sale of such substances, including 'thinner', are reasonable and necessary for public health and safety. The judgment clarified that the definition of 'poison' is context-dependent, and the government has the power to regulate substances deemed dangerous to life under Section 2 of the Act.
