NITIN R. KANTAWALA vs UNION OF INDIA

The Supreme Court upheld the validity of the 'Delivery to Mail Order 1991' and the subsequent 'Delivery of Postal Articles Order, 1996', issued under Section 21(3) of the Indian Post Office Act, 1898. The Court rejected the appellant's argument that these orders were ultra vires the Act, clarifying that delivery to a mail box located in the building where the addressee resides is permissible under the Act. The Court held that the definition of 'house or office of the addressee' includes the entire building, thus affirming the High Court's decision.
