Whole-mixture quantity rule under drug law upheld as a valid exercise of delegated power.

The NDPS Act permits the Central Government to notify small and commercial quantities, and Note 4 was upheld because it clarified that quantity must be assessed by reference to the entire mixture or solution, including the notified drug's dosage form and related variants where applicable. The court rejected the challenge of legislative overreach and excessive delegation, finding that the notification did not create a new narcotic drug or psychotropic substance but operated within the power conferred by the Act. It was issued to prevent offenders from avoiding the graded punishment scheme by mixing prohibited substances with other material.

Issues: Whether Note 4 inserted by the impugned notification, which requires quantity to be reckoned with reference to the entire mixture or solution and not merely the pure drug content, was unconstitutional or ultra vires the NDPS Act.

Analysis: The statutory scheme under the NDPS Act permits the Central Government to notify what constitutes small quantity and commercial quantity. The impugned note did not create any new narcotic drug or psychotropic substance, but clarified that the notified quantities apply to the entire mixture or solution of the relevant drug, including its dosage form, isomers, esters, ethers and salts wherever such existence is possible. The challenge based on legislative overreach and excessive delegation was rejected because the delegation itself was valid and the notification operated within the power conferred by the Act. The object of the amendment was to prevent persons from escaping the graded punishment scheme by combining prohibited drugs with other s.

Conclusion: The notification was held to be valid and not unconstitutional or ultra vires; the writ petition failed.
