Limited statutory definition of "Sikkimese" upheld as a valid expansion of exemption scope under income-tax law.

The amended Explanation to Section 10(26AAA) defines "Sikkimese" only for the limited purpose of the income-tax exemption, and Parliament's expansion of that term was treated as a matter of legislative policy and intent. The broader definition was held not to affect the expression for other purposes, and the challenge based on alleged dilution of Sikkimese identity was rejected. The writ petition was disposed of without interference, with the Court upholding the confined operation of the amended Explanation and its use only to determine eligibility for the statutory benefit.

Issues: Whether the amended Explanation to Section 10(26AAA) of the Income-tax Act, 1961, enlarging the meaning of "Sikkimese" for the purpose of the exemption, could be challenged on the ground that it diluted the identity of the Sikkimese people.

Analysis: The Explanation was held to define the expression "Sikkimese" only for the limited purpose of granting the statutory benefit under Section 10(26AAA). Expansion of the expression by Parliament was treated as a matter of legislative policy and parliamentary intent, and not as a basis for grievance by the petitioner. The clarification was also confined to the scope of the exemption and was not treated as affecting the expression for other purposes.

Conclusion: The challenge was rejected and no further interference was called for.

Final Conclusion: The writ petition was disposed of after upholding the limited operation of the amended Explanation and declining to interfere with the legislative expansion of the exemption.

Ratio Decidendi: Where Parliament expands the scope of an exemption provision by defining a term for that limited purpose, the validity or effect of that legislative policy cannot be questioned merely because the definition is broader than a pre-existing identity description.
